Identification
Members of Elaphropus are small ground beetles, usually under 5 mm in length, with characteristic pronotal and elytral sculpturing. E. incurvus can be distinguished from by the specific curvature suggested by its name ('incurvus' = curved/bent), likely referring to features of the male genitalia or body outline. Precise identification requires examination of genitalic structures and comparison with . The species may be confused with other small Elaphropus in eastern North America, particularly E. xanthopus and E. granarius.
