LARVAL AND PUPAL DESCRIPTIONS OF
MARILIA FUSCA (TRICHOPTERA: ODONTO-

CERIDAE) 1

H. Gene Drecktrah 2

ABSTRACT: The larva and pupa of Marilia fusca from Australia are described and
illustrated.

The genus Marilia is composed of two species in Australia: M. fusca
Kimmins and A/. 60/aMosely (Neboiss 1983, 1986). Additional species of
Marilia have been recorded from Oriental regions, China and South and
North America (Wiggins 1977). Both Australian species were reported to
have the same distribution: New South Wales and the southeast coastal
ranges of Australia (Neboiss 1983). M. fusca was described by Kimmins
(Mosely and Kimmins 1953) from adults taken at Epping, NSW, but no
descriptions of the immature stages were included. This is the first
recorded association of the immature stages of M. fusca with that of the
adult. Identification and association of the immature stages, based on
two pharate males, were made by Dr. A. Neboiss, Curator of the Entomol-
ogy Department, Museum of Victoria, Melbourne, Australia.

Ulmer (1955) described and illustrated the larvae and pupae of M
sumatrana Ulmer from Sumatra and Java (Sunda Islands). Wiggins
( 1977) provided generic characteristics and the description of M.flexuosa
from North America. The other North American Marilia, M. nobsca
Milne, has been associated with the adult (Wiggins 1977) but apparently
no descriptions nor illustrations were published. The pupae of M. major
Muller and M. minor Muller from South America were described by
Thienemann (1905). Unfortunately, the larva of the other Australian
species, M. bola, is not known. The larvae of M. fusca, M.flexuosa and M .
sumatrana share several characteristics: metanotal setal area 1 (=sa\)
sclerites large and rectangular; metanotal sal sclerites small and rec-
tangular; fore tibia approximately same length as tarsus; labrum with 6
long setae across central part; anal claw lacking dorsal accessory hook;
and lateral sclerite of anal proleg edged mesially with stout spines.

There are, however, several characteristics that can be used to dif-
ferentiate these three species. In M. fusca and M.flexuosa, the mesonotal
plate is subdivided into 3 sclerites, whereas in M. sumatrana the mesono-
tal plate is not subdivided. The ventral apotome of M.flexuosa and M.
sumatrana completely separates the genae, but in M. fusca, the ventral

apotome separates the genae to approximately the midpoint of the
ecdysial line. The anterolateral corner of the pronotum of M. flexousa
andM. sumatrana is rounded; in M.fusca it is slightly pointed but not pro-
duced into a sharp point as in two other genera (Parthina and Psilotreta)of
North American odontocerids (Wiggins 1977). In M.fusca and M.flex-
uosa, the lateral sclerite of the anal proleg possesses 3 very long setae on
the mesial margin, whereas M. sumatrana possesses a dense cluster of
setae at the apex of the hind tarsus; this cluster of setae is lacking in M.
flexuosa and M.fusca.

The pupae of M.fusca, M. sumatrana, M. major and M. minor can be
separated on the basis of the teeth (serrations) of the anal processes. In M.
sumatrana, several prominent teeth are located on the hooked apex of the
anal process. In M.fusca, a few low teeth are found just proximad of the
apical hook with one small tooth on the inner margin of the hook. The
anal process of M. major has several prominent teeth ending con-
siderably proximad of the apical hook. In M. minor prominent teeth
extend to the base of the apical hook. The pupal mandibles of these four
species are basically similar, i.e. thick basally with a flattened bladelike
distal portion which is strongly attenuated. In M.fusca the attenuated
portion is approximately equal in length to the distal bladelike portion;
in M. major and M. minor, the attenuated portion is less than half the
length of the bladelike portion. The tip of the attenuated portion of the
mandible of M. sumatrana is subdivided into several small points (or
teeth), whereas, in M.fusca, the tip of the mandible is simply pointed.

MATERIALS AND METHODS

The specimens of M.fusca used to describe the immature stages were
collected in the Yarra River near Reefton, Victoria, Australia. Illus-
trations were prepared from specimens preserved in 80% ethanol using a
squared ocular grid in a stereo binocular microscope. For greater detail,
larval and pupal structures were dissected, mounted in Hoyers mount-
ing medium on a microscope slide, and examined using a compound
microscope at 100X-400X magnifications. Measurements were made
with a calibrated ocular micrometer or the squared ocular grid.

A NEW XYELA (HYMENOPTERA: XYELIDAE)
FROM WESTERN UNITED STATES 1

David R. Smith 2

ABSTRACT: Xyela lata, n. sp., is described from Colorado, Nevada, and Oregon. Adults
were collected from Pinus flexilis and Pinus monophylla.

Larvae of Xyela feed on the developing pollen of the male strobili of
pines. Species of the genus probably occur wherever pines are found.
Adults are small and short-lived and may be found on the larval host
plant or on nearby pollen sources such as the catkins of willow, alder, or
birch. Because of their small size and habits, there are undoubtedly a
number of species yet to be discovered. One unusual new species has
recently come to my attention and is described here.

Burdick's (1961) revision of Xyela included 15 species in the North
American fauna and notes on the biology of some. Since then, two
species have been added (Smith, 1979). Smith (1978) listed 32 world
species.

Hosts. Adults were collected from Pinus flexilis James and P. monophvlla Torr. &
Frem. Hosts may include several species of pine, as is the case for some other Xyela
species.

DISCUSSION

In Burdick's (1961) key, this species runs to bakeri Konow, buibakeri
is commonly mostly black, the lancet has no apical notch or distinct
annuli, and the sawsheath is less than 2 mm long. The extremely broad,
straight, laterally flattened sheath and the constricted apex of the lancet
are unique loX. lata and are not known in any other Xyela. These unusual
characteristics will immediately distinguish this new species.

Some variation occurs in the amount of yellow, especially on the dor-
sum of the thorax and venter of the abdomen. The mesonotum may be
almost all black to dark brown, or the yellow spots on the lateral lobes
and scutellum may be extensive; the abdomen may be mostly black ven-
trally and laterally, or mostly yellowish.

Collections are from high elevations, as indicated by label data about
5400' or above.

The specific name is from the Latin "latus", referring to the unusually
broad sawsheath.

SOCIETY MEETING OF NOVEMBER 29, 1989
NORTH AMERICAN BIRD BLOW FLIES AND MAGGOTS

(PROTOCALLIPHORA)

Dr. Curtis W. Sabrosky, Speaker

About a quarter of all species of North American perching birds have been found infested
with maggots of blow flies. These blood sucking parasites feed on nestling birds, engorging
themselves two or three times before pupating in the bottom of the nest or falling to the
ground to pupate. Although the iridescent blue-black or coppery-colored adults are rarely
seen except when reared, they have a very long life span and probably overwinter in this
stage even in the north of Canada and Greenland. Dr. Curtis W. Sabrosky, retired from the
USDA Systematic Entomology Laboratory and former president of the Entomological
Society of America, described these little known flies at the society meeting at the Academy
of Natural Sciences of Philadelphia. He has recently coauthored a book on the taxonomy,
biology and ecology of the Protocalliphora.

Twenty-six species of bird blow flies are recognized in North America; however, subtile
key characters make their identification difficult. While the different species are somewhat
stratified vertically in a woodland habitat and have distinctive geographical distributions,
there is little host specialization. For example, one species, P. braueri (Hendel), has been
found in the nests of 42 bird species and nine Protocalliphora have been found in robin
nests. Once 1200 maggots were found in a single hawk nest. Only ground nesting, shore
birds and birds of the lower Mississippi Valley and Gulf Coast seem to be spared from these
parasites.

Dr. Sabrosky 's lecture was attended by 19 members and 6 guests who came early and
stayed late to talk about insects. Perhaps it was the mulled cider or refreshments that put
everyone in a good mood. Among a number of topics discussed in the open forum before
the featured talk was the preservation of habitats by Jane Ruffin. Cape May. New Jersey has
long been recognized as a place where migrating birds and insects pause to feed before con-
tinuing their annual southward migration. The rapid development in Cape May County is
reducing the cover and resources normally used by migrants such as the monarch butter-
fly. Mrs. Ruffin urged members to write letters supporting efforts to preserve existing old
growth and to create new backyard habitats that will sustain migrant birds and insects in a
residential setting.

A NEW RHADINOCERAEA (HYMENOPTERA:

TENTHREDINIDAE) FEEDING ON ZIGADENUS

(LILIACEAE) FROM SOUTHEASTERN

UNITED STATES 1

David R. Smith 2 , Will McDearman

ABSTRACT: Rhadinoceraea (Veratra)zigadenusae, n. sp., is described from the southeas-
tern United States. Young larvae feed on the developing stamens and pistils and older lar-
vae consume open flowers of Zigadenus densus and Z. leimanthoides. The species is
described and illustrated and notes on its life history are given. Plants of the tribe Veratrae
(Liliaceae) possess alkaloids toxic to many animals, and species of Rhadinoceraea (Veratra)
are among the few herbivores of this tribe.

Sawfly larvae feeding on flowers of Zigadenus densus(Descr.)Fema\d
and Z. leimanthoides A. Gray were discovered by the junior author dur-
ing studies on the relationship between plant fecundity and herbivores.
Examination of the adults associated with these larvae revealed a new
species of sawfly of the genus Rhadinoceraea. This new species resembles
the only other eastern North American species of the genus, Rhadi-
noceraea nubilipennis (Norton).

Eight North American species of Rhadinoceraea were treated by
Smith (1969), four in the typical subgenus and four in the subgenus
Veratra. All occur west of the Rockies except for R. nubilipennis. Known
hosts are Calochortus sp. for R. (R.) nigra (Rohwer) and Veratrum spp. for
R. (V.) aldrichi (MacGillivray), R. (V.) insularis (Kincaid), and R. (V.)
nubilipennis. Zigadenus represents a new host plant for sawflies. All hosts
are in the family Liliaceae.

Remarks. This species runs to R. nubilipennis in Smith's ( 1969) key to
North American Rhadinoceraea. In general habitus, color, and size it is
similar to that species, but close examination reveals differences in the
female sheath and ovipositor and the male genitalia. The female sheath
is much smaller than that of R. nubilipennis (Figs. 1-4, photographs and
drawings to same scale from similar sized individuals). This is difficult
to compare without having representatives of both species, but valvula 3
(sheath) of R. nubilipennis is about 1 .4 times the length of valvi fer 2 (basal
plate). Valvula 3 of R. zigadenusae is only slightly longer than the length of
valvifer 2. The ovipositor of R. zigadenusae is much shorter than that of/?.
nubilipennis, the former having about 10 serrulae, the latter about 14
(Figs. 1, 2, 5, 6, photographs and drawings to same scale from similar
sized individuals). The serrulae of each species are very similar. The
male is somewhat more difficult to differentiate, and the only differences
noted are in the genitalia. The harpe of/?, zigadenusae has a more distinct
indentation on its inner margin, the apex of the parapenis is somewhat
flatter, and the penis valve is somewhat broader apically than in R.

nubilipennis (compare Figs. 7, 8).

The specific name is based on the host plant genus.

Hosts and biological notes

Rhadinoceraea nubilipennis occurs only in the northeastern U.S. and
southeastern Canada, south in the Appalachians to North Carolina. Its
host, Veratrum virideAit. is a northern plant and is found mostly at higher
elevations further south. Zigadenus densus and Z. leimanthoides occur in
bogs, flatwoods and mesic savanna primarily on the lower coastal plain
from Louisiana east through Florida, and from southern peninsular
Florida north through New Jersey. Disjunct populations are isolated in
central Tennessee and the mountains of North Carolina and West Vir-
ginia. The junior author has collected larvae of R. zigadenusae on the
coastal plain from Mississippi to South Carolina and from the disjunct
host populations in North Carolina and West Virginia. Host pop-
ulations in the Applachicola basin of Florida and surrounding vicinity

were surveyed for two years without producing any evidence of sawflies.
Peninsular Florida populations and those from North Carolina north to
Delaware were not surveyed. Adult sawflies were collected only in
Mississippi.

Nothing is known about the life history of/?, nubilipennis except for
its host. However, a related species, /?.fl/Jnc/7/(MacGillivray) in western
North America, oviposits in and feeds on the foliage of Veratrum spp.
This is very different from the habits of/?, zigadenusae which oviposits in
the inflorescence stalk and feeds on the developing stamens and pistils
or open flowers of Zigdenus.

In southern Mississippi, R. zigadenusae emerged and flew in the sp-
ring, usually from late April to early May, which coincided with the
period when the host plant was just beginning to flower. Females ovi-
posited a single egg by inserting the ovipositor into subdermal and corti-
cal plant tissues on the primary inflorescence stalk. Of 20 ovipositing
females observed, all deposited one egg per plant visit and then flew to
another plant. The position and number of eggs was identifiable by a
nodule of swollen plant tissue. In Mississippi, 14 eggs was the maximum
number observed on a single plant. Larvae hatched within 5 to 10 days
and emerged by boring a small exit hole in the stalk. Young larvae
typically moved up the inflorescence and entered a flower bud where
they fed on the developing stamens and pistils. Older larve consumed
open flowers, and secondarily fed on fruits. When all flowers were con-
sumed, larvae ate the dermal tissue of the inflorescence stalk before dis-
persing. In plant populations where the period of ovipositing and hatching
occurred before the inflorescence was fully developed, larvae consumed
unopened flowers as well as most of the inflorescence stem. As a last
resort, larvae would attempt to feed on basal leaves, but less than 1% of all
observed infested plants displayed leaf damage and less than 5% of the
leaf area was damaged. When mature, in mid to late May on the coastal
plain, larvae burrowed shallowly into soil to pupate. Only one genera-
tion was produced each year.

Although larvae did not defoliate host plants or cause plant mor-
tality, floral herbivory caused a direct reduction in plant fecundity. Saw-
fly larvae were observed in 12 of 17 host plant populations in southern
Mississippi and literally all flowers were consumed in the majority of
these host populations. Zigadenus densus and Z. leimanthoides often
occur in the same habitat on the coastal plain with the sympatric Z.
glaberrimus Michx. However, sawflies did not utilize Z. glaberrimus as a
host. The flowering interval between the host species and Z. glaberrimus
is about three months.

Rhadinoceraea zigadenusae cannot be described as a monophagous
tloral herbivore since two host species are known, but the taxonomic dis-

18 ENTOMOLOGICAL NEWS

tinction between Zigadenus densus and Z. leimanthoides has recently
been questioned (McDearman, 1984). The nature of character differen-
tiation among these two species as well as whether Z. leimanthoides
should be reduced to an infraspecific taxon or treated as a synonym is the
subject of ongoing research. Nevertheless, the ecological specialization
of R. zigadenusae is much more restricted than the current host plant
nomenclature may suggest.

The alkaloids of the plant tribe Veratrae, which includes Zigadenus,
Veratrum, and four other genera, are the subject of an extensive literature
(e.g., Kupchan eta!., 1961; Tomko and Voticky, 1973). These compounds,
commonly known as the "veratrum" akaloids, can physiologically act as
neurotoxins (Narahashi, 1975; Jones et al., 1970), as teratogens (Van
Kampen era/., 1969; Keeler, 1971), and as vaso-dilators (Anon, 1975; Page
and Sidd, 1973). Crosby (1971) has reviewed the extremely poisonous
group of ester-alkaloids, their toxicity to a wide variety of insects, and the
history of their agricultural applications.

Considering the ecological implications of veratrum alkaloid research
as well as the role of defensive alkaloids in other plants (Levin, 1976;
Miller and Feeny, 1983; Zuniga et al., 1985) it is remarkable that only a
few of the 64 species of the Veratrae have been reported as hosts to her-
bivorous insects. Moreover, the known herbivores in North America
consist of four species of Rhadinoceraea. The Veratrae-Rhadinoceraea
( Veratra) association suggests that the distinctive alkaloid phytochemis-
try may be involved with sawfly speciation in Rhadinoceraea. Future
studies are planned by the junior author to address fundamental ques-
tions regarding host plant phytochemistry.

vector of Lyme disease. Nymphs of this species were uninvited guests at the AES Insect
Field Day in the New Jersey Pine Barrens last June. A number of participants were
unknowing hosts, although none developed the annular rash associated with Lyme di-
sease. Dr. Frank cautioned that entomologists, who are frequently in the field, are more
likely to contract the disease than the general public and should be aware of the prevention,
recognition and treatment of the disease. He distributed copies of a recent review on Lyme

A NEW SPECIES OF CURTARA (HOMOPTERA:
CICADELLIDAE) FROM BERMUDA 1.2

Paul H. Freytag^

ABSTRACT: A new species of gyponine leafhopper, Curtara bermudensis, is described
from Bermuda and compared with closely related species. This is the first gyponine known
from these islands.

A new species ofCurtara from Bermuda was sent to me for identifica-
tion, and is described at this time and compared with the closely related
species. I wish to thank M. R. Wilson, CAB International Institute of
Entomology, London, for making this series available. This species
belongs in the subgenus Curtara.

The Genus Curtara was described by DeLong and Freytag (1972),
with 76 species included (1976). DeLong and others (DeLong 1977, 1979,
1980, 1983; DeLong and Foster 1982; Delong and Triplehorn 1978, 1979;
and DeLong and Wolda 1978, 1982, 1984) have added an additional 67
species. This new species makes a total of 144 species known for this
genus.

Curtara bermudensis n. sp.

(Figures 1-5)

Length of males 6.4-6.8 mm., females 7.8-8.6 mm. Crown broadly rounded, twice as wide
between eyes at base as median length, margin foliaceous.

Color: Males brown with many dark brown spots on head and pronotum. Wings dark
brown spotted with lighter brown. Females yellow brown with few spots of darker brown on
head, pronotum and forewings.

Male genitalia: Pygofer bluntly pointed at apex. Plate four times as long as wide, trun-
cate at apex. Style broad at base, narrowed to hatchet-shaped apex, ventral margin finely
serrate. Aedeagus with shaft long, tubular, with pair of processes extending along shaft
about half length of shaft, then curving dorsad; paraphysis broadened near middle, with
dorsally hooked apex.

SPIDER (ARANEAE) TAXA ASSOCIATED WITH

THE IMMATURE STAGES OF MANTISPA
INTERRUPTA (NEUROPTERA: MANTIS PI DAE) 1 ' 2

Kevin M. Hoffman , Jeffrey R. Brushwein

ABSTRACT: The immature stages ofMantispa interrupta are associated with 10 species of
spiders, not previously recorded as hosts, from the families Gnaphosidae, Lycosidae,
Ctenidae, and Pisauridae. First-instar mantispids were found on adult and juvenile spiders of
both genders, while later-instar mantispids were located inside spider egg sacs. Larvae on
spiders were located on the edge of the carapace, on the dorsal, ventral, and lateral surfaces
of the pedicel, and inside book lungs. The locations on spiders occupied by M. interrupta
first instars are compared with those occupied by first instars of other mantispine species.

Adult Mantispinae have been reared exclusively from spider egg sacs
(Redborg and MacLeod 1985, Brushwein 1986, Hoffman and Brushwein
1989). Mantispine larvae develop through three instars by feeding on
spider eggs. Pupation occurs within the egg sac and pharate adults exit
both their own cocoons and the spider egg sacs before adult eclosion
occurs. First instars procure spider eggs either by locating and entering
preexisting egg sacs or by locating and boarding female spiders and sub-
sequently entering egg sacs as they are deposited by the spiders. Recent
studies on the spiders associated with particular mantispine species sug-
gest that these associations may be indicative of the egg procurement
methods used by first instars of those mantispine species (Redborg and
MacLeod 1985, Hoffman and Brushwein 1989).

Mantispa interrupta Say has been recorded throughout the eastern
United States and westward into Texas and Arizona (Throne 1972), and
adults have been reared from the egg sacs of three spider species. Smith
( 1 934) reported the emergence of two pupae from two spider egg sacs, one
of which was associated with a female Eris militaris (Hentz) [as Philaeus
militaris (Hentz)]. Subsequently, adult emergence has been reported
from egg sacs of Gnaphosa muscorum (L. Koch) and Lycosa rabida
Walckenaer (Kaston 1940, Rice 1985). In addition to the above records,
M. interrupta has been incorrectly reported as being associated with two
other spider species, but both associations were actually based on species
other than M. interrupta. Eason et al. (1967) associated M. intermpta with
Philodromus aureolus (Clerck) and attributed the association to Auten

(1925). However, Auten (1925) reported on the chrysopid Chrysopa inter-
rupta Schneider, notM. interrupta. Killebrew(1982) reported that a man-
tispid which emerged from an egg sac of Peucetia viridam (Hentz) was
possibly M. interrupta. However, this specimen was recently examined by
one of us (KMH) and proved to be a pharate adult of Mantispa sayi
Banks.

Viets ( 194 1 ) supplied the only indication that M. interrupta larvae can
board spiders in order to procure eggs. The laboratory boarding of an
unidentified female lycosid by several first instars was followed by
deposition of an egg sac by the spider and subsequent emergence of an
adult mantispid. Both Redborg and MacLeod (1985) and Brushwein
(1986) reported that M. interrupta has been reared using techniques
developed for two other mantispine species, but no information on
spider associations or boarding was supplied. The present paper reports
further spider associations for M. interrupta, confirms larval boarding
behavior in the field by documenting the presence of larvae on collected
spiders, and compares the locations on spiders of M. interrupta larvae
with those reported for other mantispine species.

METHODS

Eight of the 13 spiders associated with M. interrupta were collected in
pitfall traps from 12 June to 1 August 1988, four were collected by visual
searching, and the remaining association was based on museum speci-
mens. The pitfall traps were located in the Clemson University Experi-
mental Forest surrounding Lake Issaqueena, Pickens County, South
Carolina. The traps were constructed of 2 or 3 liter soft drink bottles
whose tops were cut off and inverted to form funnels. Holes were
punched in the bottoms to aid in water drainage and a few curled leaves
were supplied in each trap to provide harborage sites for trapped spiders.
Forty-four traps were buried to ground level at six locations within a
mixed hardwood-pine forest and checked one to three times each week.
The female Schizocosa saltatrix (Hentz) and egg sac were collected in the
vicinity of Lake Issaqueena on 14 May 1988, while the specimens of
Gladicosa gulosa (Walckenaer) and Varacosa avara (Keyserling) were
collected on 24 July 1988 along a tributary of Toxaway Creek at County
Road 88, Oconee County, South Carolina. The female Pisaurina brevipes
(Emerton) and egg sac were collected on 15 November 1988 near Cork-
screw, Lee County, Florida. The association of M interrupta with Sosip-
pusfloridanus Simon was based on specimens located in the entomo-
logical collections of the Museum of Comparative Zoology (MCZ), Har-
vard University. The spider and its egg sac had been collected by P. J.

Vol. 101, No. 1, January & February 1990 25

Cone in Collier County, Florida, at the junction of 840A and 846, approx-
imately 5 miles east of Immokalee. The pharate adult emerged on 16
April 1968, but collection date of the egg sac was unrecorded.

Identities of the immature stages of M. interrupta were confirmed by
comparisons of first instars with those previously obtained from an adult
female and by allowing later instars to complete development within the
egg sacs in which they were found. Spider egg sacs were identified by
determination of the particular female spider accompanying each sac.
The specimen of V. avara was reared to maturity in order to facilitate a
species-level identification. Spiders were identified both by the use of
selected taxonomic references (Brady 1962, 1979, Carico 1972, Platnick
and Shadab 1975, Dondale and Redner 1978, Peck 1981, Roth 1985) and
with the assistance of A. R. Brady and C. D. Dondale. Voucher speci-
mens of M. interrupta first instars, adults, and associated spiders are
deposited in the Clemson University Arthropod Collection (CUAC),
Department of Entomology.

RESULTS AND DISCUSSION

Eighteen M. interrupta immatures were associated with 13 spiders
representing ten spider species from the Gnaphosidae, Lycosidae,
Ctenidae, and Pisauridae, thereby bringing the total spider taxa associ-
ated with M. interrupta to 13 species in nine genera from five families
(Table 1). These species are predominantly ground-wandering hunters,
although both P. brevipes and E. tnilitaris are somewhat more arboreal
wanderers than the others and S. floridanus builds funnel webs near
ground level.

First instars of M interrupta were associated with adult and juvenile
spiders of both genders, whereas later instars were found inside spider
egg sacs (Table 1). The locations of first instars aboard spiders included
the edge of the carapace, the dorsal, ventral, and lateral surfaces of the
pedicel, and the book lungs. Two of the nine spiders boarded by first
instars had more than one larva. Larvae on these spiders occupied either
different regions of the same structure, e.g., opposite sides of a pedicel, or
similar regions of separate structures, e.g., the left and right book lungs.
Two first instars were dead when collected; one was found in a book lung
along with a live larva and the other was alone in the book lung of a dif-
ferent spider. In the only previous report of M. interrupta first instars
aboard a spider, Viets ( 1941 ) noted that larvae crawled over the body of
the spider upon boarding and that the area between and around the
spinnerets seemed to be preferred. However, the positions of the several
larvae which remained on the spider after 15 days was not mentioned,
and it is possible that some larvae resided in locations similar to those

reported above. The presence of first-instar M. interrnpta on spiders,
coupled with the predominantly wandering-mode behavior of the as-
sociated spiders, supports the hypothesis of Hoffman and Brushwein
(1989) that mantispine species which use spider boarding to gain access
to spider eggs will be associated generally with wandering spiders.

Of the four other mantispine species known to board spiders, only
first instars of M. sayi [as Mantispa uhleri Banks and Mantispa fuscicornis
Banks, both recently synonymized with M. sayi by Hoffman (1989)]
occupy a range of resting sites on spiders similar to that of M interrupta
first instars (Redborg and MacLeod 1985, Rice 1986). In contrast, first
instars of the other three species occupy a more restricted range of sites.
First instars of Climaciella brunnea (Say) have been found only on the
sternum and the edge of the carapace (Redborg and MacLeod 1983,
LaSalle 1986), while those of both Perlamantispa perla (Pallas) and Man-
tispa pulchella (Banks) occupy only the dorsal surface of the pedicel
(Lucchese 1955, 1956, Hoffman and Brushwein 1989).

In previous reports of M interrupta spider associations, the develop-
mental stages of the mantispids at the time of egg sac collection were not
known. However, some estimates can now be made by comparing the
intervals between egg sac collections and emergences of adult mantis-
pids with the durations of appropriate developmental stages of M inter-
rupta and other North American mantispines. During the present study,
the two M. interrupta which were reared under ambient conditions from
third instars to adult required 17 to 22 days from the onset of cocoon
spinning to adult eclosion. Under standard laboratory conditions. C.
brunnea, M. sayi, and Mantispa viridis Walker spend an average of 14 to 20
days as prepupae and pupae (Redborg and MacLeod 1983, 1985, Brush-
wein 1986). Both Smith (1934) and Rice (1985) reported the emergences
of adult mantispids within four days of egg sac collections, and therefore
these records surely represent field-collected pupae and are listed as
such in Table 1. Because of the 17 day lag between egg sac collection and
adult emergence, the mantispid collected by Kaston (1940) could have
been either a late-instar larva or pupa. Unfortunately, the collection date
of the S.floridanus egg sac was unrecorded, and therefore the develop-
mental stage of the mantispid when initially collected can not be deter-
mined.

THE RELATION BETWEEN HEARING
AND FLYING IN CRICKETS 1

Daniel Otte 2

ABSTRACT: Hearing and flying are closely coupled functions in true crickets (Gryl-
loidea). Although the auditory tympana have been lost many times independently in cric-
kets, they are virtually never lost in species that can fly. Since crickets migrate at night it
seems likely that tympana are retained to avoid bat predation.

The ancestor to modern crickets (Grylloidea) probably possessed
tibial auditory tympana and tegminal stridulatory devices similar to
those of modern species. Subsequently the stridulum (and therefore
acoustical communication) has been lost many times. In Australia, for
example, where 103 species (or 18.9% of the known fauna) lack a stri-
dulum, the stridulum was lost at least 27 times. In Africa it was lost at
least 17 times. It was lost a number of times on Pacific islands as well (i.e.
New Caledonia, Hawaii, Fiji, and Lord Howe Otte, Alexander and
Cade 1988, Otte and Rentz 1985, Otte and Rice in prep.)

Although the stridulum has not been lost in any United States species,
calling behavior has been lost in at least seven species (Gryllus ovisopis
[Gryllinae], Oligocanthropus prograptus [Mogoplistinae], Tafalisca lurida
and Hapithus brevepennis [Eneopterinae], Falcicula hebardi [Trigoni-
diinae], Scapteriscus abbreviates [Gryllotalpinae] and northern pop-
ulations of Hapith us agitator [Eneopterniae]) (Walker 1974). Absence of a
calling song must be a precurser to the loss of the stridulum; therefore
examination of these species should give one clues as to the selective forces
causing muteness and deafness.

Walker (1974) notes also that Gryllus fultoni on Key Largo lacks a
functional calling song. And in the sibling pair Hapith usmelodius and//.
brevipennis, the former species retains both calling and courtship songs,
while the latter has never been heard to produce either song, even though
it appears to have a functional stridulum.

The circumstances which cause non-acoustical methods of com-
munication to entirely replace acoustical modes is open to speculation.
Do acoustical signals lose their directionality, and therefore effective-
ness, in certain situations (caves, burrows), or become ineffective in the
presence of noise (sea shores), or less effective than other modes of signal
transmission (pheromones, substrate vibration, visual signals) under
certain circumstances (burrows, caves, or on grasses)?

Walker (1974), noting that all U.S. mute species are flightless, specu-
lates that muteness is associated with their higher degree of sedentari-
ness: "Sedentary populations characteristically occupy relatively per-
manent habitats and are not subject to the extreme fluctuations in den-
sity of breeding adults characteristic of temporary habitats. Consequen-
tly, chance encounters or short-range signals become more dependable
pair-forming techniques." He suggests two other possible causes: acous-
tically orienting predators could select against singing males; or the loss
of song could evolve if it caused reduction in interbreeding with a closely
related species possessing a nearly identical song (as may have hap-
pened to Gryllus ovisopis when it speciated from G.fultoni).

In Australia mute species are best represented among the following
groups: a) burrowing crickets from rain-forests and open woodlands
(most belong to the genus Apterogryllus [Brachytrupinae] and all pro-
bably derive from a single mute and wingless ancestor); b) crickets
inhabiting lush grasses along water courses (all are small Trigonidiinae,
but the stridulum may have been lost 3 or 4 times in this group); c) cric-
kets inhabiting canopy foliage in rain forest or seasonally wet woodland
(these belong to three groups: Trigonidiinae (Amusurgus, Metiochodes,
Cyrtoxiphoides); Podoscirtinae (Mundeicus, Aphonoides); and Pentacen-
trinae; d) crickets inhabiting seasonally moist grasslands (Euscyrtinae
probably lost at least twice); e) crickets inhabiting ant nests (Myr-
mecophilinae muteness probably evolved but once in this group,
perhaps outside Australia); forest floor (leaf litter) species (Nemo-
biinae and Phalangopsinae stridulum perhaps lost three times in the
Nemobiinae and two or three times in the Phalangopsinae); g) shore-
inhabiting species (Nemobiinae, Apternonemobius since this genus is
widespread over the Pacific ocean, the stridulum may have been lost out-
side Australia; (h) cave-inhabiting species (Nemobiinae, Nambungia}.

A survey of the Australian crickets shows that auditory tympana are
often retained after the tegminal stridulatory mechanism is lost, that is,
they continue to hear after becoming mute (Amusurgus, Metiochodes
[Trigonidiinae] Pentacentrus [Pentacentrinae] Mundeicus, Umbulgaria,
Aphonoides, [Podoscirtinae], Euscyrtus, and Patiscus [Euscyrtinae]. Par-
tial loss of the stridulum is seen in Hemiphonus, Unka (Podoscirtinae),
Trigonidomorpha (Trigonidiinae) and Merrinella (Euscyrtinae). Since a
loss of the sound producing mechanism is probably usually accom-
panied (or followed) by a loss in the listening mechanism, one must pre-
sume that some kind of selection pressure opposes the loss of a tympanum
in these species.

In my survey of the Australian fauna (based on Otte and Alexander
1983) I noticed that virtually all flying species retain a tympanum, even
those species that have lost the stridulum. The only non-hearing crickets

Vol. 101, No. 1, January & February 1990 31

are ones that cannot fly. We can look at the relation between singing:',
hearing 4 , and flying 5 in the Australian fauna more closely. All the possi-
ble combinations of these three characters are shown in Figure 1 and
next to them the number and the percentage of species possessing the
condition. Two very common conditions occur in this fauna: A large
number of species can sing, hear, and fly. But a much larger number of
species can sing and hear, and are flightless (B). Of the remainder, 57
species (or 20% of the total) cannot fly, cannot hear and cannot sing (H);
46 species (10%) cannot sing but can both fly and hear (D). Notice that
two of the possible combinations have no representative species: There
are no species which can sing and fly but cannot hear (C) and there are
no mute and deaf species which can fly (G). Condition C may be absent
for two reasons: a) Perhaps a species which cannot hear will not retain its
song mechanism. This is probably true in most cases, but rare instances
do occur in which males continue to sing even though a stridulum is lost
(as in condition F Evans 1988). b) The condition is rare because flying
species are selected against if they are deaf. The latter reason is probably
true, given that there are no species which can fly and which cannot also
hear (see also condition G).

Few species have conditions E and F; both conditions are probably
transitional between B and H. Outside Australia I know of no species
with either of these conditions. Of the four Australian species which
have lost the stridulum but retain the tympanum, one species has a tiny,
apparently rudimentary, organ; another species is geographically vari-
able with western Australian specimens retaining a tympanum, and eas-
tern Australian ones having lost it (perhaps in this species occasional
individuals are macropterous).

Condition F, in which the stridulum is retained in a species that has
lost its tympana, is also exceptional. Fortunately the acoustical behavior
of one of these species is known. Males ofBalamarogidya have a peculiar
mode of signalling (Evans 1988). In the presence of females they tap the
grass on which they rest with the abdomen, presumably transmitting
information to the females through vibration of the subtrate. Males tap
in pairs, and during the first tap of each pair they stridulate. We do not
know what B. gidyas nearest relatives do. B. marroo possesses both a
stridulum and well-developed tympana. B. albovittata from eastern Aus-
tralia has no stridulum and no tympana; in western Australia this species
has no stridulum but retains a small tympanum. We speculate that in the
lineage leading to B. gidya males called females by stridulating; later,
males began to vibrate the substratum (grass blades on which both were

perched) during stridulation; gradually tapping began to predominate
as the information carrier, and tympana were lost when the acoustical
component of the signal disappeared; the stridulation now heard faintly
during the first tap is perhaps a vestige of the original call. Once it disap-
pears, as it may already have done in B. albovittata, the stridulum may
also be lost.

One is led to conclude that hearing is important to flying crickets.

Figure 1 . All possible combinations of singing, hearing, and flying in the known Australian
cricket fauna. Singing means possession of a stridulatory mechanism; hearing means
possession of a tibial auditory tympanum', flying means possession of hind wings long
enough to make flight possible. Numbers in the upper right indicate the number (and per-
centage) of species possessing the condition. Arrows indicate the presumed direction of
evolutionary change. Parallel lines indicate evolutionary transformations which have pro-
bably not occurred a and b because absence of hearing in flying species is perhaps
strongly selected against by bats or other predators; c, d, e, and f because once a particular
complex mechanism is lost it is highly unlikely to evolve again. Conditions E and F are
absent in African and other faunas, suggesting that the transition from B or D to H is
rapid.

Vol. 101, No. 1, January & February 1990 33

Africa and Pacific island crickets hold to this pattern precisely, though
we have discovered a single species of Adenopterus (Loyalty Islands)
which possesses long hind wings and lacks tympana (Otte, Alexander
and Cade 1987).

The association between hearing and flying is also evident within
some Australian species which show developmental flexibility in both
characteristics further confirming a functional coupling between
them. Euscyrtus hemelytrus (Euscyrtinae) always possesses tympana, but
the outer tympanum is sometimes obsolete in micropterous specimens.
In general, macropterous individuals have larger tympana. We noted the
following variation in this species (Otte and Alexander 1983): Microp-
terous individuals are quite variable, with the outer tympanum some-
times obsolete and represented only by a dimple. Macropterous males
had very large and conspicous inner and outer tympana. A macrop-
terous male and female from Upper Burma have very large inner and
outer tympana, but a micropterous female has inner and outer tympana
barely visible. A micropterous female from Manila, Philippines has an
outer depression and a conspicuous inner tympanum. Two microp-
terous males and a female from Assam (Bangladesh) have an inner tym-
panum and the other tympanum represented by a dimple. Four other
females from the same place are macropterous and have large inner and
outer tympana.

Metioche vittaticollis (Trigonidiinae) are similar to Euscyrtus. Macrop-
terous individuals posses large tympana, while micropterous individuals
have either small inner and no outer tympana, or small outer and larger
inner tympana, or no tympana at all. Of 61 individuals examined only
the 45 macropterous individuals had prominent inner and outer tym-
pana.

We also noted dimorphism in wings and tympana in Trigonido-
morpha sjostedti (Otte and Alexander 1983). In this species wingless
males and females usually have small dimples instead of tympana:
occasionally a small inner tympanum is visibile. Evans (1988) has fur-
ther studied wing length and tympana in this species. She crossed the two
phenotypes (winged/ +tympana and wingless/ -tympana) and found
that the dimorphism does not result from a simple Mendelian 1-locus. 2-
allele mechanism, since all crosses produced both phenotypes in both
sexes. Field collected wingless/-tympana adults produced winged/
+ tympana offspring. She also found that both morphs possessed tym-
panal organs with well developed scolopidia, attachment cells, and
accessory cells, in close proximity to the anterior tympana trachea; but
the tympana of the wingless morph were hidden beneath a layer of
cuticle.

Several experimental studies have shown that crickets can hear bat
sounds and take evasive action in the presence of bat sounds (Griffin
1958, Popov and Mrkovich 1982, Moiseff and Hoy 1983, Nolen and Hoy
1984, Doherry and Hoy 1985).

It has also been suggested that the development of receptors sensitive
to aerial sounds may have been favored by selection if they enabled
individuals to stay within a dispersing group by responding to the flight
sounds of conspecifics (Evans 1988, and references therein).

THE LEPTOCERIDAE (TRICHOPTERA) OF
WEST VIRGINIA 1

James B. Glover, Donald C. Tarter 2

ABSTRACT: Over 9,000 adult leptocerids were identified from light trap samples through-
out West Virginia. A total of 27 species, including 25 new state records, are reported for West
Virginia. The most common species in the state included Cerac/ea cancellata, C. maculata.
Oecetis avara, and O. inconspicua. Species that were abundant only in the larger rivers of
the western portion of the state included C. /7ava, C. macu/afa, Nectopsyche pavida, and
Triaenodes ignitus. Cerac/ea ne/77 was most abundant in the smaller, cooler, fast-flowing
streams at the higher elevations in the eastern part of the state. Cerac/ea ophioderus (IL.
NC, SC), C. slossonae (FL, GA. PA, VA), and C. wetzeli (MI, PA) were important range
extensions into West Virginia. The collection period ranged from 30 April (O. inconspicua
and T. ignita) to 17 October (O. c/nerascens).

Prior to this study, only two species ofleptocerids had been reported
from West Virginia: Oecetis avara (Banks) (Ross, 1944) and Mystacides
sepulchralis (Walker) (Yamamoto and Wiggins, 1964). Based on the
examination of 9,136 adult leptocerids from black light and Malaise
traps, 27 species, including 25 new state records, are recorded from
West Virginia.

Three important range extensions are noted: Cerac/ea ophioderus
(Ross) (IL, NC, SC); C. slossonae (Banks) (FL, GA, PA, VA); and C. wet-
zeli (Ross) (MI, PA).

The collection period ranged from 30 April, Oecetis inconspicua
(Walker) and Triaenodes ignitus (Walker), to 17 October, O. cinerascens
(Hagen). The only species that was collected exclusively in the early part
of the year (30 April- 6 June) was T. ignitus. One male of C. wetzeli was
collected on 14 May. Some species had extended flight periods begin-
ning in May and extending into September.

Detailed collecting data are found in Glover (1988). All adults are
stored in the West Virginia Benthological Survey at Marshall Univers-
ity.

SOME ECTOPARASITES OF BATS FROM
HALMAHERA ISLAND, INDONESIA 1

B.V. Peterson 2 , L.A. Durden 3 , J.E. Keirans 4 , P.M. Taylor 5

ABSTRACT: New host and distribution records are given for some ectoparasites of the
families Nycteribiidae. Streblidae, Ischnopsyllidae(Insecta).Argasidae, Laelapidae. Spin-
turnicidae and Trombiculidae (Acari) removed from eight species of bats collected on the
Indonesian island of Halmahera.

The ectoparasites upon which this report is based were collected as
part of an ethnographic field research study conducted by P.M. Taylor
among Tobelo-speaking peoples of Halmahera Island, Indonesia, from
December 1980 to November 1981, and was sponsored locally by
Khairun University, Ternate, Indonesia. The study was carried out with
the cooperation of the Indonesian Institute of Sciences, and the Indone-
sian Nature Conservancy. Biological specimens were collected through-
out the area inhabited by the Tobelo people in order to record local
information on the native classification and uses of animals and plants
and to provide material for zoological and botanical investigations
(Taylor, 1985, in press). Halmahera (sometimes referred to as "Jilolo" or
"Gilolo") is the largest island of the Moluccas. It lies on the Equator and
is situated southeast of the Philippines, west of the western tip of Irian
Jaya, and North of Seram. Knowledge of the ectoparasitic fauna of bats
from the Moluccas and surrounding territories, and especially Halma-
hera, is meager, therefore the records from this survey are valuable for
inventory purposes and also for elucidating our knowledge of host-
parasite associations in this part of the world.

MATERIALS AND METHODS

Ectoparasites taken during this study were removed from 1 55 bats of
8 species, plus 16 unidentified bats, mist-netted on the Indonesian island
of Halmahera (KampungPasirPutihJailolo District, aKraK 12741T)
by P.M. Taylor and A.C. Messer in 1981. An additional specimen of

Pteropus personatus Temminck was collected by P.M. Taylor in 1984. As
field conditions allowed, care was taken to prevent contamination of
ectoparasite collections from different host individuals. All ectopara-
sites collected were placed in 70% ethanol for later processing and iden-
tification. The bat flies and fleas are deposited in the National Museum
of Natural History, and the ticks are deposited in the U.S. National Tick
Collection, Museum Support Center, Smithsonian Institution, Wash-
ington, D.C. Bat nomenclature follows Honacki et al. (1982).

RESULTS

The bats examined for ectoparasites were as follows: Dobsonia cren-
ulata K. Anderson, Eonycteris spelaea (Dobson), Macroglossus minimus
(E. Geoffroy), Nyctimene albiventer (Gray), Pteropus conspicillatus Gould,
Pteropus personatus, Rousettus amplexicaudatus (E. Geoffroy) (family
Pteropodidae), and Rhinolophus euryotis Temminck (family Rhinolo-
phidae). Table 1 depicts the host associations and the numbers of ecto-
parasites collected in this survey. In addition, 2 1 nycteribiids, 2 streblids,
208 larval ticks, and a mixture of 13 nymphal and adult spinturnicid
mites were removed from 16 bat specimens from which the identification
labels became detached. These ectoparasites could not be matched with
individual bat species (see Table 1).

DISCUSSION

Of the 1 1 species of bat flies collected during this survey (7 nyc-
teribiids^ streblids) the following represent new records for Halmahera:
Archinycteribia actena Speiser, Eucampsipoda inermis Theodor, Cyclo-
podia albertisii Rondani, Leptocyclopodia (Oncoposthia) macrura (Speiser),
Phthiridium phthisicum (Speiser) (Nycteribiidae), and Megastrebla
(Megastrebla} gigantea (Speiser), M. parvior Maa, and Raymondia pseu-
dopagodarum Jobling (Streblidae). Two species, Cyclopodia species B
(Nycteribiidae) and Brachytarsina species A (Streblidae), apparently are
undescribed but cannot be treated further until specimens of previously
described, related species are obtained for comparative purposes. The
ischnopsyllid flea, Thaumapsylla longiforceps Traub, and the laelapid
mite, Neolaelaps spinosa (Berlese), are also new records for Halmahera.

Nycteribiidae

Archinycteribia actena has been recorded from Sulawesi (Celebes)
and Seram east to the Solomon Islands and Australia (Maa, 1962, 1971;
Theodor, 1967, 1968; Durden et al., 1990). In the present survey it was

Vol. 101, No. 1, January & February 1990 41

collected from 3 hosts (Table 1 ), always in association with Cyclopedia
tennis and either Eucampsipoda inermis or Megastrebla (M.) gigantea.
Species of Dobsonia Palmer serve as primary hosts of Archinycteribia
actena throughout the range of this fly with D. crenulata the primary host
on Halmahera.

Our specimens of Eucampsipoda inermis from Halmahera apparently
constitute the first record of the genus from the Molucca Islands. This
species has been reported from Burma, Thailand, Malaya, Java, Sumba,
the Philippines, and Papua New Guinea (Theodor, 1955, 1963, 1967,
1968; Maa, 1962, 1977). Its primary hosts are Rousettus amplexicaudatus
and Eonycterisspelaea. On Halmahera the species also occurred primarily
on these 2 hosts; however, a few specimens were collected from Dobsonia
and Macroglossus. The records, other than those from the 2 primary host
species, probably represent accidental occurrences.

Cyclopodia tennis is known from Malaya, Java, Borneo and the
Moluccas (Theodor, 1959, 1967; Maa, 1966, 1977). It was first reported
from Halmahera by Theodor (1959) from Macroglossus minimus. Maa
(1966) stated that Theodor's record of a single female from Halmahera
needed confirmation. We are now able to verify this distribution record.
This was the second most common species in our collection. On Halma-
hera, Cyclopodia tennis was found almost entirely on Macroglossus min-
imus (originally identified as M. lagochilus but Honacki et al. (1982) list
lagochilus as a synonym of minimus). This parasitic fly was taken once
from Rousettus amplexicaudatus, once from Eonycteris spelaea, and once
from Nyctimene albiventer. The latter 3 host records probably represent
accidental occurrences.

Cyclopodia albertisii is known from the Moluccas (Goram), Belau
(Palau) Islands. Papua NewGuinea, and Australia (Theodor. 1959, 1967;
Maa. 1962, 1971). Our collection from Halmahera contains 9 specimens
all from a single host specimen of Pteropus conspicillatus. There were no
other associated ectoparasites on this host specimen.

Twenty-two specimens of Cyclopodia species B were taken from 4
specimens of Pteropus personatus. This fly probably is undescribed even
though it runs to Cyclopodia bougainvillensis Theodor in Theodor's 1967
keys. There are some differences between features in Theodor's descrip-
tion and those of our specimens but. until comparative material ot
bougainvillensis becomes available, it is impossible to be sure of the cor-
rect identity of our specimens.

Thirteen specimens of Leptocyclopodia (O.) macrura were removed
from 10 specimens of Dobsonia crenulata, and another male was found
on 1 unidentified bat. In addition to the range previously recorded for
this distinctive species (Durden, et al.. 1990), we now add Halmahera.
Associated species are listed in Table 1.

42 ENTOMOLOGICAL NEWS

Three individual specimens of Phthiridium phthisicum were collected
from 3 separate individuals of Rhinolophus euryotis, and always in as-
sociation with at least 1 other species, Raymondia pseudopagodarum or
Brachytarsina species A. The female of Phthiridium phthisicum was ori-
ginally described from Rhinolophus euryotis, from Amboina (Speiser,
1907). The male was later described from a specimen from Seram taken
from an unidentified species of Rhinolophus Lacepede, ". . . which ac-
cording to the form of the thorax and other characters resembles the
female closely [and] is considered to belong to this species." (Theodor,
1 968). The identity of our female specimen is reasonably certain, but that
of our 2 males is less certain. Our males do not completely coincide with
Theodor's description or match his figures. It is possible that our, or
Theodor' s association of the sexes is wrong. Only when both sexes from a
single host individual are available can a decision be made. Our speci-
mens might be one of several subspecies mentioned by Maa ( 1986) but,
again, comparative material is needed to be sure.

Streblidae.

Megastrebla (M.)gigantea is a widespread bat fly (Durden et al., 1990).
Seven specimens were collected from 3 species of bats and always in
association with 1 to 3 species of Nycteribiidae (Table 1).

A single female of Megastrebla (M.)parvior was taken from an Eonyc-
teris spelaea in association with Eucampsipoda inermis and Cyclopedia
tenuis.

Five specimens of RaBrachytarsina (here referred to as species A)
were collected from Rhinolophus euryotis. This fly closely resembles
Brachytarsina modesta Jobling and B. trinotata Maa, but comparative
material is not available to help confirm its identity.

Two males and 2 females of an apparently undescribed species of
Brachytarsina (here referred to as species A) were collected from Rhino-
lophus euryotis. This fly closely resembles Brachytarsina modesta Jobling
and B. trinotata Maa, but comparative material is not available to help
confirm its identity.

Ischnopsyllidae

Thaurnapsylla longiforceps was the only species of flea retrieved dur-
ing this survey. Although it has been collected from several unrelated bat
hosts (Hopkins and Rothschild, 1956), it appears to show a preference
for various species of the genus Rousettus( Holland, 1969). In Java, Hadi
et al. (1983) recorded 'Thaurnapsylla sp/ from Rousettus leschenaulti (Des-
marest) and Eonycteris spelaea', the latter was the only host species from
which T. longiforceps was recovered in this survey. Thaumapsylla longifor-

Vol. 101, No. 1, January & February 1990 43

ceps has been reported from Java, Borneo and the Philippines southeast
to New Guinea (Hopkins and Rothschild, 1956). In addition, we have
seen 1 19 specimens from 21 previously unreported collections of T. lon-
giforceps, all identified by R. Traub (pers. comm.): 73 specimens from
Rousettus amplexicaudatus (Sumatra (8), the Philippines (41), Sulawesi
(2),Flores (7) and Timor ( 1 5) ); 2 specimens from Rousettus sp. (the Philip-
pines); 3 specimens from Cynoptems brachyotis (Muller) (Sumatra (2) and
Java (1); 1 specimen from Eonycteris major (K. Anderson) (the Philip-
pines); and 40 specimens from unidentified bats (the Philippines (39)
and New Guinea (1)).

Argasidae

All ticks collected were larvae belonging to the genus Ornithodoros
Koch, subgenus Reticulinasus Schulze. All known species of this sub-
genus parasitize cave-dwelling megachiropteran bats (Dumbleton,
1958; Hoogstraal, 1962; Hoogstraal and Aeschlimann, 1982). Species of
Ornithodoros (Reticulinasus} are known from the Near East, Africa and
Madagascar eastward to India, Indo-Australia and the Solomon islands
(Dumbleton, 1958; Wirorenoe/ar/., 1979; Hoogstraal and Aeschlimann.
1982). The ticks collected from Halmahera represent 3 undescribed
species: most specimens belong to the species here designated as species
# 1 , but 1 specimen removed from Dobsonia crenulata belongs to a second
species (species #2), and 10 taken from an individual Rousettus amplex-
icaudatus include specimens of species # 1 and examples of a third taxon,
species #3. It is hoped that future collecting on Halmahera will produce
postlarval specimens of these 3 undescribed ticks.

Laelapidae

Neolaelaps spinosa was the only laelapid mite collected in this survey.
It occurred in low numbers on both Dobsonia crenulata and Pteropusper-
sonatus. This mite typically parasitizes several species ofPteropus and is
known from Sri Lanka eastward through Indo-Australia to New Ireland
(Strandtmann and Garrett, 1967). Our record from Dobsonia crenulata is
considered to represent an accidental infestation.

Spinturnicidae and Trombiculidae

The remainder of the ectoparasites collected in this survey consisted
of an estimated 6 to 9 species of spinturnicid mites, and 2 species of larval
chigger mites (Trombiculidae). The host associations of these two families
are shown in Table 1. Both mite groups are frequent ectoparasites of
pteropodid bats, particularly in Indo-Australia (Beck, 1971; Hadi et al..

forDobsonia crenulata with all but 2 of the 76 specimens collected being
taken from this host. Spinturnicid mites were common on D. crenulata,
Eonycteris spelaea and Rousettus amplexicaudatus, and scarce on Mac-
roglossus minimus; none were taken from the other 4 bat species exam-
ined in this survey.

SOME ECTOPARASITES OF BATS FROM
SERAM ISLAND, INDONESIA 1

L.A. Durden 2 , B.V. Peterson 3 , N. Wilson 4 , B. Christiansen 5

ABSTRACT: New host and distribution records are provided for some ectoparasites of the
families Streblidae, Nycteribiidae, Ischnopsyllidae (Insecta), Ixodidae, Argasidae, Lae-
lapidae, Spinturnicidae and Macronyssidae (Acari) removed from 9 species of bats collect-
ed in Manusela National Park, on the island of Seram, Indonesia.

The Indonesian island of Seram (Ceram) is situated in the Moluccan
Archipelago between Sulawesi and Irian Jaya. Zoogeographically, it is
part of the Wallacean subregion (the faunal transition zone between
Asia and Australasia) and while part of the terrestrial fauna is endemic,
much of it extends to the east and west in varying degrees. No endemic
species of bats are known from Seram and this fauna shows Asian, Aus-
tralasian, Malesian (Melesia: the biogeographical region stretching
from Sumatra and the Malay Peninsula east to the Bismarck Archi-
pelago (Whitmore, 1981, 1987)) or Moluccan distributions. Bat ecto-
parasite records from Seram are few and therefore valuable not only for
inventory purposes but also for elucidation of host-parasite associations.

MATERIALS AND METHODS

Ectoparasites were collected by visual searches from 36 bats of 9
species mist-netted in Manusela National Park, Seram (3 15'S, 12938'E),
during July and August, 1987. Ectoparasite material was stored in 70%
ethanol until it could be processed for identification.

RESULTS AND DISCUSSION

The 9 bat species collected and the numbers of each examined for
ectoparasites were as follows (bat nomenclature follows Honacki et al.,
1982): Dobsonia viridis (Huede) (Icf, 1699), D. moluccensis (Quoy and
Gaimard) (Icf, 19), Rousettus amplexicaudatus ( E. Geoffrey) (2c?cf, 599),

Syconycteris australis (Peters) ( 1 cf , 19), Pteropus temmincki Peters (1 cf , 1 Q )
(family Pteropodidae), Miniopterus australis Tomes (2cfcf) (family Ves-
pertilionidae), Rhinolophus euryotis Temminck (Icf) (family Rhinolo-
phidae), Chaerephon jobensis (Miller) (19), and Mormopterus beccarii
Peters (299) (family Molossidae).

Table I lists the ectoparasites collected during this survey. The bat
flies and the single flea are deposited in the U.S. National Museum of
Natural History, Washington, D.C., and the ticks are in the U.S.
National Tick Collection, Smithsonian Institution, Washington, D.C.
(accessioned under RML 1 19,061-1 19,075).

The ectoparasites recorded here from Seram bats are fairly typical for
this group of hosts. The following species represent new records for
Seram: Brachytarsina (Brachytarsina} amboinensis Rondani, Megastrebla
(Magastrebla) gigantea (Speiser), M. (M.)pan'ior (Maa), Raymondia pseu-
dopagodarum Jobling (Streblidae); Archinycteribia actena Speiser, Nyc-
teribia parilis Walker (Nycteribiidae); Thaumapsylla breviceps Rothschild
(Ischnopsyllidae), and all of the ticks and mites.

Most of the bats and ectoparasites retrieved during this survey are
known to have wide but contrasting geographical distributions. With
respect to the streblid bat flies, Brachytarsina (B.) amboinensis was only
taken from Miniopterus australis which ranges from India to China
(Hainan) and northeastern Australia. The known range of Brachytarsina
(B.) amboinensis is similar extending from India and Sri Lanka east to
Australia, Vanuatu and New Caledonia (Jobling, 1951; Hiregaudar and
Bal, 1956; Maa, 1962, 197 la, 1977; Maa and Marshall, 1981). This bat fly
is represented by several subspecies in various parts of its range, and
specimens from Seram appear to belong to the nominate subspecies.
Brachytarsina (B.) amboinensis is principally parasitic on various species
of Miniopterus Bonaparte.

The streblid, Megastrebla (M.) gigantea was collected from both
species of Dobsonia Palmer. Dobsonia viridis is distributed throughout the
Moluccan and Banda Islands and the Philippine island of Negros while
D. moluccensis extends from the Moluccas eastward to Aru, New Guinea,
and northern Queensland. Megastrebla (M.) gigantea has been recorded
from India east to New Britain (Jobling, 1951; Hiregaudar and Bal, 1956;
Maa, 1962). However, Maa (1971 b) later stated that this species with its 3
subspecies (gigantea gigantea, g. kalawawae Maa, g. solomonis Maa)
ranges only from Sumba east to the Solomon Islands, and that all other
records must be held suspect. This is the largest known species in the
genus and is probably restricted to bats of the genus Dobsonia. The
specimens from Seram are of the nominate subspecies.

Megastrebla (M.) parvior was collected from Rousettus amplex-

50 ENTOMOLOGICAL NEWS

icaudatus. This bat ranges throughout Malesia whereas Megastrebla par-
vior has a known distribution extending from India and Burma east to
the Philippines, south to Sumatra, Sumba and New Guinea (Maa, 1962,
197 Ib, 1977). The specimens from Seram are of the nominate subspecies.
Maa (1962) recorded the Sumba series of specimens from Rousettus
amplexicaudatus, and the remaining type series from Eonycteris spelaea
(Dobson). Rousettus Gray is the primary host of the nominate subspecies
(Maa, 1971b),but it has also been recorded from a number of other hosts.
A second subspecies, Megastrebla parvior papuae Maa, was described
from New Guinea from Rousettus amplexicaudatus and Dobsonia moluc-

censis.

Raymon dia pseu dopago daru m was removed from a male Rhinolophus

euryotis. This bat ranges from Sulawesi east to the Moluccas, Timor, New
Guinea, the Bismarck Archipelago and adjacent small islands whereas
its tiny parasite ranges from Burma, Thailand, China, east to the Philip-
pines, and south to Timor and Seram (Jobling, 1951; Maa, 1962, 1977).
Primary hosts for Raymondia pseudopagodarum seem to be species of
Rhinolophus Lacepede and Hipposideros Gray, although a few other sus-
pect hosts have been listed for the species.

With respect to the nycteribiid bat flies, Archinycteribia actena was
collected only from Dobsonia viridis. This fly has previously been record-
ed from Ambon, New Guinea, the Solomon Islands and Australia (Maa,
1962, 1971a;Theodor, 1967). In4ofthecollections,/l.tf<:'tert<7 was taken in
association with Leptocyclopodia (Oncoposthia) sp. A, once with Megas-
trebla (M.)gigantea, and twice by itself.

The single specimen of Cyclopedia sp. collected from Syconycterisaus-
tralis is in poor condition, but from the characters that can be seen it
could be Cyclopodia sycophanta Maa that parasitizes the same host, or it
might represent a new species in the C. sycophanta group. Additional
specimens will be needed before the identity of this species can be deter-
mined with certainty.

Leptocyclopodia (Oncoposthia) macrura Speiser was collected only
from Dobsonia moluccensis; this bat fly was previously reported from D.
moluccensis on the islands of Biak and Owi off the northern coast of New
Guinea (Hadi et al., 1980). Leptocyclopodia (O.) macrura is a distinctive
species and has also been recorded from Sumbawa, Ambon, Seram, New
Guinea, and New Britain (Maa, 1962, 1966, 1968, 1975; Treodor, 1959,
1967) which approximates the distribution of Dobsonia moluccensis.

Leptocyclopodia (Oncoposthia) sp. A was collected mainly from Dob-
sonia viridis although 2 specimens were taken from Syconycteris australis.
This latter bat species ranges from the Moluccas eastward to New
Guinea, the Bismarck Archipelago and adjacent small islands and
south to Australia. These bat fly specimens probably represent a new

Vol. 101, No. 1, January & February 1990 51

species since neither sex runs successfully in Maa's key (1975) nor do
they fully match the descriptions or illustrations of the other species of
this subgenus. The true status of this fly can be determined only when
comparative material of other closely related species is available.

Nycteribia parilis was found only on a male Miniopterns australis. The
same host individual yielded 8 specimens of the streblid Brachytarsina
(B.) amboinensis. Nycteribia parilis is known from Ambon, Batchian,
Timor, and other Moluccan islands. New Guinea and Australia prin-
cipally from various species of Miniopterus (Maa. 1962, 197 la; Theodor.
1967). There are 2 subspecies of this bat fly: the nonimate subspecies over
most of its range, and p. vicaria Maa from Australia.

Thaumapsylla breviceps, the only flea collected, has a very broad
geographical range that includes much of the Ethiopian and Oriental
Regions. However, 2 subspecies are known: the nominate subspecies in
Africa, and b. orientalis in Southeast Asia (Hopkins and Rothschild.
1956). Although it is most likely that the latter taxon was collected in this
survey, the 2 subspecies can only be separated by male characters and
the Seram specimen is a female. This flea typically parasitizes Rousettus
bats, which agrees with the R. amplexicaudatus record documented here
for Seram. Thaumapsylla breviceps has hyper-developed pronotal combs
that may facilitate attachment to its volant hosts and partly explain why
this species has such a large geographical distribution (Traub. pers.
comm.).

The tick, Ixodes (Eschatocephalus) simplex Neumann, occupies a vast
geographical area within the Palaearctic, Ethopian, Oriental and Aus-
tralasian Regions (Arthur, 1 956; Wilson, 1 970; Clifford et al., 1 973). It was
taken only from Miniopterus australis in this survey, an anticipated assoc-
iation since Miniopterus is the usual host (Wilson, 1970).

Ixodes (Lepixodes) kopsteini Oudemans is known to parasitize bats in
the Ethiopian, Oriental and Australasian Regions including the Moluc-
cas (Kadarsan. 1971; Clifford et al., 1973). During this study it was col-
lected from 3 host species belonging to 2 families. The molossids.
Chaerephon jobensis which ranges from India and Sri Lanka, east to
southern China and Vietnam, and southeast to the Philippines. Borneo.
Bali and the Moluccas, and Mormopterus beccarii which ranges from the
Moluccas east to New Guinea, northern and central Australia and adja-
cent small islands, appeared to be the main hosts but a single specimen
was collected from the pteropodid, Rousettus amplexicaudatus. Ixodes (L.)
kopsteini possesses certain morphological and reproductive features
unknown in other ticks ( Kadarsan, 1 97 1 ). These morphological traits led
Anastos (1950) to exclude this unusual tick from his monograph on
Indonesian Ixodidae because he considered it to be. "probably a special
type of mite."

Ornithodoros sp. larvae could not be identified further so little can be
stated regarding host associations or geographical distribution. Never-
theless, this tick genus occurred almost exclusively on Dobsonia viridis
(70 specimens) although 2 specimens were taken from a female Rouset-
tus amplexicaudatus.

The laelapid mite, Neolaelaps spinosa (Berlese) is parasitic on a variety
of fruit bats in the genus Pteropus Erxleben. It ranges from Sri Lanka to

Australia so the present record from P. temmincki on Seram is expected.

This mite occasionally has been found attached phoretically to nyc-

teribiidbat flies (Maa, 197 la) but this phenomenon was not observed in

the Seram material.

All 4 macronyssid mites were damaged protonymphs and could not
be identified beyond genus. Two genera were collected: Macronyssus,
which is most often retrieved from vespertilionid bats, agreeing with the
Miniopterus australis record documented here, and Trichonyssus which
occurs principally on vespertilionids but also on some other bat families
including Molossidae from which the Seram collections were made.
While the genus Macronyssus is virtually cosmopolitan in distribution,
there does not appear to be any previous records for Trichonyssus outside
of Australia and Tasmania (Radovsky, 1979; Micherdzinski and Dom-
row, 1985; Domrow, 1987).

Seven species of spinturnicid mites were collected. Ancystropus tap-
robanius (Turk) and A zeleborii Kolenati were both taken from Rousettus
amplexicaudatus which concurs with previously documented host re-
cords especially those from southern Asian species of Rousettus (Prasad,
1969; Domrow, 1972; Hadi etal., 1980). Three species of Meristaspis were
identified from different bat hosts. Meristaspis lateralis (Kolenati), which
ranges from the Near East (Palestine and Yemen) southeast to New
Guinea, is principally parasitic on Rousettus species (Delfinado and
Baker, 1963; Prasad, 1969). The present records of Meristaspis lateralis
from Rousettus amplexicaudatus therefore conform to this trend although
the single specimen of Meristaspis lateralis from Dobsonia viridis is an
exception. Meristaspis jordani (Radford) was collected only from Dob-
sonia viridis. Previous records show this mite to be parasitic mainly on
bats of the genus Dobsonia, and to range from Sulawesi and the Philip-
pines to New Guinea and the Bismarck and Solomon Islands (Prasad,
1969; Domrow, 1972). Meristaspis calcarata (Hirst) typically parasitizes
numerous species of Pteropus bats and ranges from Madagascar to Aus-
tralia and a number of Pacific islands (Delfinado and Baker, 1963;
Prasad, 1 969). The present record from P. temmincki fits this distribution.
Paraperiglischrus rhinohphinus (Koch) is associated with numerous
species of Rhinolophus bats, and ranges from the British Isles southeast
to Africa, southern Asia and Australia. In this survey it was collected

Vol. 101, No. 1. January & February 1990 55

from R. euryotis. Spinturnix psi (Kolenati) is another ectoparasite with a
wide geographical distribution. There are records of this mite from
France, southern Europe, Madagascar, southern Asia and Australia. In
this survey, Spinturnix psi was collected only from Miniopterus australis
which concurs with its known host preference for species of Miniopterus
(Baker and Delfinado, 1964; Prasad, 1969; Domrow, 1972).

The above records extend the known geographical distributions of
most of the ectoparasites collected during this survey. Geographical dis-
tributions of the bat species and their associated ectoparasites are not
congruent in the majority of cases. Different bat species are parasitized
by these ectoparasites in other parts of their range. Conversely, a few of
the ectoparasites were more host specific and may be expected to overlap
more closely with the distributions of their hosts. The dispersive abilities
of their volant hosts and the facility of some bat ectoparasites to utilize a
spectrum of host species probably explains, at least in part, the large
geographical distributions of many bat-associated arthropods.

ANNOTATED CHECKLIST OF THE

RHYACOPHILOIDEA AND INTEGRIPALPIA

(TRICHOPTERA) OF ALABAMA 1

S.C. Harris 2 , P.K. Lago 3

ABSTRACT: Distributional records of 132 species of caddisflies in the suborder Annuli-
palpia, (superfamily Rhyacophiloidea) and the suborder Integripalpia (superfamilies
Limnephiloidea, Phryganeoidea, Leptoceroidea, and Sericostomatidea) from Alabama
are listed, along with information on seasonal occurrence, habitat and relative abundance.
This checklist brings the total number of caddisflies known from Alabama to 323 species.

The caddisfly fauna of the southeastern United States has received
considerable attention in recent years and species checklists are now
available for Tennessee (Etnier and Schuster, 1979), North and South
Carolina (Unzickere/ a/., 1982), Kentucky (Resh, 1975), Virginia (Parker
and Voshell, 1981), and Mississippi including southeastern Louisiana
(Holzenthal el al., 1982). This is the third and final contribution in a
series of papers (Harris, 1986a; Lago and Harris, 1987) on the caddisfly
fauna of Alabama. This checklist presents distributional records for 132
species in the families Glossosomatidae and Rhyacophilidae (infra-
order Spicipalpia, Weaver, 1984); Goeridae, Limnephilidae, Uenoidae,
Brachycentridae, Lepidostomatidae, Phyrganeidae (infraorder Pleni-
tentoria. Weaver, 1984); and Odontoceridae, Calamoceratidae, Lep-
toceridae, Molannidae, Helicopsychidae, and Sericostomatidae (infra-
order Brevitentoria, Weaver, 1984). The Hydroptilidae which are also in
the infraorder Spicipalpia (Weaver, 1984) are not included in this chec-
klist, but were compiled in Harris (1986a). Of the 132 species identified
from Alabama, ten were described during the course of the study (Harris,
1986b, 1987, 1989; Vineyard and Wiggins, 1987) and two others will be
described in the near future. The species richness is indicative of the
range of physiographic regions represented in the state. These include
the East Gulf Coastal Plain, Piedmont Plateau, Valley and Ridge, and
Appalachian Plateau, including the Highland Rim Plateau and Cum-
berland Plateau subregions (Sapp and Emplaincourt, 1975).

coded county records. These counties and their location, both within the
state and within a physiographic province, are depicted in Figure 1.
General information on distribution and abundance in the state is
included with each species, followed by collection months and numbers
of specimens examined ( ). In most cases only adult males were exam-
ined, except as noted. Detailed locality and collection information will
be provided in an overall summary of the caddisfly fauna of the state, to
be published later. This checklist represents over 600 collections made
primarily with black-light traps between 1981 and 1987. Voucher speci-
mens are maintained in the insect collections of the Geological Survey of
Alabama and the University of Alabama.

SUMMARY

This checklist, combined with those previously published (Harris, 1986a. 1988; Lago
and Harris, 1987), brings the total number of caddisflies in Alabama to 323 species. This
total is comparable to the 298 species reported from Tennessee (Etnier and Schuster, 1979)
and the 330 species from North and South Carolina (Unzicker et ai, 1982). This species
total is probably a reflection of the range of physiographic regions represented in the state
(fig. 1) as well as the result of intensive collecting. Collections from neighboring Mis-
sissippi, for example, which lies almost entirely within the East Gulf Coastal Plain yielded
only 139 caddisfly species (Holzental et al., 1982).

The 323 species of caddisflies were distributed among 57 genera and 17 families. Hyd-
roptilidae were best represented (97 species), followed by Leptoceridae (56 species), Hyd-
ropsychidae (47 species), and Polycentropodidae (32 species). These four families which
accounted for 72% of the total fauna in Alabama are noted for their ability to exploit warm
water habitats typical of Alabama (Wiggins, 1977).

COLLECTIONS OF DUFOUREA VERSATILIS
(HYMENOPTERA: HALICTIDAE) FROM IDAHO 1

Sharon Luce Walsh^

ABSTRACT: Dufourea versatilis was collected outside California for the first time on
Mimulus nanus (Scrophulariaceae) at two areas in central Idaho during the summers of
1987 and 1988.

Insect visitors oi Mimulus nanus (Scrophulariaceae) were collected in
the summers of the 1987 and 1988 at two locations in central Idaho: one
at Craters of the Moon National Monument, Butte County and the other
north of Ketchum, Elaine County. The vegetation in both areas consists
of rabbit-brush (Chrysothamnus nauseosus), sagebrush (Artemesia triden-
tata), antelope bitter-brush (Purshia tridentata), and many annual and
perennial herbs. The mean annual precipitation in each area is approx-
imately 38 cm. Insect visitors were collected twice weekly starting in late
May when the plants started blooming and continued until plants stopped
blooming. In 1987 insects were collected through July, whereas in 1988,
because of drought conditions, all M. nanus plants were finished bloom-
ing by the first of July.

One insect collected, Dufourea versatilis (Bridwell) (Halictidae), pre-
viously had been collected only in California (Hurd 1979). Both male
and female bees were collected, but during 1987 only 1 male was collec-
ted at the Craters site whereas 1 male and 3 females were collected from
the Ketchum site. In 1988 noD. versatilis were collected at the Craters site,
but 19 of the 25 insect visitors collected at the Ketchum site were D. ver-
satilis. Of these 19, 14 were females and 5 were males.

Dufourea versatilis is an oligolege of Mimulus species in California
(Hurd 1979). In all sampling periods during this study, D. versatilis was
observed foraging only on M. nanus at the two areas. It is likely that it has
never been collected outside California because insect pollinators of
most Mimulus species have not been collected elsewhere. I predict that D.
versatilis will be found in any location that has populations of M. nanus,
including eastern Oregon, eastern Washington, northern Nevada, wes-
tern Montana, central and western Idaho, and western Wyoming around
Yellowstone and Grand Teton National Parks.

TWO IMMIGRANT SYNANTHROPIC FLOWER

FLIES (DIPTERA: SYRPHIDAE) NEW TO

NORTH AMERICA 1

F. Christian Thompson , Frank D. Fee-', Larry G. Berzark'*

ABSTRACT: Two flower flies are recorded from North America for the first time: Eris-
talinus(Eristalodes)taeniops -Florida; and Syrittaflaviventris- Texas and Mexico. Diagnostic
characters are given for these species, along with biological data.

Two flower flies are recorded from North America for the first time:
Eristalinus (Eristalodes) taeniops fWiedemann) - Florida; and Syritta
flaviventris Macquart - Texas and Mexico. Both are hemisynanthropes,
close associates of human ecosystems, and common filth flies in the Old
World. Diagnostic characters are given for these species, along with
biological data.

Two synanthropic flower flies, one presently unknown in the New
World and the other unknown from North America, were recently col-
lected for the first time in the United States. Syrittaflaviventris Macquart
was collected in southern Texas and Mexico, and Eristalinus taeniops
(Wiedemann) was collected in southern Florida. Both belong to pre-

Syritta flaviventris Macquart

Syritta flaviventris Macquart, 1842: 135. Type locality: Senegal. Type depository: Male,

MNHN, Paris.
Syritta spinigera Loew, 1848: 331. Type localities: Greek islands, Sicily & Turkey. Type

depository: synrypes, males & females, ZMHU, Berlin.

Syritta flaviventris andpipiens are so similar that no description is given.
The above key serves as a differential diagnosis for these species.

North American Records: MEXICO, NUEVO LEON, Apodaca, "E. L.
Mezquital", 26 May 1984 (C. Alvarez Pereyra; IIBIII lot # 84-07029.)
USA, TEXAS, Hidalgo County, Bentsen-Rio Grand Valley State Park, 2 1
October 1984 (F. D. Fee), 1 female, Relampago, 15- 19 October 1986 (F. D.
Fee), 6 males, 1 female. The material from Texas was collected in a
locality about 48 miles east on the Mexican specimen (initial record).
The specimens from Relampago were all collected in or along the banks
of an abandoned drainage ditch or canal. The males were patrolling and
visiting flowers of Schinus, Serjania and Polygonum. The female was
taken on Polygonum. Voucher specimens deposited in the National
Museum of Natural History, Smithsonian Institution, Washington; other
specimens retained in Fee Collection.

Syritta flaviventris is readily distinguished from pipiens, the only other
New World species of the genus, by the absence of a spurious vein (fig. 4)
and the presence of a strong basoposterior ventral spur on the male hind
femur (fig. 5); and from other Old World congeners by male genitalic
characters (Thompson, 1972: 170, fig. 69).

Syritta is not indigenous to the New World but has been introduced with
Man. The larvae of Syritta breed in almost any kind of waste, andpipiens
has been frequently reported to breed in human feces(Farrar 1987: 361,
Henning 1952: 189). Flaviventris was first recorded from the New World
by Fluke (1960), who recorded the species from Brazil, Sao Paulo, collec-
ted in 1954. Marnef (1967) recorded it from Chile as Austrosyritta cortesi
Marnef (synonymy by Thompson 1971), and Argentina was added to its
New World distribution by Thompson, et at. (1976: 119). In the Old
World, S. flaviventris ranges from the Mediterranean (Spain to Bulgaria
and Turkey), south to South Africa (Cape of Good Hope), and is found
on Saint Helena. Campos and Pena (1973: 225; Smith and Vockeroth
( 1980: 507)) recorded it from Easter Island. Syritta pipiens is found through-
out northern North America and is recorded as far south as central Mex-
ico (Durango and Chihuahua) (Thompson, et al. 1976: 119).

New World record: USA, FLORIDA, Dade County, Florida City. 7
December 1985 (L. G. Bezark) 1 male (USNM). The specimen was swept
from Bidens, a common weedy composite, along a hedgerow of tamarisk
trees (Tamarix] adjacent to a field of cultivated tomatoes.

Eristalinus taeniops is easily distinguished from all other New World eris-
talines (species with sinuate R4+5 vein) by its fasciate eyes (fig. 1). The
only other species of Eristalinus known from the New World, aeneus
Scopoli, has punctate eyes (fig. 2), and all other New World eristalines
have no maculation on the eyes. Eristalinus taeniops belongs to a small
group of species of Eristalinus which have distinct fasciae on the eyes in
addition to puncta.

Eristalinus is not indigenous to the New World, but two species have now
been introduced. Eristalinus larvae, commonly called rat-tailed maggots,
have been recorded to breed in putrid waters associated with man, such
as sewers, privies, etc (Ferrar 1987: 359-360, Hennig 1952: 184-185). Eris-
talinustaeniops has never previously been recorded from the New World.
In the Old World, the species ranges from the Mediterranean (Spain to
Greece and Bulgaria), east to Pakistan, and south to South Africa (Cape
of Good Hope). Eristalinus aeneus Scopoli ranges from California to
Ontario and New Hampshire, south to Texas and Georgia; and in the
Old World aeneus ranges throughout the Palaearctic Region (Peck 1988:
182, Knutson el alia 1975:347) and has been introduced into Tanzania
in Africa (Smith and Vockeroth 1980: 501) and Wake Island, the Hawaiian
and Gilbert Islands in the Pacific Ocean.

REDESCRIPTION OF MALES, BIOLOGICAL

NOTES, AND IDENTIFICATION OF AMERICAN

ACANTHOCHALCIS (HYMENOPTERA:

CHALCIDIDAE)i

Jeffrey A. Halstead^

ABSTRACT: Males of Acanthochalcis nigricans and /I. unispinosa are redescribed, voucher
specimens designated, diagnostic characters illustrated, and a key to the American species
presented. Characters to distinguish Acanthochalcis from other Nearctic Chalcididae are
presented. The taxonomic and biological information on Acanthochalcis is summarized
and new hosts, rearings, and floral visitations are recorded. A third species, A. gigas, is
known from Madagascar.

Acanthochalcis are the largest chalcidids in the Nearctic region with
males ranging in length from 6 to 1 1 mm and females from 7 to 24 mm.
These wasps are black with reddish brown to brown legs and smokey or
yellowish wings. Females are unique among Nearctic Chalcididae in
having a spear-like ovipositor which projects posteriorly a distance
equal to or greater than the length of the abdomen. Acanthochalcis are
uncommonly collected, though have been taken by sweeping flowering
vegetation and netting individuals around host inhabiting trees and
shrubs.

To improve the taxonomic information on American Acanthochalcis,
the males of A. nigricans Cameron and A. unispinosa Girault are rede-
scribed, the species distinguished in a key, the taxonomic history re-
viewed, and characters presented to distinguish this genus from other
Nearctic Chalcididae. This information improves the brief original
male descriptions and is needed to identify Acanthochalcis and its Amer-
ican species. Male voucher specimens are deposited with their female
holotype for use in future studies. The redescriptions will also be useful
to delineate the presently unknown male of A. gigas Steffan (from Mada-
gascar), and help establish the relationship between American and
Madagascaran Acanthochalcis.

Both American Acanthochalcis are parasitoids of buprestid beetle lar-
vae which inhabit oak trees (Quercus spp.) (Halstead and Haines 1985);
however, new information indicates buprestid hosts in saltbush (Atri-
plex sp.), ocotillo (Fouguieria splendens), and Baccharis sp. Overall, the
biological information on Acanthochalcis is very limited. This informa-
tion is summarized and new host, rearing, and floral visitation records

are presented to encourage and aid future research.

Steffan (1959) recognized \nAcanthochaIcis two American species A
nigricans (Cameron 1884) and A. unispinosa (Girault 1917, 1921; in Gordh,
etal. 1979) and A. gigas (Steffan 1950) from Madagascar. Drawings of the
apex of both the abdomen and scutellum for nigricans were presented.
Characters for the previously unknown males of A. nigricans and A. unis-
pinosa were presented in a key. The male of A. gigas is unknown. Steffan
also proposed subgenera, placing nigricans mAcanthochalcis, unispinosa
in Belochalcis, and gigas in Trypanochalcis, but the designation of sub-
genera for each species seems unwarranted on the basis of the few
species and at least for nigricans and unispinosa on morphological
grounds.

Acanthochalcis, the only member of the tribe Cratocentrini in the
Nearctic region, may be distinguished from other Nearctic Chalcididae
by the following characters: head without horns on dorsal area of frons,
antennae inserted in center of frons, abdomen sessile, hindtibiae with
one apical spur and the apex obliquely sinuate (Brachymerinae); post-
marginal vein much longer than marginal vein, scrobe cavity almost
touching vertex of clypeus, mesopleuron deeply excavated by a aceta-
bulum which receives the mesotibia and mesofemur in response, (9)
with 4 visible tergites, (cT) with 7 visible tergites (Cratocentrini); pro-
podeum produced laterally into a flattened triangular mass (dorsal
view).

and female genitalia are described and figured. The spring emerging adults were taken
near small streams which may dry up in summer. Details of the physicochemical and
biological characteristics of the topotypical stream are given.

While surveying benthic organisms of intermittent streams. Harp
collected examples, both adult and larvae, of a number of Trichoptera
that were sent to Flint for identification. In these collections a species of
Lepidostoma that appeared to be undescribed was discovered. Conse-
quently, correspondence with D.E. Bowles at the University of Arkansas
revealed that he had additional examples of this species from other
localities in Arkansas and Oklahoma. The recently published revision
of the New World species of Lepidostoma (Weaver 1988) confirms that
this species is heretofore unknown.

Lepidostoma (Nosopus) ozarkense Flint & Harp, new species

Adult: Length of forewing, male 6 7mm, female 7 7.5mm. color in alcohol uniformly
dark brown. Venation in both sexes typical of group (Weaver 1988, Figs. 46a. 46b). Male
with scape about 3 times as long as broad; maxillary palpus apparently one-segmented,
filled mesally with long spatulate hairs (essentially as in Weaver 1988, Fig. 32). Male
genitalia (Figs. 1-4): Ninth segment annular, widened ventrally, with a ventrolateral brace.
Tenth tergum elongate, blunt apically. with scattered setae arising from protuberant bases;
with a narrow, dorsomesal incision about a third length of segment, with a darkened, inter-
nal sclerotization around base of incision; with a basoventral process as long as dorsal lobe
and tapering to an apical point in both dorsal and lateral aspects. Clasper with basodorsal
process rather straight,apex truncate in dorsal and obliquely truncate in ventral aspect,
lying on segment one; segment one slightly inflated basally, hirsute ventrolaterally, mem-
branous mesoventrally, curved and bluntly pointed mesad; segment two a small subapical
lobe directed mesad. Phallus lacking sclerotized parameres, but with a bilobed, apicodor-
sal, membranous appendage; apex slightly decurved, with a darkened internal phallo-
tremal sclerite, beyftnd which it is membranous. Female genitalia (Figs. 5-6): Eighth

ted mesally by a lightly sclerotized band along anterior margin. Ninth tergum with a long
anterolateral apodeme. ventral margin strongly concave; dorsally with a distinct projec-
tion subapically. Membrane ventrolaterally between eighth and ninth segments bearing
convoluted sclerotized and semisclerotized bands. Vaginal sclerite in ventral aspect with

This species is a member of the Modestum Group (Weaver 1988:35)
and is closely related to L. Ontario Ross. These are the only two species in
which the males possess a basoventral process from the tenth tergum
and the only apparently significant and consistent difference between
them lies in the length and shape of this process. In ozarkense the process
is only as long as the tenth tergum and is pointed in both lateral and dor-
sal aspects. However, in Ontario this process is almost 1 .5 times as long as
the tenth tergum, and, although it may appear pointed or furcate in
lateral aspect depending on the angle, in dorsal aspect it is flattened,
curved, widened and shallowly furcate apicad (Ross 1941, Fig. 98; Weaver
1988, Fig. 72). The females are quite similar in all species of the group,
and specific differences are less certain. However, the lightly sclerotized,
convoluted bands ventrad of the ninth tergum and the projecting lateral
angle of the vaginal sclerite in ozarkense appear to be diagnostic.

DISCUSSION

This species brings to seven the number of species described in the
Modestum Group, all of which are limited to eastern North America.
Four of the species, lydia Ross, modestum (Banks), Ontario Ross, and pic-
tile (Banks), have rather similar distributions, running in general from
Newfoundland or Quebec south along the Appalachian Mountains into
the western Carolinas or northwestern Georgia (cf. Fig. 7, the distribu-
tion of Ontario). Three species appear to have very restricted ranges: com-
pressum Etnier & Way in Cumberland Co., Tennessee, weaveri Harris in
Tuscaloosa Co., Alabama, and ozarkense n.sp. in Independence. Johnson.
Logan, and Pope Cos., Arkansas and Latimer Co., Oklahoma. All of
these species occupy areas outside the broad range of Ontario. This pat-
tern is suggestive of either relictual distributions resulting from expand-
ing and contracting ranges related to earlier advances and retreats of ice
sheets, or random dispersal events from the main range of the species
group.

ECOLOGICAL - BIOLOGICAL DATA

The topotypical stream, an intermittently flowing second-order tri-
butary of Salado Creek, is located in the Boston Mountains of the Ozark
Plateau. The sampling site (Fig. 8) was a 100m stretch of the stream
which parallels highway US 167, approximately 0.8km south of the

ENTOMOLOGICAL NEWS

Salado Creek bridge (Harp 1988). The stream margins are heavily tores-
ted, primarily with loblolly pine (Pinus taeda L.), shortleaf pine (Finns
echinata Mill.), eastern redcedar (Juniperus virginiana L.), southern red
oak (Quercus falcata Michx.), and white oak (Quercus alba L.).

Selected physicochemical parameters were measured from 27 Dec
1986 through 18Jul 1987(Table 1). This unnamed intermittent stream is a
slightly acidic, soft-water stream. Alkalinity ranged between 19 88ppm
with the highest values recorded during low flow. The pH ranged from
6.6 7.0, averaging 6.7. The low alkalinity and pH values reflect the soil
type, Enders stony fine sand loam (Ferguson et al. 1982).

Flow volume measured 120 300,000cc/sec. Temperature ranges in-
cluded: water 5.0 27.5C, and air, -1.5 28C. The first adult Lepidos-
toma ozarkense, a male, was taken on 2 1 March. Flow peaked on this date;
water temperature was 15C, and air temperature 24C. The remaining
specimens were collected on 18 April. On this date the flow measured

19,000cc/sec; water temperature was 14.5C, and the air was 25 U C. Thus
this trichopteran was present during high flow and when water tempera-
ture was above 14C.

Aquatic samples, totalling fifteen, were taken twice monthly, each the
result of a two hour collecting period. A Turtox Indestructable Dip Net
was the primary collecting instrument, but smaller samples were taken
from a Tyler Standard Screen (mesh size 0.295mm) after disturbing the
bottom. Adults, which were taken incidentally, were not included in the
sample statistics. The aquatic stages of a minimum of 54 taxa were collec-
ted in the samples. Of these taxa, 46 were insectan: 12 beetles, 10 stone-
flies, 8 caddisflies, 6 flies, 5 mayflies, 4 water bugs, and 1 fishfly. The
eleven most common insects (numbers 10 and 1 1 had identical counts),
in order of abundance, were: Amphinemura delosa (Ricker), Prosimulium
spp., Pseudocloeon spp.,Ameletus spp., hoperla spp.,Agapetus illini Ross,
Neophylax concinnus McLachlan, Clioperla sp.. Tipula spp.. Stenonema
femoratum (Say), and Perlesta spp. A paper presenting the full results of
the survey is being prepared by the junior author.

Although 37 Lepidostoma larvae (fifteenth in order of abundance)
were collected at the topotypical site, they were not reared, and we feel it
wisest not to risk an erroneous aasociation at this time. Both Bowles and
Harp are planning work on the immature stages of this species.

A NEW SPECIES OF NEOTRICHIA (TRICHOP-

TERA: HYDROPTILIDAE) FROM COLORADO
WITH ADDITIONS AND CORRECTIONS TO THE
DISTRIBUTION AND RECORDS OF COLORADO

TRICHOPTERA 1

D.E. Ruiter 2

ABSTRACT: Neotrichia downsi, new species, is described from Jackson County, Colorado.
Illustrations of the male and female genitalia are provided. Additions and corrections to
the list of Colorado Trichoptera are also included. Fifteen species are added to the Colorado
list, bringing the total number of species reported from Colorado to 188.

As part of continuing studies on the taxonomy and distribution of
Rocky Mountain Trichoptera, a new hydroptilid caddisfly was dis-
covered in material collected by Dr. Wilbur G. Downs from the North
Platte River. Notes on new distributional records of other Colorado
Trichoptera and corrections to the list by Herrmann et al. (1986) are
also provided.

Neotrichia downsi, new species
Figure 1

Male: Body and appendages typical for subgenus, light brown, total body length 2 mm.
Bracteole of IX segment constricted throughout basal third. In dorsal view, membranous X
tergite evenly tapered, a pair of stout setae located laterally, approximately one-third from
apex. Inferior appendages heavily sclerotized; ventrally triangular, with a minute, mesal
tubercle near midpoint; rapidly tapered in lateral view, apex slightly upturned, bearing
several minute tubercles. Subgenital plate heavily sclerotized, massive; in lateral view
hooked slightly ventrad apically, extending 0.75 length of inferior appendage. Phallus with
long, wide basal portion, tapering evenly to constriction at spiral process, apical portion
slightly expanded at base with apex incised; spiral process encircles phallus approx-
imately 1.5 times.

Female: Body and appendages typical for subgenus, light brown, no apparent sexual
dimorphism, total body length 2 mm. Sclerotized portion of VIII sternite resembling an
inverted champagne glass. Bursa with apex long and slender. Scale-like setae at distal
margin of VII sternite smoothly rounded at apex.

Etymology: Named for the collector, Wilbur G. Downs, in recognition of his extensive
collection of insects from the type locality.

Holotype male: Colorado, Jackson County, Ginger Quill Ranch at the North Platte
River, altitude 2,370 meters (7,700 feet) above mean sea level, 7 July 1986, W.G. Downs,
black light trap collection. Deposited in the Illinois Natural History Survey collection.

Paratypes: Same as above, except 4 July 1987, 1 male, 1 female. The female is in poor
condition, only the abdomen is relatively intact. Deposited in the United States National
Museum collection.

This species belongs to the collata species group, closely related to N.
okopa Ross, N. sonora Ross and N. osmena Ross. This species appears
most similar to N. okopa Ross from which it can be readily separated by
the dorso-ventrally flattened inferior appendages, constricted basal third
of the spatulate lateral appendages, and the evenly tapered X tergite. The
new species can be distinguished from N. sonora by the absence of the
long membranous IX tergite, and lack of long, sclerotized lateral projec-
tions on the tenth tergite. Downsi differs from osmena by the shape of the
inferior appendages and lack of the sclerotized, forceps-like structure of
the X tergite. However, the phallus ofN. downsi is indistinguishable from
that of N. osmena. The female association is inferred from the syn-
chronous collection with the male and the distinct difference from N.
halia Denning, the only other Neotrichia species collected at the type
locality during nearly ten years of collecting.

Corrections and New Distributional Records

Lepidostoma grisea (Banks) originally included by Herrmann et al.
(1986) is removed from the Colorado distribution list. This record was
questioned by John Weaver (personal communication) and after a diligent
search, this specimen could not be located. Weaver (1988), also syn-
onymized several species of Lepidostoma occurring in Colorado (L. mon-
eka Denning 1968 = L. ormea Ross 1946; L. mira Denning 1954 = L.
cascadense (Milne) 1936; L. strophis Ross 1938 = L. cinereum Banks 1899;
L. veleda Denning 1948 = L. pluviale (Milne) 1936).

Since publication of the Colorado list (Herrmann et al., 1986) several
new records have been published and additional species collected through
the efforts of W.G. Downs, B.C. Kondratieff and this author. The county,
known Colorado emergence period, and notes where appropriate are
listed below.

Culoptila cantha Ross, Jackson County, 2 August.

Cheumatopsyche speciosa (Banks), Moffatt County, 11 July. This

appears to be the first record of this species west of the continental divide.

Previously reported from locations in the east with the most western

records being from Montana and Oklahoma (Gordon, 1974; Nimmo,

1987).

Hydropsyche alhedra Ross, Grand and Jackson Counties, 23 July -

20 August.

Hydropsyche bidens Ross, Weld County, 3 August. Previously reported

from the eastern portion of the Great Plains (Hamilton and Schuster,

Vol. 101. No. 2. March & April 1990 91

1979; Nimmo. 1987). Its collection in eastern Colorado indicates it has
successfully crossed the prairie to the upper Platte River basin.
Hydropsyche slossonae Banks, Grand County, (Schefter and Wiggins.
1986). Jackson County. 15 July - 16 August.

Hydroptila angusta Ross. Moffatt County. 1 1 July. This appears to be
the first record for this species from west of the continental divide. Pre-
viously reported from the east with western records in New Mexico.
Texas and Kansas (Ross. 1944; Schuster and Hamilton. 1978).
Mayatrichia ayama Mosely. Mesa County'. 30 July.
Ceraclea arielles (Denning). Jackson County. 15 July - 9 August.
Ceraclea resurgens (Walker). Grand and Moffat Counties. (Herrmann.
1988) 25 July - 1 August.

Limnephilus apache Flint. Larimer and Pueblo Counties, 27 July - 2
August. This species has not been reported since Flint's 1965 description
from collections in Arizona and New Mexico. The collections in Larimer
and Pueblo Counties represent significant northern distributional
extensions.

Limnephilus selatus Denning, Grand County, 3 August.
Pycnopsyche guttifer (Walker), Jackson County, 31 July - 20 Sep-
tember.

Polycentropus aureolus (Banks). Jackson County, 1-9 August. Prev-
iously reported from the northern states and Canada (Nimmo. 1986)
with the nearest records from Idaho and North Dakota.
Agrypnia colorata Hagen. Larimer County, 28 June.A colomla is also a
seldom reported species. Most records are from Canada (Betten. 1934;
Ross and Spencer, 1952) with the nearest previous records from Mon-
tana (Roemhild, 1982).

Gumaga griseola (McLachlan). Yuma County, 25 June. (Kondratieff
and Ward. 1987). I have examined this specimen and while the specimen
was about half the typical size of specimens from California, the geni-
talia were nearly consistent with California specimens. Hamilton and
Schuster (1980) also noted structural differences in Kansas populations
of G. griseola. While it is clear the collection of Gumaga is a new record
(including a new familial record) for the state, further collections will be
necessary to determine the variation within the species.

Given the fairly detailed lists available for several of the adjacent
steles (Kansas: Schuster and Hamilton, 1978; Hamilton and Schuster.
1979, Hamilton and Schuster. 1980; Utah: Baumann and Unzicker.
1981; Wyoming: Ruiter and Lavigne. 1985). it appears many of the
species which may be on the fringe of their distributional areas are also
extremely localized in their distribution, having not been reported from
neighboring states.

A NEW SPECIES OF ZONANA (HOMOPTERA:
CICADELLIDAE) FROM VENEZUELA 1 2

Paul H. Freytag-'

ABSTRACT: A new species ofZonana is described from Venezuela. This fairly small genus
previously was known from only two species from Central America, so the known range of
the genus is extended to the upper part of South America.

New species ofZonana is described at this time from Venezuela. This
species is the third species placed in this genus; the other two were des-
cribed from Central America (DeLong and Freytag 1963).

Zonana bilobata sp. n.

(Figures 1-5)

Length of males 6.4-6.7 mm.; female unknown.

Resembling flamma in general size, shape and color, but differs in shape of aedeagal
shaft and processes.

Color: Similar to flamma, except with three additional dark spots along commissure of
each forewing. Dark punctures present on pronotum and along basal costal area of
forewing.

Male genitalia: Pygofer truncate and bilobed at apex, with small dorsal subapical
lobe. Genital plate short with truncate apex. Style short, sharply pointed at apex, with an
enlarged rounded caudal lobe. Aedeagus short, subapical ventral cleft forming lateral
hook-like lobes with several small spines along ventral margin; apex rounded, with two
darker sclerotized spine-line areas.

Holotype male: VENEZUELA. Aragua. El Limon, 450 m., 26- VI- 1974, En Luz de Mer-
curio, F. Fernandez Y. & F. Fernandez H., in the University of Central Venezuela collec-
tion. Paratypes: One male, VENEZUELA. Aragua, El Limon. 450 m.; 1-1-1981. F. Fer-
nandez Y. Coll.. in the University of Kentucky collection; one male. VENEZUELA.
Bolivar. Rio Surukum. Carretera, Sta. Elena Icabara. 850 m.. 19-31- 1-19895. F. Fernandez
Y., Anibal Chacon and Jurg Demarmels Colls.; one male. VENEZUELA. Miranda. Valle
Rio Cuira, 280m.. S. of Panaquire.approx. 10 12' N; 66 17' 0, 18-21 -IX- 1979. F. Fernandez
Y. & J. A. Clavijo Colls., both in the University of Central Venezuela Collection.

Note: This species can be separated from the closest species,/7awwa ,
on the basis of the distinct aedeagus and the additional punctures on the
pronotum and costal area of the forewing.

I wish to thank the late Dr. Fernandez Yepes who was instrumental in
collecting this most interesting species and making the specimens avail-
able for study.

EURYPAUROPUS SPINOSUS (ARTHROPODA:
PAUROPODA: EURYPAUROPODIDAE) FROM

ARKANSAS AND A KEY TO THE NORTH
AMERICAN EURYPAUROPUS SPECIES 1 ' 2 ' 3

Robert T. Allen 4

ABSTRACT: Eurypauropus spinosus is reported for the first time in Arkansas. A key is given
to the three North American species of Eurypauropus.

In the closing section of his paper on the Pauropoda of the United
States, Scheller (1985) notes "that there are large lacunae in the knowl-
edge of the ranges" of most pauropod species. This paper serves to fill in
one of those lacunae for Eurypauropus spinosus Ryder, and to provide a
key, based on information from the literature whereby other workers can
identify Eurypauropus specimens.

The family Eurypauropodidae is easily recognized by the large,
sclerotized tergal plates on each body segment. These plates conceal the
head, terminal segments, and the legs when viewed from above. Brues, et
al. ( \ 954) present a key that will allow workers to place Pauropoda in the
correct families. As far as known, Eurypauropus is the only genus in the
family Eurypauropodidae occuring in North America.

In the United States four species of Eurypauropus have been des-
cribed, one of which has been synonymized. Eurypauropus spinosis ap-
pears to be the most common species and has been reported from eleven
states, Fig. 4. Recent collections, listed here, add two new localities from
Arkansas to the list of areas from which E. spinosus is known. The two
Arkansas localities are as follows: Pulaski County, Pinnacle Mountain
State Park, east summit trail, 25 January 1988, Robert T. Allen collector;
Yell County, entrance to Mount Nebo State Park, 15 April 1988. C. E.
Carlton collector.

Eurypauropus californicus MacSwain & Longham was described
from California, but was reduced to a synonym of E. spinosus by Remy
(1956). In the same paper Remy described a new species, E. uncigerhom
Kentucky. In the most recent and complete paper on the Pauropoda of
the United States, Scheller (1985) described E. washingtonensis from
Olympic National Park in Washington State. The following key, based
on characters extracted from the papers by Remy (1956) and Scheller

SCIENTIFIC NOTE

DYSCINETUS MORATOR (COLEOPTERA: SCARABAEIDAE)

FEEDING ON ROOTS OF AZALEAS

(RHODODENDRON SPP.) 1 ' 2

C. L. Staines, Jr. 3

Dyscinetus morator (Fab.) (Coleoptera: Scarabaeidae), a common scarab distributed
from New York south to Florida and west to Texas and Mexico (Gordon & Anderson. 1981),
is widely distributed in Maryland (Staines, 1986). The adults are attracted to lights and
remain in the area of the lights during the day by hiding under available debris (Woodruff,
1970). Dyscinetus morator has been reported to attack rice, Oryza saliva L. (Anonymous,
1953); pangola grass pastures, Digitaria decumbens Stent. (Anonymous, 1956); caladium
bulbs, Caladium x hortulanum, cranberry, Vaccinium macrocarpon Ait. (Woodruff, 1970);
corn, Zea mays L. (Anonymous, 1980); carrot, Daucus carota L., radish, Raphanus sativus L.,
lettuce, Lactuca saliva L. (Foster et al.. \986); and waterhyacmth.Eichhorniacrassipes (Marl.)
Solms (Buckingham & Bennett, 1989). This species is associated with wet soils and marsh
areas (Anonymous, 1980; Buckingham & Bennett, 1989).

On 2 August 1982, during a routine inspection of a commercial nursery in Baltimore
County. Maryland there were discovered larvae, pupae, and teneral adults of an unknown
scarab around the root zone of container-grown azaleas (Rhododendron spp.). All life
stages were abundant and root feeding was obvious on the azaleas. E. J. Ford, USDA,
APHIS, PPQ, Baltimore (retired), identified the adults as Dyscinetus morator. the rice
beetle.

The azalea growing area of this nursery was bounded on three sides by salt marsh. The
azaleas were grown in containers and were maintained under damp conditions, thus pro-
viding a suitable habitat for the beetle. The production area was not lighted, so the infesta-
tion did not result from light-attracted adults. Adult beetles may have been attracted by the
moist, high organic matter content of the potting mixture used by the nursery.

This is the first report of Dyscinetus morator colonizing a woody ornamental. Subse-
quent surveys in this nursery have failed to yield further populations of this beetle in
azaleas, though the beetle is common outside of the growing area.

SEASONAL FLIGHT ACTIVITY OF MALE
VELVET ANTS (HYMENOPTERA: MUTILLIDAE)

IN SOUTH FLORIDA 1

Mark Deyrup , Donald Manley^

ABSTRACT: Seasonal male flight data from a four-year study are presented for 19 species
of mutillids belonging to the genera Ephuta, Photomorphus, Pseudomethoca. Sphaerop-
thalma, and Timulla. A total of 2,391 specimens was collected. At the study site in southern
Florida, most species flew during at least 8 months of the year. Two species flew only late in
the year. All species showed marked fluctuations in abundance from year to year.

Velvet ants (Hymenoptera: Mutillidae) are solitary parasitoid wasps,
most of them having as hosts pupae or mature larvae of bees and wasps
(Mickel, 1928). Male flight activity is particularly important for gene flow
in this group, as females are always apterous, and aerial dispersal is by
males. Males of a few species pick up and transport females, and might
cross barriers that would baffle an earth-bound female (Evans, 1969). We
have collected in Malaise traps copulating pairs of Timulla floridensis,
Ephuta floridana, E.pauxilla, and an associated pair of E. slossonae. Male
flight activity also offers the best methods for estimating relative num-
bers of adults of a species, as the males seem rather vulnerable to Townes
traps (modified Malaise traps). Females can be sampled with pitfall
traps, but we have found that the numbers of specimens collected in such
traps is relatively small, even when there are many traps and their
efficiency is enhanced with long metal barriers (drift fences) that direct
the mutillids into the traps. Nothing has been published on the seasonal
flight patterns of male mutillids. The purpose of this paper is to con-
tribute basic information on this little-known group of insects, and to
provide a data base that could be used in comparative studies of sea-
sonality elsewhere.

MATERIALS AND METHODS

The study site is on the Archbold Biological Station (Highlands
County), located at the southern end of the Lake Wales Ridge in south-
central Florida. The site is in a transitional zone between warm and sub-
tropical zones. Winters are mild and dry, with temperatures during some
years falling below 0C for a few hours. Sheltered microhabitats are

frost-free. Summers are warm and humid, with daytime temperatures
over 25C. Mutillid species diversity is high, with over 30 species known.
The vegetation of the study site is a thin canopy of sand pine (Pinusclausa
Chapman), with a thick 1.5 - 3.5m understory of scrub oaks (Quercus
spp.), staggerbush (Lyonia spp.), silk bay (Persea humilis Nash), scrub
pawpaw (Asimina obovata Nash), and scrub hickory (Carya floridana
Sargent). The paths through this thick brush appeared to act as flight cor-
rdiors for mutillids.

Mutillids were collected in 2 small Townes traps (modified Malaise
traps) that were set up across 2 east-west paths. The traps were kept in
place and continuously monitored from May 1983 through December
1986. Each trap was annually replaced with an identical trap to forestall
the effects of wear. Specimens were collected 3 times a week. The mutil-
lids were identified by the authors. Specimens of all species are in the
collection of the Archbold Biological Station and in the collection of
Donald Manley. Synoptic collections of most species have also been
deposited in the Florida Collection of Arthropods (Gainesville) and the
collection of Denis Brothers (University of Natal, Pietermaritzburg,
South Africa).

RESULTS

Over the 4-year period, the traps collected 2,391 specimens belonging
to the genera Ephuta, Pseudomethoca, Timulla, Photomorphus, and
Sphaeropthalma. Many specimens of Dasymutilla were also collected;
these are not discussed here because of problems with the identification
of some species.

DISCUSSION

At the Archbold Biological Station, males of most mutillid species
are active over a long period. Eight of the 12 species represented by at
least 25 specimens were active during 8 or more months of the year. The
prolonged flight season is likely to be related to the mild climate of the
study site, though complementary data from farther north are needed to
support this conclusion. As can be seen from the graphs (Figures 1-12),
most species are slow to begin flight activity in the spring. Flight activity
is seasonally less symmetrical than monthly average temperatures at the
station. Two species, P. oculata and P. simillima, have flight seasons res-
tricted to late in the year (September-December). There are no corre-
sponding spring-flying species. One species, P. paulus, shows a consis-
tently bimodal pattern reflecting a reduction in numbers in August
and September.

When species are active over a long period, a record of flight activity
does not provide good estimates of longevity. P. oculata and P. simillima,
with their short flight seasons, pro vide more useful information. Assum-
ing that large reductions from one month to the next reflect natural mor-
tality rather than a drastic effect of the traps on local populations, many
males of these species must live a month or less. The short life spans of
these species may not be typical if cooler temperatures in December and
late November are killing males. There is a case of an individual male
Dasymutilla foxi (Cockerell) that lived about 6 months in captivity (J.
Schmidt, personal communication).

The flight activity of males is presumably related to emergence of
females. Females apparently mate only once, immediately after emer-

102 ENTOMOLOGICAL NEWS

gence (Brothers, 1972; J. Schmidt, personal communication). Male flight
activity need not closely reflect total seasonal activity of females, as at
least some female mutillids appear to be long-lived insects (Schmidt,
1978). Female P. oculata and P. simillima, for example, are active in spring
and early summer, when there are no records of males. The fall and win-
ter emergence of these species may actually indicate a heavy dependence
on early spring hosts, rather than a dependence on fall or winter
hosts.

All species showed marked variation in annual abundance, with
maximum annual collections at least twice minimum collections. The
seven most frequently collected species showed no clear evidence that
their numbers were similarly and simultaneously affected by common
factors such as rainfall or temperature. The fluctuations seen in these
species may be unintelligible until we have identified hosts and know
something of the population dynamics of these hosts.

SUMMARY

At our study site in southern Florida, most species of mutillids fly
through much of the year. With the exception of 2 species of Pseudo-
methoca, there is no evidence of phenological niche partitioning or
dependence on hosts that are only available for a short season. All abun-
dant species showed large population fluctuations during the 4-year
study period. We hope that our information will encourage publication
of similar data sets from other areas. We would like to think thatour work
is the first of a series of studies of geographic phenological variation in
mutillids, that can be interpreted in terms of evolutionary pressures exer-
ted by different climatic regimes.

TAXONOMIC DISTRIBUTION AND PHYLO-

GENETIC SIGNIFICANCE OF THE MALE

FORELEG HAIRPENCIL IN THE TORTRICINAE

(LEPIDOPTERA: TORTRICIDAE)'

John W. Brown^

ABSTRACT: I report for the first time male foreleg hairpencils in the tortricine tribes
Euliini, Schoenotenini, and Atteriini. The structures are identical in Euliini and Schoeno-
tenini, and their shared possession is considered a putative synapomorphy for these two
tribes. Although similar in structure and point of origin, the hairpencil in Atteriini lies
along the anterior longitudinal axis of the femur rather than along the outer base of the
coxa as in Euliini and Schoenotenini. The atteriine hairpencil may represent an indepen-
dently derived structure, or, more likely, a modification of that found in the other two
tribes.

Male secondary structures (e.g., costal fold, corema, hairpencil) are
common and diverse among exoporian and ditrysian Lepidoptera
(Varley 1962; Birch 1972, 1985). Although these structures may be strik-
ingly unique and almost certainly homologous among taxa sharing
them, their value in elucidating phylogenetic relationships is dimin-
ished by the fact that they are evolutionarily more labile than many other
adult morphological features. Shared possession of uniquely derived
male secondary structures provides compelling evidence of common
ancestry (Birth 1972; Varley 1962), but their absence may be meaningless
in a phylogenetic context since the correct position in the transformation
series (i.e., primitively absent - present - secondarily lost) may be impos-
sible to determine.

Few characters of the legs of tortricids have been studied on a com-
parative basis. Examples include the work of Falkovitch (1962) on male
secondary structures in Olethreutinae, and that of Yasuda (1972) on tar-
sal setae of Japanese Tortricinae. Horak ( 1984) concluded that legs pro-
vide fewcharacters useful in resolving phylogenetic relationships within
Tortricinae. However, my recent discovery of male foreleg hairpencils
among the tortricid tribes Euliini, Schoenotenini, and Atteriini may be
useful in demonstrating the monophyly of these taxa and in elucidating
relationships among their members.

sists of a fascicle of 15-25 slender, pale yellow, hairlike scales, that arise
together from the proximal end of the femur and extend along the outer
surface of the coxa to near its base (Figs. 1-3). Scales on the trochanter
and the distal portion of the coxa form a broad groove that partially con-
ceals the basal portion of the hairpencil. On the thorax near the base of
the coxa, there is an invaginated region and associated cuticular flap
which receives the distal ends of the hairpencil (Fig. 4). The function of
the hairpencil is unknown; presumably it plays a role in dissemination
of short-range courtship pheromones. Baker and Carde (1979a, 1979b)
and Baker, Nishida, and Roelofs (1981) have shown that male abdom-
inal androconia ofGrapholita (Olethreutinae), consisting of an eversible
membranous sac, are used to release a close-range female attractant.

Taxonomic distribution. The euliine/schoenotenine hairpencil has
a sporadic distribution throughout the two tribes (Tables 1 and 2); i.e. the
structure is present in 48% of euliine and 43% of schoenotenine genera
examined. In addition to those genera listed in Table 1, several under-
scribed euliine genera and many unplaced species of ""Eulia" Hiibner
possess the hairpencil. In some genera all species have the hairpencil; in
others it is absent and presumably secondarily lost in one or more
species. Its presence in the presumably most primitive as well as the more
derived genera of Euliini (Brown and Powell, in prep.) suggests that it
represents a synapomorphy uniting the Euliini and Schoenotenini rather
than a character derived numerous times within the two tribes.

The Euliini, as recently redefined by Powell (1986), previously was
considered a para- or polyphyletic assemblage of primarily Neotropical
genera, characterized by symplesiomorphies of male and female geni-
talia (Horak and Brown 1990). Possession of the hairpencil demon-
strates the common ancestry of genera that share this unique structure;
however, absence of the hairpencil among several taxa does not neces-
sarily exclude them from the tribe since it may have been lost secon-
darily. The structure is absent in more than half of the genera included
by Powell (1986) in the Euliini; on the basis of this and other characters, a
few of these genera likely are assigned incorrectly to this tribe (e.g.,
Ecnomiomorpha Obraztsov, Deltobathra Meyrick).

Hairpencil in Atteriini

Structure. In Atteriini, the hairpencil typically consists of a dense
brush of > 50 fine, flattened, setalike scales, arising along a narrow patch
on the anterior edge of the femur immediately distad of the junction with
the trochanter. The scales are shorter in relation to coxa length, more
flattened, and greater in number than those in Euliini and Schoeno-
tenini. When not displayed, the hairpencil lies along the longitudinal

axis of the femur, extending approximately to the distal end of the femur
(Fig. 5).

Taxonomic distribution. The foreleg hairpencil is present in seven
of eight described atteriine genera; it is absent in the monotypic Holop-
tygma Powell which is the only atteriine with a costal fold. It is absent in
one or more species of six of the seven genera (Table 3).

The monophyly of the Atteriini is convincingly demonstrated by the
modified "corethrogyne" scales on sterna VI and VII of the female and
the correlated oviposition behavior (Powell 1986). The corethryogyne
scaling is evidently absent in Sisurcana Powell where no unequivocal
association of males and females is known (Powell 1986). The unique
hairpencil provides further evidence for the monophyly of the Atteriini,
as well as confirming the membership of Sisurcana.

CONCLUSIONS

Two types of male foreleg hairpencils are found in the Tortricinae,
one type in Euliini and Schoenotenini, and the other in Atteriini. The
hairpencils are similar in structure, configuration, and point of origin.
Consequently, the shared presence of these structures may be inter-
preted as evidence of the common ancestry of these tribes.

Males of an undescribed genus that possess convincing atteriine
genitalia [i.e. "Philedone" aluminias (Meyrick) and "P."" citrochyta (Mey-
rick)], have typical euliine/schoenotenine hairpencils. It is possible that
the genus represents an early branch of Atteriini (before the develop-
ment of the atteriine hairpencil), and that the atteriine hairpencil repre-
sents a modification of that found in the Euliini and Schoenotenini. If
this interpretation is correct, the character supports relationships unsus-
pected by previous workers attempting to reconstruct tortricoid phylogeny.

ACALYPTRATE DIPTERA REARED FROM
HIGHER FUNGI IN NORTHEASTERN OHIO 1

Britt Bunyard, B.A. Foote 2

ABSTRACT: Living fungi were collected from two sites in northeastern Ohio between the
fall of 1987 and fall of 1988. Flies reared from this material in the laboratory were deter-
mined to species.

Fourteen species of acalyptrate Diptera, comprising five families and eight genera, were
reared from 44 species (14 families) of higher fungi. Among flies reared was Leiomyza
laevigata [Asteiidae]. No descriptions of the immature stages of any of the over 100 species
of Asteiidae worldwide are available. Also reared was Drosophilaguttifera [Drosophilidae],
another species whose biology is poorly known.

Most mycetophagous Diptera appeared to be generalists with respect to utilization of
fungal species. Larvae of several species were probably scavengers, utilizing decaying
fungal material.

Aside from a few publications (Buxton, 1960; Pielou. 1966; Pielou
andMathewman, 1966; Pielou and Verma, 1968;Shorrocks. 1973; Valley.
el /., 1 969), the study of mycetophagous Diptera associated with mush-
rooms remains in a pioneer stage (Graves and Graves, 1985).

The purpose of this study was to determine the species of acalyptrate
Diptera associated with higher fungi in northeastern Ohio (Portage Co.).
Generalizations about the trophic relationships of certain Diptera to
their fungal hosts (strict mycophagy, polyphagy, saprophagy) are also
given.

MATERIALS AND METHODS

Two sites in Portage Co. were chosen for the collection of fungi: Towner's
Woods near Kent and West Branch State Park near Ravenna.

Material was collected between September of 1987 and September of
1988. Each collected fungus was placed in a plastic bag or wrapped in
wax paper to prevent larvae of one mushroom from entering another.
Fungi were then identified using various sources (Graham, 1944; Lin-
coff, 1 98 1 ). To avoid incidental occurrences of Diptera with the fungi (e.g.
resting or hiding in crevices), only adults which actually emerged from
larvae occurring within the fungus were counted.

Upon emergence, adult Diptera were retained alive for at least 24
hours to allow the exoskeleton to harden and then killed and preserved.
Adults were either pinned or placed directly into 70% ethanol. Larvae

were killed in boiling water and then preserved in 70% ethanol. Preser-
ved specimens were placed in the Kent State University collection of
Diptera.

Rearing required the construction of special containers which allowed
the fungi to remain in a somewhat natural condition. The bottom of
these rearing chambers consisted of the bottom of petri dishes (10 x
100mm) to which had been added moistened pulverized peat moss. It
was necessary to keep the peat moss substrate in contact with the fungus
initially and to moisten it frequently to prevent desiccation. As the
fungus decayed, the substrate absorbed moisture produced by the fungus.
The remainder of the rearing container consisted of clear plastic tubing
having a diameter of 90mm and cut to various lengths. To the top of this
was glued fine polyester mesh material. The rearing chamber was placed
over the fungus in the petri dish. The fungal material was retained in the
rearing containers for at least three months.

Leiomyza laevigata Meigen [Asteiidae] has been reared from fungi
previously (Buxton, 1960; Sahrosky, 1957). The family Asteiidae is a
small one of some 100 species of which little is known. No descriptions of
the immature stages of any species of Asteiidae are available.

Gaurax atripalpus Sabrosky [Chloropidae] has been reared pre-
viously from Fames sp., [Polyporaceae] (Valley, etal., 1969). It is apparent
from this and our more recent rearings that G. atripalpus utilizes the fungi
as both a food source and site of overwintering.

The rearing of Athyroglossa granulosa Cresson [Ephydridae] from

fungi is surprising, because members of this family usually have larvae

that are aquatic or semiaquatic. Grimaldi and Jaenike (1983) reared

adults from larvae feeding in decaying skunk cabbage, Symplocarpus

foetidus (L.) Nutt.

There are many known species of fungivorous Drosophilidae. Droso-
phila falleni Wheeler, D. putrida Sturtevant, D. testacea von Roser, D.
tripunctata Loew, and Mycodrosophila dimidiata Loew, which were all
reared in this study, are all well known fungal feeders (Jaenike. 1977.
1978; Jaenike, et al., 1983; Patterson and Stone, 1952). However, none is
known to be monophagous (Jaenike, 1978; Lacy, 1984). Drosophila dun-
cani Sturtevant and D. guttifera Walker are also known to be fungal
feeders but little is known about the life history of either species (Patter-
son and Stone, 1952).

Two drosophilids, D. falleni and D. putrida, were reared from toxic
species ofAmanita mushrooms. These two as well as a few other species
have been reared in the past (Jaenike, 1977; Jaenike, et at., 1983) from
mushrooms containing toxic amanitins. The amanitins are alkaloid
compounds which are potent inhibitors of RNA polymerase II, the
enzyme which transcribes genes that encode messenger RNA's ( Wieland.
1968). Therefore, these compounds are potentially toxic to all eukar-
yotes. How these drosophilids manage to avoid being affected deleter-
iously is not known (Jaenike et al., 1983).

An interesting question raised by this study concerns how so many
different acalyptrate species, sometimes of the same genus, can coexist in
the same substrate (Table 1 )? As many as six species were found in the
same fungal sporophore at the same time. When examined more closely
it was apparent that in most cases larvae of the different species were
feeding on the same material, at the same time, and in a similar manner
(i.e. burrowing through the fungal sporophore). Apparently, competitive
exclusion is not a factor here, as the fungal food probably was not a limit-
ing resource. However, Grimaldi and Jaenike (1984), demonstrated that
mycophagous larvae frequently do exhaust the food available in indi-
vidual mushrooms. It is probable that predators or parasites of these lar-

120

ENTOMOLOGICAL NEWS

vae functioned to reduce competition (both inter - and intraspecific)
between larvae. Many parasitic wasps were obtained from many of the
fungi surveyed.

Another point made evident by this study as well as earlier one (Bux-
ton, 1960) is that certain fungi are more attractive to species of Diptera
than other fungi. For example, Pluteus cervinus Fr. [Pluteaceae] pos-
sessed the greatest diversity of acalyptrate species (Table. 1 ). In contrast,
several species of fungi were repeatedly examined, but no species of
acalyptrate Diptera were obtained. The reasons for this are unclear and
further research in this area is necessary. A final point to be made by this
study concerns the mechanisms utilized by the many species of fungi-
vorous Diptera to cope with the fact that fungal sporophores represent
an ephemeral and unpredictable food source. The months of May and
September produced the highest number of species of emerging adults
(Fig. 1). Many species of Diptera probably initiate a reproductive
diapause during times of no larval food sources, such as the dry summer
months. Other species may utilize other food sources, including live,
injured, and decaying vegetation. An example is Drosophila gutlifera
[Drosophilidae], a rare species that was believed to be strictly myco-
phagous (Patterson and Stone, 1952). However, we discovered that this
species, at least in laboratory rearings, readily accepted other substrates
(tomato juice, agar, bananas, commercial Drosophila medium) as an
ovipositional site and larval food source (Bunyard and Foote, 1990).
Similar results have been obtained in laboratory rearings of other
mycetophagous species of the guinaria group of Drosophila (Grimaldi,

fungi sources have been reported for these species, and the laboratory
results thus may not reflect reality.

EVOLUTION OF EUPHILOTES BIOTYPES: TRIALS AND TRIBULATIONS

OF THE BUTTERFLY BLUES

By Dr. Gordon F. Pratt

Darwin's book. The Origin of Species, changed the way we view ourselves and the world
around us; nevertheless, the origin of species remains a central concern of evolutionary
biologists. Because insects represent the great majority of known species, they are often the
subject of studies on speciation. Dr. Gordon F. Pratt, now a post doctoral associate at the
University of Delaware, is interested in insect speciation. While he was a graduate student
in California he studied a fascinating complex of blue butterflies of the genus Euphilotes
whose larvae feed exclusively on the blossoms and seeds of one or another of the species of
wild buckwheat, Eriogonum.

Variation in altitude, soil type, and climate in the southwestern United States have
created habitat islands suitable for the growth of Eriogonum and in turn Euphilotes. The
tight coupling between the flowering of particular host species and the butterfly's life cycle
has resulted in many local races that are behaviorly distinct. For example, some emerge in
the spring and others in the fall. Some adults fly near the ground where the flowers of their
food plant are, while others fly higher for flowers of a different species. The sister species
Euphilotes enoptes and E. battoides have sharp differences in male and female genitalia;
however, electrophoretic analysis of allozymes in various host races show they are closely
related. These studies also indicate that host races are evolving rapidly and suggest that E.
battoides evolved from the E. enoptes host race that feeds on Eriogonum umbellatum.

The adults of Euphilotes obtain nectar from the same plants on which they lay their eggs.
The larvae are cryptic and assimilate pigments from the flowers on which they feed. They
are attended by ants. Pupation occurs in the ground beneath the host plant. Presumably, in
desert environments where moisture triggers seed germination or growth of perennial
species, moisture also serves to synchronize adult emergence with blossoming. The fact
that pupae can survive up to five years in the laboratory helps to explain the absence of
adults in dry years and their reappearance several years later. The ability of the butterfly to
evolve different local populations adapted to specific host plants has resulted in sympatric
populations of a single species that do not interbreed.

Dr. Pratt's talk at the Philadelphia Academy of Natural Sciences drew one of the largest
audiences for a membership meeting in five years. Eighteen members and twelve guests
were present. Like Dr. Pratt's talk, the notes of local entomological interest focused on the
Lepidoptera and speciation. Dr. Chuck Mason reported that both the E and Z pheromone
races of the European corn borer, Ostrinia nubilalis, are common in Delaware. The E-type
emerges early and produces offspring that feed on a variety of early host plants other than
corn. The other type produces the Z isomer of the pheromone, emerges later, and attacks
corn in its first generation. The second generation of both types reproduce on corn. Hybrid
individuals produce a mixture of the pheromones. Dr. Duke Eisner noted a possibly
related situation of cranberry truilworm.Acrobasis vaccinii. Attempts to attract males with a
pheromone extracted from theconspecific race feeding on blueberry have been unsuccess-
ful. Dr. Ken Frank noted that female cecropia moths, Hyalophora cecropia, that emerge in
captivity later than their wild counterparts will sometimes attract males of the introduced
cynthia silkmoth, Sam/a ov7f/;/a, which normally emerge later than cecropia in the wild. At
the end of the meeting Dr. Frank distributed a number of cecropia coccoons he had res-
cued from a city site likely to be destroyed before summer.

IMPROVED CULTURE TECHNIQUES FOR MASS
REARING GALLERIA MELLONELLA (LEPIDOP-

TERA: PYRALIDAE) 1

Frank A. Eischen , Alfred Dietz J

ABSTRACT: Supplementing an artificial diet with 5% pollen, honey, or beeswax signifi-
cantly increased survival of adult Galleria mellonella. Survival on the basic diet averaged
27.4%. When honey, pollen, or wax was added, survival was 44.7%. 80.8%. and 89.6%. respec-
tively. Developmental time for moths fed diets containing 5% pollen or a combination of
pollen, honey, and wax was shorter by approximately 2-5 days. Newly emerged virgin
females which had fed as larvae on a 100% pollen, honey, and wax diet weighed 36% more
than females derived from larvae fed the artifical diet. A phagostimulatory hypothesis
is suggested.

Additionally, 78% of prepupae accepted cut plastic soda straws as puparial sites and
spun their cocoons in them. This greatly facilitated the handling of individual prepupae
and pupae and should be a convenience to both research programs and commercial wax
moth producers.

The greater wax moth, Galleria mellonella(\~.), is easily reared and is
often used as a laboratory animal. However, our initial attempts to
establish a culture from wild stock resulted in low survival rates (ca. 30%)
when an artificial diet [Stoneville( SV) developed by King etal. 1979] was
used. However, pilot studies indicated that survival was good (ca. 95%)
on a diet composed wholly of their naturally occurring larval food, i.e.
pollen, honey, and beeswax. Inspection of the artificial diet (King el al.
1979) did not reveal nutritional shortcomings. Previous studies have
shown that small amounts of beeswax improved growth rates (Beck
1960, Dadd 1966, Young 1964). Further, Dadd (1966) observed higher
survival rates during portions of larval development when beeswax was
added to an artificial diet. These findings suggested that small amounts
of natural food could play an important nutritional role in adult sur-
vival. We report here the results of a study done to determine why sur-
vival differed so strikingly on artificial diet compared with a diet com-

The Stoneville diet consists largely of baby foods (Gerber mixed and
high protein cereals), gycerol, wheat germ, water, sucrose, and vitamins
(see Kingetat. 1 979 for details). Its protein composition is about 13%. The
pollen-honey-wax diet was made by mixing bee-collected pollen (63%;
see Dietz 1982 for plant species represented) with chipped honey comb
(37%). The honeycomb (cappings) contained approximately 50% honey.
The protein content of this diet is estimated to be about 13%. Twenty
grams of diet were placed in 100ml glass rearing jars, sealed and kept
frozen until used. Fortified diets were prepared by placing 19gofSVdiet
in the rearing jar, and then Ig of either pollen, honey, or wax was sprink-
led or dripped onto its surface.

Moths were obtained by removing overwintering prepupae from a
dead honey bee hive in Athens, Georgia. They were incubated at 30C.
Adults emerged in about two weeks and mated inter se. Eggs were collected
between strips of pleated wax paper. Three days after laying, egg masses
were divided into small clusters of 1 0- 1 5 eggs. These clusters were placed
on filter paper in petri dishes and incubated at 30C + 2C. Just before
hatching, eggs were examined and clusters containing at least 10 larvae
that appeared normal were selected for testing. Excess larvae were des-
troyed by puncturing the eggs with a needle. Eggs were then placed in
small aluminum foil baskets ( 16mm x 10mm) and randomly assigned to
diets. Twenty replications of each diet were performed. After addition of
the eggs, the rearing jars were sealed with a solid metal screw lid contain-
ing a rubber interseal. Rearing jars were held at 32C + 1 C, 40 + 10%
RH, and 12:12LD. Seven days after infestation, egg clusters were re-
moved and percent hatch determined. Also, the solid lids were replaced
with a similar lid containing a 9mm hole. This hole was covered with a
piece of transparent tape, sticky side out. Several small holes were
punched in the tape with a small pin to allow air exchange. When the
first prepupae were observed, this tape was replaced with a circular piece
of aluminum screen. At this stage, rearing jars were inspected daily. As
adults appeared they were removed, sexed, and their emergence date
noted. The first twenty adult virgin females that emerged from the SV
and the pollen-honey-wax diets were weighed. Sixty days from the time
of egg laying, the contents of the rearing jars were examined. Cocoons
were counted and pupal mortality noted.

Survival and emergence data were analyzed with a 1-way ANOVA,
and differences among treatments evaluated with Duncan's multiple
range test. Student's t-test was used to determine differences in adult
female weights.

To confirm that the supplemented Stoneville diet was suitable for a
mass rearing program, we fed the Stoneville+5% fresh frozen pollen to
ca. 6,000 hatching G. mellonella larvae (eggs were weighed, not counted).

Vol. 101, No. 2. March & April 1990 125

As prepupae emerged from the diet and began spinning light cocoons,
they were removed and placed in 3.81 glass jars containing cut plastic
soda straws (2 X 0.5cm; Sweetheart R ). About 70 prepupae were added to
jars containing 200-300% excess of cut straws (scattered horizonally on
the bottom of the jar), which were covered with a single circular piece of
toweling. Jars were kept in a darkened incubator (same conditions as in
above dietary trials).

RESULTS

The addition of 5% of either pollen, honey, or beeswax (PHW) to the
Stoneville(SV) diet resulted in a significant increase in adult survival
(Table 1 ). Adult survival on the basic diet averaged 27.4%. The addition of
honey increased survival to 44.7% (P < 0.05). Fortification with either
pollen, wax, or a combination of pollen, honey, and wax produced sur-
vival rates that did not differ significantly from the control diet (89.2%).

Males reared on the SV+5% pollen, SV+PHW, and control diet
eclosed in a significantly shorter time (ca. 3-5 days, P < 0.05) than moths
on the other three diets (Table 1). Average time to first emergence was
slightly shorter for males (0.2-1 .3 days) than that required by females, but
this difference was not significant. Newly emerged virgin females weighed
on average less when reared on the SV diet, than on the control diet ( 1 14
and 156mg, respectively; P < 0.001). During the mass rearing trial 78% of
prepupae spun their cocoon inside the cut soda straws. The adult sur-
vival rate for larvae fed the Stoneville+5% pollen diet during this trial
was estimated to be about 84%.

DISCUSSION

The striking increases in survival caused by small amounts of pollen,
honey, or beeswax was not the result of an altered physical consistency,
nor the addition of essential nutrients (Haydak 1936. 1940. Allegret 1964;
Dadd 1966; Marston and Campbell 1973). Dadd (1966) suggested that
the inclusion of beeswax served as a source of metabolic water. However,
the basic Stoneville diet contains about 17% water and supports good lar-
val growth (King etal. 1979). The 300% increase in survival with the addi-
tion of 5% beeswax to this diet suggests that beeswax performed an
additional function.

Eischen et al. (unpublished) found in a preliminary test that newly
hatched larvae preferentially chose artificial diets to which alcoholic
extract of pollen was added. This suggests that pollen provided phago-
stimuli attractive to G. mellonella. Other observations support this view.
Balazs (1958) reported that newly hatched larvae preferred honeycomb

126 ENTOMOLOGICAL NEWS

to an artificial diet, even though this diet contained honey and beeswax.
He also noted that older larvae fed the same artificial diet chose hon-
eycomb when given the opportunity. Haydak (1936) reported that larvae
attacked old combs in those areas that contained pollen. We have on
numerous occasions observed newly hatched larvae that have been
given the Stoneville diet wander about the inner walls of their rearing
container when food was nearby. Newly hatched larvae given a honey-
pollen-wax diet were rarely seen away from the food. The natural history
of this moth also lends support to a phagostimulatory hypothesis. Adult
females oviposit in and around bee colonies; generally in crevices where
eggs are protected from the bees (Paddock 1918, Nielsen and Brister
1977). Once hatched, the larvae must search for food. Though distances
may be short, it would be adaptive to be able to locate food (which also
serves as shelter) rapidly in the hostile interior of a honey bee colony.

The shorter times to eclosion of moths fed diets containing pollen
indicate that even small amounts of pollen are effective in promoting
development. Since pollen was localized on the upper surface of the diet
mass, it seems unlikely that its consumption would have been uniformly
distributed during larval growth. If the phagostimulatory hypothesis is
true, then consumption and consequent beneficial effects occured dur-
ing the earliest instars. From this it follows that an early pollen meal may
supply a nutrient, perhaps protein, that allows faster development, while
apparently wax and honey do not.

Prepupal acceptance of soda straws greatly facilitated the handling
of prepupae and pupae. Large numbers of known age groups can be held
in relatively small containers. This is convenient when storing prepupae
under refrigerated conditions (ca. 15.5C). We find that chilled, lightly
spun prepupae are easy to use by fishermen, a slight squeeze on the straw
prompts the prepupae to crawl out. Because male prepupae emerged
from the diet slightly before females, the first harvest of prepupae results
in a high percentage of males. This is an added benefit when separation
of sexes is desired. Since these tests, we have successfully reared many
thousand G. mellonella using this technique.

These findings should be of value to those who wish to preserve the
genetic variation observed in wild stock or to increase the yield of G.
mellonella in newly-established cultures (Bush 1975). However, cultures
that have been reared for many generations on a particular artificial diet
and consequently undergone selection for it may not show greatly im-
proved survival. Nevertheless, under some conditions it could be pru-
dent as well as cost effective to supplement artificial wax moth diets with
small amounts of properly stored pollen or unprocessed honeycomb.

NEW HOST RECORD FOR ANISOTOMA BASALIS

(COLEOPTERA: LEIODIDAE) BREEDING IN
SPOROCARPS OF THE SLIME MOLD LYCOGALA
FLAVOFUSCUM (MYXOMYCETES: LICEALES) 1

Quentin D. Wheeler, E. Richard Hoebeke 2

ABSTRACT: Two breeding populations of the primitive staphylinoid beetle Anisotoma
basalis (Leiodidae: Agathidiini) were found feeding within mature aethalial sporocarps of
the uncommon slime mold Lycogala jlavofuscum (Myxomycetes: Liceales) on the campus
of Cornell University, Ithaca, New York, in 1983 and 1989. These discoveries represent the
first documented insect association for this myxomycete.

An emerging pattern of host utilization in the agathidiine Leiodidae
suggests that many species of these beetles are able to breed on a diverse
range of host Myxomycetes (slime molds). Few instances of host specificity
are suspected to date. The majority of species have only been associated
with mature sporocarps (Blackwell 1984; Lawence, 1989; Lawrence &
Newton, 1980; Newton, 1984; Wheeler, 1979), although a few records
exist for both Anisotoma (Russell, 1979; Wheeler, 1980) and Agathidium
(Newton, 1984; Wheeler, 1984a, 1984b, 1987) on plasmodia of host slime
molds. Many records involve common myxomycetes that produce large
fruiting bodies [e.g., Fuligo septica (L.) Wiggers] or dense masses of
smaller fruiting bodies [e.g., Stemonitis fusca Roth]. The slime mold
Lycogala epidendrum (L.) Fries, a small, puffball-like species, has also
been recorded as an agathidiine host (Lawrence & Newton, 1 980; Black-
well, 1984).

Myxomycete host records have been reported by Lawrence & New-
ton (1980), based on label data, field observations and from published
accounts in the North American literature, for eight North American
Anisotoma, including slime mold species of the genera Comatrichia,
Fuligo, Lycogala, Metatrichia, Stemonitis, Trichia and Tubifera. Precise
information on feeding habits and preferences, and microhabitats of the
majority of leiodid beetles is scarce.

In this paper we provide evidence for a new adult and larval host
record for Anisotoma basalis (LeConte) (Leiodidae: Agathidiini). Two
breeding populations of this primitive staphylinoid beetle were found
feeding within mature aethalial sporocarps of the uncommon slime
mold Lycogala Jlavofuscum (Ehrenb.) Rost. These populations were dis-
covered by one of us ( ERH) on two separate occasions, one on a prostrate
log and the other on a standing dead tree, along a wooded hillside on the

Cornell University campus, Ithaca, New York (Tompkins Co.). These
discoveries represent the first documented insect association for this
myxomycete.

On 4 June 1983, a large sporocarp of L.flavofuscum (approx. 5.1 x 4.6
cm.) (Fig. 1) was found on the surface of a prostrate log (Fig. 2) along a
wooded slope on the campus of Cornell University. Within this mature
fruiting body a massive population of both larvae and adults ofAnisotoma
basalis was discovered. This population was observed and sampled for
more than a week. Because we only partially disturbed the fruiting body,
no complete census of the beetles was made. However, more than 200 lar-
vae were collected and slide-mounted, and more than that number were
collected into ethanol. We estimate that the total number of adult A.
basalis was at least 100-200 and that the number of larvae probably
exceeded 400-500.

cm.) was discovered on the trunk of a standing, dead basswood tree
(Tilia), approximately 5 ft. above the ground. It, like the previous sporo-
carp, had also been penetrated by adult specimens of A. basalts (Fig. 3),
but no larval specimens were observed.

Both sporocarps are deposited in the Cornell University Insect Col-
lection as voucher specimens of the slime mold.

All three larval instars associated with adult A. basalts from this
myxomycete host have been described by Wheeler (1990a), as the basis
for a study on ontogeny (Wheeler, 1990b).

ANTENNAL ANOMALY IN OXYPODA OPACA

(COLEOPTERA: STAPHYLINIDAE)

FROM NEW YORK 1

E. Richard Hoebeke 2

ABSTRACT: A specimen ot Oxypoda opaca, collected in Tompkins Co., NY, in June 1988,
was found to exhibit a teratological aberration of its left antenna, whereby the distal anten-
nomeres (articles III-XI) are compressed into a short club-like structure. This aberration is
illustrated by scanning electron microscopy, and compared with appendage anomalies
previously recorded in other Oxypoda species.

Instances of teratology (i.e., individuals exhibiting structural abnor-
malities) are not uncommon in many species of beetles (Coleoptera),
especially among artificially reared specimens (Crowson, 198 1). Teratol-
ogical malformations have been studied and categorized for the Coleop-
tera in the monographic works of Balazuc (1948, 1969).

Among members of the family Staphylinidae, the phenomenon of
teratology was reviewed in some detail by Frank (1981) who chronicled
all recorded morphological aberrations, including the presence of
supernumerary appendages, fusion or loss of appendages, anomalies of
body segmentation and malformations of the thorax and male genitalia.
Recently, Segers (1987) reported a case of triophthalmy and other teratol-
ogical aberrations in the Staphylinidae, anomalies previously unreported
for the family.

Because of a paucity of published information on teratological speci-
mens in the largest of the staphylinid subfamilies, the Aleocharinae, it
seems advisable to report on morphological abnormalities exhibited in
specimens taken under natural conditions. Therefore, in this note I
document a teratological specimen of the aleocharine Oxypoda opaca
(Gravenhorst), a Palearctic species recently reported for the first time
from North America (Hoebeke, 1989). This teratology, an antennal
malformation, is thoroughly described and further illustrated with scan-
ning electron photomicrographs. Additional literature on teratologies in
members of the genus Oxypoda is summarized.

A single New York specimen was found to have an extreme aberra-
tion of the left antenna, a type of meiomely (following the classification
and terminology of Balazuc, 1948). The antenna is 3-segmented; anten-
nomeres III-XI are apparently compactly fused, resulting in a clubbed
structure with no apparent segmentation (Figs. 1-3). The basal article
(scape) is somewhat stouter than that of the normal antenna, but article

II appears to be of nearly normal dimensions. Visible at high magnifica-
tion (540x), there are two large, craterlike structures, perhaps thermo- or
hygroreceptors, in juxtaposition on the dorsal surface (Fig. 3). In addi-
tion to being strongly setose, the surface of the "club" is covered with mic-
rosculpture consisting of an imbricate network of distinct microlines.
The overall length of the abnormal left antenna is 0.48 mm, compared to
1.17 mm for the normal right antenna.

The normal 1 1-segmented, right antenna is characterized as follows:
basal article (scape) and articles II and III elongated; articles IV-X sub-
quadrate to feebly transverse and not increasing much in length; and ter-
minal article (XI) elongate, pointed apically and equal to or slightly
longer than articles IX+X combined. The terminal article of the normal
antenna bears a pair of rather small, inconspicuous coeloconica-type
sensilla, probably thermo- or hygrosensitive in function. One sensillum
is located on the dorsal surface (Fig. 4, arrow) while the other occurs on
the opposite (ventral) side.

It is not possible to ascribe the antennal aberration described above
to any genetic mechanism (mutational) or to any other external factor
(i.e., extreme environmental conditions, injury, etc.) acting on an earlier
developmental stage such as the pupa.

Although the pair of sensilla on the apical segment of the normal
antenna (Fig. 4, minute, coeloconica-type, dorsal/ventral in position) are
very different from the pair of "sensilla-like" structures on the deformed
antenna (Fig. 3, extremely large, crater-like, dorsal/dorsal in position), I
surmise that these structures are probably homologous. Thus, it is the
author's opinion that the deformed antenna does indeed represent an
entire antenna and not a partial one, with the loss of intermediate or
apical segments.

The coated specimen is deposited in the Cornell University Insect
Collection. Complete collection data are as follows: NY: Tompkins Co.,
Town of Ulysses, N. of Jacksonville, 22 June 1988, E. R. Hoebeke. (male).

A search of the literature reveals 3 other references to teratology of
appendages in Oxypoda. Uhmann (1919) reported a specimen of O.
opaca, found near Dresden (E. Germany), with an abnormal right an-
tenna. The distal antennomeres, beyond article V, were shorter in length
and more compressed than the analogous articles of the normal left
antenna. Segmentation, however, was still evident in the abnormal an-
tenna. Keys (1936) documented a specimen of 0. opaca from New Forest
(S. England) with "four segments only to each of its anterior tarsi, where-
by its tarsal formula was 4-5-5 instead of the 5-5-5 which is proper to the
genus." Segers (1987) presented a case of symphysomely (the left antenna
showing 2 partly fused articles) in a normal female of O. brachyptera
(Stephens) collected from a pasture at Poeke (Belgium, 6-5-1982, trapped
in pitfalls).

This is the second of two volumes dealing with the frugivorous Tephritidae. It is divided

specific ("ie. Cytoplasmic Incompatibility in Rhagoletis Cerasi") to the general (ie. "Life
History Strategies of Tephritid Fruit Flies"). The graphics are well presented and the book
attractively designed.

In addition to scope this volume has depth. The abundance of organized references
alone is invaluable to anyone used to dealing with the cosmopolitan and often scattered
fruit fly literature. Within minutes of opening the book, I had found interesting but
unfamiliar data and papers. However, the reader should be warned that there was con-
siderable delay between the writing of many of these chapters and publication so that there
are fewer recent citations than the 1989 publication date would suggest.

With that caveat excepted, I believe this book would be an important reference to any-
one with an interest in fruit flies. This includes not only those who are directly involved
with fruit fly control but also those interested in the more "basic" endeavors of Ecology,
Behavior, etc. I, for one, already find myself referring to one or the other of these volumes

A NEW SPECIES AND NEW RECORD OF THE

WATER-PENNY GENUS PSEPHENOPS

(COLEOPTERA: PSEPHENIDAE)

FROM COSTA RICA 1

Paul J. Spangler 2

ABSTRACT: Members of the genus Psephenops have not been recorded previously from
Costa Rica. A new species, Psephenops prestonae. from Costa Rica is described and com-
pared to Psephenops maculicollis Darlington (1936) described from Colombia and here
reported from Costa Rica. A diagnosis of Psephenops maculicollis is given and the distinc-
tive aedeagus of each species is illustrated.

The aquatic larvae of water-penny beetles are usually common
throughout the year in shallow streams with sand, gravel, and rocky sub-
strates and a moderately fast velocity. The riparian adult psephenids,
however, are short lived, elusive, and not commonly collected, especially
not in series. Consequently, a number of species of water-penny beetles
have been described from one or only a few adult specimens, as is this
new species. The single male of Psephenops prestonae, n. sp., was collected
by Warren E. Steiner and companions J.M. Hill & S.E. Frye.

I collected seven specimens of Psephenops maculicollis Darlington
( 1 936) in San Isidro, Costa Rica, in 1 967 but have not previously reported
on them.

These are the first species of water-penny beetles known from Costa
Rica and bring the number of water-pennies known from middle America
to eight.

NEW RECORD AND RANGE EXTENSION FOR

RHYACOPHILA WALLOWA (TRICHOPTERA:

RHYACOPHILIDAE) FROM ROCKY MOUNTAIN

NATIONAL PARK, COLORADO 1

Scott J. Herrmann

ABSTRACT: Rhyacophila wallowa is reported for the first time from Colorado. This record
represents a southeastern extension of the known range of the species. Current state dis-
tribution records of/?, wallowa include OR, CA, WA, MT, ID, WY, UT and CO.

Three adult males of Rhyacophila wallowa Denning were collected in
Rocky Mountain National Park (RMNP), Larimer County, Colorado,
on 3 August 1984. The specific collection site in RMNP was at the con-
fluence of Fall River and Chiquita Creek at an altitude of 2640 m amsl
(8660 ft amsl) in T5N, R74W, Sll on the east side of the Continental
Divide. The three adults were collected by the author with a standard
sweep net at sunset. This is the first reported record of R. wallowa
from Colorado.

Denning's (1956) holotype male was collected 15 July 1949 from the
Wallowa River, Wallowa County, Oregon. Anderson (1976) and Wold
(1974) reported several other Oregon sites in addition to some from
Washington, Idaho, northern California and northern Wyoming.
Wold's (1974) Wyoming record is a single metamorphotype male collected
from the Gardner River, Yellowstone National Park, 12 July 1961.
Baumann and Unzicker ( 198 1 ) included R. wallowa in their checklist of
Trichoptera of Utah, as did Newell and Potter (1973) and Roemhild
(1982) of Montana. In Montana Roemhild (1982) commonly found this
species in cold alpine streams east and west of the Continental Divide.
The first published record from Colorado represents a southeastern
extension of the known range of R. wallowa: it also represents the six-
teenth species of Rhyacophila to be reported from Colorado (Herrmann.
Ruiter and Unzicker 1986). Other species of Trichoptera collected simul-
taneously with R. wallowa at the Fall River (RMNP) site included: Rhya-
cophila hyalinata Banks, Rhyacophila harmstoni Ross, Ecclisomyia
maculosa Banks, Oligophlebodes minuta (Banks), Onocosmoecus unicolor
(Banks), Agrypnia deflata (Milne) and Hydropsyche oslari Banks. Ruiter
and Lavigne (1985) stated that little is known about the habits of this
species. At the RMNP collection site Fall River is classified as a cold,
lower montane, second-order stream and Chiquita Creek as a cold.

HPLABEL: A PROGRAM AND MICROFONT FOR

THE GENERATION OF DATE/LOCALITY LABELS

USING A LASER PRINTER 1

D. Christopher Darling 2 , R. C. Plowright 3

ABSTRACT: A computer program for the direct generation of date/locality labels for
pinned insect specimens is described. These labels are compared with those produced by
offset printing and by reduced photocopying.

One of the major bottlenecks in the curation of insect collections is
the generation of date/locality labels for specimens. For pinned and
pointed specimens, these labels have to be small (approximately 25
characters per inch), permanent, and legible. Most insect collections
now use a two-step process to produce labels. First, labels are printed
either with a typewriter or a printer in a standard font (usually 10-12
characters/inch) and a paste-up board is assembled. A "stat" is prepared
by photographically reducing the board to produce a master of the
required size when the paste-up board is filled. Labels are then offset
printed onto high quality paper (i.e. high rag content, acid neutralized).
These labels are of excellent quality (Fig. Id) but labels cannot be
efficiently generated until a paste-up board is filled, which can result in a
delay of many months in the preparation of the final labels. Some collec-
tions produce labels only 2 or 3 times a year. In addition, offset printing
usually has a minimum run of at least 50 copies per original, resulting in
many wasted labels for small lots of specimens.

These constraints on the efficient generation of date/locality labels
have no doubt resulted in the loss of a great deal of valuable ecological
and distribution data. Very general labels are often used, giving only a
minimum of information, e.g. U.S.A., OR: Benton Co., June 1988, D.C.
Darling. Often much more detailed information is contained in field
notes, but these data often fail to become associated with specimens
because of inefficiencies in label production, and are ultimately lost.
One solution is to produce "generic" labels for collecting localities and to
add a second label with more specific ecological information, such as
floral associations, hosts, or collecting method. There are at least two
problems with this approach: double labelling is time consuming and
affords an additional opportunity for mislabelling; and insect speci-

mens can quickly become cluttered with labels.

Many collections and collectors have experimented with producing
date/locality labels with reducing photocopy machines. When printed
on high quality paper these labels have the required permanence and
can be produced quickly, but usually with considerable wastage of
paper. Two reductions of 64% are necessary to produce labels of the cor-
rect size and the final labels lack the clarity of offset printed labels (Fig.
lb,c). These labels are generally regarded as unacceptable by major
museums as a standard curatorial procedure.

Computer programs that have been published for generating insect
labels on a microcomputer are either very basic (Kissinger 1982) or
primarly concerned with the mechanics of generating multiple copies of
labels and storing and managing files of labels (Ellis et al. 1985). These
programs streamline the production of output suitable for assembling
paste-up boards but do not generate labels directly. Labels must still be
reduced for offset printing or with a photocopy machine.

Laser printing technology is ideally suited to the production of labels

for pinned or pointed specimens. The printing process results in extremely
high quality labels which should have excellent long term permanence
under normal storage conditions. There is, however, some concern about
the permanence of laser printed labels for specimens stored in alcohol or
when labels are exposed to various reagents and high temperatures [see
Insect Collection News, 2(2):26-27 (1989)]. Microcomputers and laser
printers (LaserJet series II) are quickly becoming a standard feature of
most museum and university departments. Unfortunately, the smallest
available fonts (6 point) are too large to directly generate date/locality
labels (Fig. la). Alternatively, commercially-available desktop publish-
ing programs are available to generate labels directly. These tend to be
rather cumbersome, requiring considerable word processing skills, and
cannot be incorporated easily into programs for generating multiple
copies of individual labels. For example, Fancy Font can generate high
quality 3 point labels. We present here an edited microfont and computer
program (HPLABEL) for the direct production of date/locality labels
using an IBM-PC (or compatible) microcomputer and Hewlett-Packard
LaserJet Series II printer.

The microfont is an edited version of a public domain font supplied
to us by Henry Spencer (Department of Zoology, University of Toronto).
A BASIC program was written by CP to streamline the generation of
labels. The program uses either BASICA or GWBASIC and prompts the
user for up to 5 lines of label data. After previewing the label, the user is
asked how many copies of the label are required. The program then
prompts for additional labels. The labels are stored in a buffer and printed
to efficiently use label paper.

Figure 1 compares labels produced by HPLABEL (Fig. le) with stan-
dard labels generated by offset printing (Fig. Id) and with labels generated
by a reducing photocopy machine (Fig. le). Although not as sharp as
offset printing, we think that the HPLABELS are acceptable for the
routine labelling of specimens. These labels are clearly superior to those
produced by a 40% reduction of either 10 point (Fig. Ib) or 6-point fonts
(Fig. le). With these reduced labels the letters run together making the
labels difficult to read and the labels are either too large (Fig. Ib) or too
small and illegible (Fig. le).

This program is currently being used for label production in the
Department of Entomology, Royal Ontario Museum. A copy of the font,
program and operating instructions is available by sending a formatted
5.25 inch diskette to DCD.

of high quality. Comprehensive lists of references follow each chapter. Slight deficiencies
in coverage of North American papers are more than compensated for by the inclusion of
European papers that are rarely seen here.

The series title implies that these large-format (8 1/2" x 12") books may only be of
interest to economic entomologists. However, a broad range of subjects, by a large number

The sample (Vol. 2C) that I received contains up-to-date reviews and syntheses of the
vast world literature. The scope and depth are most ambitious. The cost is not as high as it
appears because the large format includes approximately 30% more information per page

MICROCYLLOEPUS FORMICOIDEUS

(COLEOPTERA: ELMIDAE), A NEW RIFFLE

BEETLE FROM DEATH VALLEY NATIONAL

MONUMENT, CALIFORNIA*

William D. Shepard 2

ABSTRACT: Microcylloepus formicoideus sp. nov. is described from Travertine Springs,
Inyo Co., California. A survey of local permanent springs indicates that the species only
exists at the type locality. Relationships with other congeners is discussed.

Microcylloepus was erected in 1935 by Hinton for the sole species
Stenelmis pusillus LeConte. Since then, 24 other species have been added
to the genus (Brown 198 1 ). Microcylloepus is essentially a Neotropical ele-
ment that has invaded the Nearctic. Within the US occur five described
species and perhaps several undescribed species. The eastern M. pusillus
has had four subspecies described but they represent only color morphs.
Populations have been found that have all the morphs co-occuring. In
the western Nearctic several species have been taken, particularly from
warm springs in the Basin and Range desert. Also in the western US
occurs M. similis Hinton which has long been considered to be a sub-
species of M pusillus. Although it resembles M. pusillus in many aspects,
it is a valid species, as is seen with a side-to-side comparison and when
examining the genitalia.

In the course of a survey of the riffle beetles of Death Valley two new
species were discovered. One is described here; the second presents a
more complicated problem requiring more analysis and will be des-
cribed later.

DIAGNOSIS

M. formicoideus is readily distinguished from all other North and
Central American congeners by its small size and relatively long legs
(these characters give the ant-like appearance that suggested its name).
Also very diagnostic is the lack of distinct elytral humeri, a result of
brachyptery (H. P. Brown, pers. comm.). This character is shared with M.
angustus Hinton from Mexico (Hinton 1940). The latter is somewhat
larger and possesses a distinctly different aedeagus. The male genitalia
of M formicoideus have parameres resembling those of M thermarum
Darlington while the median lobe is similar to that of M. inaequalis
(Sharp) and M. moapus La Rivers. However, the genital characters in-
volve subtle differences and Hinton (1940) notes that " a number of
species may have the structure of the male genitalia identical."

TYPE LOCALITY

The type locality is: CA, Inyo Co., Death Valley National Monument
(DVNM), 2.5 miles (4 km) east of Death Valley (along US Highway 190),
Travertine Spring. The spring heads are numerous and their outflows
combine while flowing southward toward the highway. Upon reaching
the highway all flow is channeled into a concrete-lined canal that crosses
under the highway and parallels it westward toward Furnace Creek Inn,
the local hotel. M. formicoideus occurs in the spring heads and along the
stream course almost to the road. Initially M. formicoideus occurs alone in
the springhead but it is eventually replaced along the stream course by
another congener.

An extensive survey of other DVNM water sources showed this to be
the only locality where M. formicoideus occurs. The benthic community
along the spring outflows is remarkably diverse and may represent the
most diverse aquatic insect fauna in DVNM. This area and community
certainly deserve protection and preservation. Texas Spring (which is
closer to the hotel, campgrounds, date-palm orchard and visitors' center)
has been completely diverted to human water uses. Whatever com-
munity was there is now lost. Because of the proximity of the two springs,
and the great likelihood that their outflows were contiguous, their com-
munities were probably the same. Thus the benthic community in Traver-
tine Spring probably represents the only remaining portion of a much
larger community.

TYPES

Holotype male, allotype female and 37 para types collected 23/1/1984
by WDS from Furnace Creek canal, a concrete canal diverting water to
Furnance Creek Wash from Travertine Springs. Additional paratypes
from the type locality include 53 collected by WDS on 16/IV/1984, 134
collected by Hugh Leech on 25/XII/1962, and 26 collected by Raymond
Bandar on 25/XII/1962. The holotype, allotype and several paratypes
will be deposited in the National Museum of Natural History at the
Smithsonian Institution. Additional paratypes will be deposited in the
collections of Harley P. Brown (Norman, OK), Louisiana State Univer-
sity (Baton Rouge, LA), William D. Shepard (Sacramento, CA), Death
Valley National Monument museum (Death Valley, CA), the California
Department of Food and Agriculture (Sacramento, CA) and Monte L.
Bean Museum at Brigham Young University (Provo, UT). The Leech
and Bander paratypes are in the collection of the California Academy of
Sciences (San Francisco, CA).

ETYMOLOGY

The name M. formicoideus is chosen to note the slender body and long
legs which give individuals an ant-like appearance.

DISCUSSION

In Brown (1972) this species keys to couplet #70 which separates M.
browni (Hatch) from M. moapus. M. formicoideus can be distinguished
from M. browni by its smaller length and width. M. formicoideus can be
distinguished from M. moapus by several characters: smaller size; black
versus brown dorsal color; elytra with more pronounced carinae and
punctae, surface more asperate and less shiny; anterior portion of pros-
ternum more strongly directed ventrally. In Hinton's (1940) work on
Mexican e\mids,M. formicoideus keys to M angustus from which it can be
distinguished by several characters: general surface densely granulate;
longer carina on third intervals; sides of prosternal process not parallel;
metasternal carinae strongly divergent; first abdominal sternite with
carinae parallel posteriorly.

M. thermarum is a closely related species from which Microcylloepus
formicoideus varies in its more pronounced elytral sculpturing. In A/, ther-
marum the third elytral intervals are only slightly prominent, the fifth
intervals are flat Lnd the seventh intervals have "fine, inconspicuous cos-
tae" (Darlington 1928).

152 ENTOMOLOGICAL NEWS

This new species, with its putative close relationship with M. moapus,
M. thermarum, and M. angustus, recalls La Rivers' (1949) prediction of
intervening forms indicating all to be just intergrading populations of
one species. While close examination reveals character differences equi-
valent to those between other species oiMicrocylloepus, one is led to won-
der about the effects of the similar habitats in which these species live.
Hinton (1940) doesn't mention the habitat forM angustus, but all the rest
come from warm springs. The relatively uniform warm temperatures
may well alter developmental pathways leaving morphological varia-
tion canalized. Sweeney (1984) indicates that higher tempertures may
maximize larval developmental rates leading to smaller than normal
adults. Another species inhabiting warm springs in the Owens Valley of
California has lost temporal synchronization of pupation (WDS, un-
published data). Alternatively, one may assume that this species group
represents a different lineage from that including M. pusillus, which
exists throughout the eastern half of the US. The genus is sorely in need
of revision. Only then can questions of the source of variation in Microcyl-
loepus be properly answered.

SOCIETY MEETING OF MARCH 28, 1990

EVOLUTION AND HYBRIDIZATION OF ADMIRAL BUTTERFLIES

Dr. Austin P. Platt, Speaker

Insect taxonomists beware! If all groups are as interesting and complex as the butterfly
genus Limenitis, most disputes between lumpers and splitters may never be resolved. Only
in recent years, more than a century after the principal morphological types were de-
scribed, has a reasonable understanding of the relationships among admiral butterflies
emerged. As Nobelist Arthur Kornberg once said, "I have yet to see a complicated problem
which, when looked at in the right way, doesn't become more complicated."

Dr. Austin P. Platt of the University of Maryland, Baltimore County, has studied the
genetics and speciation of admiral butterflies for more than two decades. These well known
and widely distributed butterflies include the viceroy, Limenitis archippus; the banded pur-
ple, L. arthemis arthemis; the red-spotted purple, L. a. astyanax; Weidemeyer's admiral, L.
weidemeyerii; and Lorquin's admiral, L. lorquini. The latter four are really allopatric races of
a single "super species" which, except for arthemis and styanax, rarely hybridize in the wild.
Subspecies of the viceroy, L. a. archippus and L. a.floridensis, are mimics respectively of the
monarch, Danaus plexippus, and the queen, D. gilippus. Similarly the red-spotted purple
and Lorquin's admiral are thought to be mimics of the pipevine swallowtail. Bonus
philenor, and the California sister, Adelpha bredowii. Based on cladistic analyses and con-
siderations of geographical distribution, all mimetic forms of Limenitis are probably
derived from an ancestral form resembling the northern banded purple.

The banded phenotype is widespread in related genera and is controlled by a single
autosomal gene. Genetic analyses of natural and laboratory hybrids between various
species and subspecies of Limenitis indicate that several genes modify the banding pattern.
Dr. Platt offered the intriguing hypothesis that the distinctive nonmimetic transvese black
band on the hind wing of the monarch-like viceroy represents the vestige of a dark-
margined white band that has collapsed as the result of modifying genes. The plausibility
of this hypothesis was strengthened by comparing the wing patterns of hybrids between the
viceroy and each of the members of the L. arthemis super species group that were displayed
by Dr. Platt (See Bull. Ent. Soc. Am. (1983) 29(3): 10 - 20).

In addition to a discussion of the evolutionary relationships within Limenitis, Dr. Platt
discussed their interesting life cycle. The eggs are commonly laid on willow or aspen leaves.
They look like minature geodesic domes. The larvae that hatch from them- establish
characteristic feeding stations. In response to photoperiod, halfgrown 3rd instar larvae
accumulate glycerol as a natural antifreeze and retreat to hibernacula in which they over-
winter. These leaf-enclosed structures are easy to recognize and can be collected for pop-
ulation studies.

Dr. Plan's talk at the University of Delaware was attended by seventeen members and
four guests.

THE STATUS OF PISON DOGGONUM
(HYMENOPTERA: SPHECIDAE) 1

Arnold S. Menke 2

ABSTRACT: Pison doggonum, originally described from Mexico, is a member of the wes-
tern Pacific island fauna and may be a synonym of P. iridipenne.

Pison doggonum Menke was described in 1988 from a single female
specimen labelled simply "Mejico, Mus. Drews." It now appears that the
holotype had erroneous locality data. Recently while examining some
Pison from islands in the western Pacific Ocean I noted that specimens of
P. iridipenne Smith looked similar to doggonum. Pison iridipenne occurs in
Hawaii, Fiji, Samoa, Society Islands, Tuamotu Archipelago, Bolabola
Is., Marquesas, Bismarck Archipelago, and islands in Micronesia
(Krombein, 1949, Bohart and Menke, 1976, Tsuneki, 1982). I borrowed
the holotype of doggonum from the Zoologisk Museum in Copenhagen,
and compared it with material of iridipenne identified by Karl Krombein.
The two taxa appear identical and doggonum may be a junior synonym,
although Krombein (1949) suggests that iridipenne is possibly a complex
of species in which the males offer the best differences. For that reason I
think it would be premature to synonymize doggonum with iridipenne. In
any event, diggonum should be considered as a member of the western
Pacific insular fauna, and not the Neotropical Region.

The discovery just related underscores the fact that describing new
species from single, ancient specimens with meagre locality data is a
risky, unwise business.

DISTRIBUTIONAL NOTES ON NORTH AND

CENTRAL AMERICAN DILARIDAE

(NEUROPTERA) 1 ' 2

Kevin M. Hoffman^

ABSTRACT: Nallachius americanus is recorded from South Carolina and central Georgia
and a male of Nallachius pulchellus is reported from Costa Rica. An emendation is made to
the existing key for New World Dilaridae to accomodate the presence of a forked costal
crossvein in each forewing of the N. pulchellus specimen.

The sixteen species of New World Dilaridae are rarely-collected
neuropterans of which only three are known from North and Central
America (Adams 1979, Penny \98\). Nallachius americanus (McLachlan)
has been recorded from Puerto Rico, Venezuela, and the eastern United
States (the District of Columbia, Florida, Georgia, Indiana, Kentucky,
Maryland, Michigan, Pennsylvania, Texas and Virginia) (Gurney 1947,
MacLeod and Spiegler 1961, Adams 1970, Lawson and McCafferty
1984); Nallachius championi (Navas) is known from only one locality in
Guatemala (Adams 1970); and Nallachius pulchellus (Banks) has been
recorded from Cuba and the southwestern United States (Arizona)
(Alayo 1968, Adams 1970). The present paper records N. americanus from
South Carolina and central Georgia, N. pulchellus from Costa Rica, and

This record represents the first dilarid reported from Costa Rica and
confirms the prediction of Adams (1970) that this species would event-
ually be found in Central America. The specimen was identified by com-
paring the genitalia both with the description and figures of Adams
(1970) and with the cleared genitalia of the holotype in the Museum of
Comparative Zoology (MCZ), Harvard University. However, a problem
was encountered when using the key of Adams (1970) because the second
character used to distinguish N. pulchellus in couplet 6 is "costal veinlets
simple," and each forewing of the Costa Rican specimen has a distinctly
forked costal crossvein at half length. Furthermore, this crossvein is in
approximately the same location as a forked costal crossvein figured by
Alayo(1968, Fig. 10B) fora male TV. pulchellus from Cuba. In view of the
variation in this character, the phrase "costal veinlets simple" should be
deleted from couplet 6 in the key by Adams ( 1 970) and from couplet 8a in
the key by Penny (1981), which was modified from the key by Adams.
These deletions will not affect the second halves of these couplets and
will actually alleviate some confusion, because costal veinlets were not
used as characters in the second halves.

BOOK REVIEW

THE ANTS. Bert Holldobler and Edward O. Wilson. 1990. Belknap
Press of Harvard University. 732 pp. $65.

CONTENTS: Introduction; Classification (139 pp.) including keys, illustrations of world
genera; Colony formation and structure (36 pp.); Behavior (s.l.) (338 pp.); Communities ( 1 7
pp.); Symbiosis (120 pp.); Specialized predators, fungus growers, and harvesters (50 pp.);
Weaver ants (1 1 pp.); Study methods (4 pp.); Glossary, bibliography, index (83 pp.)

This is an overwhelming narrative of the lives of ants, crammed with facts and ideas
and glorious illustrations. There is no way that I can comment on specific facts and theories
in this book; there are simply too many of them, and one cannot review an elephant by
critically examining a few hairs. Suffice it to say that if you are a biologist you must have
this book for the sheer excitement of its brilliantly detailed revelation of a bizarre and
somehow symbolic world, like one of the busier visions of Hieronymus Bosch. If you are a
myrmecologist you will just have to get used to lugging around a 7-lb. volume, because it
will be difficult to study, or even think about ants, without this book at hand.

In an age of books that are edited hodgepodges of disparate authors, THE ANTS is uni-
que in both its exhaustive coverage and its cohesion. I wish I could say it was a practical
model for scientific writing, but the fact is that few of us are up to such a tour de force. Any-
body who has attempted to meld information from a dozen references into a succinct and
literate paragraph knows the difficulty of such a task; Holldobler and Wilson do this,
apparently effortlessly, for hundreds of pages, utilizing thousands of different references.
Enormous numbers of studies are briefly described, with the inclusion of exactly the
primary data one might need to draw one's own conclusion, even though the authors have
supplied their personal interpretations. In other words, the authors, experts though they
are, write for an audience presumed to have its own initiative and powers of deduction In
another eschewal of arrogance, the authors avoid sarcastic treatment or unceremonious
dumping of the less plausible theories that circulate through myrmecology. Throughout
the book there is an emphasis on fascinating unanswered questions, thereby providing
both foundation and direction for future work.

To write such a book, one must, at least temporarily, deliver oneself over to obsession.
Thus, though "communites" of ants and ant-plant symbioses are carefully analyzed, there
is relatively little coverage of the role of ants in entire ecological communities, and almost
an avoidance of the dreadful topic of ants as the principle fodder of a host of other animals,
including many vertebrates. The limitations of sociality are hardly explored, so after read-
ing the book one might wonder how there can be more than a million species of arthropods
not apotheosized into sociality. Still, it is an obsession that is never tedious, always creative.
Even the statement (Chapt. ) ) that humans and ants represent the summits of evolution in
vertebrates and arthropods respectively, manages to create a rather endearing new hybrid
bias: antopocentrism.

To see this book is to covet it, and the price is modest. THE ANTS is destined to become as
widely distributed as its extraordinary subjects.

FIRST UNITED STATES RECORD OF
ASCALOBYAS (NEUROPTERA: ASCALAPHIDAE),
A RANGE EXTENSION FROM NORTHEASTERN

MEXICO TO TEXAS 1

Roy C. Vogtsberger

ABSTRACT: A female specimen of Ascalobyas albistigma (Neuroptera: Ascalaphidae),
collected west of Juno in August, 1 973 from Val Verde Co., Texas, was discovered in the Mid-
western State University (Texas) insect collection. This is the first record of this genus in the
United States and extends its known range by approximately 575 miles (925 km.).

While identifying the Neuroptera in the Midwestern State University
insect collection, the author discovered a very large and peculiar owlfly
in the collection. The specimen was collected west of Juno in Val Verde
Co., Texas in August, 1973 by H. L. Horry, graduate biology student. The
specimen was probably caught with an aerial net, since the habitat on the
collection label read "air".

The Texas specimen was readily assigned to the ascalaphid sub-
family Haplogleniinae, since the eyes were entire and not divided by a
transverse sulcus. According to the literature, Ascaloptynx (or Neurop-
teryx) had previously been the only members of this subfamily known to
occur in the United States. The distinguishing feature of this genus in the
New World, besides the entire eyes, is the petiolate wings, with forewings
having a prominent thumb-like projection on the posterior margin near
the base of each wing. Penny (1981) placed Ascaloptynx in the tribe
Verticillecerini.

Since the specimen in question lacks petiolate wings and the promi-
nent thumb-like projections, it is assigned to the tribe Haplogleniini.
Penny ( 1 98 1 ) recognized three genera of American Haplogleniini: Amoea,
Ascalobyas, and Haploglenius. The Texas specimen was assigned io Asca-
lobyas on the basis of the antennae being shorter than half the length of
the forewing, costal field of forewing and apical fourth of all wings being
dark brown, and the yellowish-white pterostigmas. Penny ( 1 98 1 ) presented
Ascalobyas as a new genus because the old genus name, Byas Rambur,
1842 was preoccupied.

Weele's (1908) monograph with descriptions of the two known species
of Byas (= Ascalobyas) mentions the type species, microcerus Rambur, as
an eastern and Antillean species and a western species, albistigma
(Walker). He suggested they could be combined under one species,

because the terminalia are superficially quite similar, and the extremely
small differences are never constant. However, he chose to maintain
them as two distinct species due to lack of transitional forms from the
intermediate region of the two species' distributions. Measurements of
the Texas specimen (Table 1) and color descriptions most nearly coin-
cide with those given by Weele (1908) for the western albistigma, which
would be logical for a Texas locality.

The northernmost published record for Ascalobyas albistigma
(Walker), 1853 is San Pedro Sula, Honduras (Weele, 1908). Penny (1981)
reported that "Ascalobyas is presently known from two species ranging
from northern Brazil to Panama," but mapped the distribution of Ascalo-
byas to extend northward to San Pedro Sula, Honduras. The statement,
therefore, was probably an error and should have read, ". . .from northern
Brazil to Honduras". This makes the Texas specimen a 1343 mile (2161
km.) range extension from the northernmost published record for the
species.

Oliver Flint (pers. comm., 1989), curator of Neuropteroids at the
National Museum of Natural History, Smithsonian Institution, reports
several examples of the species from well into northeastern Mexico in
the NMNH collection. The northernmost specimens are from El Salto
Falls on the San Luis Potosi-Tamaulipas border near El Naranjo and,
previous to the Texas specimen, were considered to represent the northern
range extent for the genus. Therefore, the Val Verde record is a northern
range extension of 'Ascalobyas albistigma by approximately 575 miles (925
km.) from El Salto Falls in northeastern Mexico to Val Verde Co., Texas, a
new record for the United States. The owlfly, damaged in transit to the
Smithsonian Institution as a dried specimen to be compared with the
Mexican specimens, has been relaxed and is nowpreserved in alcohol in
the Midwestern State University insect collection.

SOCIETY MEETING OF APRIL 25, 1990

PATTERNS IN NATURE
Dr. Richard Weber, Speaker

Dr. Richard Weber, entomologist from the University of Delaware and eminent insect
photographer, treated his audience of 21 members and 30 guests to a unique experience.
Not only did he show them remarkable pictures of insects but he also regaled them with his
world view, quick wit, and playful humor. While many seek to learn and emulate Dick
Weber's technical skills, it was evident that technique, though important, was peripheral to
the real essence of his photography. Pretty pictures come to life when they tell a story or pro-
voke a question. As Albert Szent-Gygorgyi said, "See what others have seen, but think what
no one has ever thought." Dick Weber's success comes from photographing what he
thinks.

It was not possible to be passive in the audience because questions, banter, and repartee
were part of the show. "What's going on here? What good are cryptic or aposematic colora-
tion against night predators? Does anyone know the name of this plant? Has anybody seen
this? Can you imagine the smell I put up with photographing maggots on that rabbit car-
cass? Did you ever see a bird dropping that looked like an insect? Look at that, a fly eating a
wasp!" These were part of the barrage of illustrated, thought-provoking comments and
anecdotes from an evening that was memorable for other reasons as well.

Prior to Dr. Weber's talk. President Roger Fuester presented the annual Calvert Prize to
Jennifer Reynolds for her science fair project, "Does the color of light affect the reproduc-
tion of Drosophila melanogasterl" She and the first and second runners up, Kimberly
Wallace and Chaitanya Rao, displayed their insect-related projects. Margot Livingston,
the first Calvert Prize recipient in 1987, was present for the ceremony.

In addition to the Calvert Prize, special certificates of appreciation were presented to
unsuspecting members of the Society for their great commitment and continuing con-
tributions to the Society. Howard P. Boyd, president from 1977-1981 and editor of Entomo-
logical News since 1974, described his association with AES as one of the most rewarding
and enjoyable activities of his life. Mildred Morgan, office secretary since 1979, also
received a certificate of appreciation. She confided that she almost quit after three weeks
but that Howard Boyd convinced her to stick it out a "bit longer." Both expressed their
heartfelt thanks to the Society for the honor. Jesse Freese, treasurer since 1969, was also
honored but was unable to attend the meeting.

BIOLOGICAL NOTES ON DROSOPHILA

GUTTIFERA (DIPTERA: DROSOPHILIDAE),

A CONSUMER OF MUSHROOMS 1

Britt Bunyard, B. A. Foote 2

ABSTRACT: Information is given on the life history and larval feeding habits ofDrosophila
guttifera, a species previously considered to be strictly mycophagous. Laboratory rearings
indicate that larvae of this species can be polyphagous.

Patterson and Stone (1952) listed Drosophila guttifera Walker, a wide
ranging species in the eastern and midwestern states, as "being so rare as
to have nothing known about its life cycle." However, they felt that it was
probably mycophagous.

The purposes of the present study were to elucidate the life history of
D. guttifera, describe its larval feeding habits, and to determine whether
the species is truly mycophagous.

MATERIALS AND METHODS

Adult flies were reared from larvae occurring in sporophores of gill-
bearing mushrooms collected in an old field that is part of the Kent State
University campus in Portage County, Ohio. Sporophores were placed
in breeding containers containing a layer of moistened peat moss to
allow emergence of adults. To establish a laboratory colony, adults
emerging from the field-collected mushrooms were transferred to breed-
ing jars containing pieces of the commercial mushroom Agaricus bis-
porus Singer. Adults emerging from commercial mushrooms were then
placed in vials containing Instant Drosophila Medium (Carolina Bio-
logical Supply) and allowed to cycle. Subsequent rearings utilized such
"unnatural" foods as decaying lettuce, bananas, and tomato juice.

We determined oviposition preference by offering females different
food substrates and recording the number of eggs deposited on each sub-
strate. For this study, an isoline was developed by allowing a virgin
female to mate with only one male. All adults used in the preference tests
were of this isoline reared on Instant Drosophila Medium.

The substrate was nutrient agar to which was added (while still
liquid) homogenized aliquots of four different food sources: commercial
mushroom, iceberg lettuce, tomato juice, and banana. Each of the liquid
mixtures of food and agar was poured into a sterile petri plate and

allowed to solidify. The ratio of sustrate to agar was 10: 1 as measured by
volume. Plates of pure agar were also poured to the same heights as those
with food. Once solidified, four 2.0 cm diameter discs were cut from each
of the agar plates. A disc taken from each of the food/agar plates were
placed in holes of corresponding diameter and depth in the plain agar
plates. As a control, discs of pure agar were used. Ten gravid, non-
anesthetized females were then added to all test plates and allowed to
oviposit for 24 hrs. at 27 C. Adults were then removed, and the number
of eggs occuring on each substrate counted. Each test was replicated five
times. Females were not used in subsequent tests.
Voucher specimens have been deposited in AMNH and USNM.

RESULTS AND DISCUSSION

Adults of D. guttifera, were reared only from sporophores oiCollybia
dryophila (Bull, ex Fr.) Kummer (Tricholomataceae) and Psilocybe poly-
trichophila Pk. (Strophariaceae) out of 44 different species of field-collected
mushrooms held in emergence chambers (Bunyard and Foote, 1990).
Life history data obtained for flies reared on Instant Drosophila Medium
are given in Table 1.

Adult flies were successfully reared from all four food substrates as
well as from plain agar on which a culture of baker's yeast was actively
growing. In contrast, all larvae placed on pure agar died before form-
ing puparia.

Tests to determine preference of oviposition site (Table 2) showed
mushrooms to be the preferred food substrate. The lettuce substrate was
also frequently selected, but the banana and tomato juice substrates were
poorly utilized.

The laboratory rearings, particularly the frequent use of rotting let-
tuce as an ovipositional site, lead us to suggest that D. guttifera, may be
capable of utilizing decaying plant material in nature and thus is not
necessarily restricted to a fungal diet. Of course, countering that sugges-
tion is the fact that adults have only been reared under natural con-
ditions from larvae feeding in mushrooms.

In notes of local entomological interest Dr. Paul Schaefer followed up on a discussion
at the November meeting. He showed a number of photographs by Dwight Kuhn of Dex-
ter, Maine showing Polistes wasps that had been parasitized by the strepsipteran, Xenospec-
kii. Few in the audience had ever seen a strepsipteran, let alone pictures of the fleeting,
free-living adult male mating with the grub-like parasitic female still within the abdomen
of the host wasp! We all came away realizing that this odd insect is more common than first
thought and no doubt paper wasps will be examined more closely this summer as a
result.

PROPYLEA QUATUORDECIMPUNCTATA:
ADDITIONAL U. S. RECORDS OF AN

ADVENTIVE LADY BEETLE
(COLEOPTERA: COCCINELLIDAE) 1

A. G. Wheeler, Jr. 2

ABSTRACT: The distribution of Propylea quatuordecimpunctata, an Old World aphido-
phagous coccinellid known in North America from Quebec, New York, and Vermont, is
extended to Maine. Occurrence of this adventive predator is attributed to spread of pop-
ulations along the St. Lawrence River in Quebec rather than to intentional releases for
biocontrol purposes. The native and exotic plants on which P. quatuordecimpunctata was
collected in Maine and at an additional site in Vermont are listed; probable aphid prey
are noted.

The Palearctic coccinellid Propylea quatuordecimpunctata (L.) feeds
on numerous European aphid species associated with diverse crops and
habitats. Evaluated in Oklahoma for its biocontrol potential against the
greenbug, Schizaphis graminum (Rondani) (Rogers et al. 1972 a,b), it was
released in Delaware, New Jersey, and Oklahoma beginning in 1970.
Attempts to establish this predator were unsuccessful (Gordon 1985,
Dysart 1988).

At about the time that P. quatuordecimpunctata was imported from
France by the U. S. Department of Agriculture (Rogers et al. 1971), an
established population was detected in North America during 1968 near
Ste. Foy, Quebec (Chantal 1972). Its fortuitous introduction into eastern
Canada thus predated intentional releases in the United States.

Subsequent collections in Quebec, mostly along the St. Lawrence
River, led Larochelle and Lariviere (1980) to suggest that it had been
introduced with ship traffic associated with the St. Lawrence Seaway.
Dysart (1988) and Schaefer and Dysart (1988) concurred that this coc-
cinellid probably was accidentally introduced into the New World. By
1987, P. quatuordecimpunctata had been collected in 14 counties in Quebec,
Chittenden and Grand Isle counties in northern Vermont, and at Platts-
burgh (Clinton County) in northeastern New York (Dysart 1988). Gor-
don's (1985) diagnosis and illustration of the adult facilitate recognition
of this distinctive species in the Nearctic fauna.

Larochelle and Lariviere (1980) and Dysart ( 1 988) suggested that this
aphidophagous coccinellid, having adapted to Quebec's harsh climate,
probably will spread throughout most of North America. Herein, I
extend the known Nearctic distribution to Maine, cite an additional Ver-

specimens have been deposited in the insect collections of Cornell
University, Ithaca, New York (CUIC), and Pennsylvania Department of

Propylea quatuordecimpunctata: Additional U.S. Records

On 11 June 1988, 1 collected seven adults on the University of Ver-
mont campus at Burlington, Chittenden County. Two were beaten from
terminals of tatarian honeysuckle, Lonicem tatarica L., infested with the
aphid Hyadaphis tataricae (Aizenberg); five were collected from an orna-
mental cinquefoil, Potentilla parvifolia Lehm.

In 1989, 1 swept four adults on 3 July from hairy vetch, Vicia villosa
Roth, along Old Coldbrook road near exit 44 of 1-95 at Hampden
(Penobscot County), Maine. The most likely prey species on vetch was
the pea aphid, Acyrthosiphon pisum (Harris). Two days later an adult was
collected in Houlton (Aroostook County), Maine, by beating branches
of speckled alder, Alnusrugosa (DuRoi) Spreng., infested with the woolly
alder aphid, Paraprociphilus tessellatus (Fitch).

R. V. Flanders called my attention to a previous Maine record, one
not formally published but cited in the National Pest Happenings news-
letter [5 (3): 4, 1989], issued by the Texas Agricultural Extension Service.
One adult was collected 7 June 1988 on raspberry at Monmouth (Ken-
nebec County), by M. P. Tully.

DISCUSSION

Schaefer and Dysart (1988) noted that P. quatuordecimpunctata is
being propagated and redistributed by the USDA APHIS Biological
Control Program. No recoveries, however, have been made from any of
the release sites, including those in Maryland and Pennsylvania (P. W.
Schaefer, personal communication) and North Falmouth, Massachu-
setts (R. V. Flanders, personal communication). The Maine records
probably can be attributed to natural dispersal of the well-established
Quebec populations rather than to intentional releases or to a separate
introduction with European commerce. The Penobscot County collec-
tion near Bangor extends the known U. S. distribution about 350 km east
of the Plattsburgh, New York - Burlington, Vermont area. The Houlton
site in Aroostook County lies about 240 km from the nearest population
recorded in Quebec; Monmouth (Kennebec County) is about 230 km
from the nearest Quebec population.

ADDITIONS TO THE PAPILIONOIDEA

(LEPIDOPTERA) OF THE REVILLAGIGEDO

ISLANDS, MEXICO 1

John W. Brown 2

ABSTRACT: Five species of butterflies are reported from the Revillagigedo Islands, Mex-
ico, for the first time: Phoebis agarithe (Pieridae); Chlorostrymon simaethis, Leptotes marinus,
and Hemiargus ceraunus (Lycaenidae); and Danaus gilippus (Nymphalidae). These new
records increase to ten the number of Papilionoidea recorded from this archipelago.

The Revillagigedo Archipelago is comprised of four islands located
approximately 500 km SSWof Cabo San Lucas, Baja California Sur, and
about 600 km W of Cabo Corrientes, Jalisco. Politically, the islands
belong to the state of Colima, Mexico. The islands are oceanic and
volcanic in origin. Socorro is the largest and most diverse topographi-
cally; Clarion and San Benedicto are considerably smaller; and Roca
Partida is little more than a rock jutting from the sea (Palacios-Vargas,
Llampallas, and Hogue 1982).

Vazquez (1958, 1959, 1960) cited five butterfly taxa from the Revillag-
igedos, four of which represent endemic subspecies: Battus philenor
insularis (Vazq., \956)(Papi\ionidae), Strymon melinusclarionensis(Heid.,
1933) (Lycaenidae), Strymon columella clarionica (Vazq., 1958) (Lycae-
nidae), and Erynnisfuneralis(ScuddeT& Burgess, 1870)(Hesperiidae), all
from Clarion; and Strymon columella socorroica (Vazq., 1958) (Lycae-
nidae) from Socorro. Palacios-Vargas et al. (1982) added a sight record of
the widespread Neotropical Phoebis sennae (Linnaeus, 1758) (Pieridae)
from Socorro. The purpose of this note is to present the first records of
five additional species of Papilionoidea from Socorro Island, and the
first capture record of Phoebis sennae. All of these are widespread Neo-
tropical species that occur commonly on the Mexican mainland. Depos-
itories are abbreviated as follows: LACM, Natural History Museum of
Los Angeles County, Los Angeles, California; SDNHM, San Diego

Phoebis agarithe (Boisduval): Socorro Island, Bahia Braithwaite, 1M, 16 April 1987, D.

discal line of the ventral forewing (Brown 1929; Howe 1975). The single specimen is in poor
condition inhibiting subspecific assignment.

LYCAENIDAE

Chlorostrymon simaeihis (Drury): Socorro Island, 3200', 12F, 15 April 1955, E. Y. Dawson

H. hanno (Stoll). Intra-population variability in H. ceraunus inhibits meaningful use of
trinomials in this species.

NYMPHALIDAE

DISCUSSION

No butterfly species has been recorded from either San Benedicto or
Roca Partida. Of the ten species recorded from Socorro (n = 7) and
Clarion (n=4), it is surprising that only one is known from both islands,
i.e. Strymon columella, represented by an endemic subspecies on each
island. It is likely that the absence of additional taxa in common to both
islands reflects insufficient sampling rather than ecological equilibria.

This monographic revision of a blowfly genus whose larvae feed upon the blood of nest-
lings of many passerine birds in both enthralling and very informative. This is the third
revision of the genus in the last 60 years. In the last previous treatment of its included
species. Hall (1948. The Blowflies of North America. Thos. Say Foundation, p 179-201)
flatly declared that " Protocalliphora . . . does not occur in North America." The current
authors have painstakingly settled this matter. Although misidentified type specimens and
designated lectotypes have led to some confusion concerning the proper generic name.
North American usage and the current work will certainly establish Protocalliphora as the
correct generic name of the bird blowflies. Species in the genus possess a fascinating
biological association with birds, and their larvae have unique anatomical attributes to
facilitate their 'parasitic' mode of feeding. While Hall (1948) recognized 10 species, this
work recognizes 26 species, 15 of which are described as new, and 2 species that are now
known to be Holarctic in distribution, P. chrysorrhoea and P. braueri. Each species treated
here is given a complete description, including a diagnosis, description of male and female,
descriptions of the immature stages, particularly the puparium, the material examined,
with the type series for new species, distribution informatioin, and ecology and biology,
along with appropriate remarks. These descriptions present admirable models of what
every entomologist would desire to have in a revision. Unfortunately, larval cephalo-
pharyngeal skeletons and the prothoracic fringe of the mature larvae are not illustrated;
one must refer to Hall (1948, PL 38) for these details. Also, the details of the posterior
spiracles and the integumentary armature from the puparia are not easily resolved in the
halftone illustrations. Certainly, this work will be useful to entomologists, ornithologists,
ecologists, and field workers. After over 30 years of work, study, and compilation, the
authors have presented an excellent book.

INVERTEBRATE POPULATIONS IN THE NESTS

OF A SCREECH OWL (OTUS ASIO) AND AN

AMERICAN KESTREL (FALCO SPARVERIUS)

IN CENTRAL NEW YORK 1

James R. Philips , Daniel L. DindaP

ABSTRACT: Screech owl (Otus asio) nest material from a tree hole in Syracuse, N.Y., con-
tained 22,991 arthropods of 61 species. Arthropod density was 131/g dry weight of nest
material. An American Kestrel (Falco sparverius) nest in a nest box in Jamesville, N.Y.,
yielded 26,553 invertebrates of 93 species. Arthropod density was 38/g dry weight of nest
material. Lists of the species found and their populations are presented, and their trophic
and symbiotic relationships are discussed. Bird parasite levels were extremely low. Litter
fauna was dominant in the screech owl nest, while stored products fauna was dominant in
the Kestrel nest.

Nests of birds harbor a wide variety of invertebrates,, including soil
and litter, parasitic, predatory and coprophilic organisms. Numerous
studies have demonstrated that birds' nests are reservoirs of domestic
and stored products pests as well, containing populations of carpet
beetles (Dermestidae), clothes moths (Tineidae), house dust mites (Pyro-
glyphidae), stored products mites (Glycyphagidae), and poultry mites
(Macronyssidae) (Woodroffe and Southgate, 1951; Woodroffe, 1953,
1954; Baker et #/., 1956). Nests of birds of prey (Falconiformes and Strigi-
formes) serve as a habitat for necrophilic arthropods as well as other
nidicoles, since they contain carrion and regurgitated pellet remnants of
their prey (Philips and Dindal, 1977).

The check-lists of Hicks (1959, 1962, 1971) serve as excellent guides to
the literature on insects in birds nests, and they demonstrate how poorly
raptor nest fauna is known. Prior to this study, only six species of inver-
tebrates were known from eastern screech owl (Otus asio (L.)) nests
(Baker, 1904, Bequaert, 1955, Gehlbach and Baldridge, 1987; Linsley,
1944; Robinson, 1941; Vaurie 1955) and only eight species were known
from American kestrel (Falco sparverius L.) nests (Balgooyen, 1976,
Bequaert, 1955; Capelle and Whitworth, 1973; Hill and Work, 1947;
Roest, 1957; Williams, 1947). The objective of this study was to inves-
tigate the invertebrate community of a screech owl and a kestrel nest, and
to determine the levels of parasites, pest, and other species infestation
in them.

METHODS

Eastern screech owls occur in mixed woodlands east of the Rocky
Mountains, feeding on small vertebrates and invertebrates and roosting
and nesting in hardwood tree hollows or occasionally in nest boxes
(Hekstra, 1973; Karalus and Eckert, 1974). In 1975, screech owls were
observed nesting and roosting in a tree hole 9m high in a white oak
(Quercus alba L.) in Oakwood Cemetery, Syracuse, New York. On 12
March 1976, a 1 75 g dry wt. sample of nest material was collected from the
tree hole. At this time the hole was being used by the owls, but egg-laying
had not yet taken place. Most of the sample material was placed in mod-
ified Tullgren funnels (Murphy, 1962) for extraction of microarthropods,
and weighed when dry. The rest was placed in culture dishes so that
nidicolous insect larvae could be raised to adults for identification. On
16 June 1976, after nesting was over, a second small sample of nest
material was collected and used for invertebrate extraction. Although
the March sample removed most of the litter from the tree hole, it did not
ruin the hole as a nest site, since the owls nested there in 1976 and 1977 as
they had several years previously.

American kestrels inhabit open country in North and South America,
like the screech owl feeding on small vertebrates and invertebrates and
nesting in tree holes or nest boxes (Brown and Amadon, 1968). On 24
June 1976, the day after the nestlings fledged, we collected an American
kestrel nest (705 g dry wt.) in a nest box 5m high in a dead tree in James-
ville, New York. The nest material was processed in the same way as the
screech owl nest.

RESULTS

The March screech owl nest sample included as much of the nest
debris as could be obtained through the tree hole. The material consisted
mainly of bits of oak leaves and small twigs. Small amounts of grass,
woodchips, dirt, eggshell, excreta, feathers and pellet material (chitin,
hair and bones) were also present. Prey remains included a skull and jaw
of Microtus pennsylvanicus (Ord.). Funnel extraction yielded 22,991 mic-
roarthropods of 61 species (Table 1). Fifteen species of insects were
fqund, but 99% of the individuals were mites. Arthropod density was 1317
g dry wt. of nest; individual species and their populations are given in
Table 2.

The June screech owl postnesting sample containing basal material
from the nest hole was not analyzed in detail. A survey of the June nest
fauna revealed that almost all of the species present were also present in
the March sample. Relative populations were quite different, but that is

172 ENTOMOLOGICAL NEWS

probably more the result of the site disturbance in March - removing so
much of the litter in the hole - than the result of changes associated with
the nesting cycle. Two species were present in June that were not observed
in March - Dendrophaonia scabra G. -T. (Diptera: Muscidae) and Trox
variolatus Mels. (Coleoptera: Trogidae).

The American kestrel nest was composed mainly of sawdust with bits
of sticks, leaves, moss, grass, wood, excreta, chitinous prey remains, pel-
lets of hair, bone and chitin and several prey feet. Identifiable prey
remains included two skulls of Microtus pennsylvanicus (Ord.) and many
fragments of the carabid beetle Calosoma frigidum Kirby. One avian
skull was found, probably that of a sparrow. The nest sample contained
26,553 individuals of 93 species (Table 1). Thirty-one species of insects
were found, but 90% of the individuals were mites. Arthropod density
was 38/g dry wt; individual species and their populations are given in
Table 3.

BIOLOGICAL ANNOTATIONS ON COLLECTED TAXA

Screech Owl Nest Fauna

Ramusella clavipectinata (Mich.), the numerically dominant species
in this nest community, is a widespread oribatid mite fungivore which
Mahunka (1986) found to be very abundant in Hungary. Conditions in
the tree-hole full of highly decomposed leaf litter were near optimal for
this mite, judging by its tremendous population. The nest oribatids are
part of the humus fauna involved in the decomposition of the nest
material.

The astigmatic mites found included nest humus and animal remains
fauna, with several new genera and species (Fain and Philips, 1977a,
1977b, 1978a, 1979, 1981). Fuscarus was previously known only from
rodent nests, and nothing was known of its food habits (Krantz, 1978).
We observed fungal spores as gut contents of all stages of Fusacarus
tenuipes (Fain and Philips), and the fungus species was the same as that
eaten by Oppia and Acotyledon .

Acotyledon paradoxa Ouds. was previously known only from phoretic
deutonymphs and a protonymph. The discovery of all stages of this
species has enabled taxonomists to clarify the systematic position of the
genus. This species has been found on a bat and in granaries in the Soviet
Union, and in mouse nests in the U.S.A. (Fain and Philips, 1978c).

Histiogaster robustus Wdrg. is known from trees (Woodring, 1966b).
Other species in the genus have been found associated with bark beetles.

The histiostomatids collected were represented mainly by the ento-
mophilic nonfeeding hypopus stage. Development of this stage from
protonymphs may have been triggered by the extraction process. His-

Vol. 101, No. 3, May & June 1990 173

tiostomatids were not common in the nest leaf litter, but were abundant
in the basal hole debris of the postnesting sample. One species of Myi-
anoetus is known to be phoretic on Muscina stabulans (Fall.) ( Hughes and
Jackson, 1958). In the June sample we observed 20 Histiostoma paucipu-
teolum Fain and Philips hypopodes on the head, legs, and abdomen of a
Trox variolatus Mels. beetle larva. An adult T. variolatus carried 53 of these
hypopodes, almost all on the legs. In the March sample, one histerid bee-
tle adult oWendrophilusxavieri Mars, bore 20 of these hypopodes, mainly
on the elytra and abdomen. Feeding stages of histiostomatid mites
generally strain microorganisms from wet substrates (Krantz, 1978).

Besides Histiostoma hypopodes, the adult trogid beetle carried 137
hypopodes ofEuglycyphagus, on the pronotum, metasternum, elytra and
abdomen. Euglycyphagus is fungivorous to some extent and, like the his-
tiostomatids, was most abundant in the basal debris. Histiostomatid and
glycyphagoid mites have not previously been found on trogid beetles,
although Fain and Philips ( 1978b) have described a new species of win-
terschmidtiid mite from Australian trogid beetles.

Sapracarus tuberculatus Fain and Philips, known only from this nest,
may be a strict nidicole or general tree-hole dweller. Its entomophilic
hypopus indicates a phoretic relationship with some insect. This mite is
presumably detritivore, but no gut contents were visible in the speci-
mens examined.

Echimyopus is a mite genus known as deutonymphs from hair follicles
and skin galls of Central American rodents and marsupials (Fain, 1969;
Fain etal., 1973; Fain and Lukoschus, 1976). One previous record of the
genus exists for North America, from squirrel hosts (Whitaker et al.
1975). Adults and nymphs of this genus had not previously been found
(Fain and Philips, 1981).

Orycteroxenus hypopodes occur on mammal hair, and the occurrence
of one hypopus of O. soricis (Ouds.) can be correlated with our finding of
prey remains of one of its hosts, Microtuspennsylvanicus (Fain, 1969; Fain
and Whitaker, 1973). Neoxenoryctes hypopodes also are pilicolous, and
the nymphs and adults are at least partly fungivorous.

The chigger Miyatrombicula cynos Ewing is known from raccoons
and squirrels (Ewing, 1937; Whitaker^ al., 1975). All stages of this mite
were found in the nest, and over half of the larvae were engorged. Since
many chiggers show little host specificity, it is possible tht the screech
owl could be an acceptable host for this species, but more likely the hole
had been used by squirrels previously, and the owls had only recently
taken possession again for nesting.

Tarsocheylus paradoxus Berl. is known from tree-holes and rotting
bark (Atyeo and Baker, 1964). Pyemotids, scutacarids, tarsonemids, and
tydeids are all soil and litter groups, which pierce and suck fluids from

174 ENTOMOLOGICAL NEWS

fungi and/or nematodes (Moore et al., 1988). Proctotydaeus is an insect
associate (Andre, 1980) and may have reached the nest on moths, since
Treat ( 1 96 1 ) found one species phoretic on noctuid moths. Cheyletids are
common nest predators, and Woodroffe (1953) observed that the acarid
mite Tyrophagus is preferred prey for Cheyletus eruditus (Schr.); perhaps
in this nest it was mainly preying on Acotyledon, the most abundant
acarid mite present.

The mesostigmatic mites found included gamasine parasites of birds
and mammals, gamasine predators, and uropodine fungivores. Species
of Laelaps, Haemogamasus, Hyperlaelaps, and Androlaelaps fahrenholzi
(Bed.) are small mammal parasites with many hosts (Whitaker and
Wilson, 19"y '4). Androlaelaps casalis (Berl.) has been described as a mam-
mal and bird ectoparasite common in bird nests (Wilson and Bull, 1977.,
Rosen et al. 1985), but McKinley (1963) concluded that this species did
not pierce mammal or avian skin, and actually fed on other mites, such
as acaridids, and their eggs.

Hypoaspis, Blattisocius, and Proctolaelaps are common nest predators.
The size difference in the three Dendrolaelaps species suggests possible
differences in prey size classes. Many ameroseiids feed on fungi or
pollen, but can also be predators (Krantz, 1978). They occur in litter as
well as mammal nests. Among the uropodines, Metagynella parvula
Camin is known only from tree-holes (Camin, 1953). Its phoretic relation-
ships, if any, are unknown. One deutonymph of Trichouropoda martini
Hirschmann was phoretic on the histerid beetle Dendrophilus xavieri
Marseul. Trichouropoda martini is known from a red squirrel (Tamias-
ciurus) nest (W. Hirschmann, pers. comm.). Uroseius deutonymphs have
been found in passerine nests phoretic on trogid beetles (Sixl, 1971).

The pseudoscorpion Acuminochernes crassopalpus (Hoff) is a pred-
ator that has been previously recorded from treeholes (Park and Auer-
back, 1954) and mammal nests (Muchmore, pers. comm.). Chernetid
pseudoscorpions posses several adaptations for colonizing nests and
treeholes, including phoresy and the ability to store sperm for prolonged
periods (Jones, 1975).

Most of the fly larvae are known scavengers on animal remains, but
scenopinid larvae prey mainly on tineid moth larvae. The cecidomyid
larvae were probably saprovores associated with the decaying nest
plant matter.

Beetles associated with treeholes rather than birds' nests included the
curculionid adult and the melandryid, tenebrionid and staphylinid lar-
vae (Borroretal., 1981). Xylodromus is a new staphylinid record for New
York (Moore and Legner, 1975). The histerid beetles were the largest
predators in the nest.

Only a few fleas were found, and both species are mammal parasites.

Vol. 101, No. 3. May & June 1990 175

Orchopeas howardi (Baker) is most commonly found on tree squirrels
and O. leucopus (Baker) prefers Peromyscus (Main, 1970). Ixodes marxi
Banks, the single tick found, is also a tree squirrel parasite (Bequaert,
1945).

The single psocopteran appears to be an accident. It may have been
windborne or reached the nest on a bird or mammal, as phoresy occas-
ionally occurs in psocopterans (Mockford, 1967). The only wasp found.
Synergus, was extracted from a gall on one of the nest leaves.

The ectoparasites found included the squirrel tick, the squirrel flea, a
squirrel chigger, three parasitic mesostigmatic mite species known from
squirrels, and an astigmatic mite genus known from squirrels. Also, the
nest contained many mammal nest associates such as Fusacarus and
Neoxenoryctes. Oakwood Cemetry abounds in gray squirrels (Sciurus car-
olinensis Gmelin), and it seems inevitable that this tree-hole would be
occasionally visited by squirrels when not used by the owls. In 1977, the
owls again nested in this hole, as they had for several previous years, but
in 1978 squirrels took over the hole and the owls did not nest there.

Squirrel use of the hole explains the many squirrel parasites found.
We believe that the hosts o{ Echimyopus orphanus Fain and Philips and
Neoxenoryctes is the gray squirrel, and that these other genera like
Fusacarus will also be found in gray squirrel nests.

This nest community was characterized by very high species richness
and very lowequitability. The variety of food sources in the tree-hole nest
provide a habitat for many species which colonize the hole deliberately
or accidentally, and the protected microenvironment seems to provide
nearly optimal conditions for some species.

American Kestrel Nest Fauna

The kestrel nest invertebrate community was very different from the
screech owl nest community. Of 93 species in the kestrel nest, only 12
were also present in the screech owl nest. These species - 9 mites, a his-
terid beetle, a sphaerocerid fly, and a psocopteran - included no avian
parasites and were small components of both nests, comprising only 8%
of the individuals in the screech owl nest, and 4% of those in the kestrel
nest. Four of the mites are parasitic or phoretic on rodents. Three addi-
tional species may be common to both nests. Lack of adults of the
scenopinid fly, the tineid moth in the kestrel nest, and the uroseiid mite
in the screech owl nest, prevented complete identification.

Diversity in the kestrel nest was lower than in the screech owl nest.
Although species richness was higher than that of the screech owl nest,
equitability was lower, as was arthropod density. In this nest, a new
species ofLardoglyphus, a genus known from dried fish, butchers' offal.

176 ENTOMOLOGICAL NEWS

and hides (Hughes, 1976) was highly numerically dominant. This species
was fungivorous to some extent, and the hypopodes were phoretic on
Dermestes pulcher LeConte (Philips and Norton, 1978). It seems to have
some degree of host specificity. A nest box in a tree 18m from this kestrel
nest was examined and preliminary inspection has revealed neither Lar-
doglyphus falconidus Philips and Norton nor its dermestid host species.
Another genus of dermestid was present, as were the species ofLepido-
glyphus and Cheyletus which occurred in this kestrel nest.

Other genera of acarid mites in this nest with entomophilic hypo-
podes were Histiogaster, Michaelopus, Sancassania, and Schwiebea.
Michaelopus corticalis (Michael) has been found under dead tree bark
and in nests of several avian orders (Fain, 1982), and is probably sap-
rophagous like Sancassania and Schwiebea. Schwiebea terrana Jacot was
originally collected from pine litter and inhabits dead wood (Wood-
ring, 1966a).

Histiostomatid mite hypopodes were found phoretic on Trox seaber
(L.) in this nest, as they were on the other species of trogid beetle in the
screech owl nest. Thirteen hypopodes were found under the wings of the
trogid, in crevices at the border of the thoracic and abdominal regions of
the body. Twelve hypopodes were Histiostoma species number three, and
one was Hexanoetus conoidalis Fain and Philips. Hexanoetus conoidalis
was present in adult and immature stages in the screech owl nest. Histios-
toma species number 3 is identical to the Histiostoma species B found by
Philips etal. (1983) under the elytra of four specimens of Troxaequalis Say
in a saw-whet owl (Aegolius acadicus (Gmelin)) nest in Connecticut.

Two species of feather mites were found in the nest. The specimens of
Dubininia in the pellet sample may have been regurgitated with a pellet
or may have dropped off from a kestrel in the nest, as this genus is a
parasite of the Falconiformes as well as other birds. Analges probably
was derived from prey.

Lepidoglyphusfustifer(Ouds.) is a European stored products species.
It has not previously been recorded from North America (Hughes, 1976)
and the hypopus stage was not previously known from this species. We
have observed fungal spores in the gut of many of our specimens.

As with the screech owl nest, a few Orycteroxenus hypopodes were
found, as well as evidence of predation on Microtus. Glycyphagus
hypudaei (Koch) hypopodes are phoretic on Microtus and many other
small mammals. Myocoptesjaponensis Radford is a parasite whose type
host is Microtus pennsylvanicus and type locality is Ithaca, N.Y. (Fain and
Hyland, 1 970). Dermacarus sciurinus ( Koch), another mammal associate,
is known from a Peromyscus nest (Fain and Whitaker, 1973).

Tytodectes cerchneis Fain was previously known only from one badly
damaged specimen found on Falco tinnunculus L. in Rwanda, Africa

Vol. 101, No. 3, May & June 1990 177

(Fain 1967). The hypoderid mites are a poorly known group, and the life
cycle of very few species is completely known. The hypopus is a sub-
cutaneous parasite of birds, and the other immature stages are not active.
The adults are very short-lived and nonfeeding nidicoles (Fain and
Bafort, 1967).

The finding of Tytodectes represents a new U.S. record. Both Falco
sparverius and F. tinnunculus also have a nasal mite species in common,
and it would be interesting to survey falcon nasal, subcutaneous, and
other mites and compare that data with concepts in falcon taxonomic
relationships.

Nanacarus is a new New York record. This genus contains a number
of fungivorous species which inhabit polypore fungi (O'Connor, 1984).

Among the prostigmatic mites present were two mammal parasites -a
nymphal myobiid mite and a Demodex, as well as tarsonemid and tydeid
soil and litter species. There was no mammal carrion in the nest, so we
believe the parasites either came off prey in the nest before the prey
was eaten, or survived the bird's digestive tract and came out in regurgitated
pellet or fecal material.

Cheyletus trouessarti Oudemans was the most abundant predatory
mite in the nest. Cheyletids are often associated with infestations of
acarid mites (Baker, 1949) and we believe this species was probably feed-
ing mainly on the abundant Lardoglyphus in this nest. Anystids are very
mobile predatory mites which often feed on phytophagous insects and
mites. The one larvae found may have wandered into the nest box from
the tree the box was on, as these mites are long-legged rapid movers
(Krantz, 1978).

As with the screech owl nest, the mesostigmatic mites included gama-
sine mammal parasites, gamasine predators, and uropodine fungivores.
but there were no gamasine avian parasites. Poecilochirus necrophori
Vitzth. is known to be phoretic on the silphid beetle Nicrophorus
(Chmielewski, 1977) and the presence of four on Nicrophorus pustulatus
Hers, explains how this mite reached the nest. This mite probably preys
on nest fly larvae. Macrocheles muscaedomesticae, another immature dip-
teran predator (Peck and Anderson, 1969), is known to be phoretic on
muscid flies (Evans and Browning, 1956; Chmielewski, 1977). Copriphis
is a predatory gamasine which is phoretic on scarabaeid dung beetles.
Two females were found under the wings otTroxscaber near the thorax/
abdomen border. This species is identical to the species of "Eviphis"
found by Philips el al. ( 1983) under the elytra of Trox aequalis in a saw-
whet owl nest in Connecticut. Copriphis has been considered by some
taxonomists to be a synonym ofEviphis, but we agree with those regard-
ing it as a distinct genus. Ameroseiusapodius Karg was discovered by Karg
( 1 97 1 ) in compost in Germany, and has not previously been found in the

178 ENTOMOLOGICAL NEWS

U.S.A. Trichouropoda falconis was recently described as a new species
from this nest by Hirschmann and Wisniewski (1988). Trichouropoda
species number one was found as a phoretic deutonymph attached by
anal stalk to tibia IV of an adult histerid beetle, Carcinops pumilio
Erichson.

Very feworibatid mites were present in this nest, which was dominated
by animal remains fauna. Other humus fauna species were equally
scarce - one collembolan, one enchytraeid, two earthworms, and a few
Psocoptera. To our knowledge, earthworms have only been previously
recorded from nests of one bird - the rook (Corvusfrugilegus L.) in Britain
(Coombs, 1960). Earthworm presence in a kestrel nest may be due to prey
escape, since kestrels prey on earthworms (Balgooyen, 1976). Clubionid
spiders hunt both on the ground and in foliage (Kaston, 1972), and prob-
ably entered the nest while foraging on the tree.

Histerids again were the largest predators in the nest. While the food
of many species of staphylinids is not known, Koskel and Hanski (1977)
classify all aleocharines and staphylinines (like Philonthus) as
carnivores. Nicrophorus may prey on maggots, as well as eating carrion
(Steele, 1927). Lathridiid and tenebrionid fungivores are very common
in birds' nests and Tenebrio molitor L. is a stored products pest (Woodroffe
and Southgate, 1951).

Calosoma frigidum Kirby is a new prey record for the American
kestrel (Philips, 1977). This carabid beetle was known to be preyed upon
by only one bird - the ruffed grouse (Bonasa umbellus (L.)) (Larochelle,
1975), but this demonstrates the paucity of knowledge on avian insect
predation.

Allen (1973) has noted that this carabid preys upon several important
insect pests, and its habit of tree foraging may make this species more
susceptible to kestrel predation than cryptozoic ground carabids, par-
ticularly when, as Allen observed, large numbers of this carabid beetle
occur during major infestations of forest insect pests.

The trogid and dermestid beetles eat hair and feathers in animal
remains like carrion and raptor pellets. Trox scaber (L.) is known from
mammal nests and nests of several other birds, including the screech owl
(Vaurie, 1955). Unidentified species of Dermestes were recorded from
kestrel nests by Balgooyen (1976). Nicrophorus feeds on fresher carrion
than Dermestes.

Scavenging dipteran larvae occurred as in the screech owl nest, but in
much greater numbers and in greater variety, with muscid and scatopsid
flies present. Two families of avian parasitic flies inhabited this nest. The
biting midges (ceratopogonids) suck blood, but the food habits of the
nidicolous milichiid Camus hemapterus Nit. have been a subject of
debate. Bequaert (1942) has quoted the observations of earlier workers

Vol. 101, No. 3, May & June 1990 179

who discovered that it fed on blood and that it fed on skin and feather
secretions. Borror et al. ( 1981) consider it to be blood-sucking. Lloyd and
Philip (1966) agreed with Bequaert that the mouthparts are not adapted
for piercing host skin.

One parasitoid cynipid wasp inhabited this nest, but the hosts of
many species of Pseu deucoila are not known (Muesebeck et al., 1 95 1 ). The
mymarid wasp is a parasite of insect eggs (Borror et al. 1981). Many
braconid wasps are parasites of lepidopteran larvae (BorroTetal. 1981).
Lasius ants nest in rotting logs and stones and cultivate aphids (Arnett,
1985). The three nest anoplurans can be attributed to the birds' mam-
malian prey. The two flea larvae could not be specifically identified.

DISCUSSION

These raptor nest data present a considerably different picture of the
nest community than previous studies. Although Nordberg ( 1936) found
oribatid mites of many species in his European raptor nests, very few
species occurred in our nests. Nordberg found mainly feather mites
among the astigmatic mites in his nests, but our nests contained a wide
variety of astigmatic mites. The prostigmatic and mesostigmatic mite
components of raptor nests are also much more diverse than were prev-
iously realized. In particular, no mammalian-associated mites had been
reported from raptor nests. Our expectations that they would be found
still did not encompass the actual extent of the mammal nest and para-
site fauna in raptor nests.

The mite family Pyroglyphidae is very common in birds' nests
(Woodroffe, 1953; Krantz, 1978), but has never been previously found in
raptor nests, and only three specimens were found in our nest samples.
Its scarcity in the kestrel nest is even more surprising considering its
abundance in a tree swallow (Iridoprocne bicolor (Vieillot)) we examined
which was in a nestbox only 200 m away. More samples are needed to
confirm this apparent preference for nonraptor nests - perhaps the rap-
tor nest moisture and carrion create an unattractive environment. Wood-
roffe (1953) noted that these mites are tolerant of low humidities and
occur in very dry nests. Some nest pyroglyphids also occur in house dust
and cause house dust allergy (Krantz, 1978).

Referring to mites in bird nestbox debris, Herman (1936) stated that
"an estimate of billions in each nest seems conservative". He correctly
judged the importance of the mites, if not their actual density. Neverthe-
less, the densities of arthropods in the screech owl and kestrel nests are
high. Park et al. (1950) studied the tree-hole fauna of elm, sugar maple,
and beech trees, and arthropod densities ranged from 4.4-5.5/g. Ryder
and Freitag (1974) examined ring-billed gull (Lams delawarensis Ord)

180 ENTOMOLOGICAL NEWS

nests of weights similar to the screech owl and kestrel nests, and densities
averaged 1.5-1.7 arthropods/g.

The oribatid mite density in the screech owl nest appears to be
unmatched in any other reported nest. Gembestky and Andrechikova
(1969) examined 32 nests of 7 passeriform species and collected only 98
oribatid specimens. Bukva etal. (1976) found 979 oribatids in 278 small
mammal nests, and Kramarova and Mrciak( 1971) collected 13,364 from
303 small mammal nests.

Kramarova and Mrciak studied the invertebrate groups in small
mammal nests as we did with the raptor nest groups. Some additional
numbers from their 303 nests provide a useful comparison: 20,556 astig-
matic mites; 110,575 mesostigmatic mites; 679 prostigmatic mites; 71
pseudoscorpions; 22,2 1 3 Collembola. Vysotskaya and Nosek ( 1 974) studied
43,796 Collembola from 464 small mammal nests.

The dominance of gamasine mites, especially parasites, in small
mammal nests has also been shown by Drummond (1957) and Allred
and Roscoe (1957). Judging from our data, astigmatic or oribatid mites
can be dominant in raptor nests, and although a variety of mesostigmatic
mites occur, they are not present in tremendous numbers.

Park and Auerbach (1954) found that collembolans made up 27% of
the tree-hole fauna they studied. Considering their abundance in small
mammal nests and treeholes, the scarcity of collembolans in the raptor
nests examined is surprising. Further study is needed to determine the
frequency of Collembola in many raptor nests.

Woodroffe and Sou thgate (1951) studied passerine nests and observed
a succession of invertebrates. Avian ectoparasites dominated during ini-
tial nest construction and occupation. After birds left the nest,
scavenging invertebrates were dominant as feather debris and excreta
decomposed. The final stage of decomposition of the nest material was
dominated by humus fauna. If the nest was used as a winter roost and
reused the next year, the nest acted as a refugium and the scavenging
fauna persisted. Open, exposed nests decomposed faster and the scaveng-
ing stage was reduced or absent. Differences in the fauna of nests of dif-
ferent bird species were correlated with differences in the composition of
the nests.

This pattern is not consistent for all birds' nests. Freitag and Ryder
(1973) found almost no ectoparasites in their ring-billed gull nests. Sap-
rophagous mite populations peaked after gull egg-laying, while pred-
atory mite populations peaked at or after egg-hatching (Freitag et al,
1974).

Trophic category estimates of the raptor nest fauna are given in Table
4. There is no evidence that the raptor nests followed Woodroffe's

Vol. 101, No. 3. May & June 1990 181

scheme, as very fewavian ectoparasites were found. However, the scaveng-
ing animal remains fauna was dominant in our samples taken im-
mediately after falconiform nesting. The effects of screech owl nesting
upon the nest humus fauna were not observed because of our distur-
bance of the site. It is possible that this fauna could have remained domi-
nant throughout the entire nesting period, but an increase in the animal
remains fauna would still be expected as that food source became
more abundant.

Hagvar (1975) described coleopteran succession in raptor nests.
Nests used every year grow larger, older material decomposes, and the
number of niches increases. Old nests in use have the largest species
richness, and large old nests can remain humid in the center even
during droughts.

Succession in raptor nests is complicated by the many variables in
nest location and use. Nests may be used in other seasons and years by
other roosting species, and raptors may share their nests with a variety of
other vertebrates (Wilson, 1925; Sumner, 1933; Zarn, 1974).

Detailed investigations of raptor nest fauna are needed to elucidate
the intricate interrelationships in this microcommunity. Many raptors
are marginal or endangered species, and we need to know what, if any,
invertebrates may be a source of mortality and how frequently this
occurs. When nest trophic interactions are well known, biological con-
trol measures against undesirable invertebrates may be possible.

Titles should be carefully composed to reflect the true contents of the article, and be kept as
brief as possible. Classification as to order and family should be included in the title, except
where not pertinent. Following the title there should be a short informative abstract (not a
descriptive abstract) of not over 1 50 words. The abstract is the key to how an article is cited in
abstracting journals and should be carefully written. The author's complete mailing address,
including zip code number, should be given as a footnote to the article. All papers describing
new taxa should include enough information to make them useful to the nonspecialist.
Generally this requires a key and a short review or discussion of the group, plus references to
existing revisions or monographs. Authors must include the name(s) of recognized institutions )
where their voucher specimens have been deposited. Illustrations nearly always are needed.
All measurements shall be given using the metric system or, if in the standard system,
comparable equivalent metric values shall be included. Authors can be very helpful by
indicating, in pencil in the margin of the manuscript, approximate desired locations within the
text of accompanying figures, tables and other illustrations.

Illustrations: For maximum size and definition, full page figures, including legends, should
be submitted as nearly as possible in a proportion of 4/6. Maximum size of printed illustration,
including all legends, is 4Vi x 6Vi inches. Authors will be charged for all text figures and half-
tones at the rate of $7.50 each, regardless of size.

Study notices, want items and for sale notices are published in The Entomologist's Market
Place.

Page charges: A charge of $15. 00 is made for each published page of an article, plus costs of
all illustrations. If any charges are not paid within 120 days of date of billing, authors will be
charged an additional $5.00 per page. Papers may be published ahead of their regularly
scheduled time at a cost of $35.00 per page.

Reprints: (without covers) may be ordered when corrected page proofs are returned to the
editor. Schedule of reprint costs will appear on order form.

BIOGEOGRAPHIC AFFINITIES OF THE

EPHEMEROPTERA OF THE BLACK HILLS,

SOUTH DAKOTA 1 ' 2

W. P. McCafferty 3

ABSTRACT: Records of mayfly species in South Dakota are few in number. Most records
are from the Black Hills region of southwestern South Dakota. Twelve new species records
(genera Caenis. Callibaetis, Dactylobaetis, Epeorus, Nixe. Paraleptophlebia, Siphlonurus.
Tricorythodes) are also based on collections from the Black Hills. The diversity of the mayfly
fauna in the Black Hills is relatively low, with only 19 species in seven families known. The
species mix consists of some widespread North American species, but also western con-
tinental species and eastern continental species whose respective easternmost and
westernmost range limits meet in the Black Hills. The somewhat insular nature of this
small montane region may explain low numbers of species, and its proximity to the main
body of Rocky Mountains may explain the presence of its western component. Eastern
species represented are primarily northeastern North American species with disjunct, pro-
bably relict populations now isolated in the lower Appalachian Mountains, the Ozark-
Ouachita Mountains, and the Black Hills.

Very few published records of Ephemeroptera species in South
Dakota have been established. Species previously reported from the
Black Hills region of southwest South Dakota are included in Table 1.
The Black Hills region referred to herein includes Custer. Fall River,
Lawrence, and Pennington Counties (Fig. 1). The previous records were
given by Morihara and McCafferty (1979) for the Baetidae, and by Allen
and Edmunds (1965) for Ephemerella inermis. Examination of addi-
tional materials of all of these previously reported species has substan-
tiated their presence.

Even fewer records have been established for areas of South Dakota
outside of the Black Hills region. In recent revisions, Bednarik and
McCafferty (1979) recorded Stenonema mediopunctatum arwini from the
Yellowbank River in extreme northeastern South Dakota, and Kon-
dratieff and Voshell (1984) recorded Isonychia rufa from Sioux Falls in
the southeast corner of the state. There are new state records of mayflies
based on species I have examined from eastern South Dakota, but these
will be published as part of revisionary studies now in progress.

Two primary factors have prompted the present report. First, it has
become increasingly important to survey the North American fauna
with respect to documenting biodiversity. Second, the Black Hills region
is important biogeographically since, as will be discussed below, it con-

tains one of the most unusual mixes of mayfly faunal elements found in
North America.

All species records for the Black Hills region reported by Morihara
and McCafferty (1979) and all but one reported here for the first time
(Table 1) have been based on collections made by me and by A. V. Pro-
vonsha and B. L. Heath in June, 1975 (Sites 2-17 in Table 2 and Fig. 1).
Site 1 (Table 2 and Fig. 1) was collected in November, 1977, by an
unknown collector. All larvae upon which data in Table 1 are based are
deposited in the Purdue Entomological Research Collection, West
Lafayette, Indiana.

In addition to a list of species taken in the Black Hills region, Table 1
indicates numbered collection sites where each species was found. These
sites are plotted on a map of the region (Fig. 1 ) and are detailed in Table 2.
Also included in Table 1 is an indication of the general North American
distribution of each of the Black Hills species.

A rather striking pattern of biogeographic affinity is found for a large
proportion of Black Hills species. Black Hills records represent the
extreme range margin for 13 of the 19 species listed. Ten of the species are
western continental or eastern continental species whose respective
easternmost or westernmost fringes of their ranges apparently include
the Black Hills. For the three other species, the Black Hills distribution is
apparently along their northern or northeastern range margin.

Among the Baetidae, the species listed as widespread are generally
distributed with a broad east-west transcontinental pattern. In the case
of Callibaetis fluctuans and Diphetor hageni, these transcontinental pat-
terns are somewhat restricted north and south, with either a mid-latitude
or more northern pattern, respectively. Fallceon quilleri is widespread but
only as far east as Illinois (Burks 1953, as B. cleptis) and Louisiana (Lager
1985) and is mainly southwestern and south-central in distribution. Fall-
ceon quilleri may actually represent a complex of more than one species,
but requires further systematic study (Waltz and McCafferty 1987a). In
the case of Callibaetis pictus, although the range is signified as western in
Table 1 , it also extends into some south-central states as far east as Texas.
Those species listed as eastern generally have midwestern as well as
more eastern distributions.

Baetis brunneicolor, B.flavisriga, and B. intercalaris are eastern species
whose westernmost distribution limits are represented by disjunct pop-
ulations in the Black Hills. Acentrella insignificans and Dactylobaetis
cepheus are western species whose easternmost limits appear to be in the
Black Hills. With respect to D. cepheus, this may have been the species
that Lehmkuhl (1976) reported as Dactylobaetis sp. from Saskatchewan.
Whereas biogeographic affinities of Dactylobaetis are Neotropical

Vol. 101, No. 4, September & October 1990 195

(Traver and Edmunds 1968), those ofAcentrella are Holarctic (Waltz and
McCafferty 1987b). The Black Hills are along the northern fringe of the
known ranges of Callibaetis fluctuans and C. pictus. Fallceon quilleri has
been reported from Saskatchewan (Lehmkuhl 1976), but the Black Hills
distribution may be disjunct and along its northeastern range margin.
Eventually, the Callibaetis species probably will be found in Saskat-
chewan.

The Heptageniidae is the only other family with more than one
species listed for the region. Epeorus grandis and Nixe criddlei are western
species whose eastern limits are apparently the Black Hills. Records of
the latter species from Fort Collins, Colorado (Traver 1935) are nearly as
far east.

Of the remaining species, Caenis arnica is widespread and ubiquitous
(Provonsha 1990), and Tricorythodes minutus is also widespread except
for its absence from the Southeast (Berner 1977). Siphlonurus colum-
bianus and Ephemerella inermis are western species whose eastern limits
are apparently the Black Hills, although E. inermis is reported from
Saskatchewan (Lehmkuhl 1976), and I have seen S. columbianus from
north-central Colorado. Hilsenhoff (1987) reported that either E. inermis
or a sibling of it occurs in Wisconsin. I would not expect this species in
Wisconsin, given its absence in places such as Manitoba and Minnesota
(Flannagan and Flannagan 1982, Lager et al. 1982), but I have not
studied the Wisconsin material. Paraleptophlebia mollis is a mainly
northeastern species whose previous westernmost known distribution
included Manitoba and Minnestoa (Flannagan and Flannagan 1982.
Lager et al. 1982).

In conclusion, there are at least three aspects of the Black Hills
mayfly fauna that are noteworthy. First, the diversity of species is rela-
tively small. This perhaps could be explained by the fact that the region is
a somewhat insular montane area. Its isolation from other montane
areas may be an obstacle to dispersal for many mayfly species.

Second, the Black Hills represent the easternmost limits for certain
western species. The montane nature of the region would perhaps explain
the presence of such species that have populations located proximally in
the main body of the Rocky Mountains and that are relatively good
dispersers.

Third, and what might appear to be the most difficult to explain, four
eastern species have westernmost limits in the Black Hills. Baetis bnm-
neicolor and B. flavistriga are, however, mainly northeastern and upper
midwestern in distribution (Morihara and McCafferty 1979) as is the
Paraleptophlebia mollis (Traver 1935). Although mainly lowland species
in their primary range, their range extensions outside of this area are dis-

196 ENTOMOLOGICAL NEWS

junct in montane areas: Unzicker and Carlson (1982) reported B. brun-
neicolor from North Carolina; Peters and Warren (1966) reported B.
flavistriga (as B. levitans) from the Ozark Mountains of Arkansas, and
Berner ( 1977) reported this same species from Tennessee and North Car-
olina; and Traver (1937) confirmed P. mollis from North Carolina, and
McCafferry and Provonsha (1978) found it in the Ouachita Mountains
of Arkansas. This type of pattern in North America probably indicates a
relict distribution, where certain cold-water species have become restric-
ted to northeastern regions and isolated in certain disjunct montane
areas outside the Northeast as a result of glacial events during the
Pleistocene.

Although the distribution oi Baetis intercalaris is similar to the three
other eastern, Black Hills species, this species is found in more divese
lowland and upland locations in the East, including areas such as
Florida and Alabama (Morihara and McCafferry 1979). The western dis-
junction in this instance is therefore more difficult to interpret. The
species does occur in the lower Appalachians and the Ozarks (Morihara
and McCafferty 1979), but these are not disjunctions. Perhaps the species
has been a better post-glacial disperser, and since it appears more ubi-
quitous, perhaps will be found in lowland areas adjacent to, and east of,
the Black Hills. This apparent anomaly, however, may not actually exist
if it is an artifact of our inexact taxonomy. Baetis flavistriga and B. inter-
calaris are closely related and morphologically cryptic as larvae, being
separable only by color pattern (Morihara and McCafferty 1979). There-
fore, it is possible that what we have determined to be B. intercalaris in the
Black Hills is a color variation of B. flavistriga that resembles B. inter-
calaris in other areas. Baetis ochris is another closely related and similar
species that may be involved.

ANTHOPOTAMUS, A NEW GENUS FOR

NORTH AMERICAN SPECIES

PREVIOUSLY KNOWN AS POTAMANTHUS

(EPHEMEROPTERA: POTAMANTHIDAE) 1 ' 2

W.P. McCafferty, YJ. Bae 3

ABSTRACT: Comparative studies of all life stages of potamanthid mayflies worldwide
have indicated that North American species historically placed in the genus Potamanthus
are generically distinct from all Palearctic Potamanthus, including the type of the genus, the
European species P. luteus (Linn.). Close phylogenetic relationships of the Nearctic species
of Potamanthidae are with East Asian genera, but not Palearctic Potamanthus. The new
genus Anthopotamus [type species = A. verticis (Say), new combination] is therefore estab-
lished for the Nearctic fauna of Potamanthidae. A brief synopsis of the new genus is
provided, and a biogeographic origin of the new genus is suggested.

The genus Potamanthus Pictet in North America was most recently
reviewed by McCafferty (1975). Although the classification (McCafferty
and Edmunds 1979) and the phylogeny (McCafferty 1979) of Potamanthidae
within the higher groups of Ephemeroptera have been recently pre-
sented, the systematics within the family have not been studied
comprehensively. Members of this clearly monophyletic family, com-
monly known as hacklegills (McCafferty 1981), are distributed in the
Holarctic and Oriental Realms, with several genera occurring in East
Asia, but only Potamanthus occurring in North America. We are
currently conducting a revisionary study of both species and genera of
the Potamanthidae. This has been possible only by bringing together
material from throughout the world for comparative study.

Potamanthus, as it has been constituted, is known from North
American and Eurasia. The type of the genus is P. luteus (Linn.), a
common European species that was first described in Ephemera in 1767.
We have studied adults and larvae of Nearctic and Palearctic Potamanthus
in detail, including/ 1 , luteus. Our comprehensive comparisons with other
potamanthids from the entire range of the family clearly show that
species in North American are distinct from P. luteus. The degree of
demarcation is equivalent to, or more than, that found in well-established,
valid genera in the family. Asian species of Potamanthus do, however,
agree with the type concept of the genus. Thus, the North American
species constitute a separate and distinct grouping that require classification

in a new genus. The most compelling reason for removing the Nearctic
species from Potamanthus is our finding that they are phylogenetically
removed from Palearctic Potamanthus and are instead more closely
related to other East Asian genera.

Because ecological and behavioral data dealing with various North
American potamanthid species are about to be made available for publi-
cation (Bae and McCafferty unpublished, D.C. Tarter, pers. comm.) and
publication of the family revision will not be forthcoming for at least
another two years, it is appropriate to report this systematic finding and
make a new generic name available at this time. Therefore, a new genus
is established herein and a brief synopsis and discussion of the taxon is
given.

Anthopotamus, new genus

Type Species. Potamanthus verticis(Say), 1839:42, orginally as Baetis.
Species Included. Anthopotamus diaphanus (Needham), A. distinctus (Traver), A.
inequalis (Needham), A. mvops (Walsh), A. neglectus (Traver), A. rufous (Argo), A. verticis
(Say), and A. walkeri (Ide),' all NEW COMBINATIONS.
Distribution. Eastern half of North America.

Etymology. The name Anthopotamus is a masculine name taken from the Greekanthos
(flower) and potamos (river). The allusion to a "river flower" is analogous to the other
generic names in Potamathidae, which also denote river flowers.

Diagnosis. Larvae of Anthopotamus have long, well-developed
mandibular tusks, highly developed mouthpart setation, and well-
developed rows of long setae on the foretibiae (see Fig. 3 in McCafferty
1975 and Fig. 7.42 in McCafferty 1981). Potamanthus larvae, on the other
hand, have rudimentary tusks and poorly developed mouthpart and
foretibiae setation in comparison (e.g. see Fig. Ib in Macan 1979). Adults
of Anthopotamus can be distinguished from those of Potamanthus by the
generally smaller compound eyes of the males (ratio of eye diameter to
dorsal distance between compound eyes is less than 0.2), as well as a
much longer prothorax, and generally lighter coloration.

Relationships. Our cladistic analysis, details of which will be pub-
lished as part of the revisionary monograph, indicate that the Old World
genus Potamanthus (sensu novum) represents an ancestral, early branching
lineage within the Potamanthidae. Its sister lineage contains all other
Potamanthidae, a grouping consisting of East Asian genera as well as
Anthopotamus. Within this later Ymeage, Anthopotamus is intermediate in
position between the more ancestral Potamanthodes and the more derived
Rhoenanthus. Anthopotamus is not closely related phylogenetically to
Potamanthus, wherein its species were previously included.

Most probably, an Anthopotamus-Mke ancestral lineage spread to
North America via Beringia in pre-Pleistocene times. Vicariance of this

202 ENTOMOLOGICAL NEWS

Holarctic, Arcto-Tertiary distribution would have probably paralleled
the phyletic split into a Nearctic "Anthopotamus" lineage and the
Palearctic "Rhoenanthus" lineage. If more derived elements of
Potamanthidae were very widespread in the Holarctic during the
Tertiary, then perhaps glacial events during the Pleistocene would ex-
plain the present absence of this element in Europe and western North
America. Such Arcto-Tertiary and subsequent patterns are well documented
in plant and animal genera, e.g. see review of Pielou (1979).

CYTOLOGY OF LEPTOGLOSSUS ZONATUS
(HEMIPTERA: COREIDAE) 1

Richard J. Packauskas''

ABSTRACT: The diploid chromosome complement of Leptoglossus zonatus (Dallas)
males is shown to consist of 21 chromosomes: 1 8 autosomes, 2 microchromosomes, and an
X chromosome. There are two large homologous pairs (4-5 microns in length). The
remaining autosomes and the X chromosome range from 2-3 microns in length, and the
microchromosomes (which are round) are 1 micron in diameter. Major meiotic events of
the species are briefly characterized.

The Coreidae is a very large and diverse family, and many species
within it have been examined cytologically. Most coreids investigated
have a pair of microchromosomes and an XO sex mechanism. The
chromosomes are holokinetic (diffuse centromeric), as are those of all
Hemiptera (Thomas 1987). Coreid chromosome numbers range from 2n
= 13 to 2n = 28; the most common number is 2n = 21 (Ueshima 1979).
The genus Leptoglossus Gue'rin belongs in the coreine tribe Anisoscelidini.
some of whose members have been investigated cytologically (Piza 1 945,
1956; Wilson 1907, 1909).

Here I examine the cytology of Leptoglossus zonatus (Dallas) and
relate this to previous studies. The chromosome number of this species
has never been published, nor have meiotic events in this genus been
charactetized.

MATERIALS AND METHODS

The figures and observations were based upon preparations made
from 3 male fifth instars collected in Panama and alcohol preserved
(70% ethyl) in August of 1987. A modification (Jane O'Donnell, unpubl.)
of a technique (Ueshima 1963) for preparation of alcohol-preserved
specimens was used with good results even after a year of storage: 1)
testes were dissected out in alcohol and placed for 1 2 hours in the fixative
isopropyl carnoy (3 parts pure isopropyl alcohol, 1 part glacial acetic
acid); 2) they were transferred to glacial acetic acid and heated gently
over an alcohol lamp for 5-10 minutes; 3) the preparation was allowed to
cool to room temperature, and then placed in a drop of aceto-carmine; 4)

a cover slip was applied and the material squashed with a few hard taps
of a pencil eraser. All preparations were subsequently mounted in
Diaphane to make them permanent (Sharma and Sharma 1972). Drawings
were made with the aid of an ocular grid, and measurements with an
ocular micrometer.

OBSERVATIONS

Observations were recorded as drawings; only brief explanatory
comments are offered.

Spermatogonial phases are easily seen in L. zonatus, but these are not
always easily analyzed. The spermatogonial chromosomes do not spread
well in a squash and can only be counted in broken cells, but they are
nevertheless useful in establishing a diploid count. Figure 1 is of a
spermatogonial phase, and shows 21 chromosomes.

Prophase events are also not easily analyzed in the Heteroptera
(Ueshima 1979), but are useful in establishing the size and shape of the
sex chromosomes. Figures 2 and 3 clearly show a single heteropyconotic
chromosome (the X chromosome).

Cells which are found in early diakinesis show chiasmata formation
among the autosomes. Figure 4 shows terminalization of chiasmata
among homologs of each of the autosomes. The microchrosomes (m) are
plainly visible as the two smallest chromosomes. The X chromosome (x)
can now be determined by comparison with Figures 2 and 3. Nine
homolog pairs can be seen, as can the X chromosome and the two
microchromosomes. Figure 5 shows late diakinesis, when terminalization
of chiasmata is complete and the autosome homologs have reached their
maximal lengths for this stage. This stage was the most useful in estab-
lishing a count. Thus, in L. zonatus we clearly see 9 pairs of autosomes,
the X chromosome, and two microchromosomes, for a total of 21.
Chromosomes were measured in 7 cells in late diakinesis. Two of the
autosome homolog pairs were consistently larger than the rest, 4-5 microns
in length. The remaining autosome pairs and the X chromosome were 2-
3 microns in length, and the microchromosomes (which are round) were
1 micron in diameter.

In metaphase I (Figures 6 and 7), the autosome pairs and the X
chromosome formed a ring around the two closely appressed micro-
chromosomes. Finally, in a metaphase II (Figure 8), the same type of ring
formed around the single diffuse microchromosome.

DISCUSSION

Other species of Leptoglossus have been looked at cytologically,
including L. dilaticollis Guerin (Piza 1956), L. gonagra (Fabricius) (Piza
1945),L. phyllopus (Linnaeus) (Wilson 1 909), and L. stigma (Herbst) (Piza
1956). All have a diploid complement of 21 chromosomes in the male
(ISA + 2m + X). Leptoglossus zonatus, therefore, falls into this already
established pattern.

These observations do not depart significantly from the more detailed
description of meiotic events in Coreus marginatus L. (a member of the
tribe Coreini) (Nokkala 1986); but the procedure and drawings herein
should provide a novice entry into this neglected field of cytology. Only
chromosome numbers were reported in all previous studies of this genus.
It is hoped that the brief characterization of meiotic events within this
species and the finding of disparate chromosome sizes will prove to be
of value in further analysis of the cytology and the complex evolutionary
history of this diverse and cytologically poorly known family.
