pp. 8.65-8.67. Two
species have been removed from Einfeldia and
placed in the genus Benthalia. We now have B.
brunneipennis (Johannsen) and B. natchitocheae
(Sublette).

pp. 8.60, 8.64. Dicrotendipes sp. A
has been described as
Dicrotendipes hulberti. See:
Epler, J.H. 2016. A new species of
Dicrotendipes
(Diptera: Chironomidae) from Florida. Zootaxa 4208: 77-83

pp. 8.12, 8.125.
Although I posted information way back in 2006
concerning the occurrence in Florida of Polypedilum nubifer,
I failed to post any notes about how it would key in my
2001 manual. This species, the sole member of the
subgenus P. (Tripedilum), is relatively new to
the US. It has a typical Polypedilum
mentum but has antennae with Lauterborn organs at the
apices of segments 2 and 3. It will not key past
couplet 27 (p. 8.12) in the generic key for Chironominae
because of its oddball antennae. If couplet
27’ is changed to: “ Antennae with 4-7 segments; if with
6 segments, then without alternate Lauterborn organs
apically on segments 2 and 3; if with 5 segments,
Lauterborn organs usually present at apex of segment 2,
but may be present at apex of segment 2 and segment
3”, the species will key to Polypedilum.
Note I had posted information on this matter previously
(5-iv-2008), but I recently found I mixed up some
species and posted incorrect information. I have
removed the previous post.

NEW CHANGES resulting from the
publication of the new Holarctic Keys to larvae, and
how they relate to Florida's midges, can be found here.
16-vi-2015
p.
8.123-124. Although I stated that the larvae of
Phaenopsectra flavipes and
Ph. punctipes were "inseparable", the
two species can be separated as larvae. The larva of
Ph. punctipes
(Wiedemann)(not illustrated in my 2001 manual, figures on p.
8.123 are of
Ph. flavipes)
has a very deep, rounded notch (diastema) on the mandible, the
mentum is steeply descending laterally, the 3 plates of the
pecten epipharyngis are densely adorned with numerous small
teeth (appears spiny like a hedgehog) and there usually is
a strong, well defined line between the frons ("frontal
apotome") and weak sclerite (clypeus) anterior to it. In
Florida
Ph. punctipes
is known from the northern tier of counties. In
Ph. flavipes the diastema
is not deep and rounded, the mentum does not steeply descend
laterally, the 3 plates of the pecten epipharyngis bear large
teeth and the line between the frons and the clypeal sclerite
anterior to it is weakly delimited or almost non-existent (see
figures on p. 8.123). This information was added over a
year ago to the "New Taxa Added" page for the Florida checklist,
but I somehow managed to not include it here.
11-xii-2012
p. 7.47, 7.49. In a recent
paper (Fu, Y & O.A
Sæther. 2012. Corynoneura Winnertz and
Thienemanniella
Kieffer from the Nearctic Region (Diptera: Chironomidae:
Orthocladiinae). Zootaxa 3536: 1-61),
Corynoneura floridaensis Fu &
Sæther was described. This replaces my C. sp. B.
8-xi-2012
p. 8.146. "Stempellina sp. C" is
Neostempellina
reissi. This
was changed some time ago on the Florida checklist but I
negelected to mention it here!!
21-xii-2011
p. 8.98. Tanytarsus
sp. W is Paratanytarsus longistilus; this
taxon was originally based on a specimen with a split
premandible, making it appear 3-toothed. Thus, there
is NO Tanytarsus sp. W!
2-ii-2011
p. 8.98. Paratanytarsus longistilus Bolton,
Ekrem, Sublette & Sublette added. Orignally
diagnosed as Micropsectra sp. D in my 2001 manual.
Also note that Stelechomyia
perpulchra is now known as Kribiodorum
perpulchrum.
22-i-2011
p. 7.163. Phytotelmatocladius
delarosai described, replaces
Orthocladiinae genus H. See: Epler,
J.H. 2010.
Phytotelmatocladius,
a
new genus from bromeliads in Florida and Brazil (Diptera:
Chironomidae: Orthocladiinae). Pp. 285-293 in Ferrington, L.C.,
Jr. (ed.) Proceedings of the XV International Symposium on
Chironomidae. Chironomidae Research Group, University of
Minnesota, St. Paul, MN. 385 + vii pp.
18-ii-2010
p. 8.128. Asheum has been re-established as a
genus, with the sole SE US species
A.
beckae
(Sublette). This was done in a brief statement on page 6
of Oyewo, E.A. and O.A
Sæther. 2008. Revision of Polypedilum (Pentapedilum) Kieffer and Ainuyusurika Sasa et
Shirasaki (Diptera: Chironomidae). Zootaxa 1953: 1-145.
8-xii-2009
p. 8.108. Martin
Spies has recently "split"
Parachironomus supparilis
into three species; the species we have here is
P. longistilus. See:
Spies, M. 2008.
Parachironomus
valdiviensis, spec. nov., and other changes to
nomenclature of Neotropical Chironomidae (Insecta, Diptera).
Spixiana 31: 173-175.
21-v-2008
p. 7.80. At a recent (February 2008)
larval workshop I was teaching, biologist Jessica Bevins
(Kentucky Division of Water) brought some specimens of my
Hydrobaenus sp. O. I’ll be damned if that
thing doesn't have a vestigial beard, similar to
Zalutschia!
The beard is quite minuscule, only 4-5 minute setae – and
appears to be visible only with "Nomarski" (DIC) optics. I
did not see this beard when I did the 2001 manual; I had only a
phase contrast scope at that time (rechecking with the phase
contrast failed to resolve this almost invisible beard on most
of the specimens in my collection). Thus, if you have a
microscope with Nomarski optics, my
Hydrobaenus sp. O may key to
Zalutschia!
p. 8.158. Pete
Cranston recently described
Tanytarsus
bromelicola, a species found in bromeliad phytotelmata
(=water held by plants) [reference: Cranston, P.S. 2007. A new
species for a bromeliad phytotelm-dwelling
Tanytarsus (Diptera:
Chironomidae). Ann. Entomol. Soc. Am. 100: 617-622].
Although I collected this taxon in 1980, from
Tillandsia phytotelmata at
Donald MacDonald Park in Indian River Co., I never put it in my
identification manuals.
Tanytarsus
bromelicola will key to couplet 17',
T. sp. J, in the 2001
key. It can be easily separated by the pale median tooth
of the mentum; that of
T.
sp. J is dark.
5-iv-2008
p. 8.2. The second argument of couplet 2'
should read "antennal blade extends past apex of segment 3" [not
"segment 2"]. The figure is correct, but my typing wasn't
... thanks to Doug Strom for pointing this one out.
Also, a new publication has been published that updates the
names of two Florida midges. My
Stempellinella sp.
A has now been described as
Stempellinella
fimbriata Ekrem. My tentative identification of
another Fl species,
S.
cf.
leptocelloides,
has been verified as the real thing, so the "cf." may be deleted
from the name. The paper: Ekrem, T. 2007. A
taxonomic revision of the genus
Stempellinella (Diptera: Chironomidae).
Journal of Natural History 41: 1367-1465.
8-viii-2007
p. 4.56. An additional species of
Monopelopia has been found in the
Everglades by Rick Jacobsen. This is
M. caraguata, described in:
Mendes, H.F., C.B. Marcondes & L.C. de Pinho. 2003. A new
phytotelmatic species of
Monopelopia
Fittkau, 1962 (Insecta: Diptera: Chironomidae: Tanypodinae) from
South Brazil. Zootaxa 262: 1-10.
