Water Bug Updates

(last update 8-xii-2020)


The subgenus Benacus of Lethocerus has been reinstated as a full genus.  See: Perez Goodwyn, P.J. 2006. Taxonomic revision of the subfamily Lethocerinae Lauck & Menke (Heteroptera: Belostomatidae). Stuttgarter Beitr. Naturk. 695: 1-71.  Thus, our largest belostomatid is now called Benacus griseus (Say).



Sigara virginiensis Hungerford from unnamed small creek N of Lake Iamonia (Leon Co.) is new for Florida.

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.

Thanks to Donald Ray and Rick Abad, we have two new Florida corixid records:

Hesperocorixa obliqua (Hungerford) (Escambia Co., Pine Barren Creek)

This species was not covered in my 2006 manual. It will key to couplet 8 (p. 3.12); it can be separated by the more apically produced male pala and the different genitalia (see below)

Sigara mississippiensis Hungerford (Escambia Co., Pine Barren Creek)


Trichocorixa macroceps (Kirkaldy) has been collected in the Florida Panhandle (Manning Creek, Santa Rosa Co.).
