Length: 13 - 27 mm in the genus
In genus Dicaelus the elytral striae are modestly curved, paralleling the sides of the elytra, and they converge at the apex. There is a depressed area at the base of the pronotum. Typically the antennae are dark at the bases and lighter toward the apices. Males have the front tarsal segments 1-3 widely expanded (Ciegler, 2000).
Members of this genus are most often encountered under logs. They may also be under bark, in leaf litter, or may be attracted to lights.
