CHIRONOMIDAE (DIPTERA) OF FLORIDA
III. THE HARNISCHIA COMPLEX (CHIRONOMINAE)'

ELusA Bm C. BECK AND WILLAM M. BECK, JR.2

SYNOPSIS: Reared chironomids from Florida, which American authors have
classified as belonging to the genera Cryptochiroiomum or Harnischia, were
studied and placed in four genera described by EurpPearn 'thors.
Larva, pupa, and adult of each species are described, t l in classifying the
16 Florida species the following taxonomic changes. are uited .Tendipes tenuicau-
datou, Chironomus directs, Chironomus sublettel, Hq e4sshid cainata, Chironomus
hrtalatus, Tendipes pectinatelae, and Chironomiiiuals t are'now placed in the
genus Parachironomus. Harnischia casuaria.is pide a species of the genus
Cryptotendipes, and Chironomus undine is plal~id hatr genus Paracladopelma.
Two new species are described: Parachironomus schneideri and Paraclado-
pelma loganae.

INTRODUCTION
Although the taxonomy of the Chironomidae has been in a con-
fused state for some time (Beck and Beck, 1966, 1968; Fittkau, 1968),
probably the greatest variety of taxa has been proposed for those
species that American authors have classified under Cryptochironomus
or Harnischia. These are the Chironomini with the appendages of
the male genitalia greatly reduced or absent. The anal point is present;
appendage 2 is absent or present as a small lobe, usually without
macrotrichia; appendage 1 is lobe-shaped (rounded at the apex), rod-
shaped (long, slender, with apex flat or excavated), or apparently
lacking.
The taxonomy of these groups has been handled seemingly in three
ways 1) Putting all these species in the genus Chironomus, subgenus
Cryptochironomus, and making no further breakdown except species.
This follows Freeman (1957), and was the procedure adopted by
Sublette and Sublette (1965). 2) Separating the species into the gen-
era Cryptochironomus s.s. and Harnischia (with two or more sub-
genera), as was done in Townes (1945). 3) Classifying the species
into a number of different genera, as proposed by European workers,
principally Lenz.
As our studies with reared specimens show distinctive morpho-
logical characters in all three life stages of the groups we have in-
cluded, and as we feel these different characters of generic importance,
we have adopted the European concept and give these groups generic
rank in this paper.
We do find, however, that some of the genera we are dealing
with have, in the immature stages, many characters in common with
Chironomus (Dicrotendipes), and in other stages appear to be especially
close to other chironomid genera. This makes it difficult, if not im-
possible, to draw straight-line relationships. We are placing the Flor-
ida species that we have reared into the following genera: Crypto-
chironomus Kieffer, Parachironomus Lenz, Paracladopelma Harnisch,
Cryptotendipes Lenz, and Harnischia Kieffer (= Cryptocladopelma
Lenz). We feel that Demicryptochironomus Lenz and Microchirono-
mus Kieffer (= Leptochironomus Pagast) are also valid genera, but
none have been reared from Florida.
The species falling into Crytochironomus will be dealt with in a
later paper, but the genus is included in keys to the genera because
its similarity to the genera under consideration requires that we be
able to differentiate it clearly.








1969 BECK/BECK, JR.: FLORIDA CHIRONOMIDAE 279

Sublette and Sublette (1965) list 53 species under Chironomus
(Cryptochironomus); of these only 6: argus Roback, blarina Townes,
digitatus (Malloch), fulvus (Johannsen), psittacinus (Meigen) and
scimitarus Townes are Cryptochironomus s.s. The remaining 46 will
probably fall into the genera discussed in this paper.
Abbreviations follow those of Dendy and Sublette (1959). Wing
length is measured from the basal arculus to wing apex. Antennal
ratio of larvae is expressed as the proportions of the segments. Holo-
types of new species are deposited in the United States National
Museum. Paratypes, where available, are deposited with the Florida
State Collection of Arthropods, Gainesville, Florida, and in the au-
thors' collection.

Pagast, 1931: 209, 213-216; Johannsen, 1937: 20.
ADULT: Very generally, adults of this genus are larger and heavier
bodied than adults of the other genera under consideration here.
The dististyle of the male genitalia is more or less angular at apex
and fairly short, the appendages are small, rounded, about equal in
size, both densely pubescent and with several bristles. The presence
of bristles on appendage 2 separates this genus from all other genera
considered here.
LARVA: Labial plate with wide median pale domed area and five
dark lateral teeth on each side, the outer tooth may be notched, gen-
eral shape of plate concave so that outermost teeth project anteriorly;
basal segment of maxillary palp is three to four times as long as wide;
premandibles with four to six blades; antennae five-segmented, blade
arising near apex of second segment.
PUPA: Cephalic tubercles are often very large and of distinct shapes.
Posterior hook row on tergite II usually interrupted medially; tergites
III VIII with heavy spines near posterior margin; no comb or caudo-
lateral spines on VIII. Lateral filaments on V- VIII: 4-4-4-5 usually,
but may differ in some species. Anal fins have paired tubular median
projections.

neratus Zett. [monotypic]; Lenz, 1960a: 450-463; Lenz, 1960c: 222.
ADULT: Very difficult to separate from other genera. Appendages of
male genitalia are very short and appear to overlay one another, or
to have a common base; base of anal point is broadly triangular.
LARVA: Labial plate much as in Cryptochironomus, but with seven
lateral teeth; premandibles with four blades, one of which is much
smaller; antenna seven-segmented.
PUPA: Exuvia pigmented, yellow; posterior hook row on tergite II not
interrupted medially and more than one-half as wide as segment; VIII

ment, the blade arising from apex of basal segment. Mandible with
two or three lateral teeth which are usually pointed; premandibles
with two, or sometimes three blades. Claws of posterior prolegs with
fine hairlike spines along inner margin; in some species anterior claws
are pectinate near apex.

I and/or II.
Eight species of Parachironomus have been reared from Florida:
alatus, hirtalatus, pectinatellae, sublettei, monochromus, directs, cari-
natus, and schneideri n. sp. The following species that probably belong

Beck and Beck (1964) described the immatures of this species as
Chironomus (Cryptochironomus) directs immatures. In working with
additional reared material, we find that the specimens we were for-
merly calling directs included both directs and a new species. They
differ as adults in details of the male genitalia, the dististyle of
schneideri being shorter and wider proportionally, and appendage 1
appears slightly capitate with the two setae on opposite sides, equi-
distant from the apex, much as in the European species parilis. P.
schneideri is also larger than our specimens of directs:

mens from Palm Beach Co. in August and from Lake Co. in August
and September.
Several distinctive characters of this species in all stages make it
different from all other known Florida species of the genus. It may
not belong in Parachironomus, but as it does not fit precisely any
group as yet described, we feel it best to include it here for the
present. P. alatus differs as an adult in having a broader appendage 1
covered in dense microtrichia; as a larva in shape of the labial plate
(somewhat similar to hirtalatus), antennal ratio; and as a pupa in the
median posterior spine patch on VI which suggests a mace, and the
lack of cephalic tubercles.

Genus Cryptotendipes Lenz
Cryptotendipes Lenz, 1941: 34. Genotype: Chironomus usmaensis Pagast [by
present designation]; Lenz, 1959a: 238-250; Lenz, 1960c: 207.
Although Cryptotendipes is a nomen nudum, we prefer to retain
the name rather than propose a new one. Lenz did not clearly desig-
nate a type and none has been designated since. As anomalis was
described from a female, and as the pupa of pseudotener apparently
does not have the stalked respiratory organ (assuming that Roback's
(1957: 103) description is correct), we designate Chironomus usma-
ensis Pagast as the genotype.
It has been suggested that Cladopelma Kieffer (1921: 63) (geno-
type: C. virescens Meigen [fixation by Harnisch, 1923]) may belong
in the genus Cryptotendipes and, if so, the correct name for the genus
would be Cladopelma. However, the figures that Harnisch gives for
the larva and pupa of virescens do not agree with Cryptotendipes in
that the outer labial teeth of larva are not enlarged and projecting,
and the pupa lacks the stalked respiratory organ, and seems rather
to suggest Microchironomus. We therefore feel that until it is demon-
strated that Hamisch's figures are not correct for virescens Meigen,
and that the immatures of virescens do, in fact, conform with other
species of Cryptotendipes, it is best to retain the name Cryptotendipes
for this genus.
ADULT: Appendage 1 small, somewhat longer than wide, usually with
three or more apical bristles; appendage 2 apparently lacking. Inner
margin of dististyle is distinctly notched.
LARVA- Labial plate with all teeth equally dark, median domed and
sometimes appearing broadly trilobed, with six or seven lateral teeth,
the outer two or three greatly enlarged. Antennae five-segmented,








BECK/BECK, JR.: FLORIDA CHIRONOMIDAE


rather short in most species. Paralabials long, with distinct striations.
Premandibles with two rather short blades; mandible with three
shallow flat lateral teeth. Proleg claws are simple.
PUPA: Cephalic tubercles pointed with subapical bristle. Respiratory
organ with long stalk basally, branched some distance from body,
often nearly as long as pupal body. Posterior row of hooks on tergite
II not interrupted medially. Posterior rows of coarse spines present
on tergites III-VI or VII. Spines on VI or VII may be in a mace-like
arrangement. Sternites I and/or II may have rows of pale spines, or
pale spines on lobes. VIII has a long slender curved spine on each
lateral margin about two thirds from base. Lateral filaments on V-
VIII are 3-3-3-3 in type species, but are 4-4-4-4 in known Florida
species.
Two species of this genus have been reared from Florida, casuarius
(Townes), and an undescribed species. The species of this genus
most nearly resemble those of the genus Hamischia, but the dark un-
notched median labial tooth of the larva, the long stalked respiratory
organ and the longer, slenderer spine on VIII of pupa, and the notched
inner margin of the dististyle of adult male clearly separate the two
genera.

We have experienced considerable difficulty in trying to separate
C. casuarius and C. emorsus. Johannsen's (1937: 44) description of
Chironomus (Limnochironomus) sp., which Townes suggests may be
emorsus, does not clearly differ from the above pupa, except in having
posterior spine rows on sternites II-VII, while our specimens have
them only on sternites II-V or VI.

Cryptotendipes sp.
Only one specimen has been reared (from Wakulla liver at High-
way 98, August 1967). As this specimen is imperfect we felt it best
not to describe it until others are reared. It differs from casuarius
as an adult in being larger: W.L. 1.65 mm.; A.R. 2.35; L.R. 1.75,
and in lacking the median carina of the ninth tergite of the male
genitalia. The pupa has posterior rows of broad spines on tergites
III-VIII, those on VI and VII in two or more rows, those on VIII form-
ing a round rosette-like patch. Sternite I has a row of pale spines on
each side of the midline anteriorly and a small spined lobe lateral to
each row. There are apparently no posterior rows of pale spines on
the sternites. There is a pair of conspicuous bristles on II, and two
pair on each succeeding tergite (also on each sternite?). Anal fins
each bear 22 lateral filaments. The male genitalia of this species
closely resemble emorsus, but the pupal cast of this specimen does
not agree with Johannsen's (1937: 44) description of Chironomus
(Limnochironomus) sp.

EcoLoGY
For many of the species within this group we have too few speci-
mens to indicate much of either their ecology or zoogeography, but we
do have enough records for some to show the types of water they
inhabit. The genus Demicryptochironomus appears to contain species
confined to our swiftest waters. Paracladopelma undine, P. loganae,
and H. collator have been found only in running water in Florida.
Species confined to standing waters or streams of extremely low
velocity are Parachironomus alatus, P. pectinatellae, P. directs, P.
monochromus, P. hirtalatus, P. sublettei, and Harnischia boydi. In
addition P. sublettei and H. boydi larvae occur most frequently in the
canals of southeastern Florida, a fact of, perhaps, greater significance
in zoogeography than in their ecology. Parachironomus carinatus, P.
schneideri, Harnischia viridulus, H. edwardsi, and H. galeator are
ubiquitous. Of all the species of this group thus far known from Flor-
ida Parachironomus alatus is probably the most restricted ecologi-
cally, the larvae being found only in sphagnum bogs and in dense
vegetation in other highly acid waters.

ZOOGEOGRAPHY
A brief review of the literature on chironomids in the United
States shows that in only a few widely scattered areas has any sig-
nificant study of local chironomid faunas been made. Thus the group's
zoogeography can be discussed only in general terms.
Three local species Parachironomus monochromus, Hamischia
edwardsi, and H. viridulus are holarctic in distribution. Species of
nearctic distribution are Parachironomus carinatus, Harnischia gale-
ator, H. collator, Paracladopelma undine, and Cryptotendipes casu-
arius. Species thus far confined to the extreme southeastern United
States are Parachironomus pectinatellae (Alabama and Florida) and
P. directs (Louisiana, Alabama, and Florida). There is a strong pos-
sibility that Parachironomus sublettei and Harnischia boydi may be
neotropical in distribution (see footnote 6). At the present stage of
our knowledge the following four species seem to be endemic to
Florida: Parachironomus alatus, P. schneiderei, P. hirtalatus, and
Paracladopelma loganae.
Our extensive larval collections contain representatives of many
species that have not yet been reared. Thus the present discussion of
the Harnischia group is necessarily incomplete.

Contributions to the BULLETIN oF THE FLOIDA 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 aULLETrm 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
numbers 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 BULLTrr
Florida State Museum
Seagle Building
Gainesville. Florida
