1. PENTANEURINI (TANYPODINAE)1




WILLIAM M. BECK, JR., AND ELISABETH C. BECK 2 \ \







SYNOPSIS: The Florida Chironomidae of the tribe Pentaneurini (as defined by
Fittkau, 1962) were studied from specimens collected in the wild and reared in
the laboratory. The 27 species reared are placed in 11 genera; larvae, pupae,
and adults are described and diagnostic characteristics defined. Information on
methods and ecological data are included. The following 17 new species are
described: Ablabesmyia philosphagnos, A. hauberi, A. ornata; Pentaneura in-
culta; Guttipelopia currani; Monopelopia boliekae, M. tillandsia; Labrundinia
floridana, L. neopilosella, L. johannseni, L. virescens; Paramerina anomala; Con-
chapelopia fasciata, C. gigas; Nilotanypus americanus; Larsia berneri, L. lurida,
L. indistincta; and Arctopelopia fittkaui.
The following taxonomic changes are noted: Pentaneura janta, P. peleensis,
P. aspera, P. auriensis, P. annulata, P. cinctipes, P. prudens, P. aequifasciata, and
P. mallochi are now species of the genus Ablabesmyia. Pentaneura pilosella is
Labrundinia pilosella, and Pentaneura carnea (of Johannsen, not of Fabricius) is
now Zavrelimyia carneosa Fittkau.

INTRODUCTION

For the past four years we have made a study of the Chironomi-
dae of Florida to delineate what species comprise the fauna, their
seasonal and geographical distributions, their ecology, and life his-
tories.
During the last two years we have emphasized collecting and rear-
ing specimens of the tribe Pentaneurini as defined by Fittkau (1962).
He divides this tribe, comprised of species formerly placed in the
various groups of Pentaneura and some formerly in Anatopynia, into
18 genera. We have reared 27 species from Florida belonging to 11
of these genera, and collected as adults, but not reared, an additional
three species. Of these 30 species, 19 are apparently undescribed.
This paper describes the larva, pupa, and adult of all reared species,
and gives ecological data on the larval habitats.
The following list includes all previously described North Ameri-
can species of Pentaneurini, referred as far as possible to Fittkau's
genera.

fastuosa (Johannsen)
Macropelopia sp. 1 and sp. 2 of Roback (1957)

listed no North American species. As yet no species have been reared
or recorded definitely referable to his genera Trissopelopia, Xenope-
lopia, or Telmatopelopia.
METHODS
During this study we took 185 collections totaling 16,566 larvae
from different streams, rivers, ditches, ponds, and lakes in Florida.
Most collections contained some Pentaneurini; many were almost
entirely of this tribe.
Collections were made by pulling a D-frame dipnet along the
bottom or through vegetation of a body of water. The contents were
put into a shallow white enamel pan and flooded. Larvae were
pipetted singly into small (2 dram) vials of water from the collecting
site, stoppered, and placed in trays in a styrofoam ice chest to be
taken to the laboratory. Records were kept on each larva, noting
time until pupation, length of pupal stage, date of emergence, and
any notes of interest. The adult was slide mounted or pinned, and
the larval and pupal skins slide mounted for identification. Attempts
to feed the larvae with artificial media were largely unsuccessful and
emergence was unlikely unless pupation occurred within five days
of collecting. Adults emerged from 25 to 30 percent of the larvae
collected.
Holotype specimens of new species described in this paper are
deposited in the United States National Museum. Paratypes, where
enough good specimens are available, are in the Florida State Col-
lection of Arthropods, in the collection of the Florida State Board
of Health, and the Hydrobiologische Anstalt der Max-Planck-Gesell-
schaft, Plon, Germany. All reared specimens of new species listed
in this paper are paratypes.
In describing adults the following abbreviations are used: WL
(wing length), measured from attachment at thorax to apex of wing;
AR (antennal ratio), length of two apical segments of male antenna,
divided by combined length of remaining segments; LR (leg ratio),
length of fore basitarsus divided by length of foretibia. In larvae
AR is the length of basal segment of antenna divided by the length
of the remaining segments.

COLLECTION SITES
Though collections were made at a large number of different sites,
most of the collections containing Pentaneurini were made at 14
sites in 11 counties. Descriptions of stream typology for each site
follow Beck (1965).

BULLETIN FLORIDA STATE MUSEUM


Duval County- Expressway creeks, north of junction with U.S. 1.
Several small streams were sampled at various times along a 5
to 6 mile stretch of this road. These streams have either mud or
sand and organic detritus bottoms; color is high, turbidity low,
velocity low to moderately swift; they range in depth from 6-18
inches and support a heavy growth of algae, Utricularia and Sphag-
num.
The chironomid fauna consists of Tanytarsini, Clinotanypus
thoracicus (Loew), Tanypus spp., Procladius spp., Psectrocladius sp.,
Corynoneura (C.) sp., Cricotopus bicinctus (Meigen), Chironomus
dorsalis Meigen, C. modestus Say, C. hirtalatus Beck and Beck, Con-
chapelopia fasciata n. sp., Larsia herneri n. sp., L. lurida n. sp., L.
indistincta n. sp., Ablabesmyia aspera (Roback), A. peleensis (Walley),
Labrundinia virescens n. sp., and Arctopelopia fittkaui n. sp.

Duval County-Beach Boulevard streams.
This site has two small streams running within a few hundred
feet of each other. One was originally swift and clear with sand
and detritus bottom and only marginal vegetation: Azolla, Vallis-
neria, and Pontederia. The other stream was canal-like, of no per-
ceptible flow, and polluted by the effluent from a nearby sewage
treatment plant; it was an opaque gray-green from dense algal and
Sphaerotilus growths. During the period of this study the effluent
was apparently diverted to the clean stream, and the two have
almost reversed ecological characteristics. For this reason data from
the two streams have been combined.
The following chironomids have been reared from these streams:
Cricotopus bicinctus, Tanytarsini, Corynoneura (Th.) spp., Ortho-
cladius spp. Psectrocladius spp. Chironomus collator (Townes), C.
casuarius (Townes), C. hirtalatus, Clinotanypus pinguis (Loew), Poly-
pedilum illinoense (Malloch), Stenochironomus cinctus Townes, Abla-
besmyia aspera, A. janta (Roback), A. peleensis, Guttipelopia currani
n. sp., and Larsia berneri n. sp.
Alachua County- Hatchet Creek.
This is a fairly large typical sand-bottomed stream; it is mod-
erately swift, color is high, turbidity low. It supports a moderate
to occasionally heavy growth of plants along the banks, including a
few Polygonum.
The chironomid fauna includes: Polypedilum illinoense, P. para.
scalaenum Beck, Nilothauma biconis (Townes), Cricotopus bicinctus,
Tanytarsini, Psectrocladius sp., Orthocladius sp., Chironomus (Cryp-

to.) sp., Ablabesmyia auriensis (Roback), A. janta, A. ornata n. sp.,
Pentaneura inculta n. sp., Labrundinia pilosella (Loew), and Larsia
berneri n. sp.

Clay County Black Creek.
This is a moderately swift sand-bottomed stream, with logs and
dead brush; several prongs of the creek were worked and vegeta-
tion ranged from very few plants to moderate growths of Vallisneria,
Nymphaea, Saururus, Hydrocotyle, Polygonum, grasses and algae.
During the cooler months heavy growths of the red alga, Batracho-
spermum, were present.
The following species of chironomids have been reared from the
Black Creek drainage: Polypedilum illinoense, P. parascalaenum, P.
convictum (Walker), P. (Pentapedilum) sp., Trichocladius robacki
Beck and Beck, Orthocladius sp., Cricotopus sp., Chironomus jucun-
dus Walker, Chironomus sp. (near dux), Tanytarsini, Corynoneura
(Th.) spp., and Ablabesmyia auriensis.

Clay County Peter's Creek.
This small sand-bottomed creek in the Black Creek drainage
basin is treated separately as a collecting site because of its varied
and distinctive fauna. It is moderately swift, high in color, low in
turbidity, and has a moderate to dense plant growth: Vallisneria,
red and green algae and others. We collected several species of
chironomids from this little creek that we took at no other location.
The following species have been reared from Peter's Creek: Cory-
noneura (C.) sp., C. (Th.) sp., Tanytarsini, Trichocladius robacki,
Cricotopus bicinctus, Metriocnemus lundbecki Johannsen, Polypedi-
lum convictum, P. parascalaenum, Chironomus jucundus, Apsectro-
tanypus johnsoni (Coquillett), Orthocladius sp., Stenochironomus
(Walker), Ablabesmyia peleensis, A. hauberi n. sp., Nilotanypus amer-
icanus n. sp., Conchapelopia gigas n. sp., Pentaneura inculta n. sp.,
Paramerina anomala n. sp., and Labrundinia floridana n. sp.

Indian River County Bromeliads at Vero Beach.
Water accumulating at the base of the leaves of epiphytic brome-
liads is known to harbor a number of insect larvae. The bromeliad,
Tillandsia utriculata L., at the Entomological Research Center at
Vero Beach was examined on. three occasions for larvae. These
species were found: Metriocnemus abdomino-flavatus Picado, Tany-
tarsini, and Monopelopia tillandsia n. sp. The water contained plant
and animal detritus.

The Fenholloway River, physically a sand-bottomed stream, chem-
ically a swamp-and-bog stream, receives the effluent from a kraft
paper mill about 3 miles downstream from the sampling station.
It is dark brown (750 ppm color in July), turbidity low, bottom of
sand, rock, silt, and logs. Vegetation consists mainly of grasses,
Panicum, Hydrocotyle, and a few Eichornia crassipes. Chironomid
larvae found here include: Polypedilum parascalaenum, P. convictum,
P. illinoense, Trichocladius sp., Clinotanypus thoracicus, Chironomus
fucundus, C. emorsus (Townes), C. near fulvus, Tanytarsini, Abla-
besmyia janta, and Conchapelopia fasciata n. sp.

Jefferson County- Lake Miccosuckee.

abortivus, C. potamogeti (Townes), Tanytarsini, Ablabesmyia peleen-
sis, Guttipelopia currani n. sp., Larsia berneri n. sp., and L. lurida
n. sp.

Flagler County Rayonier Ditch.
Rayonier Ditch, running from U.S. 1 to the Intracoastal Water-
way and draining an area of pine flatwoods and swamp, presents a
number of quite different habitats. Almost without velocity in cer-
tain areas, it becomes quite rapid in small falls over coquina near the
Waterway. Color is high, turbidity low. Areas are densely vege-
tated with Utricularia, Pontederia, Limnobium, and algae. Chirono-
mids reared from this ditch are: Orthocladius sp., Tanytarsini, Psec-
trocladius sp., Cricotopus bicinctus, Corynoneura (C.) spp., C. (Th.)

Ablabesmyia Johannsen

This is the genus of Pentaneurini encountered most commonly
in Florida, both in number of species and number of individuals.
Adults are bicolored and wings are patterned, but the differences in
species are subtle and often they can be separated with certainty
only on the basis of the male genitalia.

CHIRONOMIDAE (DIPTERA) OF FLORIDA


Adults of this genus are differentiated by the following character-
istics: the dorso-lateral (acrostichial) setae of the mesonotum are
divergent around the prescutellar area; the foretibia has three or
more dark rings; the base of the basistyle forms a hollow which con-
tains strongly differentiated structures; the spine of the dististyle is
subapical. The larvae have an antennal ratio of at least 4; the head
and body surfaces are smooth; anal gills slender and about 1/ as
long as the prolegs; proleg claws simple, usually one or more dark-
ened. The pupae are distinguished by having round or ovate respir-
atory organs with a row of spines at base of each organ, not unlike
that of Guttipelopia.
Descriptions of immature stages of North American Ablabesmyia
are found primarily in the following publications: Malloch (1915),
Johannsen (1937), Hauber (1945), Roback (1957), and Sublette (1964).

Within "A. peleensis" is a group of specimens that run, in gen-
eral, larger and darker. This material is not considered describable
at present.
MALE: WL 1.9 2.2 mm.; WL in females 2.2 2.4 mm. The abdo-
men is usually somewhat infuscate, more so in females, but we can
find no clear-cut characteristics to separate them as adults; wing
patterns are not very clear, somewhat as in A. illinoiensis as illus-
trated by Walley (1928). For the present we are including these
specimens with A. peleensis. The larval ratio is highest in this group
of larger specimens (5.8 6.6), the pupal casts are 5.0 5.8 mm. long,
and respiratory organs range from 0.47 0.60 mm. long.

with the three median teeth much shorter (median shortest), pale at
tip; anal papillae brown, 3.5 times long as wide; two dark claws on
posterior proleg; maxillary palpus with five basal segments.
PUPA: Cast skin 3.6 mm. long, light brown with a distinct and very

blackish, duct not abruptly widened at apex; seven large and three
smaller round-tipped spines; anal fin 1.2 times long as wide; male
genital sac three-fourths as long as fin.
The median band of foretibia being at the middle eliminates these
species: A. annulata, A. cinctipes, A. auriensis, A. mallochi, and A.
prudens; the wing pattern eliminates A. idei and A. basalis; the num-
ber of larval palpal segments excludes A. americana, A. rhamphe,
and A. janta; and the much smaller size eleminates A. aspera and
A. aequifasciata.
This species has been collected and reared from:

LARVA: AR 5, sensory pit at 0.59. Head capsule is brownish-yellow
with a conspicuous dark brown rectangle on apex ventrally and small
brown median spot near posterior border ventrally; maxillary palpus
with five or six basal segments; lingua has the three median teeth
shorter and light at tip; at least 15 teeth on supralingua; anal papillae
2.5 3.0 times long as wide, pale gray; posterior proleg has one short
dark brown claw and one longer claw is very slightly brownish.
PUPA: Cast skin is 4.2 mm. long, light brown with very faint pat-
tern; respiratory organ medium brown, 0.31 mm. long by 0.15 mm.
wide, 10 bluntly pointed spines of varying sizes and three very small
spines at base, duct not abruptly widened at apex; anal fin 1.3
times long as wide, male genital sac three-fourths long as fin.
The median band of foretibia being midway eliminates; A. annu-
lata, A. cinctipes, A. auriensis, A. mallochi, and A. prudens; number
of larval antennal segments eliminates A. americana, A. rhamphe,
and A. janta. This species is also very similar to A. acfquifa.sciata,
but the genitalia are quite different. A great deal of study and col-
lecting will be necessary before the exact taxanomic positions of
A. hauberi, A. inalhoci, A. aequifasciata, and A. auriensis can be
finally determined.
A. hauberi has been collected and reared from:
Flagler County Rayonier Ditch in May 1964 holotypee, allotype,
1S, 19).
Clay County Peter's Creek in January 1965 (19).
Larvae were collected at the following locations, but not reared:

ments 6 8 entirely blackish-brown. Dark bands of tibia are very
narrow, about equal to tibia diameter; middle band of foretibia is at
0.58 from base of segment and midway between the other two dark
bands; fifth tarsal segment on all legs and most of fourth segment on
foreleg dark. Spot in cell M is basal to spot above in cell R. No
bulge at base of basistyle, genitalia pale; aedeagal blade very small,
about three-fourths as long as the narrowed apex of dististyle; sub-
apical stylet of dististyle acute at tip as in A. peleensis, not flared as
in A. americana.
FEMALE ALLOTYPE: St. Johns County, Florida, roadside ditch, Feb-
ruary 6, 1965. WL 2.1 mm. Antenna grayish, last segment all black-
ened. Marked as in male, except abdominal tergites all with broad
basal dark fasciae, sternites dark.
LARVA: AR 5.8; larva very pale, apex of mandible black; teeth of
lingua amber, all else pale. Maxillary palpus with two basal seg-
ments (12:22), sensory pit at 0.51 from base; lingua with three
median teeth shorter, middle one shortest; supralingua with 16 teeth;
all claws of posterior proleg pale, one short claw is slightly darker
amber, one claw has apex bent at right angles to base; anal papillae
three times long as wide. This is the only described North American
Ablabesmyia that lacks black or dark brown claws on the posterior
prolegs.
PUPA: Cast skin 5.1 mm. long, pale yellow; shape of opercula dis-
tinctive (see Plate 14, fig. 4); respiratory organ 0.58 mm. long by
0.25 mm. wide, apex of respiratory duct forms a rounded "T"; four
large, sharply pointed spines and six tiny spines at base of respiratory
organ; anal fin 1.2 times long as wide, male genital sac three-fifths
as long as fin.
The acute stylet of dististyle eliminates all described species
except A. cinctipes (five dark bands on foretibia), A. peleensis (duct
of respiratory organ of pupa), and A. illinoiensis. The wing markings
of this species are very similar to those of paratype #18799 A. illi-
noiensis, but the following obvious differences exist: Malloch's (1915)
original description says "The basal joint of the foretarsus is slightly
longer than the next two joints together .... In A. philosphagnos
the forebasitarsus has a ratio to the next two tarsal segments to-
gether of 10: 11.6.
The pupa of A. illinoiensis is described in Malloch's key: "Apex
of pupal respiratory organ without distinct aperture and with a long
conspicuous hair. . A. philosphagnos has a very distinct aper-
ture, but no long hair. Malloch says A. illinoiensis pupa has 8- 10

short tubercles at base of respiratory organ; this new species has
4 5 large, sharply pointed spines and 4 -9 much smaller spines.
Specimens recorded as A. illinoiensis by Beck and Beck (1959) do
not agree with the paratype #18799 in leg markings and other char-
acters; they probably represent a closely related, undescribed species.

side ditch in St. Johns County- State Road 210 in February 1965

Guttipelopia Fittkau
The species placed in the genus Guttipelopia are those formerly
in Edwards' Pentaneura (Group B), characterized by having wings
with numerous whitish hyaline spots on a gray ground color; C ex-
tending scarcely beyond R4+, and ending proximal to M; R2+3 in-
distinct; m-cu about its length proximal to r-m; no pulvilli; tarsi not
bearded. The larva has anal gills short, curved like a horn, and reach-
ing only about a seventh of the proleg length. The head capsule is
roughly granular and there are wrinkling undulations the length of
the body surface. The pupa has an oval respiratory organ with an
apical papilla containing a rather long duct; there is a dark brown
horn-like projection mid-dorsally on the thorax.
Fittkau (1962) lists G. guttipennis for Europe, G. multipunctata
for North America. The figures given in Fittkau (1962) and in
Goetghebuer (1927) for G. guttipennis pupae differ chiefly from
Florida specimens in that the pupal respiratory organ figured has
a much shorter duct at the apex than has G. currani n. sp. In Hau-
ber (1946), Pentaneura "guttipennis" from Iowa are said to have all
femora pale, with the apical fourth darkened; our specimens have
gray femora with apical half pale except for a dark subapical band.
Curran (1930) describes Tanypus multipunctatus from a female, and
it would be difficult to state positively that this is not the species we
have without seeing the holotype, but his description also says: "legs
yellowish; broad apex of femora . brown."

all pale; there is a cluster of five or more heavier setae at the apex
of first palpal segment.
LARVA: AR 3.8, sensory pit at 0.5, whole antenna somewhat brown;
lingua has the three median teeth slightly shorter and distinctly
lighter at apex; basal segment of maxillary palpus four times long
as wide; all claws of posterior proleg are pale, some serrate; one

This species has been collected only from bromeliads in Indian
River County Vero Beach in May 1964 holotypee, 18, 19). The
larvae have been kept alive in the laboratory for 107 days in water
from the plants where they were found.
The only other species of Pentaneurini reported from bromeliads
is Isoplastus (=Ablac1(siijyia) costarricensis Picado (1913). Because
of the limitations of the original description, we are unable to place
this species in one of Fittkau's genera, but it differs in a number of
characteristics from Monopelopia tillandsia, notably in the shape
of the respiratory organ of the pupa, and the number of lateral fila-
ments on the eighth segment of the pupa.

Labrundinia Fittkau
Adult Labrundinia are characterized as having C ending above
or before Cul, R2+3 missing or poorly formed, m-cu double its length
proximal to r-m; adults brownish to brown, with patterns on thorax
and abdomen; no mesonotal tubercule; tarsi of middle leg with sole
spines; inner spur of middle tibia scarcely visible, inner spur missing
on hind tibia; fore tibia not bearded, mid and hind tibiae scarcely
bearded; ninth tergite of male arched with an apical row of long
setae.
Fittkau's characterization of the larvae is based on the only well-
described species and is not entirely applicable to the whole genus;

he says the larva has the middle tooth of lingua very large, extend-
ing far beyond the other teeth; in two of the species in this paper the
outer lateral is about as long as the median tooth. He says the
second antennal segment not darkened; in all species included here
the second antennal segment is darker than the first, at least basally.
In L. floridaJi n. sp. the head capsule is entirely nodulate.

BULLETIN FLORIDA STATE MUSEUM


From Johannsen's meager description we cannot tell if the two
females we reared are the same species he had from New York.
Fittkau (1962) states that exuviae of Nilotanypus collected in North
America by Brundin probably belong to P. dubius of Johannsen, but
is not the same as P. dubius (Meigen).
This species has been reared only from Clay County, Peter's
Creek, collected in February holotypee) and March (9 paratype)
1963.
Conchapelopia Fittkau
The genus Conchapelopia is in Fittkau's Thienemannimyia series
which also includes Arctopelopia, Rheopelopia, and Thiehemanni-
myia. Conchapelopia is generally pale with basal abdominal bands;
there is a tuft of 8 10 large strong setae (about 1.5 times as long as
the tibial diameter) at the apex of the third tarsal segment of the
middle leg; the femor is not, or is only indistinctly ringed near apex;
the crossveins are pale; R2+3 well-formed, C ends just before or above
apex of M. The thorax bears a small median tubercule. The basi-
style of the male genitalia is flattened, hollowed out dorsally with
2-8 large dorso-medial setae near insertion of the dististyle; the
lobe of the basistyle is strongly differentiated, about two-thirds as
long as the basistyle; the dististyle is distinctly broadened distally.
The species of this genus are very similar and difficult to separate as
larvae or adult females, though the male genitalia and pupal respira-
tory organs are usually quite distinctive. The female antenna has
12 segments.

The above keys make it evident that the separation of the species
of this genus is not easy; L. indistincta and L. lurida may represent
extremes of the same species, but without intergrading material on
hand for study they appear quite different, especially in the pupal

PUPA: Cast skin 3.2- 3.8 mm. long; respiratory organs 0.20 0.26
mm. long; anal fin 1.7 2.0 times long as wide. All segments spicu-
late; second segment with crescent-shaped rows of longer pale
spines.
L. lurida appears to agree in most characteristics with T. decolor-
atus, but Malloch's figure for the male genitalia is quite unlike that
of L. lurida. If Morrissey (1950) is correct in his figure for the pupal
respiratory organ, of P. planensis, that 'species is probably not a
Larsia.
L. lurjda has been collected and reared from:
Leon County Boliek's Pond in May and June 1964, May 1965 (allo-
type, 19, 1 $), and April 1963 (1 a); roadside pond in May 1964

and a very small clear apico-medial spot; 12 or more round-tipped
spines at base of respiratory organ which is 0.21 0.23 mm. long;
segments are spiculate, especially the second and eighth; second seg-
ment has crescent-shaped rows of longer pale spines; anal fin is
1.6 1.8 times long as wide.
L. indistincta agrees with T. decoloratus in many particulars,
but the male genitalia and the larval lingua are different. Roback
(1957) describes as Pentaneura poss. curticalcar (Kieff.) a larva which
may be L. indistincta.
This species has been reared from the following:
Leon County- roadside pond in May 1964 (19).
Flagler County Rayonier Ditch in February 1965 (allotype).
Jefferson County- Lake Miccosuckee in May 1965 (1 ).
Polk County Green Swamp in March 1965 holotypee).

ECOLOGY OF LARVAE
As mentioned in the introduction, most of the taxonomy and part
of the ecology of the Pentaneurini of Florida described here are
based on material reared in the course of this study. In addition
we have available a great number of larvae collected during routine
stream and lake surveys and investigations of many different types
of special habitats throughout the State. Part of the purpose of
the study was to increase our knowledge of the immature stages of
these insects. This could best be done by rearing larvae and identi-
fying the adults, giving us larval and pupal material associated with
described adults. It was then possible to examine and identify pre-
served larval material, increasing our knowledge of the ecology and
zoogeography of the species involved through the acquisition of-
in many cases-literally scores of additional distribution records.
Species confined to flowing waters are: Pentaneura inculta, Para-
merina anomala, Nilotanypus americanus, Labrundinia floridana, L.
pilosella, Ablabesmyia auriensis, and A. malochi.
Typically found in standing waters are Ablabesmyia philosphag-
nos (generally in growths of Sphagnum, but always in dense growths
of submerged vegetation), Monopelopia boliekae, and M. tillandsia
(from a single species of Tillandsia).
Ubiquitous 'species include Ablabesmyia peleensis (the most com-
mon and widely distributed species of the tribe Pentaneurini in
Florida), A. aspera, A. hauberi, A. janta, A. ornata, Guttipelopia

currani, Labrundinia virescens, L. neopilosella, L. johannseni, and
all species of Larsia and Conchapelopia.
Because of their rarity little can be said of the ecology of Zavreli-
myia carneosa, Arctopelopia fittkaui, and Natarsia fastuosa. We have
not collected larvae of N. fastuosa.
During this study approximately 10 gynandromorphs have been
reared. All of these were of the same type: female antennae and
body build, with male genitalia; in each a large mermithid worm
was coiled in the distended abdomen. We have observed two types
of parasitization: one in which the worm leaves the body of a mature
larva, resulting in the death of the larva; a second type in which the
parasitized larva develops into an active adult, although generally
a gynandromorph. Gynandromorphs of the following species have
been reared: Guttipelopia currani, Ablabesmyia peleensis, A. hauberi,
and A. philosphagnos.

ZOOGEOGRAPHY
At the present time knowledge of the chironomid fauna of North
America is too incomplete for any profound discussion of distribu-
tions of species. The particular tribe covered in this paper has, how-
ever, attracted the interest of several North American workers and
has, consequently, received considerable attention. Zoogeographi-
cal discussion of this tribe is therefore of some significance at the
generic level.
Dr. Ernst-Joseph Fittkau recently spent several days with us,
examining our material and discussing at great length the distribu-
tions of the genera involved. These discussions, combined with the
material in his excellent monograph (Fittkau, 1962), have been
of great help in understanding the origin of the fauna. Additionally
helpful was his great personal knowledge of holarctic and tropical
faunas.
The Pentaneurini of Florida at the generic level may be di-
vided into several more or less distinct groups insofar as derivation
of the fauna is concerned. Of seven holarctic genera four are found
in Florida, each represented by a single species. These species are:
Natarsia fastuosa, Arctopelopia fittkaui, Guttipelopia currani, and
Zavrelimyia carneosa.
The genus Labrundinia is considered by Fittkua to be subtropical
and tropical in origin. Five species are known in Florida at the
present time.
The genus Pentaneura (sensu Fittkau) is believed to be of South


354

American origin and is represented in Florida by a single species.
The immature stages of this species are very distinctive, widely dis-
tributed in Florida and, it appears at present, may well be mono-
typic within the State.
At present several genera appear to have rather discontinuous
worldwide ranges, a result most probably of discontinuity of areas
studied. These include Conchapelopia (holarctic and tropical), Mon-
opelopia (Europe and Indonesia), and Nilotanypus (holarctic and
Ethiopian). Genera listed by Fittkau as confined to Europe (Tel-
matopelopia and Xenopelopia) have thus far not been found in Flor-
ida, nor have the two holarctic genera Thienemannimyia and Rheo-
pelopia.
By far the greatest number of species of any genus in Florida-
12--belong to Ablabesmyia, listed by Fittkau as worldwide in dis-
tribution.
The subject of endemism must be handled with caution. Six
species possibly endemic to Florida are: Paramerina anomala, Nilo-
tanypus americanus, Conchapelopia gigas, Monopelopia boliekae, M.
tillandsia, and Ablabesmyia philosphagnos. Of these the most prob-
able endemic species are: P. anomala and N. americanus, both of
which have been reared only from a small stream in Clay County.
C. gigas also has been reared only from this same small stream and
light trap records suggest a very limited distribution within the State.
Larvae of the genus Conchapelopia are very widespread and com-
mon in Florida, but cannot be separated with certainty at present,
hence the more cautious listing among the endemic species. Mon-
opelopia tillandsia may well prove to be a tropical species that has
been introduced into Florida since the specific host plant is widely
distributed in Central America and the West Indies. Recently the
Public Health Service sent us some preserved chironomid larvae
collected from treeholes in areas surrounding the Miami International
Airport. Among these larvae were several specimens of the genus
Monopelopia differing from both Florida species and not further
identifiable. This also may represent an introduced tropical species.
The chironomid fauna of the West Indies is almost totally unknown
and that of Central America poorly known.
Zavrelimyia carneosa deserves special mention. This species is
quite widely distributed in temperate North America. A few adults
that may possibly be this species have been taken from light traps
in several areas of Florida but, as is so often the case with light trap
material, were in too poor shape to identify positively. It is of in-
terest that of many thousands of larvae collected from all types of


1966

habitats in Florida during the past 15 years, larvae of Z. carneosa
have been found only in a ravine on the Caldwell plantation near
Tallahassee. This ravine is deep and densely shaded, roughly cir-
cular in shape, with many small springs and seepage areas around
the periphery that drain into a small creek which flows out the
open end of the ravine.. It is quite possible that this population is
relict and the only population of this species in the State.
Peter's Creek,, mentioned frequently above, is one of many such
small streams comprising the Black Creek drainage in Clay County,
the latter a tributary of the St. Johns River. This complex of streams
is almost totally unaffected by the activities of man. Representatives
of several groups of aquatic organisms found here do not occur else-
where in Florida east of the Apalachicola drainage. For many years
we have believed that the Black Creek drainage is a relict area and
the evidence of the tribe Pentaneurini lends further credence to this
belief.
In summary it appears that Florida's Pentaneurini population
migrated into the State largely from the north or northwest, with a
significant portion of the fauna migrating from tropical America and
the West Indies. Apparently six species, but no genera, are endemic
to Florida.

Contributions to the BULLETIN OF THE FLORIDA STATE MUSEUM may be in any
field of biology. Manuscripts dealing with natural history or systematic problems
involving the southeastern United States or the Caribbean area are solicited
especially.
Manuscripts should be of medium length-50 to 200 pages. Examination for
suitability is made by an Editorial Board.
The BULLETIN is distributed worldwide through institutional subscriptions and
exchanges only. It is considered the responsibility of the author to distribute his
paper to all interested individuals. To aid in this, fifty copies are furnished the
author without cost.

PREPARATION OF MANUSCRIPT

Highly recommended as a guide is the volume:
Conference of Biological Editors, Committee on Form and Style.
1960. Style manual for biological journals.
Amer. Inst. Biol. Sci., Washington. 92 p.
Manuscripts should be typewritten with double spacing throughout, with ample
margins, and on only one side of the paper. The author should keep a copy; the
original and a carbon must be submitted. Tables and legends of figures should
be typed on sheets separate from the text. Several legends or tables may be
placed on a single sheet.
Illustrations, including maps and photographs, should be referred to as "figures."
All illustrations are reduced to a maximum of 4-1/4 by 7-1/8 inches. Size scales,
wherever they are necessary, should be incorporated into the figure.
References to literature should conform with the bibliographic style used in recent
numbers of the BULLETIN. Spell out in full the titles of non-English serials and
places of publication.
Footnote material should be kept to a minimum. However, provide copy for a
footnote detailing the title, affiliations, and address of the author (see recent num-
bers of the BULLETIN).
Manuscripts must be accompanied by a synopsis-a brief and factual summary
(not a mere description) of the contents and conclusions, which points out the
presence of any new information and indicates its relevance. In it list all new
organisms described and give their ranges; indicate all taxonomic changes pro-
posed. The synopsis, written in full sentences, should be concise, but completely
intelligible in itself without references to the paper, thereby enabling the busy
reader to decide more surely than he can from the title alone whether the paper
merits his reading. The synopsis will be published with the paper. It does not
replace the usual conclusions or summary sections. It may also serve as copy
for the abstracting services.
Manuscripts and all editorial matters should be addressed to:
Managing Editor of the BULLETIN
Florida State Museum
Seagle Building
Gainesville, Florida
