Genitalia: female, ultimate ventral segment nearly four times wider than long, posterior margin slightly emarginate with a short broad medium tooth; male valve broad, short; plates broad at base, concavely, attenuately pointed, two and one-half times longer than valve, equalling the pygofers, which are thickly beset with stout hairs.
Described from two females and two males from Holly., Colo. The small size and the black spot near the anal angle of the elytra at once distinguish this species.
