Front coxal cavities externally closed, internally open. Pronotum elongate. Prepectus absent. Middle coxal cavities open. Elytra: long hairs absent. Epipleuron moderate. Elytral interlocking mechanism present, carinae reduced. Elytral punctation regular, scales absent. Wing: radial cell open (outer vein present), wedge cell absent, cross vein MP3-4 absent, cross vein AA1+2-3+4 absent. Front tibiae: spines along side large. Hooked spur present.

Biology
Predatory. North American species have been both reared and collected from various species of pine and willow, also from Rhus, Pseudotsuga, and other trees (Barron 1971[1], Dajoz 1997[3]). The Corticotomus species were mostly found under bark but also in the burrows of Cryphalus (Scolytinae) (Barron 1971[1]). Dajoz (1997)[3] noted Corticotomus apicalis associated with the bark beetle Chaetophloeus parkinsoniae. The way of life of Corticotomus is probably similar to that of Nemozoma.
Distribution
Distributed from Brazil to Canada. One species, unknown to me, is described from Chile.
