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 October 2021)

Florida Chironomidae

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!

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.

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.

Cryptotendipes pseudotener (Goetghebuer) added to listCryptotendipes casuarius (Townes) deleted from list (old Beck & Beck records refer to C. emorsus).  Paper in progress will provide more details later!

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

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.

Lipurometriocnemus glabalus Sæther added.  This is a new genus and species for Florida, collected at my house in Wakulla County.

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.


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.

Status of Tanytarsus sepp changed from probable to certain; Tanytarsus sp. A removed because in most cases this is T. seppHOWEVER, 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).

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.

Updated taxonomy of Cryptochironomus stylifera (Johannsen), previously confused with C. psittacinus (Meigen) by Townes

Bethbilbeckia floridensis to Macropelopia
Cantopelopia gesta to Monopelopia
Hayesomyia senata to Thienemannimyia
both Helopelopia species to Conchapelopia
Asheum beckae back to Polypedilum
Einfeldia brunneipennis
and E. natchitocheae to Chironomus

Glyptotendipes chelonia
(Townes) replaces G. amplus Townes


Removed Orthocladiinae genus E; this is most likely a Metriocnemus.

Added Corynoneura floridaensis Fu & Sæther (was my C. sp. B) and Corynoneura capitanea Fu & Sæther (larva unknown).

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!

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.

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.

"Stempellina sp. C" is Neostempellina reissi.  This was changed some time ago on the Florida checklist but I neglected to mention it here!!

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.

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.

Saetheria sp. 1 added (Leon Co.: Panther Creek).  Thanks to Laura Line (WAR) for sending the specimen for verification.

Phaenopsectra punctipes (Wiedemann) added, based on the 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.

Stilocladius clinopecten Sæther added; known from Wolf Creek, Walton Co.

Tanytarsus sp. W Epler deleted; the "type" was a damaged Paratanytarsus longistilus!

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)

Polypedilum ontario (Walley) confirmed from Florida: Okaloosa Co., Turtle Creek; fide Todd Risk, FDEP

Tvetenia tshernovskii (Pankratova) added to replace T. vitracies Sæther

Kribiodorum perpulchrum added to replace Stelechomyia perpulchra

Phytotelmatocladius delarosai Epler added to replace Orthocladiinae genus H

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.

Chironomus columbiensis Wülker, Sublette, Morath & Martin belatedly added

Zavrelia aristata Ekrem & Stur added

Parachironomus longistilus Paggi  - Martin Spies has recently "split" P. 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.

Florida water beetles

The species previously known as Uvarus sp. 1 Epler has been described as Uvarus sinofelihelianthus Epler. See Epler, J.H. 2020.   A new species of Uvarus Guignot, 1939 (Coleoptera: Dytiscidae: Hydroporinae: Bidessini) from Florida, USA. Insecta Mundi 0752: 1-4.

   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.

   Prodaticus has been reduced to subgeneric status within Hydaticus.  Thus our most common species is now Hydaticus (Prodaticus) bimarginatus.

   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 CoelambusC. berneri (Young & Wolfe) and C. nubilus (LeConte)Note also that "nubilus" was misspelled in the manual.

     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.

     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.

    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". 

    Neoporus floridanus moved to Hydroporus
    Uvarus sp. 1 added

    changed Eretes sticticus (L.) to E. explicitus Miller, based on my re-examination and dissection of Young's material

    Ilybius incarinatus Zimmermann added [Wakulla Co.]

    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.

added    Matus bicarinatus (Say) [Blackwater River and Escambia River, Santa Rosa Co., leg. Dana Denson & Andy Rasmussen]

added    Dytiscus carolinus Aubé [Apalachicola Bluffs and Ravines Preserve, leg. D. Almquist, Florida Natural Areas Inventory]

    Hydroporus pseudoniger  Nilsson & Fery [nom. nov. for ruficeps Aubé]

 added   Acilius confusus Bergsten
Derovatellus floridanus Fall [reinstated as full species]


Promoresia has been synonymized with Optioservus. Thus we now have two species of Optioservus recorded from Florida: O. ovalis (LeConte) and O. tardellus (Fall).  See Kamite, Y.  2016.  Revision of the genus Optioservus Sanderson, 1953, part 3: The O. elegans species group.  Koleopterologische Rundschau 86: 205-212.

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]

added  Oulimnius nitidulus (LeConte)


added   Spanglerogyrus albiventris Folkerts

added    Gyrinus marginellus Fall

   Removed Peltodytes pedunculatus pending examination of specimen
    added Peltodytes pedunculatus to Florida fauna [fide Nilsson & Vondel 2005. World Catalogue of Insects. Vol 7.]

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.


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 & Sharp 2021. The Acidocerinae (Coleoptera, Hydrophilidae): taxonomy, classification, and catalog of species. Zookeys 1045: 1-236

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.

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.

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

Anacaena suturalis (LeConte) changed to Crenitulus suturalis (LeConte).  For more details, download this addendum.

Changed Phaenonotum minor to P. minus (gender concordance)

Changed record for Laccobius minutoides to L. reflexipenis.

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]

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.


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).


Prionocyphon limbatus LeConte added to Florida list.

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.

Ora discoidea Champion added to Florida list.

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.

replaced Scirtes sp. 1 with Scirtes goliai Epler

added Scirtes oblongus Guérin-Méneville [new species for Florida, USA and Nearctic]. Removed Scirtes sp. 2

added Cyphon spp. 3, 4, 5.  Added Sarabandus robustus to Florida fauna [Paynes Prairie, Gainesville]. Changed Elodes pulchella to Sacodes pulchella.

added Sacodes thoracica (Guérin-Méneville) as a taxon that might occur in Florida

Florida water bugs



Sigara virginiensis Hungerford [unnamed small creek N of Lake Iamonia, Leon Co.]

The genera Micronecta and Synaptonecta have been placed in their own family, Micronectidae.  See Epler, J.H. & Denson, D.R.  2017. New records of Corixidae and Micronectidae (Insecta: Heteroptera: Corixoidea) from Florida, with a checklist of all species known from the state.  Entomological News 126: 410-414.

added  Hesperocorixa obliqua (Hungerford) [Pine Barren Creek, Escambia Co.]
Sigara mississippiensis Hungerford [Pine Barren Creek, Escambia Co.]

Trichocorixa macroceps (Kirkaldy) [Manning Creek, Santa Rosa Co.]


Ochterus americanus (Uhler) added, based on male specimen collected from Sweetwater Creek in Liberty County
