    Ctenobium LeConte, 1865 (Coleoptera: Ptinidae) was described for a single species, Ctenobium antennatum LeConte, 1865 (Fig. 1). Ctenobium most closely resembles Oligomerus Redtenbacher, from which it can be readily separated—the pro-coxae in Ctenobium are distinctly separated by a parallel-sided prosternal process, and the antennae are clubbed with antennal segments 3–8 serrate to pectinate (Figs. 1–2) (Philips 2002; White 1971). The conical shape and granulate surface of the last visible abdominal segment are also characteristic for Ctenobium (Fall 1905; LeConte 1865).
