NEW TAXA ADDED
From time to time, new taxa are
added to the various checklists maintained on this site.
Below is a quick summary of recent additions or
corrections/updates; newest records at top.
(last update 4 March 2026)
Florida Chironomidae
Olecryptotendipes replaces Harnischia complex genus C Epler; because the adult male is yet to be found/described, no species name can be applied. See Orel, O.V. 2022. Additional data on Olecryptotendipes secundus (Zorina, 2003) from Russian Far East, with a description of preimaginal stages (Diptera: Chironomidae). Zootaxa 5205: 87-96.
Stempellina johannseni (Thienemann & Bause) has been found in Florida by Todd Risk (FDEP) at Mill Creek above Jefferson Ave., Escambia County; identified by Broughton Caldwell.
24-x-2024
24-vii-2024
The genus Paracricotopus has been found in Florida. Larvae have been
collected from Mosquito Creek in Gadsden County. Thanks to Mike Heyn
and Todd Risk for reporting this record!
5-viii-2021
Two species have been removed
from Chironomus/Einfeldia and placed in the genus Benthalia. We now have B.
brunneipennis (Johannsen) and B. natchitocheae
(Sublette). This now conforms with what European taxonomists
are doing.
26-iii-2019
Cryptotendipes
rutteri Epler added to replace taxon
previously known as "Cryptotendipes sp. 1 Epler".
See Epler, J.H. 2018. The genus Cryptotendipes Beck et
Beck in Florida, with the description of a new species
(Diptera: Chironomidae: Chironominae). Zootaxa 4433: 583-594.
13-vi-2018
Cryptotendipes pseudotener (Goetghebuer) added to list.
Cryptotendipes casuarius
(Townes) deleted
from list (old Beck & Beck records refer to C. emorsus).
Paper in progress will provide more details later!
24-v-2017
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
16-xii-2016
Paramerina is now considered a subgenus of Zavrelimyia. See: Silva, F.L. da
& Ekrem, T. 2015. Phylogenetic relationships
of nonbiting midges in the subfamily Tanypodinae (Diptera:
Chironomidae) inferred from morphology. Systematic
Entomology. DOI: 10.1111/syen.12141; pp. 1-20.
8-ix-2015
Lipurometriocnemus glabalus Sæther added. This is a new genus and species
for Florida, collected at my house in Wakulla County.
15-xi-2014
Micropsectra sp. F Epler added.
Pontomyia natans Edwards added.
Stempellina cf. subglabripennis (Brundin) added (was S.
sp. D Epler).
Tanytarsus hastatus Sublette & Sasa added (was
T. sp. Epler, T. sp. Q Epler)
T. sp. H Epler and T. sp. I Epler added (duh
... how did I manage to not have these listed before??)
T. sp. alpha Epler, T. sp. beta Epler, T. sp.
delta Epler, T. sp. gamma Epler, T. sp.
epsilon Epler added.
4-vi-2014
Parachironomus sp. D Epler belatedly
added. This taxon will key to couplet 7 in Epler (2001)
but has a smooth outer border to the mentum, has no recurved
striae on the ventromental plate and the anterior border of
the plate is smooth. Todd Risk of FDEP and Bob Rutter
have also found this taxon.
Tanytarsus bromelicola changed to T. cf.
bromelicola
Tanytarsus sp. S changed to T. gibbus.
Have your material verified before you change any names!!
Tanytarsus sp. Y changed to T. messersmithi.
Have your material verified before you change any names!!
Tanytarsus sp. Q deleted (same as T. sp. E)
Tanytarsus sp. Z added based on material from Escambia
County (courtesy of Todd Risk and Mike Heyn, FDEP
Tallahassee).
3-i-2014, updated 4-vi-2014 to
correct error with T. sp. Q
Tanytarsus allicis Sublette added. Status of T.
pelsuei changed to "probable"; Florida specimens
previously identified as this species by J.E. Sublette do not
appear to be T. pelsuei but are apparently an
undescribed species very similar to it and T. dendyi.
28-xii-2013
Status of Tanytarsus sepp
changed from probable to certain; Tanytarsus sp. A
removed because in most cases this is T. sepp. HOWEVER, do not automatically assume
"your" T. sp. A is T. sepp unless you have
associated material. There are other taxa out there
masquerading as T. sp. A; you'll just have to wait
until my new Tanytarsini key for Florida is completed (by
summer of 2014).
22-xii-2013
Added Stempellina sp. D
from Econfina Creek in Panhandle. Somewhat similar to my
S. sp. B (not known from FL), but pedicels for
frontoclypeal setae much longer.
15-vii-2013

Chironomus
Glyptotendipes chelonia (Townes) replaces G. amplus
Townes

Sæther (was my C. sp. B) and Corynoneura capitanea
Fu & Sæther (larva unknown).
6-xi-2012
Belatedly added Polypedilum sp. FL to
Florida checklist. This was called "P. bergi" in
the key, but may not be that species. Associated
material is needed!
10-viii-2012
Labrundinia longipalpus (Goetghebuer) listed as senior
synonym for L. maculata Roback. See Da Silva,
F.L., A.A. Fonseca-Gessner & T. Ekrem. 2011. Revision of Labrundinia
maculata Roback, 1971, a new junior synonym of L.
longipalpis (Goetghebuer, 1921) (Diptera: Chironomidae:
Tanypodinae). Aquatic Insects 33: 293-303.
26-iii-2012
Cladotanytarsus latissimus Giłka and C. subletteorum
Giłka added. Both species are known as adults and pupae only
and are members of the subgenus C. (Lenziella). To
date, both are known only from Florida. See: Giłka, W.
2011. Six unusual Cladotanytarsus Kieffer: towards a
systematics of the genus and resurrection of Lenziella
Kieffer (Diptera: Chironomidae: Tanytarsini). Zootaxa 3100:
1-34. I added these two species to the checklist last
year but I neglected to add them to this page.
26-i-2012
"Stempellina sp. C" is Neostempellina
reissi. This was changed some time ago on
the Florida checklist but I neglected to mention it here!!
21-xii-2011
Pseudosmittia dolobrata Ferrington & Sæther
added. Described from Gadsden County; known only as
adult male. See Ferrington, L.C., Jr. & O.A. Sæther. 2011. A revision
of the genera Pseudosmittia Edwards, 1932, Allocladius
Kieffer, 1913, and Hydrosmittia gen. n. (Diptera:
Chironomidae, Orthocladiinae). Zootaxa 2849: 1-314.
28-xi-2011
Sublettea status in Florida changed from probable to
certain based on specimens from Gadsden Co. Species
level identification uncertain; adults needed! Thanks to
Todd Risk (FDEP) for this record.
3-xi-2011

Thanks to Laura Line (WAR) for sending the specimen for
verification.
28-ix-2011

distinctive larva (not illustrated in my 2001 manual).
Larva has a very deep, rounded notch (diastema) on the
mandible, mentum steeply descending laterally, 3 plates of
pecten epipharyngis densely adorned with numerous small teeth
(appears spiny like a hedgehog) and strong, well defined line
between frontal apotome and sclerite anterior to it. In
Florida known from northern tier of counties.
18-viii-2011
Stilocladius clinopecten Sæther added; known from Wolf Creek,
Walton Co.
22-ii-2011
Tanytarsus sp. W Epler deleted; the "type" was a damaged Paratanytarsus
longistilus!
1-ii-2011
Paratanytarsus longistilus Bolton, Ekrem, Sublette &
Sublette added; known from Duval and Frankin Counties in
FL. Orignally diagnosed as Micropsectra sp. D in
my 2001 manual (see p. 8.98)

7-vii-2004
Florida water beetles
DYTISCIDAE
Here are changes recently added to the
workshop manual from 6-8 May, 2025; these changes override
many of the changes noted earlier (below):
The taxonomy of the tribe Hygrotini
has been updated. Miller & Bergsten (2016) had reinstated
Coelambus as a full
genus and included Hygrotus berneri Young & Wolfe
and H. nubilus (LeConte) in it. But more recent work
by Villastrigo et al. (2017) has established new genera and
subgenera within the tribe. Thus, in Florida, we now have Clemnius (Clemnius) berneri
(Young & Wolfe), Clemnius (Cyclopius) marginipennis
(Blatchley) and Hygrotus (Leptolambis)
nubilus (Le Conte).
The Cybistrinae have been revised and the sole Florida species
in the genus Megadytes
has been moved to the genus Metaxydytes.
Thus we now have Metaxydytes fraternus (Sharp). See Miller et
al. (2024)
4-iii-2026
28-ii-2020
The species
previously known as Rhantus calidus (Fabricius) is now
placed in the new genus Meridiorhantus.
Thus it is now known as Meridiorhantus
calidus (Fabricius). See Balke, M, Hájek, J
& Hendrich, L. 2017. Generic reclassification of
species formerly included in Rhantus Dejean
(Coleoptera, Dytiscidae, Colymbetinae).
Zootaxa 4258: 91-100.
12-v-2017
Prodaticus has
been reduced to subgeneric status within Hydaticus.
Thus our most common species is now Hydaticus (Prodaticus)
bimarginatus.
10-xi-2016
Coelambus Thomson
has been reinstated as a full genus ( see Miller &
Bergsten. 2016. Diving Beetles of the World). Thus
two species previously placed in Hygrotus are now in Coelambus:
C. berneri (Young
& Wolfe) and C. nubilus
(LeConte). Note also that "nubilus" was
misspelled in the manual.
6-xi-2016
Laccomimus
Toledo & Michat replaces Laccodytes Régimbart. See Toledo,
M. & Michat, M. 2015. Description of Laccomimus
gen. n. and eleven new species from the Neotropical region
(Coleoptera, Dytiscidae, Laccophilinae). Zootaxa 3990:
301-354.
30-vii-2015
Parentheses
removed from author name for Celina
grossula - should be Celina grossula LeConte. I had followed an error in
Young (1979) by placing "LeConte" in parentheses. Because
LeConte originally described the species grossula in
the genus Celina, there are no parentheses around
his name.
20-x-2012
Celina slossonae changed back to its original
spelling - call it Celina slossoni ...
again. Note that even though Mutchler misspelled it as "slossoni"
(which is incorrect; because the species was named for a
woman, it should have been "slossonae"), Article 33.4
of the ICZN states that such a change is to be termed an
"incorrect subsequent spelling".
14-iv-2012
Neoporus floridanus moved to Hydroporus
Uvarus sp. 1 added
28-vi-2010
changed Eretes sticticus (L.) to E.
explicitus Miller, based on my re-examination and
dissection of Young's material
20-i-2010
Ilybius incarinatus Zimmermann added [Wakulla Co.]
29-xi-2009
Prodaticus added,
includes P. bimarginatus and P. rimosus.
The two included species were formerly placed in the
subgenus H. (Guignotites); this is a junior synonym
of Prodaticus, which has been elevated to full genus
status. See: Miller, K.B., Bergsten, J. & M.F. Whiting.
2009. Phylogeny and classification of the tribe Hydaticini
(Coleoptera: Dytiscidae): partition choice for Bayesian
analysis with multiple nuclear and mitochondrial
protein-coding genes. Zoologica Scripta 38: 591-615.
9-vi-2009
added Matus bicarinatus (Say) [Blackwater River and
Escambia River, Santa Rosa Co., leg. Dana Denson & Andy
Rasmussen]
5-iv-2008
added Dytiscus carolinus Aubé [Apalachicola Bluffs and
Ravines Preserve, leg. D. Almquist, Florida Natural Areas
Inventory]
9-v-2007
Hydroporus pseudoniger Nilsson & Fery [nom.
nov. for ruficeps Aubé]
28-xii-2006
added Acilius confusus Bergsten
Derovatellus floridanus Fall
[reinstated as full species]
13-iii-2006
Kamite (2016) had synonymized Promoresia with
Optioservus. Later, Kobayashi et al. (2021) synonymized Gonielmis and Optioservus with Heterlimnius. Thus we now
have three species of Heterlimnius recorded from
Florida: H. dietrichi (Musgrave), H. ovalis (LeConte)
and H.tardellus (Fall).
4-iii-2026
27-xii-2016
added Stenelmis mera Sanderson [Brushy Creek, McDavid
Creek, Pine Barren Creek, Escambia Co., leg. Andy Rasmussen
& Dana Denson]
S. morsei White [Brushy Creek, Escambia Co.
leg. Andy Rasmussen and Dana Denson]
31-v-2008
added Oulimnius nitidulus (LeConte)
14-ii-2006
GYRINIDAE
added
Spanglerogyrus albiventris Folkerts
12-viii-2005
added Gyrinus marginellus Fall
7-vii-2004
HALIPLIDAE
Removed Peltodytes
pedunculatus pending examination of specimen
11-xii-2008
added Peltodytes
pedunculatus to Florida fauna [fide Nilsson & Vondel
2005. World Catalogue of Insects. Vol 7.]
4-xii-2008
HYDRAENIDAE
Two new hydraenids have been
described from Florida (Hydraena chandleri
Perkins and H. lenticula Perkins) and the genus Gymnochthebius
has again been relagted to subgeneric status within Ochthebius.
See: Perkins, P.D. 2023. New Neotropical and Nearctic species
of water beetles in the genera Hydraena Kugelann and Ochthebius
Leach, a key to North American genera and subgenera of the
family, new distribution records, and a synopsis of ecology,
behavior and morphology related to aquatic life. Zootaxa
5367: 1-86.
4-iii-2026
HYDROCHIDAE
The species of Hydrochus have been
reviewed for Mississippi (Worthington, R.J., Hellman, J.L.
& Lago, P.K. 2016. Hydrochidae (Coleoptera) of
Mississippi. Transactions of the American Entomological
Society 142: 167-213. As a result, several of my
letter-designated taxa now have "real" names. H.
sp 1 = H. falsus Hellman; H. sp. 2 = H.
jiawanae Makhan; H. sp. 5 = H. pajnii
Makhan; H. sp. 6 = H. schereri Makhan; H.
sp. 8 = H. jaechi Makhan.
23-xii-2016
HYDROPHILIDAE
Novochares is a new genus for Florida,
based on the probably introduced species formerly known as Helochares sallaei; thus we now have Novochares sallaei
(Sharp, 1882). See Girón
& Short 2023. The Acidocerinae (Coleoptera,
Hydrophilidae): taxonomy, classification, and catalog of
species. Zookeys 1045: 1-236
29-vii-2024
Hydrophilus ensifer recorded from Florida.
See Pintar, M.R. & Keller, J.L. 2020. First record of Hydrophilus
ensifer Brullé (Coleoptera: Hydrophilidae) in the
continental United States. The Coleopterists Bulletin 74:
696-698.
28-xii-2020
Helocombus is now considered to be part of
Cymbiodyta. See Toussaint, E.F.A.
& Short, A.E.Z. 2019. Historical biogeography
of Holarctic Cymbiodyta water scavenger beetles in the
times of Cenozoic land bridge dispersal routes. Insect
Systematics and Diversity 3: 1-7.
13-i-2020
Hydrobius tumidus is now Limnohydrobius tumidus (LeConte). See Short,
A.E.Z., Cole, J. & Toussaint, E.F.A. 2017.
Phylogeny, classification and evolution of the water scavenger
beetle tribe Hydrobiusini inferred from morphology and
molecules (Coleoptera: Hydrophilidae). Systematic Entomology 42:
677-691. Of the other two species of Hydrobius
mentioned on p. 12.42 of my FL water beetle manual, melaenus
(Germar) is also now placed in Limnohydrobius; H.
fuscipes (L.) remains in Hydrobius.
17-x-2017
Anacaena suturalis (LeConte) changed to Crenitulus suturalis
(LeConte). For more details, download this addendum.
9-iii-2015
Changed Phaenonotum minor
to P. minus (gender concordance)
6-viii-2009
Changed record for Laccobius
minutoides to L. reflexipenis.
23-vii-2009
added Cercyon crocatus Smetana [I missed the FL record
for this taxon previously]
Laccobius minutoides d'Orchymont [a new genus and
species record for FL; Big Escambia Creek, Escambia Co., leg.
Andy Rasmussen & Dana Denson]
14-viii-2008
The previous (31-v-2008) record
for Cercyon mendax Smetana [Arbuckle Creek, Highlands
Co., leg. Dana & Edie Denson] is incorrect; this record
refers to C. floridanus Horn. The species is
still recorded for Florida in Hansen, M. 1999. World Catalogue
of Insects, Volume 2, Hydrophiloidea (s. str.) (Coleoptera).
Apollo Books, 416 pp.
30-vii-2008
NOTERIDAE
Pronoterus has been synonymized with
Suphisellus. See Baca, S.M, Toussaint,
E.F.A., Miller, K.B. & Short, A.E.Z. 2017.
Molecular phylogeny of the aquatic beetle family Noteridae
(Coleoptera: Adephaga) with an emphasis on data partitioning
strategies. Molecular Phylogenetics and Evolution 107:
282-292. Thus our single species of this
former genus is now Suphisellus semipunctatus
(LeConte).
10-iii-2017
SCIRTIDAE
Prionocyphon limbatus LeConte added to Florida list.
26-vii-2018
All species of Cyphon from Florida are now placed in Contacyphon (with the exception of "Cyphon"
sp. 3 Epler, which represents a new genus, currently being
described). See Zwick, P., Klausnitzer, B. & Ruta, R.
2013. Contacyphon Gozis, 1886 removed from
synonymy (Coleoptera: Scirtidae) to accomodate species so far
combined with the invalid name, Cyphon Paykull,
1799. Entomologische Blätter und Coleoptera 109:
337-353. Note also that species from the "Cyphon
collaris complex" (none known to date from Florida) are
now placed in the genus Nyholmia. See
Klausnitzer, B. 2013. Monophyletische Artengruppe der
ehemaligen Gattung Cyphon Paykull, 1799 und
Beschreibung von neuen Gattungen (Coleoptera,
Scirtidae). Entomologische Nachrichten und Berichte 57:
255-262.
8-i-2014
Ora discoidea Champion added to Florida list.
28-xii-2012
corrected
species list in regards to Cyphon
padi, which is NOT Nearctic; record from Peck
& Thomas (1998) for C. padi (L.) probably refers
to C. neopadi
Klausnitzer, 1976.
9-xi-2012
replaced
Scirtes sp. 1
with Scirtes goliai
Epler
30-x-2012
