ABSTRACT: Onenewgenusandfivenewspeciesofcorixidshaverecentlybeenrecordedfrom
Ohioaspartofacomprehensivesurveyofadultaquaticinsects.Thetotalnumberofcorixidtaxa
now known from Ohio is 25. All five taxa were collected using black light traps. The newly
reportedgenus,Corisella,isknownmainlyfromwesternNorthAmerica.Corisellainscriptahas
heretoforeonlybeenfoundwestoftheMississippiRiver.Theotherfournewspeciesrecordsfor
Ohio represent three genera and include Palmacorixa buenoi, Sigara dejecta, S. hubbelli, and
Trichocorixa kanza. All five new taxa were collected on one or more of the following State
WildlifeAreas: BigIsland, KilldeerPlains,andResthaven.
There are almost 80 State Wildlife Areas in Ohio. These are managed by
the Ohio Division ofWildlife (the Division) for a variety ofhunting, fishing,
recreational,and watchable wildlife functions. However,fewofthese wildlife
areashave been surveyedfortheiraquatic insectfauna. Recently the Division
funded the Ohio Biological Survey (the Survey) toconduct athree yearstudy
ofthe state-listed, special category species for Killdeer Plains WildlifeArea.
The Survey is alsoconducting amulti-yearcomprehensive survey oftheadult
aquatic insects in Ohio co-funded by the Division, the Partnerships forWild-
life Foundation of the U.S. Fish and Wildlife Service, and the Procter and
Gamble Co., Inc. Finally, the Wisconsin Department of Natural Resources,
withfundingfrom PartnershipsforWildlife,hascontracted withthe Survey to
conduct a six-state prairie Lepidoptera study. All of these projects generated
aquaticinsectcollectionsfromstatewildlifeareas,especiallyBigIsland(Marion
County), KilldeerPlains (Wyandot County), and Resthaven (Erie County).
TheaquatichemipteranfaunawithinOhio,includingthefamilyCorixidae,
is poorly known. There have been no previous studies pertaining specifically
to the aquatic members ofthis order in Ohio. This void is evident whencom-
prehensive aquatic Hemiptera works, such as Truxal's (1953) revision ofthe
genusBuenoa (Hemiptera; Notonectidae), contained noOhio material. How-
ever, efforts such as that ofWilliams et al. (1996), Chordas (in review), this
paper, and the current survey ofadult aquatic insects in Ohio, are addressing
this deficiency. Until recently, only 20 species of the family Corixidae (In-
secta: Hemiptera) were known from Ohio. These included the genera (# spe-
cies): Hesperocorixa (9); Palmacorixa (3); Rhamphocorixa (1); Sigara (5);
and, Trichocorixa (2). In contrast, there have been 49 species, representing 9
genera, ofwaterboatmen reported from Wisconsin (Hilsenhoff, 1984).

ingonenewgenusandfivenew species.This isoneofaseriesofpapersabout

las foraquatic Hemiptera in Ohio.
METHODS
AdultcorixidswerecollectedfromMaythroughOctoberusingblacklight
traps. SpecimensfromKilldeerPlainsandResthavenWildlifeAreaswerecol-
lected during a survey ofprairie moths. Specimens from Big Island Wildlife
Area were collected during a study of aquatic insect dispersal to proposed
reconstructedwetlandareas.Identificationsweremadeusingkeysanddescrip-
tionsinHungerford(1948)andSailer(1948).Polhemusetal. (1988)wasused
as the reference forknown distributional records. Specimens are preserved in
75% ethanol and deposited in the Ohio Biological Survey's Aquatic Insect
Collection.
RESULTS
All species collected on Big Island, KilldeerPlains, and Resthaven Wild-
life Areas are presented in Table 1. The new genus and species records for
Ohio are indicated by symbols. Additional county records from sites outside
ofthe three wildlife areas are provided in table footnotes.

DISCUSSION
Thefivenew staterecords increasethe total statelistofcorixidsby 25%to
25 species. This relatively large increase in the faunal list, from a small num-
berofsites, supports the notion that Ohio is undercollected. Given the distri-
butionspublishedbyPolhemusetal.(1988),approximately 1 additionaltaxa,
primarily in the genus Sigara, could possibly be found in Ohio. Furthermore,
Chordas(inreview)specificallydiscussespotentiallyresidentspeciesbelong-
ingtothe genusHesperocorixathatmay ultimately be found inOhio.TheTill
PlainsphysiographicprovinceinwesternOhiocontainsremnantsofmidwestem
prairies which once were common. Killdeer Plains and Big Island Wildlife
Areas contain some of these relict areas. Additional collecting in these and
othersimilarareascouldreveal othertaxawhose distribution isnormallycon-
sidered more typical ofthe prairie states west of the Mississippi River. Ohio
has portions of four other physiographic provinces (Lake Plains, Bluegrass,
GlaciatedAllegheny Plateau, and UnglaciatedAllegheny Plateau) which also
could contain taxa typical to these regions in other states but heretofore not
collected or identified from Ohio.
Sigara defecta: Ohio lies along the very southern edge of this species'
midwesternrange (Hungerford, 1948;Polhemusetal., 1988).This specieshas
beenpreviously reported only from two states bordering Ohio (Michigan and
Pennsylvania). However, its occurrence in two widely spaced wildlife areas
suggests that it is likely tobe found in additional Ohio locations.
Sigara hubbelli: This species has previously been reported for all of the
states bordering Ohio (Indiana, Kentucky, Pennsylvania, and West Virginia)
except Michigan to the north. Based on the distributional data presented by
both Hungerford (1948) and Polhemus et al. (1988), Ohio lies well within its
A
known range and it is no surprise that it has been found within the State.

County. Although the single male specimen was taken by black light sam-
pling,several specimenstakenbydipnetsampling,fromtwoadditional locali-
tieswithinOhio (Table 1), are inthe firstauthor's private collection. This fur-
ther serves toestablish the presence ofthis species within Ohio.
Trichocorixa kanza: The report ofthis species in Ohio extends the north-
em distribution of this primarily southern species. Of the five new species
reportedfromOhio,this species wastaken inthelargestnumbersandwasone
ofthe least anticipated. It has been taken from only one state, Pennsylvania,
bordering Ohio. In addition to its historical distribution in the southeastern
United States (Polhemus et al., 1988), the northern records ofthis species in-
clude the DistrictofColumbia, Delaware, Maryland, Pennsylvania, and Wis-
consin (Hilsenhoff, 1984; Polhemus etal, 1988).
Palmacorixabuenoi:Thisspecieshaspreviouslybeenreportedforall states
bordering Ohio (Indiana, Michigan, Pennsylvania, and West Virginia), except
342 ENTOMOLOGICALNEWS
Kentucky tothe south. Itsreporteddistributionextends from Ontario south to
Florida and west to Iowa (Polhemus et al., 1988). This vast distribution, and
records forbordering states, clearly place Ohio within its range.
Corisella inscripta: Historical records for the genus Corisella are prima-
rily from western NorthAmerica(Hungerford, 1948). Twospecies ofthis ge-
nus have been recorded from states east of the Mississippi River: Corisella
edulis (Champion), 1901 and Corisella tarsalis (Fieber), 1851 (Hilsenhoff,
1984; Hungerford, 1948; Polhemus et al., 1988). Priorto this paper, the east-
ernmost records of Corisella inscripta were from Missouri (Polhemus et al.,
1988) and a single male specimen fromArkansas (Cochran and Harp, 1990).
Corisella inscripta represents not only a new genus forOhio, but also a con-
siderable eastern geographical range extension.
