Synonymy

Type of genus

Cryptocarenus diadematus Eggers, 1937 .

Diagnosis

Cryptocarenus can be diagnosed from other Scolytinae by the combination of a broadly emarginated eye, metatibiae with spines only on the distal end (as in Hypothenemus ), and an oblique groove instead of a spine or callus below the base of the elytra, and by the dwarfed, flightless males.
