AMSTERDAM CONTENTS Systematic part (continued) SCHOENOTENIDAE 3 Chlidanotidae 113 Carposinidae 115 COPROMORPHIDAE 162 Publication of the present paper has been made possible by a grant of the “Nederlandse Organisatie voor Zuiver- Wetenschappelijk Onderzock” covering a large part of the eocpenses for printing. DRTOKEELJ HOLLAND N.V., AMSTERDAM The present paper forms the third part of the report on the Micro- lepidoptera of the Third Archbold Expedition to the Netherlands New Guinea, 1938 — 1939. The previous parts were published in no. 1, pp. 1 — 167, 1952 and in no. 3, pp. 1 — 166, of this volume. In the present part are given descriptions and records of the Schoeno- tenidae, the Chlidanotidae, the Carposinidae and the Copromorphidae. 13 genera and 105 species are described as new. SCHOENOTENIDAE This recently described family forms the most novel and therefore, perhaps, the most interesting feature of the present collection. It is so richly represented — seven genera and 77 species are described or recorded below — that it seemed worth while to use this opportunity for presenting a brief synopsis of the whole group. We reviewed all the genera that are known at present. Reviews of those not represented in the collection of the Expedition are printed in small type. As this family has been described and its affinities, distribution, and possible origin have been discussed at some length quite recently (Diakonoff, 1952, Zool. Meded. Mus. Leiden, Vol. 31, pp. 165 — 170, figs. 1 — 5), we need not return to this matter here. It may suffice to give a map of the distribution of the Schoenotenidae, as far as our data allow at present (fig. 373), and to present a key to all the genera known, in addition to the provisional key in the above mentioned publication. These data, however, increase continually, and the number of additional, as far undiscribed forms at our disposal is considerable. We anticipate, therefore, a quick growth of this newly born group. The importance of this family for our insight in the taxonomy of the higher units of the Tortricoid superfamily seems to be considerable. As far as we can see its affinities now, it might represent a link between the tortricoid groups sensu striclo, viz. Tortricidae at one side, and the as far rather obscure Copromorphidae at the other — and through them indicate a connection, or, perhaps, one of the polyphyletic connections between the above mentioned superfamily and the Tineoidea sensu lato.

Uncus small, hook slender, simple. Socius small, pending. Gnathos moderate, normal, hook slender. Transtilla extremely strong: an erect-quadrate plate with rounded, finely dentate labides, and a long, strong, spike- like porrect projection at each side of lower edge of this plate. Valva very small, membraneous, strongly narrowed, fine-bristled, sacculus strong, sclerotized, ending in an acute thorn. Vinculum rather large, chitinous, subquadrate. Aedoeagus long, curved in middle, apically becoming narrow and strongly sclerotized, ending in a large spike. Comuti not perceptible. (Slide No, 751 D.) Limen a strong straight transverse band, dilated laterally, and with a longitudinal fold. Ostium very wide. Colliculum strong, subcylindrical, dilated above, rather long, irregularly plicate below. Ductus bursae short.. Bursa eopulatrix ovoid. Signum, a moderate smooth and acute tooth. Eighth tergite sclerotized. Ovipositor lobe subtriangular, rather tortrieoid (Slide No. 752 D.) Genitalia of Proselena niphostrota Meyrick (figs. 395, 390). Tegumen and uncus very much like those in the preceding species, somewhat broader. Socius longer. Gnathos broader, but weak, angulate, not pending. Transtilla slender, a transverse, V-shaped moderate band. Valva larger, less narrowed, sacculus little chitmised, ending in a blunt point. Vinculum strong, erect-rectangular. Aedoeagus chitinous, base bulbate, apex slightly curved. (Slide No. 753 D.) Limen a broad, slightly curved transverse band, somewhat plicate below. Colli- culum slender, elongate, narrowed above. Ductus bursae narrow, long. Bursa eopulatrix subspheroid, simple. Eighth tergite elongate. Ovipositor lobe elongate, rather narrow, lower fourth narrowed and curved : schoenoteniform. (Slide No. 754D.) Nearly allied to the following, this genus is a specialised off-shoot of the Schoenotenes branch. There are two small Australian and two closely allied New Zealand species. The transtilla in Proselena annosana is of the same type as in Paraselena thamnas, and shows a correlation with the genus Stenotenes. Mr Bradley, of the British Museum, kindly sent us specimens of both the above mentioned species for study. Proselena spec. Iebele Camp, 2250 m, November — December, 1938. One specimen, almost entirely denuded. The neuration shows all the peculiar characters of the genus, but the size is exceptionally large: 24 mm.

Palpi moderate, porrected, second joint dilated with rough scales above and beneath, terminal short. Thorax smooth. Forewings with 7 and 8 stalked, 7 to termen. Hindwings with 3 from much before angle, remote and nearly equidistant from 2 and 4, 4 from angle, 5 rather approximated to 4 at base, transverse vein very oblique, 6 and 7 long-stalked”. MICROLEPIDOPTERA OE NEW GUINEA 9 Genotype Paraselena thamnas Meyrick, 1910 (Australia). We had no opportunity to study representatives of this genus, but Mr. Bradley kindly provided us with a sketch of the neuration of the unique type specimen of P. thamnas (fig. 382), and with photographs of the genitalia of the type, a male (fig. 393), here reproduced by the courtesy of the Trustees of tho British Museum. After studying this sketch we can add the following particulars to the Meyrick ’s description of the genus. Fore wing with lb furcate along basal 1 / :! , 2 from middle, 3—5 closely approximated from angle, 10 from 3 / 4 , 1 1 from about middle of cell, parting vein from l /j of upper edge of cell to between bases of 5 and 6. Hind w'ing with 2 from about a / 3 , transverse vein weak, 6 and 7 long-stalked, from base, connected by a transverse bar with two- thirds of the distance of upper edge of cell between base of w’ing and base of vein 5; 8 strong, from base. The genitalia, as far as we can read the photograph (fig. 393), may bo described as follows. Tegumen broad, triangular. Uncus with a triangular base, ending in a slender simple hook. (Socius not percep- tible.) Gnathos, an angularly bent, pending rod. Transtilla extremely strong: a trans- verse broad band, with upper edge slightly excavate in middle and short-dentate, lower edge with two strong, little curved pending appendages. Valva with a slightly curved cucullus, sacculus 1 / 2 , strong, ending in a transverse long spike. Aedoeagus moderately bent in middle, ending in an acute transverse hook. Cornuti a slender dentate band. (Genit. Slid© No. 6742 B.M., Gates Ci.arke fecit.) The peculiar sclero- tized transtilla strongly resembles that i: fig. 400). and that in Pvoselena annosuna.

Genotype Schoenotenes synchorda Meyrick, 1908 (India, Java). A genus of considerable extent, forming a typical feature of t he Papuan Fauna; it seems very probable that New Guinea also is the country of its origin, in comparison with the number of species from that island (and from the Bismarck Islands) which are already known or described below, Schoenotenes is but poorly represented in Australia, in the Malayan Region and in India. The genus is easy of recognition, and its representatives can be arranged in a natural series, beginning with the species of Copromorphid facies: with ovate roughish fore wings, of which the veins are strongly raised, and with semipellucent hind wings. The male genitalia of this older group possess a narrow uncus, strong hami, and small or no socii and a relatively simple valva, while the female genitalia show an intricate development of the strongly sclerotized genital segment. The antipodes of this group are the species with Tortricid facies: subtriangular fore wings which are rather smoothly scaled, except for the invariably present plical and discal scale-tufts, and with a normally scaled, subtrapezoid hind wing, of which the cell is rather broad and the closing vein not so strongly oblique as in l ) As an exception veins 7 and S in the fore w'ing are stalked in a single species, with the stalk of these veins of inequal length in the left and in the right wing of the unique specimen. Therefore we are inclined to explain this situation as anomalous. MICROLEPIDOPTERA OF NEW GUINEA 33 the preceding group. The male genitalia are of the Tortricoid type, without hami, with pending socii, with a strong gnathos, and a simple valva of Cacoeciine appearance. This group forms the natural connection with the family Tortricidae. The two above mentioned groups are connected with each other by a long series of species intermediate as to the shape and the scaling of the fore and the hind wings, and as to the shape of the genitalia ; these intermediate forms have a robust, sometimes curiously shaped gnathos, and a valva with a bristled knob at the top of the sacculus. In many species the sacculus bears a patch of curious, flattened, and bifid bristles. Distribution of the genus Schoenotenes outside the Papuan region is as follows : Australia : seven species, Sumatra : one, Java : two, India, Malaya and Sumatra: one, India and Java: one species, altogether twelve species. Furthermore one undescribed species has recently been collected by the author in South Celebes, another was received from the Moluccas. The following species are apocryphic: Schoenotenes circensis Meyrick 1928, Exot.

CHLIDANOTIDAE This little known, small family, although of doubtless tortricoid relationship, up till now seemed to occupy an isolated position. It is very probable, however, that a study of the genitalia of its species, which are hardly known at present, will reveal interesting facts. The genus Picroxena Meyrick, e.g., appears to be correlated with certain forms of Schoenotenes, as its male genitalia are in the possession of the hami. We regard the present family as being immediately related to the Schoenotenidae, and possibly a development of them, judging from the stalked veins 8 and 9 in the fore wing which is a character of considerable specialisation. Although the following genus gives no doubt as to its place in the present family, it possesses several characters new to the group, viz., the origin of the vein 2 in the fore wing and the presence of a short basal pecten on the lower edge of cell in the hind wing. The following species is a second record of the family from the Papuan region. Key to the Papuan genera of the Chlidanotidae 1.

CARPOSINIDAE This family forms a natural and very distinct group, and stands isolated. In consequence of the last mentioned fact it has been subject to frequent rearrangements in the system, and was moved back and forth between the groups “Tortricina” and “Tineina”. It seems advisable for the time being to let it keep an intermediate position between these two groups. Meyrick has pointed out (1922) that the family must be of considerable antiquity and in a stage of decline. Many forms being extinct, it is difficult to ascertain the true affinity of the Carposinidae. It is possible, however, that new forms belonging to this family will be found though, to prove that it might form a connection between the two above mentioned groups of families. The existence of the family Carposinidae, ipso facto, makes an absolute separation of a superfamily “Tortricoidea” from “Tineoidea” problematic. That such a separation is artificial has recently been stipulated by the late A. Jefferis Turner, shortly before his death ( Proc . Linn. Soc. N.S. Wales, vol. 71, p. 303, 1947), and also by Dr. A. J. T. Janse [Moths of 8. Africa, vol. 1, pp. 60 — 61, 1936). The neuration of the hind wing in Carposinidae is typical by constant reduction of one of the M-branches, either M 3 or M 2 . It is not easy to ascertain which of these veins is lacking. Meyrick, who was the first to 116 MICBOLEPID OPTEBA OF NEW GUINEA define the family, as far back as 1881, regarded the absent vein as vein 5 (M 2 ), and maintained this view in his “Revision of' the Australian Tortricina” in 1910. But in 1922, in his study of this family in the Genera Insectorum he indicated the permanently lacking vein as vein 4 (M 3 ), without giving an explanation as to what caused this change of opinion, and stated that veins 3 and 5 can be separate, approximated or stalked. Perhaps the termination of the vein which follows upon vein 3 in the hind wing, high up on the termen, brought him to this conclusion. When describing the genus Commatarcha in 1935 he stated, on the contrary, that veins 3 and 4 in hind wing are stalked and that it is again vein 5 which is absent in that genus. We are inclined to share the original opinion of Meybick, that the hind wing in this family permanently lacks vein 5, not 4, on the ground of the consideration that the remaining veins are often stalked and that these must therefore be 3 and 4, not 3 and 5, as the occurrence of 3 and 4 originating from a common stalk is very common in Microlepidoptera. The following vein in the hind wing of Carposinidae which is apt to reduction, is vein 6 (M x ). The fact that the remaining, not reduced, vein invariably terminates in the apex of the hind wing, confirms the surmise that this must be vein 7 (Rs), even when this vein originates below the upper angle of cell, and that the lacking vein is vein 6 indeed. The infrequent occurrence of a developed vein 6 in the hind wing must be regarded as an archaic character, as was put forward by Meybick. However, this character is not absolutely reliable, as in the extensive genus Meridarchis Zelleb, 1867, this vein occurs in different stages of development: from fully developed to entirely obliterate, as is set forth below under remarks on this genus. Obviously the old genus Meridarchis reflects in the development of its species the course of the development of the genera of the entire family Carposinidae, in the same way as does Schoenotenes in the family Schoenotenidae. The family represents a very natural group, showing a great uniformity of facies. About three common patterns of markings prevail throughout the species, often independently of the genus to which these belong: (1) a large median costal trapezoid spot and a well-defined basal patch; (2) some six discal dots with a small dot on base of costa and one above dorsum beyond base; (3) evenly suffused wing with a transverse, light comma-shaped mark on closing vein. The tenacity of quite different species to one of these three patterns is often confusing ; thus a Carposina species as well as a Meridarchis can bear the first pattern of markings mentioned; a Meridarchis, as well as a Heterogymna, the second; and a Heterogymna (e.g. H. xenochroma spec, nov.), as well as a Bondia, the third pattern, etc. The male genitalia of the New Zealand Carposina species have been described and figured by Philpott {Trans. N. Zeal. Inst., vol. 59, pp. 476 — 477, figs. 1 — 11, 1929). His figures clearly show the type of the 1 MICROLEPIDOPTERA OF NEW GUINEA 117 family, and we can add no new general points to his descriptions, at least as far as the present Papuan material is concerned. The valva often possesses a small discal projection which with Philpott we indicate with the name of ampulla. A second, often long digitoid projection can sometimes be found in the middle of the base of the valva. The anellus may be equipped with long erect projections and is then called furca. The vitta (Philpott), a peculiar terminal filament of the aedoeagus, is in our material invariably missing; it is either altogether absent or possibly broken. The cornuti may be considerably developed, as e.g. in Anomoeosis phanerostigma spec. nov. As to the female genitalia, these are of a peculiar development and mostly well-differentiated. Ovipositor moderately long, erectile, telescoping. Ostium, a broad fold. Limen, often with one or three erect pointed projections and sometimes with two more large erect processes ventrally from these. Ductus bursae is strongly swollen along its proximal half and forms a large sack with retinate or finely papillate surface. Bursa copulatrix is large, elongate or even tubular. Signa, two, each with a flattened or concave proximal plate, bearing two slender horns with a finely dentate inner edge and a curved acute point. As Philpott rightly states, this type of the genitalia of the New Zealand Carposinidae has nothing in common with the genitalia of the Tortricoid families. Also in this respect the present family makes the impression of standing quite isolated, as is said above. However, our present knowledge of the genital characters of Carposinidae is too fragmentary to allow of any certain conclusions in that respect. It is possible that not the prevailing type of the genitalia as described above is the type which will be useful for phylogenetic hypotheses, but that one will have to look in the direction of deviating — perhaps more recent — forms. The male genitalia of several Carposinidae from Java and Sumatra, recently described, deviate considerably from that “archaic” type and are, therefore, interesting; some remind one of a certain type frequent in the Eucosmidae (Metacosmesis barbaroglypha Diakonoff, Treubia, vol. 20, p. 49, fig. 6, 1949); others are decidedly of a tortricid type (Mesodica infuscata Diakonoff, ibidem, p. 44, fig. 7). The country of origin of the present family appears to be South East Asia, which is supported by the distribution of the “archaic” forms i.e. those in possession of a developed vein 6 in the hind wing. One genus with this character is known from Australia ( Sosineura ), one from Japan (Conmiatarcha ) , one from Java {Mesodica), one from Java and Ceylon {Metacosmesis), and three from New Guinea. These last mentioned genera, which are described below, viz., Blipta, Xyloides, and Hystrichomorpha, certainly possess archaic features and facies ; Hystrichomorpha even forms in some respects a connection with the family Copromorphidae. Meridarchis which is often also in possession of a developed vein 6 in the hind wing, as is said above, is rather wide-spread and occurs throughout India, 118 MICROLEPIDOPTERA OF NEW GUINEA Ceylon, Java and New Guinea to Australia, with a straggler in Congo, but seems to originate from India.

The characteristic feature of the veins 8 and 9 in the fore wing being stalked makes this extensive genus easily recognisable; the veins 3 and 4 may be stalked or separate. The hind wing shows also variable venation, veins 3 and 4 being stalked, closely approximated or remote; vein 5 is invariably absent. An interesting feature is that vein 6 in the hind wing may be present and fully developed, as in the genotype, M. trapeziella Zeller, from India and Java, in M. (— Autogriphus) lutea Walsingham, from South Africa, in M. (= Propedesis) excisa Walsingham, from Japan, and in several of the following Papuan species; in other species vein 6 is either weak, but traceable along three-fourths of its length, reduced to a 120 MICROLEPID OPTEEA OP NEW GUINEA minute basal trunk or entirely absent. An example of the latter situation is M. (= Tribonica) eremitis Meyrick, from Ceylon. It is strange that the unstable nature of this vein in M cr idarchis seems to have escaped attention, as we find no record of this fact by other authors. It is not possible to separate the genera Meridarchis and Tribonica by the aid of this feature, as not only gradual transitions can be found connecting separate species together, but also in individuals of the same species, and even in left and right hind wing of a single specimen vein 6 may be differently developed. This is rather unsatisfactory in view of the importance ascribed by Meyrick to the presence or absence of this vein. We were accordingly obliged to revise the above key to the genera of the Carposinidae. In all the following species the labial palpi in the male are rather short and subascending, in the female only moderately long, or even short and porrect but tending to be subascending (M. anisopa spec, nov.); the terminal segment in the two sexes is very short, exposed and narrowed.
