Identification
Helops discipulus can be distinguished from ground beetles (Carabidae) by its bead-like segments (segments wider than long, resembling a keychain clasp) versus the filament-like antennae of carabids. The are concealed beneath the rather than exposed and forward-directed. Like other Helops , it likely moves slowly or only runs rapidly when prodded, rather than the rapid, continuous running typical of ground beetles.
Distribution
North America (based on distribution and Casey 1891 description).
