Identification
Seperation of the genera of Corticariinae by dorsal and external characters only is problematic.
Most species of this genus have a prebasal, almost round pit on the pronotum, as in Corticaria, and male protibia bear a subapical spine. Elytra rather short, well rounded at sides (also applies to Melanophthalma).
Conclusively seperated from similar genera by strongly asymmetrical male genitalia.
Range
Across the continent(1)
