Remarks

The Illinois Natural History Survey website, citing several articles from the primary literature on this genus, indicates that we can assume Hydrocanthus in the northeast (roughly from Maryland north, and east of the Appalachians) to be H. iricolor until proven otherwise. The distributions (north of Mexico) of each species as given there:

H. iricolor - Eastern North America from Maine and Ontario to Michigan, northern Indiana, and south to South Carolina and Georgia

H. atripennis - southern Canada west of the Appalachians ... north to southern Illinois and southern Indiana; rare eastward in Florida ... north to the Carolinas

H. oblongus - Gulf and Atlantic coastal plains from Texas to the Carolinas

H. regius - Florida and Georgia

H. debilis - Texas
