Sw. Chordas et Pl. Hudson, A list of Michigan Corixidae (Hemiptera) with four new state records from the Great Lakes of Michigan, ENT NEWS, 110(4), 1999, pp. 246-250
Corisella tarsalis, Sigara lineata, Trichocorixa borealis, and Trichocorixa
kanza were recently identified from Michigan and constitute new state reco
rds. These four species were collected from two of the Great Lakes or their
connecting rivers and increase the number of corixids for Michigan to 47 s
pecies. We newly report the genus Corisella for Michigan. Although most abu
ndant in the western United States and Canada, scattered Corisella records
in the Midwest (Wisconsin, Ohio and Ontario, Canada) indicated there was a
good probability of its occurrence in Michigan. Finally, we provide an upda
ted list of Michigan Corixidae.
