Als Ergebnis intensiver Suchaktionen durch Freunde, Bergrettung, Hundes- taffeln, Hubschrauber und Polizei, die leider erfolglos verliefen, muß davon ausgegangen werden, daß er durch einen Unfall im Gebiet des Pflegersees bei Garmisch in den Bayerischen Alpen ums Leben gekommen ist. Wie Sie alle wissen, hat sich Ernst Priesner seit vielen Jahren intensiv mit der Lockstoffsystematik beschäftigt und in dieser Fachdisziplin eine Weltspit- zenstellung eingenommen. Zahlreiche Fachkollegen hatten mit ihm Kontakt und unzählige gemeinsame Projekte wurden durchgeführt bzw. sind noch im Gange. Das mutmaßliche Ableben von Ernst Priesner ist nicht nur für die Wissenschaft ein unersetzlicher Verlust, es werden sich dadurch auch für viele Kollegen große Schwierigkeiten bei ihren weiteren Arbeiten ergeben. Deshalb gilt es sofort, den umfangreichen und für die Wissenschaft unersetz- lichen Nachlaß zu sichern, ihn sicher und übersichtlich zu lagern und für die Zukunft verfügbar zu halten. Ferner müssen alle Bemühungen dahin gehen, möglichst wenig Information aus nicht abgeschlossenen, laufenden Projekten zu verlieren und wichtige Daten jenen Kollegen zukommen zu lassen, deren Arbeiten beeinträchtigt werden oder ein Ende finden müssen. Das Max-Planck-Institut in Seewiesen sieht sich außerstande, die umfangreiche Bücher, Sonderdrucke, Karteien, handschriftlichen Notizen, Sammlungsteile, Negative, Fotos und Dias sowie die noch in den Labors vorhandenen Duft- stoffe und ihre Komponenten zu lagern und evident zu halten. Vielmehr wird dort dringend Labor- und Büroplatz benötigt. Nach Absprachen zwischen Frau Hedi Priesner, Prof.Dr. Kaissling, dem Ar- beitsgruppenleiter von Dr. Ernst Priesner am Max-Planck-Institut in Seewiesen, Dr. Gerhard Tarmann vom Tiroler Landesmuseum in Innsbruck und nach Genehmigung des Direktors des Institutes, Herrn Prof.Dr. Eberhard Gwinner, ging der gesamte Bestand, mit Ausnahme des chemischen Teils (Pheromone und die Substanzen zur Herstellung), geschlossen an das Tiroler Landesmuseum Ferdinandeum (Naturwissenschaften), da dort im neuerbauten Institut aus- 2 reichend Raum für eine Lagerung und Betreuung vorhanden ist. Die Bear- beitung der Bestände soll durch folgende Maßnahmen gesichert werden : 1. das Max-Planck-Institut leistet einen finanziellen Beitrag ; 2. das Tiroler Landesmuseum Ferdinandeum setzt seine Mitarbeiter zur Be- treuung der umfangreichen Literatur (hunderte Bücher, tausende Sonderdrucke und Kopien), der Sammlungen und des Fotoarchives ein und wird sich be- mühen, weitere Mitarbeiter für die Katalogisierung (EDV-mäßige Aufarbei- tung) zu bekommen ; 3. aus dem Verkauf von Literaturdoubleiten (Bücher und Zeitschriften, die am Ferdinandeum bereits vorhanden sind) sollen weitere Mittel zur Betreuung des Nachlasses, vorallem zur Katalogisierung und Evidenthaltung der zahllosen handschriftlichen Notizen und der Originalprotokolle aus den Gelände- und Laborarbeiten verfügbar gemacht werden ; 4. es wird ein Fond zur Bearbeitung des Nachlasses Ernst Priesner eingerichtet ; alle Kollegen, denen die rasche Aufarbeitung des wissenschaftlichen Nachlasses ein Anliegen ist, da sie Informationen daraus immer wieder brauchen bzw. jene, die durch die Verbindung mit Ernst Priesner wesentliche Impulse für ihre eigenen Forschungen erhalten haben, könne sich durch einen finanziellen Beitrag beteiligen ; 5. für die Aufarbeitung des Nachlasses sollen sachkundige Mitarbeiter stun- denweise engagiert werden. Der chemische Teil des Nachlasses muß in kompetente Hände gehen, das heißt, in eine Institution, die fachlich und personell in der Lage ist, mit den Substanzen zu hantieren und eventuell nach publizierten oder aufgefundenen Rezepturen Pheromone weiter zu produzieren. Diese Möglichkeiten sind am Ferdinandeum in Innsbruck nicht vorhanden. Durch Intervention von Dr. Nils Ryrholm aus Uppsala ist es gelungen, bei Dr. Peter Witzgall in Lund in Schweden eine solche Möglichkeit zu finden. So können die laufenden Projekte vielleicht doch noch einen Abschluß finden. Auch Prof. Clas Naumann in Bonn wird sich bemühen, mit seinen Mitarbeitern Teilgruppen organisatorisch zu betreuen (besonders Sesien- und Zygaenenpheromone). Wir möchten Sie bitten, falls sich für Sie wichtige Informationen in den vielen handschriftlichen Aufzeichnungen befinden, dies mit möglichst genauen Detail- angaben mitzuteilen. Nur so gibt es eine Chance, gezielt zu suchen und Ihnen Informationen rasch zukommen zu lassen. Bitte wenden Sie sich an Dr. Gerhard Tarmann, Tiroler Landesmuseum Ferdinandeum, Naturwissenschaften, Feldstraße 11a, Tel. : +43/512-587286 A-6020 Innsbruck Fax. : +43/512-58728640 Wir hoffen, mit diesen Aktivitäten und Ihrer Hilfe wenigstens die große wissen- schaftliche Lücke, die das mutmaßliche Ableben von Dr. Ernst Priesner für uns alle hinterläßt, so gering wie möglich zu halten. Dr. Gerhard TARMANN Summary Dr. Ernst Priesner, the well-known pheromone specialist, has been missing since the middle of July 1994, when he went to check some pheromone traps inthe Bavarian Alps, near Garmisch. Despite numerous search parties he could not be found and it must be assumed that he met with a fatal accident. Dr. Priesner’s contribution to pheromone research was immense and he led the world in the field of pheromone systematics. His research has resulted in an immense wealth of new faunistic and biological information. Many current scientific projects were dependent on his collaboration and their successful conclusion will now be very difficult. It was therefore considered imperative to save and make available the vast and irreplaceable scientific material he left behind. Apart from the chemicals, the entire contents of Dr. Priesner’s office and laboratory at the Max-Planck- Institute in Seewiesen, Bavaria, have been transferred to the Tiroler Landes- museum Ferdinandeum in Innsbruck, Austria, under the charge of Dr. Ger- hard Tarmann. This material consists of hundreds of books, thousands of scientific papers, card indexes, handwritten notes, photographs etc. A fund will be set up to finance the cataloguing and storage of the material. The Max- Planck-Institute will make a financial contribution and duplicate books will be sold. Donations to the fund are invited. The responsibility for the chemical contents of Dr. Priesner’s laboratory will be assumed by Dr. Peter Witzgall, Lund, Sweden, and Prof. Clas Naumann, Bonn, Germany will try to organise some of the projects (particularly those concerning sesiid and zygaenid pheromones). It is therefore hoped that the running projects can be brought to a conclusion. If anyone requires specific information from Dr. Priesner’s handwritten notes, he is invited to write to Dr. Gerhard Tarmann with as many details of the required information as possible. It is hoped that the measures taken will ensure that the loss caused by Dr. Pries- ner’s disappearance is kept to a minimum. Nota lepid. 17 (1/2) : 5-24 : 30.X1.1994 ISSN 0342-7536 Does ant-attendance influence development in 5 European Lycaenidae butterfly species ? (Lepidoptera) Konrad FIEDLER (!) & Christine SAAM Lehrstuhl für Verhaltensphysiologie, Theodor-Boveri-Biozentrum, Universität Würzburg, Am Hub- land, D-97074 Würzburg, Federal Republic of Germany Summary Caterpillars and pupae of 3 myrmecophilous (Aricia agestis, Polyommatus icarus, P. bellargus) and 2 myrmecoxenous lycaenid butterflies (Lycaena phlaeas, L. tityrus) were reared in the laboratory together with, or without, 2 species of tending Zasius ants (L. flavus, L. niger). Duration of development, mass gain, growth rates, prepupal and adult weights, and the ratio of mass gain per frass production were studied. There was no evidence for significant developmental costs associated with myrmecophily. Rather, we found some marginally beneficial effects of ant-attendance. Males of P icarus and L. phlaeas grew larger in the presence of ants. Mass gain per unit frass was slightly higher with ants in A. agestis (both sexes), P icarus and L. tityrus (males only). We found no consistent differences between the effects of the 2 ant species, nor between rearing treatments involving 2 or 5 L. flavus workers, respectively. Sexual and interspecific differences were documented in most of the parameters. These results show that certain myrmecoxenous and facul- tatively myrmecophilous lycaenid butterflies are able to compensate for their energetic costs associated with myrmecophily. The evolutionary consequences of such low-cost mutualisms are discussed. Zusammenfassung Raupen und Puppen von 3 fakultativ myrmekophilen (Aricia agestis, Polyom- matus icarus und P. bellargus) sowie 2 myrmekoxenen Bläulingsarten (Lycaena phlaeas, L. tityrus) wurden in Gegenwart von Ameisen (Lasius flavus bzw. L. niger) aufgezogen. Entwicklungsdauern, Wachstumsraten, Gewichte und Massenzunahme pro Kotproduktion wurden protokolliert. In keinem Fall ergab sich eine signifikante Beeinträchtigung dieser Parameter durch den Be- such von Ameisen und damit verbundene Sekretabgaben. Schwache positive Sn N correspondence should be addressed ; Tel. : 0931-8884321, Fax : 0931- Effekte konnten vereinzelt beobachtet werden (Gewicht der Männchen von P. icarus und L. phlaeas in Gegenwart von Ameisen größer, Massenzunahme pro Kotproduktion größer bei A. agestis, P. icarus und L. tityrus). Geschlechts- und Artunterschiede in den Entwicklungsparametern traten in den meisten Fällen auf. Die Ergebnisse zeigen, daß die untersuchten Bläulings-Ameisen- Interaktionen für die Schmetterlinge mit geringen, voll kompensierbaren Kosten verbunden sind. Die evolutive Bedeutung solcher Mutualismen mit niedriger Investition wird diskutiert. Resume Chenilles et chrysalides de 3 Lycénides myrmécophiles (Aricia agestis, Polyom- matus icarus et P. bellargus) et de 2 Lycénides myrmécoxènes (Lycaena phlaeas et L. tityrus) ont été élevées en laboratoire avec et sans 2 espèces de fourmis (Lasius flavus et L. niger). Les auteurs ont étudié la durée du développement, augmentation de taille, le taux de croissance, le poids des chenilles adultes et avant la chrysalidation, ainsi que l’augmentation de taille par rapport à la production d’excréments. Dans aucun cas, ils n’ont constaté une modification signicative de ces paramètres due à la visite des fourmis. Dans quelques cas, ils ont observé de faibles effets positifs de la myrmécophilie. Le poids des mâles de P icarus et L. phlaeas augmenta en présence des fourmis ; l’aug- mentation de taille par rapport à la production d’excréments fut plus marquée en présence des fourmis chez À. agestis (dans les deux sexes), P icarus et L. tityrus (mâles seulement). Les auteurs n’ont pas trouvé de différences consistantes entre les effets des deux espèces de fourmis, ni entre les élevages impliquant 2 ou 5 L. flavus (ouvrières). Des différences apparurent dans la plupart des paramètres du développement selon le sexe et l’espèce. Ces résultats montrent que les interactions Lycènes-Fourmis étudiées entraînent de faibles «coûts énergétiques», entièrement compensables. Les auteurs discutent de la signification évolutive de tels mutualismes «à faible coût». Introduction Many species of the butterfly family Lycaenidae live in association with ants throughout part of their larval and/or pupal stage (COTTRELL, 1984 ; PıERCE, 1987 ; FIEDLER, 1991). Ant-associations among lycaenids range from loose and unspecific, facultative interactions to obligatory and species-specific cases of mutualism or, rarely, parasitism. Typically, while feeding on their hostplants, the caterpillars attract ants with the help of chemical stimuli. This ant guard may provide protection against parasitoids or predators (PIERCE & EASTEAL, 1986; Pierce et al. 1987 ; but see PETERSON, 1993). Interactions between lycaenid immatures and ants are mainly mediated by secretions from specialized exocrine epidermal glands (MALIcky, 6 1969 ; CoTTRELL, 1984), although vibratory communication may be important in certain cases (DEVRIES, 1990). Three types of myrme- cophilous organs are known to play major roles. The dorsal nectar organ on the 7th abdominal segment, only present in larvae, secretes droplets of a clear liquid that contain carbohydrates and amino acids (Mascawirz et al., 1975; Pierce, 1983) upon tactile stimulation (TAUTZ & FIEDLER, 1992). So-called pore cupola organs, minute hair- derived glands distributed over the larval or pupal integument, appear to secrete amino acids or, in certain species, mimics of ant-pheromones (PIERCE, 1983). And the tentacle organs on the 8th abdominal segment of various lycaenid caterpillar species emit volatile compounds that cause an alerted behaviour in attendant ants (FIEDLER & MASCHWITZ, 1988 ; BALLMER & Pratt, 1992). All these secretions are produced at some energetic cost by the herbivorous caterpillars. In addition, the innervation and musculature of myrmecophilous organs and vibratory organs also cause metabolic costs. Previous studies on two lycaenid-ant systems demonstrated that ant- attendance may have a negative impact on larval and pupal develop- ment. In the obligatorily myrmecophilous Jalmenus evagoras (Dono- VAN, 1805) from Australia, ant-tended individuals develop faster than untended sisters, but attain lower weights (PIERCE et al., 1987). Larvae of J. evagoras are unable to compensate for nutrient loss to ants (BAYLIS & Pierce, 1992). As a consequence, myrmecophily is associated with significant fitness costs, since male mating success and female fecundity are strongly dependent on adult weight (ELGAR & Pierce, 1988 ; HILL & Prerce, 1989). In the Neotropical Arawacus lincoides (Draudt, [1919]), Rogsıns (1991) observed a slight retardation of larval develop- ment in response to ant-association, but weight was unaffected. Recently, however, beneficial effects of ant-attendance on larval develop- ment have been detected in three additional species. FIEDLER & HÖöLL- DOBLER (1992) found that ant-tended males of the Palearctic Polyom- matus icarus (Rottemburg, 1775) reach higher larval and pupal weights than untended controls. In the Nearctic Hemiargus isola (Reakirt, [1867]), tending by the ant Formica perpilosa enhanced caterpillar growth and thus adult weight, whereas two other ant species did not affect butterfly weight (WAGNER, 1993). These two butterfly species are facultative myrmecophiles, whose larvae associate with a variety of ant taxa and are not dependent on ant-association for survival. Overall, facultative myrmecophiles account for a larger proportion of the species diversity of the Lycaenidae than obligatory myrmecophiles (FIEDLER, 1991). Most recently, CUSHMAN et al. (1994) observed bene- ficial developmental effects in another Australian obligatory myrme- cophile, Paralucia aurifera (Blanchard, 1848). Hence, the prominent developmental costs of myrmecophily as found in J. evagoras might be atypical for the species majority. Therefore, a better understanding of the evolutionary and ecological significance of developmental costs or benefits arising from myrmecophily among Lycaenidae butterflies requires experimental work on a larger set of species from various taxonomic groups and representing all major types of myrmecophily. We here present the results of laboratory experiments with 5 European Lycaenidae species. Three of these possess all three types of myrme- cophilous organs and are facultative myrmecophiles, but show different degrees of myrmecophily. While mature larvae of Polyommatus bel- largus (Rottemburg, 1775) and Aricia agestis ([ Denis & Schiffermiiller], 1775) are rarely found without tending ants in nature, caterpillars of Polyommatus icarus are much less attractive to ants (e.g. THOMAS & LEWINGTON, 1991). P icarus was included to repeat the experiments of FIEDLER & HOLLDOBLER (1992) under a modified rearing regime. We also studied two myrmecoxenous species : Lycaena phlaeas (Lin- naeus, 1761) and L. tityrus (Poda, 1761). Larvae of these species neither possess a dorsal nectar organ nor tentacle organs, but they do have pore cupola organs. In laboratory experiments, weak and unstable ant- associations of these species can be induced and ants then harvest the PCO secretions (FIEDLER, 1991). Neither L. phlaeas nor L. tityrus larvae have hitherto been observed in association with ants in the field. Our aim was to investigate whether or not artificial ant-association involving two ant species and two different numbers of ants per indi- vidual lycaenid has any detectable effects on larval or pupal develop- ment. Furthermore, we wanted to know whether developmental effects differ between lycaenid species according to their degree of myrme- cophily. One might expect more distinct costs in caterpillars that are highly attractive to ants (P bellargus, A. agestis), whereas in myrme- coxenous species developmental costs should be absent or minimal. On the other extreme, secretion rates of obligatorily myrmecophilous caterpillars can be amazingly high (FIEDLER & MascHwirz, 1989 ; Fiedler, unpublished), corresponding to the pronounced developmental costs observed in species like the Australian Jalmenus evagoras (BAYLIS & Pierce, 1992). Finally, the developmental constraints on phyto- predacious lycaenid larvae parasitizing inside ant colonies (alike the Palaearctic Maculinea spp.) are entirely different (e.g. THOMAS et al, 1993, and references therein). Hence, a comparative survey across a larger number of species representing various stages of myrmecophily appears rewarding. 8 Material and methods Butterfly rearing Caterpillars were reared from eggs laid by field-caught (Aricia agestis, Polyommatus bellargus, P. icarus, Lycaena phlaeas, L. tityrus) or laboratory-bred females (A. agestis, P. icarus). Livestock originated from northern Bavarian populations except in ?. bellargus, where part of the experiments was conducted with individuals from southern France. Butterflies were kept in a greenhouse for oviposition or mating. Rearing procedures largely followed those described by SCHURIAN (1989). Eggs were collected every second day and transferred ınto a climatic chamber (25°C, 16:8 h L:D), where the whole development to adult eclosion took place. Groups of first instar larvae were placed in translucent plastic containers (125 ml) lined with moist filter paper. They were fed with cut foliage or inflorescences of appropriate host- plants : Geranium molle L. (Geraniaceae) leaves (A. agestis) ; Coronilla varia L. (Fabaceae) leaves (P. bellargus) ; Medicago sativa L. (Fabaceae) inflorescences (P. icarus); Rumex acetosa L. (Polygonaceae) leaves (Lycaena phlaeas, L. tityrus). Food was exchanged daily. Special care was taken to provide food of approximately equal quality ad libitum throughout the season, since food quality may affect larval myrme- cophily (FIEDLER, 1990 ; Bayis & Pierce, 1991). Ants Two ant species were used. Lasius niger (Linnaeus, 1758) is a common species of open grasslands and is well known to tend a number of lycaenid species in the field (FIEDLER, 1991). L. niger ants are omni- vorous ; they feed on insect prey and collect honeydew or similar energy-rich fluids. Lasius flavus (Fabricius, 1781) is also very common and lives largely subterranean in European grasslands. Its diet consists almost entirely of honeydew produced by root aphids. Because of their subterranean life, L. flavus ants rarely tend lycaenid larvae in nature, but they readily show trophobiotic interactions with lycaenid imma- tures in the laboratory (FIEDLER, 1991). Ant colonies were kept in the laboratory (at 22-26°C) in earth nests (L. flavus), or in artificial nest chambers the bottom of which consisted of plaster of Paris (L. niger). Ants were fed with honey-water and dead insects (mostly cockroaches) as needed. Experiments Experiments started at the beginning of the third larval instar, when the myrmecophilous glands of P icarus, P. bellargus and A. agestis 9 become functional. Experimental caterpillars were reared singly in translucent plastic vials (125 ml) equipped as above and were randomly subjected to one of the 4 following treatments: kept with 5 L. flavus workers ; with 2 L. flavus workers; with 2 L. niger workers ; and controls reared without ants. Food and filter paper were exchanged daily, and the entire larval frass was collected. Ants that had died during the experiment were replaced by nestmates to ensure a constant number of tending ants throughout. The procedure continued during the pupal stage. Daily inspections of every individual larva and pupa confirmed that all immatures of the 3 myrmecophilous species were constantly tended by their ant guard. In the 2 Lycaena species, ant-associations were likewise regularly observed, although occasionally larvae were seen without tending ants for short periods of time. Each experiment lasted until the adult butterfly eclosed from the pupa. All individuals that died prior to eclosion were discarded from the analyses. Mortality rates did not differ between the ant treatments within each species (SAAM, 1993). In total, 358 butterflies were reared to maturity (see SAAM, 1993 for further details). Every individual was weighed 5 times: at the beginning of the ex- periment (freshly moulted L3 : initial larval weight) ; as immobile non- feeding prepupa within a few hours prior to pupation (prepupal weight) ; as freshly moulted pupa (initial pupal weight) ; as fully pigmented pupa within 6 h before eclosion ; and as freshly eclosed adult after emission of the meconium (adult weight). The whole frass production over the third and fourth larval instar was collected, dried in an oven at 65°C to constant weight, and then weighed. All weights were recorded to the nearest 0.1 mg using an electronic Sartorius BA 61 balance. In addition, the durations of the third plus fourth larval instars and of the pupal stage were recorded (in days). From these data the following additional parameters were calculated : PERCENT PUPAL WEIGHT Loss : (Initial pupal weight - final pupal weight) x 100 / (initial pupal weight). Pupal weight losses always occur during development, but could be enhanced by the delivery of pupal secretions (e.g. from pore cupola organs) to ants. RELATIVE GROWTH RATE : RGR = (mass gained in the third plus fourth larval instar) / (prepupal weight X larval duration). The ratio : (larval mass gain) / (total frass production). This is a rough estimate for the efficiency of the conversion of ingested food into biomass. Assuming that the digestibility of food is not affected by the 10 presence of ants (see BayLis & PıErce, 1992), frass production is pro- portional to food consumption, if food quality is kept constant. The data were analysed statistically using ANOVA (with sex and treat- ment as factors) for multiple comparisons, and Mann-Whitney U-tests for comparisons between pairs of samples where normalıty or homo- geneity of variances were not met (SACHS, 1992). Percent data were arcsine-transformed prior to analysis. All P values given refer to 2-tailed tests. Results Duration of larval and pupal development The duration of the third plus fourth instar (Table 1) was largely unaffected by the presence of ants in A. agestis (mean values per experimental series 6-9 d), P. icarus (10-12 d), P bellargus (16-23 d), L. phlaeas (8-10 d) and L. tityrus (11-15 d). Sex differences in the duration of larval development occurred in all 5 species and in almost all treatments. Females generally took 1-2 d longer than males until pupation, but this difference was less distinct in experiments with ? icarus and L. phlaeas. The duration of the pupal stage was likewise not influenced by ant- association in all 5 lycaenid species tested. Sex differences in pupal duration were minimal (males faster in L. tityrus and P. bellargus). The pupal stage of A. agestis, L. phlaeas and L. tityrus took 7-8 d, that of P icarus 9-10 d, and in P bellargus pupal development lasted 11-13 d under the rearing conditions. Prepupal weights (Table 2) Caterpillar mass at the end of the larval stage was independent of ant-association in A. agestis (means 71-82 mg), P bellargus (means 107-126 mg) and L. tityrus (118-127 mg). P icarus males reared in the presence of ants (94.55 + 1.33 mg) were consistently heavier than control males (89.46 + 5.44 mg), although the difference was not signi- ficant. However, ant-association fostered a sex difference in P icarus. Males reared in the presence of ants were significantly heavier than females (U 3.3; = 195 ; Z = 2.825 ; P < 0.01), whereas control males and females reached equal prepupal weights (U7..; = 45; P > 0.5). A similar pattern occurred in L. phlaeas. Male prepupae reared in association with ants (89.6 + 3.05 mg) were significantly heavier than controls (73.8 + 2.34 mg; Ujo..4 = 38; Z = 3.099; P < 0.01), 11 xxx LO EL = A : X9S SU po 0 = 4 : SJUB supe 0 = A BEN su cdc =A : syue *86 9 = 4 DRS su 39°C = : syue su 90°] =H DER SU ÿ6 0 = 4 : syue *+L0 8 = A : X9S SU ÿL0 = 4 : SJuE 19974 (STD IEOF TE II (ZZ) 8t'0 F SI EI (ve) 91 0 + E98 (LZ) 81 0 F €£'6 (91) 89°0 F £9'8I (IT) SIO F 70T (TE) STOF L601 (TI STOFESII (ET) ITO + 6€ L (6€) IT’O + 9€'8 pauiquio9 SJU9U)E9I) JUV kkkCS OT = 4 XS SU 1l/.0=J4 : JU9UIJBII] «II =a WER SU OCT =A : Juaunean *90 7 =A Bros *16€ =A : JUS 91] +C6T =A Bros SU LEO = 4 : Juaumeaı] x*x* 16 CI = A 2 X9S MYC = al : JU90198297) Bela (ID) 80 FLTII (L) 890 F Er El (OL) 67 0 + 08'8 (S) 0r'0 + 0r'8 (2) L9'T + LS'61 (8) ITI F OS TC (L) LEO FLT (EI) SPOF 79'TI (8) SVOFSLL (LI) 0€ 0 + €S'8 syue }nOUJI M (8) I1L'0 F 00 ZI (6) LL'0 + 68 EI (9) LL’O + £8'8 (11) ¥7'0 + LT'6 () 91 I = 00'07 (2) OL'0 FrI'6l (ai) CEO 25 Zi (9) 290 = OS'II MOSES (L) PE 0 F PIE 1961U SNISVT 7 (L) 890 = ET'II (9) 9L'0 + LIYI (L) I£'0 + ££'8 COAAE 76 (p) EC'T F OS'9I (8) 91 I + 05°02 (8) WO F EIOI (3) I€ 0 FSLTI (6) 670 = 9S'L (LI) €€:0 £ 678 SNAD]{ snıspT 7 (SID LG OSE N (L) p80 F LSTI (LL) LTOFTL8 (L) ES'0 + LS'6 (8) €6°0 + 00°61 (AN SEAN (11) p70 $= 0011 (8) WO FOS II (L) 00 + 98°9 (SI) 9€°0 + L0'8 SNAD]{ snıspT S SOIN SO[PUIO SNA] DUAGDIAT se sofewa-] spovjyd puoosAT soe sopews] snd4D]]29 SNIDWL.IWLOAJOT SIM soewsg SNADI1 SNIDWWOAJOT sae sopewag SUS28D DIDI Sa199dS 010 < d SU: 1000 > d xxx: 100 > d xx: 600 > d x ‘ l'0 > d + ‘VAONV ABM-OMI Wry 918 SONJEA | ‘(S194981q ur Sois a[duues) SIOIIS PIepueIs F SULIT 218 UDAIDH ‘SJUE SN1SP7T JO S9U9Sq8 10 JoU9S91d au} ur PaIea1 USM sowads JepıuseaAT ueadomng ddl Jo (sAep ur ‘resur yJınoF snjd pa) JuswdopsAap [eA] Jo uoneinq I SIgeL SU 60 0 = 4 SCH Su C0 0 = 4 : que SU GI T—=4A : X9S kx8T 8 = A : jue xx08°L = 4 > XOS su 66 I =H : SJUB su OT =A : X9S su QL'0 = 4 : sjue x€9 =A : X9S SU T0 0 = 4 : syue Pape (ST) 0€ 7 F S6'07I (TI) Tr € F LL ETI (PT) SOE + 09°68 (LT) 90°€ + LO'E6 (CON Ret SSA (HHI (IT) LL'T + 9S'601 (LE) €€°1 F SS'H6 (EZ) 091 = L0'88 (ST) LP IF 60°€L (Zr) 6S IF PL SL pourquios SJU9U)291) UY su 770 =A : X9S su 860 =H : JusunNean su Cp | =H : X9S +80 € = A : Juauıyean kk80 8 = Æ : X9S suc] [| =H : JUSUIJESJI] xOT 6 = A : X9S SU 6€ 0 = A : Juowgean xxOL'L= A : X9S su C00 = 4 : Juawean IREM (11) 10°S F 9S IZI (DIGS 22 IGG!

A. agestis males were smaller than females, in P bellargus males were larger. In P. icarus and L. phlaeas, the sex difference was only apparent in ant-tended individuals (males larger than females, see above). Females and males of L. tityrus reached similar prepupal weights. Signi- ficant statistical ant-sex interactions were not observed. Pupal weight loss In all 5 species, ant-association had no detectable influence on pupal weight loss. Mean weight losses accounted for 15-20% in A. agestis, P. icarus and L. phlaeas, but were slıghtly higher in L. tityrus (> 20% in females) and highest in P bellargus (average values per series 23-28%). Sex differences in pupal weight loss were distinct only in L. tityrus (female pupae lost more weight [22-24% on average] than males [average loss 17-19%]). Otherwise, there were neither sex differences nor significant ant-sex interactions. Adult weights (Table 3) Adult weights were not affected by ant-association in A. agestis, P. bellargus and L. tityrus. In P. icarus, ant-tended males (35.07 + 0.76 mg) were ca. 10% heavier than untended controls (31.27 + 1.21 mg; Uz3, = 50 ; Z= 2.20 ; P < 0.02), whereas females showed no effect (ant- sex interaction : Fj.67 = 3.92 ; P < 0.05). A similar effect was observed in L. phlaeas : ant-tended individuals (especially males : 31.41 = 1.70 mg) eclosed from the pupae at higher weights than untended controls (23.65 + 0.85 mg). As a consequence, there was no significant sex dif- ference in adult weights of ant-tended P icarus and L. phlaeas, whereas untended controls of both species showed a distinct size dimorphism (females heavier than males). In A. agestis there was a significant sex difference independent of ant-association, females being heavier than males. No significant size dimorphism occurred in P bellargus and L. tityrus. Growth rates (Table 4) In all 5 species tested, males tended to grow faster than females. This difference was only weakly developed in P. icarus and L. phlaeas, but was pronounced in the remaining 3 species. Only in A. agestis was there a weak trend that caterpillars in association with 5 Lasius flavus ants grew slightly faster than all others.

Relative growth rates (daily mass gain divided by prepupal mass) were 0.10-0.13 mg/mg * d in A. agestis and L. phlaeas, 0.07-0.09 mg/mg * d in P icarus and L. tityrus, and 0.045-0.05 mg/mg * d in P bellargus. Frass production and efficiency of food conversion (Table 5) The ratio of larval mass gain (wet weight) and frass production (dry weight) was at most weakly affected by ant-association in all 5 species. In P bellargus, this ratio was lower in the experimental series with 2 L. niger ants. This series was reared later in the season than all others, and the differences most likely indicate a change in hostplant quality rather than any influence of ant-tending. In A. agestis, L. phlaeas and L. tityrus, no consistent effects of ants were found. For P. icarus, ANOVA indicated no influence of ant-association on food utilization. However, ant-tended males had a significantly higher mass gain/frass ratio than ant-tended females (U;,33, = 170; Z = 3.26; P < 0.002), whereas in control experiments this sex difference did not occur (U); = 34; P > 0.2). Overall, sex differences in this parameter were minimal, and average values for the treatments ranged from 1.34- 1.52 mg/mg in A. agestis, 1.70-2.05 mg/mg in both Polyommatus species, and 3.30-4.97 mg/ mg in the two Lycaena species. Discussion Differences in developmental parameters between males and females were observed in all 5 species tested. Generally males developed faster (shorter larval period, higher growth rate). This is in accordance with the protandry of all 5 species in nature. All species examined produce 2 or more generations per year in central or southern Europe. The most rapid development was observed in A. agestis and L. phlaeas. These two species produce 3-4 generations per year in central Europe in favourable seasons. P. icarus was somewhat slower (2-3 generations per year), and L. tityrus as well as P. bellargus took longest to reach maturity. In the latter two species a third generation is a very rare exception north of the Alps (EBERT & RENN- WALD, 1991). Thus, our laboratory results are consistent with pheno- logical observations made in the field. Pupal weight losses were highest in P. bellargus, the species with the longest pupal stage, and were fairly similar among the remaining 4 species. Concerning the ratio of mass gain per frass production, the two myrmecoxenous Lycaena species far surpassed the 3 myrme- cophilous members of the Polyommatus group. Both Lycaena species 18 feed on leaves of Rumex species (Polygonaceae). These leaves appear to have a lower content of undigestible material than the legume hostplants of P icarus or P. bellargus. PıErce (1985) has argued that myrmecophily has selected for the utilization of nutrient-rich hostplants (especially nitrogen-rich legumes and inflorescences), but obviously the 2 Lycaena species perform in a superior manner on the foliage of a non-legume host. According to its biomass/frass ratio, A. agestis utilizes the poorest hostplant material (leaves of Geraniaceae), but nevertheless the caterpillars are highly myrmecophilous. The nutritional constraints on larval myrmecophily are a rewarding field open to further inves- tigation (BAYLIs & PIERCE, 1993). Overall, ants had very little impact on the developmental parameters studied, and the few marginally significant ant-effects which could be detected were mostly beneficial. From facultatively myrmecophilous Lycaenidae butterflies like Polyommatus icarus or Hemiargus isola it is already known that ant-association does not necessarily pose develop- mental costs, but may even allow overcompensation of the investment into myrmecophily (FIEDLER & HÖLLDOBLER, 1992 ; WAGNER, 1993). Our present data fully corroborate that pattern. Aricia agestis and Polyommatus bellargus are both facultative myr- mecophiles whose older larvae are almost never found without tending ants (e.g. THOMAS & LEWINGTON, 1991). In these species, ant- association had very limited effects on developmental parameters, suggesting that larvae of both sexes can fully compensate for the costs of myrmecophily. In recent experiments with A. agestis, we could even demonstrate a beneficial effect of ant-attendance on prepupal weights (tended individuals are ca. 10% heavier, but develop more slowly: Hummel & Fiedler, unpublished). Polyommatus icarus is a facultative myrmecophile with a rather loose relationship to ants (THOMAS & LEWINGTON, 1991). Caterpillars of this species produce less secretion from their nectar organs than P. coridon and its close relatives (FIED- LER, 1991), suggesting a comparatively low energetic investment into myrmecophily. Our experimental data confirm the findings of FIEDLER & HOLLDOBLER (1992) that ant-tended P. icarus males grow larger than untended controls, whereas tended females appear to fully compensate for their costs of myrmecophily. Weak male-limited benefits also occurred in myrmecoxenous Lycaena species (weight in L. phlaeas, food conversion in L. tityrus). Caterpillars of both species lack a dorsal nectar organ. Accordingly, their energetic investment in interactions with ants must be low (only through the ubiquitous pore cupola organs). Ant-associations of these species are 19 unknown in the wild, but under laboratory conditions weak and unstable associations can be induced (FIEDLER, 1991). As in the case of certain ant-tended aphids which show better growth in the presence of ants (Banks & Nıxon, 1958), the physiological mechanisms responsible for overcompensation in some lycaenid cater- pillars remain unclear. Ant-tended caterpillars did not produce more frass than untended controls (SAAM, 1993). Therefore, total food consumption was probably equal between the groups. Rather, the efficiency of food conversion into biomass may be stimulated by tending ants. Circumstantial evidence for this hypothesis was found in A. agestis, P. icarus and L. tityrus, where ant-tended individuals showed enhanced conversion of food. Alternatively, the stimulation of caterpillars could be a predominantly behavioural phenomenon (see discussion in WAGNER, 1993). Perhaps feeding behaviour is less often interrupted in ant-tended individuals, facilitating a more effective food utilization. Caterpillars of P icarus, P. coridon and other myrmecophilous species resume locomotion and feeding more rapidly after experimental disturbance when ants are present (Fiedler, unpublished). In the Nearctic Glaucopsyche lygdamus (Doubleday, 1841), untended caterpillars are much more likely to drop off the hostplant (PIERCE & EASTEAL, 1986). Developmental effects of ant-attendance have not been studied in detail in this latter species, but pupal weights of tended and untended individuals did not differ (PIERCE & EASTEAL, 1986). One could argue that, under the confined conditions of artificial ant- associations, ants do not harvest larval secretions as eagerly as they would do if they could transfer their crop content to their colony. Three lines of evidence contradict this view. Firstly, caterpillars and pupae of all 5 species tested were regularly tended by ants (and the 3 myrmecophilous species constantly so) throughout the whole experi- mental period. Tending levels did not decrease with time. This indicates that the ants, which had no access to alternative food sources, exerted a permanent pressure on the lycaenid immatures to deliver their secretions. Secondly, in P icarus (and in the myrmecoxenes L. phlaeas and L. tityrus) the numbers of ants per larva used in our experiments were comparable to, or even higher than, the average number of tending ants observed so far in nature. Hence, at least in these species com- pensation or overcompensation occurred despite a relatively high level of ant-attendance. Thirdly, the amounts of nectar secretion produced by single lycaenid larvae over the third plus fourth instar are sufficiently small to be 20 sampled completely by a small number of ant workers. In P. icarus and A. agestis, for example, individual lifetime nectar secretion volumes amount to 10 ul or less, equivalent to approximately 1.5 mg carbo- hydrates at most (Fiedler, Burghardt & Hummel, unpublished). How- ever, we cannot rule out the possibility that ın future experiments (e.g. with higher tending levels or involving other ant species) deviating results could be obtained. The actual outcome of potentially mutualistic interspecific interactions can be strongly shaped by environmental conditions such as hostplant quality or density of interacting species (CUSHMAN & WHITHAM, 1991 ; BRETON & ADDICOTT, 1992). There is steadily increasing evidence that compensation or even over- compensation of the energetic costs resulting from ant-association is not uncommon among facultatively myrmecophilous lycaenid butterf- lies. This finding could explain why facultative, and sometimes weak, interactions with ants are so common and taxonomically widespread across the diversity of Lycaenidae butterflies (FIEDLER, 1991). If myr- mecophily were generally a high-cost strategy under severe selective regimes, one would have to expect strong disruptive selection favouring either close and obligatory myrmecophily with high costs, but high rewards for the lycaenids, or favouring the reduction of myrmecophily. In contrast to this expectation, facultative ant-associations appear to be more common in lycaenid butterflies than cases of obligatory myr- mecophily (PIERCE, 1987 ; FIEDLER, 1991). Many examples of facul- tative interactions with ants are probably best described as low-cost mutualisms, where the lifetime energetic investment of individual cater- pillars accounts for a few ul of secretions. It is then not surprising that myrmecophily is an evolutionarily rather stable component in the life-history of so many Lycaenidae species. A broad continuum of cost-benefit relationships in terms of myrme- cophily does exist across the diversity of Lycaenidae butterflies. This is reflected by the variety of developmental effects these ant-association can have in various lycaenid species, ranging from severe costs to substantial benefits. In general, the developmental costs for the larvae appear to parallel the degree of obligateness of the ant-lycaenid asso- ciations : the more dependent the larvae are on ants, the higher the costs the ants can in turn impose. Further comparative studies on species representing various taxonomic groups and different types of myrmecophily will strengthen our ecological and evolutionary under- standing of lycaenid-ant interactions. 21 Acknowledgements We are indebted to U.

SCHURIAN** * Theodor-Boveri-Biozentrum der Universität, Zoologie II, Am Hubland, D-97074 Würzburg, Germany ** Am Mannstein 13, D-65779 Kelkheim-Fischbach, Germany Summary The oviposition behaviour of Lycaena thetis was observed in the Aladag mountains, southern Turkey. Females drop their eggs singly into the spiny cushions of the larval foodplant (Acantholimon spp., Plumbaginaceae). Zusammenfassung Das Eiablageverhalten von Lycaena thetis wurde im Aladag-Gebirge (Süd- Türkei) beobachtet. Die Weibchen lassen ihre Eier einzeln in die dornigen Kugelpolster ihrer Wirtspflanze (Acantholimon spp., Plumbaginaceae) fallen. The life histories of European or North American species of the Lycaenini (“Copper butterflies”) are, in general, well known. For most Asian Lycaena Fabricius, 1807, species, however, even basic biological information on hostplants, voltinism, or diapause stages is lacking (cf. FIEDLER, 1991). Recently, ToLMAN (1993) published a detailed account of the larval biology of Lycaena thetis Klug, 1834, from southern Greece. Since Tolman based his description on field-collected young, hibernated larvae, the oviposition behaviour of L. thetis remained unknown. Furthermore, Tolman’s paper deals with the westernmost populations of L. thetis. Because the distribution of L. thetis extends throughout Asia Minor to northern Iran (SCHURIAN & HOFMANN, 1982), it remained to be tested whether populations in the heart of the species’ range utilize the same or similar hostplants. On 15.vi.1993, between 11.00-15.00 EEST, we had the opportunity to observe the unusual oviposition behaviour of L. thetis in a population of southern Turkey. The habitat was a south-facing steep slope in a valley of the Aladag mountains (Prov. Nidge), approximately 1800- 25 1900 m above sea level. This slope was mostly covered by limestone boulders and scree. The sparse vegetation contained Juniperus shrubs and single conifer trees. Spiny, cushion-forming, perennial plants (Astragalus and Acantholimon spp.) which are relatively immune to overgrazing by the abundant sheep and goats, formed the lower vegetation between the boulders. # É # ft À mit 4 # Fig. 1. Large contiguous cushions (total diameter > 1 m) of Acantholimon sp. (Plum- baginaceae), the hostplant of Lycaena thetis. When we first walked through the habitat late in the morning, only few territorial males and nectaring females of L. thetis were on the wing. Males preferably basked on barren ground. Around noon, when the air temperatures had reached about 30°C, females became increa- singlv active. They often visited the last flowers of Acantholimon spp. (Plumbaginaceae). This cushion plant with extremely spiny, needle- like leaves (Fig. 1) is the hostplant of L. thetis in Greece (TOLMAN, 1993), although we were unaware of his paper at the time of our observations. Females examined the Acantholimon cushions in the fluttery searching flights that typically precede oviposition in many lycaenid butterflies. After alighting, each female would crawl about on the cushions for several minutes, repeatedly curling its abdomen 26 and probing the plant surface with the antennae and ovipositor. However, despite intensive close examination of the respective plants after the females had flown off, we failed to find any eggs attached to the twigs or leaves. Finally, we succeeded in observing the actual oviposition act. When viewed in contre-jour, we could clearly see that after up to 5 minutes of intensive crawling and probing the hostplant, the female eventually inserts its ovipositor between the needle-like leaves and simply drops a single egg into the cushion. In one case, the egg by chance stuck to a twig deep within an Acantholimon cushion, but unfortunately it fell to the ground during our attempt to secure it. The hemispherical egg was rather large (ca. | mm in diameter) and showed the rough chorionic sculpturing typical for Lycaena eggs. In total, we observed 10 successful oviposition acts, all in the same manner. On at least twice as many occasions, a female left the hostplant without laying an egg. Ovipositions only occurred during the hottest hours around noon. When we left the habitat (15.00), the females tended to bask for long periods on the Acantholimon cushions, and flight activity evidently decreased. We followed various individual females for dozens of metres. These females ignored many potential hostplant cushions and alighted to probe quite a number of Acantholimon plants before an egg was laid. Hence, they appear to be very choosy, but we do not know the factors that finally elicit oviposition. Egg-laying occurred on small as well as on large plants (0 = 30-100 cm) and not invariably in full sun, although high temperatures are clearly required. All eggs were dropped into the central part of a cushion, not at the edges. To obtain oviposition in captivity, we collected a total of 10 females from various habitats in southern Turkey in August 1993. These were caged in a plastic bottle (1.5 1) lined with moist filter paper, twigs of the hostplant Acantholimon as oviposition substrate, and sugar solution as food. However, despite exposing the females to various conditions (direct sunlight, shadow, high temperatures, high or low humidity), not a single egg was laid. The last female died after 14 days in captivity. When earlier attempting to obtain eggs from L. thetis in captivity (1977 and 1984), females had been confined with an erroneously presumed hostplant (Rumex sp., Polygonaceae) without any success. Our failure to induce oviposition in captivity contrasts sharply with successful attempts involving various other Lycaenidae species (Lycaena candens (Herrich-Schäffer, 1844), Agrodiaetus spp., Polyommatus spp.) under similar conditions. Females of L. thersamon (Esper, 1784) (like L. thetis, often assigned to the “subgenus” Thersamonia Verity, 1919), however, 2 laid only few eggs, suggesting that in both species highly xerothermic conditions (and presumably unknown factors) are essential for egg- laying. Dropping the eggs instead of attaching them onto the hostplant is a very rare behaviour in Lycaenidae butterflies, but has been recorded from the Nearctic Lycaena rubidus (Behr, 1866 ; see Funk, 1975). In L. thetis, the females may thereby avoid fatal injuries inflicted by the extremely spiny leaves, and the eggs are probably protected against many enemies within the dense thorny Acantholimon cushions. It re- mains to be proven whether L. thetis hibernates in the egg stage or whether the larvae hatch in late summer to diapause. Both strategies occur within the genus Lycaena. Since TOLMAN (1993) found larvae of 4-7 mm length shortly after hibernation in Greece, diapause as a young caterpillar seems more likely. Our observations confirm that Acantholimon is the hostplant not only for Greek, but also for Turkish L. thetis populations. The plant family Plumbaginaceae is well represented in eremic steppe habitats. In addition, Plumbaginaceae are not too distantly related to the usual Polygonaceae hostplants of most Lycaena species (both plant families belong to the subclass Caryophyllidae). SCHURIAN & HOFMANN (1982) explicitly mentioned the presence of Acantholimon (in part quoted as “ Acantolimnus”) in habitats of L. eberti Forster, 1972, and LUKHTANOV & LUKHTANOV (1994) recorded the hostplant of L. solskyi (Erschoff, 1874) as Acantholimon. Therefore, additional species of Asian Lycaena might also use Acantholimon as hostplant. Fucus (1989) reported that L. thetis (especially females) preferably visited another spiny cushion plant, Drypis spinosa (Caryophyllaceae), in central Greece for nectaring and basking. Whether this plant species could serve as alternative larval hostplant, needs to be demonstrated. References FIEDLER, K., 1991.

The third volume of this major work on the Australian Lepidoptera fauna deals with the genera of the subfamily Oecophorinae. With 1886 valid named species and an estimated species total of more than 5000, the Oecophorinae is by far the best represented group of Lepidoptera in Australia. The wealth of species in Australia is disproportionate, being about 70% of the world fauna. With 170 named genera and an estimated total of 275, clearly all cannot be treated in a single volume. The present volume is the first of three parts and covers the 91 genera of the Wingia group. The author is well-known for his excellent book ‘Moths of Australia’ (see review in Nota lepid. 14 (3) : 292). As in the previous volume, introductory chapters on ‘Phylogeny’, including a tentative phylogenetic analysis of the subfamily genera, ‘Morphology’, ‘Biology’ and ‘Diversity and Distribution’ are given. The only synapomorphies of the Wingia group are to be found on the ab- dominal sternum and in the male genitalia. It is not stated however whether an experienced lepidopterist can recognise most species belonging to this group on external characters only. A key to the genera is provided, based on external and internal morphological features. The treatment of each species follows the same format as in the previous volume (for review, see Nota lepid. 16 (3/4) : 265-266). The high scientific quality of the series is maintained in this volume and as such can be highly recommended to students of this family or of the Australian Lepidoptera fauna in general.

Until recently, the genus was considered to be monotypical, with M. interpunctaria (Herrich-Schäffer, 1839) the only known species. Zusammenfassung Myinodes interpunctaria (Herrich-Schaffer, 1839) war in der Literatur bisher stets als einzige Art (Typusart) der Gattung Myinodes betrachtet worden. Eine genauere morphologische Analyse ergab, daß die aus Nordafrika, Südeuropa und Vorderasien bekannten Populationen einen aus mehreren verschiedenen Arten bestehenden Komplex bilden. In der vorliegenden Arbeit werden zwei neue Arten und eine neue Unterart beschrieben : Myinodes interpunctaria atlantica ssp. n. aus Spanien, Myinodes constantina sp. n. aus Algerien und Myinodes shohami sp. n. aus Jordanien. Resume Description de deux nouvelles espèces et d’une nouvelle sous-espèce du genre Myinodes Meyrick, 1892 : Myinodes interpunctaria atlantica ssp. n. d’Espagne, M. constantina sp. n. d’Algerie et M. shohami sp. n. de Jordanie. Jusqu’a tout récemment, ce genre était considéré comme monotypique avec M. interpunc- taria (Herrich-Schäffer, 1839) comme seule espèce connue. Until recently, the genus Myinodes Meyrick, 1892 was considered to comprise only the species interpunctaria (Herrich-Schäffer, 1839). De- tailed morphological studies have revealed, however, that the popu- lations known from northern Africa, southern Europe and the Middle East constitute a complex of different species. In this paper two new Sil species and one new subspecies are described : Myinodes interpunctaria atlantica ssp. n. from Spain, Myinodes constantina sp. n. from Algeria and Myinodes shohami sp. n. from Jordan.

Available from: The London Natural History Society, Publication sales secretary, 3 Chats- worth Gardens, West Harrow, Middlesex HA2 ORS, UK. Price: 19295 This volume can be considered to be the sequel to ‘The butterflies of the London area’ produced by the same author in 1987. It is however very different in both format and content. The moth volume has a much larger format, there are no coloured photographs and several species are treated per page. It will therefore not be attractive to the general public; the ‘moth hunter’ however will find this book extremely interesting and useful. The London area is defined as that area within 20 miles from St. Paul’s Cathedral. All available records have been collated, but on the distribution maps, only the data obtained between 1980 and 1991 are plotted, although the older records are given in the usual way (open circles) for the rarer species. A transparent overlay with maps showing the built-up areas, woodland and chalk is provided. Over this ten year period, 84% of the 856 tetrads (a tetrad = 2 x 2 km) have been covered, although to varying degrees — a remarkable achievement. A total of 715 macrolepidoptera have been recorded from this area, although 66 were not noted during the ten year recording period. The text for each species is very readable, and reminiscent of that in South’s ‘Moths of the British Isles’. Foodplants known to have been recorded within the area are listed for each species, and also the years of the oldest and most recent records. Appendices give a check list of species for each vice-county in the area, the National Red Data List category, and the number and percentage of tetrads in which each resident species was recorded. This work will undoubtedly be a very valuable tool for London naturalists, conservation officers and lepidopterists. It provides an ideal basis for further studies and the author and record contributors are to be congratulated on their efforts. Their example should be followed. S. WHITEBREAD 44 Nota lepid. 17 (1/2) : 45-52 ; 30.X1.1994 | ISSN 0342-7536 Geographical varıation in wing pattern of Micropterix maschukella Alpheraky, 1876 (Lepidoptera : Micropterigidae) Michail V. Kozıov Laboratory of Ecological Zoology, Department of Biology, University of Turku, FIN-20500 Turku, Finland Summary Five discrete types of forewing pattern can be found within populations of Micropterix maschukella Alphéraky. In Lagodekhi, Eastern Georgia, frequen- cies of wing pattern types were the same for males and females ; no differences were found between the two study years. The frequency of wing pattern type was therefore considered to be a population specific character and was used to study geographical variation. Phenetic resemblances of 15 samples from the Crimea and Caucasus correspond in general to the spatial proximities of the sampling sites. Three geographically consistent units were distinguished : northern (Crimea and Krasnodar district), south-western and eastern. A clear allopatric differentiation within the species was found, but there was no corre- sponding variation in the male genitalia. Resume Parmi les populations de Micropterix maschukella Alphéraky, on trouve cinq types discrets de dessin des ailes antérieures. A Lagodekhi, Georgie orientale, la fréquence des types de dessins des ailes est la même pour les mâles et les femelles ; on n’a pas trouvé de différences entre les deux années de l'étude. La fréquence des types de dessin des ailes a donc été considérée comme carac- téristique des populations et utilisée pour étudier la variation géographique. Les ressemblances phénétiques de 15 échantillons de Crimée et du Caucase correspondent en général aux proximités spatiales des sites des échantillons. Trois unités géographiques consistantes ont été distinguées : nord (Crimée et région de Krasnodar), sud-ouest et est. On a constaté une nette différenciation allopatrique dans cette espèce, mais pas de variation correspondante dans les genitalia mâles. | Zusammenfassung In Populationen von Micropterix maschukella Alpheraky lassen sich fünf Typen der Vorderflügelzeichnung unterscheiden. In Lagodekhi, Ost-Georgien, 45 werden diese Zeichnungsmuster-Typen bei Männchen und Weibchen mit glei- cher relativer Häufigkeit beobachtet ; zwischen den beiden Untersuchungsjahren gab es hierbei keine Unterschiede. Die relativen Häufigkeiten der Zeichnungs- muster-Iypen wurden daher als populationsspezifisch betrachtet und als Maß für geographische Variabilität verwendet. Das Erscheinungsbild von 15 Sammel- proben von der Krim und aus dem Kaukasus läßt sich im allgemeinem mit den räumlichen Abstand der Fundpunkte in Beziehung setzen. Drei geographische Bereiche lassen sich unterscheiden : ein nördlicher (die Krim und die Gegend von Krasnodar), ein südwestlicher und ein östlicher. Innerhalb der Art wurde eine deutliche allopatrische Differenzierung festgestellt, die aber nicht mit einer entsprechenden Variation der männlichen Genitalien verbunden ist. Introduction The contrasting wing pattern is typical for almost all of the approx. 70 species of the Palaearctic genus Micropterix Hübner [1825] (HEATH, 1987). Wing pattern characteristics are widely used in determination keys (Razowskı, 1975; ZAGULAJEV, 1978; Kozıov, 1988; 1989; 1990a ; WHITEBREAD, 1992), and they are of critical importance for the identification of females, whose genitalia are very poor in specific characters. However, variation of wing pattern characteristics has not been studied in this genus and the absence of knowledge of the extent of interpopulation and geographical variation has sometimes caused taxonomic problems. The small (about 8-10 mm wing expanse) day-active irridescent moth Micropterix maschukella Alpheraky is widely distributed and very abundant in the Crimea and Caucasus. In Eastern Georgia the moths emerge at the beginning of May in the valleys ; at the altitudes 1500- 1700 m the last specimens were observed in late July. The moths feed on the pollen of several plant species, usually on elder (Sambucus nigra L.) and Philadelphus caucasicus Koehne. Sometimes they also visit flowers of Rubus spp. and Rosa spp. (pers. obs.). The investigation of wing pattern variation has been prompted by the description of a new species, Micropterix maritimella (Zagulajev, 1983) based on females originating from the population of M. maschukella in Gantiadi, Abkhasia, which I had studied for some years. Material and methods The study consisted of two parts : intrapopulation variation was investi- gated in Lagodekhi Natural Reserve (Georgia, formerly the U.S.S.R. ; 41°50’ N, 46°20’ E) ; geographical variation was studied from specimens 46 collected by the author and those kept in the Zoological Institute, St. Petersburg, Russia. Moths were sampled from inflorescences of host plants by net and im- mediately anaesthetised by chloroform. Each sample was characterized by frequencies of moths with different wing pattern (see Figs 1-5) ; males and females were recorded separately. In total, about 5,500 moths were thus investigated. Samples were compared by chi-square test or, if the sample size was very small, by the non-parametric lambda criterion. Diversity (u) was calculated according to ZHIVOTOVSKY (1982) : u = (yp, where p; is the frequency of the ith type of wing pattern (i = 1...5). The presence of geographical variation was tested by G-statistic for hetero- geneity of proportions (GABRIEL & SOKAL, 1969). Pairwise similarity Ry = LiVPixPit based on the ratio of frequencies (p;) of all the wing pattern types (1) in populations under comparison (k and |) (ZHIvotovsky, 1982) was calculated for all samples involved in the study ; similarity matrix was clustered on the base of mean arithmetic unweighed estimations of the similarity between clades. Results Wing pattern variation The general appearance of the golden pattern in M. maschukella includes two bands (basal and medial) and a subapical spot, sharply distinguished from the cupreous-brownish background. Five discrete types of forewing pattern were found. The first type has a large, almost rectangular subapical gold spot laying along the costal margin of the wing (Fig. 1). The second type differs from the first by having a small dark spot within this gold spot (Fig. 2). In both the third and fourth type there are two spots (small costal and large subapical) on the costal edge. These two types differ in the form of the subapical spot, which has its maximum width either at the costal margin (type 3, Fig. 3), or towards the centre of the wing (type 4, Fig. 4). The 5th type differs from the 4th due to the absence of the costal spot ; the large subapical spot is usually not connected to the costal edge of the wing (Fig. 5), although there are some exceptions. 47 Figs 1-5. The five types (numbers 1-5) of forewing pattern of M. maschukella. The two bands, although variable in form and width, did not show any clearly recognizable types. The right and left wings of the moth usually have the same type of wing pattern. However, 30.6% of specimens collected in Lagodekhi 1989 and 28.7% in 1990 were asymmetrical. But if the pattern of the right and left wing varies independently, the expected number of asym- metrical moths would be significantly (about 2 times) higher than observed (in 1989 : expected 64.0%, G = 799.1, df = 1, P < 0.0001 ; in 1990 : expected 56.9%, G = 291.9, df = 1, P< 0.0001). In spite of the high percentage of asymmetrical specimens, some genetic background of wing pattern types is assumed. But even if the variation is phenotypic only, it does not affect the conclusions of the present study. 48 1. Krasnolesye 2. Jalta 4. Alushta 6. Crimsk — 3. Gursuf 5. Staryi Crim 7.

Dendrogram based on the similarity between samples of M. maschukella in wing pattern frequency. In spite of the very low (about 10%) proportion of males in samples obtained from the inflorescences of elder in Lagodekhi, I succeeded in obtaining samples of 15-25 males from six local populations ; dif- ferences between sexes appeared to be non-significant (lambda = 0.04- 1.10). Differences between samples obtained in Lagodekhi in 1989 and 1990 from the same local populations were also not significant. Thus, I concluded that the frequencies of wing pattern types are relatively stable in time, and therefore the samples collected in different years can be compared when studying geographical variation. To increase the sample size, males and females were pooled when counting wing pattern frequencies. Geographical variation The 15 localities in the Crimea and Caucasus, significantly heterogeneous in wing pattern frequencies (n = 5242, G = 1383.6, df = 52, P < 0.0001), were included in the analysis. Clustering of the similarity matrix showed that the phenetic resemblances of samples correspond in general to their spatial proximities (Fig. 6). Three geographically consistent units were distinguished : northern (Crimea and Krasnodar district), south- western and eastern (Fig. 7). 49 20 0 1; 35% t | morphs Nalchik Er / rail / 13 e NZ +4 14 SukhumiX_12 ‚Mo TE 0 100 km Be Ser aC / Fig. 7.

Contours correspond to the clusters identified in Fig. 6. Groups of population : A — northern ; B — eastern ; C — south-western. Samples from the northern group demonstrated the lowest observed intrapopulation diversity (coefficient of diversity u < 2.5) ; about 90% of individuals belonged to the fourth type of wing pattern. This group was heterogeneous (n = 416, G = 59.4, df = 28, P < 0.0005) because of the most southern sample (from Gantiadi), which had an intermediate ratio of wing pattern types. If this sample is excluded from the consi- deration, the northern group becomes homogeneous in relation to wing pattern frequencies (n = 374, G = 28.3, df = 24, P< 0.251). Both the south-western and eastern groups are significantly hetero- geneous (n = 126, G = 30.1, df = 8, P < 0.0005, and n = 4700, G = 168.2, df = 12, P < 0.0001, respectively), and more diverse than the northern one (u = 3.5-4.5). In the south-western group the pattern number five was most abundant, in contrast to the eastern group where the second and fourth types had highest frequencies. The small number of localities being compared did not allow investigation of the geo- graphical variation of wing pattern within these groups. 50 Discussion Like leaf miners of the family Nepticulidae (MENKEN, 1990), M. maschu- kella bear characteristics which appear to facilitate rapid speciation : they occur in small isolated populations, the detritophagous cater- pillars and pollen-eating adults have only a few (if any) competitors, and their food resources are highly predictable. But, in contrast to sympatric speciation in Nepticulidae and Yponomeutidae (MENKEN, 1990 ; MENKEN et al., 1992), Micropterigidae demonstrate mostly geo- graphical (allopatric) differentiation. No differences in genitalic structure were found between males of M. maschukella with different wing patterns, or between local populations in Lagodekhi area and between populations from different geographical groups (Kozıov, 1990b and unpublished data). According to the re- cognition concept of species argued by PATERSON (1985), this may be due to visual recognition of the opposite sex in this moth species. In this respect M. maschukella is similar to butterflies, which often de- monstrate strict interspecific differentiation in wing pattern features, while male genitalia are quite similar, i.e. in the genus Erebia Dalm. (WARREN, 1936). Thus, the data obtained showed clear allopatric differentiation within the species, which, however, demonstrated no corresponding variation in male genitalia structure. It is possible that a complex of subspecies or even sibling species may exist under the name Micropterix maschu- kella, but at the present level of knowledge the differentiation in wing pattern is not sufficient to ascribe a taxonomic rank to geographically separated populations. | Acknowledgements I am very grateful to V.

Zusammenfassung Pharmacis claudiae sp. n. wird aus den italienischen Alpen (Aosta, Valtour- nenche) anhand einer Serie von männlichen Faltern beschrieben. Die Art unterscheidet sich sowohl habituell als auch genitalmorphologisch von den verwandten Taxa Ph. bertrandi (Le Cerf) und Ph. anselminae (Teobaldelli).

Einleitung Die Entdeckung einer bisher unbekannten Lepidopteren-Spezies in Mitteleuropa ist in heutiger Zeit ein seltenes Ereignis. Nach selbstkri- tischer Beurteilung der vorliegenden Fakten, dem Vergleich von Serien 53 von Genitalpräparaten und nach Einbeziehung genealogischer Über- legungen halten die Verfasser die Aufstellung eines neuen Taxons im Artrang für gerechtfertigt. Es ist wohl daher auch vertretbar, über die nüchterne wissenschaftliche Dokumentation hinaus eine kurze Beschrei- bung der Entdeckung des neuen Taxons beizufügen. Die Entdeckungsgeschichte von Pharmacis claudiae (P. M. Kristal) Am 28. Juli 1992 unternahmen wir (Claudia Kuon, Norbert Hirneisen und Philipp M. Kristal) während unseres Aufenthalts im Aosta-Tal (Italien) eine Tagestour zum Monte Cervinio (Matterhorn) am Ende des Valtournenche. Von der Talstation in Breuil-Cervinia fuhren wir mit der Seilbahn zum Giomein, also zur ersten Station auf ca. 2100 m Höhe. Von dort streiften wir durch das Gelände und fanden neben vielen hochalpinen Tagfalterarten auch einen Wurzelbohrer. Nach an- strengender Jagd auf den in unruhigem Zickzackflug über die alpinen Matten fliegenden Falter wurde diese Pharmacis “carna” von Norbert Hirneisen zur Präparation und Artbestimmung an Philipp Kristal über- geben, der diese “etwas dunkle fusconebulosa” gerne übernahm, da ihm weder die eine noch die andere Art aus seinen 12 Aufenthalten im Aosta-Tal bekannt war. Nach unserem Abstieg stand für uns fest, daß wir am Abend in der Nähe, “irgendwo über 2000 m” Lichtfang betreiben wollten. Da Philipp Kristal durch seine jahrelange Tätigkeit für das naturwissenschaftliche Museum in St. Pierre, Aosta-Tal, eine Genehmigung zum Befahren gesperrter Wege im gesamten Tal besaß, war nur das Problem des An- fahrens eines Leuchtplatzes gegeben. Erfahrungsgemäß erweisen sich auf der Karte verzeichnete Wege oftmals als nur für allradgetriebene Fahrzeuge befahrbar, so daß wir erst nach mehreren Fehlversuchen schließlich einen schönen Platz oberhalb von Antey-Saint-André bei Telınaud auf ca. 2200 m Höhe fanden. Das Terrain dort war spärlich bewachsen und auf den wenigen üppiger bewachsenen Matten grasten die Rinder der nahen Alpe. Nur noch einzelne Lärchen und Föhren umgaben uns, wir befanden uns dort offensichtlich direkt an der Waldgrenze. Dieser Platz erinnerte mich sehr stark an die mir bekannten Fundorte von Pharmacis anselminae im Val di Valeille und im Champorcher-Tal, da auch dort eine relativ starke Beweidung der Ph. anselminae-Biotope stattfindet. Diese Be- weidung scheint den Wurzelbohrern offensichtlich nicht zu schaden, wahrscheinlich ist dieser Umstand für die Ph. anselminae-Populationen sogar förderlich, wenn nicht sogar überlebenswichtig. 54 Nachdem uns Claudia Kuon trotz größter Schnakenplage ein Abend- essen in der “Feldküche” gezaubert hatte, konnten wir gut gestärkt mit dem Aufschlagen unserer beiden Leuchttürme beginnen, die wir mit einer Distanz von ca. 150 m errichteten. Der Anflug war, durch einen vom Tal aufsteigenden Wind begünstigt, sehr gut und wir hatten alle Hände voll zu tun, um alle anfliegenden Arten qualitativ und — soweit möglich — auch quantitativ zu erfasen. Gegen 1 Uhr Sommerzeit begab sıch jeder noch einmal zu seinem Turm, um nach einem letzt- maligen Absuchen des Leuchtplatzes mit dem Abbau zu beginnen. Uns fielen sofort die erst jetzt in Anzahl anfliegenden Wurzelbohrer auf, die wegen ihrer Größe, der sehr dunklen, fast schwarzen Grundfarbe und der grellweißen Zeichnung nicht sofort einer uns bekannten Art zuzuordnen waren. Durch die Distanz zwischen unseren Leuchttürmen konnten wir uns nicht sofort verständigen, und erst vor der Abfahrt konnten wir uns über diesen Bohrer unterhalten. Da Norbert Hirneisen nur ein Belegtier mitgenommen hatte, erwies es sıch als vorteilhaft, daß Philipp Kristal im Hinblick auf die Lokalsammlung des Museums in St. Pierre zwölf Tiere im Fangglas hatte, so daß genügend Anschauungs- material vorhanden war. Wir saßen in dieser Nacht noch lange über dieser Hepialide, die nach den Abbildungen bei FORSTER & WOHLFAHRT (1960) keiner uns bekannten Art zuzuordnen war. Überdies fiel uns auf, daß nach den Angaben dort Pharmacis carna und Ph. fusconebulosa ebenfalls ausscheiden müßten, da carna erst gegen Morgen zum Licht kommt, fusconebulosa jedoch in der späten Abenddämmerung fliegt. Aus eigener Erfahrung wußten wir, daß anselminae tagaktıv ist. “Unser” Bohrer jedoch kam ziemlich genau kurz nach 24 Uhr MEZ zum Licht. Da die Zeit des Paarungsflugs in der Regel genetisch festgelegt ist, kamen wir überein, daß wir uns diesen Bohrer doch noch näher ansehen müßten, denn es sei nicht auszuschließen, daß wir eine weitere, im Aosta-Tal endemische Art vor uns hätten, nachdem der Endemit Pharmacis anselminae auch erst vor ca. 15 Jahren von Teobaldelli im Aosta-Tal entdeckt worden war. Wir opferten unsere restliche Urlaubszeit diesem Unterfangen und konnten in drei Nächten noch weitere 6 Tiere am Licht erbeuten. Die Nachsuche nach Puppen oder Weibchen bei Tage, wie bei anselminae schon erfolgreich praktiziert, blieb jedoch in diesem Falle ohne greif- bares Ergebnis. Beim Anfertigen der Genitalpräparate stellte sich her- aus, daß wir, wie vermutet, nur männliche Falter am Licht erbeutet hatten und daß das Tier von oberhalb Breuil di Cervinio zur gleichen Art gehörte wie die Tiere von Antey-Saint-André. 55 Pharmacis claudiae Kristal & Hirneisen sp. n.

Im männlichen Genital- apparat unterscheidet sich claudiae von beiden Arten durch die sehr langen, schmalen Valven (bei bertrandi und anselminae wesentlich kürzer, nahezu erdnußförmig) und durch die U-förmige Einbuchtung zwischen den triangulären Vinvulumfortsätzen, von bertrandi außerdem durch das Fehlen der sternförmigen Sklerotisierung an der oberen medialen Spitze der Pseudoteguminalplatte und durch die unterschied- liche Form des ventralen Randes der Juxta. Ph. claudiae ist nachtaktiv, Ph. anselminae tagaktiv. WEIBCHEN : noch unbekannt. Die nahe Verwandtschaft zu den Arten mit brachypteren Weibchen, die (soweit bisher bekannt) stark einge- schränkte, endemische Verbreitung sowie die Tatsache, daß alle am Licht anfliegenden Tiere Männchen waren, deuten darauf hin, daß es sich auch bei Ph. claudiae um eine im weiblichen Geschlecht kurz- flügelige Art handeln könnte. AKTIVITÄTSPHASE : Die Aktivitätsphase der Männchen fällt ziemlich genau auf die Zeit zwischen 0 und 1 h MEZ. Ein einzelnes, wohl auf- 58 Abb. 4, 5.

Es ist zu vermuten, daß Ph. claudiae eine ähnlich kurze Flugzeit hat, wie sie für Ph. bertrandi anhand der vorliegenden Daten zu vermuten ist und für Ph. anselminae beobachtet wurde. Eine kurze Flugzeit von einer Woche bei sehr lokaler Verbreitung erklärt sowohl die späte Entdeckung der Arten Ph. claudiae und Ph. anselminae als auch das spärlich vor- handene Material bei Ph. bertrandi. Es sollte an dieser Stelle auch die von DANIEL (1950) für Ph. carna aufgestellte Vermutung einer nur eintägigen Lebendauer der Männchen in die Überlegungen zur Biolo- 60 gie der Arten einfließen, obwohl gerade Ph. carna eine ausgedehnte Flugzeit hat. DERIVATIO NOMINIS : Die Namensgebung erfolgt zu Ehren unserer be- zaubernden Kollegin, Frau Claudia Kuon, die uns in den kalten Hoch- gebirgsnächten immer begleitete, verpflegte und die erschöpften Ento- mologen im Morgengrauen sicher nach Hause fuhr. Sie war trotz des mehr als 60 km weiten Anfahrtsweges durchs Gebirge und der dort oben herrschenden Schnakenplage stets gut aufgelegt und half uns somit in nicht zu unterschätzender Weise.

Vorderflügellänge 17 mm (n= 1). Die Zeichnungselemente sind ähnlich wie bei Ph. carna an- gelegt. Die Grundfärbung ist etwas heller, die weißen Flecken sind weit spärlicher vorhanden. Zwei bis drei kleine Fleckchen bilden, deutlicher als bei den verwandten Arten, eine weiße Basalstrieme. Die kettenartige, aus hellbraun umrandeten runden Fleckchen bestehende Binde ent- springt hier ebenfalls im Analwinkel des Vorderflügels, zieht gerade verlaufend zur Costa und trifft ca. 1 mm vor dem Apex auf die Costa. Die Fransen aller Flügel sind einfarbig dunkelbraun. MANNLICHER GENITALAPPARAT (Abb. 12): Valven gebogen, kürzer als bei Ph. claudiae, in der Mitte etwas eingeschnürt, dadurch in der Form an eine Erdnuß erinnernd. Ventraler Rand des Vinculum regel- mäßiger gerundet als bei Ph. claudiae und Ph. anselminae. Einbuchtung zwischen den triangulären Vinculumfortsätzen grob U-förmig bzw. (am ventralen Rand der stark sklerotisierten Zone) abgerundet W-förmig (vgl. auch TEOBALDELLI, 1977, Abb. 3). WEIBCHEN : Die Weibchen sind brachypter. AKTIVITÄTSPHASE : Den Verfassern sind keine Angaben bekannt. VERBREITUNG : Französische Alpen, Alpes-Maritimes (Guil-Tal) und Hautes-Alpes (Abries). Das vorliegende Belegstück ist mit “Chamonix” bezettelt, wobei nicht eindeutig klar ist, ob es sich, wie auf dem Etikett angegeben, um einen Ort in den Hautes-Alpes oder vielleicht um das 61 bekannte Chamonix am Mont Blanc (Haute-Savoie) handelt, wodurch das bekannte Verbreitungsareal der Art beträchtlich erweitert würde. VERTIKALVERBREITUNG : 1900-2400 m (FREINA & Wirt, 1990). BıoToPr : Alpine Kurzrasen (FREINA & Witt, 1990). FLuGzEIT : Zweite Julihälfte bis August (FREINA & Witt, 1990). Vor- liegende Funddaten vom 17. Juli bis 20. Juli.

Hasitus (Abb. 4) : Spannweite 32-33,5 mm, © 32,6 mm (n = 6) ; TEo- BALDELLI (1977) und FREINA & Witt (1990) : 28-33 mm. Vorderflügel- länge 14,5-16,5 mm, © 15,1 mm (n = 18). Im Habitus erscheinen die Tiere untereinander recht einheitlich. Die Grundfärbung aller Flügel ist ein schwärzliches Dunkelbraun, in welchem auf den Vorderflügeln unregelmäßige, nicht scharf begrenzte, hellere, weißlichgraue Fleckchen stehen. Hellbraune Zeichnungselemente als Umrandung der helleren Flecken wie bei den anderen Arten der Gruppe fehlen gänzlich. Die Hinterflügel sind einfarbig dunkelbraun ohne Einmischungen, die Fran- sen aller Flügel sind ebenfalls einfarbig dunkelbraun. MANNLICHER GENITALAPPARAT (Abb. 13-18) : Valven gebogen, kürzer als bei Ph. claudiae, in der Mitte etwas eingeschnürt, dadurch in der Form an eine Erdnuß erinnernd. Ventraler Rand des Vinculum regel- mäßiger gerundet als bei Ph. claudiae aber kantiger als bei Ph. ber- trandi. Vinculum zwischen den triangulären Fortsätzen ın der Regel V-förmig eingebuchtet (zwei der untersuchten Männchen zeigen eine abweichende U-Form, Abb. 17-18) und ventral weniger stark ausge- buchtet. Vinculum stets mit fleckenartigen Sklerotisierungen entlang der Ränder (nur in Abb. 13 zeichnerisch dargestellt, aber in allen Präparaten vorhanden), die bei den anderen Arten fehlen. Pseudo- teguminalplatte insgesamt ähnlich wie bei Ph. claudiae, das obere mediale Ende aber breit abgerundet, nur schwach sklerotisiert. Ventraler Rand der Juxta flach konkav gebogen. In der Vinculumform besteht eine gewisse Variation ; ferner zeigt ein Präparat (hier nicht abgebildet) im Vinculumbereich eine pathologische Deformation. Möglicherweise handelt es sich dabei um Defekte als Folge der Isolation (Inzucht). Wir nutzen die Gelegenheit, die Genitalien von Pharmacis anselminae in Serie abzubilden.

Pharmacis carna (|Denis & Schiffermüller], 1775) UNTERSUCHTES MATERIAL: 6 4, Italia, Trento/ Brescia, Monte Tremalzo, 1800 m, Daten vom 27.7.-3.8.1974, leg. Ströhle, coll. Kristal. Hasitus : Spannweite 32-37 mm, © 34,4 mm (n = 6) ; FREINA & Witt (1990) : && 25-34 mm, 99 32-44 mm. Vorderflügellänge 15,5-17 mm, © 16,3 mm (n = 6). Die Grundfarbe der Flügel ist ein dunkleres Mittel- braun, in dem auf den Vorderfliigeln unregelmäßige helle Zeichnungs- elemente stehen, die wiederum hellockerbraun umrandet sind. Vom Analwinkel ausgehend läuft eine aus ockerfarbenen Ringen bestehende Fleckenreihe direkt in den Apex des Vorderflügels. Die Fransen der Vorderflügel sind kaum erkennbar gescheckt, fast einfarbig mittelbraun, die Hinterflügelfransen sind am Grunde einfarbig dunkelbraun, an den Spitzen etwas heller gefärbt. () TEOBALDELLI (1977) machte verschiedene Aussagen. Die Daten der Typenserie lauten “bei 2000 m” bis “2500 m” ; im Text finden sich außerdem die Angaben “in Höhen zwischen 1800 und 2500 m” (S. 38) sowie “zwischen 1900 und 2200 m ... bei 2500 m” (S. 41). 64 Abb. 13-18.

Der kleine, schneiden- artige, sklerotisierte Fortsatz in der Mitte des medialen Randes der Pseudoteguminalplatte, der bei den Vergleichsarten vorhanden ist, fehlt bei Ph. carna völlig. WEIBCHEN : Die Weibchen haben voll entwickelte Flügel. AKTIVITATSPHASE : “Hepialus carna hat ein erstes Flugintervall im Morgengrauen, um welche Zeit einzelne dd — so ziemlich als letzte Falter — am Licht erscheinen. ... Die eigentliche Flugzeit setzt jedoch erst um 7.30 Uhr ein... Der Falter fliegt, so lange es ziemlich kühl ist, in der Sonne, etwa von 8.30 Uhr ab nur mehr an schattigen Stellen... Der Flug dauert bis gegen 12 Uhr...” (DANIEL, 1950). Diese Beobach- tungen beziehen sich auf Beobachtungen zwischen 1800 und 2200 m auf apinen Rasen an den Südhängen des Watzmannstockes in den Berchtesgadner Alpen. In tieferen Lagen konnte DANIEL (1950) Ph. carna nur am Licht nachweisen. VERBREITUNG: In Europa in den Alpen und den osteuropäischen Ge- birgen. Ob sich die Angaben vom Ural und aus den asiatischen Ge- birgen sowie aus den subarktischen Regionen Asiens wirklich alle auf Ph. carna beziehen, bedarf noch der Klärung, ebenso die bis heute in der Literatur vertretene Meldung aus der ungarischen Tiefebene (PFITZNER, 1912 ; FREINA & Wirt, 1990). VERTIKALVERBREITUNG : In den Alpen von der montanen bis zur alpinen Höhenstufe. DANIEL (1950) gibt für die Berchtesgadener Alpen Funde zwischen 1150 und 2200 m mit einem Maximum zwischen 1700 und 2000 m an. Die bei FREINA & Witt (1990) abgebildeten alpınen Belegstücke weisen Funddaten zwischen 1300 und 1800 m auf. Ein Tier aus den Karpaten wırd mit 540 m angegeben. 66 pes Abb. 21.

Brorop : Montane und subalpine Populationen finden sich im Bereich üppigster Vegetation (DANIEL, 1950). FREINA & Wirr (1990) verweisen auf kräuterreiche, hanglagige Wiesenmatten. Die alpinen Populationen bewohnen wie die verwandten Arten alpine Rasen. FrLugzeiır : Ende Juni bis in den späten August (FREINA & Wirt, 1990). Diskussion (A. Steiner) Ohne eine Gesamtrevision der Gattung Pharmacis lassen sich keine endgültigen Aussagen über die phylogenetische Stellung der einzelnen Taxa machen. Ph. bertrandi und Ph. anselminae stehen sich ungeachtet der klaren habituellen Unterschiede genitalmorphologisch sehr nahe ; möglicherweise sind sie Schwestertaxa. Es steht zu vermuten, daß die Brachypterie im weiblichen Geschlecht in der Gattung Pharmacis nur einmal aufgetreten ist, so daß alle Arten mit kurzflügeligen Weibchen ein Monophylum bilden und das Merkmal selbst eine Synapomorphie dieser Gruppe darstellt (als weitere Synapomorphien kommen die Merkmale “ventraler Rand des Vinculum ausgebuchtet” und “schneiden- artiger sklerotisierter Fortsatz am medialen Rand der Pseudoteguminal- platte” in Frage). Der weitgehende Verlust der Lokomotionsfähigkeit der weiblichen Imago durch Brachypterie ist ein schwerwiegender Schritt im Evolu- tionsgeschehen einer Art, der gut begründet sein muß. Die Brachypterie kann durch endogene Faktoren bedingt sein: die Weibchen einiger 67 > Een E 39 & © 37 = QO anselminae = 35 = © bertrandi © 33 Q 3 X) © claudiae 31 29 Vorderflügellänge in [mm] Abb. 22. Verhältnis von Vorderflügellänge und Spannweite. Lasiocampiden und Arctiiden, die im Imaginalstadium keine Nahrung aufnehmen können und somit als Adulte nur eine kurze Lebensdauer haben, müssen bereits beim Schlupf den Großteil ihrer Eier fertig entwickelt haben. Durch das schwere Abdomen behindert sind solche Weibchen oft ausgesprochen flugtrage und bewegen sich fast nur zu Fuß, so daß eine Flügelreduktion hier nur die Einsparung ohnehin ungenutzter Körperteile bedeutet. Als Ausgleich für die fehlende Vagi- litat der Weibchen haben dann meist die Raupen Ausbreitungspotentiale erschlossen, so bei Orgyia die Windverdriftung der L,-Raupe, die dafür mit langen Haarbüscheln ausgestattet ist. Brachypterie kann aber auch eine Reaktion auf exogene Faktoren sein, etwa bei Arten, die in ungünstigen Jahreszeiten fliegen (zahlreiche Herbst-, Winter- und Frühjahrsarten, besonders unter den Geometridae) oder ın Regionen leben, in denen die Flugfähigkeit ein Nachteil sein kann, so im Falle von Endemiten auf kleinen Inseln in Gebieten mit starken Winden, die Gefahr laufen, aufs Meer verdriftet zu werden (z. B. Agrotis cunhaensis). Im Hochgebirge hat die Evolution der Bra- chypterie genau die selben Ursachen : Imagines von Arten, die die Glazialzeiten auf inneralpinen Nunatakkern — also ebenfalls in isolierter Lage — überdauerten, waren beim Verdriften von ihrer Refugiumsinsel auf die umliegenden Gletscher zum Tode verurteilt. Geringe Flugak- tivität und in der Folge Flügelreduktion erwies sich in dieser Situation als Selektionsvorteil und wurde von einer ganzen Reihe von Arten genutzt, sowohl in den “massifs de refuge” der Hochgebirge als auch 68 Abb. 23. Habitat von Pharmacis claudiae sp. n. bei Antey-St.-Andre (Aosta). im borealen Bereich (Agrotis fatidica, Xestia (Schoyenia) spp., Elophos spp., Pharmacis spp. u. a.). Doch was in den Glazialia eine Überlebens- strategie war, erweist sich heute als Hindernis für die Dispersion dieser Arten, so daß bei vielen von ihnen davon ausgegangen werden kann, daß ihr rezentes Areal sich seit dem letzten Glazial nur wenig erweitert hat. Ein auffallend geringes Dispersionspotential weisen auch manche flugfähigen Arten auf, z. B. einige Arten der Genera Erebia, Psodos und der Tribus Gnophini. (Daß die Flügelreduktion meist nur das weib- liche Geschlecht betrifft, liegt daran, daß eine rasche Geschlechterfindung 69 nur dann gewährleistet ist, wenn der suchende Partner geflügelt ist, und daß andererseits die Population den Verlust von Männchen eher verkraften kann, denn auch wenige überlebende Männchen sind in der Lage, alle vorhandenen Weibchen zu begatten, während jeder Verlust eines Weibchens den Verlust ihres Eivorrats und somit ihrer gesamten potentiellen Nachkommenschaft bedeutet.) Die Gruppe der gebirgsbewohnenden Pharmacis-Arten mit brachy- pteren Weibchen wird ım folgenden Text nach dem zuerst beschriebenen alpinen Vertreter als bertrandi-Artengruppe bezeichnet, umfaßt aber auch Ph. pyrenaicus (Donzel, 1838) und eventuell einen weiteren Ver- treter im Kaukasus. Möglicherweise existieren noch unentdeckte oder bisher mit Ph. carna verwechselte Taxa in asiatischen Hochgebirgen. Pharmacis carna (eventuell einschließlich nahe verwandter geflügelter Arten) stellt vermutlich die Schwestergruppe der Pharmacis bertrandi- Gruppe dar. Im Laufe mehrerer Eiszeiten wurde das Areal der Phar- macis bertrandi-Gruppe mehrfach zersplittert und zweifellos sind auch manche Populationen, die den Vergletscherungen nicht ausweichen konnten, ausgestorben. Wann sich im alpinen Raum die Aufspaltung in die Arten Ph. bertrandi, Ph. anselminae und Ph. claudiae vollzogen hat, läßt sich beim heutigen Kenntnisstand nur schwer beurteilen ; die deutlichen Unterschiede in Habitus und Genitalmorphologie und die stark reliktäre Verbreitung lassen jedenfalls eine Aufspaltung schon vor dem Würmglazial vermuten. Die rezente Situation stellt sich folgender- maßen dar : Es existieren eine Reihe von isolierten Populationen im Be- reich der Südwestalpen, wobei an jeder einzelnen Fundstelle nur je eines dieser Taxa nachgewiesen ist. Über ihr aktuelles Expansionspotential wissen wir wenig, die Weibchen sind aber flugunfähig und können wohl auch nicht von den Männchen transportiert werden ; als einzige Me- thode der Arealexpansion bleibt die Fortbewegung im Raupenstadium, und die dürfte bei terrestrischen Raupen, die nicht die Möglichkeit haben, sich im Jugendstadium am Faden treiben zu lassen, gering sein. Es sieht also so aus, als ob die einzelnen Populationen noch immer in etwa die Regionen bewohnen, die ihnen während des Höhepunkts des letzten Glazials als Refugien gedient haben. Zur Beurteilung der Frage, ob sich diese Populationen zu Arten differenziert haben, stehen derzeit folgende Informationen zur Verfügung: Habitus und Genital- morphologie der Imagines (bei Ph. claudiae nur der Männchen), zirka- dianer Aktivitätsrhythmus (nicht für alle Populationen), Flugzeit, Bio- tope und Vertikalverbreitung. Die zwei letzten Punkte sind beı allen Populationen so ähnlich, daß zur Beantwortung der Frage nur Mor- phologie, Anatomie, Flugzeit und tageszeitliche Aktivität bleiben. Bei den meisten Hepialidae besteht in großen und zusammenhängenden 70 Populationen in der Regel eine große Variation in der Flügelzeichnung und -färbung. Dies gilt für Ph. fusconebulosa (DE GEER, 1778) und darf wohl auch für den gemeinsamen Vorfahren der Ph. bertrandi-Arten- gruppe vorausgesetzt werden. Wenn bei einem solchen Vorfahren Eng- pässe (bottleneck-Situationen) in mehreren disjunkten Reliktpopula- tionen auftreten, wie dies während der Vereisungs- und Eisrückzugs- phasen des Pleistozäns mehrfach eingetreten sein muß, dann darf ge- radezu damit gerechnet werden, daß sich die einzelnen disjunkten Teil- populationen bezüglich des Merkmals Flügelzeichnung stark ausein- anderentwickelten, so daß selbst nahestehende Taxa (z. B. Schwester- taxa) nicht unbedingt durch ähnliche Flügelzeichnung ausgezeichnet sein müssen und daß die Flügelzeichnung alleine in einer solchen Gruppe kein verläßlicher Indikator für genealogische Verwandtschaft sein kann. Differenzen in der Genitalmorphologie und in der tageszeit- lichen Aktivität können hier eher zur Klärung verwandtschaftlicher Beziehungen herangezogen werden. Selbst in der Flugzeit scheinen sich Ph. anselminae und Ph. claudiae zu unterscheiden (wenn nicht sogar auszuschließen) : Ph. anselminae wurde nur bis zum 15.7., Ph. claudiae erst ab dem 28.7. nachgewiesen, wobei allerdings berücksichtigt werden muß, daß bisher für beide Arten nur wenige Phänologiedaten vorliegen. Bei den geographisch teils sehr eng benachbarten Taxa der Ph. ber- trandi-Gruppe bietet es sich an, durch Raupen- und Puppensuche oder Zucht einerseits die Präimaginalstadien kennenzulernen und deren Mor- phologie, Biologie und Ökologie zu vergleichen, andererseits virgine Weibchen zu erlangen und mit diesen in Biotopen der jeweils anderen Arten Anflugversuche durchzuführen, um das Vorhandensein (oder Fehlen) von Isolationsmechanismen durch Pheromoninkompatibilität, durch anatomische Differenzen in der Genitalmorphologie oder durch sich ausschließende zirkadiane Aktivitätsrhythmen nachzuweisen. Hier wie in ähnlich gelagerten Fällen öffnet sich ein weites Betätigungsfeld auch für den Amateur-Entomologen, der sich nicht auf das Anhäufen toter Imagines beschränken sollte, sondern — mit entsprechender wis- senschaftlicher Untermauerung — wertvolle Beiträge zur Kenntnis der Holomorphe und ihrer Autökologie liefern kann. Schließlich muß mit der Möglichkeit gerechnet werden, daß in den südwestlichen Alpen (besonders auf der entomofaunistisch wenig intensiv durchforschten italienischen Seite) weitere lokale Populationen von Vertretern der Ph. bertrandi-Artengruppe existieren, die noch ihrer Entdeckung harren. 7A Danksagung Wie danken Herrn Thomas Witt (München) für die Ausleihe eines Pharmacis bertrandi-Belegstücks und Herrn Wolfgang Ströhle (Weiden/Opf.) für die Überlassung einer Serie von Pharmacis carna.

Tribus Cyclophorini Diese Tribus enthält in Mitteleuropa nur die Gattung Cyclophora Hüb- ner, 1822, mit folgender Charakteristik : Mittelkleine (ca. 11-14 X 2,5-3,5 mm), ziemlich gleichförmige, in Ven- tralsicht charakteristisch keilförmige Spannerpuppen (Abb. 1), vorn am breitesten und stark abgestumpft. Thorakale Spiracularhöcker ecken- artig vorspringend. Von diesen läuft parallel zum Dorsalrand der Vor- derflügel je eine erhabene Kante. Auch zwischen Clypeus und Frons eine Kante (Abb. 1-2). Färbung fahl (sand-) gelb bis rot- oder grau- 74 bräunlich. Manche Arten weisen außerdem grüne Puppenformen auf. Körper oft gesprenkelt mit Fleckenzeichnungen am Clypeus, an der Vorderflügelbasis, am Thorax und Abdomen. Längs des kantenartigen Dorsalteiles der Vorderflügel oft ein dunkler Streifen, auch die Adern manchmal + verdunkelt. Puppen nur schwach glänzend. Skulptur mittel- grob bis mittelfein, wirr runzelig, zuweilen etwas höckerig, 1.-7. Ab- dominalsegment meist mit — scharfen Punktgrübchen (Abb. 18, 45). Labrum breit, abgerundet bis trapezförmig (Abb. 3, 7, 20). Labium ganz verdeckt. Genae oben beulenartig erhaben. Die Grenze zwischen Proboscis und Genae verläuft eher quer zur Längsachse der Puppe, die zwischen den Vorderbeinen und Antennae mehr schräg. Grenze der Vorderbeine mit den Antennae 4-5 X länger, die mit den Genae etwa 1,5-3 X kürzer als die Grenze zwischen den Vorderbeinen und Oculi (Abb. 4, 8). Vorderschenkel und Enden der Hinterbeine sicht- bar. Proboscis wenig, Vorderbeine deutlich kürzer als die Mittelbeine und Antennae, diese überragen die Vorderflügel nicht (Abb. 1). Basen der Antennae, Frons, der ziemlich gut differenzierte, schmale Vertex und das Pronotum befinden sich an der abgestumpften Frontalseite der Puppe (Abb. 2). Frontolateral (Spiracular-) Höcker des Mesono- tums manchmal mit komplizierten Einschnürungen, zuweilen lappig (Abb. 9, 43). Frontolaterale Ausläufer des Metanotums relatıv spitz (Abb. 19, 39). Thorakale Spiracula undeutlich. Hinterflügel schmal, bis etwa zum Caudalrand des 3. Abdominalsegmentes sichtbar. Spira- cula am 2. Abdominalsegment deutlich, am 3. Segment verdeckt, relativ groß, elliptisch, ihre Höfe breit (Abb. 2). Zwischen dem 9. und 10. Ab- dominalsegment, dorsal und lateral, gibt es weder eine Rinne, noch Einschnitte (Abb. 11, 12). Das 9. Segment ziemlich kurz, insbeson- dere an der Ventralseite. An der Dorsalseite trägt es V- oder trapez- förmige, zuweilen abgerundete Vertiefungen, die kantenartig gesäumt sind (Abb. 11, 12, 27, 31, 33). Analfeld deutlich, meist dreieckig, manch- mal längsgefurcht. Die Analnaht zuweilen mit erhabenen Lateralwällen (Abb. 17, 22). Kremaster + so lang wie basal breit, dorsoventral abgeplattet. In der Dorsalansicht ist er entweder zungenförmig, am Ende relativ spitz (Abb. 33) ; oder am Ende abgestumpft (Abb. 12), bzw. stumpf- oder rechtwinklig (Abb. 31, 42). Ventralseite oft mit Basalhöckern und einer größeren oder kleineren Basalvertiefung (Abb. 6, 17). Von den 4 Paaren der hakenartigen Kremasterborsten entspringt D1 dorsal vor dem Ende des Kremasters und ist kleiner als die übrigen. Diese etwa gleichgroß, dicht in einer Gruppe am Kremasterende konzentriert (Abb. 54). Sonst ist der Kremaster + gerunzelt bzw. gefurcht. 75 Abb. 11-24. 11 — Cyclophora pendularia ; 12-14 — C. albiocellaria ; 15-18 — C. annulata ; 19-23 — C. albipunctata ; 24 — C. puppillaria. 11, 12, 16, 23 — Abdomenende in Dorsal- ; 13, 17, 18 — in Ventralsicht ; 14, 18 — 5.

Die Puppe ruht oberirdisch an einem besponnenen Blatt der Futter- pilanze, mit Hilfe der Kremasterhäkchen und eines Gespinstgürtels “tagfalterartig” am Blatt befestigt. Die Überwinterung findet im abge- fallenen Laub bzw. in einer noch belaubten Baumkrone statt. Die Arten leben vorwiegend an Laubhölzern (nur C. suppunctaria an Kräutern) und sind in Mitteleuropa meist bivoltin (selten uni- bzw. trivoltin) ; die Puppen findet man im Sommer und von Herbst zum Frühling. Die einzelnen Arten bewohnen Laub- und Mischwälder, zuweilen die Waldsteppe. C. puppillaria ist als Wanderfalter bekannt.

Diskussion Die untersuchten Puppen der Tribus Cyclophorini mit der einzigen mitteleuropäischen Gattung Cyclophora bilden hinsichtlich ihres Baues eine geschlossene, wenig differenzierte Einheit. Auch die einzelnen, auf Grund ihrer bevorzugten Futterpflanzen gebildeten Gruppen — an Salicaceae (C. pendularia), Betulaceae (C. albipunctata), Fagaceae 85 (C. puppillaria, C. ruficiliaria, C. porata, C. quercimontaria, C. punc- taria, C. linearia), Aceraceae (C. albiocellaria, C. annulata), Asteraceae, Fabaceae u.a. (C. suppunctaria) unterscheiden sich puppenmorpho- logisch kaum voneinander. Die Cyclophora-Puppen weichen von den anderen der Familie Geo- metridae stark ab. Ihre Körperform ist der bei den Spannern wenig üblichen Verpuppungsweise an der Oberfäche der Blätter ihrer Nah- rungspflanzen angepaßt und weist dementsprechend weitgehende Adap- tationen auf. Sie entsprechen anderen, sich auf diese Weise verpup- penden (und sonst einander wenig verwandten) Schmetterlingsgruppen. Auffallend ist der lang vorgezogene Kremaster mit der Konzentrierung der hakenförmigen Haftborsten auf sein Caudalende. Eine sonst bei der Familie Geometridae wenig übliche, helle Färbung, nicht selten mit Zeichnungen, fast ohne Glanz, eckige Ausläufer am Vorderteil des Körpers, die Befestigung der Puppe an einem Blatt mittels Kremaster- häkchen und eines Gespinstgürtels erinnern an ähnliche Verhältnisse bei den Familien Papilionidae, Pieridae usw. Während die einzelnen Arten auch als Imagines relativ schwer zu bestimmen sind, ist ihre Unterscheidung anhand der Puppenmerkmale möglich und relativ ver- läßlich.

Adults and genitalia of both sexes are illustrated. The new species is most closely related to P Jatreillella Curtis and P nodosella (Bruand), from which it can be distinguished by the wing markings and genitalic cha- racters. Resume Description de Pancalia baldizzonella sp. n. d’Italie méridionale. Les adultes et les armures génitales des deux sexes de ce taxon sont figurées. Zusammenfassung Pancalia baldizzonella sp. n. wird aus Süditalien beschrieben. Die Imagines und die Genitalien beider Geschlechter werden abgebildet. Die neue Art steht P. latreillella Curtis und P nodosella (Bruand) am nächsten, von denen sie sich durch die Flügelzeichnung und Genitalmerkmale unterscheidet. Introduction Depuis la parution d’un article de GAEDIKE (1967) consacré aux espèces de Pancalia Stephens, 1829, ce genre et ses espèces ont été étudiés à plusieurs réprises (LERAUT, 1984 ; RrEDL, 1984 ; SINEV, 1985). Ces études ont permis d’expliquer la position systématique du genre en question et de confirmer, après deux révisions, l’existence de 9 espèces nomi- nales habitant uniquement la zone paléarctique, à savoir P gaedikei Sinev, 1985, P hexachrysa (Meyrick, 1935), P isshikii Matsumura, 1931, P. latreillella Curtis, 1830, P. leuwenhoekella (Linnaeus, 1761), P nodo- sella (Bruand, [1851]), 2 sichotella Christoph, 1882, P sinense Gaedike, 1967, P swetlanae Sinev, 1985. 87 Fig. 1-2. Pancalia baldizzonella sp. n. 1 — holotype (mâle) ; 2 — paratype (femelle) (phot. G. Baldizzone). Il m’a récemment été possible d’examiner les matériaux récoltés par le Dr. G. Baldizzone en Italie méridionale et de trouver parmi de nom- breux Cosmopterigidae une nouvelle espèce du genre Pancalia qui est donc le dixième taxon spécifique appartenant à ce genre. Pancalia baldizzonella sp. n. Ho.otype (Fig. 1) : Mâle, “Mt. Pollino, 1500 m, Lucania, Piano di Ruggio, 9. VII. 1991, G. Baldizzone leg.”, prép. gén. no. 1415/R. PARATYPE (Fig. 2) : Femelle, prép. gén. no. 1414/R. Portant la même étiquette. L’holotype et le paratype sont conservés dans la collection du Dr. G. Baldiz- zone à Asti. 88 Envergure de l’holotype : 15 mm ; du paratype : 14,5 mm. Tête, thorax, tegulae et palpes labiaux brun foncé, unicolores, brillants. Antennes brun foncé, unicolores chez le mâle et avec la partie subterminale du flagellum blanche chez la femelle (Fig. 1-2). Ailes antérieures foncées ; la base, l’apex, les bords antérieur et posté- rieur sont brun foncé, la partie centrale de l’aile est brun-jaunätre. Le dessin se compose d’une tache costale externe blanche et de tubercules d’écailles réfractives argentées. Le bord antérieur présente trois tubercules dont l’externe est réuni avec la tache costale blanche et l’interne, réuni avec le tubercule postérieur interne, forme avec celui-ci une écharpe transversale basale. Le second tubercule postérieur est rond, petit et situé plus près de la base de l’aile que le tubercule costal intermédiaire. Le troisième est allongé, enfin le quatrième, étroit, peu développé, est situé le long du bord postérieur de l’aile sous le tubercule costal externe et la tache costale blanche. Franges brun foncé. Ailes postérieures et leurs franges brun foncé. La forme des bandes du système de renforcement de la base de l’ab- domen (Fig. 3) est la même que chez P Jatreillella Curtis : la bande transversale est droite, mince, les bandes latérales du premier tergite sont également à peu près droites. ARMURE GÉNITALE MÂLE (Fig. 4-6) : Valves lobiformes, non arquées, leur bord ventral légèrement concave. Juxta développée en tant que deux bras de longeur inégale (Fig. 5), allongés et étroits. Aedoeagus arqué (Fig. 6) ; sa partie proximale possède une saillie ventrale très distincte. Terminaison de l’aedoeagus aiguë. ARMURE GÉNITALE FEMELLE (Fig. 9): Lamelle antévaginale à bords latéraux parallèles, son bord proximal convexe. Ostium bursae étroit, les deux signa peu distincts. Je nomme cette intéressante nouvelle espèce européenne en l’honneur de mon éminent collègue italien, distingué spécialiste des Lépidoptères Coleophoridae, le Dr. Giorgio Baldizzone (Asti). Commentaire P. baldizzonella sp. n. est la plus proche de deux espèces européennes, P latreillella Curtis et P nodosella (Bruand). Elle s’en distingue cepen- dant au premier coup d’ceil par le fond de la partie centrale des ailes antérieures qui est brun-jaunâtre tandis que chez les deux espèces men- tionnées ce fond est ferrugineux foncé. Le dessin des ailes antérieures ne présente aucun caractère particulier. Les différences les plus marquées concernent la forme des armures génitales. Chez le mâle, les deux bras 89 Figs 3-4.

Pancalia spp., armure génitale mâle : bras de la juxta (5, 7); aedoeagus (6, 8). 5, 6 — P baldizzonella sp. n. ; 7, 8 — P. nodosella (Bruand). de la juxta (Fig. 5) sont relativement étroits et allongés ; chez d’autres espèces de Pancalia, par example chez P nodosella (Bruand) (Fig. 7), ces sclérites sont moins allongés et nettement plus larges. En outre, parmı toutes les especes connues de Pancalia, P. baldizzonella sp. n. presente la saillie ventrale de l’aedoeagus la plus grande (Fig. 6). Cette saillie chez les autres, y compris P nodosella (Bruand) (Fig. 8), est plus petite et moins distincte. Chez la femelle, notre attention doit se porter sur la forme de la lamelle antévaginale, qui est bien caractéristique et diffère sensiblement de celles d’autres espèces de Pancalia. 90 Fig. 9.

August 1993 verstarb Eberhard Jäckh in seinen Haus in Hörmanshofen. Er saß in seinem Sessel, als er schnell und fast schmerzlos zur ewigen Ruhe kam. Er wurde am 5. Dezember 1902 in Kassel geboren, hat also den größten Teil dieses ausgehenden Jahrhunderts erlebt. Zur Zeit seiner Geburt regierte noch der Kaiser in Deutschland und der “Weltkrieg” war noch kein Begriff. Autos standen noch am Anfang der Entwicklung, Rundfunk und Fernsehen waren unbekannt, wie die meisten Geräte der heutigen Technik. Eberhard war das älteste von drei Geschwistern, Sohn von Dr. med. Alexander Jäckh, Chirurg und Frau Erna, geb. Hartdegen, einer talentierten Malerin. 93 Die Eltern starben beide früh. Schon während seiner Studienjahre im Internat entdeckte Eberhard jene Begeisterung für Insekten, die für sein ganzes Leben bestimmend wurde. Die Berufsausbildung begann er in Bremen, mit der Idee, als Schiffsingenieur die Welt kennenzulernen. Nach Abschluß der Ausbildung am Technikum erwies sich jedoch, daß seine immer größer werdende Passion für die Entomologie nicht mit wochenlangen Fahrten auf hoher See zu ver- einbaren waren. So wechselte er über zum Flugzeugbau. Viele Jahre arbeitete er bei der Firma Focke Wulf in Bremen, was ihm die direkte Teilnahme am ganz Europa zerstörenden Krieg ersparte. Auch seine Wohnung in Bremen wurde zerstört. 1937 heiratete er Adele Lakmann. 1940 wurde ein Sohn, auch Eberhard benannt, geboren, der jetzt mit seiner Familie in den USA lebt. Sein Interesse an der Entomologie vertiefte sich. Er konnte seine Kenntnisse erweitern, dank der Zusammenarbeit mit einigen bekannten Insektenforschern. Besonders Prof. E. M. Hering, Berlin, wurde sein Lehrmeister und Freund. Vor allem widmete er sich den Microlepidopteren. Äußerst aktiv beteiligte er sich am Wiederaufbau des Entomologischen Vereines Bremen. Das Bremer Überseemuseum engagierte ihn zunächst als freien Mitarbeiter. Das Hobby wurde zum Beruf, als ihm gleich nach dem Krieg 1945 die Leitung der Entomo- logischen Abteilung des Museums übertragen wurde, die er bis zur Pensio- nierung behielt (1967). Seine Frau Adele verstarb früh in Jahre 1960. Sieben Jahre später heiratete er Ingeborg Hoyer, die ihn als liebevolle Gefährtin bis zu seinem letzten Atem- zuge begleitete. 1974 zogen beide von Bremen zum Alpenrand und erwarben ein Haus in Hörmanshofen im Allgäu. Das Ehepaar ist viel gereist, vor allem nach Italien. Beide sprachen italienisch, liebten die Sonne, das Mittelmeer und die üppige farbenfrohe Natur, die oft Thema ihrer anderen Passion, der Fotografie, wurde. Ihr beliebtestes Reiseziel war immer Ligurien, die Riviera dei Fiori. Dort “entdeckten” sie Conna, eine winzige Ortschaft, eine Gruppe von steinernen Häusern, gelegen an den Ausläufern des Apennin, eingetaucht in Pinien, Ginster und Buschwald. Dort verbrachten sie viele Wochen und sammelten reiche menschliche und natur- wissenschaftliche Erfahrungen. Bedeutsam waren auch ihre Reisen in die USA, wobei die interessanten entomologischen Forschungen verbunden waren mit den Zusammentreffen mit der Familie des Sohnes. Eberhard Jäckh verbrachte seine letzten Lebensjahre zu Hause in Hörmans- hofen gestärkt durch die Liebe seiner Frau und seiner kleinen Enkelin Gian- nina, die viel in seiner Nähe war und viel von ihm gelernt hat. Er genoß ihre zärtliche Liebe, die wohl dazu beigetragen hat ihn bis ins 92. Lebensjahr auf- recht zu halten. 94 In der Entomologie gehört Eberhard Jäckh zu den bedeutenden deutsch- sprachigen Forschern, die die Grundlage für die moderne Lepidopterenfor- schung gebildet haben. Er hat seine während der Studienjahre gewonnenen technologischen Erkenntnisse für die entomologischen Forschungen benutzt und dabei neue Lösungen und hervorragende Ergebnisse erzielt. Unter ande- rem machte er technische Experimente für den Nachtfang. Durch eine Reihe von Versuchen kam es zur Erfindung einer leichten sehr wirksamen tragbaren Lampe, die er auch für Kollegen anfertigte. Als einer der ersten wandte er die Methode der Artenbestimmung durch die Untersuchung der Genitalien an. Mehr als 11 000 mikroskopische Präparate wurden mit den verschiedensten Färbetechniken angefertigt, um besonders scharfe Fotos davon zu erhalten. Denn auch die Mikrofotografie wurde mit Sorgfalt betrieben, bearbeitet im eigenen, sinnvoll mit einfachen Mitteln ein- gerichteten Labor, assistiert von seiner Frau, die professionelle Fotografin ist. So sind seine ganzen Forschungen durch Bilder belegt. Er hinterläßt ein ein- drucksvolles Archiv, das aus über 20 000, nach der systematischen Mikro- lepidopterenordnung klassifizierten Bildern besteht. Dabei sind auch ca. 100 Corodia-Filme, die Schmetterlinge in ihrer natürlichen Umwelt zeigen, sowie ca. 1 000 Schwarzweißfilme. Jede studierte Art ist dokumentiert im Entwick- lungsstadium, wenn möglich in der Natur, mit Genitalfotos beider Geschlechter, in Variationen, sowie manchmal mit Fotos der Larve oder der Spuren an der Futterpflanze. Die Sammlung Jäckh ist von sehr hohem wissenschaftlichen Wert. Sie umfaßt ca. 75 000 perfekt präparierte und etikettierte Exemplare, sorgfältig geordnet in großen, von Jäckh selbst gefertigten Holzkästen. Der Hauptkern besteht aus europäischem Material, sowie einer großen Anzahl in Nordamerika gesammelter Exemplare. Manche Exemplare wurden gezüchtet, um die Biologie der Microlepidopteren zu beobachten, vor allem der “Minierer”, wie Nepticulidae, Lyonetiidae, Gra- cillaridae und Coleophoridae. Dazu gibt es auch eine wichtige Sammlung von sorgfältig katalogisierten minierten Blättern. Die Bibliothek enthält ca. 150 Bände, teils seltene Exemplare, mit Widmungen und Notizen der Autoren sowie ca. 2000 Sonderdrucken von Entomologen der ganzen Welt. Die gesamte Sammlung wurde schon vor Jahren dem Smith- sonian Institution in Washington, USA, übereignet, das somit eine der wich- tigsten und weltbekanntesten Privatsammlungen bekam. Jäckhs wissenschaftliche Veröffentlichungen sind nicht so zahlreich, weil er die große Menge seiner Erkenntnisse immer sehr vorsichtig darstellte. Aber die, die er hinterlassen hat, sind von hohem wissenschaftlichen Wert meistens durch 95 Fotos dokumentiert. Somit ist Jäckh einer der ersten Autoren, der der guten Fotografie, zwecks besserer Objektivität, den Vorzug vor der Zeichnung gab. Im Laufe seiner Tätigkeit hat Jäckh verschiedene Gruppen und Familien der Lepidopteren bearbeitet (Gracillariidae, Lyonetiidae, Gelechiidae, Coleopho- ridae, Tortricidae, Pterophoridae, etc.), was seine umfangreichen Kenntnisse über Microlepidopteren beweist. Unter anderem hat er eine Revision der Gat- tung Batia Stephens und Pseudatemelia Rebel (Oecophoridae) vorgenommen. In den letzten Jahren hat er sich auf die Familie der Scythrididae spezialisiert und einige wichtige Beiträge erbracht mit der Revision verwandter Gruppen und der Beschreibung neuer Arten. Mit großer Bescheidenheit hat er nach 1978 mit der Veröffentlichung seiner wissenschaftlichen Arbeit aufgehört, um “altersbedingte Fehler” zu vermeiden. _ Fortgesetzt hat er seine Arbeiten im Archiv, welches viele neue Arten, sowie Arten der Gattung Scythris enthält, die auf eine Beschreibung warten. Eine der ihn begeisternden Gruppen war die Alucita, über die er die Basis für eine komplette Revision der palearktischen Fauna vorbereitet hat. Glücklicher- weise ist diese Arbeit nicht verloren. Wieder aufgenommen und ergänzt von Jäckhs jungem “Schüler” Axel Scholz, ist sie vor kurzem veröffentlicht worden. Ich habe Eberhard Jäckh 1973 in Conna kennengelernt. Damals entstand zwischen uns eine brüderliche Freundschaft, mit gegenseitigen Besuchen und gemeinsamen wissenschaftlichen Forschungen an der Riviera, auf den Hügeln des Monferrato, auf dem Monte Baldo, der Insel Krk, etc. Wir verbrachten miteinander viele unvergeßliche Stunden. Wir suchten Raupen und minierte Blätter, saßen neben der brennenden Lampe an einem xerothermischen Hang, diskutierten unaufhörlich über die Natur, planten Forschungen, Exkursionen und Publikationen. Aber oft sprachen wir auch über das Leben und die Ge- schichte dieses Jahrhunderts, das er selbst dahinfließen sah. Ich verdanke Eber- hard den größten Teil meiner Kenntnisse über Microlepidopteren. Besonders über alles, was ich über die Technik der Mikroskopie, Mikrofotografie, und der Sammlungs- und Lichtfangmethoden weiß. Alles wurde mir mit großer Geduld und Hingabe erklärt, voller Sympathie und Großherzigkeit. Aber viel verdanke ich ihm auch von einem menschlichen Gesichtspunkt aus. Es war eine echte Lebensschule mit unvergeßlicher Korrektheit, Ehrlichkeits-, Zähigkeits-, Freundlichkeits-, Bescheidenheitslehren und einer riesigen Liebe zur Natur.

Présentation par le Prof. Emilio Balletto, President de la Societas Europaea Lepidopterologica. Vient de paraître le troisième volume des «Memorie» de l’«Associazione Natu- ralistica Piemontese», qui depuis quelques années publie aussi un intéressant Bulletin dédié surtout à l’histoire naturelle subalpine. Ce volume des «Memorie» est monographique et comprend seulement le travail de Giorgio Baldizzone relatif aux Coleophorides de la zone Irano-Anatolienne et des régions limi- trophes. Après l’importante révision des Coleophorides chinois, de l’Inde, de l'Australie et de l’Afrique tropicale, Baldizzone nous présente aujourd’hui en détail la faune du Proche- et Moyen-Orient. Ce travail représente sa 75° contri- bution à la connaissance de cette vaste et complexe famille des Microlépi- doptères Gelechioidea, dont il est depuis longtemps un spécialiste reconnu. Comme le rappelle dans sa préface Emilio Balletto, Président de la «Societas Europaea Lepidopterologica», la région irano-anatolienne est très peu connue, non seulement en ce qui concerne les microlépidoptères ; le travail de Baldiz- zone doit donc être particulièrement apprecié pour l’évidente et vaste contri- bution qu'il apporte au progrès des connaissances relatives à la faune des Lépidoptères de cette importante zone de la Région Paléarctique. Dans cette monographie, dédiée à la mémoire de Eberhard Jäckh récemment disparu, sont traités 310 taxa appartenant aux Coleophorides, dont 84 sont ici décrits pour la première fois sur la base d’un large matériel provenant en majorité des campagnes de recherche de microlépidoptéristes connus, parmi lesquels les plus importants sont sans doute Fritz Kasy, Wolfgang Glaser, Hans Georg Amsel et Eva Vartian. Les nouveaux taxa appartiennent tous au genre Coleo- phora, sauf une espèce du genre /schnophanes. L’auteur a en outre fixé 30 lectotypes et le néotype de C. gypsophilae Christoph, 1862 (= C. vicinella Zeller, 1849). Enfin sept nouvelles synonymies sont reconnues ; ces dernieres, ajoutées aux nombreuses déjà signalées par Baldizzone lui-même ou par d’autres auteurs, permettent de compléter la révision nomenclatoriale des taxa paléarctiques. Comme d’habitude, la très abondante iconographie qui accompagne le travail est très claire et parfaite sur le plan technique, soit en ce qui concerne l’habitus des adultes — il est dommage que les hauts frais d’impression ne permettent 100 pas de les reproduire en couleur comme on l’a fait sur la couverture avec la splendide planche du jeune entomologiste Fabrizio Pensati! — soit en ce qui concerne les genitalia des deux sexes. Ce travail, d’apres une indication tres claire de son auteur, veut seulement mettre a jour la connaissance des Coleophorides de la region irano-anatolienne au sens large, en renvoyant à des contributions ultérieures la révision moderne de la systématique du groupe et toute autre considération zoogéographique. Dans sa contribution en effet, Baldizzone maintient pour l'instant la subdivision classique donnée par Toll, qui divise les Coleophorides en plusieurs groupes pas nécessairement naturels, reconnus sur la base des plans de structure des genitalia des deux sexes. En lisant avec attention la monographie, on peut de toute façon dejà obtenir plusieurs indications zoogéographiques tout à fait intéressantes qui nous permettent de confirmer ou de mieux comprendre le peuplement des régions anatoliennes, arabes et du bassin touranique. De toute façon, ce volume, à tirage limité à 400 copies à cause des frais d’im- pression élevés auxquels l’auteur a dû faire face lui-même pour la plupart, est non seulement à conseiller vivement à tous ceux qui étudient les Lépidoptères, mais aussi à tous ceux qui désirent augmenter leurs connaissances en matière d’entomologie et de zoogéographie. Pietro PASSERIN D’ENTREVES, Dipartimento di Biologia Animale, Università di Torino, Via Accademia Albertina 17, I-10123 Torino (Italie) Index of economically important Lepidoptera. Bin-Cheng Zhang, 1994. 599 Seiten, gebunden. CAB International, Wallingford, Oxon, UK. ISBN 0-85198-903-9. £ 50 ohne, £ 70 mit Diskette. Das Commonwealth Agricultural Bureau International (CABI), wurde 1928 gegründet. Eine der wesentlichen Aufgaben des CAB’s ist die Herausgabe von Referateorganen über die Weltliteratur im Agrarbereich im weitesten Sinne. Unter anderem erscheint das ”Review of Agricultural Entomology” (RAE) (früher : "Review of applied Entomology”) 1994 bereits im Volume 82 und zwar gegründet 1913, also schon vor der Etablierung des CABI. Da jähr- lich ca. 10.000 Arbeiten referiert werden, hat sich im Laufe der Jahre natür- lich ein enormer Datenbestand angesammelt. Verständlich, daß dieser riesige Fundus nach zusätzlichen ‘Ertragsmöglichkeiten’ durchforscht wird. Begrüßens- wert für die ‘User’ der Reviews, wenn ihnen das geballte Wissen, praxisgerecht serviert wird. Praxisgerecht bedeutet in diesem Falle, daß Herr Zhang aus dem RAE-Datenbestand, alle Lepidopteren herausselektiert hat, die seit 1913 in der Literatur eine Erwähnung als “Pflanzenschädlinge’ fanden. Parasiten des Menschen und der Tiere sollen separat behandelt werde. Eine derartige Kompilation bedeutet für jeden angewandten Entomologen eine sehr große Hilfe. Dafür sei Herrn Zhang und dem CABI Dank. Schließlich hat nicht 101 jeder die technischen Einrichtungen und die finanziellen: Möglichkeiten, die leider sehr teure elektronische Datenbank des CABI zu benutzen. Allerdings möchte ich einige ‘Schwachstellen’ auflisten, die ich gerne bei einer Neuauflage beseitigt sehen würde. Daß bei der großen Datenfülle auch mal etwas verloren geht, dürfte verständ- lich sein. Einige wenige Arten habe ich vermißt, so zum Beispiel Duponchelia fovealis (in RAE 1991 ; no. 743, 5542 und 6335). Die Angaben zur geogra- phischen Verbreitung sind immer mit Vorsicht zu handhaben, da viele Länder nicht sehr meldefreudig sind. Allerdings hat Herr Zhang auch nicht alle An- gaben aus den Reviews übernommen, so zum Beispiel bei Opogona sacchari. Ein besonderes Problem sind die Wirtspflanzenangaben. Wenn bei Epichoristo- des acerbella nur drei Wirtspflanzen genannt sind, so ist mir dies unverständ- lich. Die Larve dieses Tortriciden ist zweifellos polyphag und man könnte ohne weiteres 20 bis 30 Wirtspflanzen nennen bzw. der Literatur entnehmen. Beim European corn borer Ostrinia nubilalis hätte er etwa 300 Pflanzenarten aufführen können. Aus Platzgründen (oder auch aus Zeitgründen ?) wurde wohl selektiert. Wäre es, in diesem wie in ähnlichen Fällen, nicht besser gewesen, wirklich nur die Hauptwirtspflanze(n) anzugeben und dann auf die Polyphagie zu verweisen ? Personen, die diese Lepidopteren nicht näher kennen, könnten sonst solche unvollständige Auflistungen für bare Münze nehmen. Die Ver- mischung der ‘common names’ mit den wissenschaftlichen Namen in den Host Records dient auch nicht gerade der besseren Übersicht. Etwas ganz wichtiges für den angewandten Entomologen fehlt jedoch total : ein Wirtspflanzenindex. Es wäre wirklich sehr hilfreich, einen Überblick zu bekommen, welche Lepidopteren an welchen Pflanzen vorkommen können. Da das Buch weitgehend mit Hilfe der EDV geschrieben wurde, dürfte die Erstellung einer derartigen Liste kein Problem darstellen. Der ‘Index of specific and infraspecific epithets’ am Schluß des Buches ist zwar sehr umfangreich, wäre aber mit Seitenangaben besser brauchbar. Vermutlich aus Platzgründen wurde bei den Hinweisen zu den RAE References nur die Bandzahl genannt. Die zusätzliche Angabe der Abstract-Nummer wäre sehr hilfreich und würde das Buch meines Erachtens kaum umfangreicher machen. Insgesamt gesehen, stellt das Buch jedoch auf Grund der ungeheuren Daten- fülle eine äußerst wertvolle Arbeitsgrundlage für alle Biologen, Ökologen und natürlich speziell für Entomologen dar und ist für Entomologen im Bereich Pflanzenschutz eigentlich unverzichtbar. Es wäre sehr zu wünschen, wenn wei- tere derartige Indexe auch für andere Insektenordnungen erscheinen würden. Wolfgang BILLEN Guide pour l’identification des especes francaises du genre Zygaena.

En vente chez l’auteur ; 8 rue Polonaise F-72200 La Flèche. Ce guide publié à compte d’auteur le 19-I11-1994 est destiné à permettre l’iden- 102 tification rapide et sûre de toutes les espèces du genre Zygaena actuellement connues en France. L. Faillie aurait donc pu se contenter de la partie centrale du guide, nous en aurions disposé déja depuis plusieurs années. Ce perfec- tionniste ne pouvait se contenter de cet à peu près. Il a donc cherché à mettre en perspective l’objet du guide. Celui-ci débute par quelques considérations sur les notions biologiques qui conduisent à la systématique bien documentée permettant d'approcher la finesse de la pensée des grands spécialistes contem- porains qui guident l'étude de ce groupe d’espéces. Elles illustrent aussi le bon sens qui privilégie les solutions simples aux consi- dérations trop théoriques ou partielles qui ont souvent obscurci l’horizon des études se rapportant à ce groupe. Suit la liste des espèces du genre Zygaena, tirée de la solution proposée par C. M. Naumann & W. G. Tremewan en 1984, suivie de rappels au sujet de la position de Zygaenidae fossiles vis-à-vis de ce genre et des genres voisins. Les 26 espèces françaises qui sont l’objet du guide, sont ensuite énumérées dans le même ordre. Un intéressant tableau de comparaison avec les pays européens limitrophes ou voisins, permet de visualiser la richesse et la variété des espèces de chacun d’eux. Dans les 18 pages suivantes le lecteur trouvera les traits essentiels d’une diagnose de chacune des espèces françaises qui décrit parfaitement les caractères distinc- tifs externes, complétés par un dessin au trait grandeur nature qui met l’accent sur les parties de l’ornementation alaire ou du corps qu’il faut prendre en compte pour déterminer chaque espèce. Ces caractères sont souvent mis en évidence par une flèche qui attire judicieusement l’attention du lecteur. Pour les espèces présentant une variation importante, L. Faillie n’a pas hésité à réaliser plusieurs dessins qui illustrent les principales sous-espèces ou morphes présentes en France. Il y a ajouté souvent des informations très pertinentes et très à Jour sur la répartition, la génétique, la nomenclature ou la taxinomie. Cette partie centrale du guide permet vraiment de réaliser les déterminations correctes dans la plupart des cas. Les pièges et difficultés essentielles sont d’ail- leurs révélés afin de permettre à tous de travailler avec un maximum de sécu- rité. Le guide est complété par un tryptique amovible regroupant sur trois planches photographiques en couleur, les 72 specimens représentant au moins une fois, grandeur nature, chacune des 26 epèces traitées. Cette disposition permet, lors de la détermination, de comparer le dessin au trait avec la figure en couleur et renforce ainsi la qualité de la détermination. Il convient de saluer le soin apporté au choix des exemplaires reproduits, car ils sont tous en parfait état de fraîcheur et correctement préparés, ce qui est rare dans les publications concernant ce groupe. Pour augmenter l'efficacité des déterminations, l’auteur a ensuite judicieusement regroupé les espèces suivant certains critères ornementaux (anneau abdominal et collerette) puis regroupé à la fin du guide, sur 4 pages, tous les dessins au trait représentant les imagos figurant dans la partie centrale. Quelques considé- 103 rations sur la structure interne des genitalia mäle des Zygaena sont ensuite les bienvenues. Elles permettent de bien comprendre les différences entre Z. minos et Z. purpuralis dont la dissection est obligatoire. Une bibliographie adaptée au guide permettra enfin au lecteur d’approfondir les connaissances qu'il aura acquises à la lecture du guide. En résumé, un petit livre intelligent, fruit de décennies d’études dédiées aux zygènes et de rencontres avec les plus grands spécialistes de la question. Marque aussi d’une volonté de se mettre au service des autres pour les aider à com- prendre. Remercions donc chaleureusement Louis Faillie d’avoir consacré beau- coup de son temps à la réalisation de ce petit fascicule qu’il a tenu à financer de ses propres deniers afin de ne dépendre d’aucune obédience. Faisons bon accueil à ce guide qui, je n’en doute pas, deviendra très vite le compagnon indispensable de vos recherches et de vos promenades à la ren- contre des zygenes.

This has been due to illness in the Editor’s family, on top of increased professional and private commitments during February and March. For the same reason, the SEL “1991-1992 Index of Publications on European Lepidoptera” was also delayed. The situation is again under control and all outstanding correspondence will be dealt with as soon as possible. I am pleased to announce that Dr. Roger Dennis, Wilmslow, GB has joined the Editorial Committee of this Journal. Dr. Dennis, who is well known for his articles and books on ecological lepidopterology, has already been a great help in the processing of a number of manuscripts in English. Such manuscripts from the United Kingdom may now be submitted directly to Dr. Dennis. In addition, M. Yves Gonseth, Neu- chätel, Switzerland has agreed to act as Assistant Editor from June 1995. At the same time, Dr. Hansjürg Geiger will leave us. Dr. Geiger has been an invaluable member of the Editorial Committee since 1986, but wishes to step down due to increased professional commitments. I would like to sincerely thank Dr. Geiger, not only for his editorial contribution, but also for his advice and moral support. Finally, I would like to mention that this Journal ıs now abstracted in BIOSIS and “Current Advances in Ecological and Environmental Sciences”, a CABS review journal. | Steven WHITEBREAD 106 Nota lepid. 17 (3/4) : 107-112 ; 30.1V.1995 ISSN 0342-7536 Anumeta arax Sp. n. from Turkish Armenia (Lepidoptera, Noctuidae, Catocalinae) Michael FIBIGER Molbechs alle 49, 4180 Sore, Denmark Summary During a lepidopterological visit to Turkish Armenia in 1989 a new species of Anumeta Walker, 1858. was found. This ıs described here as Anumeta arax sp. n. In September 1993 a further visit to this area was made. A few notes on collecting in this politically very tense, but entomologically very interesting area are given. Resume Découverte d’une nouvelle espèce d’Anumeta Walker, 1858 au cours d’une expédition lépidoptérologique en Arménie turque en 1989. Description de celle- ci sous le nom d’Anumeta arax sp. n. L’auteur a revisité ces lieux en septembre 1993 et donne quelques indications sur la chasse aux papillons dans cette région, où la situation politique est très tendue, mais qui est très intéressante pour les entomologistes. Introduction Turkish Armenia is one of the most beautiful and lepidopterologically important areas in the western Palaearctic region. However, since 1988 it has not been fully safe to travel, camp or catch insects because of the unstable political situation in the area. The Arax valley is per- haps the most interesting locality of the region. It runs east-west at a low level (at Aralik : 825 m) just north of, and below, the imposing Mt. Ararat. Unfortunately, the Turkish, Armenian and Kurdish peoples all claim sovereignty over the area, which is at present situated ın Turkey. By the end of 1993, the tense situation had become distinctly dangerous for touring lepidopterists who wanted to collect in the area. Together with the Danish lepidopterist, Fritz Schepler, I visited the area at the beginning of September 1993. We collected at night only with “black” lamps (pure ultraviolet 125 watt bulbs and 20 watt tubes), 107 and were as usual met by the very friendly local people, but also by masses of heavily armed, friendly gendarmes and soldiers. Everybody was scared of each other, often with good reason, and this anxiety creates aggression. When I worked in the area in 1989, Nils Esser (a Danish coleopterist) and I were allowed by the gendarmes to camp and catch moths along the asphalt road from Igdir to Aralik, but we had to set up the lamps within 5 metres from the road, and we were not allowed to stay. In 1993 it was impossible — even armed with psychological arguments rehearsed in my mind — to obtain the same permission. We were forced to camp in a storm (only catching with an 8 watt superactinic tube two metres from the car) close to the military camp in the middle of the village of Hasanhan, approx. 30 km west of Aralik. The unexpected, but good records from both visits to the area will be published in a later paper. Here I will only mention the catch in 1989 of a dozen specimens of Drasteria picta (Christoph, 1877), two specimens of Gonospileia munita (Hübner, [1813]), both species new to Turkey, and in 1993 the record of two specimens of Cardiestra vassilinini (A. Bang- Haas, 1927), also new to Turkey and previously only known from the type specimen. In 1989, I also captured one specimen of the genus Anumeta Walker, 1858 which was unknown to me and to everyone to whom I showed it. Not until 1992 in St. Petersburg, visited in connection with the successful SEL Congress in Helsinki, did I find four more specimens of “my” Anumeta in the Zoology Institute, Russian Academy of Science. They were placed under the name caucasica Rjabov, in litt. Dr. Irına L. Sukhareva who kindly helped me during my visit also translated the Cyrillic writing on the labels. The four specimens were all recorded from the Armenian side of the Arax valley (former Armenian S.S.R.) within 10 km from the locality in Turkey where I found it: 10 km north west of Aralik. As the name caucasica to my mind should represent a mountain species further to the north, I have decided to describe it here under the name Anumeta arax sp. n. Anumeta arax Sp. n.

All segments of labial palpi porrect ; first segment light grey, as long as second and third together, latter two black. Antenna of male ciliate, of female filiform. Ground colour of head, thorax and forewing blackish grey. Basal and median area of forewing slightly darker. Black costal spots on and between crosslines. Lines weakly defined except for black terminal line on both wings, which is sinuate with white spots between veins on terminal side. Fore- wing fringes dark grey, whitish on hindwing. Stigmata absent, a black spot near reniform. Hindwing with light greyish median band, terminal area darker than basal. Whitish blotches on termen of hindwing (typical for Anumeta and Drasteria) weakly defined in male, hardly visible in female. Underside light greyish powdered with black scales. Terminal area blackish. Median stigma present on hindwing. MALE GENITALIA (Fig. 3): Valva, juxta, and vinculum rather simple, but uncus prominent, heavily sclerotised, with apical hook. Aedeagus straight, no cornutus, but a light sclerotised band. Vesica short, rounded with small diverticula. Note : The preparation of the vesica was not perfect and the paratype male had already been dissected, so it was not possible to evert. FEMALE GENITALIA (Fig. 4): Ovipositor hairy. Apophyses equally broad their whole length. Eighth segment hairy distally. Ductus bursa weakly sclerotised. Corpus bursa unisaccate, cylindrical, two and a half times as long as broad. 109 Fig. 3. Male genitalia of Anumeta arax sp. n. : holotype. Remarks Because of an urgent need for a revision of the genus Anumeta, which also forms the tribe Anumetini, the exact number of species cannot be stated. A little more than a score of Anumeta species are known, all with a desert and semi-desert, central and southwestern Palaearctic distribution. Only three species are recorded from Europe (FiBIGER & HACKER, 1991), in south-east European Russia. The genus was pre- viously unknown from Turkey. Systematically, Anumeta arax sp. n. is most closest related to Anu- meta fricta (Christoph, 1893), A. fractistrigata (Alphéraky, 1882) and A. cestina (Staudinger, 1884). The name of this new species is derived from the type locality : The Arax valley. 110 Fig. 4. Female genitalia of Anumeta arax sp. n. : allotype. 111 Acknowledgements Dr. Irina L.

The female is described for the first time. The species externally closely resembles E. gleichenella (Fabricius) and E. lambeseella Nielsen & Traugott-Olsen. The structure of male genitalia indicates E. lambeseella to be the closest relative of the species. E. differens is also reported from Corfu, Greece, although the male genitalia show some minor differences. Zusammenfassung Elachista differens Parenti, 1978, wird erneut beschrieben und ausserdem verglichen mit den anderen bekannten westpalearktischen Arten der Elachista gleichenella-Gruppe auf der Grundlage einiger im Rheinland, Deutschland, gefundenen Faltern dieser Art. Das bisher unbekannte Weibchen wird zum ersten Mal beschrieben. Die Art gleicht äusserlich sehr der E. gleichenella (Fabricius) und E. lambeseella Nielsen & Traugott-Olsen. Der Bau der männ- lichen Genitalien zeigt, dass E. lambeseella am nächsten verwandt ist mit dieser Art. E. differens wird ebenfalls nachgewiesen von Korfu, Griechenland, ob- gleich die männlichen Genitalien der dort gefundenen Tiere einige kleine Abweichungen zeigen. Resume Redescription d’Elachista differens Parenti et comparaison de celle-ci avec d’autres espèces ouest-paléarctiques connues du groupe d’Elachista gleichenella en se basant sur quelques exemplaires trouvés en Rhénanie (Allemagne). Description de la femelle, jusqu’à présent encore inconnue. Extérieurement, E. differens ressemble beaucoup à E. gleichenella (Fabricius) et a E. lambeseella Nielsen & Traugott-Olsen. La structure des genitalia mâles montre que cette espèce est la plus proche de E. lambeseella. Elle a aussi été signalée de Corfou, 113 Grèce ; les genitalia mâles des exemplaires de ces deux régions présentent toutefois quelques petites differences. Introduction In the Palaearctic region five Elachista species belonging to the gleiche- nella group sensu TRAUGOTT-OLSEN and NIELSEN (1977) have so far been described : E. gleichenella (Fabricius, 1781), E. regificella Sircom, 1849, E. differens Parenti, 1978, E. lambeseella Nielsen & Traugott- Olsen, 1987 and the eastern Palaearctic E. megagnathos Sruoga, 1990. The description of E. differens was based on three male specimens collected from France (type locality) and Italy. The original description (PARENTI, 1978) contained only a short description of the external characters and a schematic figure of the male genitalia; NIELSEN & TRAUGOTT-OLSEN (1987) therefore ignored this species when describing E. lambeseella (type locality Algeria, Lambése), even though these species are closely related. Additional material has shown that E. diffe- rens 1s rather widespread in Europe. In this paper we give a redescription of this species, including a description of the previously unknown female.

DraGnosis : Externally Elachista differens resembles E. gleichenella (Fabricius), but it is on average larger. Costal and tornal spots are usually separated in E. differens, whereas they almost always are joined in E. gleichenella, forming a fascia (Figs 1-2, 4). These species are readily distinguished by the very different shape of valva, uncus lobes and aedeagus in the male genitalia (Figs 5 and 7). In the female genitalia the diagnostic characters of E. differens are the non-sclerotized an- trum and colliculum, narrower signum and pyriform corpus bursae (Figs 11-12, 14). The colliculum of E. gleichenella is dorsally sclerotized (Fig. 15) ; the corpus bursae is constricted just below middle (Fig. 13) [this character is ignored in TRAUGOTT-OLSEN & NIELSEN (1977: Fig. 401]). The male genitalia of E. differens somewhat resemble those of E. regificella Sircom, but the gnathos is much larger, and the aedeagus 114 Figs 1-4. Habitus of Elachista spp. : 1 — E. differens Parenti ¢ (Nordeifel, Germany) ; 2 — E. differens 9 (Nordeifel, Germany) ; 3 — Holotype & of E. lambeseella Nielsen & Traugott-Olsen (Lambése, Algeria) ; 4 — E. gleichenella (Fabricius) 2 (S. Germany). is straight in E. regificella (Fig. 8). The female of E. regificella has a longitudinal, dentate sclerotization in the colliculum (Fig. 16), which is lacking in E. differens. Based on male genitalic characters E. lambeseella Nielsen & Traugott- Olsen, 1987 seems to be the closest relative of E. differens. Externally E. differens can be separated from this species by the broader forewing and larger size (Figs 1-3). In the male genitalia the uncus lobes are longer and more slender, the valva is narrower, the cucullus of the valva is more elongate and slightly bent and no cornuti are present in the aedeagus (Figs 5-6, 9-10). The female of E. lambeseella remains unknown. Redescription (Figs 1-2, 5, 9-10, 11-12, 14) Labial palpi drooping, slightly curved, leaden grey, third segment slightly shorter than second.

Legs grey, underside of tibia creamy white, tarsal segments with white distal rings. Forewing ground colour mottled black with bronzy sheen ; base shining silvery ; fascia from before middle of costa to middle of dorsum, silvery with bluish or greenish reflection ; triangular costal spot creamy white at costa, towards middle of wing silvery just beyond opposite silvery tornal spot ; an irregular third spot between tornal spot and apex formed by some silvery scales ; especially in female the three spots often joined forming fascia with medial angle towards apex. Hindwing and underside of wings grey. Forewing length 3.5-4 mm in male (n=4), 2.5-4 mm in female (n = 13). Most female specimens smaller than males. MALE GENITALIA : Uncus lobes long, gradually tapering toward rounded tip, with row of stout setae. Gnathos large, rounded.

Juxta lobes separated by short incision medially, almost parallel-sided, truncate, apical margin slightly rounded near the incision ; with short, pointed lateral process. Vinculum rounded, with indistinct median ridge. Aedeagus short and broad, S-shaped ; caecum processed, blunt ; distal part oblique, tapering into strongly pointed distal end, margin of distal opening laterally asymmetrical with elongate carina ; without cornuti. FEMALE GENITALIA : Distal margin of eighth tergite with long setae. Apophyses stout, posteriores three times longer than anteriores. Ostium bursae rounded with strongly sclerotized margins. Antrum very short, funnel-shaped, neither antrum nor colliculum sclerotized. Corpus bur- sae rounded with small internal spines ; signum elongate, dentate. Remarks We consider the series from Greece, Corfu, to belong to E. differens, although the uncus lobes seem to be slightly narrower, and carina of aedeagus is smaller in these specimens. These differences are in our opinion minor, and the material available does not allow taxonomic separation of these populations. Further material is needed for an evaluation of the geographic variation of the species. 118 Acknowledgements B. Krutzsch (Berlin) loaned us the holotype of Elachista lambeseella. R.

LARSEN 358 Coldharbour Lane, London SW9 8PL, U.K. Summary A reexamination of material of Aricia crassipuncta bassoni Larsen, 1974 from Lebanon shows that it differs from A. vandarbani Pfeiffer, 1937 from Iran, with which it had been synonymised, and also from A. anteros Freyer, 1838 [Turkey] and A. crassipuncta Christoph, 1893 [Armenia]. The differences are to be found in wing pattern and shape, and in the male genitalia. The taxon is therefore raised to species rank. Résumé Le réexamen de matériel d’Aricia crassipuncta bassoni Larsen, 1974 du Liban, montre qu’il differe de A. vandarbani Pfeiffer, 1937 d’Iran, avec lequel il avait été synonymisé, et également d’A. anteros Freyer, 1838 (Turquie) et d’A. crassipuncta Christoph, 1893 (Arménie). Les différences sont à trouver dans les dessins et les formes des ailes, ainsi que dans les genitalia mâles. Le taxon est en conséquence élevé au rang d’espèce. In 1974, I described the taxon Aricia crassipuncta bassoni from the high mountains of Lebanon. It belongs in the subgenus Ultraaricia Beuret, 1959, a small group of species characterized by the presence of an unusual inferior lobe in the uncus. On the advice of Dr. Burk- hardt Alberti and Dr. Walther Forster, I allied the Lebanese taxon with A. crassipuncta Christoph, 1893 from Armenia, despite their being separated by a distance of more than a thousand kilometres. I was encouraged to do this also because the Lebanese population was traditionally referred to tentatively as ssp. crassipuncta of Aricia anteros Freyer, 1838. In a paper in this journal, NEKRUTENKO (1980) placed the taxon bassoni as a synonym of A. vandarbani Pfeiffer, 1937 from the Iranian Elburs Mountains on morphological grounds, though he also said it might possibly be a valid subspecies thereof. K. Schurian (pers. comm.), to 23 AA N U. bassoni U. anteros Fig. 1. Uncus and valves of Ultraaricia spp. : U. bassoni from Lebanon (Larsen prep. LAI) ; U. anteros from Anatolia (Ankara area) (Larsen prep. LAJ). whom I gave some specimens, did not agree with this decision, and I had for long wanted to re-examine the issue. After many years, I recently regained access to my genitalia mounts from Lebanon. Examination of a male bassoni shows that the specialized inferior lobe of the uncus is exactly like that of a male A. anteros from near Ankara (Fig. 1). Since the main characteristic of A. vandar- bani is a strong reduction of this lobe, the assignment of bassoni to A. vandarbani clearly becomes impossible (no material of bassoni was available to Nekrutenko). On the other hand, Nekrutenko’s redescription of A. crassipuncta, a poorly known species, makes it clear that it differs more from bassoni than I thought in 1974. A. crassipuncta has very pointed forewings, the underside pattern is less strongly developed, the wings almost wholly lack orange marginal lunules, and the overlay of light scales is blueish- grey rather than greenish. To this must now be added that the valve of bassoni is proportionately longer than in the other three species, and the distal spine is long, jutting well beyond the distal end of the valve. The length of the valve is due to elongation of the basal part, the distal half having the usual proportions. I therefore raise Aricia (Ultraaricia) crassipuncta bassoni Larsen, 1974 to species rank (stat. 122 n.). This also seems the most reasonable solution on biogeographical grounds. Males of A. bassoni (illustrated in colour by LARSEN, 1974) are readily recognized by the grey upperside with a strong, greenish sheen, usually with well developed marginal orange lunules. They are very different from the smaller blue Anatolian males. Females are like those of Aricia agestis Denis & Schiffermüller, 1775 with strongly developed marginal lunules. The haploid chromosome number is n = 23 (LARSEN, 1975), which has also been found in nominate A. anteros, and which appears to be typical for the genus. Hiccins (1975) quotes n = 24 for A. agestis, but I found Lebanese males to have n = 23. There are also occasional records of A. crassipuncta from southwestern Turkey (Hicains, 1966 ; NEKRUTENKO, 1980). It 1s thus possible that a population of A. bassoni exists in the Taurus Mountains, with which the Lebanese butterfly fauna has many other affinities, but I have not seen material from there.

Die vorliegende Arbeit ist Teil einer interdisziplinären, durch geplante Kraft- werksbauten, angeregten Studie im Schweizer Unterengadin. Die Schmetter- lingszönosen unterhalb der Waldgrenze wurden von 1961 bis 1976 mit unter- schiedlicher Methodik erfaßt und durch zusätzliches Datenmaterial bis 1990 ergänzt. Insgesamt konnten 1242 Arten nachgewiesen werden, die alle ein- schließlich der Fundorte aufgelistet sind. In der Schweiz im wesentlichen auf das Unterengadin beschränkte Arten werden zoogeographisch analysiert. Leider konnten hier neuere Ergebnisse über Caryocolum oculatella nicht mehr berücksichtigt werden. Besonders wertvoll erscheint dem Rezensenten die ökologisch orientierte Analyse der Artenbestände im 2. Teil der Studie, die trotz aller vom Autor offen dargelegten Unzulänglichkeiten eine reichhaltige Fundgrube für ähnlich gelagerte Untersuchungen im Mitteleuropa darstellt. Basierend auf den gut dokumentierten pflanzensoziologischen Verhältnissen, sowie den bekannten Daten über Raupenfutterpflanzen wurden die Arten soweit als möglich den unterschiedlichen Vegetationstypen zugeordnet. Die Zönosezugehörigkeit der einzelnen Taxa wurde möglichst exakt vorgenommen und beinhaltet im Sinne von Schwerdtfeger (1975) mehrere Kategorien von zönoseigenen Arten bis zu Irrgästen. Besonders hohe Diversitätsraten wurden im Koelerio-Poetum xerophilae (236 Arten), im Vincetoxico-Festucetum sulcatae (166 Arten) sowie im Violo-Alnetum incanae (116 Arten) nachgewiesen werden. Die Pionier- standorte des Inn sind erwartungsgemäß artenarm, weisen aber einige wichtige Vorkommen auf wie z.b. Merulempista cingillella (Tamariskenzünsler). Die Studie ist trotz des relativ hohen Preises allen ökologisch orientierten Lepidopterologen wärmstens zu empfehlen, und untermauert die Bedeutung von Schmetterlingserhebungen für Aussagen über die Wertigkeit von Lebens- räumen.

Summary A cytotaxonomical study in the main distribution areas of Agrodiaetus ripar- tii, A. fabressei, A. ainsae and A. fulgens revealed differences between these species. In the species with brown males, A. ripartii has n = 90 with two macro- chromosomes and A. fabressei the same chromosome number, but three large chromosomes. In the species with blue males, A. fulgens (considered here a true species) and A. ainsae have n= ca. 103 and n= 108 with two and six macrochromosomes respectively. Macrochromosomes proved to be the best genetic marker to identify the species of Agrodiaetus in the Iberian Peninsula. By combining karyological and morphological data we were able to construct detailed UTM maps for the four species. A. ripartii is found from Catalonia to the Cantabrian Mountains, in the south to the Sistema Ibérico, A. fabressei flies in the Sistema Ibérico and Andalusian Sierras, A. fulgens is a Catalonian species with a very restricted distribution range and A. ainsae lives in the Central and Western Pyrenees and the Cantabrian Mountains. The taxon recently described as A. violetae is considered a subspecies of A. fabressei, based on the similar chromosome morphology and number. The group seems to have evolved very quickly karyologically, but morphological and ecological differences are not so evident. Resumen El estudio citotaxonömico en las principales areas de distribuciön de Agro- diaetus ripartii, A. fabressei, A. ainsae y A. fulgens revelö diferencias entre las especies. Las especies de machos castafios A. ripartii y A. fabressei tienen respectivamente n = 90 y dos macrocromosomas y el mismo numero de cromo- somas, pero con tres cromosomas grandes. En el caso de las especies de machos azules A. fulgens (elevada aqui a la categoria de especie) y A. ainsae tienen n=ca. 103 y n= 108 con dos y seis macrocromosomas respectivamente. Los macrocromosomas resultaron ser el mejor marcador genético para identificar las especies del género en la Peninsula Ibérica. Mediante el analisis conjunto de datos cariolögicos, morfolögicos y de distribuciön (estudiada con mapas 125 detallados en proyecciön UTM), obtnemos una idea clara de la taxonomia del grupo. Asi A. ripartii se encuentra desde Cataluña hasta el Sistema Cantabrico, siempre al norte del Sistema Ibérico, A. fabressei vive en el Sistema Ibérico y sierras andaluzas, A. fulgens esta restringida a unas pocas localidades cata- lanas y À. ainsae vive en los Pirineos Centrales y Occidentales y los Montes Cantäbricos. La recientemente descrita A. violetae se considera una subespe- cie de A. fabressei por su similar numero y morfologia cromosémicas. El grupo parece haber evolucionado muy räpidamente desde el punto de vista cariolögico, mientras que las diferencias morfolögicas y ecolögicas no son tan patentes. Introduction The taxonomy of the genus Agrodiaetus Hübner, [1822] is one of the most complicated among Palaeartic butterflies. The genus lives mainly in the Mediterranean and Middle East, but can also be found in Central Europe and Russia (Hiccins & HARGREAVES, 1983 ; KuDRNA, 1986). The biology is similar in the different species of the group, the larvae use sainfoin (Onobrychis) as foodplants, and overwinter in this stage, feeding during the following spring on the young leaves of the plant (SCHURIAN, 1976; Lepidopterologische Arbeitsgruppe der Schweiz, 1987 ; Manıno et al., 1987; MUNGUIRA, unpublished data). Pupation takes place at the base of the plant and adults begin to fly usually after a month. The flight period ranges from July in hotter places to August in populations living at higher altitudes. Interest in the group lies in the controversial taxonomic position of most species. Before chromosome studies were made, morphological research attempted to provide a clear view of the systematics and taxonomy of the group. Some comprehensive reviews attempted this difficult task (FORSTER, 1961), but the confusion generated by this approach proved the inadequacy of the methods based solely on morphological analysis. Chromosomic studies started by de Lesse in 1952, clearly showed that morphology itself was not enough to under- stand relationship among the species (DE LESSE, 1960a). Unfortunately these studies are not a panacea either and the species’ chromosome numbers also show a complicated pattern, with very different chromo- some numbers in otherwise identical taxa. This shows how hard it is to give simple answers to difficult questions in a group that is under- going a splitting process at the moment we are studying it. For example, in Italy the taxa previously grouped under the name Agrodiaetus ripar- tii (FREYER, 1830) has been split into three different species with different chromosome numbers : A. humedasae Toso & Balletto, 1976 126 with n = 38 ; A. galloi Balletto & Toso, 1979 with n = 66 ; and A. ripar- tii with n = 90 (TRoIANO et al., 1979). AGENJO (1947) lists the Spanish species as Plebejus (Agrodiaetus) damon (Denis & Schiffermüller, 1775), P dolus (Hübner, [1823]), P. admetus (Esper, 1785) and P ripartii. FORSTER (1961) describes ainsae as a subspecies of dolus and considers Agrodiaetus as an independent genus. Following the popular book by GOMEz-BusTILLo & FERNAN- DEZ-RUBIO (1974) the Iberian species of the genus are Agrodiaetus damon, A. dolus, A. fabressei (Oberthür, 1910), A. ripartii and A. ainsae Forster, 1961, to which A. violetae Gomez-Bustillo, Expösito & Martinez, 1979 was added later as a new species. A. fabressei cor- responds to what AGENJo (1947) named P admetus, now known to be restricted to Eastern Europe and Asia Minor. There is a tendency to split the species of the group into new species whose validity has been discussed in several reviews (see for example FERNANDEZ-RUBIO, 1992). Hıscıns (1975) also considers within the genus the species A. amanda (Schneider, 1792), A. thersites (Cantener, 1834) and A. escheri (Hübner, [1823]), but although this inclusion has strong arguments in its favour, the resulting genus is less homogeneous. KuDRNA (1986: 161, 229-231) in the latest European checklist grouped the Agrodiaetus within the genus Polyommatus and listed the following species as present in Spain : P ainsae, P. damon, P. dolus, P. fabressei, P. ripartii, and P. violetae. The first three taxa have blue males and the last three brown males. The inclusion of Agrodiaetus in Polyommatus is not supported by recent research (LELIEVRE, 1992) and we do not assume it for simplicity. We centered our study only in the Agrodiaetus sensu stricto group (following Hiccins & RırLry, 1970), but excluded A. damon which is a fairly distinct species that has never been mistaken with the others anywhere in its range. The objectives of our study were to identify the specific entities of the Agrodiaetus group living in the Iberian Peninsula based on cytotaxonomical and morphological information and to give accurate UTM distributions for every species. Materials and methods Chromosome number studies were made on male testes of at least five specimens for each species and/or geographical area. Testes were dissected in situ under a stereomicroscope in distilled water and fixed with a solution of ethanol : acetic acid (3:1). They were kept at ca. 5°C until analysis was possible. After staining the samples with lacto- propionic orceine they were observed under a phase contrast microscope 127 to count chromosomes using the squash technique (Lorkovic, 1990) with small fragments of the testes. Brown males were studied from Sierra de Cazorla (SW Spain), Sistema Ibérico (Central Spain), Cata- lonia (NE Spain) and the Cantabrian Mountains (N Spain). Blue males were studied from Catalonia and the Pyrenees. This covered all the taxa previously described and the geographic range of the group in the Iberian Peninsula and was considered enough to give an idea of the chromosome numbers for each area and species. Distribution data were collected using faunistic records from the literature and from specimens in the collections of the following Spanish institutions : Museo Nacional de Ciencias Naturales, Sociedad de Ciencias Naturales Aranzadi, Museo de Ciencias Naturales de Vitoria, Museo de Zoologia de Barcelona and Universidad Autönoma de Madrid. Private collections from Fidel Fernandez-Rubio, Jose Luis Yela, Arcadi Cervellé, Jose Maria Font and Jose Luis Nuñez and personal communications from Albert Maso, José Bellavista and Fran- cisco Abös were used for distribution records. Data were also gathered visiting a total of 36 localities from 12 different Provinces in which specimens were taken for morphological analysis. The specimens used for this study are preserved in the zoological collection of the Uni- versidad Autönoma de Madrid (UAMZ). A database was created to process all the faunistic data with information on localities, provinces, dates, UTM coordinates, altitudes and bibliographic references. This is available upon request for anyone interested, but its volume (more than 700 records) made its inclusion in this paper impossible. Maps were produced using a commercial program for automated carto- graphy (CYANUS) for the Iberian Peninsula and Balearic Islands. Each record was assigned to a particular species using karyological data for the localities from which chromosome studies were made. For the rest of the localities identification was based on geographical and morpho- logical affınities with the former records. The morphological analysis of the records for which we had specimens, showed that the individuals identified by this method had the typical morphology of the species to which they were assıgned. The biology of the group was studied at the different localities visited, where we gathered data on foodplants, overwintering stages and im- mature stage morphology. 128 Table 1 Localities, sample size and chromosome numbers of the studied material and all the literature references for Agrodiaetus species in the Iberian Peninsula. “No. males” refers to the number of males that produced metaphase I plates suitable for chromosome counts and the total sample is given in brackets.

From these results it is clear that the best genetic marker for the identification of the species of the group in the Iberian Peninsula is the number of macrochromosomes (see WHITE, 1973 for the use of the term, that appears as “gros chromosomes” in DE LESsE, 1960b). These can be defined in Lepidoptera as chromosomes with two to four times the normal size, located in the centre of metaphase I plates and surrounded by normal-sized chromosomes (Figs 1-4). The location of macro- chromosomes contrasts with their peripheral location in Orthoptera, amphibians and reptiles (WHITE, 1973). In lycaenids the number of macrochromosomes is always low while in the other groups it usually outnumbers that of microchromosomes (see WHITE, 1973 for compa- 129 Figs 1-4. Metaphase I plates. 1 — Agrodiaetus fulgens. (Taradell, Barcelona Province, type locality for species) n = 103, six macrochromosomes ; 2 — Agrodiaetus fabres- sei (Penalen, Guadalajara Province), n = 90, three macrochromosomes ; 3 — Agro- diaetus ripartii (Collsuspina, Barcelona Province), n = ca. 88, two macrochromosomes ; 4 — Agrodiaetus fabressei violetae (Sierra de Cazorla, Jaén Province), n = 90, three macrochromosomes. 130 rison), and it is probable that these configurations depend on mechanical aspects of the cell division process. The number of chromosomes is also distinctive, but the metaphase I plates of Agrodiaetus have large chromosome numbers and accurate counts are difficult in most cases. The results from Table 1 support the following species’ arrangements : A. ainsae with n — ca. 108 lives in the Pyrenees and a wide area sur- rounding the Cantabrian Mountains, whereas in Catalonıa the speci- mens previously assigned to A. dolus should now be considered a distinct species. The name A. fulgens (Sagarra, 1925) is valid for this species, because it was given to what was thought a subspecies of A. dolus in the same localities where the samples for chromosome studies were taken. The reason for considering fulgens a distinct species is the different chromosome number (n = ca. 103, while dolus has n = 124 and ainsae n = 108) and above all, the different number of macro- chromosomes of these specimens (six for fulgens (Fig. 1) as opposed to four in dolus, DE LESSE, 1961b). de Lesse (1962, 1966) only gives the chromosome number for A. ainsae and does not provide figures for it, but our specimen from Peñahorada (Burgos Province, northern Spain) had two macrochromosomes although the metaphase I plates we obtained were not suitable for accurate chromosome counts. The number of macrochromosomes is therefore six in A. fulgens, four in A. dolus and two in A. ainsae. Although our sample for fulgens 1s very small (only 3 specimens with metaphase I plates), the separation of ainsae from dolus was made with similar samples (five specimens, DE LESSE, 1962). Moreover it is not chromosome number, but the number of macrochromosomes that we consider to be a strong argument to split fulgens from ainsae, because it is highly improbable that specimens with such a different chromosome morphology can belong to the same species. A. ripartii and A. fabressei share the same chromosome number (n = 90) but clearly differ in the morphology of chromosomes, fabressei having three (Fig. 2) and ripartii two (Fig. 3) macrochromosomes. DE LESSE (1960a, Table 1) states that fabressei has four macrochromosomes, but after examining our photographs and drawings we have concluded that the species clearly has three large chromosomes constantly seen in all the metaphase I plates. The difference between de Lesse’s results and ours is due to the existence of one or two medium sized chromo- somes that in some plates resemble macrochromosomes, but are driven out of the centre of the spindle in a majority of our figures from fabressei. Large chromosomes are always located in the centre of meta- phase I plates, and they are easily spotted when comparing long series of plates. This has been possible with the material from the Sierra 131 de Cazorla, previously regarded as A. violetae, where the presence of three macrochromosomes is clear (Fig. 4). The latter race has therefore a true fabressei karyotype, which supports the idea outlined in FER- NANDEZ-RUBIO (1992) that it is a subspecies of fabressei and not of ripartii, as has been proposed (BALLETTO, pers. comm.). The distribution of both karyotypes seems to be clearcut from the data in Table 1. A. ripartii 1s a species living from the Cantabrian Mountains to the Catalonian Pyrenees whereas A. fabressei lives in central Spain and in some southern mountain ranges. Morphology There is not a single character clearly separating all ripartii specimens from fabressei, and ainsae from the Catalonian species fulgens. In the first case a group of characters can identify most of the specimens, but in the latter this proves to be very difficult. Generally speaking fabressei lacks the white band along the v4 on the hind wing’s underside, but there is a great variability on this character. Traditionally brown males without the white band have been regarded as fabressei, and this has produced records of the species in the Pyrenees (GöMEZ, 1988) and Catalonia (GOMEz-BusTILLO & FERNANDEZ-RUBIO, 1974). The book by MANLEY & ALLCARD (1970) is unusual because it illustrates an individual with white band taken at Penahorada (Burgos Province) under the name fabressei and a very similar specimen (with white band) from Albarracin (Teruel) as ripartii. These identifications are in dis- agreement with our karyological results. On the other hand a white band is also present in some fabressei specimens leading some authors to consider these as ripartii (GOMEZ-BUSTILLO & FERNANDEZ-RUBIO, 1974 ; MANLEY & ALLCARD, 1970 for the male collected in Albarracin, Teruel). The Catalonian race agenjoi Forster, 1965 has been considered a different species (Hıscıns & HARGREAVES, 1983), a subspecies of fabressei (MANLEY & ALLCARD, 1970 ; GOMEz-BuUSTILLO & FERNAN- DEZ-RUBIO, 1974) or a subspecies of ripartii (AGENJO, 1964 ; DE LESSE, 1968, PÉREZ, 1979). Black spots on the underside are larger in fabressei than in the normal ripartii, but again the Catalonian specimens are an exception to this and resemble typical fabressei. Another distinctive feature of fabressei has traditionally been the enlargement of the black spot between v2 and v3 in the forewing’s underside (DE LESSE, 1968), but our material from the whole geographic range of both species does not support the distinctness of this feature. The apical angle of the forewing is smaller in fabressei than in ripartii. Althoug this seems to be a constant character, it is hard to measure and by itself is not use- ful enough to identify all the specimens clearly. The third supposed 132 species with brown males, A. violetae, has a mixture of morphological characters from ripartii and fabressei with a white band in the underside of the hindwing (absent in six of our sample of 22 butterflies) and a small angle in the apex of the forewing. As a result of ıts chromo- some morphology we consider it a subspecies of A. fabressei. Although there are exceptions to all the characters mentioned above, most of the specimens can be identified by a mixture of characters. Therefore specimens without white band in the underside, large spots ın the underside and small apical angle can be considered fabressei, provided they are in the distribution range of the species. Individuals outside the normal species’ range need chromosome study to be sure of their identity. As far as the species with blue males is concerned identification is also difficult. A. fulgens has traditionally been regarded as a race with brighter blue and lack of the white band ın the hindwing’s under- side. These two features are useful for most specimens, but again a substantial morphological variation takes place in ainsae for both characters, making individual diagnosis difficult in some cases. Distribution Given that it is very difficult to identify the species of the group based on morphological features, we considered the possibility to use both chromosome numbers and distribution data to assign a given individual to a species of the group. In almost all the studied northern localities, three Agrodiaetus species live together : damon, which is a well cha- racterized distinct species, a species with blue males and a species with brown males. We assumed that each area has a sıngle brown and/or blue species (this was confirmed by the chromosome study) and by mapping the species tried to define areas isolated by barriers separating species. In the localities of the Sistema Iberico (Central Spain) only a species with brown males flies together with damon and the chromo- some studies revealed this to be fabressei (DE LESSE, 1960b, and our observations, Table 1). A. fabressei (Fig. 5) is therefore restricted to the Sistema Iberico, a mountain range running from north to south in Central Spain and to the Sierras of Andalusia. The species lives in the Serranias of Cuenca and Albarracin, the high plains of La Alcarria, some calcareous out- crops in Segovia Province and north of Madrid, and reaches the Province of Soria in the north, being isolated from ripartii by the Picos de Urbiön, whose northern slopes flow down to the Ebro Valley. A. fa- bressei violetae is found in a total of twelve UTM squares (10 X 10 km) 138 Fig. 5. Distribution of Agrodiaetus ripartü (circle) and A. fabressei (star) in the Iberian Peninsula. Each symbol represents the presence of the species in a 10 X 10 km UTM square. Open symbols represent localities where chromosome studies were available. from four mountain ranges in Southern Spain (Sierra Tejeda, Sierra de Almijara, Sierra de Cazorla and Sierra de Alcaraz). A. ripartii (Fig. 5) lives over a wide area, from Catalonia through the Pyrenees to the Cantabrian Mountains, where it lives mainly on the southern slopes. Two subspecies can be distinguised: the Catalonıan agenjoi and the Pyrenean and Cantabrian ripartii, separated by an area that more or less matches the boundary between the Pyrenees and a mountain range running from north to south in eastern Catalonia (Serralada Vertical) in which the species becomes scarce (Fig. 5). DE LESSE (1961a) describes the presence of specimens with a typical ripartii 134 Fig. 6. Distribution of Agrodiaetus ainsae (circle) and A. fulgens (star) in the Iberian Peninsula. Each symbol represents the presence of the species in a 10 X 10 km UTM square. Open symbols represent localities where chromosome studies were available. karyotype in Olocau del Rey (Castellön Province), an area where fa- bressei is widespread. If this finding is confirmed it may be possible that ripartii has some populations more or less mixed with fabressei colonies in this contact zone. A. ainsae (Fig. 6) is the most widespread species with blue males in this area. Specimens from the western Pyrenees and the Cantabrian mountains belong to this species, but not a single locality has been found south to the Picos de Urbiön, suggesting that the southern limit for ripartii is also valid for the blue species of the group. 185 A. fulgens (Fig. 6) has until now been considered a subspecies of dolus (GOMEZ-BuSTILLO & FERNANDEZ-RUBIO, 1974, Hıccıns, 1975). It has only been cited from a handful of localities in Catalonia and between the strongholds of this species and the previous one there is a wide area with scarcity of records that can be seen when the distribution of both species is plotted together (Fig. 6). It should be noted that this lack of records is not a consequence of lack of information, for this is a well explored area. Biology Allthe studied species use Onobrychis as larval foodplants. In the Cata- lonian localities, the Pyrenees, the Sistema Ibérico and the Cantabrian Mountains the foodplant is always O. viciifolia Scop. The only popu- lation that uses a different foodplant is A. fabressei violetae in the Sierra de Cazorla. Its foodplant is O. argentea Boiss., but we do not consider this difference to be relevant with respect to its taxonomic status, because the two plants are ecologically similar, and O. argentea is the only species of this plant genus living in Sierra de Cazorla. In all other aspects the biology of the studied species is very similar. They all overwinter as third instar larvae (we studied this for fabressei, ripartii and ainsae) and pupate during the spring at the base of the foodplant. The fullgrown larva is very similar in species living in the same area. Thus we were unable to distinguish between A. fabressei and and the very different A. damon in Albarracin (Teruel Province), and between A. ripartii and A. ainsae in Jaca (Huesca Province). All the larvae have tentacles and dorsal nectary organs (Newcomer’s gland), and the coloured band in the lateral zone of the larva can have different colours, being yellow in the specimens from Jaca in the Pyrenees and pink in the larvae from Albarracin. Wether this can be a distinctive feature between ripartii and fabressei or just a character related to the ecological peculiarities of the site requires a more comprehensive study. Egg morphology is being studied under the SEM microscope by two of us (MuncuirA & MARTIN, in preparation) and all the species exhibit a very similar chorionic pattern, with no distinctive features among them. Discussion Previous results have shown how complicated a taxonomic study of this difficult butterfly group can be. Although butterfly taxonomy in Europe is often regarded as being settled, there are some groups in which a great deal of research is still needed. Two of the main 136 taxonomic groups within which the boundaries between species are not yet well defined are found in Agrodiaetus, and Polyommatus (Lysandra) of the coridon (Poda, 1761) group (DE BAST, 1985 ; Mensı et al., 1988 ; LELIEVRE, 1992). Our approach to the taxonomy of the group was to begin to identify the different karyotypes found in the Iberian Peninsula. Then we trıed to study as many areas as possible to assign karyotypes to relevant areas from the biogeographical point of view. Plotting this information with distribution maps, we tried to draw accurate maps of every species. The separation of species in contact areas such as the boundaries between A. ainsae and A. fulgens is still tentative and a karyological study of almost every locality is needed to be completely sure. The limit between A. ripartii and A. fabressei also needs some further study, but in this case we think that our proposal is closer to reality because the morphology of specimens from Abejar (Soria) resembles the typical fabressei, with most butterflies lacking the white band on the hind- wing’s underside (MANLEY & ALLCARD, 1970). On the other hand the specimens from the northern slopes of the Sistema Ibérico (e. g. Castañares de las Cuevas in La Rioja) are morphologically true ripartii with the white band present in all the studied material. Some research needs to be done on the identity of some populations close to the town of Morella in central eastern Spain, where DE LEssE (1961a) identified karyotypes belonging to fabressei and ripartii in nearby populations, but never in the same one. This area may prove to be a contact zone for the two species, and the segregation of populations may not be as clearcut as depicted in the distribution maps. In a locality between the towns of Olocan and Forcall, de Lesse (1961a) found males with a typical ripartii karyotype and a single male with fabressei morphology, for which a chromosome study was not possible. Speaking of this fabressei specimen he writes that “on a vu qu’aucun doute ne peut exister sur son identité”. Therefore a contact area between the two species might exist in Morella, but this statement has to be proven through more chromosomic studies. On the other hand, although some authors have reported the two species from the same locality, nobody has yet identified specimens of the two different karyotypes living to- gether. Populations having different chromosome numbers are usually thought to belong to different species. Although DE LEssE (1960a ; 1966) is very cautious to split species by their distinct chromosome numbers, his data have always been used as a proof to make new species’ arrange- ments (GOMEZ-BUSTILLO & FERNANDEZ-RuBIO, 1974 ; Hicains, 1975). Some intraspecific variation in chromosome numbers and chromosome 15% morphology can not be plainly rejected (WHITE, 1973), particularly in such similarly looking and difficult groups as the Agrodiaetus. Never- theless, before a more thorough study is done on the significance of chromosome number variability in the evolution of lycaenids, we assume it is safer to assign populations with different chromosome numbers to different species. This approach was made in most chromo- somic studies in butterflies, as for example to support the separation of A. humedasae (TROIANO, et al., 1979), to split a species complex in several species previously regarded as identical (SOUMALANIEN & Brown, 1984) or as a general rule to explain chromosome number variability (see WHITE, 1973). On the other hand a karyological feature of great taxonomic importance has emerged during our study: the variability of the number of macrochromosomes observed in the centre of metaphase I plates. This character was previously used by DE LESSE (1960b), but our data prove that it is the best genetic marker to identify the species of Agrodiaetus in the Iberian Peninsula. We can therefore recognize fulgens by its six macrochromosomes and separate it from ainsae that has only two, whereas the species with brown males differ in having two (ripartii) or three (fabressei) of these large chromosomes. As a conclusion to our study, the Spanish Agrodiaetus with their chromosome numbers and distribution are: A. ripartii (n = 90, two macrochromosomes) living from Catalonia to the Cantabrian Moun- tains, A. fabressei (n= 90, three macrochromosomes) living in the Sistema Ibérico (South to the Picos de Urbiön), the limestone out- crops of Central Spain and some southern mountain ranges (Sierra Almijara, Cazorla, Alcaraz and Tejeda), A. ainsae (n = 108, two macro- chromosomes) from the Pyrenees and Northern Spain and A. fulgens (n = ca. 103, six macrochromosomes) living in Catalonia.

Part II : First instar larvae. This is the second of a small series of keys dealing with mature larvae, first instar larvae, and pupae. They aim at the identification of living specimens.

Zusammenfassung Dieser Schliissel ist der zweite aus einer kleinen Reihe, die sich mit den erwach- senen Raupen, den Eilarven und den Puppen befaßt. Sein Ziel ist das Be- stimmen lebender Tiere. Daher wird auf alle Merkmale, die am lebenden Tier nicht erkennbar sind (z.B. Mandibelformen), bewußt verzichtet. Die Schlüssel könnten vor allem in der Faunistik und für die ökologische Forschung von Nutzen sein. Resume Cette clé est la deuxième d’une petite série qui traite des chenilles — adultes et au stade LI — et des chrysalides. Elle a pour objectif de permettre la détermination des espèces vivantes à ces différents stades. Par conséquent ne sont pas pris en considération les caractères invisibles chez l’animal vivant (p. ex. la forme des mandibules). Ces clés pourraient rendre service en faunistique et pour les recherches sur l'écologie des Sphingidae. 141 Einleitung Eilarven verschiedener Schmetterlingsgruppen sind bisher vorwiegend zur Klärung der Systematik herangezogen worden (z.B. WASSERTHAL, 1970). Die hier wichtigen Merkmale sind jedoch in der Regel erst nach dem Töten des Tieres erkennbar und daher für eine einfache Artbe- stimmung vielfach ungeeignet. Eilarven sind bereits in der Frühzeit der wissenschaftlichen Entomologie ein beliebtes Studien- und Mikroskopierobjekt gewesen (WEISMANN, 1876 ; PouLton, 1885 ; 1886 ; 1888 ; GILLMER, 1904 ; DENso, 1906a,b). Auch ın den letzten Jahren sind Eilarven etlicher Schwärmer beschrieben worden (z.B. HEINIG, 1976; 1978 ; 1981 ; HArBıcH, 1978 ; Pirraway, 1979 ; PELZER, 1982 ; HEINIG & HASLER, 1986 ; FREINA, 1994). Auf die Merkmale, durch die sich verwandte Arten unterscheiden, gehen die Beschreibungen jedoch nur in Ausnahmefällen ein (PELZER, 1988). Von einfachen Bestimmungsschlüsseln für die Präimaginalstadien, mit denen sich bereits ein lebendes Tier bestimmen läßt, könnte neben der Systematik besonders die Faunistik profitieren ; im faunistischen Schrift- tum tauchen Eilarven als Artnachweis bisher nicht auf. Dabei sind Eier oder Eilarven manchmal nicht schwieriger zu finden als die Falter (z.B. PELZER, 1982). Könnte man bereits die Eilarve bestimmen, bräuchte man das fragliche Tier nicht bis zur erwachsenen Raupe oder gar bis zum Falter aufzuziehen — was auf Exkursionen in der Regel nur selten möglich sein dürfte. Die Bestimmung von Eilarven ist ın vielen Fällen erstaunlich einfach. Im Gegensatz zu erwachsenen Raupen weisen sie nämlich nur eine sehr geringe Variabilität auf. Andererseits wirkt die insgesamt nur kleine Zahl verwertbarer Merkmale jedoch limitierend. Systematik, geographische Abgrenzung, Material und Methoden Die verwendete Systematik wird im 1. Teil der Reihe erläutert (PELZER, 1991) ; sie folgt weitgehend der Auffassung von ROTHSCHILD & JORDAN (1903). Der Name Laothoe tremulae (Fischer von Waldheim, 1830) wird durch L. amurensis (Staudinger, 1892) ersetzt (Pirraway, 1993). —— Abb. 1-6. Eilarven europäischer und nordafrikanischer Schwärmer.

Nach dem gegenwärtigen Kenntnis- stand treten 32 Schwärmerarten mehr oder weniger regelmäßig in diesem Areal auf (Tab. 1). Hinzu kommen einige Irrgäste aus Nord- amerika, Afrika und Asien, die hier nicht behandelt werden (Listen in MEERMAN, 1987 und Pitraway, 1993). Die Merkmale der wenigen Hybriden, die aus dem Freiland bekannt sind, vermitteln stets zwischen denen der Elternarten. Die Schlüssel basieren ausschließlich auf eigenen Daten. Sie beruhen auf zahlreichen Zuchten und Freilandbeobachtungen der meisten hier behandelten Arten. Von fünf Arten lag mir allerdings kein Material vor. Es handelt sich dabei um Arten, für die Europa auf dem äußersten Rand ihres Verbreitungsgebiets liegt. 144 IE: ’ is (11 X) c) L. amurens ’ . tiliae (12 X) ; b) tus (14 X). lla S. oce 5) ad) Abb. 2. a) M. quercus (8 X) popul e) Die Aufnahme von R. komarovi in den Schlüssel erfolgt nach einem Farbdia, das mir Prof. Dr. L.T. Wasserthal (Erlangen) dankenswer- terweise überlassen hat. Die noch unbeschriebene Eilarve von S. caecus dürfte der von S. ocellatus sehr ähneln. Aus der einzigen, mir vor- liegenden Beschreibung der Eiraupe von D. elegans geht lediglich her- vor, daß sie ein Horn besitzt (SOFFNER, 1959). Hier und bei den Arten S. gorgoniades und H. osiris kann — anders als bei den erwachsenen Raupen — nicht abgeschätzt werden, wo im Bestimmungsschlüssel man vermutlich ankäme. Zur Bestimmung ist eine Handlupe mit wenigstens 10-, besser 20facher Vergrößerung notwendig. Zur Ermittlung des Horn-/ Afterklappen- längen-Verhältnisses (H/ A, s.u.) besonders geeignet sind Meßlupen mit eingearbeiteter Millimeterskala, wie sie von Briefmarkensammlern ver- wendet werden. Einfache Längenangaben, wie z.B. die Gesamt-Körperlänge, sind als Bestimmungsmerkmal gewöhnlich ebenso unbrauchbar wie simple Farbangaben. Bei einigen Arten werden einige Zeit nach Beginn der Nahrungsaufnahme Zeichnungselemente des zweiten Stadiums mehr oder weniger deutlich sichtbar. Solche variablen Merkmale werden nicht berücksichtigt. Die Färbung der Hartteile ändert sich dagegen während eines Stadiums nicht und ist daher für die Bestimmung geeignet. Auch die Beweglichkeit des Horns ist ein gutes Merkmal : manche Arten können ihr Horn weit nach vorn neigen (Abb. 3d), bei anderen ist es praktisch unbeweg- lich. Wo die Futterpflanzen der Raupen bei der Bestimmung helfen können, werden sie mit aufgeführt. Ein „mathematisches“ Merkmal hat sich als besonders einfach und brauchbar erwiesen : das Verhältnis der Hornlänge relativ zur Länge der Afterklappe (Horn-/ Afterklappen-Längenverhältnis, H/A). Dieses Längenverhältnis läßt sich schon rein optisch gut abschätzen. Bei der Kiefernschwärmerraupe auf Abb. Id beträgt es etwa 1, d.h. Horn und Afterklappe sind etwa gleich lang. Das Schwanzhorn ist bei Eilarven — sofern es nicht beim Schlupf verbogen worden ist — immer gerade. Zur Ermittlung von H/A ist stets die Gesamtlänge des gestreckten Horns zu verwenden. Die Anordnung der einzelnen Arten auf den Tafeln weicht z.T. von der in Teil I ab, um ähnliche Raupen direkt nebeneinander zu stellen. Da die lebenden Eilarven einiger Arten bei Lupenvergrößerung nur schwer zu bestimmen sind, gibt ein Hilfsschlüssel zusätzlich Unterschei- dungsmerkmale des zweiten Raupenstadiums an. 146 Abb. 3. a) H. fuciformis (20 X); b) H. croatica (22 X) ; c) A. tityus (22 X) ; d) D. nerü (16 X).

PORTER (!), Robert W. SCHNEIDER & Brad A. PRICE Biology Department, Bowling Green University, Bowling Green, OH 43403-0212, USA Summary The butterflies Coenonympha gardetta, C. darwiniana and C. arcania are closely related and have parapatric distributions. We studied wing pattern and allozyme variation in three sample sites near Bellwald in Canton Valais, Switzerland in an area where C. gardetta and C. darwiniana meet, and in a C. arcania population from northern Italy. Principal component analysis identified traits that separated the C. arcania population, but separate taxo- nomic groups could not be distinguished in the Bellwald region even when C. arcania was dropped from the analysıs. Allozyme data showed high poly- morphism characteristic of other Coenonympha populations, and also sepa- rated the C. arcania population. F-statistics revealed that the sampled popu- lations at Bellwald, even though separated by up to 2 km, are probably sub- sites within a single large, demographic population. We believe C. gardetta and C. darwiniana should be considered conspecific ; C. gardetta is the older name. C. arcania should provisionally be kept distinct taxonomically, but closer study of contact regions between C. gardetta and C. arcania are required to rule out mere isolation by distance as the reason for the observed level of differentiation. Resume Coenonympha gardetta, C. darwiniana et C. arcania sont des espèces proches parentes dont la répartition est parapatrique. Les auteurs ont étudié le dessin des ailes et la variation allozyme de trois lots provenant des environs de Bellwald (Valais, Suisse), région où C. gardetta et C. darwiniana sont en contact, ainsi que chez une population de C. arcania d’Italie septentrionale. L'analyse des principaux éléments a révélé des caractères qui séparaient la population de C. arcania, mais on n’a pas du distinguer de groupes taxo- nomiques séparés dans les biotopes de Bellwald, même lorsque C. arcania (‘) Corresponding author : Adam Porter at the above address, or E-mail : aporter@opie.bgsu.edu ; Tel. : (419) 372-2691 ; Fax : (419) 372-0224. 153 était exclu de l’analyse. Les données allozymes ont révélé un polymorphisme considérable caractéristique d’autres populations de Coenonympha ; elles ont également séparé la population de C. arcania. Les statistiques F ont prouvé que les populations-échantillons de Bellwald, même séparées par une distance de 2 km, sont probablement des sous-stations à l’intérieur d’une seule et même grande population. Les auteurs pensent que C. gardetta et C. darwiniana devraient être considérées comme co-spécifiques ; C. gardetta est le plus ancien nom. C. arcania devrait être provisoirement conservé comme espèce taxono- miquement distincte. Mais on devrait étudier de plus près les zones de contact potentiel entre C. gardetta et C. arcania afin de pouvoir exclure une simple isolation par la distance pour expliquer le degré de différenciation qu’on a constaté. Introduction The butterfly taxa Coenonympha gardetta (de Prunner, 1798), C. dar- winiana Staudinger, 1871 and C. arcania (Linnaeus, 1761) are parapatric in the Alps, respectively occupying high (= 1800 m), middle (800- 2000 m), and low (= 1000 m) elevational bands. These taxa have long been seen as closely related (e.g. DAVENPORT, 1941). C. gardetta and C. darwiniana have contact areas where they are reported to intergrade in the southern Alps (Lepidopterologische Arbeitsgruppe der Schweiz, 1987), leading to questions about their taxonomic status as separate species. Because C. arcania is also parapatric, and darwiniana is some- times listed in its synonomy (e.g. FORSTER & WOHLFAHRT, 1976), it is legitimate to question the relationships among all three taxa. In this study, we examine three populations at the contact zone be- tween Coenonympha gardetta and C. darwiniana, and a geographically distant population of C. arcania. If there is indeed partial (or complete) genetic isolation between these taxa, as the current taxonomy suggests, then our contact populations should contain an excess of “pure” forms of each taxon, and few intermediates. Upon closer statistical exami- nation, suites of diagnostic wing pattern and/or allozyme traits would appear to be correlated within individuals in these populations. How- ever, if the major diagnostic differences between these taxa are produced by environmental conditions operating on a common genotypic array rather than by genetic differences maintained by “reproductive” barriers, then there should be no such correlations within contact populations. A similar lack of correlation would result in contact areas if hybrids between immigrants from taxonomically differentiated regional popu- lations were not at a selective disadvantage relative to “pure” individuals. Furthermore, for traits inherited in a co-dominant Mendelian fashion 156 (allozymes in this study), such correlations can also be expressed in the form of F-statistics (WRIGHT, 1969). These have the advantage of permitting us to enlist the analytical power of evolutionary theory to make inferences about underlying populational processes, in particular gene exchange among populations. Of course, it is gene exchange be- tween putative taxonomic groupings that we wish to infer in the process of making taxonomic decisions. Taxonomists have traditionally done this “by eye” and therefore less reliably, especially for the traits whose genetic bases are unknown. Methods Mixed populations of Coenonympha gardetta and C. darwiniana were sampled in July 1991 in the vicinity of Bellwald, Switzerland, on the north slope of Canton Valais in the Rhone Valley. Population I was collected on a steep, SW-facing slope at 1700m in a meadow under an open-canopy fir forest on 13.vu.1991. Population II was sampled also at 1700 m, but 1 km N on a NW-facing, colder slope, locally above treeline, on 20.vii.1991. Population III was at 2000 m at the top of the ski lift, above the treeline in open meadow, on 21.vii.1991. The C. arcania population was collected at 1400 m from Monte Motta- rone, near Streza, Italy, on 23.vu.1991. Individuals were haphazardly netted and stored alive under refrigeration until they could be frozen at -80C. Wing pattern morphometrics The taxonomic literature (DAVENPORT, 1941 ; HicGins & HARGREAVES, 1991; Lepidopterologische Arbeitsgruppe der Schweiz, 1987) was consulted to determine the wing pattern elements previously used to distinguish the three taxa, especially between the more similar taxa, gardetta and darwiniana. The characters proved to be mainly the size and location (relative to the wing margin) of the eyespots in the distal wing cells of the ventral hindwing, and the extent and location of the white band proximal to these spots. Spots near the apex of the ventral forewing have also been used. Wings were removed and stored separately when specimens were pre- pared for electrophoresis (described below). We measured the following characters for each of eight ventral hindwing cells, along the axis of the cell : the diameter of the black center of the eyespot (absent = 0), the distance from the center of the eyespot to the wing margin (absent = unscored), the width of the white band measured to the edge 157 of the eyespot halo (absent = 0), and the edge of the white band to the edge of the wing (absent = unscored). We also measured the diameter of the forewing eyespots (absent = 0). We did not record from the outer wing spot rings because yellow outer rings could not be consistently distinguished when the ground colour was pale ; our scoring system thus regarded any all-yellow spots as being absent. Wing length was measured as an index of body size, and gender was recorded. The left wings were used except when one or more characters was missing due to damage, whereupon the right wings were used. Measure- ments were made at 20x magnification on a colour video monitor using a computerised image-analysıs system. A Wild® microscope was fitted with a Sony® video camera ; this was connected to IBM PC® computer operated using the image-analysis program Optimas® (v. 3.01, BioScan, Inc.). Data collection was mechanised using a macro written in the Optimas procedural language, and measurements were saved directly to a file. We avoided characters involving colour because they were not amenable to accurate measurement using this software. We analyzed the wing patterns using principal component analysis. This method condenses the large number of measurements per individual into a more manageable number of statistically independent characters, and is justifiable both statistically and biologically. The premise, statistically, is that some characters are likely to be correlated, where- upon they carry redundant information and should be weighted to take this into account. For example, large individuals are likely have larger measurements, and we should factor out the body size differences before we attempt to consider relative eyespot size differences. Bio- logically, the premise is that if the taxa are genetically isolated, then their wing patterns will have evolved independently in the separate lineages, and different pattern elements will be correlated, within lineages. The elements that are correlated would form the set of dia- gnostic characters useful for distinguishing the lineages. If genetic isolation were indeed involved, a small number of principal components would contain all the correlated diagnostic characters and describe most of the overall wing pattern variation among individuals, even within contact areas. But if the taxa were freely interbreeding, then characters in contact areas would tend to be assorted independently among individuals ; they would be uncorrelated. Statistically, this would be indicated if the overall wing pattern variation were spread among a larger number of principal components, evidence of independence among the wing pattern elements, and by unimodal variation along principal component axes. 158 Principal components analysis is, in its philosophy, what the experienced taxonomists of older generations did “by eye”. The advantages of the statistical approach are three. Firstly, it is explicit, thus repeatable by others and carries known data limitations. Secondly, it is grounded in statistical theory so it takes sample size into account in a way that cannot be done properly otherwise. Finally, it can pick out much more subtle patterns than can the eye of an experienced worker, and con- versely, it can demonstrate that some patterns perceived by less ex- perienced eyes are fantasy. However, both approaches depend on the ability to pick out the “right” characters to measure, those that will give the best discrimination ; this is why, for characters in this study, we relied on the literature for the acknowledged expertise of previous workers. We used Systat® (v.5.1, Systat Inc.) software on a Macintosh computer for the principal components analysis. We used a Pearson’s r correlation matrix of the 28 primary measurements/individual to generate all principal components (PCs) ; gender and body size were included in these analyses as controls. The statistics require data sets without missing entries, so we were forced to omit the measures of spot or white line location for some wing cells if any individuals were absent that trait (the rejected alternative was to eliminate those individuals). We examined the loadings of characters onto each PC for suites of diagnostic characters. The proportion of the total wing pattern variance explained by each PC was used as an estimate of the overall in- dependence of traits. We then analyzed the corresponding PC scores of each individual (1.e., the “measurement” of the individual along the PC axis, produced as a weighted combination of the original measure- ments in that individual) using one-way ANOVAs for to find significant variation among populations, using SuperANOVA® (v4.0; Abacus Concepts, Inc.) software on a Macintosh computer. The entire analysis was repeated without the C. arcania population to look more closely at differentiation in the Bellwald region ; here we could use a larger data set because fewer individuals were absent the eyespots or white lines in cells. Electrophoresis Horizontal starch gel electrophoresis was performed on head and thorax tissue using standard methods described elsewhere (PORTER & GEIGER, 1988; PORTER & MATOON, 1989). We scored 19 putative genetic loci: alcohol dehydrogenase (ADH; enzyme commission number 1.1.1.1), adenylate kinase (AK-1 ; 2.7.4.7), aldolase (ALDO ; 159 4.1.2.13), esterase (EST-1 ; 3.1.1.1), fumarase (FUM ; 4.2.1.2), glutamic- oxaloacetic transaminase (GOT-1, GOT-2 ; 2.6.1.1), glyceraldehyde-3- phosphate dehydrogenase (GAPDH; 1.2.1.12), a-glycerophosphate dehydrogenase (aGPDH ; 1.1.1.8), hexokinase (HK ; 2.7.1.1), isocitric dehydrogenase (IDH-1; 1.1.1.42), lactic dehydrogenase (LDH; 1.1.1.27), malic dehydrogenase (MDH-1, MDH-2; 1.1.1.37) , malic enzyme (ME-1, ME-2 ; 1.1.1.40), peptidase (PEP-1 ; 3.4.1.1), phospho- glucomutase (PGM ; 2.7.5.1) and phosphoglucose isomerase (PGI ; 38.1.9)! We calculated standard statistics describing the extent of allozyme varia- bility within populations. These include the mean number of alleles observed per locus, the mean heterozygosity observed per locus (H,,,) and that expected based on Hardy-Weinberg expectation (H,,,), and the percent of sampled loci that were polymorphic in the population (%P). We describe variation among populations in two ways. First, we cal- culated Nei’s unbiased genetic distance and produced a summary phenogram using UPGMA. This method is probably most familiar and permits comparison across a wide range of taxa. We also estimated Fsr (WRIGHT, 1969) among the Bellwald populations using WEIR & COCKERHAM’S (1984) method which accounts for sampling variation. We used weighted averaging over alleles and loci, and jackknifed over loci for the error estimates. Our estimates were interpreted using the relationship M = (1/Fsr-1)/4, where M is a gene flow parameter de- scribing the effective number of individuals moving among popula- tions each generation (COCKERHAM & WEIR, 1993). A fundamental result in theoretical population genetics is that when M > 0.5, then gene flow produces substantial genetic similarity among populations at neutral loci (WRIGHT, 1931). We will not provide the theoretical and statistical details here ; interested readers may consult population genetic texts (e.g. HARTL & CLARK, 1989) for introductory concepts, CocKERHAM & WEIR (1993) and references therein for current statistical theory, and PORTER (1990) and PORTER & GEIGER (1988 ; 1995) for examples of applications to butterfly populations. Results Wing pattern morphometrics Coefficients of variation (c.v.) for each trait are shown for each popu- lation and for all populations combined (Table 1). A c.v. of 0.1 means that the standard deviation is 10% of the mean for the trait, a reasonably 160 Table 1 Coefficients of variation for the ventral wing pattern characters used in this study.

Variability is high in the wing pattern traits taxonomists have identified as important, being generally higher than c.v. — 0.2, and is comparable among populations. Some traits, par- ticularly those present in only a few individuals, showed c.v. > 1, an extreme level of variability. This included pattern elements in hindwing cells 7 and 8, and in the forewing spots. 161 First consider variation in all populations. Eigenvalues and the propor- tion of total variance explained by the first ten PCs are in Table 2. The character loadings of the first six PCs are given in Table 3. PC 1 loaded highly for most characters, especially for forewing length, and we interpret it as a general body size character. Note that several traits did not load here, indicating that these varied relatively independently of body size (this points out the hazards of an alternative approach : dividing all measurements by body size for standardisation before statistical analysis). These include the spot diameter in cell 6 and the white line width in cell 1. PC 2 describes an inverse ratio of spot diameter and white line width, and is largely independent of body size. PC 3 mainly describes the shape of the white line as it traverses the cells, with loadings being positive in the first cells and negative in the later cells ; the spot diameters in cells 2 and 6 and the width in cell 2 also load here. This PC captures a previously reported taxonomic difference between arcania, with a line that narrows posteriorly, and the others, with a line of relatively constant width. PCs 4 and 5 describe subtle relationships between spot diameters, white line widths and their locations in several cells. PC 6 describes sexual dimorphism, and characters that also load here include the spot diameter of cell 6 and the white line width in cell 8.

The Mottarone population (arcania) differed from the others in PC 3 (ANOVA ; F3 7) = 17.164 ; P < 0.0001), indicating a difference in white line shape between these groups (Figure 1b). PC 6 also showed significance (ANOVA ; F37 = 3.233 ; P= 0.027), but we attribute this to a difference in sex ratios among populations. These differences demonstrate that the arcania population is phenotypically different from the remaining po- pulations, and by themselves, suggest a possibility of genetic isolation. Means of PCs 2, 4 & 5 were not significantly different among po- pulations, and we consider them to represent patterns of variation common to all populations. The differences between arcania vs. Bellwald populations could poten- tially obscure more subtle differentiation between gardetta and dar- winiana in the contact zone, so it is appropriate to reanalyze the data dropping the Mottarone population. 163 1.5 PC 1 -1 Bellwald | Bellwald Il Bellwald Ill Mt.

Eigenvalues of the first ten PCs and the percent of the total variance explained PC Eigenvalue % variance explained © \O 00 I A Un BR © ND — Here we concentrate on the gardetta/darwiniana sampling sites at Bellwald, excluding arcania. Eigenvalues and the proportion of total variance explained by the first ten PCs are in Table 4. The character loadings of the first six PCs are given in Table 5; it is important to remember that these PCs describe different combinations of characters than those in the previous analysis. PC 1 again loaded highly for most characters, especially for forewing length, and we interpret it again as a general body size character. The forewing spot diameter and the several of the white line widths vary little with body size, nor is there sexual size dimorphism. PC 2 shows strong negative loadings for white line width and weak positive loadings for spot diameters. We interpret it as a white line width parameter that is in relative agreement with a diagnostic character often used to separate gardetta and darwiniana. PC 3 describes a differentiation pattern in inter-cell ratios of spot and white line sizes — at one extreme are darwiniana-like individuals with the middle cells having relatively smaller spots and extreme cells having wider lines, at the other are individuals with the reverse. PC 4 describes sexual dimorphism, with hindwing spot 6 being larger in males and the white band slightly more centrally located in females. PCs 5 & 6 describe mainly relationships among spot sizes. We found significant differences among populations only in PC 4 (ANOVA ; F357 = 5.093 ; P = 0.009), and this was attributed to the different sex ratios of these population samples. The difference in body size from the previous analysis was not quite significant here (ANOVA ; F; 57 = 2.736 ; P = 0.073). Distributions for all three Bellwald popu- lations along PC axes 2 & 3 are shown in Figure 2 ; these axes describe 165 Table 5 Loadings for the first six PCs for the gardetta-darwiniana contact area only gender forewing length forewing spot diameter 2 hindwing spot diameter OU B © N = white line width O0 I ON Un BB © ND = 5 = ndwing spot location U 8 © ND white line location Un © ND most of the gardetta-darwiniana diagnostic characters. Despite the numerous individuals that appear to have gardetta and darwiniana characteristics, there is unimodal variation and no evidence from wing pattern that these taxa are genetically isolated. Allozyme differentiation Allelic frequencies for variable loci are given in Table 6. The loci EST-1, GAPDH and aGPDH were monomorphic. Summary statistics de- scribing genetic variability within populations is given in Table 7. Varia- bility is remarkably high, a common phenomenon in butterfly popu- lations, including Coenonympha (PORTER & GEIGER, 1988 ; PORTER & MAToon, 1989), and indicates that these populations are quite large and have not been through population bottlenecks in their recent past. 166 darwiniana om O jae 3 D QG O 5 -4 -3 -2 -1 0 1 2 ardetta darwiniana @ PC 2 Fig. 2. Distributions of individuals from the Bellwald populations along PC axes 2 & 3 are unimodal. 1 — from Bellwald I; 2 — Bellwald II; 3 — Bellwald III. PCs are standardised to have their means at zero and scale in units of standard deviations. The populations do not differ significantly along either axis. Differentiation among populations is described graphically using a distance Wagner procedure (FARRIS, 1972) on a matrix of pairwise RoGers’ (1972) genetic distances (Figure 3a), and using UPGMA cluster analysis on a matrix of Ner’s (1978) unbiased genetic identities (Figure 3b). The Mottarone arcania population segregates from the others, at a level suggesting that it may be genetically isolated. The remainder cluster closely, at levels commonly observed among con- specific populations in other butterfly taxa. The high similarity within the Bellwald group permits closer popu- lational analyses using F-statistics. Within the Bellwald population group, we obtained an estimate of 9 (= sr) = - 0.00223 + 0.00127 (s.d.), averaged over alleles and loci. This slightly negative value is a result of sampling error and shows that 0 is not significantly different from zero, indicating that there is no appreciable genetic differentiation among sites. This is perhaps more easily understood when translated to a gene flow estimate (M) using M = (1/0 — 1)/4, yielding a value of 942 < M S panmictic (95% c.i.). This large number of individuals exchanged among sites each generation suggests that the sampled “populations” are effectively sub-sites within a single, larger panmictic population in the Bellwald area. 167 Table 6 Allele frequencies for variable loci, by population.

The morphometric analyses isolated essentially the same suites of “diagnostic” character states that taxonomists have used, showing that the results are not spurious as has been suggested in similar studies (HAMMOND, 1985). Neither is the high genetic similarity a spurious result of low variability : genetic variability is high enough that if two species have been coexisting at Bellwald, then genetic drift should have already differentiated the populations (see PORTER & GEIGER, 1995 for a discussion of this effect). There is no evidence to suggest that these are distinct species at Bellwald. The C. gardetta-darwiniana contact region is similar to contact regions between C. tullia (Müller, 1764) taxa in western North America. C. tullia-group taxa in California, Nevada and Oregon differ in eyespot size and number, dorsal and ventral ground colour and the shape and placement of the white lines, and were distributed among several no- minal species. However, populations are highly variable, and taxono- mists, with the notable exception of DAVENPORT (1941), had tended concentrate on widely separated localities, ignoring contact areas and intrapopulational variability. When contact areas were examined, and allozyme data used as corroborating evidence, it was found that wing patterns intergraded, gene flow was high, and no genetic isolation was apparent (PORTER & GEIGER, 1988). Instead, the geographic variation in wing pattern was attributed to unknown selective and/or historical factors, being maintained in the face of strong gene flow between the taxonomically recognised forms. In one remarkable example, a popu- lation on coastal dunes was sharply differentiated in wing pattern from one only 8 km away on a hilltop, yet the allozyme data could only be reasonably interpreted as showing evidence of strong gene flow between them (PORTER & MATOON, 1989). The allozyme data indicate that the C. gardetta-darwiniana population at Bellwald is probably quite large and demographically continuous over an area of several km?. This area encompasses the respectively “typical” subalpine and alpine habitats of C. darwiniana and C. gar- detta, and is consistent with the interpretation that no genetic isola- tion exists between them. The implication is that individuals are quite mobile, readily moving distances of 2 km or more in their lifetimes. Whereas this should obviously be verified with a demographic study, we point out that marked C. tullia california Westwood, 1851 in Cali- 170 fornia have been recaptured at distances >1 km (WEISSMAN, 1972), and stray individuals have been seen in the Central Valley (Davis area) at least 40 km from potential source populations (SHAPIRO, 1982 ; PorTER, pers. obs.). We believe C. gardetta and C. darwiniana should be considered con- specific and the younger name, darwiniana, be placed in synonymy. This decision is based on the high genetic and phenotypic variability in the contact zone without apparent isolation, and remains subjective pending verification by closer demographic studies there. However, the patterns are strongly suggestive, and the onus now properly belongs on a splitter to demonstrate that C. gardetta and C. darwiniana are genetically isolated, rather than being extremes of a cline as we be- lieve they are. Indeed, the high gene flow estimate would argue that darwiniana not even be used as a subspecies name, because indivi- duals from populations of “darwiniana” wing phenotype are likely to be much more closely related in pedigree to those from “gardetta” populations directly upslope than to butterflies from populations with “darwiniana” phenotypes at more distant localities. A minor difference between C. gardetta and darwiniana in the male genitalia has been identified (Hıscıns, 1975), but DAVENPORT (1941) found the genitalia to be quite variable. Regardless of the validity of this putative difference, small differences in the genitalia per se have little value as evidence of reproductive isolation between parapatric taxa (PORTER & SHAPIRO, 1990). The possibility also remains that C. arcania and C. gardetta (+ dar- winiana) are conspecific, as we have only studied widely separated populations and these taxa too may intergrade in their contact areas. However, both the allozyme and wing pattern differentiation in our limited data are consistent with differences between closely related sympatric taxa, and we believe their continued designation as species — the status quo — is appropriate pending publication of studies done in contact areas. Anticipated results from a current study of the C. arcania group, on a larger geographic scale than ours (WIEMERS, 1994), will bring us much closer to the solution of this problem. Systematists of Coenonympha have long relied heavily on qualitatively described wing pattern dimensions as characters, even while lamenting their intra- and interpopulational variability (DAVENPORT, 1941). Species-level taxonomic decisions in Coenonympha could be greatly illuminated if we understood more about how wing pattern is develop- mentally, genetically and ecologically controlled, because it would help us determine the extent to which character variation could be used 171 as markers for more profound genetic differentiation. Studies of the wing patterns of Coenonympha indicate that several taxa have clines in spot pattern, with spot size diminishing with increasing elevation (BRUNTON et al., 1991) or latitude (K. PORTER, 1980 ; DENNIS et al., 1986) ; these patterns also appear to occur in North American C. tullia but have not yet been studied quantitatively. Though the eyespots of the Nymphalidae are probably serially homologous (NisHout, 1991), multivariate statistical analyses have demonstrated that the pattern elements in different wing cells are largely developmentally independent (NuHouT, 1985 ; Dennis et al., 1984). Dennis et al., (1986) proposed that geographic variation in spot size in C. tullia is attributable to parallel variation in selection pressures imposed by different suites of predators or predator abilities relative to gross habitat type. The alter- native that one might infer from clinal variation, that spot pattern is not genetically controlled at all, seems unlikely given the weaknes- ses of correlations of spot sizes within individuals and the heritability of spot pattern in other Satyrinae (BRAKEFIELD & NOoORDWIK, 1985). It would also be difficult to credibly explain, without invoking adap- tive genetic differences, why spot size gets smaller with increasing ele- vation in C. gardetta, but larger with increasing elevation in C. corinna and North American C. tullia, even though the ecological causes of these putative adaptations remain elusive. This is not to exclude an important role for environmental effects : polyphenism is apparent in several satyrine taxa, e.g. Bicyclus (BRAKEFIELD & REITSMA, 1991) and C. tullia (WEISSMAN, 1972), indicating the presence of genotype by environment interactions in the control of wing pattern. Though C. arcania and C. gardetta usually have only a single annual generation, similar underlying genetic mechanisms could well be influencing their wing patterns. Unfortunately, there are substantial technical difficulties to surmount before these issues can be quantitatively studied in Coeno- nympha and, especially, before they can be used to truly test assumptions underlying species-level taxonomic decisions.

S. Smirx* & Denis F. OWEN** * Natural History Museum, Eton College, Windsor, Berkshire SL4 6EW, England ** School of Biological and Molecular Sciences, Oxford Brookes University, Headington, Oxford OX3 OBP, England (!) Summary Samples of the endemic Canary grayling butterfly, Hipparchia (Pseudoter- gumia) wyssü (Christ, 1889), were obtained from all five of the Canary Islands where it occurs. Each island population comprises a distinct subspecies but the differences between them are quantitative rather than qualitative ; hence a system 1s devised by which elements of the wing pattern are scored to permit quantitative analysis. The results demonstrate significant inter-island differences in Wing size and wing pattern. The underside of the hindwing shows the greatest degree of inter-island variation. This is the only wing surface that is always visible in a resting butterfly ; its coloration is highly cryptic and it is suggested that the pattern was evolved in response to selection by predators long before H. wyssü or its ancestors reached the Canaries. Subsequent evolution of the details of the wing pattern differed from island to island because each island population was probably founded by few individuals with only a fraction of the genetic diversity of the species. It is postulated that the basic “grayling” wing pattern is determined by natural selection, but the precise expression of this pattern on each island is circumscribed by the limited gene pool of the original founders. Resume Des exemplaires du Satyride Hipparchia (Pseudotergumia) wyssii (Christ, 1889), endémique des Iles Canaries, ont été récoltés dans les cinq îles de cet archipel où ils existent. Les populations de chaque île forment une sous-espèce distincte, mais les différences entre celles-ci sont plutôt quantitatives que qualitatives. On a donc établi un système basé sur certains éléments précis des ailes permettant une analyse quantitative. Les résultats ainsi obtenus prou- vent l’existence de différences significatives entre les populations de chaque (1) Address for correspondence. 13 île en ce qui concerne la taille et le dessin des ailes. Le dessous des ailes posté- rieures est l'élément qui présente le plus fort degré de variation d’une île a l’autre. C’est en fait la seule partie de la surface des ailes qui est visible lorsque le papillon se pose. Son homochromie extrême est un élément de camouflage par mimétisme. On peut envisager que ce dessin a évolué du fait de la sélection par les prédateurs longtemps avant que A. wyssii ou ses ancêtres aient atteint les Canaries. L'évolution ultérieure des détails dans ce dessin des ailes fut différente d’une île à l’autre parce que la population de chaque île avait pro- bablement été fondée par un petit nombre d’individus qui n'étaient chacun porteurs que d’une fraction de la diversité génétique de l’espèce. On peut donc penser que si le dessin typique «Hipparchia» du dessous des ailes postérieures est déterminé par sélection naturelle, la réalisation concrète de ce dessin sur chaque île se trouve différenciée du fait du stock de gènes incomplet des premiers arrivés «fondateurs». Zusammenfassung Der Augenfalter Hipparchia (Pseudotergumia) wyssii (Christ, 1889) ist auf den Kanaren endemisch. Untersuchungen an Material von allen fünf Inseln des Archipels, auf denen die Art vorkommt, ergaben, daß jede Inselpopulation eine eigenständige Unterart darstellt, die sich aber eher quantitativ als qualitativ von den anderen unterscheidet. Daher wurde ein System entwickelt, das durch die Untersuchung von Flügel-Zeichnungselementen eine quantitative Analyse erlaubt. Die Ergebnisse zeigen signifikante Unterschiede in Flügelgröße und Flügelzeichnung zwischen den Inselpopulationen. Die größte Variabilität weist die Unterseite des Hinterflügels auf. Dies ist die einzige Flügelfläche, die an einem ruhenden Falter stets sichtbar ist. Sie zeigt eine ausgeprägte Tarnfarbe, deren Muster vermutlich durch Feinddruck selektiert worden ist, bevor A. wyssii oder ihre Vorfahren die Kanaren erreichten. Die spätere Entwicklung der Details der Flügelzeichnung variiert von Insel zu Insel, weil jede Inselpopulation wahrscheinlich nur von wenigen Individuen -mit nur einen Bruchteil der gene- tischen Vielfalt der Art -begründet wurde. Es wird postuliert, daß das grund- legende Hipparchia-Flügelmuster durch natürliche Selektion bestimmt wird, aber die genaue Ausprägung dieses Musters auf jeder Insel vom begrenzten Genpool der ursprünglichen Gründer abhängt. Introduction The Canary grayling butterfly, Hipparchia (Pseudotergumia) wyssii (Christ, 1889) (Lepidoptera, Satyrinae) is endemic to the five Canary Islands of Tenerife, La Gomera, Gran Canaria, La Palma and El Hierro (Fig. 1). Until recently little was known of this species and even its presence on one island, La Palma, was in doubt (LEESTMANS, 1975) ; however a comprehensive review which followed several collecting trips (WIEMERS, 1991) has established that the butterfly is relatively common 176 0 Lanzarote 3 Canary Islands Tenerife Ga wyssii La Palma“ = Fuerteventura tilosi La gomera Gran Canaria gomera tamadabae El Hierro bacchus Fig. 1. The Canary Islands showing the distribution of the five subspecies of Hipparchia wyssü. on Tenerife, La Gomera, La Palma and El Hierro (Herr Wiemers did not collect on Gran Canaria), and absent from the two eastern islands of Fuerteventura and Lanzarote, both of which are too dry for grass- feeding satyrine butterflies. This paper presents the results of our own sampling and field work on all five islands over the period 1987-91. Grayling butterflies have a complex wing pattern, particularly on the underside, and the variation is difficult to quantify. Here we identify scorable and quantifiable phenotypic variation in wing pattern and coloration and use this to estimate the extent to which each island population is differentiated. Our paper is complementary to two previous analyses of variation in Canary Island satyrine butterflies : Maniola jurtina (Linnaeus, 1758) (OWEN & SMITH, 1990) and Pararge xiphioides Staudinger, 1871 (OWEN & SMITH, 1993). The island populations Each island population is distinctive and we treat each as a subspecies ; in contrast WIEMERS (1991) recognizes four species : A. wyssii (Tenerife and Gran Canaria), H. gomera (La Gomera), H. bacchus (El Hierro) jig! and A. tilosi (La Palma). We recognize five subspecies, one on each island while agreeing that some or all of them may have diverged sufficiently to be designated as species ; as we discuss later, there is rarely conclusive evidence either way (from crossing) when dealing with allopatric populations and, in its absence, splitting should be avoided (CoRBET & PENDLEBURY, 1992). Plates 1 and 2 show the complex but distinctive underside patterns of males and females of each of the five subspecies. H. wyssii wyssii (Christ, 1890). Tenerife. Mostly confined to Pinus canariensis forest at altitudes of 1300 — 1700 m and also found above the pine forest zone to 2300 m at Las Cañadas. H. wyssii gomera (Higgins, 1967). La Gomera. Widespread in open country and light woodland at 300 — 1200 m. (There is no natural pine forest on La Gomera.) H. wyssii tamadabae Owen & Smith, 1992. Gran Canaria. Mainly in P. canariensis forest at 300 — 500 m but extending to 1800 m and especially associated with shallow barrancos. Known chiefly from the north-west of the island. H. wyssii bacchus (Higgins, 1967). El Hierro. Strongly associated with vineyards in barrancos at 300 — 700 m and extending in small numbers to 1500 m in laurel forest, but apparently rare or absent in P canariensis forest. H. wyssii tilosi Manil, 1984. La Palma. Apparently widespread in deep and steep-sided barrancos above 500 m in mixed laurel/ pine forest on the east and north-east side of the island, but probably absent from the extensive P canariensis forest around the Caldera de Taburiente. This subspecies may be much more split up into relatively isolated populations than the others. On all islands the butterflies are on the wing in July and August but can occur as early as May and as late as September. The early stages from four islands are described in WIEMERS (1991). The larvae are grass-feeders but precisely which species of grass are utilized in the wild has not been determined. There is one breeding generation a year. Adult butterflies occasionally visit flowers but are more often seen visiting damp patches and ripe fruit, especially grapes; on Gran Canaria, and probably also on Tenerife, they probe cracks in the bark for pine resin. On Tenerife and Gran Canaria in particular there is a marked downhill movement in the evening and an uphill movement in the morning. Most individuals involved are females. This behaviour is spectacular, especially in places where movement is funnelled by a 178 dry barranco ; we have no explanation for it but suggest it may be associated with locating egg-laying sites or with diurnal temperature changes. The cryptic coloration of the underside, especially of the hindwing, is superb. When at rest on a pine trunk with the forewing lowered, a butterfly is almost impossible to see. When a resting butterfly is approached it raises its forewings and exposes the eyespots and at first walks around the tree trunk, sometimes circling the trunk several times. This is presumed to be anti-predator behaviour but we have no observations of successful predation, only an attempted catch by a blue tit, Parus caeruleus Linnaeus, 1758, and two unsuccessful strikes by a large asiliid fly. Some of the butterflies in our samples have wing damage suggestive of unsuccessful attacks by lızards. The existence of H. wyssii on four of the Canary Islands has been known since 1888-9 (review in WIEMERS, 1991) but until 1966 it was well-known only from Tenerife, where it has been taken repeatedly. The rediscovery of populations on La Gomera and El Hierro in 1966 by Guichard and Ward (GuICHARD, 1967) was considered “unexpected and exciting...No butterflies of such distinctive appearance have been discovered in the Western Palaearctic Region for very many years” (Hıscıns, 1967). (Higgins was apparently unaware of earlier records for both islands dating from 1889 (REBEL & ROGENHOFER, 1894) and of NORDMAN (1935) for La Gomera.) The La Palma population re- mained unknown until 1983 (MANIL, 1984), possibly because its habitat is sO inaccessible, while the true habitat and status of the Gran Canaria population seems to have been unknown until we discovered it in 1990 (OWEN & SMITH, 1992 and this paper). Source of samples and methods of scoring In 1987-91 we visited all the islands where A. wyssii occurs and collected random samples, from single locations in the case of four islands and from six different and isolated populations, four of which are new records for the species, on La Palma. Samples were deliberately limited because of uncertainty as to exactly how common the species is on each island ; in the event we discovered that no island population is endangered except by habitat destruction resulting from increased cultivation. The butterflies were pinned and set for more detailed examination. Sample sizes for each island are given in Table 1. Fig. 2 is a diagram of grayling wings showing the numbering system for space(s) where spots (border ocelli) may be present or absent ; it 179 Table 1 Inter-island variation for forewing length (mm) in 7. wyssii in the Canary Islands Island abbreviations : T = Tenerife, G = La Gomera, C = Gran Canaria, P = La Palma, H = El Hierro. * One very small and otherwise aberrant female (22.8 mm), much the smallest individual of either sex recorded, substantially reduces the mean of this sample, without which it is 30.3 mm (n = 8). basal discal postdiscal submarginal Fig. 2.

Each butterfly was examined by eye using a X 2 lens. All the scoring was done by one of us (DASS) to ensure consistency. The characters scored are listed in Appendix I. Forewing length was measured (with vernier calipers to an accuracy of 0.1 mm) from the apex to the point where the basal area joins the thorax. It was possible to measure forewing length in every specimen collected but for some other characters not all specimens could be scored because of damage. Analysis Size Table 1 shows the mean forewing lengths for males and females. The rank order of forewing length for males is El Hierro > La Palma > La Gomera > Tenerife > Gran Canaria. If the single aberrant female from La Palma is omitted (Table 1), the rank order of forewing length for females is similar : El Hierro > La Gomera > La Palma > Tenerife > Gran Canaria. Table 2 shows the results of a one-way ANOVA for forewing length. The overall values of variance ratios (F) are significant for both males and females at the 0.1 per cent level, indicating that forewing length (which reflects body size) has diverged significantly among the island populations. Individual island comparisons are shown in Table 2 only where they are significant.

Therefore, size may be a diagnostic character for at least these two islands but it is possible that larger samples would reveal that all five populations are statistically different in size. The marked difference in size between Gran Canaria and El Hierro butterflies can be seen in Plates 1 and 2.

Spot 5 is always black and may be white-pupilled (underlined) or ringed with a yellowish halo (super- script bar). Table 3 shows the distribution of hindwing spotting phenotypes on each of the five islands. As shown, we recorded 18 upperside (UPH) pheno- types (A-R), and 22 underside hindwing (UNH) phenotypes (1-22). 183 Table 3 Distribution of the hindwing upper and underside border ocellus phenotypes of H. wyssii (see Appendix III for codes) on the five Canary Islands where it occurs | Phenotype |T|G|C|H| P| Phenotype |T|G|C|H|P| Phenotype |T|G|C|H|P| T | Phenotype |T|G|C|H| P| Phenotype |T|G|C|H] P| Phenotype |T|G|C|H] P| C|H| P| Phenotype | T|G|C|H| P| Phenotype | T|G|C|H|P + + - + + + + + - -- + + ar r - + -- + + + +|+]+]+ + + 4 +\+] |+/+ +) + + + + +) [+ + - + +++ + ++ + + + + + A a § recorded in males only (19), * recorded in females only (28), # recorded in both sexes (11). Island abbreviations as in Table 1. 58 different combinations were recorded ; the theoretical maximum is 396 though the actual number is probably far less. Considering the small size of some samples, however, many more phenotypes would be expected in larger samples, especially in males from Tenerife (n = 3) and females from La Gomera (n = 3). Nineteen phenotypes occur in males only, 28 in females only and 11 in both sexes : females are thus more variable than males. Table 4 summarizes inter-island differences in the distribution of hind- wing phenotypes and compares hindwing diversity on each of the five islands. Of the 58 hindwing phenotypes recorded only 12 (= 20%) occur on more than one island, none is found on all five islands and only three (= 5%) occur on four islands. This alone suggests considerable inter-island diversification. The distance coefficients for phenotypes shared with other islands (Table 6D) show that La Palma has the most distinct population, followed by Gran Canaria, Tenerife and La Gomera/El Hierro.

Palma is also the most distinctive population in terms of the percentage of unique phenotypes, followed again by Gran Canaria and Tenerife. Small sample size in one or the other sex from some ıslands necessitates combining sexes to estimate phenotypic diversity. Although this pro- cedure inevitably involves the loss of some resolving power, the results are nevertheless unambiguous. We use two contrasting measures of diversity, the Margalef Index and the Berger-Parker Index (MAGGURAN, 1988). The former is primarily a measure of richness (number of pheno- types) (CLIFFORD & STEPHENSON, 1975) and has the disadvantage that it is strongly influenced by sample size (SOUTHwoo»p, 1978) ; the latter emphasises evenness (or dominance) and is little affected by sample size (MAY, 1975). In this case, where all samples are fairly small, the Berger-Parker Index is preferred although encouragingly the rankings for the two indices are in substantial agreement. The La Palma (Berger- Parker) and Gran Canaria (Margalef) populations have the highest diversity, El Hierro and La Gomera (especially) the lowest, with Tene- rife intermediate (both indices agree on the ranking of the latter three islands). In general the larger islands (Tenerife, Gran Canaria and La Palma) are more diverse than the smaller (El Hierro and La Gomera), as could be predicted from biogeographical theory (MACARTHUR & WILSON, 1967). The high diversity on La Palma, in particular, is enigmatic : it may result from independent evolution of sub-populations in relative isolation within deep barrancos, a situation which probably does not prevail on the other islands. 185 Table 5 Mean values for spots, pupils and halos comprising the hindwing border ocellus system in H. wyssii from the Canary Islands land i Pool PS al 2 iP ni won UPH spot average (max. 5) UNH spot average (max. 5) Pupil average (max. 6) Halo average (max. 6) N (N*) UPH spot average (max. 5) UNH spot average (max. 5) Pupil average (max. 6) Halo average (max. 6) N (NX) * Numbers in parenthesis are sample sizes for spot averages reduced due to hindwing damage in some specimens. § Sample means significantly different (in ¢ tests) from others in the same row. Island abbreviations as in Table 1. Table 5 shows the UPH and UNH spot averages for males and fe- males for each island. Correlation for UPH and UNH spot number in individuals is low and not significant in either males (r = 0.070, n = 68) or females (r = 0.073, n = 55) ; NısHouT (1991) has emphasised that dorsal and ventral wing coloration patterns develop from epithelial monolayers within separate compartments and that correlation between them is by no means inevitable. As shown, La Palma has the highest values for spot average for both UPH and UNH. El Hierro and La Gomera have the lowest values with Tenerife and Gran Canaria inter- mediate. The frequency of white pupils in the six black spots (border ocelli) (UPF/UNF s6 and s3 and UPH/UNH s2) and of the yellow halos around the same spots, provides a set of characters additional to hind- wing spotting which can be used to differentiate populations. Table 5 gives pupil and halo averages for males and females for each island. The sum of pupils (maximum 6) and halos (maximum 6) for an 186 individual butterfly gives a measure which we call spot enhancement (maximum 12); both pupils and halos render the black spots more distinctive and conspicuous. Males and females from La Palma and Gran Canaria have significantly higher enhancement values than the other populations but it is obtained by different means : mainly by pupillation on Gran Canaria (a consistently diagnostic feature of ssp. tamadabae) and by the development of halos in ssp. tilosi from La Palma. Both features are recorded from some of the other islands but less distinctly and much less frequently. On La Palma and Gran Ca- naria, the black spots tend to be larger and, when combined with white pupils and yellow halos, they are rendered much more apparent. The ssp. bacchus phenotype is also highly distinctive in a quite different way from ssp. tilosi or ssp. tamadabae, because of the intense contrast between the postdiscal black line (element f of the central symmetry system (NıJHoUT, 1991)) and the band of white background immediately distal to it, especially on the UNH (Plates 1 and 2); ssp. bacchus has low values for spot average and much the lowest development of spot enhancement (Table 5). As the background of the bacchus wing is extensively melanised, several other black pattern elements (d, e and i (NısHout, 1991)) are also relatively obscured. Subspecies gomera is intermediate between ssp. bacchus and ssp. wyssii in all the above respects (Plates 1-2).

Island abbreviations as in Table 1. 187 Phenetic distance coefficients The phenotypes of all members of the genus Hipparchia Fabricius, 1807 are difficult to measure as much of the variation is quantitative and therefore judgment of it subjective. Hence for the calculation of phenetic distance coefficients (Table 6), we have chosen 34 non-metric characters (Appendix I) which are discrete (i.e. can be consistently scored as present or absent) and variable in frequency within or between islands. This statement does not imply that these characters are the only ones by which the five island populations can be compared and differentiated, nor that they are necessarily even the most distinctive. Many characters are manifested only or mainly in males (9) or females (7) ; those which are variable in both sexes (18) nevertheless differ in frequency and so they are scored separately for males and females. Therefore the matrices (Table 6) are based on 27 characters for males, 25 for females and 52 for the combined sexes. As shown in the character matrix (Appendix II), few characters are absolutely diagnostic, most differing only quantitatively between islands. Hence each character score is weighted (0-100%) for its comparative frequency. The data in Table 6 represent the Euclidean distance MED (SNEATH & SOKAL, 1973) between pairs of island populations (OTUs). ED is calculated for each OTU (subspecies) pair using the formula : EDy =[2(X, - Xu)" where X; and X; are the scores of OTUs (subspecies) j and K for character 1. Mean Euclidean distances (WED) over all characters are calculated as : MED, = \[2(X, - Xx)21/n where n is the number of characters. Comparing the distance values (WED) between sexes (Table 6A, B, Fig. 3A, B) it is clear that females have in general diverged further than males. In the case of La Palma this applies to the female MED values compared to all other islands ; for Gran Canaria it is confined mainly to the comparison with Tenerife. Furthermore, the differences between the male and female phenograms (Fig. 3), and the absence of any significant rank correlation between their inter-island phenetic distances (Table 6), strongly suggest that there has been a degree of independence in the evolution of the phenotype of the two sexes, the male being the more conservative . 188 PG, (AY Th 0.2 0.7 3 5 20.3 {1} is 0.8 T _ 5 0.4 D © 2 w 0.9 5 8 0.5 ® > < 0.6 1.0 Fig. 3. Phenograms, derived by UPGMA, showing the mean Euclidean distances (MED) (Table 6) between the five subspecies of Hipparchia wyssü: A, males ; B, females ; C, combined sexes ; D, hindwing border ocellus phenotypes (both sexes) shared between islands (Table 3). Island abbreviations as in Table 1. Considering combined sexes (Table 6C), La Palma (mean distan- ce — 0.523) ıs the most distinctive followed by Gran Canaria (0.468). El Hierro (0.450) is intermediate, with Tenerife and La Gomera (both 0.422) the least distinctive on average. The two most similar populations are El Hierro and La Gomera. However, there is no rank correlation (SIEGEL & CASTELLAN, 1988) between the geographical distances separating islands and phenetic distances (Kendall’s 7 (tau) = 0.422; P=0.11). In Table 6D we compare the islands by numbers of shared hindwing phenotypes. The isolation of La Palma and the closeness of La Gomera and El Hierro are again clear and, as above, there is no rank correlation between the physical distance separating islands and the number of shared phenotypes (t = 0.244 ; P= 0.38). Encouragingly, however, the two methods of inter-island comparison (Table 6C, D) are themselves significantly correlated by rank (t = 0.822 ; P= 0.04). Interpretation of inter-island variation The phenograms in Fig. 3 are derived by the UPGMA method (SNEATH & SoKAL, 1973) from the data in Table 6. The relative isolation of 189 the La Palma subspecies is evident in all the phenograms ; La Gomera and El Hierro form a cluster ; Tenerife and Gran Canaria may also form a cluster, possibly for male phenotypes only (Table 6A, 6C), but 6B and 6D suggest that Tenerife is closer to La Gomera/El Hierro with Gran Canaria more isolated. The raw data for males (Table 6A) indicate that ssp. tilosi (La Palma) is closer to ssp. gomera (La Gomera) than to any other but this is not the case for females. The phenetic distance of ssp. tilosi females from all other subspecies would suggest either a comparatively early dichotomy from the ancestral stock or more recent but rapid evolution. To explain this anomaly it is neces- sary to postulate different rates of evolution in males and females, the former being relatively conservative and the latter evolving rather rapidly, especially on La Palma. All data sets (Table 6) show that ssp. tamadabae (Gran Canaria) is closest to ssp. wyssü (Tenerife). In this case too, however, there is a sex difference, the males being much closer than the females. The El Hierro subspecies (ssp. bacchus) is un- doubtedly closest to ssp. gomera and is equally distinctive, mainly due to the dark background (unscored) (Plates 1 & 2), in both sexes. It should be noted, however, that WIEMERS (1991) observed that the eggs of these two subspecies are quite dissimilar. The origin and relationships of A. wyssü There are three other species belonging to the subgenus Pseudotergu- mia Agenjo, 1947 (KUDRNA, 1977). If examined comparatively in the manner advocated by HARVEY & PAGEL (1991), they are the outgroup for reconstructing ancestral character states. 7. fidia (Linnaeus, 1767) is a west Mediterranean species ranging from Morocco, Algeria and Tunisia through Portugal, Spain and S. France to Italy; A. pisidice Klug, 1832 occurs in the Middle East from Sinai through Jordan, Palestine, Lebanon and Syria to south Turkey ; A. tewfiki (Wiltshire, 1949) is a relict endemic restricted to Yemen and southwest Arabia. All three species share with H. wyssii tamadabae the white pupilling of the two forewing ocelli in s6 and s3 (UPF and UNF). These cha- racters are likely to be primitive for the subgenus and their absence from most individuals of the other subspecies of H. wyssii is probably due to loss. There are several other similarities between ssp. tamadabae and the other Pseudotergumia species (the nomenclature of the fol- lowing pattern elements follows NiJHouT (1991) : first, the bold black proximal band of the central symmetry system (element d), which bisects the discal cell (UNF); second, bold discal spots (element e) on the discoidal vein (UNF) and, third, bold proximal (medial) and 190 distal (postmedial) bands (elements d and f) of the central symmetry system (UNH), given in our original description of ssp. tamadabae (OwEN & SMITH, 1992). All things considered, it seems likely that A. wyssii tamadabae is closest to the ancestral Pseudotergumia (and Hipparchia) phenotype. In other words, the states of some of the above characters in most individuals of H. wyssii ssp. wyssii, gomera, bacchus and rilosi are derived. The origin of H. wyssii itself is a matter for conjecture. On the evidence of present distributions, an origin for H. wyssii from H. fidia stock, which inhabited the western Mediterranean area, seems the most plausible. Indeed, while admitting that Hipparchia phenotypes are in general conservative, the adult phenotype of H. fidia is in many respects close to H. wyssii tamadabae. However, from a comparison of the male genitalia and androconia, KUDRNA (1977) believed H. wyssii to be closer to H. tewfiki than to either A. fidia or H. pisidice. Judging from his excellent figures of the very similar genitalia and androconia of all the Pseudotergumia species, his conclusion requires exceeding- ly fine distinctions to be made, mainly on grounds of size. As is com- monly the case when genitalia characters are used in insect taxonomy, no allowance was made for allometry (GouLD, 1966): H. tewfiki is considerably smaller than all other species of Pseudotergumia but, of the subspecies of H. wyssii examined by Kudrna, is closest in body size to ssp. wyssii (which he believed inhabited both Tenerife and Gran Canaria). The above remarks notwithstanding, as the only worker to have examined all known museum specimens of the four Pseudoter- gumia species, we tentatively accept Kudrna’s conclusion that 7. wyssii is closer to A. tewfiki than to A. fidia. In view of the conservatism of Hipparchia adult phenotypes and the considerable continuous variation between individuals within taxa, a protein or DNA study is needed to reach more robust conclusions. If A. wyssii and A. tewfiki are indeed closely related then their present distributions, in the Canaries and southwest Arabia, respectively, are highly disjunct. To account for the presence of H. wyssii in the Canary Islands, it is therefore necessary to invoke both vicariance and several island-hopping events. We argue that neither is improbable as both are prevalent features of the flora and fauna of the Canary Islands. First, during the Miocene, southern Europe and the present Sahara Desert area were covered with subtropical to tropical evergreen forests (AXELROD, 1986). As drier climates spread through the Upper Miocene and Pliocene, disjunctions in range developed, which are well-docu- mented for the flora (BRAMWELL, 1976) resulting in highly disjunct Fall distributions between, on the one hand, the Canary Islands and, on the other, far-distant locations such as Arabia, Socotra, Mauritius, the East African highlands, the Himalayas and south Asia. Two of these disjunctions are particularly relevant to a possible scenario for the origin of H. wyssii: Pinus canariensis may be most closely related to P rox- burghii of the western Himalaya, with fossil relatives in southwest Asia (AXELROD, 1986) ; the genus Appollonias (Lauraceae), one of the four lauraceous species found in the /aurisilva, has only two living species, A. barbajuna in the Canaries and A. arnotti in south India (SUNDING, 1979). Moreover, there are parallel examples among butterflies : the distribution of Vanessa indica (Herbst, 1794) (Nymphalidae), with distinct subspecies in Macaronesia (the Canaries and Madeira) and south Asia, has attracted recent attention (LEESTMANS, 1978 ; SHAPIRO, 1992a, 1992b) ; the genus Cyclyrius Butler, 1897 (Lycaenidae), which has only two living species, C. webbianus (Brullé, 1840) in the Canaries and C. mandersi (Druce, 1907) from Mauritius, presents a similar case (OWEN & SMITH, 1993). There is considerable evidence that many genera of butterflies from several families and subfamilies, including some satyrınes (PORTER & GEIGER, 1988 ; PORTER & SHAPIRO, 1991), are slow-evolving or brady- telic (Simpson, 1944). We believe that Hipparchia, in particular the ancestor of tewfiki-wyssii is probably a bradytelic taxon and that A. wyssii has a relatively ancient origin (LARSEN, 1984) in the Miocene, say 10 — 15 Ma. The first dispersal event, presumably from North Africa, was probably to the eastern islands of Gran Canaria and Fuerteventura, possibly at the same time as the invasion of the /auri- silva and P canariensis forest and before these islands became arid. The second dispersal event may have been from Gran Canaria to La Gomera. However, the low phenotypic diversity on La Gomera, compared to Gran Canaria, and indeed all other ıslands, suggests a bottleneck effect at introduction which is still reflected in the modern population. Subsequent island hops would follow, first to Tenerife, not earlier than 6 Ma (SCHMINKE, 1976) and then to El Hierro and La Palma during the Pleistocene (2 — 0 Ma). The increasing aridity of the Sahara region during the Pliocene would then produce the vicariance event which split the zewfiki-wyssii ancestor into two relict species. Comparative morphology and high phenotypic diversity, as well as the antiquity of Gran Canaria (SCHMINKE, 1976), support the proposed ancestral status of ssp. tamadabae. Whether ssp. wyssii on Tenerife originated from La Gomera or Gran Canaria (or both) remains an open 192 question, each being almost equally likely on grounds of comparative morphology (Table 6). The data indicate that ssp. bacchus (El Hierro) originated from La Gomera, the nearest source, at a date which must have been = 2 Ma ago. The case of ssp. tilosi, however, appears anomalous and defies simple interpretation. While it is undoubtedly closest to ssp. gomera (Table 6), it is the most distinct of all five subspecies (Fig. 3) and shares the smallest number of hindwing phenotypes with other subspecies ; ıt also shows the highest phenotypic diversity (Table 4). We suggest above that the fragmented distribution of ssp. tilosi into many small isolated populations, a situation which does not apply to the other subspecies, may have resulted in numerous founder effects with unusual and dif- fering starting sets of alleles ; sub-population differences might further intensify under subsequent genetic drift. Our collection is much too small to hope to find quantitative differences between the six sub- populations from La Palma represented, but the high phenotypic diversity in the bulked sample may reflect heterogeneity arising from the fragmented population structure of this subspecies. However, the fact that ssp. rilosi is the most distant (phenetically) from all other subspecies and occurs on the island known to be the youngest (= 2 Ma) (SCHMINKE, 1976) and furthest from a continental source of recruitment, suggest two other possible interpretations of the evolutionary history of H. wyssii. First, the species may have colonised the Canary archipelago only within the last two million years, in which case the diversification we describe occurred within the Pleistocene or later. If this is the case, then rapid evolution has occurred on El Hierro and (especially) La Palma. It follows from this that the pre-Pleistocene geological history of the islands would be irrelevant to any attempt to reconstruct the evolution of H. wyssii. Alternatively, the species may have reached the eastern islands a long time ago but dispersed to La Palma and El Hierro, where it has undergone rapid evolution, comparatively recently. This last interpretation best fits the facts. Discussion Graylings are essentially “underside” butterflies. Only rarely is the upperside visible and it is the underside that has the intricate and characteristic patterning. When a butterfly comes to rest, the underside of the forewing is well-exposed and its spots are conspicuous. After a short interval, the forewing is lowered and hidden by the hindwing, and the butterfly is beautifully camouflaged against the background 193 of rock or tree trunk. If alerted, it raises the forewing and the eyespots are again visible. This behaviour is widespread among members of the Satyrinae but is particularly well-developed in Hipparchia and it is usually interpreted as anti-predator strategy. The forewing eyespots catch the attention of a predator which may then strike at a non- vulnerable part of the wing (BRAKEFIELD, 1984), enabling the butterfly to escape by flying away. If there is no strike, the butterfly assumes the resting position with the forewing concealed. Our observations on all subspecies of A. wyssii suggest that this presumed anti-predator behaviour is the norm. The rarely exposed upperside is rather uniformly dark and may function in thermoregulation, though only in flight, as Hipparchia group species are exclusively lateral baskers at rest (SHREEVE & Dennis, 1992): it is probably never involved in anti-predator behaviour. Hence, we view the ground plan of the underside pattern of all five subspecies as having evolved in response to selection by predators ; most of this evolution must have occurred before what is now H. wyssii reached the Canary Islands. Assuming a mainland origin for A. wyssii, the initial colonisation of any one of the islands may have involved few individuals ; indeed a single fertilised female is all that is required. Subsequent colonisation of other islands might similarly involve few individuals. Each colonisation has produced relatively large but isolated populations which could easily have been founded with only a fraction of the genetic diversity of its source population(s) leading to selective and epigenetic constraint. The restricted gene pool of each founder population would thus be unique to each island and differ stochastically from all other islands : this alone could account for most of the inter- island differentiation we have described. Genetic drift in the initially small populations of founders would be expected to lead to a further loss of genetic diversity and to the fixation of inter-island differences, which are mainly so minor that their influence on survival may be trivial. NiyHoutT (1991) emphasises that small changes in the source or steep- ness of diffusion gradients for theoretical morphogens, thresholds for the expression of alternative pigment genes and pattern elements and the timing of the sequence of morphogenetic events, can produce quite profound changes to the visible phenotype. We believe that develop- mental constraint, probably involving very few gene loci with alter- native alleles, has produced the high proportion of unique character combinations that now occur on each island. The overall result is that the distinct grayling phenotype is retained but its precise expression 194 on each island is different and dependent on the genetic history of each population. The hindwing underside is the most complex of a grayling’s wing surfaces and it is this which is most often exposed to potential predators : it is a cryptic wing surface but the precise means by which crypsis is attained differs from island to island. Of the 30 species of butterfly found on the Canary Islands, four (in- cluding H. wyssii) exhibit inter-island differentiation in wing pattern morphology, while others probably do so but have not been subjected to detailed analysis. In all four cases, the island differences are quan- titative rather than qualitative. In two species, Maniola jurtina and Pararge xiphioides, subspecific names have not been given, while in the other two, Gonepteryx cleopatra (Linnaeus, 1767) and H. wyssii, subspecific (or specific) status is based on small differences in adult size, Wing pattern and the structure of genitalia (KUDRNA, 1975, 1977), and in the latter case, also on egg and larval morphology (WIEMERS, 1991). While these features differ slightly between islands, they vary only to an extent, as in comparisons between Palaearctic and Nearctic Aglais Dalman, 1816 and Nymphalis Kluk, 1802, that either species or subspecies might be expected to differ (MILLER & MILLER, 1990). To demonstrate speciation more positively would require cross-breeding or better, analysis of mtDNA. However, our view is that, although it hardly matters whether the island populations of H. wyssii are de- signated as species or subspecies, we have found no compelling evidence for full speciation and are thus persuaded to leave them as well- differentiated subspecies.

Yorkshire YO22 4UD, England Summary Danaus chrysippus Linnaeus, 1758, was first reliably noted from Algeria in 1912, from Morocco in 1943 and from Tunisia in 1952; it has since been recorded there sporadically. Sightings have increased in recent years and some have wrongly been claimed as new country records, due possibly to the erroneous claim in early editions (and English language editions/reprints up to 1993) of Higgins & Riley’s “Field guide to the butterflies of Britain and Europe” that the species had not been recorded from Algeria or Tunisia. Known records of Danaus chrysippus in the Maghreb countries of Morocco, Algeria and Tunisia are reviewed here. It is shown that the butterfly has established breeding populations in all three countries. Hostplants are discussed. Resume Danaus chrysippus Linnaeus, 1758, fut signalé pour la première fois d'Algérie en 1912, du Maroc en 1943 et de Tunisie en 1952 ; il a fait l’objet, depuis, de citations sporadiques. Les observations se sont multipliées ces dernières années, dont certaines indûment revendiquées comme nouvelles, censément en raison de l’assertion erronée des premières éditions (et éditions en langue anglaise, réimprimées jusqu’en 1993) du «Guide des Papillons de Grande-Bretagne et d'Europe» de Higgins & Riley, donnant l’espèce comme inconnue d'Algérie ou de Tunisie. Les citations de Danaus chrysippus des pays maghrébins du Maroc, d'Algérie et de Tunisie sont ici rassemblées. Il est démontré que le Petit Monarque a établi des colonies stables dans ces trois pays. Les plantes- hôtes sont étudiées. Zusammenfassung Danaus chrysippus Linnaeus, 1758, wurde aus Algerien erstmals 1912 gemeldet, aus Marokko 1943 und aus Tunesien 1952 ; seitdem wurde er dort sporadisch gesichtet. In den letzten Jahren häuften sich die Beobachtungen ; dabei wurden 201 einige fälschlich als Erstnachweise bezeichnet. Dies ist vermutlich darauf zurückzuführen, daß in früheren Ausgaben des Feldführers „Die Tagfalter Europas und Nordwestafrikas“ von Higgins und Riley irrtümlich behauptet wird, die Art sei aus Algerien oder Tunesien nicht bekannt. Die bisher bekann- ten Nachweise von Danaus chrysippus in den Maghreb-Ländern Marokko, Algerien und Tunesien werden zusammengestellt. Es wird gezeigt, daß der Falter in allen drei Ländern bodenständige Populationen besitzt. Die Futter- pflanzen werden diskutiert. Introduction There has been some confusion in recent years over the occurrence and distribution of the butterfly Danaus chrysippus Linnaeus, 1758, in the Maghreb states of Morocco, Algeria and Tunisia. Hiccins & RILEY, in all English language editions to date of their Field Guide to the Butterflies of Britain and Europe, currently the only guide to the region, stated that the butterfly is a rare migrant in Morocco and has not been reported from Algeria or Tunisia. The most recent French language edition is more up to date. A mass of further information has been published, in a number of languages in a variety of entomological journals, on the distribution of D. chrysippus in the Maghreb and in Europe with some recent papers claiming new records for Algeria and Tunisia. There has also been speculation and discussion on the probable hostplants of D. chry- sippus in North Africa. This paper sets out to collate published records to date ; to assess the present status of the butterfly in the Maghreb and to identify host- plants in each country. All localities can be found on the map (Fig. 1). Whilst the occurrence of D. chrysippus in Europe is outside the scope of this paper, it has been seen more frequently there in recent years and published records noted are included in the form of a bibliography. Records to date (M) = Morocco ; (A) = Algeria ; (T) = Tunisia 1905 — Joannis (1908 : 83), in his list of Saharan Lepidoptera recorded by Chudeau on a voyage from Algiers to Timbouctou in 1905-6, noted D. chrysippus ‘var.’ alcippus Cramer, 1777 taken at Oued Kadamellet on 21 September 1905 and as this has been quoted (including by the present author !) as the first published record of Danaus chrysippus in Algeria, it is worth taking a moment to establish where Kadamellet lies. It transpires that the locality is in Niger. 202 ¢ jesspJupwp| ® uejsob| DIDHEND uUyg e DAW peno® unowiwwiL e DIPP1DU9 4anoBBno] © vısınn x yonoybo7 e psy.” DAysig era eg e ““e $ auljuDjsUu0D e S#3191v "eIsıun], PUR BIIOS[Y ‘0990J0W UI "1 snddisduyo snoung Jo 39u211N990 UMOUY “| “LA N N N SUMO}[) >; suoljpjndod Buipee1qO SS sBuiyybis snddisksyo @ N Aa» DIUD/8/NDW (D1DyDS u1e/sem) POISSON e —. — —.

However, Mont Kadamellet was eventually identified on a very old map at 19° 34’ N, 8° 36’ E, some 45 km NNE of Iferouane, Air, the position loosely described by Joannis (1908 : 82). In June 1905, an agreement between the Commandant of what was then Haut Sénégal et Niger and the military commander of the Depart- ment de l’oasıs (part of Territories du Sud Algerien), determined a boundary between Algeria and French West Africa which was completed in principle by the Niamey Conventions of 1909 (International Boundary Study No. 99). Thus ’Kadamellet’ was and is in Niger, about 200 km SE of the Algerian border. 1907 — Seitz (1907 : 75-76), noted that [form] chrysippus was to be found on the Canary Islands “and the opposite districts of Morocco ... The absence of the insect from Algiers [Algeria] is very remarkable ... ab. alcippoides... in the Palearctic region only on the Canaries and in the opposite districts of Morocco ...”. The source of these comments is not clear ; there are no D. chrysippus from N Africa in the Seitz collection, now in the Senckenberg Museum, Frankfurt am Main (H. Schroeder, pers. comm.) 1912 — RoruscnuiL_p (1913: 114), recorded a male specimen from South Oued Mya (A) [30 April 1912] (another was seen but not captured) ; a female north of Ain Guettara (A) [8-11 April 1912] and a male from Igosten, Tidikelt (A) [15 April 1912] among the butterflies collected by Hartert in an expedition to the central western Sahara. He correctly noted these specimens as the first records for Algerian territory. The specimens remain extant in the Rothschild collection at the BM(NH). 1923 — Demaison (1923 : 134) reported his brother finding a single f. alcippus at Ghardaia (A) on 22 April 1923 and seeing several more on subsequent days in the same place. His brother also apparently found it commonly at Touggourt oasis (A) on 1 May 1923. In April 1927 Demaison’s brother returned to Ghardaia but saw no further specimens (Demaison, 1932 : 93), prompting Demaison to suggest that its occurrence in large numbers in the area in 1923 was due to an “accidental migration”. Apparently all individuals seen then were f. alcippus. He mentioned Gomphocarpus fruticosus (Asclepiadaceae), a known hostplant of D. chrysippus (ACKERY & VANE-WRIGHT, 1984 : 210), as a possible hostplant there. 1943 — Runcs (1945 : 15) noted 6 examples of f. “kanariensis” Fruh- storfer, 1898, [a doubtfully distinct race essentially of the “chrysippus” form (ACKERY & VANE-WRIGHT, 1984 : 115)], and one f. alcippus at 204 Messeied, Rio de Oro in SW Morocco (Western Sahara), taken on 20 January 1943 by Morales Agacino who observed further adults and larvae associated with Calotropis procera (Asclepiadaceae). 1947 — Runcs (1950 : 144-5) stated that despite much travelling in southern Morocco, he failed to find D. chrysippus until December 1947 when he found all stages of the insect abundantly some kilometres west of Taroudannt (M) ; of 38 specimens taken, only 6 were f. alcippus, the remainder being “f. kanariensis” |chrysippus] or alcippoides. The hostplant was Asclepias curassavica f. atropurpurea (Asclepiadaceae) ; RunGs expressed surprise at the apparent rarity of D. chrysippus in view of the availability of a number of different and presumably quite suitable Asclepiad hostplants. 1952 — CHnéoUR (1953) recorded Bede telling him that it was to be found frequently in the Biskra and Ghardaia areas of Algeria and that Kruglik had observed it in some numbers at Nefta (T). He recorded the capture, by Demoflys, of a single f. alcippoides at Gabés (T) on 4 July 1952. He added that since the time of this first observation, other specimens had been seen at Tozeur (T), Ain Draham (T) and Mégrine (T) (by Chpakowsky) and at Barrage de l’Oued Kebir (T) (by Massal and Arnould). This record was repeated (Chnèour, 1954 : 222) and the butterfly was depicted on the front cover of volume 7 of Bull. Soc. Sci. nat. Tunis. 1956 — Wyatt (1956: 220) recorded the species in the Sous valley (Taroudannt) (M) and noted that approximately 30% of individuals seen were f. alcippus. 1970 — Hıccıns & RILEY, in their Field Guide to the Butterflies of Britain and Europe, stated that D. chrysippus was a rare migrant in Morocco and not reported from Algeria or Tunisia ; claims reiterated in subsequent English language editions (1973, 1975, 1980, 1983) and reprints up to 1993. The French language edition of 1988, the only one the author has examined, went some way to correcting these mistakes. 1971 — Owen (1971 : 138 [Fig. 9.2]), included all of Tunisia and most of Algeria and Morocco well into the Sahara desert in the distribution of f. chrysippus in Africa. He showed f. alcippus occupying most of Morocco and part of western Algeria, far removed from the extensive populations of western Africa and went on to say (1971: 140) that maps were prepared after examination of the large collections in the British Museum [Natural History] and in the Hope Department of Entomology at Oxford. This is puzzling since the author was unable to find any D. chrysippus from N Africa other than from Egypt, Libya 205 and Mauretania and those recorded by Rothschild in 1912 in the BM(NH) collections, or in the Hope Department of Entomology at Oxford University Museum. A number of specimens from Morocco and Tunisia have been deposited by the present author in the BM(NH) collection. | 1971 — Kuprna (1972: 268) recorded the capture by Gawadi and Wilson on 1 September 1971 of 1 male and 3 females at Taroudannt (M) where it was common and fresh, having apparently bred locally. 1974 — PıERRE (1974) provided comprehensive discussion on the distribution of D. chrysippus throughout Africa and included parts of Algeria in the distribution of f. alcippus, as well as including W Moroccan and S Algerian records of f. chrysippus. This was based on a number of specimens in the collections of the Museum National d’Histoire Naturelle in Paris, namely Alger, Maison Carée (1, ex. Balachowski — alcippus) ; Touggourt (A) (5, ex. Babault — alcippus) ; Ghardaia (A) (l, ex. Demaison — alcippus) and Timmimoun (A) (1 chrysippus) (J. PIERRE, pers. comm.) 1975 — SAMRAOUI (1993 : 69) noted a specimen captured in Tebessa (A) in 1975, in the INVP collection in Algiers. 1979 — DEVARENNE (1981 : 171) recorded it in March and September/ October 1979 around Ghardaia (A) and figured an extreme male aberration taken in October of that year. 1979 — DE FRIENA (1981) recorded Menrad taking a series at Sousse (T) on 16 December 1979, some of which were f. alcippoides ; he also discussed several possible hostplants. 1979/80 — SCHUURMANS (1981) found D. chrysippus at Sousse (T) in 1979 and recorded Myncke finding it commonly from the begin- ning of August until mid-October at Monastir (T), Sousse (T) and Jendouba (T). 1980 — LEMPKE (1981 : 35) recorded a specimen at Sousse (T) on 2 March 1980. 1980 — van CAPPELLEN (1981) illustrated a female specimen found by Bolland on 11 March 1980 at Sousse (T). 1980 — LttrceEn (1981 : 55) found two examples of the nominate form at Tozeur (T) on 4 October 1980. 1980/1981 — There are specimens in the Museum National d’ Histoire Naturelle, Paris, from near Sbeitla (T) (7, Ex. Barbery & Aubertin, 1980/81 — chrysippus) ; R. Lheureux apparently also observed 3 spe- 206 cimens at Béthioua (A) and Mostaganem (A) in 1980 (J. PIERRE, pers. comm.) 1982 — BURTON (1982) mentioned several hundred D. chrysippus seen by Tombs in the region of Monastir (T) and Sousse (T) from 6 to 10 June 1982. 1983 — Cassar (1983) noted a total of 19 specimens on 10 and 13 July 1983 near Kairouan (T), La Kesra (T) and El Kef (T). 1985 — Between 12 and 24 June 1985, LEGLER (1986) saw a number of specimens in the area of Hammamet (T). 1985 — DEVARENNE (1990 : 154) reported it as common in various localities in Tunisia ; all stages of the butterfly were found in May 1985 between Sousse (T) and Port-el-Kataoui (T) feeding on Pergularia tomentosa (Asclepiadaceae). The butterfly was seen ın “almost every part of Tunisia, including Tunis”. 1985/6 — Cassar (1989) reported a single specimen seen by Balzan at Tunis (T) on 9 April 1985 and scores seen at Douz (T) in early October 1986. He went on to report a male specimen on 9 October 1986 at Touggourt (A) ; this last record was believed to be the first for Algeria. 1988 — Hünı (1988) saw the species near El Djem (T) and Sidi Bou Ali (T). 1988 — STEINIGER & EITSCHBERGER (1990 : 169), noted a specimen seen to the east of Tangier (M) on 25 October 1988. 1990 — Samraour & BENYAcouB (1991) observed a build up of D. chrysippus apparently migrating from east to west in the region of Annaba (A) and El-Kelaa (A) in May 1990; the last specimen seen in Annaba was on 17 October. On 27 August 1990 about 20 specimens were seen at Touggourt (A), also apparently moving in an cast/ west direction. 1990 — Observed to be widespread in small numbers beween Casa- blanca and Marrakech (M) on 3 October 1990; also seen near Tazenakht, 60km SW of Ouarzazate (M) on 11 October 1990 (Martin Jacoby, pers. comm.). 1991 — Samraout et al. (1992) noted the butterfly at Lac Bleu (A) (2) on 28 May 1991, El-Chatt (A) (1) on 14 June 1991, Lac des Oiseaux (A) (1) on 21 June 1991, Biskra (A) (numerous) on 19 July 1991, Laghouat (A) (numerous) on 26 July 1991, Ghardaia (A) (numerous) on 28 July 1991, Touggourt (A) (3) on 5 August 1991 and Taman- rasset (A) (1) on 10 October 1991. Calotropis procera (Asclepiadaceae) was suggested as a probable hostplant in central and southern Algeria. 207 1991 — 1 example was seen at the Gorges de Zeghzel, Berkane (M) on 28 September 1991 and about 15 specimens at the Moulouya delta (M) on 9 October 1991 by G. Chavanon (H.-J. Falkenhahn, pers. comm.). Author’s observations 1991-1993 MOROCCO: On 11 September 1991, a few individuals were seen in different localities on the eastern and northern outskirts of Taroudannt. The following day quite large numbers (40-60) were seen west of the town where there was a large stand of Asclepias curassavica growing in an irrigation ditch (TENNENT, 1993 : 27). On 3 March 1992 the area was revisited when it was found that the irrigation ditches had been cleared of all “debris”, including curassavica plants ; only a single D. chrysippus was seen to the east of Taroudannt. On 11 May, four specimens were seen in close proximity to curassavica plants at Ait Iazza, east of Taroudannt and on 4 June, a single example was seen flying across the main road 24 km east of the town. A further specimen was seen just south of Taroudannt on 2 September, the last visit of that year. In 1993, the locality west of Taroudannt where both the butterfly and hostplant were common in the autumn of 1991,was visited on 26 May. Although curissavica had begun to repopulate the ditch, individual plants were very small and no D. chrysippus were seen. However, at Ait lazza, both the plant and the butterfly were quite common ; with about 20 butterflies observed in a half hour period. Of D. chrysippus butterflies seen in Morocco, some 60-70% were of the nominotypical form, with the remainder being f. alcippus or alcippoides ; the latter were very variable, displaying a white hindwing patch of variable size or merely a few white scales around the inner margin. The author travelled extensively in Morocco in 1992 and 1993 but never saw D. chrysippus other than around Taroudannt and the Sous river valley. It was seen on each visit to the area, even when merely “passing through” ; individuals appeared generally to be freshly emerged. ALGERIA : From 15-17 March 1992, small numbers of D. chrysippus (about 10 in total) were seen close to the town of Ghardaia in central Algeria. Some individuals were possibly in transıt, but others appeared settled in an area west of the town where Pergularia tomentosa (Asclepiadaceae) grew commonly. A few Asclepias curassavica plants seen incorporated in a display along the central reservation of a street on the outskirts of Berriane, 40km north of Ghardaia, were thickly 208 covered in dust ; no D. chrysippus were seen. It was not seen at Toug- gourt some days later, although only a very cursory search was carried out. Two specimens were seen at Ghardaia on 3 October. In 1993, 2 individuals were seen flying aimlessly in the centre of Taman- rasset town on 24 April and a third (or one of the previous two again ?) in the same place the following day. A single example was seen flying across the road 34km south of Ghar- daia on | May. The very small entomological collection at the Institut National de la Protection desVegetaux in Ghardaia contains only three butterflies — 2 male D. chrysippus and 1 male Pieris rapae Linnaeus, 1758 (identified as P napi !) ; according to an official of the Institute, D. chrysippus is a regular visitor to the Institute gardens. Without exception, butterflies seen by the author ın Algeria have been of the nominotypical form. TUNISIA : On 4 October 1992, single specimens were seen at Degache and Tozeur ; the butterfly was very common in an oasis on the southern outskirts of Douz, about 150 individuals were seen in one afternoon including seven pairs in copula. Two larvae were noted on (?) Cynan- chum sp. (Asclepiadaceae). One freshly emerged male f. alcippus was seen ; the remainder of those seen at Douz and subsequently elsewhere in Tunisia, were f. chrysippus. On 5 October it was also common (in- cluding one pair seen in copula) in cultivated areas on the western outskirts of Gabes ; the following day two were seen flying in Gabes town centre and singletons seen at Oudre ; in the desert 42km west of Gabes ; El Guettar and Gafsa. On 7 October it was flying quite commonly in a dry river bed on the outskirts of Moulares and 3 days later, three were seen ca. 30km north of Sbeitla. In 1993, a year when the Spring season was delayed, one D. chrysippus was seen on the eastern outskirts of Gafsa and another near El Guettar on 30 March ; on 5 April a single specimen was seen at Douz. In October 1992, at the Institut National Agronomique de Tunisie (INAT) in Tunis, a display case containing preserved stages and host- plant (Pergularia tomentosa) of Danaus chrysippus was seen in the foyer of the zoology department, apparently prepared by Mon- sieur Hedi Smiri, an amateur lepidopterist working at the Institut National de la Recherche Agronomique de Tunisie (INRAT) in Sfax. On 23 March 1993 the author met Monsieur Smiri who confirmed that he had been breeding D. chrysippus regularly during the previous ten years from early stages found locally ; a search failed to find any 209 pupae, the only stage we might have expected to see since the butterfly had not yet emerged that year. Present Status Danaus chrysippus ıs a strongly migratory butterfly, with individuals often wandering far from established colonies. However, there is strong evidence that the species has established breeding colonies in Morocco, Algeria and Tunisia within the last 50 years. MOROCCO : Danaus chrysippus is clearly well established in the Sous valley, where it has almost certainly been resident since 1947 or earlier. It seems likely that the Morocco populations originated from western Africa ; forms alcippus and alcippoides form a significant percentage of the population. Although other Asclepiads are available, particulary in the south of the country, the only confirmed hostplant utilised by D. chrysippus in Morocco is Asclepias curassavica, introduced into Africa as a garden plant from Tropical America (Owen, 1971 : 34). The plant, which grows as a weed on the edges of fields and irrigation ditches around Tarou- dannt, seems to be irregularly but routinely destroyed by the local farmers and this probably has a direct bearing on the fluctuation of the D. chrysippus population. The botanist J. Gattefossé appears to have been the first to find curassavica in the Taroudannt area of Morocco in 1940 (Gattefossé, 1941 : 214). ALGERIA : It is interesting that the “invasion” of D. che to the Ghardaia and Touggourt areas recorded by Demaison in 1923 consisted exclusively of f. alcippus, whereas those seen in recent years have all been (where recorded) of the nominate form. Clearly, the butterfly has established for some years a breeding population at Ghardaia and Touggourt and probably elsewhere in that region. The hostplant(s) in Algeria is not clearly established. However, with the exception of Tamanrasset where the butterflies were seen only in the town centre, the asclepiad Pergularia tomentosa was present, usually commonly, in every locality where the author observed the butterfly. It seems likely therefore that this is the hostplant, though not necessarily the only one. Calotropis procera and other Calotropis species (Ascle- piadaceae) have been suggested as hostplants although, if that were so, one might reasonably expect D. chrysippus to be more common and widespread than it is in Algeria, since procera is a very common plant in the desert. It is a hostplant of D. chrysippus in West Africa (vAN DER HEYDEN, 1992). 210 TUNISIA : The butterfly is a notable vagrant and the relatively numerous records from various parts of Tunisia in the last 15 years may herald a spread in distribution from those areas of southern Tunisia (Sfax, Gabes, Douz etc.) where it appears to have been resident for some years. Although occasional individuals of f. alcippus occur, the resident form ıs apparently nominotypical like that to the west in east central Algeria. The primary hostplant in coastal Tunisia, including Sfax, Gabes etc., is Pergularia tomentosa, not recorded amongst the more than 50 Ascle- piadaceae hostplants for D. chrysippus listed by ACKERY & VANE- WRIGHT (1984 : 210-211). At Douz, the hostplant seems to be a (?) Cynanchum species ; the number of other possible asclepiad hostplants in Tunisia makes it quite likely that other species are also utilised.

Yorkshire YO22 4UD, England Summary Subsequent to the author’s previous work on the genus Berberia de Lesse in NW Africa (Tennent, 1994), in June 1994, a mixed population of B. abdelkader Pierret and B. lambessanus Staudinger was discovered flying in the Moroccan High Atlas mountains. A number of male butterflies were secured, all of which were clearly identifiable as either abdelkader or lambessanus. The probable hostplant was identified as Stipa parviflora. Résumé Après la publication de son article sur le genre Berberia de Lesse en Afrique du Nord occidentale (Tennent, 1994), l’auteur a découvert en juin 1994 une population mixte de B. abdelkader Pierret et B. lambessanus Staudinger qui volaient ensemble dans le Haut-Atlas marocain. Il a capturé une série de mâles dont tous étaient nettement identifiables comme abdelkader ou lambessanus. La plante nourricière des chenilles a été déterminée : Stipa parviflora. Zusammenfassung Nach der Publikation einer früheren Arbeit über Berberia de Lesse in Nord- westafrika (Tennent, 1994) wurde im Juni 1994 im marokkanischen Hohen Atlas eine gemischte Population von B. abdelkader Pierret und B. lambes- sanus Staudinger entdeckt. Alle gefangenen Männchen ließen sich eindeutig als abdelkader oder lambessanus bestimmen. Futterpflanze ist vermutlich Stipa parviflora. This short paper should be considered in conjunction with the author’s previous work on Berberia de Lesse (TENNENT, 1994). Since prepa- ring that paper in 1992, further lengthy visits have been made to the Maghreb, particularly Morocco, and on 8/9 June 1994, at 2150- JAY 2250 metres on the shores of Lac Tislit (Imilchil) in the Moroccan High Atlas mountains, a mixed population of Berberia abdelkader abdelkader Pierret and B. lambessanus Staudinger was discovered. In raising B. lambessanus to specific status, the author ventured the opinion (TENNENT, 1994 : 314) that B. abdelkader and B. lambessanus were unlikely to be found flying together because of (presumed) dif- fering biological requirements. The Tislit biotope consists primarily of extensive stands of Stipa parviflora grass (det. Mr. Roy Vickery, Dept. of Botany, BM(NH)), which presumably serves as the hostplant for both species. Neither species was particularly common. Most individuals were seen on a steep rocky slope where pursuit was difficult and in two days a total of 24 males and 1 female were secured ; collection was arbitrary, many more were seen than taken and it proved impossible to accurately determine identity in flight. The males comprised 20 (83%) typical abdelkader and 4 (17%) typical lambessanus ; the single female was tentatively placed as B. abdelkader. There are two possible explanations for the discovery of abdelkader and lambessanus flying together. Firstly, that abdelkader is a dimorphic (polymorphic if nelvai Seitz and taghzefti Wyatt are included) species or secondly, since by definition no two ’subspecies’ of the same form may fly together, that two separate species are involved. The first explanation may reasonably be discarded, since all other known popu- lations are almost exclusively of one “form” or the other and their respective hostplants are different (TENNENT, 1994 : 303, 314). Having said that, it is true that Jambessanus-like forms occur rarely in abdel- kader populations, and very infrequent specimens of lambessanus transitional to abdelkader were noted by the author in 1993 in the western Rif mountains and on Djebel Aourach, NE of the Dades gorge ; a circumstance not unexpected in such closely related taxa. Of the Lac Tislit material examined, most were fresh and all males were Clearly of one form or the other, with the upperside ground colour of lambessanus very dark brown, almost black and that of abdelkader dark chocolate-brown with the forewing apical ocellus ringed completely or partly by pale scales. Females of both species are generally difficult to separate. On balance, abdelkader from Tislit had a dark overall appearance compared with other populations, although many indivi- duals were indistinguishable from those taken by the author in several localities in Algeria. Apart from the obvious interest in finding abdelkader and lambes- sanus flying together, the occurrence of typical abdelkader in southern Morocco, some 380 km SW of the nearest previously known population, 218 is equally interesting and raises further questions as to the status of B. abdelkader nelvai and B. abdelkader taghzefti. One might have ex- pected abdelkader flying in the northern High Atlas to be 2. a. taghzefti, the nearest known population of which flies on the Tizi-n-Tairhemt in the extreme NE of that range (wrongly recorded by the author as being in the Middle Atlas mountains (TENNENT, 1994: 308, 309)), a little more than 100 km NE of Lac Tislit. In preparing the previous paper, the author believed that a case may be made for considering nelvai a good species, based on its distinctive appearance, unusually late flight period, apparently clear geographical parameters and the fact that typical abdelkader flies both to the west and (from the small number of specimens in the BM(NH) collection in London from the Gharyan hills in W Libya) to the east. Although the evidence was deemed inconclusive, finding typical abdelkader in S Morocco lends support to this view since nelvai and taghzefti are in effect surrounded both by typical abdelkader and lambessanus. Clearly, still more work needs to be done to finally resolve this inte- resting problem ; sadly the declaration by the FIS in September 1993 that foreigners in Algeria were considered a legitimate target, and the subsequent killing of many Europeans there, makes travel in that country in the foreseeable future impossible.

DARDENNE* & E. DROUET** * 9, allée Darwin, F-76230 Boisguillaume, France ** 9, boulevard Saint Simon, F-13009 Marseille, France Dans la nuit du 26 au 27 juin 1992, nous avons installé notre lampe à vapeur de mercure au pied d’une colline de sable (dune fossile ?) située à l'Ouest de Notre Dame de Gravenchon (Seine Maritime), le long de la route D 928 (UTM CQ28). Les pentes sont occupées par une garenne dont la végétation diffère notablement des biotopes des coteaux calcaires de la région et sont couronnées de taillis de Prunus, Crataegus et Salix. Notre observation s’est déroulée dans la deuxième partie de la nuit de 0h45 à 2h30 (heure légale). Quelques microlépidoptères se sont ajoutées aux 60 espèces de macrolépi- doptères observées et parmi eux Pempeliella ornatella (D. & S.) qui était demeurée inconnue de Seine Maritime. D’après le catalogue de L. LHOMME (1935-1949 : 21), la chenille de cette pyrale se nourrit aux dépens de Thymus serpyllum, plante répandue dans le lieu visité (Thymus drucei en Angleterre ; GOATER, 1986). Nous remercions le Dr. M. Laine pour la détermination de ce Phycitinae, qu’il avait signalé de l’Eure dans son catalogue (1986) d’après une capture de L. Dupont. Nous avons également pu capturer un exemplaire mâle très frais de Actinotia hyperici (D. & S.), Noctuidae nouvelle pour la Seine Maritime et connue depuis peu dans l’Eure (SAUVAGERE, 1989). La localité de Notre Dame de Gravenchon paraît être la plus septentrionale pour cette espèce dans le Nord Ouest de la France.

Summary Samples of Proclossiana eunomia (Esper, 1799) from Belgium and France were analysed by protein electrophoresis and morphometrics. The population from Morvan, central France, where the species was introduced from the Ardennes, is morphologically distinct from its mother population and has lost some alleles, due to a foundation effect. The within-region difference is usually small compared with between-region differences. The validity of the Pyrennean sub- species P eunomia ceretanensis Deslandes, 1930 is confirmed. Resume Des échantillons de Proclossiana eunomia (Esper, 1799) de France et de Bel- gique ont été analysés par morphométrie et électrophorèse des protéines. La population du Morvan, où l’espèce a été introduite depuis les Ardennes, est morphologiquement distincte et a perdu des allèles suite à un effet de fondation. Les différences au sein des régions sont en général plus faibles que celles entre les régions. La validité de la sous-espèce pyrénéenne P eunomia ceretanensis Deslandes, 1930 est confirmée. In Belgium, 81 of the 120 native species of Rhopalocera have shown a significant shrinking of their distribution this century (BAGUETTE et al., 1992). More than half of the Belgian butterfly species are threatened, being in the “endangered”, “vulnerable”, “rare” or “indetermined” IUCN classes of vulnera- bility (BAGUETTE & GoFFART, 1991). The species more prone to decline are those with strong ecological requirements, and often are linked with specific semi-natural habitats. To address concerns about the future of the declining 3 species, one needs information, not only of their distribution and habitat requirements, but also of their genetic diversity (FRANKEL & SouL£, 1980 ; ALLENDORF, 1983 ; TEMPLETON, 1991). In order to investigate how this distribution decline may affect the survival of the concerned species, genetic studies have begun independently in France and in Belgium in 1991 on Proclossiana eunomia Esper. This species has a very restricted habitat in western Europe : it is found in bogs and unfertilised wet meadows where its only local host plant Polygonum bistorta grows (HACKRAY & SARLET, 1969 ; DEscimon, 1976). The patchiness of this habitat may be seen at different scales, being due both to natural and human factors. Large formerly suitable areas have frequently been fragmented by spruce (Picea abies) plantations or by intensively managed and fertilised pasture lands. The local abundance of P eunomia and its strong habitat requirements make this species a good model to investigate how natural and man-made patchiness may influence the genetic structure of natural populations. How genetically distinct different populations are, and how organised this variation is, are the main themes of our research. The population genetics of P eunomia is currently being studied at different levels: local (within populations, within localities), regional (within regions), and between regions (within the European range of the species). Moreover, as new populations were founded in Morvan in 1970 and 1973, in an area where P eunomia was hitherto absent (DEscimon, 1976), the genetics of these populations are investigated and compared with the population of origin of the founder individuals. Methods P eunomia specimens were collected in 1991 in the French Pyrenees, in the two localites where it had been introduced in Morvan (central France), in various localities in Gaume (Southern Belgium) and in the Belgian and French Ardennes, including the locality of origin of the individuals which founded the Morvan populations (Fig. 1). A sample of 206 specimens collected in Morvan in 1977, and in the French Ardennes and the Pyrenees prior to 1991 by H. Descimon was added to the morphometric analysis. Specimens collected in the field were deep frozen in liquid nitrogen (-196°C) as soon as possible, and kept so until analysis. When thawed in the laboratory, the wings were kept for morphometric analysis, and the body was squashed in a pH 7.1 buffer (15% (w/v) sucrose, 50 mM Tris/HCl pH 7.1, 0.5% (v/v) Triton X-100, drop of Bromophenol Blue as runner marker; WYNNE & Brookes, 1992). Barascud followed the electrophoresis techniques described by PASTEUR et al. (1987), using horizontal starch gel electrophoresis, and Neve used cellulose acetate electrophoresis methods following RICHARDSON et al. (1986) and Wynne et al. (1992). Among various allozyme loci studied, the following proved to be polymorphic in the scored populations of P eunomia : Phosphogiucose isomerase (PGI, EC 5.3.1.9), amino aspartate transaminase 4 Fig. 1. Distribution of P eunomia samples. (AAT, EC 2.6.1.1), 6-phosphogluconate deshydrogenase (6PGD, EC 1.1.1.44) and phosphoglucomutase (PGM, EC 2.7.5.1). Morphometric studies of French specimens were carried out manually, using a binocular microscope and an internal ruler to measure linear dimensions of cells and spots on the wings (Fig. 2, Table 1). For Belgian specimens, an image analyser (description and use described in Winp1G, 1991) was used to take measurements of surface characters (Fig. 2, Table 1). In both cases a principal component analysis was performed on a first data set where 44 and 56 characters respectively were measured on a subsample ; then a set of as few correlated characters as possible was chosen to be measured on all specimens. On the whole, 152 French and 297 Belgian specimens were collected in 1991, of which only a portion has been analysed so far. Upperside Underside Fig. 2. Wing morphometric characters. Results The morphometric analysis shows that regions within France are well differen- tiated. The two populations founded in Morvan (central France) with females from the French Ardennes in the early 1970s, already show a significant diffe- 6 Table 1 List of brief descriptions of morphometric characters measured.

In order to maximise the distance between the regions, a canonical discriminant analysis was performed on the two data sets (Figs 3, 4). In France, on the first two canonical axes, a marked difference was found between the Pyrenean individuals and those from other regions. This result confirms the validity of the Pyrenean subspecies P eunomia ceretanensis Deslandes, 1930. The populations from Morvan were only slightly different from Ardennean popu- lations in 1977, but seem more so in 1991 (Fig. 3).

Allozyme analysis also confirms the validity of P e. ceretanensis, as populations from the Pyrenees show significant differences with that from the Ardennes (Table 2). In the introduced populations of Morvan, 6PGD has lost the polymorphism present in the mother population at Pont Collin, Ardennes, indicating that the Morvan populations have suffered from a bottleneck effect. Within Belgian populations, very low genetic differences have been observed so far, as the percentage of the commonest PGM locus varies from 72% to 81% in the 4 regions, and the difference is not significant. Too few data on other loci have been so far collected to allow any further discussion of this genetic data. Discussion The preliminary results of this ongoing study suggest that P eunomia popu- lations show high inter-region variation. This is not surprising, as it has been shown for other species with a disjunct distribution (e.g. Parnassius mnemosyne in South France, NAPOLITANO et al., 1988). However, local differentiation and genetic shift of introduced populations vs their mother population does not rule out the possibility of selection, which has been proven to occur on the PGM locus in Maniola jurtina (MASETTI & SCALI, 1976), but CARTER & WATT (1988) have shown that PGM heterozygosity of Colias philodice eriphyle varies with the date of sampling, which suggests a more complicated picture of adaptation of the different PGM alleles to temperature. The morphometric differentiation of the Morvan populations suggests selection pressure, pheno- typic plasticity, or both. Many questions may be raised at this stage in our study. In order to solve at least some of them we plan further work on P eunomia, which will involve (1) pooling both electrophoresis and morphometric data by using the same or compatible methods of investigation in both French and Belgian labor- atories ; (2) the collection of more specimens to allow detailed hierarchical analysis of both morphometric and biochemical characters ; (3) the study of further enzymes, in order to validate the estimation of genetic distances between populations and the use of Wright’s F statistics ; (4) various DNA markers will also be tested, to complement the electrophoresis results ; (5) 2 eunomia from other regions (e.g. Scandinavia, Bulgaria) will be studied, to investigate its global differentiation and its adaptations to various habitats ; it has been reported to feed on Polygonum bistorta in Belgium and France, on Viola palustris and possibly Polygonum viviparum in Scandinavia (HENRIK- SEN & KREUTZER, 1982) and on Vaccinium uliginosum and Andromeda poli- folia in Finland (MARTTILA et al. 1992). 10 Acknowledgements Special capture licences were given by the “Ministere de la Region Wallonne” (Belgium) and the “Ministère de l’Environnement” (France), as P eunomia is a protected species in both countries.

The most common vegetational types were downy oak (Quercus pubescens), holm oak (Q. ilex) and Kermes oak (©. coccifera) forests. The number and diversity of species increased between January and June, stabilising over the summer months, with a peak again in September, and dropped rapidly again from October. The larvae of species flying in winter and early spring generally feed on the leaves of trees, mainly beech, oak, pine and sallow. Such trees lose their importance as larval pabulum in moths flying later in the year; these tend to feed on annual plants. The best represented families were the Noctuidae and Geometridae. Résumé On a étudié la variation saisonnière des peuplements de macrohétérocères en Navarre (Nord de l’Espagne). Le nombre des espèces en vol et la diversité augmentent de janvier à juin, se stabilisent pendant l'été et subissent une forte baisse en octobre. Les espèces qui sont capturées en hiver et au début du printemps se nourrissent en général, à l’état larvaire, de feuilles d’arbre, sur- tout de fagacées, pinacées et de différentes salicacées. À mesure qu’avance le printemps, les arbres perdent de l’importance dans le régime alimentaire des chenilles, tandis que la consommation de plantes annuelles augmente. Les familles les plus riches en espèces sont les Noctuidae et Geometridae. Les formations végétales les plus fréquentes sont les rouvraies, les forêts de chêne vert (Quercus ilex) et les forêts de chêne kermes (Q. coccifera). Resumen Se estudia la variaciôn estacional de las poblaciones de falenas en Navarra (Norte de España). El numero de especies en vuelo y la diversidad va aumen- tando de enero a junio, se estabiliza en verano y en octubre sufre un brusco descenso. Las especies que vuelan en invierno y al comienzo de la primavera se alimentan en general, en estado larvario, de hojas de arboles, y a medida 13 que avanza la primavera los arboles pierden importancia en el régimen alimen- tario de las orugas, mientras que aumenta el consumo de plantas anuales. Las familias mas abundantes son Noctuidae y Geometridae. Las formaciones vegetales mas ricas son quejigares, encinares y coscojares. Introduction Une des principales caractéristiques des écosystèmes méditerranéens est la différence thermique et pluviométrique importante qui existe entre les saisons, et même d’une année à l’autre. Cette «saisonnalité» marquée, ajoutée aux fluctuations interannuelles (en particulier en ce qui concerne la pluviométrie), donne lieu à une végétation très caractéristique, dont l’une des principales adaptations est la résistance à de longues périodes de sécheresse (Copy & Mooney, 1978). Cependant, les adaptations morphologiques et physiologiques ne sont pas les seules stratégies que les plantes ont opposé aux irrégularités climatiques ; elles ont également développé des stratégies phénologiques grâce auxquelles les phénoménes vitaux fondamentaux (floraison, fructification, etc.) se sont ajustés avec précision aux conditions météorologiques. Bien évidem- ment, les plantes ne sont pas les seuls organismes qui subissent des fluctuations climatiques ; cependant, leur immobilité leur interdit les stratégies évasives comme les migrations, les diapauses, les comportements nocturnes, etc, que les animaux, et en particulier les insectes, peuvent mettre en pratique. L’ajustement des cycles biologiques des insectes aux saisons est particuliere- ment marqué dans le cas des phytophages, qui doivent s’alimenter dans une période au cours de laquelle les plantes sont plus sensibles, à cause d’un faible taux en tanin ou bien de la présence d’organes adéquats pour l’almentation des phytophages (feuilles, fleurs, fruits, etc.). Dans ce travail, nous analyserons les fluctuations de différentes variables écologiques des populations de macro- hétérocères dans la province de Navarre (Nord de l’Espagne), tout au long de l’année, et en relation avec le type de végétation et l’utilisation du territoire. Concrètement, nous nous sommes interessés au nombre d’individus et d’es- pèces capturés chaque mois, a la diversité et à l’équitabilité, de même qu’à la variation de la composition des taxocénoses de ces lépidoptères. Ce type d’étude dans la Péninsule Ibèrique n’a été antérieurement réalisé que par SARTO 1 MonTEYs (1984) dans le Massif du Montseny (Barcelone) et par YELA (1990) à Trillo (La Alcarria, Guadalajara). Matériel et méthode 38 160 exemplaires de Lépidoptères adultes ont été capturés au moyen de pièges lumineux, pendant 15 ans, dans l’ensemble de la province de Navarre. Les pièges étaient fixes, situés dans des centres agronomiques ou des fermes et ils fonctionnaient automatiquement de la tombée de la nuit jusqu’à l’aube. Au total, pour ce travail, les échantillons récoltés provenaient de 19 points 14 Tableau | Localites UTM = Coordonnées selon un quadrillage de 10 km de côté. Alt = Altitude en mètres.

La province de Navarre est située au nord de la Péninsule Ibérique, sa super- ficie est de 1 042 100 ha (10 421 km?) et elle présente de forts gradients de direction nord-sud. Dans la partie septentrionale, le climat est nettement atlan- tique, avec des hivers doux et des étés frais et humides (Tableau 2) alors que dans la région centre et le sud de la province, les hivers sont froids et les étés chauds et secs. Le régime climatique induit une végétation très variée, comparable à celle de la région eurosibérienne dans le nord et à celle de la région méditerranéenne dans le sud. Ce gradient est accentué par la présence des Pyrénées à l'extrémité septentrionale et la vallée de l’Ébre dans la frange méridionale (Tableau 1). Résultats Au total, ont été capturés 38 160 exemplaires de papillons appartenant à 14 familles et 651 espèces, présentés en détail au Tableau 3. On peut voir que la plupart des espèces appartiennent aux familles Noctuidae et Geometridae (81,9%) alors que la plupart des individus appartiennent aux familles Noctuidae et Arctiidae (respectivement 74 et 62%). 15 Tableau 2 Données climatiques L = Latitude en degrés.

Dix-neuf localités pré- sentaient un échantillon à peu près homogène et ont donc été conservées. Groupées par mois, les 20 espèces les plus abondantes sont présentées aux Tableaux 4.1 à 4.12. On peut noter qu’en janvier et février (Tableaux 4.1 et 4.2) il y a peu d’espèces et d’individus en vol, bien qu’une légère augmentation apparaisse. Les espèces les plus abondantes sont les mêmes pour ces deux mois, une noctuelle et une géomètre.

Dans le cas de Agrochola lychnidis et Colotois pennaria, il s’agit d’especes qui hibernent sous forme d’œuf ; janvier et février correspondent alors a la fin de leur période de vol. Notons de plus, que les localités où ont été capturés les individus de ces espèces se trouvent toutes dans le sud de la province: Larraga (9), La Oliva (13) et Marcilla (18), là où la végétation potentielle se compose de Quercus ilex (chêne vert, les deux premières) et Quercus coccifera (chêne Kermès, la dernière). 2 a u : 1 © À) © -J D ı 1 N° exemplaires : 39 15 N° espèces : 16 9 En mars, on note une augmentation sensible du nombre d’exemplaires et d’espèces (Tableau 4.3). On trouve en particulier Conistra alicia et Chemerina caliginearia, mais également quelques Orthosia sont déjà plus abondantes (O. incerta et O. gothica). L'alimentation larvaire des imagos capturés en mars se réalise surtout au dépend des arbres (Quercus, Fagus, Salix, Populus, Ulmus, Tilia, Betula, etc.) ou arbustes (Crataegus, Malus, Prunus, Genista, etc.). Les espèces les plus abondantes sont en général celles qui passent l’hiver au stade chrysalide. En avril, le nombre d’individus et d’especes en vol continue à augmenter (Tableau 4.4). Onze des seize espèces de mars se capturent encore, auxquelles s'ajoutent six nouvelles. Bien que deux Arctiides soient en tête de la liste d’abondance (Diaphora mendica et Phragmatobia fuliginosa), les plus abon- dants sont les Noctuides ; les Géométrides sont encore rares. Les zones comp- tant le plus d’individus et d’espèces capturés sont la région moyenne et la Ribera (centre et sud de la Navarre), bien qu’apparaissent déjà des individus dans la région nord. L’alimentation larvaire des imagos capturés en avril, se réalise principalement sur des plantes basses annuelles, tant sylvestres que cultivées, bien que les premières soient les plus importantes. L’abondance de celles qui s’alimentent sur les arbres ou arbustes à feuilles caduques (fagacées et salicacées) diminue. Les espèces les plus abondantes ont hiberné au stade chenille, probablement non complètement développées. 28 En mai, la tendance à l’augmentation s’accentue (Tableau 4.5). Les localités de la vallée de l’Ebre et de la zone moyenne sont toujours les plus riches. En effet, en mai, des gelées peuvent toujours se produire dans la région nord, et les températures moyennes nocturnes sont encore basses en montagne. Les espèces les plus abondantes sont les Noctuides (Mythimna vitellina) et les Arctiides (Diaphora mendica et Phragmatobia fuliginosa), bien qu’apparaissent déjà des Sphyngides, Géométrides et Cossides. L’alimentation larvaire des especes les plus abondantes repose surtout sur les plantes basses de la famille des Astéracées et des Poacées. En juin, on peut noter une grande augmentation du nombre d’individus et d’espèces en vol, même dans le nord de la province (Tableau 4.6). Parmi les 10 espèces les plus abondantes, on trouve trois Arctüdes (P. fuliginosa, Eilema caniola et Spilosoma lubricipeda) et quatre Noctuides, bien que la densité de celles-ci commence à diminuer à partir de ce mois. L’alimentation larvaire des espèces les plus abondantes se réalise sur les Astéracées et dans une moindre mesure les Poacées et Fabacées. En juillet, les captures du nord de la province prennent de l’importance tandis | que celles du sud commencent à se raréfier (Tableau 4.7). De nouveau, l’espèce la plus abondante est l’Arctiide (P. fuliginosa). Les Noctuides les plus abon- dantes sont Emmelia trabealis, Tyta luctuosa et Acontia lucida. Les espèces Malacosoma castrensis, Lymantria dispar et Thaumetopoea pityocampa sont également représentées. Les larves des espèces les plus abondantes s’alimentent de la strate herbacée (Astéracées, Poacées, Polygonacées, Plantaginacées, etc.) et quelques-unes également exploitent la strate arborée (Fagacées et Pinacées), en particulier dans la région nord de la province. En août, les captures sont toujours très abondantes, bien que les localités du sud y contribuent de moins en moins (Tableau 4.8). En général, les Arctiides sont toujours les plus abondants ; les Noctuides les plus communes sont, comme le mois précédent Emmelia trabealis, Tyta luctuosa et Acontia lucida. Les espèces les plus abondantes continuent à exploiter en priorité la strate herbacée ainsi que les lichens, ceci étant dû sans doute à la présence des deux espèces d’Eilema. En septembre, les captures sont toujours abondantes au nord de la province et elles reprennent de l’importance dans le sud (Tableau 4.9). Les Arctiides déjà citées sont toujours en tête de la liste de captures. Viennent s’y ajouter les Lasiocampides (Lasiocampa trifolii) ou Géométrides (Abraxas pantaria) et surtout les noctuides (Emmelia trabealis, Hoplodrina ambigua, Xestia xanthographa, Tyta luctuosa, Mythimna vitellina et Noctua pronuba). Les plantes nourricieres des larves sont encore les Astéracées, Poacées et Poly- gonacées et les Rosacées prennent de l’importance. En octobre, on note une forte baisse, tant du nombre d’individus captures que du nombre d’especes (Tableau 4.10). Parmi les dix espèces les plus abon- dantes, neuf sont des Noctuides et la dixième une Arctiide. Les localités qui comptent le plus grand nombre d’individus capturés sont situées dans la région 29 moyenne et la Ribera. L’alimentation des larves se fait aux dépens des plantes herbacées annuelles comme les Poacées, Astéracées, Fabacées et Polygonacées. En parallèle, commencent à apparaître des adultes dont les larves se nourrissent de Rosacées et de Salicacées. En novembre, la baisse du nombre d’individus et d’espèces capturés, en parti- culier dans le nord de la province, s’accentue (Tableau 4.11). Les espèces les plus communes appartiennent à la famille des Noctuides (Agrochola lychnidis, Mythimna unipuncta, etc.). L'alimentation larvaire des espèces les plus abon- dantes se réalise sur les Rosacées, Poacées, Salicacées et Fabacées, avec une exploitation encore plus importante des plantes basses annuelles que des arbres ou arbustes. Les espèces capturées en novembre hibernent en général au stade œuf bien que quelques-unes le fassent au stade chenille. En décembre, on note une forte diminution des captures (Tableau 4.12). Parmi les dix espèces les plus abondantes, il y a neuf Noctuides et une Géométride. Les plantes exploitées par les larves sont les mêmes qu’au cours du mois précédent. Les espèces capturées en décembre hibernent à différents stades, mais on note que les espèces qui hibernent au stade imago prennent de l’im- portance. En résumé, et si l’on considère les dix espèces les plus abondantes, chaque mois (numerotées de 1 a 10) en fonction du nombre d’individus capturés (Tableau 5), on peut noter que peu d’espèces sont représentées dans ce tableau car pour la plupart, elles sont présentes pendant plusieurs mois. On trouve deux Cossidae, trois Lasiocampidae, deux Sphingidae, huit Geo- metridae (deux Larentiinae et six Boarmiinae), une Thaumetopoeidae, deux Notodontidae, une Lymantriidae, sept Arctiidae et quarante Noctuidae (une Catocalinae, deux Acontiinae, six Amphipyrinae, treize Cuculliinae, dix Hade- ninae et huit Noctuinae). Les Arctiides predominent sur le reste, grâce sur- tout à l’abondance de Phragmatobia fuliginosa au printemps et en été. Les Noctuides dominent en automne et en hiver, bien qu’elles soient abondantes toute l’année. Discussion Les espèces qui sont capturées en hiver et au début du printemps (de décembre à mars) se nourrissent en général, à l’état larvaire, de feuilles d’arbre, surtout de Fagacées (Quercus, Castanea, etc.), Pinacées (Pinus) et de différentes Sali- cacées. À mesure qu’avance le printemps, les arbres perdent de l’importance dans le régime alimentaire des chenilles, tandis que la consommation de plantes annuelles augmente (Astéracées et Poacées principalement). Si l’on observe les cycles biologiques de ces espèces hibernantes, il apparaît que la phase chenille est atteinte au printemps et que ces animaux passent la période été-hiver au stade chrysalide ou parfois imago. 30 Dans tous les cas, les chenilles utilisent les feuilles des arbres au moment le plus approprié pour l’alimentation. En effet, il a été démontré que le contenu en tanin des feuilles augmente et qu’elles perdent de l’eau à mesure qu’avance le printemps (SCRIBER & SLANSKY, 1981) et en réponse aux premières attaques des herbivores, de sorte que leur qualité nutritive diminue. Une telle relation a été décrite pour le chêne et Operophtera brumata L. (Geometridae) (FEENY, 1970), et Lymantria dispar L. (Lymantriidae) (ScHULTz & BALDwin, 1982), et enfin pour différents lépidoptères mineurs (FAETH ef al., 1981 ; FAETH, 1986 ; 1988). Ce renforcement des défenses chimiques des arbres peut même être induit à distance comme le suggèrent BALDWIN & SCHULTZ (1983) pour les peupliers et les érables. L'utilisation par les chenilles des feuilles des arbres au printemps n’est pas une exclusivité, parmi les lépidoptères, des hétérocères ; en effet, il est bien connu que les Lycénides, qui hibernent au stade œuf, se nourrissent de feuilles d’arbres au cours des premiers mois du printemps (MARTIN CANO, 1982). Les plantes ont développé divers mécanismes pour prévenir les attaques des phytophages et ceux-ci, de leur côté, ont essayé d’esquiver ou éviter ces méca- nismes (RHOADES, 1985). Le résultat de cette interaction est en definitive un ajustement chaque fois plus fin entre l’hôte et l’herbivore. Cet ajustement se manifeste non seulement au niveau physiologique (présence de tanins, toxines, etc.), mais aussi au niveau de la synchronisation des cycles vitaux de la plante et de l’insecte phytophage (STRONG et al., 1984 ; TEMPLADO, 1990). Ce dernier aspect est une fois encore mis en évidence par nos résultats. Les espèces qui volent des le mois d’avril se trouvent à l’état larvaire de mai à novembre avec estivation et hibernation à différents stades. Leur alimentation larvaire est principalement constituée de plantes herbacées annuelles, chez lesquelles la défense chimique contre les herbivores ne se base pas tant sur la présence de tanins que sur la présence de toxines. Diversité La diversité définit de façon simple et synthétique, bien qu’incomplete, la structure d’une communauté. De ce fait, cette variable est fréquemment utilisée pour comparer différents échantillons, qu’ils proviennent de la même localité (variation annuelle) ou de différentes régions (variation spatiale). Les indices de diversité sont divers et variés (voir MARGALEFFE, 1977 et MAGUR- RAN, 1988) ; en général, ils prétendent établir la richesse en espèces d’une communauté, en relation avec une unité d’Echantillonnage. Du fait de sa facilité de calcul et son utilisation répandue (ce qui permet de comparer les résultats de divers travaux), nous avons employé l’indice de Shannon (SHANNON- WEAVER, 1957). 31 cl I] DAIDISA] "7 DINAJOAYIO 7 DAWUOWDUUI) J Opn “Ve SIDAqvA] ‘A DSONJON] ;] DIIpUaU ‘(J ppadinaqny 'S Doipnd ‘> psoursynf{ “Yd pjoapusad 7 DJOIUDO “7 puvjduoo 7 dpdsip "J DINWAA] “Yd D9149Q1 ‘7 pdwosodnd ‘YJ, DIADAAYIO ‘YF DIADOU151]D9 “YD DIADIDAIS ‘4 DIADUUId ‘7 DIADULANUL |] DIADJUDd ‘vy DIDfnA “YD DIADAD]I "7 sn]j22404 ‘(7 yndod 7 of 7 SISUIAISDI ‘IN SON DINAN WNAJSIDI J : SON soyuepuoge snyd sa s999dsa sap srow ed uonefoy ¢ negqey, oe PINJOON LN Jepı.muewAT] 9PPIJUOPOION seproodojourney |, HEPLIWWIOAN) oepisuryds ov pidureooise’] IVPISsOD 32 DSOIUQNU I DYADABOYIUDX "X WUNABIU- 2 °X DIONDS 4 DSO910]3 J pqnuoid 'N piaajd ‘CO uonsdi ‘F DINOIS “A pjoundiun ‘py DUTCH WV pjsundigjp "MW DI1YIO8 ‘OC DIAJIUI ‘OC 1SD122 ‘O SI19D18 'O SLAD]PIDIASUOD “FJ D29D19]0 "7 SLID]JAIO X psoun] 'O sıpıuyad] 'Y SSL DE Vy D 17 DP14101 ‘7 EUROS) HD) papol ;] popıdsol 1 D]024D 'X DJ9]0SX2 “XY DASIU “YY DXI TS DNBIGUID 'H DSOIN] “YM se PINJSON 33 : D; D; =>; nm + 102 =| H = Indice de Shannon. n; = Nombre d’individus de l’espèce i. n = Nombre total d’individus captures. s = Nombre total d’especes capturées. L’analyse de la diversité annuelle dans les différentes localités de capture (Tableau 6) révèle des valeurs très élevées, ce qui indique que les communau- tés de lépidoptères que l’on y observe sont relativement stables malgré une importante disproportion dans les taux d’abondance. En effet, la plupart des espèces capturées sont rares ou très rares et seule une infime minorité peut être considérée comme abondante (Tableau 7). Vingt-cinq des trente échantillons considérés et appartenant aux 19 localités étudiées, présentent un indice supérieur à quatre. Tout au long de l’année, la diversité fluctue de différente façon, selon la localité considérée (Tableau 6). En général, la diversité augmente de janvier à juin ou juillet, se stabilise ou diminue légèrement en été, recommence à augmenter au début de l’automne et diminue brusquement en novembre. Si l’on réorganise les données du tableau 6 de sorte que n’apparaissent que les trois mois pour lesquels l’indice de Shannon est le plus élevé, on obtient le tableau 8 dans lequel ne figurent plus que dix-neuf échantillons (provenant de quinze localités). Par exemple, dans la première ligne du tableau, le numéro huit indique que pour la localité de Lecäroz et pour l’échantillonnage de 1983, le mois d’août présente l’indice de Shannon le plus élevé, suivi par les mois de juin et mai. On note qu’en octobre la diversité est maximale dans la plupart des localités (sept sur dix-neuf) ; viennent ensuite les mois de juin et juillet, puis mai, août et septembre. Aucun des autres mois ne présente jamais de valeur maximale pour l’indice de Shannon. Pour les localités du nord de Navarre, la diversité maximale est atteinte en été et au début de l’automne alors que dans de nombreuses localités du sud (Ribera), les valeurs les plus élevées sont obtenues à la fin du printemps, bien qu’elles restent élevées jusqu’en automne (octobre). Si l’on met en relation ces données avec l’incorporation à l’ensemble, de la nombreuse communauté des Noctuides, en particulier Hadeninae, avec vol printanier, et Cuculliinae et Noctuinae, dont le vol est automnal, on peut dire que les valeurs maximales de l’indice de Shannon, à la fin du printemps se justifient par l’apparition essentiellement de la première génération (et parfois la seule) des Hadeninae. Le maximun automnal doit être lie à l'émergence des Cuculliinae et des Noctuinae, avec lesquelles coïncident en plus les espèces qui ont subi une diapause estivale. Le maintien d’une diversité élevée pendant l'été et au début de l’automne dans la région nord doit être lié tant à la longueur et a la rudesse de l’hiver qu’à la relative douceur de l'été, alors 34 que dans la région de la Ribera, caractérisée par un été chaud et sec, la diversité chutera des juillet. Les douze Echantillons de plus grande diversite sont, dans l’ordre : Ilundain 1984 (Rouvraie) 615 Marcilla 1985 (Forêt de chêne Kermes) 606 Larraga 1985 (Forêt de chêne vert) 591 Mendavia 1984 (Forét de chéne Kermes) 5°83 Sartaguda 1985 (Forét de chéne Kermes) 581 Lecaroz 1983 (Chénaie) 5776 Ilundain 1983 (Rouvraie) 5770 Ucar 1986 (Rouvraie) 5°63 Bunuel 1984 (Forét de chéne Kermes) 5°62 La Oliva 1985 (Forét de chéne vert) 5°58 Fontellas 1985 (Forét de chéne Kermes) Sal Ucar 1987 (Rouvraie) 541 Comme l’indique la liste ci-dessus, rouvraie, forêt de chêne Kermes et forêt de chêne vert, sont les formations végetales présentant la plus grande diversité. L’echantillon annuel le plus riche a été observé à Ilundäin en 1984, dans le domaine du Quercus faginea et présentait une diversité réellement élevée (615 bits/individus), avec 290 espèces. Ce résultat concorde avec ceux obtenus pour Papilionoidea et Hesperioidea dans le centre de la Péninsule Ibérique (VIEJo, 1985 ; VıEIO et al., 1989), qui révélaient une importante diversité dans les forêts de chêne vert. Cependant, si l’on calcule la diversité globale des forma- tions végétales, les forêts de chêne vert sont les plus riches, mais suivies de près par les rouvraies et les forêts de chêne Kermès ; quoi qu’il en soit les rouvraies sont celles qui présentent le plus grand nombre d’espèces (378). Chênaie 576 (85 esp.) Hétraie 4773 (66 esp.) Rouvraie 6731 (378 esp.) Forét de chéne vert 6’54 (355 esp.) Forét de chéne Kermes 629 (331 esp.) L’analyse de l’équitabilité dans les différentes localités (Tableau 6) indique une diminution au cours de l'été, que l’on attribue a la diminution de la diversité par rapport au maximum possible, en tenant compte du nombre d’espèces obtenues. Conclusions La Navarre est une région riche en macrohétérocères ; nous y avons capturé 651 espèces de 14 familles, ce qui représente 44,9% des espèces iberiques. Les localités les plus riches se situent dans le domaine climatique des chênaies (Quercus), en particulier les chênes verts, chênes rouvres et chênes Kermès. Bien que la plupart des localités soient situées en zones agricoles, cette activité ne semble pas altérer de façon importante la structure des communautés de macrohétérocères si l’on s’en tient aux valeurs de l’équitabilité, supérieures en général à 0,75, ce qui signifie que la diversité réelle est proche du maximum. 35 jonuuy nv a N O 4 S (G-+-N+0) suwoiny : ny (S+V+L) 94:4 (HN+V) Sduauuq : 14 (N+4+f) ATH : H : SUOSTES AQUUE,] 2P SUC] ne INO} uorerIeA AnaJ‘9710907 anbeuyo op aiqenbs 19 uouurys ap sdIpu] 9 nesfgeL S999dS9,P oN SUIPIAIPULP oN npgennbg uouueyS L86E EI} S999dS9,p oN SnpPIAIPULP oN rnmgeymbg uouueys 986T 189N S999dS9,p oN SNPIATPULP oN npgennbg UOUUBUS p861I ulepungj S999dS9 p oN SRPIATDUT PAC N] pgennbg uouueyS C86, uIepungj S999d$S9 p oN snpIAIPULP oN npgennbg uouueys 9861 zou sa99dsa,p oN snpIAIpuULP oN mgermbg uouueys C86 ZOAEI9] S999dS9 p „N SnPIATPULP oN ngeymbg uouueys 9861 VSULICT sooodsa.p „N SNPIATPULP oN suiqeynby uouueys CS6I edeue] sa99dsa,p „N snpIATPULP oN ngennbg uouueys 9861 &Z1930 S999dS9 p „N snp EN Por oN nmgeynbg uouueys 986] EUOIZV sooodsa.p „N SNPIAIPULP oN npgennbg uouueys L861 BIEZLIV sa9adsa,p „N SNPIAIPULP oN nmgennbg uouueys 9861 EIEZLIV so99dsa,p oN snpIATPULP oN npgeynb uouueys S861 PANO UT so00dsa,Pp oN SNPIATPULP oN npgennbg uouueyS L861 ONNSEI1E) S999dS9,P oN SOP ETD UT DuoN gennbg uouueyS 9861 OIIHSEIIE) 299d$9 p oN SUDIAIDURD oN npgennbg uouueyS 9861 pase) S999dS9,p oN snpIATPULP oN npgennbg uouueyS S861 EPISE) S999dS9,P „N snpIATPULP oN nngennbg uouueys E86T esandues pnuuy nV sooodsa.p „N SNPIAIPULP oN nngeynbg uouueys S861 EIIDIEN sooodsa,.p „N SIPIATPUrP ON annaba uouueys 7861 UBLIPV UBS S999dS9,p „N SUIDIATPULP oN nngernbg uouueys S86 pneus sooodsa.p „N SDpIAIDULP oN anrqermbA uouueys P86l epndenes sooodsa.p „N snpIAIPULP oN aurqeynbA uouueyS ÿ86I elAeEpuUSN sooodsa.p oN snpIAIPULP oN ngeymbg uouueyS 9861 PANO ET S299d$9,p „N SnpIAIPULP oN ngennbg uouueyS y86I Pnung S999dS9 p oN SNPIATPULP oN anrqembA uouueys S861 SEIJUO sooodsa,.p oN SNPIAIPULP oN nmgennbg uouueys S86I ByoIpe) sooodsa.p oN snpIATPULP oN ngennbg uouueys P86 BWoIpe+) S292dS9,p oN SNPIAIPULP oN nmgeymbg uouueys C86 BWoIpe+) S999dS9,p oN snPIATPULP oN auraqernbA uouueys 9861 EIIDAEN Tableau 7 Degré d’abondance des espèces capturées Degré Nombre Pourcentage Nombre Pourcentage d’abondance d’espèces n° d’espèces d'individus n° d'individus >2000 1001-2000 501-1000 251-500 51-250 26-50 <26 Tableau 8 Réarrangement des différents mois en fonction de leur importance pour l’indice de Shannon Divisions géographiques de la Navarre : Dt : Division traditionnelle (M = Montagne.

Supplement No. 5 : 45-49 ; 31.X.1994 ISSN 0342-7536 Biogeographical and ecological determinants of the central European peat bog Lepidoptera : The habitat island approach to conservation Karel SPITZER Institute of Entomology, Czech Academy of Sciences, BraniSovska 31, CZ-370 05 Ceské Budéjovice, Czech Republic Summary Oligotrophic peat bogs form characteristic habitat islands within the temperate forests of central Europe. These isolated relict bog ecosystems are similar to some subarctic and subalpine biomes (“edaphic forest-tundra”) in being deter- mined in the Holocene and by recent local ecology. The ecological determinants are interactions of suitable edaphic and climatic factors. Most of the tyrpho- biontic and tyrphophilous Lepidoptera species have taxonomic affinities to boreal and subarctic zones. The “archipelago” of South Bohemian oligotrophic bogs is ideal for case studies, and model conservation projects. Bog habitat island : outline of ecological history Central European oligotrophic peat bogs (e.g. Mrtvy luh bog, Fig. 1) are isolated ecosystems similar in structure and function to subarctic wet forest- tundra (= “edaphic forest-tundra” sensu Husticu, 1957, see also TUHKANEN, 1984). In southern latitudes of the temperate forest zone, such peat bogs are characteristic azonal ecosystems, occurring in isolated and discrete patches in “average” landscape originally covered by forest. The habitat island develop- ment of most central European bogs, e.g. in South Bohemia, dates from the early Holocene (JANKovsKA, 1980) and the bogs became more acid and ombrotrophic during the Holocene ecological succession. The island-like characteristics have resulted from the interaction of both climatic and edaphic factors. Recently, the local cold/warm and wet/dry “continental” environment has been the main factor favouring the survival of relict cold adapted (stress tolerant and K-selected) biotas. Because of their different ecological histories each large bog is unique in its species composition (e.g. insects) and their taxonomic status (subspecies and geographical races). These central European oligotrophic bogs can be classified under the vegetation association : Pino rotundatae-Sphagnetum (see NEUHAUSL, 1972 ; SPITZER, 1975 ; MIKKOLA & SPITZER, 1982, etc.). The linkage between insect community and vegetation 45 Fig. 1. The habitat island of Mrtvy luh bog, ca. 300 ha of edaphic “forest-tundra”, Sumava Mts., 740 m. association is very close, e.g. Lepidoptera associated with Ledum palustre (Lyonetia ledi Stt., Olethreutes lediana L., Eupithecia gelidata Möschl.) and Vaccinium uliginosum (Anarta cordigera Thnbg., Lithophane lamda F., Colias palaeno L.). Ecological grouping of peat bog Lepidoptera : stenotopic species 1. Tyrphobionts (Prus, 1932 ; Spitzer, 1975 ; ROHACEK, 1982 ; MEINEKE, 1985 ; MıkKkoLA & SPITZER, 1982 ; GELBRECHT, 1988, etc.) are obligatorily associated with peat bogs in temperate and southern boreal zones. Their most important ecological requirements are micro (meso) climatic and edaphic conditions (Zugraphe subrosea Steph. is a typical example, Fig. 2). Some bog Lepidoptera are closely associated with the habitat because of their foodplants (e.g. strictly monophagous species that feed on Ledum palustre, Vaccinium uliginosum and Eriophorum vaginatum). In some cases monophagy is recent, induced by the Holocene vegetation succession, which resulted in the extinction of certain plants (see Spitzer et al., 1991 — Eupithecia gelidata Möschl.). There is a general trend to a weaker tyrphobiontic association towards the northern and alpine timber lines (MIKKOLA & SPITZER, 1982). 2. Tyrphophilous biotas are plants and animals that are not restricted to peat bogs. Such peatland species colonise other wetlands, wet forests, heathlands 46 Fig. 2. Larva of Eugraphe subrosea (Steph.), a local geographical race of the Mrtvy luh bog, Sumava Mts. and meadows, but achieve their greatest population abundance in peat bogs (see PEus, 1932 ; Lepidoptera are listed by Spitzer, 1975 ; 1981 ; MıKKoLA & SPITZER, 1975 ; GELBRECHT, 1988). Why is a peat bog “island” unique? The recent habitat island structure of central European bogs is a unique product of the ecological succession in the Holocene. The relict biotas of bogs, plants and invertebrates especially, have lived here from the early Holocene or even the late Glacial stadials (PEus, 1932 ; Cooper, 1970 ; JANKOVSKA, 1980). Such organısms are very vulnerable to extinction because they do not occur in other habitats. Changes in the local environment (water level, chemistry of water and peat, etc.) of a peat bog can cause the extinction of the local tyrphobiontic taxa associated with a particular habitat island. Such changes are irreversible because it is not possible to recreate the evolutionary history that gave rise to the biodiversity of a specific bog. A good example is the recent fate of subalpine bogs in the Krkonoëe Mountains, which 14 years ago were sprayed with insecticide to suppress a forest pest. The relict and endemic (subspecies) insect fauna probably disappeared (e.g. Pachnobia alpicola (Zett.) a tyrphophilous relict noctuid of the subalpine zone). The habitat is now irregularly colonised by some opportunistic insect species. Insecticides and other chemicals are likely to prove fatal to the existence of such tyrphobiontic insect communities. 47 Conclusions for conservation management The best conservation strategy for peat bogs and their Lepidoptera communities is a “no action strategy” — other than preserve good hydrological conditions. Generally, the hydrology is the most important factor. The bog ecosystem is fragile and any human impact is likely to prove fatal for some components of the fauna and flora. Species of Lepidoptera are the best bioindicators. Moni- toring of the hydrological and other environmental conditions is necessary, if a bog is situated in a predominantly man made landscape. Rules for conservation of central European peat bogs : l. Maintain the hydrological conditions that prevent successional change from wetland to closed pine forest. Wet edaphic “forest-tundra” formation appears to be the optimal state (see also MEINEKE, 1985). 2. Ban the use of chemicals (insecticides, herbicides, etc.) close to the localities. 3. Conserve all of the “habitat islands”. For example, in the case of the unique “archipelago” of peat bogs in the Sumava Mountains (see WELLS et al., 1983 ; SPITZER, 1981) the whole archipelago needs to be conserved. Scientific and educational values of peat bog communities of Lepidoptera It is difficult to separate the “educational” from the purely “scientific” value of central European bogs. The following scientific and educational priorities should be included in the scientific conservation programme : 1. A model study of habitat islands and their relict Lepidoptera communities based on the theory of island biogeography. 2. The use of peat bogs as sites for testing s-selection (stress tolerant taxa) and r- and K-selection hypotheses. 3. Studies of relict endangered species of Lepidoptera and their subspecies. 4. Evolutionary differentiation of the insect populations within and between “archipelagos” of bogs (e.g. Colias palaeno L. and Eugraphe subrosea Steph.). References Husticy, I., 1966.

The first involves servicing a national network of recorders which was set up in the winter of 1990/91 to trawl information on the current national distribution, status and conservation requirements of the rarer species of macro-moths in Britain. The information collected is being used to organise surveys and produce national surveys and produce national distribution maps, data sheets and a bibliography for the rarer moths. The rarer macro-moths have been defined as those species believed to occur in less than one hundred of the 10 km squares in Britain. Approximately 280 of the 730 or more macro-moth species that breed in Britain are in this category now. The collected information is used by the government conservation agencies to identify important breeding sites and advise on their management. Since its inception in 1987 the Moth Conservation Project has also been involved in devising and assisting practical conservation measures for anumber of rare moths including six species of moths which receive legal protection in Britain and are listed on Schedule 5 of the Wildlife and Countryside Act 1981 and 1988 amendment. These six are Zygaena viciae argyllensis Tremewan, Thetidia smaragdaria maritima Prout, Pareulype berberata Denis & Schiffer- müller, Siona lineata Scopoli, Acosmetia caliginosa Hübner and Hadena irregularis Hufnagel. Practical conservation measures for these species include site protection and defence, management work, ecological studies, captive breeding and translocation to establish new breeding colonies. The Moth Con- servation Project also liaises with and promotes the work of a large number of other organisations and individuals involved in moth recording and con- servation to raise public awareness and provide a national overview. Introduction This paper reports on the work of the Moth Conservation Project which was started by the Nature Conservancy Council (NCC) in 1987 and subse- quently passed to one of its four successor organisations, the Joint Nature Conservation Committee (JNCC) following the reorganisation of the UK 51 government conservation agency in April 1991. The JNCC is the UK govern- ment agency responsible for promoting nature conservation at the UK and international levels and is the coordinating body for the three separate country agencies of England (English Nature), Scotland (Scottish Natural Heritage) and Wales (Countryside Council for Wales). The author has been responsible for the Moth Conservation Project since its inception and the work has consisted of four main tasks. These are: — to identify which species are where, keep the information up to date and actively encourage recording effort ; — draw up a list of the species in greatest need of conservation ; — organise, coordinate and promote practical conservation measures ; — promote greater awareness of moths and other invertebrate animals and their value as indicators of habitat quality and change. Details of these activities have been provided by WARING (1988a ; 1989a,b,c ; 1990a,b,c ; 1991a,b,c,d ; 1992a,b,c) and references contained therein. This paper is intended as a summary and guide. Locating and documenting the resource In Britain there is a long history of recording moth distribution and abundance. Fust (1868) provides an early account of the distribution of moths in Britain. More recently the late John Heath (based at the Biological Records Centre (BRC), Institute of Terrestrial Ecology, Monks Wood) organised a national recording scheme and this has formed the basis for the distribution maps which have been published in HEATH & EMMET (1976-1991). The recording scheme was discontinued due to lack of resources on the retirement of John Heath in 1982. There has been no decrease in the amount of voluntary recording effort however. The author estimates that several thousand light- traps are operated by private individuals and organisations each year in Britain and covering many more locations. There is a strong tradition of local recording which extends back more than two hundred years. For consistency local schemes are usually based on the Watsonian vice-county system which continues to be strongly advocated (Morris, 1990). Local lists continue to be published on a regular basis and often provide information on the habits and phenology of species. Increasingly the county lists are including distribution maps as well. CHALMERS-HUNT (1989) provides a recent bibliography of local lists. In addition the Rothamsted Insect Survey continues to maintain a network of nearly one hundred light-traps which are operated every night of the year throughout Britain. So far it has not been possible to set up a national recording scheme again that is capable of processing all the moth data that is being collected in Britain. At the same time conservation organisations frequently require greater detail about the occurrence of certain species than the basic grid reference and date class collected by John Heath’s scheme. To provide the information required in conservation issues the By 2 Nature Conservancy Council developed the Invertebrate Site Register (ISR) in 1979, with computerisation of the data-base from 1986 onwards. The ISR aims to maintain files on all UK sites of known invertebrate importance and to supply information about the species of conservation interest for use in site evaluation, protection, defence and management. Currently the ISR holds files on some 8500 sites. Many sources of information have been trawled to prepare short-lists of species which are nationally rare, restricted to particular habitats or are of conservation interest for some other reason, such as a population subject to long-term study. The ISR stores and retrieves this information. The data can be accessed by species rather than by site to allow compilation of a list of sites at which a particular species has been recorded or for production of a distribution map. HADLEY (1983 ; 1984) was the first to compile a list of the nationally scarce macro-moths. This was produced by using the BRC maps and by drawing on the experience of active field workers in the major British entomological societies. For the macro-moths, which may be regarded as those species included in SKINNER (1984), the nationally scarce species were defined as those recorded since 1960 from less than one hundred of the 10km squares in the Ordnance Survey National Grid which covers the UK. This amounted to some 256 species. HADLEY (1983) also drew on local lists to define additional species of regional interest. Since then information on these species has been entered on the ISR. A Red Data Book (SHIRT, 1987), compiled at the same time and published in 1987, lists the species recorded from fifteen or fewer of the 10km squares and categorises these as endangered, vulnerable or rare on the basis of known threats to the sites in which they occur. This list includes 99 species or subspecies of macro-moths. The Moth Conservation Project has been able to draw on the above publications and on the facilities and data in the ISR. The first step was to issue a list compiled from Hap ey (1984) and Shirt (1987) and trawl in the data on these species from the years since 1980. This information has been used to compile up to date distribution maps and see if the species still merit their existing conservation status. Information on a further 80 localised species was also requested to assess whether any had moved into the nationally scarce category based on their status from 1980 onwards. The information was collected by contacting all existing county recorders, active field workers and by extracting records from the national entomological journals. In addition the Rothamsted Insect Survey kindly supplied copies of their records on disc and the Biological Records Centre have provided their data which enables comparison of distributions pre- and post-1980. At the time of writing, virtually all the data required for production of maps of the scarce species has been entered onto computer and maps such as Fig. | are being prepared for circulation to recorders for checking. This new generation of maps uses 1980 onwards to distinguish recent records and larger spot sizes to indicate multiple records of adults from the same 10 km square or evidence of breeding such as reports of immature stages. This is intended 3) to focus attention on breeding colonies and distinguish them from records which may refer to vagrant specimens. The current generation of recorders is not in the habit of sending in details of numbers of moths seen and is mainly oriented to work with light-traps but it is hoped that the new maps will promote valuable work on larvae. At present it is true to say that much more information is being collected from the field than the national organ- isations are capable of trawling and processing and that the latter have been the weak link in the chain. During 1992 it is intended that an Atlas of up to date distribution maps and an accompanying text will be prepared for JNCC. This will make available the information collected so far. Preparation of a list of nationally scarce macro-moths The new maps will be used to define the current nationally scarce species. It is quite clear from the results that some species have increased and others have declined in range dramatically in the last ten years, even allowing for possible differences in recording effort and coverage. A good example is that of Thera juniperata. Since the last distribution map of this species was published (in WARD, 1977), T. juniperata has extended its range greatly, in part dispersed as immature stages on young juniper bushes (Juniperus spp.) which have become popular with gardeners in the Midland counties and elsewhere (WARING, 1992b). The current situation (Fig. 1) is very different from the mid-1970s and before, when TZ: juniperata was largely confined to parts of Scotland and to the chalk of south-eastern England. Some species have expanded their ranges greatly over the same time span, such as Rhyacia simulans, with no apparent assistance from man, while others have declined. Published map information and recording effort has sometimes proved to be a less than adequate indication of the real situation. The map of Cucullia lychnitis in HEATH & EMMET (1983) shows records from only three 10 km Squares in mainland Britain since 1960. A survey of this species in 1991 (WARING, 1992c) discovered post-1960 records from several other localities and that the species has bred in at least sixteen 10 km squares since 1980. It was found to be occupying almost all of these in 1991. Practical conservation measures for nationally scarce species National reviews and mapping projects are on-going but can become ends in themselves. The purpose of NCC and JNCC involvement has always been to use these as tools to launch and sustain practical conservation measures for the species in greatest need. When the Moth Conservation Project was started in 1987 the rarest species of macro-moth had already been identified and five of the species listed in SHIRT (1987) as endangered had been given legal protection from collection and sale since 1981 under the terms of Schedule 5 of the Wildlife and Countryside Act of 1981. A sixth species had been proposed for inclusion in the quinquennial review of 1986 and was added in an amendment to the Act in 1988. A first priority in 1987 was to investigate the current status of the protected species on the ground. 54 i Thera juniperata Linnaeus O Before 1980 1980 Onwards B Larval record ® Several adult records © Single adult record Fig. 1. The distribution of Thera juniperata L. in Britain. SB) Siona lineata Within weeks of starting the post, work commenced on Siona lineata. This species is now confined in Britain to two fields of rank grassland in Kent although in the past it was more widespread (WARING, 1988a ; 1990a). The local NCC office had been sent a copy of a paper in draft which had been submitted to a leading British entomological journal by a highly respected entomologist complaining about the mis-management of part of one of the two remaining sites which is a National Nature Reserve. Sheep had been allowed to hard-graze part of the site and had reduced the turf height to less than 2 cm. which entomologists consider is much too short to provide suitable conditions for the moth to breed. Meetings were held with the regional staff responsible for the reserve and with the author of the draft. It soon became clear that although numbers of the adult moth had been counted annually since 1976 on a transect walk used for monitoring butterfly populations on the site, the ecological requirements of the moth and its immature stages were poorly known. The larval food-plant in the wild was generally considered to be Brachypodium pinnatum, upon which wild females had been seen laying and it was also considered that the tussocks of this plant probably provided important over-wintering refuges for the larvae. These impressions have had major implications when determining and reviewing the management of the site. The hard-grazing of part of the site had been an accident caused when sheep were penned there because of problems with stray dogs elsewhere on the site. In other parts of the reserve B. pinnatum was rampant to the virtual exclusion of other herbs and grasses. The moth was now absent from the hard-grazed site and dwindling in numbers elsewhere for unknown reasons. Other entomologists were contacted immediately and it became apparent that no one had reared S. lineata successfully in captivity in Britain, at least not recently, in spite of several attempts supplying both grasses and dicotyledonous herbs. A literature search suggested that the latter was the more likely pabulum (e.g. SCORER, 1913 ; Skou, 1986). Field observations that summer confirmed the habit of ovipositing on B. pinnatum and other grasses and some eggs were collected for rearing. In a choice experiment newly hatched larvae were offered the range of common herbs available at the breeding site. From these they selected Origanum vulgare upon which they proceeded to develop. As the larvae grew in size they were transferred to as near natural conditions as possible, using potted turves from the site. The potted turves were enclosed in nets out of doors and the larvae were released into these before the winter to study their habits. Overwintering was successful and seven larvae were reared to adult on O. vulgare. Subsequently larvae have been found in the wild in association with damaged leaves of O. vulgare upon which they have fed. B. pinnatum appears to be important in providing daily roosting and basking sites for the larvae, which match the dry stems in colour, and in providing spinning sites for the zygaenid-like spindle-shaped cocoon this species produces. Full details and photographs of this work are given in WARING (1988a ; 1989a and 1990a). 56 Following the ecological work, the management of the parts of the site which the moth occupies has been modified to create a balance between sufficient B. pinnatum and abundant O. vulgare. In 1991 numbers of adult moths counted on the transect walk were higher than in any year since 1979 (Fig. 2), although this is probably the result of the dry weather and high temperatures experienced in 1990/91 as well as the management.

The number of Siona lineata Scop. adults seen at one of the two known localities in Britain between the years 1976 and 1991. Other work on S. lineata during the project has included monitoring the effects of an accidental fire which burned 10% of the site of the second remaining colony. It has been demonstrated that the moth will recolonise an area burned in May as early as the growing season of the following year, at which time adults have been seen ovipositing and the resulting larvae located later in the year. Searches for the moth in other fragments of rank chalk grassland elsewhere in Kent and in possible former localities in Dorset and Somerset have been organised but the moth has been found at none. Management to recover a former site in Kent at which the moth occurred up to 1984 has been set in motion and the second of the two known colonies has been Dj scheduled a Site of Special Scientific Interest (SSSI) which confers a measure of protection from changes in land use under the terms of the Wildlife and Countryside Act 1981. All five of the other Schedule 5 protected species have been given attention. Acosmetia caliginosa A. caliginosa had not been seen since 1984 and seems to have died out from both of its last known sites which were the edges of rides in conifer plantations on the Isle of Wight. The moth was described in NCC files as a creature of woodland rides and requiring sensitive ride-side management. Surveys for the moth were organised in 1987 (for larvae) and 1988 (for adults) and these covered former sites and a number of others known to support the larval food-plant Serratula tinctoria. A strong colony of the moth was discovered surviving on a site from which it had been reported nearly forty years previously and the breeding grounds were found to extend into a neighbouring property (WARING, 1990a,b). Both of these sites are open heathland and the larvae have since been found on plants of S. tinctoria growing in full sun amongst sparse vegetation — a much drier and warmer situation than the lush conditions which now exist in the edges of the plantation rides. As with S. lineata, this single discovery has profound implications for management and the shade from conifers and scrub is now seen as a major threat to the species. At one of the former sites scrub invasion has been cleared and nearly 800 larvae were reared and released in 1989 in an experiment to see if a colony can be established. The larval food-plant is now abundant and adults produced by the original larvae were recorded at light-traps in 1990. No adults were found when light-trapping took place in 1991 but this coincided with an extended period of adverse weather during which many species known to be resident were not recorded. Light-traps will be operated at the site again in 1992. The knowledge gained during this study indicates that this is currently a sub-optimal site. Owing to the small size of this woodland clearing and the proximity of trees and shrubs, it has been necessary to coppice the site every second winter to control the woodland regeneration and in spite of this treatment conditions at this site differ substantially from the surviving breeding grounds on heathland. The situation will not be resolved without clearance of a much larger area and use of domestic animals or other means to keep woody growth at bay. Interest in establishing colonies of A. caliginosa continues, with the aim of replacing colonies that have been lost because of adverse management in the last forty years and because the species now appears to be restricted to what is basically one locality. The possibility of a return of the insect to the mainland, from which it was last seen in 1961, is being investigated by English Nature as part of their Species Recovery Plan. Meanwhile negotiations are underway to maintain and improve management at the remaining colony. Some adjacent scrub has been cleared to extend the size of the breeding grounds and further scrub clearance followed by rotational management is planned. 58 Pareulype berberata The third of the Schedule 5 species, Pareulype berberata, was formerly wide- spread in Britain and reached at least as far north as Yorkshire (WARING, 1989a,b ; 1990a ; 1991c) although there is also a record from Scotland. During the late nineteenth century it was discovered that the larval food-plant, Berberis vulgaris, was a host of the wheat rust Puccinia graminis and there began an extensive campaign to eradicate B. vulgaris from field hedgerows and wood margins and this resulted in the loss of colonies of the moth (BARRETT, 1902). There is evidence that the practice of Berberis destruction continues today to some extent even though modern wheat strains are resistant to the rust. Additional losses have been caused by general grubbing out of hedgerows to increase the size of fields to accommodate modern farming methods and by fires resulting from badly controlled stubble burning (WARING, 1989b ; 1991c). By the late 1970s the moth was apparently reduced to a single colony in Suffolk. This colony, which has been known since the 1860s (WARING, 1989b), has been eroded in size as bushes have been removed to accommodate improvements in nearby roads. During the 1970s the whole site was threatened with obliteration because it was in the proposed route of a new by-pass. Fortunately the eventual route taken by the by-pass narrowly avoids the site. In 1983 vandals started a fire which scorched some of the best bushes. Because of the precarious nature of this remaining colony a captive stock was established from a single female captured in May 1988. This stock has been used in three establishment trials aimed at setting up new colonies. The discovery in 1991 of larvae of a successor generation at one of the establishment sites suggests that the trial may be on the way to success. The necessity of such extreme and time-consuming measures for these species was emphasised in August 1991 when an accidental fire at the donor site burned 73% of the Berberis at this colony at a time when the larvae were feeding. The entire standing volume of Berberis before the fire was estimated to occupy only 120 m? (WARING, 1989b) and there is currently doubt as to whether any P berberata have survived to recolonise the site if and when the Berberis recovers from the fire. Arrangements are underway to propagate new bushes to replace those that have been lost over the years. Meanwhile a second colony of the moth has been discovered by investigating old records of occasional adults taken at light in Gloucestershire (WARING, 1991c) and arrangements have been made to protect these breeding grounds. Surveys of a number of other sites with the potential to support colonies have been conducted (e.g. WARING, 1992a), so far without finding any more colonies. However the capture of a single adult female at light in 1990 in Hampshire suggests that at least one undiscovered colony survives so the search will continue. Zygaena viciae and Thetidia smaragdaria Two more of the Schedule 5 species are Zygaena viciae and Thetidia smaragdaria. Both of these have been covered by extensive surveys, monitoring of their single known colonies and ecological studies which are still underway. 59 Further details are provided by BARBOUR & WARING (1991) and WARING (1989c ; 1990c). The latter species has been the subject of a major captive rearing programme aimed at building up numbers of larvae for return to the wild. This has not been an easy job with this species. Whereas it was possible to produce over 1000 larvae from a few A. caliginosa females within one generation, 7: smaragdaria has been much less accommodating. During 1987 only eleven larvae were found in the wild after a major survey of the Essex and Kent salt marshes to which this species has always been confined in Britain. These were used to establish a captive stock (WARING, 1989c). The females are capable of laying only 70 or 80 eggs as a rule and it has been our experience that many lay fewer or none. From eleven pre-hibernation larvae in autumn 1987 numbers have been raised in captivity to over 100 in autumn 1988 and over 600 in autumn 1989. In 1990 the captive stock was dispersed between several entomologists skilled in breeding moths and arrangements were made for releases of the progeny into the wild. However breeding success was extremely poor and resulted in just over 100 larvae only in autumn 1990. From the resulting adults over 400 larvae were reared in autumn 1991 and at least 350 have survived the 1991/92 winter. This is barely sufficient for establishment trials and many fewer than we would have expected after five years of hard work and much care. The reason for such poor reproductive success, which is a common experience among those maintaining captive moth populations, is usually attributed to inbreeding. There is no denying that the captive stock of T: smaragdaria is inbred. Neither of the two colonies that have been recorded in the last fifteen years have numbered more than 100 larvae at any point during this time so inbreeding has been inevitable. Another reason for the poor reproductive success could be a build up of pathogens in these small inbred populations. Larvae have been reared at low density on new potted food-plants each year and have not displayed the characteristic symptoms of viral diseases. In fact larval mortality has been very low in each generation. The poor reproductive success stems from the fact that many adults fail to pair or pair but produce few eggs or infertile ones. Arrangements are being made for specialists to examine the stock for protozoan and viral infections during 1992. One technique for reducing the possibilities of virus transmission is to surface-sterilise the eggs with a dilute solution of formaldehyde and in 1991 this was applied to a small batch of eggs to establish whether 7. smaragdaria eggs would survive this treatment. The hatch rate was very poor in both the treated sample and a control batch from the same females. This treatment greatly increases the time that has to be spent on the culture. Protozoan infections can be controlled using drugs sprayed onto the food-plant for the larvae to ingest. Depending on the results of the examinations for pathogens, these treatments may be applied to part of the captive stock in the future. Meanwhile the numbers of larvae found in late summer counts at the last- known wild colony in Britain have declined from 56 in 1988 to 27 in 1989, 28 in 1990 and none in 1991. The causes of loss of previous colonies have been variously attributed to land reclamation, sea-wall construction and main- 60 tenance, removal of large numbers of larvae by insect collectors, crowding of the larval food-plant, Artemisia maritima, by coarse grasses and tramplıng by domestic livestock. There is no evidence that any of these factors are responsible for the decline at the last-known colony, although a fire narrowly missed wiping out the colony in 1989. Could it be that such small colonies, reduced to fragments of their former habitat, can ultimately become too inbred or disease-laden to remain viable even if their immediate habitat remains suitable? Hence the importance of the pathogen tests. Hadena irregularis The latest addition to the list of moths to be given legal protection in the UK, Hadena irregularis, was added to Schedule 5 in 1988. The same year a major survey was organised covering all the known sites for the larval food- plant, Silene otites, which has been the subject of botanical surveys in recent years. The plant is confined to the East Anglian Breckland area. No larvae were found. A second survey, in 1989, covered the most promising areas again but with negative results. Subsequent enquiries indicate that the moth had almost certainly declined to extinction some years before it was proposed for inclusion on Schedule 5. The last known sighting was in 1977. This case draws attention to the need for improved and continuous monitoring of the rarest species so that the current status is always known. With only irregular surveys and out of date information species are being lost before we have time to realise and react to their decline. Other work While this account has concentrated on the Schedule 5 species, the breeding grounds of many other rare moths have been visited during the last five years. Surveys have been organised and assistance given in protecting and managing sites all over the UK, from the steep coastal slope inhabited by Z. viciae argyllensis in western Scotland to the sand-bank occupied by Luperina nickerlii leechi in the extreme south-west of England, the estuary on the coast of eastern England where Gortyna borelii resides, to the bog in west Wales where the larvae of Eugraphe subrosea are counted every year. The responses of moths to various types of management such as coppicing and conifer planting in ancient broad-leaved woodland, fenland management and the harvesting of wild-flower seed in hay-meadows have been examined (WARING, 1988a,b ; 1989d ; 1990d ; WARING & HAGGETT, 1991). A large number of independently organised moth recording and conservation projects have been promoted via publications and radio and television broadcasts and it is apparent that moths and moth conservation enjoy a higher profile now than at the inception of the project. 61 The future for moth conservation in the UK Central to the development of moth conservation in the 1990s is the need to find means of sustaining a long-term programme of action. Conservation efforts remain piecemeal and sporadic, sometimes subject to the vagaries of funding but more often critically dependent on the enthusiasm and time of highly motivated local volunteers. The latter are the most valuable conservation resource. Much can be achieved simply by providing a national overview in the context of which the importance of particular local projects can be seen and attention focused. Local action groups thrive on encouragement and the realisation that what they are doing is recognised to be of value by others outside the group. There is no doubt that county-based recording will continue to thrive and that more detail will be recorded as computers and other aids make it easier to process and retrieve this information. This will be of increasing use in local conservation issues. However a national recording scheme is needed to encourage recorders to poorly worked areas and to aid the interpretation of local data. Hopefully the production of the Atlas of rarer moths will stimulate many more local projects but past experience with the Red Data Book (SHIRT, 1987) suggests that this alone may be insufficient to ensure that the rarer species are conserved. Promoting recording and making recommendations for action is one thing, the logistics of ecological study and practical conservation measures can rapidly require full-time commitment to achieve even modest progress. Within the conservation organisations staff that are able to build such projects into their work programme for a few days or weeks per year and contractors and researchers wishing to tackle these jobs also find an up to date national information network useful to quickly locate other colonies or experience. This is apparent from the number of enquiries the author receives. With so much of this service now in place it is hoped that ways and means can be found to continue and build upon it in the years to come. As it is increasingly realised that moths are sensitive indicators and integrators of habitat quality and change in our environment, and as the large-scale declines of some species become more widely known, public support for the monitoring and conservation of moths will grow in the same way that it has for butterflies. The scientific value of conserving the isolated British populations for study by evolutionary biologists, ecologists and taxonomists hardly needs stating, particularly as some of the British forms are recognised as separate subspecies from those of continental Europe. One of the above species, P berberata, has been collected as long series from the same site in Britain over many years, beginning in the 1860s when the colony was first discovered. In fact the great majority of specimens in British collections come from this one site. It is likely that such a wealth of preserved dried material of known origin and date will be of value to many disciplines, not just geneticists and entomologists in the future. But unless special conservation measures continue to be taken now, these populations and the link with the past will be lost. It is also true to say that for too long moth recording and conservation in Britain has proceeded with an imperfect 62 knowledge of the situation elsewhere in Europe. The case of S. lineata is a good example. There must be many other cases where the biology of particular species is better known or can be more easily studied abroad, although the habits of 7: smaragdaria indicate that the results may not always be applicable in Britain. Greater contact with workers in other European countries is desirable and Societas Europaea Lepidopterologica is the obvious medium.

Summary Twenty-four butterfly and three skipper species were collected at Kuujjuarapik (S5°17 N, 77°48’W), in the forest tundra zone of northern Québec, in 1985, 1990 and 1991. This material markedly extends the known northern limit of many species, including Clossiana bellona (Fabricius, 1775), Vanessa atalanta (Linnaeus, 1758), Incisalia polios Cook & Watson, 1907, Polygonia gracilis (Grote & Robinson, 1867), Lycaeides idas (Linnaeus, 1761) and Celastrina ladon (Cramer, 1780). A massive migration of Vanessa cardui (Linnaeus, 1758) was observed in 1991. Certain northern species, such as Colias nastes Bois- duval, 1832 and Clossiana polaris (Boisduval, 1828), are at their southern limit at Kuujjuarapik. The total fauna on the eastern coast of James Bay - central Hudson Bay, Québec (between 51°30’ and 57°15’N; up to 100 km inland of the coast) comprises 41 species of butterflies and skippers. The proportion of circumpolar (Holarctic) species increases with the latitude. The approximate percentage of Holarctic species at James Bay sites is 50%, at Kuujjuarapik 75% and at more northern sites on Hudson Bay 90%. Introduction The Lepidoptera fauna of the eastern coast of Hudson Bay is rather poorly known. Thus, in the recent handbooks by LAPLANTE (1985) and ScoTT (1986), the maps and other data on the distribution of butterflies in Nouveau-Québec are highly generalized. Only a few papers on the butterflies of the eastern coastal area of Hudson Bay and of James Bay have been published (FREE- MAN, 1949; LAFLAMME & PERRON, 1983; GAUTHIER & KOPONEN, 1987 ; CoMToıs & NÉRON, 1987 ; LAYBERRY, 1988 ; NERON, 1990 ; KOPONEN, 1992). No detailed study of the butterfly fauna of any restricted locality in the Hudson Bay area is available. (!) Present address : Zoological Museum, University of Turku, FIN-20500 Turku, Finland 65 This article presents the butterfly and skipper species found by the author around the village of Kuujjuarapik (Whapmagoostui/ Poste-de-la-Baleine/ Great Whale) during three summers (1985, 1990 and 1991). Data on their flying periods and habitat preferences in the area are given. The known butterfly and skipper fauna of the southeastern coasts of Hudson Bay is also discussed. Study area, material and methods The Kuujjuarapik area (55°17 N, 77°48’°W) belongs to the southern forest tundra zone (PAYETTE, 1983) (Fig. 1). Three conifer tree species, white spruce, black spruce and tamarack grow there at their arctic-maritime limit. Alder and dwarf birch shrubs are typical of the area. There are also small bogs and moist meadows. Open hills, barren or covered by alpine heath, are rather low, the highest summit being about 230 m. Vast alpine tundra areas are absent around Kuujjuarapik. The village is located on a sandy terrace between the Great Whale River and Hudson Bay. Butterflies and skippers were collected and observed around the village. Lepidopterans were observed in 1985 whenever the weather permitted ; species were caught by netting, and abundant ones also recorded without catching. The study period consisted of two periods, 18th June - 8th July and 2nd August - 2nd September 1985 ; the total number of observation days was 34. In 1990 collecting was less intensive ; the main observation period was 13th July - 21st August, but some collecting was also done around mid-June. The collecting period in 1991 was short, 5th-11th July. The author collected butterflies at Lake Ekomiak (53°23’N) 60 km south of Radisson (La Grande) in July 1990, and between Rupert River (51°30'N) and Lake Ekomiak on the James Bay Highway in July 1991. Information on collections by LAYBERRY (1988 and unpubl.) in 1986-87 in the James Bay Highway area (between 51°30’ and 53°45’N), has been included in this paper. Collections between 53°10’ and 57° 15'N, presented by GAUTHIER & KOPONEN (1987), are also included. The system and nomenclature is mainly based on LAPLANTE (1985) ; however, all subspecific and other infraspecific names have been omitted. Results 1. Fauna of Kuujjuarapik Altogether, 24 species of butterflies and three skippers were found at Kuuj- juarapik (Table 1). The butterfly material included twelve Nymphalidae, five Lycaenidae, four Satyridae and three Pieridae species. Most species were collected or observed frequently ; only /ncisalia polios Cook & Watson, 1907 and Speyeria atlantis (Edwards, 1862) in 1985, Colias nastes Boisduval, 1832 in 1990, and Clossiana bellona (Fabricius, 1775), in 1991, were observed once. The species observed most often in 1985 were Epidemia 66 dorcas (Kirby, 1837), which was seen on 20 of the total 34 observation days, and Lycaeides idas (Linnaeus, 1761) (18), both flying mainly in August, Colias pelidne Boisduval & Leconte, 1829 (14) with a very long flying period, Oeneis taygete Geyer, 1830 (14) and Celastrina ladon (Cramer, 1780) (13) flying in June-July. Nymphalis antiopa (Linnaeus, 1758), Clossiana titania (Esper, 1793), ©. selene (Denis & Schiffermüller, 1775) and C. frigga (Thunberg, 1791) were also seen frequently. Three species not found in 1985 were collected in 1990 : Colias nastes, and the skippers Hesperia comma (Linnaeus, 1758) and Pyrgus centaureae (Rambur, 1839) ; and one in 1991: Clossiana bellona. The skippers were markedly abundant, and their absence in 1985 is presumably due to their flying pattern : only or dominantly in even years at Kuujjuarapık. The same is true for Clossiana polaris (Boisduval, 1828). A massive migration of Vanessa cardui (Linnaeus, 1758) was observed in July 1991. More than 20 specimens were seen at Kuujjuarapik and five captured, Sth-11th July. Moist swampy meadows were the preferred flying sites of many species at Kuujjuarapik. Species collected frequently in moist meadows and bogs were Clossiana frigga, C. freija (Thunberg, 1791), C. titania, Proclossiana eunomia (Esper, 1799), Oeneis taygete, O. jutta (Hübner, 1806), Coenonympha inornata Edwards, 1861, Epidemia dorcas, Carterocephalus palaemon (Pallas, 1771), Hesperia comma and Pyrgus centaureae. Species typically observed in forested sites were Nymphalis antiopa and Polygonia gracilis (Grote & Robinson, 1867), and also Clossiana titania and Lycaeides idas. Some species, such as Vanessa atalanta (Linnaeus, 1758), Colias pelidne, Clossiana polaris, Agriades franklinii (Curtis, 1798), Oeneis taygete and O. melissa (Fabricius, 1775) were often seen on open, windy hills and also on the open Hudson Bay shores. The most eurytopic species at Kuujjuarapik seemed to be Colias pelidne, Pieris napi (Linnaeus, 1758), Clossiana selene, C. titania, Vanessa atalanta, Lycaeides idas, Celestrina ladon and Hesperia comma. 2. Fauna of the eastern coast of James Bay - Hudson Bay Altogether, 41 butterfly and skipper species are known from the coastal area between southern James Bay and central Hudson Bay (Table 1). This area is situated between Rupert River, 51°30’N, and Lake Minto, 57° 16N (Fig. 1). Thirteen species not caught at Kuujjuarapik in 1985, 1990 and 1991 are known from the James Bay area. Papilio machaon Linnaeus, 1758 and the migrating Danaus plexippus (Linnaeus, 1758) were mentioned by FREEMAN (1949) from the southernmost locality included, Fort Rupert (Waskaganish). The same is true for Incisalia augustus (Kirby, 1837), reported by LEBLANC (1985) at Rupert River. Other species, known to occur in the James Bay area (Lay- BERRY, 1988 ; SCOTT, 1985), but not found by the present author include Colias interior Scudder, 1862, Oeneis chryxus (Doubleday & Hewitson, 1849), Erebia disa (Thunberg, 1791) and Epidemia epixanthe (Boisduval & Leconte, 1833). 67 Labrador.” / VV Newfoundland Ontario = se ood x I — Fig. 1.

The author collected the skippers Polites mystic (Edwards, 1863), Erynnis icelus (Scudder & Burgess, 1870) and Thymelicus lineola (Ochsenheimer, 1808) at Rupert River, the southernmost study site. Of these, 7: lineola, an introduced European species, was abundant. Pterourus glaucus (Linnaeus, 1758), Phy- ciodes morpheus (Fabricius, 1775) and Basilarchia arthemis (Drury, 1773) were caught as far north as Lake Ekomiak (53°23'N). Vanessa cardui occurred in great numbers along the James Bay Highway at all suitable sites in early July 1991 (see KOPONEN, 1992). Of the 41 species found between Rupert River and Lake Minto, 27 have been observed by the present author at Kuujjuarapik. The number of species caught at the James Bay sites, north of Rupert River, is 32 and 19 are known from the northern forest tundra, between Richmond Gulf (17 species) and Lake Minto (Table 1). Discussion l. Kuujjuarapik Up to now, 17 butterfly species have been reported from Kuujjuarapik (FREE- MAN, 1949; LAFLAMME & PERRON, 1983 ; GAUTHIER & KOPONEN, 1987 ; NÉRON, 1990). The present material includes all of these, plus the following seven butterflies which have not been found earlier at Kuujjuarapik (see Koronen, 1992) : Colias nastes, Clossiana bellona, Speyeria atlantis, Vanessa atalanta, Polygonia gracilis, Incisalia polios, and Celastrina ladon.

The observation periods at Kuujjuarapik were 18th June - 8th July and 2nd August - 2nd September 1985, mid-June and 13th July - 21th August 1990, and Sth-11th July 1991.

According to LAPLANTE (1985), many of the present species have a southern range in Québec, and their occurrence at Kuujjuarapik on the Hudson Bay coast is somewhat unexpected. LAPLANTE (1985) regarded Clossiana bellona, Vanessa atalanta, Incisalia polios, Speyeria atlantis and Carterocephalus palaemon as species of the temperate-boreal forest zone. GAUTHIER & Koronen (1987) already reported C. palaemon from Richmond Gulf, north of Kuujjuarapık. The following species also have a southern (boreal) distri- bution ; their range, according to LAPLANTE (1985), in the Québec-Labrador peninsula extends to the forest tundra area only in its maritime southeastern part on the Labrador coast (see LAPLANTE 1985: 218-219; note that Fort Rupert in his map on p. 219 should be Fort George) : Nymphalis antiopa, Polygonia gracilis, Epidemia dorcas, Lycaeides idas and Celastrina ladon. Of these, NERON (1990) has already reported Nymphalis antiopa and Epidemia dorcas from Kuujjuarapik. Many of the above southern species have been reported from comparable areas on the western coast of Hudson Bay in Ontario and Manitoba (RIOTTE, 1971 ; KLASSEN, 1984 ; KLASSEN et al., 1989). Danks (1981) mentioned Clossiana polaris, Colias nastes and Agriades frank- linii as butterfly species occurring in the Canadian High Arctic. Of the northern species, Colias nastes, Clossiana polaris and Oeneis melissa seem to reach the southern limit of their range around Kuujjuarapik. Oeneis polixenes (Fabricius, 1775) has been collected north of Kuujjuarapik (GAUTHIER & KOPONEN, 1987). Its absence from Kuujjuarapik is probably explained by the absence of large- scale tundra areas around the village. The special flying pattern, only or predominantly in alternate years in the north (cf. Scott, 1981 ; Ferris et al., 1983) can explain the uneven occurrence of some species in 1985 and 1990. Thus Clossiana polaris (only one specimen in 1985 and none in 1991), and Hesperia comma and Pyrgus centaureae (not found in 1985 or 1991) were markedly abundant in 1990. The opposite seemed to be true for Clossiana freija, Oeneis jutta, and Carterocephalus palaemon. No evidence of alternate year flight was found for the more abundant Oeneis species, ©. taygete and ©. melissa (cf. Scott, 1981 ; 1986). The data from Schefferville, central Québec-Labrador peninsula (ANTHONY, 1969 ; KOPONEN, 1980) support the even-year flying pattern of Hesperia comma and Pyrgus centaureae there as well. Clossiana polaris seems to be more common in even years on the Hudson Bay coast (GAUTHIER & KOPONEN, 1987 ; NERON, 1990) and near Schefferville (ANTHONY, 1969 ; KOPONEN, 1980). Due to this flying pattern, a study of butterflies in the north during one summer only may give greatly biased results. 2. Eastern coast of James Bay - Hudson Bay RioTTE (1971) reported 37 species from the closely comparable areas of northern Ontario : Missisicabi River - Fort Albany on James Bay and Cape 70 Henriette Maria - Fort Severn on Hudson Bay (51° 15’-53°N ; Fig. 1). Twenty- five of these were found on the eastern coast of James Bay - Hudson Bay, between Rupert River and Lake Minto (Soerensen’s quotient of similarity ; see e.g. MAGGURRAN, 1988, QS = 0.64). KLASSEN et al. (1989) reported 45 species from northernmost Manitoba; 33 of the 41 species on the eastern coast of James Bay - Hudson Bay were also mentioned for northern Manitoba (QS = 0.77). Morris (1980) listed 37 species of butterflies and skippers found on the Labrador coast, of these 31 were common with the present study area (QS = 0.79). The proportion of circumpolar, Holarctic species increases with the latitude. The percentage of Holarctic species at James Bay sites is 53%, at Kuujjuarapik 74% and at more northern sites on Hudson Bay (Richmond Gulf - Lake Minto) 89%. Of the present total material, between Rupert River and the Ungava peninsula, the percentage of Holarctic species is about 60%. The proportion of Holarctic species in the total Québec butterfly and skipper fauna is only 26% (LAPLANTE, 1985). On the island of Newfoundland this proportion is 46% and on the Labrador coast as high as 67% (Morris, 1980). Around Churchill, northern Manitoba on the western coast of Hudson Bay, the percentage of Holarctic species is about 57% (KLASSEN et al., 1989). The known northern limit of many species approaches the southern end of James Bay (Scott, 1986) and thus several species not mentioned in the present paper probably also occur in the southern James Bay area. Two northern butterflies, Colias hecla Lefebvre, 1836 and C. palaeno (Linnaeus, 1761), known from the Ungava peninsula (LAPLANTE, 1985 ; Scott, 1986), possibly occur in the northernmost parts of the present study area.

Supplement No. 5 : 73-78 ; 31.X.1994 ISSN 0342-7536 Inferences about the function of genitalia in the genus Eupithecia, with description of a new organ (Lepidoptera, Geometridae) Kauri MIKKOLA The Finnish Museum of Natural History, P.O. Box 17, FIN-00014 University of Helsinki, Finland Summary In the geometrid genus Eupithecia, the females usually have a sclerotized half- ring in the ductus bursae, called the colliculum. Bozre (1990) observed that this structure is lacking in the North American FE. palpata group. In this group, the males have the 8th sternite (ventral plate) composed of two long rods and a connecting ridge. It is shown that the rods are basally articulated, and seemingly, they have a forceps-like function. In the 7th segment of the female, corresponding paired pouches for reception of the forceps’ tips were found. These are named “Bolte’s pockets” (crumillae boltei). A hypothesis about the interplay between the male ventral plate and the female colliculum is presented : the mainly species-specific plate is an “opener” of the colliculum, a “key”. It is suggested that in Eupithecia, the recognition function between sexes during the early phase of copulation has shifted from the valvae to these structures. The function of the valvae is probably restricted to a stereo- typic grasping at the beginning of the pairing. The later fixing, recognition and isolating functions are performed by the internal lock-and-key mechanisms formed by the aedeagus and vesica of the male and bursa copulatrix of the female, in a way similar to that published for the noctuid genus Apamea. It has recently been shown that the internal genitalia of noctuid moths function as complicated lock-and-key mechanisms (LAFONTAINE & MIKKOLA, 1987 ; MikkoLA, 1992). In the geometrid genus Eupithecia Curtis, 1825, the male vesica and the female bursa show similar structural correspondences (MIKKOLA, 1993). According to PETERSEN (1909), also in these moths, the male must deposit the spermatophore into the female bursa and appendix bursae so that its opening is against the opening of the ductus seminalis. Otherwise, the sperm transfer in the female cannot take place. Such a deposition succeeds only if the genitalia have the same specific characteristics. Thus, the internal genitalia act as isolation mechanisms. 73 Even though the genitalia of Eupithecia are shown in numerous standard works, very little is known about their function. PETERSEN (1909) is virtually the only researcher who has paid attention to the interplay of the male and female genitalia. He reached the pioneering and important concept, referred to above, that the male spermatophore must corrrespond in shape to the shape of the female bursa. PETERSEN (1909) never made comments about the significance of the female colliculum, a structure peculiar to the genus Eupithecia. This is a dorsal, half- ring-formed sclerotization in the posterior part of the ductus bursae : ventrally the ductus wall is membranous (Fig. 3). Another structure which is typical of the genus Eupithecia is the male “ventral plate”, the modified 8th sternite. Its shape is more or less species-specific, and therefore, most standard works show it for all species, even though the function of the organ was unknown. Bo te (1990) noted that the female colliculum is lacking in the North American E. palpata group, and that the ventral plate in the males of these species is composed of two long rods, fork-like. This cue inspired me to try to figure out what the relation of the ventral plate and the colliculum is; the first results are published in this paper. A review of the lock-and-key mechanisms will be published in a separate paper in cooperation with Mr. Klaus Bolte. Material and methods For this study, genitalia slides made by Klaus Bolte (see Botte, 1990) from the Canadian National Collection, Ottawa, were used. The slides contain both the routine parts and the male vesica everted as well as the male and female abdominal skins. Most slides are stained with chlorazol black, giving a clear separation between membranous and sclerotized parts. The drawings were made using a mirror, so they correspond to the original slides. Results According to McDuNNouGH (1949) the E. palpata group contains 22 species in North America. As Botte (1990) reported, the male ventral plate in the E. palpata group is fork-like with two more or less thin rods and with a narrow transversal ridge connecting the rods basally (Figs 1,2). In most species, like E. longipalpata Packard, 1876 (Fig. 1), the tips of the rods are dorso- ventrally flattened, and spatulate. The rods are usually asymmetric (noted also by McDunnoucH, 1949), the left one being straighter and extending further. The stoutness and length of the rods show specific variation. In E. miserulata (Grote, 1863), the plate is strongly modified (Fig. 2). The rods are strong and flat, and the tips are bent inward; they are strongly asymmetric, the left one being much larger. In addition to what Botte (1990) described, the connecting ridge is not contiguous, but there is a longitudinal crack between the lateral parts, seemingly an articulation surface, suggesting that the ventral plate could 74 1.

This observation led me to search the female genitalia for the grasping points of the tips of the forceps. What was found was a pair of specialized pockets, laterally in the 7th sternite of the female skin. They are usually asymmetric (but because they are soft structures this cannot always be observed) corresponding to the male ventral plate, 1.e. with the right pocket larger. The structure is described here and named Bolte’s pockets (crumillae boltei) in honour of Klaus Bolte who published the outstanding monograph of the Canadian Eupithecia species (BoLTE, 1990), and who observed the connection between the structure of the ventral plate and the absence/ presence of a colliculum. ip DESCRIPTION : Paired depressions of cuticula of female 7th sternite, antero- medial of the stigmata, near 6th/7th intersegmental membrane. Right pocket usually larger than left. Bottom of pocket scaleless, seemingly covered by sensory hairs, in E. miserulata bottom of pocket partly sclerotized. In fresh specimens the pockets are covered by scales of the surrounding skin. Size of pockets varies according to size of tips of ventral plate of male. Altered shape and enlarged size is found in E. miserulata. Discussion In the functional anatomy of the genitalia of species of Eupithecia (Geo- metridae) and those of the genus Apamea (Noctuidae) (cf. MıkkoLA 1993), the following basic differences can be observed : 1. The valvae of Eupithecia are soft and stereotypic, usually without specific characteristics. Those of Apamea are strongly sclerotized and, although they are basically quite uniform, they usually have clear specific characteristics. 2. The 8th sternite of male Eupithecia is a specialized, mostly species-specific structure, while the corresponding sternite in Apamea has an X-shaped sclerotization, similar in all species. 3. In most species of Eupithecia, except those of the E. palpata group, there is a colliculum, which is not known in the genus Apamea. There seems to be no doubt that the ventral plate in the Æ. palpata group acts as a tool grasping the female in her Bolte’s pockets during the early phase of copulation. In Fig. 3, a hypothesis is presented to demonstrate how the ventral plate may interact with the colliculum. The colliculum in the female’s ductus bursae is a double half-ring with the dorsal side rigidly sclerotized and the ventral side membranous, laying tightly a. Before b. Opened by c.

When Zupithecia bursae are inflated by injection, this point is particularly difficult to pass with a syringe needle (K. Bolte, pers. comm.) which is the same as what the male is doing with its aedeagus during copulation. The male ventral plate 1s usually more or less wedge-shaped. I have found some evidence concerning corresponding measurements and shapes of the ventral plate and the colliculum. Therefore, I propose that the ventral plate is a tool for the opening of the colliculum. In the early phase of copulation, it would slide ventrally of the ductus bursae, widen the distance between the lateral walls of the colliculum and thus open the ductus bursae. Once the aedeagus has gained entry to the ductus, the colliculum structure is no longer apparent. Therefore, its function must be restricted to the early phase of the copulation. How exactly the interplay between the ventral plate and colliculum occurs, remains to be demonstrated. The former is contiguous with the abdominal scale-covered skin, and the latter is situated under the skin. It may be that the end of the abdomen is telescopic in both sexes. The colliculum of the female may well come out from the abdominal skin to be covered only by a thin inter-segmental skin. The dorsal surface of the ventral plate probably slides into the colliculum, which would require a telescopic abdomen from the male. This problem can only be solved by following and perhaps filming the early phase of the copulation. Because the colliculum is needed only in the early phase of the copulation, the process being loosely species-specific, I propose that the valvae in the genus Eupithecia have lost parts of their function to the ventral plate/colliculum combination. Their function is most probably restricted to grasping the female in the first phase of copulation. In the genus Apamea, the valvae would have both grasping and recognition functions ; they have retained the “loosely species-specific” function. The significance of the valvae and ventral plate would be at the end, when the male has inserted the aedeagus and vesica into the ductus bursae and bursa copulatrix of the female. Thereafter, the latter structures are undertaking the fixing and sperm-transferring, and, in the case of non-conspecific copulations, isolating functions (LAFONTAINE & MIKKOLA, 1987 ; MIKKOLA, 1992).

El Mirador, Marbella, Spain Summary Many species of the genus Elachista present difficult identification problems. The venation is proposed as a simple identification aid within species com- plexes. Examples are presented from the recently published revision of the E. dispunctella complex, which comprises 54 species. When The Elachistidae (Lepidoptera) of Fennoscandia and Denmark (TRAU- GOTT-OLSEN & NIELSEN, 1977) was published, it was the first work to fully treat the northern European species of this family and as such satisfied the urgent demand for a guide to their identification. Since then, however, addi- tional species have been described, several mistakes have been corrected and further revisions have been published. SVENSSON (1966) published a paper on the separation of Elachista triseriatella Stainton, 1854 and Elachista dispunctella (Duponchel, 1843). As Elachista dispunctella, he considered specimens having genitalia with a long and slender aedeagus without cornuti; this turned out to be a lucky choice. Svensson also mentioned that the type of Elachista dispunctella Duponchel in the Paris Museum was without abdomen, and thus he could not be certain about the genitalia. In 1986, on my way to the V. SEL Congress in Budapest, I paid a visit to the late Dr. Kasy in Vienna. He generously put the museum collection of Elachista “dispunctella” Dup. at my disposal and gave me a free hand to study all specimens, including making venation preparations if necessary. I had already found the study of venation valuable in the 1977 work. On my way back to Spain from Budapest, passing through France I took the opportunity to visit the museum in Paris and due to the kindness of Dr. G. Luquet I was allowed to borrow the type of Elachista dispunctella Dup. This specimen had both forewings, but only one hindwing, and so I was able to make a venation preparation of one of the forewings. 19 I have since been able to study a large material of this species complex, and based largely on the venation, colour of the undersides of the wings (Dupon- chel stated that the undersides of the wings of dispunctella were white), and the male and female genitalia, a remarkably large number of new species (44) has been detected. It was found that males and females have an equal or almost equal venation and that the venation was to a high degree species specific within the complex. The results of this study have now been published in detail, including venation, male and female genitalia and colour figures of the upper and undersides of the wings (TRAUGOTT-OLSEN, 1992). The reader is referred to this paper for the characterisation of the complex. The species could be conveniently split into 8 groups or sections, based on the venation at the apex of the cell. All of the known species are listed in Table 1, according to section, giving the countries from which they have been reported and the number of specimens examined. The venation characterising the sections are illustrated and defined in Figs 1-8. The method used for visualising the venation is given in TRAUGOTT-OLSEN & NIELSEN (1977 : 34).

In addition, the venation of all specimens was identical to that of the holotype. These specimens are therefore considered to be dispunctella. The male described and figured under that name in TRAU- GOTT-OLSEN & NIELSEN (1977, Figs 94, 201, 338, 339) is the recently described E. multipunctella Tr.-O., whereas the female (loc. cit., Figs 95, 463) was proven to be E. pollutella (Dup.)

However, E. mannella belongs to section I, whereas E. dispunctella and E. dalmatiensis belong to section II. E. dispunctella has R2 arising well before the origin of CuA2, whereas E. dalmatiensis has R2 arising above the origin of CuA2. Additional differences between these three species can be found in details of the genitalia: Vinculum, juxta lobe, digitate process, anellus and aedeagus (Fig. 9). To further illustrate the species specific venation, the venation, vinculum and uncus of four species belonging to section IV are compared in Fig. 10. E. intrigella has R2 arising well before the base of CuA2, while in E. karsholti R2 arises beyond the base of CuA2, paralleling the specific differences in the vinculum. The size of the anellus sac, wing pattern and antennal characters also distinguish the species (TRAUGOTT-OLSEN, 1992). In E. baldizzonella, the saccus is rather pointed, while that of E. tribertiella is rounded. In E. bal- dizzonella the distance between the base of R3 and the apex of the cell is much longer than in E. tribertiella. R2 arises well before or well after the base of CuA2 in E. baldizzonella and E. tribertiella respectively. With these characters, it should be easy to distinguish these species. An additional character is seen in the uncus lobes, which are narrowly incised in E. bal- dizzonella and broadly incised in E. tribertiella. Discussion Colleagues have often been confused when I have tried to explain my points of view on the value of the venation in species identification. I will try to clarify a few points. 1. The results presented here concern only the Elachista dispunctella complex. Similar and parallel situations have been found in the Elachista triseriatella and Elachista dispilella complexes. 2. A complex is first established by the common characters of the genitalia in both sexes and not necessarily including the study of the venation. In two different complexes I have found equality in the specific venation, demon- strating that the venation alone cannot be used to identify a species without knowing to which complex it belongs. The genitalia remain the single most important character to separate species and species complexes, although other factors such as wing markings biology must also be taken into account. The venation is only a separating character for the species within the complex and can be used to group the species. 3. Any description of a new elachistid species will have to state the complex to which the new species belongs, with diagnoses and discussion of all the species of the complex and full descriptions of the adults, including genitalia and venation. 4. Venation is only a secondary character emphasising the polyphyletic nature of the genus Elachista. To arrive at a proper division of this conglomerate 84 Elachista mannella Tr.-O.

It is not suggested that the evolutionary relationships between species within a complex can be determined from their venation, rather that the intra-specific variation is rather small and the inter-specific variation rather large, thereby allowing this character to be used in combination with other characters as an aid to identification. It has also helped to refer previously unknown female specimens to their male counterparts, and vice versa. An advantage of using the venation as an identification aid is that preparations are less likely to suffer the distortions often found in genitalia preparations, thereby avoiding errors of interpretation.

DaArLr'Asta Musée Royal de l’Afrique centrale, B-3080 Tervuren, Belgium. Summary A revision of the genus Eudasychira Möschler was undertaken in 1983. At that time it was noted that the male genitalia offer many good diagnostic features at the species level. The evolutionary significance of the complex structure of the male genitalia has now been investigated. The studied characters have been interactively analysed with the HENNIG program. The resulting 17 trees showed that there were not too many discrepancies between the characters, but a well-marked infrageneric classification could not be proposed. The problems in the nomenclature of the different parts of the male genitalia are explained and a few data concerning the distribution of the species is also mentioned. The male genitalia of the taxa recognized as belonging to the genus Euda- sychira are very complex (DALL'ASTA, 1983). Thorough examination showed that these genitalia possess a unique feature within the Lymantriidae: a peculiar form and position of the saccus. Instead of being a tubular structure extending midventrally below the valvae, the saccus extends above the valvae. This is most easily seen in E. quinquepunctata (Fig. 1), the type species of the genus, where the valvae join ventrally and their ventral edges bend dorsally back cephalad forming the subrectangular saccus on which the penis can slide. Describing this character in another way, it can be said that the attachment point of the valvae to the saccus is situated below instead of above, and that consequently the saccus is suspended between these valvae. This peculiar feature of the saccus transforms quite a few other parts of the genitalia and the transformations of the valvae themselves are the most striking. Instead of being flattened sacs, they are semi-circularly bent in order to leave space medially for the saccus. This peculiar form of saccus and valvae can be considered a unique apomorphic character to distinguish taxa belonging to the genus Eudasychira from all other Lymantriidae. Examining all preparations of Lymantriidae available proved that this genus only occurs in the Afrotropical region. In some species the saccus situated 89 SR Wege | en VS aos Deno OR Re PS QE ES) Sosa.harpre Fig. 1.

Scale : | mm. above the ventral portion of the valvae can be rather small ; the valvae are then attached to its lateral edges and remain flattened. Including the species with these flattened valvae, a total of 33 species can now be recognized in the genus Eudasychira. The unique forms of saccus and valvae are not the only peculiarities of the genus. The male genitalia of the taxa of the genus Eudasychira possess at least three other distinct structures not present in any other Lymantriidae, and for which no nomenclature exists in the literature on the morphology 90 of male genitalia of Lepidoptera in general. One of these are the two hairy processes within the saccus (Fig. 1, sa.ha.pro). These hairy processess occur also in other species where they are situated on the edge of the rim saccus- valvae ; in this case these hairy processes are protruding outside the genitalia instead of being situated within the saccus. In some species, more sclerotized processess can occur in the same place as where the hairy processess of E. quinquepunctata are situated. Due to the fact that they are more sclerotized, never hairy and always situated at the same position, they cannot be consi- dered homologous to the hairy processes, which are always elongate. These sclerotized processes on the other hand can display quite different forms (characteristic for the species) and can even transform into paired hooks protruding outside the genitalia from within the saccus. These two kinds of processes occur only in species with circularly bent valvae, as in E. quin- quepunctata. In some species with flattened valvae on the other hand (and also in a species with forceps-like valvae) a long ventral ribbon (having at least the length of half of the genitalia) can be attached to the distal portion of the saccus. This ribbon can be simple or divided and is also a character unique within the Lymantrudae. Apart from these characters, some species of Eudasychira display other peculiar structures characteristic of a limited number of its species. Some of these characters can only be considered transformations of parts of the valvae or other ‘recognisable’ parts of ‘classic’ types of genitalia (uncus, vinculum, etc.). But it should be borne in mind that the male genitalia of species of Eudasychira can be of very different forms and that sometimes single species can display some peculiar processes or forms of valvae unique within the Lymantriidae. The above findings once again raise the question of the use of a “nomenclature of convenience” for naming the different parts of the genitalia in Lepidoptera (Kiots, 1970 : 116). If distinct names have to be given to all new structures of the genitalia, in the genus Eudasychira alone this would mean the intro- duction of at least three new names. Therefore, together with the pertinent remarks of SIBATANI (1972) on Klots’ paper the nomenclature and glossaries of terms to be used in describing male genitalia of Lepidoptera should be considered established by those two papers. One should avoid proposing new names as WELLER (1990) has done for a group of nystaleine Notodontidae. To gain some insight into the evolutionary trends of the different characters within the species, all characters of all species have been coded and this data analysed with the HENNIG 86 program. The resulting 17 trees showed that there were not too many discrepancies between the characters, but a well- marked infrageneric classification could not be proposed. Many of the taxa were isolated, or in pairs, sister groups of the rest of the tree (a kind of chaining), but in all trees the species with flattened valvae are situated near the root of the tree and the species group with the large saccus and the bent valvae always clusters at the end. This could show a trend, i.e. saccus becoming larger when more apomorphic characters are present, which was also sub- jectively felt at the moment of coding. Hi References DaALL'ASTA, U. 1983.

Resume Les relations phylétiques entre les espèces ouest-européennes du groupe de Erebia tyndarus ont été étudiées au moyen de l’analyse électrophorétique des enzymes. Deux groupes de populations génétiquement distinctes ont été déce- lées au sein d’E. cassioides s.l., l’une vivant dans les Alpes orientales (E. cas- sioides s.str.) et l’autre comprenant les populations des Alpes occidentales, des Apennins italiens et des Pyrénées (E.

Dans l’intérêt de la stabilité de la nomenclature, un néotype de Papilio cassiodes Reiner & Hohenwarth, 1792 a été désigné. 93 Introduction WARREN (1936) originally classified the Erebia tyndarus species complex within a broader E. pluto group. It was considered to include E. tyndarus (Esper, 1781), E. ottomana Herrich-Schäffer, 1847 and E. callias Edwards, 1871, each subdivided into many subspecies. A number of later authors contributed to raising to species rank one or another of these subspecies, whereas meanwhile a few totally new species have been described. Currently, also E. cassioides (Reiner & Hohenwarth, 1792), E. hispania Butler, 1868, E. iranica Grum- Grshimailo, 1895, E. dromulus Staudinger, 1901, E. calcarius Lorkovic, 1953 and E. nivalis Lorkovié & de Lesse, 1954 are considered distinct species by most authors, so bringing the total of members of the E. tyndarus group to nine. As male and female genitalia are very similar throughout the group (DE LESSE, 1960) and as a consequence of the fact that these species are rarely found in cohabitation, NicuLEscu (1985) reverted to the original suggestion of Warren that they should all be considered separate subspecies within a polytypic complex. In at least one case, however, cohabitation does occur : E. (iranica) transcaucasica and E. ottomana are known to fly together in E. Turkey. Members of the E. tyndarus group are characterized by their small size, rounded wing shape, the presence of a normally reduced orange-brown stripe on the apical third of the wings, surrounding a pair of small black spots, pupillated white. The hind wings are normally ash-grey on the ventral surface, often with a yellowish tinge in the females. Males lack androconial scales. In the male genitalia, the valva shows a series of upwards and rearwards directed spines, the most proximal of which is normally the largest. The rear half of the valva itself recalls that of E. pluto (Warren, 1936), as it tapers caudad rather smoothly, without any real interruption between what this author called a ‘shoulder’, a ‘neck’ and a ‘head’. Caterpillars appear finely pubescent due to the presence of many short setae. All taxa of this group are alpine or subalpine, perhaps with the exception of E. ottomana, which can often colonize the upper parts of the montane vegetational level. All are Palaearctic, but the range of E. callias extends to the Nearctic. The karyological study of this group, carried out by Lorkovié (1941) and DE LESSE (1960), demonstrated that haploid chromosome complements vary between species. E. tyndarus and E. cassioides have n = 10; E. calcarius n= 8; E. nivalis n = 11; E. callias n = 15; E. hispania hispania n = 25 ; E. hispania rondoui n = 24; E. ottomana n = 40; E. iranica iranica and E. iranica savalanica n = 51 ; E. (iranica) transcaucasica n = 52, E. dromulus n= 51 or 52. WARREN (1955, 1981) taking again in consideration the taxonomy of this group, came to rather different conclusions. This author, in fact, doubted that E. cassioides, first described from the Großglockner (Austria), really inhabits this region. As a consequence of the fact that Reiner & Hohenwarths’ figure, later designated as lectotype of E. cassioides (LORKOVIC & DE LESSE, 94 1955) cannot be identified with any known species, he considered E. cassioides a nomen nudum, perhaps to be identified with E. nivalis, a species also described from the Großglockner. He also split what was formerly known as E. cassioides into two species, namely EF. neleus (Freyer, 1833) and E. aquitania Fruhstorfer, 1909, on the basis of some subtle morphological characters of the wing shape (more pointed in E. neleus). Among more recent authors, however, only von MENTZER (1960) followed this suggestion ; most other authors (DE LESSE, 1956 ; Hiccins, 1975, etc.) maintained E. cassioides as a valid and single species. The present work deals with the West European members of the Erebia tyndarus species group and aims at the clarification of some of the taxonomic problems outlined above, by the study of electromorph variation. Only E. cassioides arvernensis Oberthir, 1908, from the Mont Dore (Auvergne, France) and E. cassioides dolomitensis Goltz, 1930 from the Italian Dolomites and Caravanche Alps remain, for the moment, unstudied. Materials and methods Preparation of samples Twenty-four populations of the E. tyndarus species group were scored for electromorph variability, for a total 290 specimens. Collection data for each of these populations are listed in Tab. 1, where, as regards western populations of E. cassioides, WARREN’S (1955, 1981) suggestion that E. neleus and E. aquitania may represent separate species was followed, for the sake of clarity. One population of E. gorge from Colle del Dragone (Province of Potenza, S.Italy) was included as an outgroup. The wings were immediately removed on collection with sharp scissors and the whole bodies were frozen in liquid nitrogen while still alive. The specimens were stored in the same medium. Samples were prepared for electrophoresis as follows. Individual butterfly bodies were thawed in 250 pl of an ice-cold homogenizing solution (NADP 0.125 mM, 2-mercaptoethanol 1.14 mM ; pH range between 6-8) and macerated with an electric tissue grinder. Centrifugation at 13,000 x g for 15 minutes permitted the separation of a clear supernatant. Care was taken to avoid overheating during both homogenization and centri- fugation. Homogenates were stored at -80°C in 5-15 ul aliquots in microtubes. Electrophoresis Electrophoresis was carried out on Cellogel sheets at 4°C. Buffer systems and staining techniques were similar to those described by MEERA KHAN (1971) and RicHARDSON ef al. (1986). Thirteen gene-enzyme systems were studied for a total of 17 loci. Genetically interpretable banding patterns could be obtained for : glycerol-3-phosphate dehydrogenase (E.C.1.1.1.8) (aGPD), malate dehydrogenases (E.C.1.1.1.37) (MDh-1, 2), isocitrate dehydrogenases (E.C.1.1.1.42) (IDh-1, 2), 6-phosphogluconate dehydrogenase (E.C.1.1.1.44) (6PGD), glucose-6-phosphate dehydrogenase (E.C.1.1.1.49) (G6PD), glutam- 95 (234103) OD (snoJ2U) LN (snajau) 9N (snajaul) SN (snajau) YN (snajau) EN (piupnnbo) pV (piupunbp) Ev (SNLIDIIDI) 89) (Sisua2DUAG PUDWONO) TO (sıjpaau) IN (sapıoıssp2) SI (saploisspa) po) (S2P101S$D2) ED (sopıoıssp>) 79 (S2p1018$D2) 19 (sninpudi) AL (piuviinbp) TV (pıupunbo) |v (PJOU2p1D1 puDwono) [JO (pdo3 ‘J ınopuo4 vıupdsu/) £H (snajau) TN (1nopuo4 pıupdsıy) TH (snajau) IN (piupdsiy mıupdsıy) 1H eıueanT? ‘ourjod ‘AJ eıueonT ‘OUIIO4 ‘ATP ızznıqy ‘osezzniqy ouruuoddw ‘Aje1] IZZn1qVY ‘os9ZzZn1qy outuusddy ‘Afeyj IZZNIQGV ‘osazznıqy ouruusddy ‘Are AUDIPIN ouersiyssepy ouruusddv ‘Afey] BIW ‘ouerwg-o9so] ouruusddy ‘Ayet] PIN ‘oueiwfg-o2so] outuuoddw ‘Aeyf AU ‘ouyoruie Idesıqg ‘Afe] ounusı] ‘uw opfeg ‘API emule) ‘UNE ], AUCH ‘CHISNY enunIe) ‘Une ] 9yoH "eLNsnV ounusı] ‘oyonoy ıdıv ‘Ayer ounusı] ‘syonoy Idıv ‘Aye ounusı] ‘oysnoy ıdıv ‘ATAII ounusı] ‘ayonoy !dıv “Are BJSOV.P [eA 'sdjv ouruusq ‘Aye I] BISOV,P JPA ‘Sdiv uere19 ‘ATeI] Juowpaıg ‘Sdiv ue109 ‘Aye AU99P1V ‘SIBIBAIA ‘IN SOUBI ‘10 ‘IAd ‘sooudtAg ‘surly sooudlAd ‘eilopuy toSonH ‘soousiAg “ureds Bliqejue, ‘sui IN URLIgejURD ‘ureds epeueln PPEAIN BIIAIS ‘ureds uorsay “Anunoy uodelg [pp 209 uogelg [OP 209 ejpofe e119S EI OdeD [eA OSH) OW ousleg [op ITA AUOT) ‘MN BU9IEPEI IP 0S4 offeae) “WW OSEN IP OWISSHTY NA 10}YIOH [EZ NZ QUOIQUIBN [PA 00€7 u ‘azzog div 0007 W ‘52204 diy 0081 u ‘azzoq div opıeulog 'S ULIO OS AUdA [eA opsusy.[op AD onsieuel 97 nosiuey JuoW BIeCAUY 9P 01d OJ991P1N op “Quy OTIO[O) UBS 9P 017g SBUIQRS SET 9P TIOD AYfR90T U9IIAA 0) SUIPIO0998 PAIJISSEIO 918 sopıoıssp> ‘ Jo suoremndod uiasom ‘pardues dno13 snuppud) viga«q sy) Jo suonendoq I STQUT 96 ate-oxaloacetate transaminases (E.C.2.6.1.1) (GOT-1, 2), glutamate-pyruvate transaminase (E.C.2.6.1.2) (GPT), hexokinase (E.C.2.7.1.1) (HK), pyruvate kinases (E.C.2.7.1.40) (PK-1, 2), phosphoglucomutase (E.C.2.7.5.1) (PGM), mannosephosphate isomerase (E.C.5.3.1.8) (MPI), phosphoglucose isomerase (E.C.5.3.1.9) (PGI), esterase (E.C.3.1.1.1) (Es). Isozymes and alleles were de- signed numerically according to their decreasing mobility rate. Statistical analyses Several genetic distance indexes were calculated (Cavalli-Sforza and Edward arc and chord distances, 1967; Rogers D, 1972; Wright’s modification of Rogers D, 1978 ; Nei’s D, 1972 ; Hillis modification of Nei’S D, 1984). Dendro- grams using UPGMA method of SOKAL & SNEATH (1963) and FitcH & MARGoLIAsH method (1967) were constructed from these distances. A phylo- genetic tree connecting all populations studied was obtained by the “Continuous Characters Maximum Likelihood Method” (CONTML ; FELSENSTEIN, 1981, 1985). This program assumes that each locus evolves by genetic drift, so that gene frequencies may be considered to behave like particles undergoing pure Brownian-motion. Results Allele frequencies are shown in Table 2. The overall number of alleles detected at 17 loci of all Erebia tyndarus species group studied amounts to 64 (mean per locus 3.76, range 2-8). No locus proved monomorphic across the whole sample. An additional private allele (HK 110) was identified in E. gorge. The allele GOT-1 90 was found in the three populations of E. hispania only ; the allele GOT-1 110 is diagnostic for E. nivalis, PK-1 115 for E. ottomana. Studied populations of E. tyndarus, E. neleus (7), E. aquitania (4). E. cassioides (5), and E. calcarius (1) did not show any private allele. All dendrograms obtained by the various distance and clustering methods outlined above concur to a single picture : 1. E. gorge (outgroup), as expected, proved to be the most genetically different taxon (D = 0.719). The E. tyndarus group, accordingly, may represent a monophyletic unit. Its first split occurs at Nei’s D = 0.407. 2. Populations of E. cassioides (E. neleus + E. aquitania) from the Italian Apennines, the western Alps, the Pyrenees, the Cantabrian Mountains (western populations of E. cassioides, 11 populations) cluster together at much lower values (Nei’s D = 0.015). 3. Populations of E. cassioides from the central-eastern Alps (eastern E. cassioides, 5 populations studied) also cluster together at low distance (Nei’s D = 0.016). 4. Eastern and western E. cassioides, in contrast, cluster with each other at a considerably higher level of distance (Nei’s D = 0.071). 97 OOT 001 0€°0 0L 0 001 SO 0 S00 r00 ct O ÿ0'0 960 O0T 00°I 490 O0T 00°I 960 00 ‘T $60 960 760 00 I 2460 007 r0'0 ÿ0 0 ÿ0'0 £00 001 960 00°I ODOT OOT OOT OOT OOT OOT ODOT OOT ODOT OOT OOT ODOT OOT OOT OOT OOT OOT ODOT ODOT ODOT OOT ODT r0°0 » Sc et NEO. oa Er OS A AN NENNEN Py Gey cy N g[qissod jou sem Suroos uonendod ayJ ur je} SoxeOIpUT .-, 'P21095 319M suonerndod [fe Jo spenprArpur [fe jou awÂZzus autos JO] ‘I Qe ur se paroqunu ae suonendog 'suonepndod ¢z ut 190] Jıydıowouow-uou pareus /] Ye sawuanbaıg 921 c SIgeL ae Où DA IN oo AL DD DO DD GN IN UN ON TEN WN EN Ar ANA 7 Nei genetic distance 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0.05 0.0 | | | | | | | | | N5 A4 A1 N2 Nı Na N4 A2 N7 N6 A3 C1 C 2 C4 C5 C3 Ca Ty O1 02 Ni Hı te Su H3 Go Figure 1.

E. cassioides (E. neleus + E. aquitania), E. tyndarus and E. calcarius also cluster at similar levels (Nei’s D [E. cassioides - E. calcarius | = 0.096 ; [(E. cassioides + E. calcarius) - E. tyndarus | = 0.147). 6. E. nivalis is the most genetically distant species of the Æ. tyndarus-E. cassioides-E. calcarius lineage (Nei’s D ~ 0.3). 7. The two populations of E. ottomana are genetically rather distant (Nei’s D = 0.177). 8. Among populations of E. hispania the closest are ‘ssp. rondoui’ and ‘ssp. goya’ (Nei’s D = 0.063), whereas the nominotypical form is genetically quite distinct (Nei’s D = 0.155). The UPGMA cluster of Nei’s genetic distances is shown in Fig. 1. The ‘phylogenetic’ tree obtained by the Continuous Characters Maximum Likelihood Method, is shown in Fig. 2 and concurs with the tree shown in Fig. 1 in all its most important aspects. Discussion All our results suggest that the distinction of E. neleus and E. aquitania 1s untenable and that this complex is well distinct from E. nivalis. The two populations collected at different altitudes on Großglockner, which we identi- fied as E. cassioides (low altitude) and E. nivalis (high altitude) on characters of wing morphology, show a genetic distance of D = 0.358. Accordingly, and apart from other nomenclatural problems (see below) they can be identified as topotypic samples of their respective species. It remains to be stressed that FE. cassioides sensu lato is a complex of two genetically different groups of populations. One, including the type locality of E. cassioides, occurring at least in the Rhetian Alps and the Tauern. The other includes all populations from the Italian Apennines, the central and western Alps, the Pyrenees and the Cantabrian Mountains. The names by which these groups of populations can be identified will be dealt with further on. The relatively small genetic distance between these two taxa (Nei’s D = 0.071) is probably a consequence of them having become separated in recent times. On the basis on Nei’s calibration of the molecular clock these two taxa would have started to evolve independently about 0.35 Myr ago. Since this date gene flow was presumably interrupted by the intervening populations of E. tyndarus, a species already genetically distinct from the rest, having the fixed allele MPI 70 (absent from all populations of E. cassioides s.1. and otherwise only found in E. hispania) and lacking the allele PGI 100 (very common in E. cassioides s.l.). The interruption of gene flow between eastern and western populations of E. cassioides s.l. is demonstrated by the absence of allele 6PGD 100 from populations of the former. Subsequently, the rising temperature may have progressively confined western populations of E. cassioides to the moun- tain peaks of the Alps, Apennines, Pyrenees and Cantabrian Mountains. Nei’s distances between these populations generally vary between 0.01 and 0.02, 101 which would place such events in the interval of 50,000 - 100,000 years bp. These distances, however, are too small to be reliable and should be confirmed by independent studies on mitochondrial DNA. On purely morphological grounds populations of the ‘western group’ are not easily identified from nominotypical Erebia cassioides. The latter generally have slightly smaller size, more rounded wings at apex and are darker grey on ventral surface of the hindwings, with a normally less neatly black edged discal stripe. In females the hindwing colouration is silvery grey on ventral surface, with almost no hint of a yellowish or creamy wash. The opposite applies to populations of the ‘western group’. A potentially interesting field for future research would be to investigate genetic distances between other ‘subspecies’ having similar distributions, such as those found within E. pronoe, E. meolans, etc. It may be worth noting that the presence of another species occurring between populations of an eastern and a western group may have contributed to an earlier interruption of the gene flow, as well as to keep the interruption in place by mutual exclusion, when more favourable environmental conditions took over. Where such a situation is lacking, e.g. for E. euryale, E. pluto, E. gorge, etc., there is enough morpho- logical evidence to suggest that hybrid populations exist in between, where they probably represent the outcome of secondary hybridization events. Another lineage is that of E. hispania, where even though no cohabitation can obviously occur between populations of the Pyrenees (N Spain) and Sierra Nevada (S Spain), genetic distances suggest that two different species are involved : E. hispania (Sierra Nevada) and E. rondoui (Pyrenees). Such a distinction is supported also by their different haploid chromosome comple- ments (n = 25 and n = 24, respectively) and external morphology. It is finally worth mentioning that the only two western European populations of E. ottomana, the so called ‘ssp. tardenota’ and ‘ssp. benacensis’, sharply differ from each other on a genetic, as well as on a morphological basis. A final word on this subject, however, cannot be spoken until populations from the Balkan peninsula and Turkey have been analyzed. Nomenclature 1. The application of the name Papilio cassioides Reiner & Hohenwarth, 1792. The reasons why WARREN (1981) considered Reiner & Hohenwarths’ name a nomen nudum (i.e. a name that fails to conform to Articles 11-13 of the Inter- national Code of Zoological Nomenclature, ICZN) have been dealt with al- ready. Such a contention, however, finds little support in the current edition of the ICZN, since the publication of this name not only was accompanied by a description, but a specimen (presumably the holotype), now lost, was also figured. Neither can this name be considered a nomen oblitum (1.e. a for- gotten name, a term that has been omitted from recent editions of the ICZN), because it remains by far the most commonly employed name in current 102 literature. On the other hand, however, it is true that although both the description and the accompanying figure are taxonomically obscure, the description may subjectively be presumed to represent the taxon currently referred to as E. nivalis Lorkovié & de Lesse, 1954. To preserve nomenclatural stability, therefore, we think that the most straight- forward nomenclatural option is at this point to select a neotype, in accordance to provisions of Art.75 of the ICZN. Accordingly, we herewith designate the male specimen labeled : Zirknitztal : Großglockner : Austria, 30.07.1991, leg. L. Cassulo, deposited in the collection of the Museo Civico Giacomo Doria (Genoa, Italy) as neotype of Papilio cassioides Reiner & Hohenwarth, 1792. 2. Western and southern populations of the Erebia cassioides complex. The discovery that two genetically different groups of populations can be identified within the E. cassioides complex resurrects WARREN’S (1955, 1981) suggestion, albeit on different grounds, that two different species may have been confused under this name. The name Erebia neleus (Freyer, 1833), how- ever, probably cannot be employed for either of these, as it was proposed to designate some electrophoretically still unstudied populations from the Alps of Transsylvania (Retezat Mts) which may prove conspecific with E. cassioides. Should populations of the ‘western group’ be found to be distinct at species or subspecies level, they should be designated by the name Erebia (cassioides ) carmenta (Erebia tyndarus carmenta Fruhstorfer, 1909 — Soc. ent., 24 : 223 — type locality : N.Italy : Province of Aosta: Alpi Graie : Courmayeur), rather than Erebia (cassioides) aquitania (Erebia tyndarus aquitania Fruhstorfer, 1909 — Soc. ent., 24: 125 — type locality : Maritime Alps). Although both names bear the same author and date, selecting carmenta will have the advantage of avoiding confusion with other treatments of the group. It is rather unfortunate, in this connection, that Reverdin’s name ‘murina’ cannot be employed, as infrasubspecific, and as such invalid on a nomenclatural basis (E. tyndarus var. cassioides forma murina Reverdin, 1909 — Bull. Soc. lépid. Genève, 1 : 292 — type locality : Le Moléson, Prealps of Freiburg’s Gruyère, Switzerland).

BALLETTO** * Istituto di Zoologia, Università di Genova, Via Balbi 5, I-16126 Genova, Italy ** Dipartimento di Biologia Animale, Universita di Torino, Via Accademia Albertina 17, I-10123 Torino, Italy Summary Relationships between monomorphic species of the subgenus Agrodiaetus have been studied by enzyme electrophoresis. Results indicate that all species tradi- tionally recognised on the basis of de Lesse’s karyological studies may represent real species. Irrespective of problems of holocentricity it also appears likely that chromosome rearrangements may have contributed to speciation in this group of insects. Zusammenfassung Die Beziehungen zwischen den monomorphischen Arten des Subgenus Agro- diaetus wurden mit der Hilfe elektrophoretischer Methode untersucht. Die Ergebnisse zeigen, daß die Arten, die gewöhnlich nach de Lesse’s karyologischen Untersuchungen anerkannt werden, echte Arten sind. Trotz des Holocentrismus- problems, haben vermutlich “Chromosomen-Rearrangements” in der Arten- bildung dieser Insektengruppe eine Rolle gespielt. Resume Les relations phylogénétiques entre les espèces monomorphes apartenant au sous-genre Agrodiaetus ont été étudiées au moyen de l’analyse électrophorétique des enzymes. Nos résultats suggèrent que toutes les espèces traditionnellement reconnues dans ce groupe sur la base des études caryologiques conduites par de Lesse, représentent de véritables espèces. Quoi qu’il en soit de l’holocentrisme chromosomique chez les Lépidoptères, il semble aussi très probable que quel- que mécanisme de réarrangement chromosomique puisse avoir contribué à la spéciation au sein de ce groupe d’insectes. 105 Introduction Members of the subgenus Agrodiaetus (Hübner, 1822) are widespread across Europe and Asia, and range from the Iberian peninsula to the Altai Mountains and further to the east, with a distribution characterized by extreme geo- graphical fragmentation. The identification of species of Agrodiaetus can be quite difficult. As a conse- quence, the systematics of this subgenus goes little beyond alfa-taxonomy and no phylogenetic reconstruction has so far been attempted. Morphological features traditionally employed in butterfly taxonomy, either do not sufficiently differ between species (e.g. male genitalia) or, although variable, are not suf- ficiently constant at the intraspecific level (e.g. female genitalia, shape of andro- conial scales, etc.). So far, therefore, most taxonomic work has been based on characters of wing colouration and markings. In this respect, two groups are traditionally re- cognized. One includes the so-called dimorphic species, whose males are promptly identified by their blue wings, on the dorsal surface, as opposed to the brown wings of females. The other group includes monomorphic entities only, with dark brown wings in both sexes. FORSTER (1956), working on this basis, was the first to attempt a broad revision of Agrodiaetus. Since using chromatic characters within the monomorphic forms of the P ripartii complex is impossible, however, his work was almost entirely dedicated to the study of the dimorphic complex. A major problem deriving from the use of characters such as the shade of the blue colour on the dorsal surface of the male’s wings, or the extent and degree of development of submarginal markings on the ventral surface of the hindwings, etc., is that the interpretation of their relative weight may be subjective. Notwithstanding the great importance generally attached to Forster’s work, therefore, it is not surprising that solutions offered by this author for some taxonomic problems remain controversial, while others have been abandoned altogether. The extensive karyological study carried out on members of this and other subgenera of Polyommatus by the late Hubert de Lesse while working in the Paris Natural History Museum from the late 1950s (DE Lesse, 1957; 1959a,b,c,d,e,f ; 1960a,b,c ; 1961a,b ; 1962a,b ; 1963 a,b,c) was immediately welcomed by lycaenid specialists. Characters derived from haploid chromosome complements soon became widely employed in the taxonomy of this group, where they contributed considerable changes. On this basis, many morpho- logically almost indistinguishable forms of the monomorphic complex have been recognized as distinct species, whereas a number of new species have been described both within this and the dimorphic group. Not even this study, however, could provide a definitive solution to the bio- logical riddle of Agrodiaetus. A first problem is that butterfly chromosomes are normally seen in a contracted state, when they do not show any of the 106 karyological details used to identify homologous regions. What is worse, it soon became apparent that Lepidoptera chromosomes may be holocentric, (see WuirE, 1973 for a review). Should this be true, it is contended, haploid chromosome complements (1.e.‘chromosome numbers’) would provide little or no evidence for speciation. Holocentric chromosomes, ın fact, could con- ceivably pair with each other almost at any homologous region, and not at the centromeric region only as is usual. For similar reasons they could freely become fragmented, or bind on ends to each other, etc. without necessarily causing any major karyological imbalance. Even though views on this subject seem now to be changing again (see BIGGER, 1960 ; SUOMALAINEN, 1969 ; or Lorkovié, 1990 for a review), haploid complements permit, at least, various interpretations. For example, whereas different haploid complements, as such, perhaps should not be considered sufficient evidence for speciation, when en- countered in morphologically similar allopatric populations, the discovery of sharp karyotypic differences between parapatric or sympatric populations may represent a strong argument to assume that gene flow has been interrupted. For all these reasons, however, the unusually broad varıability in haploid chromosome complements currently known to exist within the subgenus Agrodiaetus (from n = 7, in Polyommatus nephohiptamenos to n= 125, in P. dolus), combined with the lack of evidence from crossing experiments to determine levels of hybrid dysgenesis, stimulate questions on whether or not the 60 odd currently recognized species may really all represent biologically distinct taxa. The purpose of this work is therefore to i) utilize electrophoretically detectable enzyme variability to analyze levels of genetic divergence between karyotypically different sibling species of the monomorphic complex, 11) show relationships among members of this subgenus and finally to iii) suggest a possible evolu- tionary scenario. Materials and methods Preparation of samples A total of 196 specimens from 21 natural populations of Agrodiaetus and 1 population of the subgenus Lysandra (Polyommatus (Lysandra) corydonius Herrich-Schäffer, 1852, otherwise known as P (L.) caucasicus Lederer, 1869), included as outgroup, were collected at several localities in Italy, France, Spain, ex-Yugoslavia and Turkey (Table 1). Since females are difficult to identify, only adult males were employed. Their wings were immediately removed with sharp scissors and the whole bodies were frozen in liquid nitrogen while still alive. Specimens were stored in this medium for several weeks, until further processing. Samples were prepared for electrophoresis as follows. Individual butterfly bodies were thawed in 250 ul of an ice-cold homogenizing solution (NADP 0.125 mM, 2-mercaptoethanol 1.14 mM ; pH range between 6-8) and macerated with an electric tissue grinder. 107 Table 1 Populations sampled Locality Country, Region Col de Cabre France, Dröme D1 (damon) Glassier di Ollomont Italy, Aosta D2 (damon) Tahir Turkey, Agri D3 (damon) Tragacete Spain, Cuenca D4 (damon) Les Puits d’Auzon France, Bouches du Rhöne L1 (dolus dolus) L’Hospitalet du Larzac France, Aveyron L2 (dolus vittatus) Pic du Cougouille France, Aveyron L3 (dolus vittatus) Ainsa Spain, Huesca Fu (fulgens) Erzincan Turkey, Erzurum Me (menalcas) Ainsa Spain, Huesca RI (riparti) Aksehir Turkey, Konya R2 (riparti) Col de Braus France, Alpes Maritimes R3 (riparti) Kocak Turkey, Van De (demavendi) Sinkan Turkey, Ankara Al (admetus anatoliensis) Küru Dagi Turkey, Canakkale A2 (admetus admetus) Nova Breznica Macedonia A3 (admetus admetus) Gevas Turkey, Van In (interjectus) Tragacete Spain, Cuenca Fa (fabressei) Oulx Italy, Torino Ex (exuberans) Pondel Italy, Aosta Hu (humedasae) Palandöken Turkey, Erzurum Ly ((L.) corydonius) Centrifugation at 13,000 x g for 15 minutes permitted the separation of a clear supernatant. Care was paid to avoid overheating during both homogenization and centrifugation. Homogenates were stored at -80°C in 5-15 ul aliquots in microtubes. Electrophoresis Electrophoresis was carried out on Cellogel sheets at 4°C, as we have found the gel form of cellulose acetate an excellent support medium. An important advantage is that it requires only 0.5-1 ul per sample per enzyme run, whereas other support media require 10-50 pl: this is a remarkable advantage for projects where many enzymes must be scored (often more than once for obtaining best results) from single very small samples. Buffer systems and staining techniques were similar to those described by MEERA KHAN (1971) and RicHARDSON et al. (1986). Genetically interpretable banding patterns could be obtained for : glycerol-3-phosphate dehydrogenase (E.C.1.1.1.8) (aGPD), adenylate kinase (E.C.2.7.4.3) (AK), hexokinase (E.C.2.7.1.1) (HK), glucose-6-phosphate dehydrogenase (E.C.1.1.1.49) (G6PD), malate dehydrogenases (E.C.1.1.1.37) (MDh-1, MDh-2), phosphoglucose isomerase (E.C.5.3.1.9) (PGI), glutamate-oxaloacetate transferases (E.C.2.6.1.1) (GOT-1, GOT-2), malic enzyme (E.C.1.1.1,40) (ME), 6-phosphogluconate dehydrogenase (E.C.1.1.1.44) (6PGD), phosphoglucomutase (E.C.2.7.5.1) 108 (PGM), esterases (E.C.3.1.1.1) (ES-1, ES-2). Isozymes and alleles were de- signed numerically according to their decreasing mobility rate. Statistical analyses Average probabilities of interpopulation genetic distance were estimated by Ner’s (1972) I and D related indexes (jackknifed according to MUELLER & AYALA, 1982), on the basis of fourteen shared loci and for pairwise combi- nations of all populations investigated. Results and discussion The cumulative total of alleles detected at the fourteen shared loci is 67 (range 3-9). Allele frequencies are reported in table 2. Nei’s genetic index D was employed to generate the cluster shown in Fig. 1. While the distance between the subgenera Agrodiaetus and Lysandra shows, as expected, a relatively high level of genetic differentiation (D = 0.625 ), the split sequence and branch lengths within the subgenus Agrodiaetus are rather unexpected. A second split separates P damon samples (D = 0.460) from all the rest. The separation between monomorphic and dimorphic forms occurs at D = 0.20. From the dendrogram the following phylogenetic reconstruction can be in- ferred: 1. Polyommatus (Lysandra) corydonius lies on a different lineage with respect to all the populations of Agrodiaetus. The latter, accordingly, may be consi- dered a monophyletic group (subgenus). 2. Within the phyletic line of Agrodiaetus, the four studied populations of P. damon group on a distinct branch. 3. Another branch includes all monomorphic populations, together with P doius, P. dolus vittatus, P. fulgens and P. menalcas. Males of both monomorphic and dimorphic forms in this phyletic line are provided with androconial scale- tufts (‘sex-brands’). The close relationships within the latter lineage support an old, non phylogenetically-based suggestion by DE LESSE (1960a), who divided Agrodiaetus into two main groups : the P. ripartii complex, including both monomorphic and dimorphic forms with androconial scale-tufts in males, and the P damon group, where sex-brands are absent. Distances between members of both complexes are indeed very small, but not incompatible with those encountered between sibling species of other groups (Mens! et al., 1988 ; 1992). The central point, in this respect, is represented by the pivotal position assumed in the dendrogram by P admetus. This is, in fact, about the only easily identifiable species within the monomorphic complex. P admetus is widely distributed from “Yugoslavia” to East Turkey and, apart from flying with many other species of the dimorphic group (P menalcas, P. hopfferi, etc.), is often encountered in cohabitation with e.g. P ripartii (Greece, Turkey, etc.), P demavendi or P. interjectus (Turkey). Since its species-level separation from all other species of the monomorphic complex 109 ST O S80 001 OOT 00’I 00°I 650 001 OT 170 O0 I OOT OOT O01I 00°I OOI 00°1 O0 O0 TT 00°1 L 9 ¢ v iE C I € C I € G I 6 8 lL 9 S Vv € C I € G I € G I € C I MT MS, Me Ba U Oy Cy hy ed RI GN IM MUT CI Ge IT a sa Ta "YIOM STU} UL Papnjaur jou suorefndod yunosoe oqui saye}i sajajfe JO uoNeIsumu Sased Jwos UT ‘arqissod jou sem SUTIOOS uonerndod ayJ ur jeu} soyeaıpur ,-, ‘Pa109S 319M suomendod je Jo SJENPIAIPUI [fe JOU aWIAÂZUS JWoS 107 "[ aJqe] ur se paroqunu are suomepndoq ‘suonepndod [7 ur 190] stydiowouow-uou paleys FI Je sarouanbai, [er € SIgEeL 110 Se t60 001 O01I 00'T 001 80°0 O0 I O0T 00 "I OOT 001 OO TI 001 00 "I O0T 0071 00°I O0 TI 00 ‘T O0T 001 a LENZ OV ely SoG ER Be It -eN TH ET CT MITA td cd Id L 9 S v € G I Ç Vv € € I 9 ¢ v b C I S v € € I (3 (6 I SNM TM BAO bit Nresierszenle tic distames 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0.0 | | | | | | | | | Fa Ly Figure 1.

All nodes shown are statistically different from zero. is unquestionable, its level of genetic divergence with respect to P. ripartii, on the one hand, and P demavendi and P. interjectus, on the other, can be taken as a yardstick to infer that all other chromosomically- identified ‘species’ within the monomorphic complex may indeed qualify as biologically distinct sibling species. Conversely, even though a more detailed analysis is required, also extending to the dimorphic species group, our results are not incompatible with the hypothesis that, in the case of Agrodiaetus, karyological mechanisms may have been involved in speciation processes. 112 Based on Nei’s rough estimates for the (highly controversial) molecular clock hypothesis, it may be possible to approximately date the branching events as follows : the subgenus Agrodiaetus originated about 3.1 Myr ago (i.e. in the late Pliocene) as dimorphic, sex brand-lacking forms (plesiomorphic charac- ters) ; monomorphism and scale-tufts appeared later, roughly 2.3 Myr ago. Finally, the ancestors of the Agrodiaetus dolus group diverged only about 1 Myr ago. The dimorphic character of this complex is therefore of a secondary origin, and may be derived from a simple reverse mutation which took place within the monomorphic complex. Speciation events within the monomorphic complex are indeed very recent, generally in the 50,000-100,000 years bp interval. These distances, however, are too small to be reliable and should be confirmed by independent studies on mitochondrial DNA. The most important exceptions, in this respect, are represented by P fabressei , P. exu- berans and P. humedasae, which, in this order, are the most primitive taxa of the monomorphic group. It may be interesting to note that, apart from P. admetus, P. fabressei is the only other monomorphic species commonly encountered in cohabitation with another species of this same complex (with P ripartii in the Montes Universales region : central Spain cf. DE LESSE, 1961c and personal observations).

Supplement No. 5 : 115-123 ; 31.X.1994 ISSN 0342-7536 A preliminary review of the classification of the zygaenid subfamily Procridinae (Lepidoptera) G. TARMANN Tiroler Landesmuseum Ferdinandeum, Feldstrasse 11a, A-6020 Innsbruck, Austria Summary In his revision of the Zygaenidae of the world, ALBERTI (1954) divides the Zygaenid subfamily Procridinae into the two tribes Callızygaenini and Pro- cridini. As typical for the subfamily, he mentions 9 main characters (“Leitmerk- male”). Three of them refer to the head and the wing, the other six to the sclerotized parts of the genitalia of the male and female. Studies of type material from all regions of the world have shown that the real autapomorhies of the Procridinae are found in the interior female genitalic structures. Of the nine characters mentioned as typical for Procridinae by Alberti, none is unique to this subfamily as all of them are shared with at least one other group of Zygaenidae. Therefore they cannot be used as autapomorphies for the Procridinae. As the type species of the tribe Callizygaenini, Callizygaena auratus (Cramer, 1779) (= nivimacula Felder, 1874), lacks the autapomorphies of the subfamily Procridinae, the tribe has to be excluded from the Procridinae and is considered to form a distinct subfamily of the family Zygaenidae. The remaining species in the Procridinae can be divided into two groups, the Adscita-llliberis-group and the Artona-group. Both are considered to form well-separated tribes within the subfamily. The Adscita-Illiberis-group has a world-wide distribution, whereas the Artona-group is restricted to the Indo- Australian and Afrotropical regions with a few species occurring also in the eastern Palaearctic region. Observations on the biology support the evidence provided by results based on morphological characters. The monophyly of the Procridinae The Procridinae are the only subfamily of the Zygaenidae with a world-wide distribution, whereas all other subfamilies are restricted to smaller areas. On the American and Australian continents they are the only representatives of the family. The nine principal characters (“Leitmerkmale” sensu Alberti) of the Procridinae are : l. Proboscis only sometimes reduced 2. Chaetosemata always present 115 . Analis [CuP] always present . Ovipositor absent . Ductus seminalis inserted into corpus bursae near orifice of ductus bursae (and not from ductus bursae itself) . Ductus bursae frequently with specialized structures . Uncus single and pointed, without sensory hairs . Valva well developed . Aedeagus never thorn-shaped Un R © \O O0 —I ON A critical review of these characters shows that not one of them is a real autapomorphy of the subfamily, as the Procridinae share most of them with at least one other subfamily of the Zygaenidae. Notes ad 1) As far as is known the proboscis is reduced in only two genera of Pro- cridinae (Theresimima Strand, 1917 [1 species] and Rhagades Wallengren, 1863 [1 of 4 species]) in which it is approximately two-thirds shorter than normal. It is fully developed in all Zygaeninae except in the relict species Pryeria sinica Moore, 1877, and in nearly all the Chalcosiinae except a few genera in which it is shorter (e.g. Aglaope Latreille, 1809, Chalcosiopsis Swinhoe, 1894, Boradia Moore, 1879). It is partly reduced in the Phaudinae and totally absent in the Anomoeotinae and Himan- topterinae. These three groups are treated as subfamilies of the Zygaeni- dae by ALBERTI (1954). The Anomoeotinae and Himantopterinae are now accepted as distinct families within the superfamily Zygaenoidea and the Phaudinae may also form a separate family perhaps including the Lactura-group according to larval and female genitalic characters (Kirky, pers. comm.). Within the remaining three subfamilies of Zygae- nidae, the Zygaeninae, Chalcosiinae and Procridinae, the character ‘proboscis only sometimes reduced’ does not represent an autapomorphy of the Procridinae. ad 2) Well developed chaetosemata are present in all Zygaeninae, Chalcosiinae and Procridinae. The presence of chaetosemata is therefore a family character of the Zygaenidae. ad 3) The vein CuP (analis sensu ALBERTI, 1954) is present in all Zygaeninae, Chalcosiinae and Procridinae. It is therefore a family character of the Zygaenidae. ad 4) Absence of an ovipositor occurs in all Zygaeninae and in all Procridinae, except the Central American genus Gonioprocris Jordan, 1913 in which a small ovipositor is developed. A well developed ovipositor is present in the Chalcosiinae. As this character is shared by both the Zygaeninae and Procridinae it cannot be an autapomorphy of the subfamily Pro- cridinae and is considered to be plesiomorphic. ad 5) The ductus seminalis is inserted into the ductus bursae near the antrum in the Zygaeninae and in some Chalcosiinae (e.g. tribe Heteropanini), 116 but arises from the corpus bursae in most Chalcosunae and all Procri- dinae. Therefore this character does not represent an autapomorphy of the subfamily Procridinae. ad 6) The ductus bursae has many very strange and specialized structures in most Procridinae but there are also groups within this subfamily in which the ductus is simple. The specialization of the ductus bursae (e.g. the evolution of a praebursa) is a good autapomorphy for certain subgroups of the Procridinae but not an autapomorphic character for the entire subfamily. ad 7) It is true that nearly all Procridinae have a single and pointed uncus mainly without any sensory hairs. All Zygaeninae and many Chalcosiinae (e.g Chalcosiini) have a double uncus. In those Chalcosiinae in which a single uncus is developed (e.g. Cyclosiini), it is rarely pointed and bears sensory hairs. Nevertheless there are some Chalcosunae which have a single uncus which lacks hair (e.g some Cyclosia Hübner, [1820]) and there are specializations of the uncus known in some Procridinae (e.g. Neoprocris Jordan, 1915). Therefore this character is also not a good autapomorphy of the subfamily Procridinae. ad 8) All Zygaeninae, Chalcosiinae and Procridinae have a well-developed valva which is a plesiomorphic character. ad 9) The aedeagus is thorn-shaped in the tribes Agalopini, Aglaopini and Chalcosiini of the subfamiliy Chalcosiinae, but normal and tube-like in the tribes Cyclosiini and Heteropanini. In all Zygaeninae and Procridinae it is not thorn-shaped. The character "aedeagus never thorn-shaped’ does not represent an autapomorphy of the subfamily Procridinae. Although according to recent research the characters of Alberti do not re- present good autapomorphies of the subfamily there is no doubt that this group is a monophyletic unit and its status as a subfamily of the Zygaenidae is justified. The main characters that clearly separate the Procridinae from all other Zygaenid subfamilies are : 1. Female genitalia with ductus seminalis lacking pseudobursa or bulla seminalis. As in most families included in the superfamily Zygaenoidea, there is a well- developed pseudobursa present in the Zygaeninae and Chalcosiinae. The lack of a pseudobursa in the Procridinae is therefore considered to be a secondary reduction, or plesiomorphic. 2. Lagena in receptaculum seminis absent. In Zygaeninae and Chalcosiinae and, as far as checked, in all other families included in the superfamily Zygaenoidea a well-developed lagena is present, as in most ditrysian Lepidoptera. The reduction of the lagena in the Procri- dinae is therefore considered to represent a good autapomorphic character of the group. 17 3. A pair of accessory glands is present close to the ooporus which may represent a structure homologous to Petersen’s gland in the Zygaeninae. These glands differ in shape and structure from those of the Zygaeninae. They are lacking in the Chalcosiinae. There is one group of Procridinae in which these glands are secondarily reduced or transformed into a different structure (Pollanisus Walker, 1854, Hestiochora Meyrick, 1887 and Onceropyga Turner, 1906 in Australia). According to recent research Petersen’s gland in the Zygae- ninae produces a secretion which is supposed to prevent predators and possibly funghi from attacking the eggs (Naumann, pers. comm.). As the Australian group is not able to produce this liquid due to the absence or the modification of the glands another defence system has been developed. The females of the three above-mentioned Australian genera are characteristized by their abdominal hairtuft. When laying eggs the long, hair-like scales of this hairtuft are glued to the surface of the eggs, giving the egg clusters a hedgehog-like appearance. The tips of these scales are poisonous and an aphid, for example will die within a quarter of an hour after touching them. It is therefore possible that the glands have evolved into a special subcuticular poisonous area in which the spiny scales are situated. When the scales become attached to the egg by their distal part, the proximal part is covered with poison as in a poisonous dart. 4. Larva without chemical defence system. In the larvae of Zygaeninae and Chalcosiinae a special cuticular defence system is present (PovoLNY & WEYDA, 1981 ; FRANZL & NAUMANN, 1984; 1985 ; WITTHOHN & NAUMANN, 1984a ; 1984b). Similar defence systems have also been discovered in other Zygaenoidea (Naumann, pers.comm.). It is not yet clear whether the lack of such a cuticular defence system in larvae of the Procridinae is a secondary loss or a primary situation. The subdivision of the Procridinae into tribes ALBERTI (1954: 209), in his revision of the family, divided the subfamily Procridinae into the two tribes Callizygaenini and Procridini. He was con- vinced that both are monophyletic units within a monophyletic subfamily. His opinion was based on studies especially of genitalia structures and the presence or absence of a medial stem in the wing venation. Unfortunately Alberti did not check Callizygaena aurata (Cramer, 1779)(— nivimacula Felder, 1874), the type-species of Callizygaena Felder, 1874. This species and a small group of other congeneric South East Asian species lack the characteristic autapomorphies of the subfamily Procridinae. The following characters show that the Callizygaena-group neither belong to the Procridinae nor to the Zygaeninae or Chalcosiinae : l. Valva dish-like and strongly sclerotized as in Zygaeninae, with setae at distal margin pointing inwards but with one single, stout, triangular, not 118 distally pointed and very strongly sclerotized uncus (in the Zygaeninae there is a double-lobed uncus present and in the Procridinae and Chalcosiinae the valva is completely different, never so strongly sclerotized and distally rounded) (Fig. 1). Fig. 1. Male genitalia (Valva-tegumen-uncus-part) of Callizygaena aurata (Cramer, 1779), S. India, Mullacore (BMNH/London). 2. Aedeagus a tiny, slender and straight spine (in Procridinae tube-like and much larger compared with the size of the specimens and in the Zygaeninae also much larger with a lamina dorsalis and lamina ventralis present). 3. Corpus bursae with characteristic signa (signa never present in the Pro- cridinae). 4. Ductus seminalis arising from.the proximal part of the ductus bursa and not from the corpus bursae (as in the Procridinae) or from the distal part of the ductus bursae (as in the Zygaeninae). 5. A pseudobursa (= bulla seminalis sensu Alberti) is present, as in the Zygae- ninae and Chalcosiinae (absent in the Procridinae). 6. Receptaculum seminis with well developed lagena, as in all Zygaenoidea except the Procridinae. A) 7. Petersen’s gland or homologous structures absent (present in the Zygaeninae and Procridinae, also absent in the Chalcosiinae). Consequently, the Callizygaena-group of the Zygaenidae has to be excluded from the subfamily Procridinae and treated as a distinct subfamily of the Zygaenidae, Callizygaeninae stat.n. According to the author’s studies the remaining genera of Procridinae can be placed into two subgroups or tribes : (a) Tribus Procridini Boisduval, [1828] (b) Tribus Artonini trib. n. The tribe Procridini is still a mixture of several monophyletic subgroups which may be described as separate tribes later, if necessary. The tribe Artonini is a monophyletic unit based on the following autapomorphies : 1. Chaetosema triangular, extending forward between the compound eye and the ocellus (Fig. 2). In all other Procridinae the space between the compound eye and the ocellus is covered with smooth, flat scales and the chaetosema is not extended. Fig. 2. Chaetosema of a primitive Artonini from Australia. SEM-photo by Colin Beaton, CSIRO, Canberra, Australia. 120 4 @ Fig. 3. Lateral view of a female Turneriptocris coronias (Meyrick, 1886) with dorso- lateral evagination at abdominal segment 2 (see arrow). Photo by John Green, CSIRO, Canberra, Australia. 2. Abdomen with small dorsolateral evaginations on segments 2 and 7 (Fig. 3). These evaginations are secondarily reduced in some subgroups. Only on the second abdominal segment are these lateral evaginations present in the Australian genus Pollanisus Walker, 1854, and there are no lateral evagi- nations in the Australian genus Hestiochora Meyrick, 1887, but as Hestio- chora is closely related to Pollanisus and there are clear synapomorphies indicating the monophyly of these two genera, the reduction of the lateral evagination has to be interpreted as a secondary loss. 3. Valva fan-shaped with a stronger, sclerotized costal and basal margin and a very translucent, strongly folded central part. This type of artonoid valva is present in its basic and simple form in the primitive Australian genera (e.g. Pollanisus Walker, Fig. 4) while it has evolved into very complicated structures in most of the tropical genera. However, even if the structures are very complicated the ground-plan of the fan-shaped artonoid valva is still visible. The Procridini have a world-wide distribution with the exception of the tem- perate parts of Australia. The Artonini occur only in the Afrotropical Region, in South East and East Asia and Australia, including the temperate parts and the island of Tasmania. Conclusion Having excluded the former tribe Callizygaenini from the subfamily Procri- dinae, the remaining genera within the latter form a monophyletic unit. The 121 Fig. 4. Artonoid valva type of a primitive Artonini, Pollanisus subdolosa (Walker, 1865), male Holotype, Australia (BMNH/ London). monophyletic origin of the Procridinae is supported by four autapomorphies. The subfamily is newly divided into two tribes. The tribe Procridini consists of several monophyletic groups and subgroups, but at the present time there are no characters known which are clear autapomorphies of the whole tribe. The tribe Artonini is monophyletic, based on three autapomorphies. The Calli- zygaeninae are considered to form a distinct subfamily of the Zygaenidae. References ALBERTI, B., 1954.
