A genus of Opisotretidae with 19 (♂) or 20 (♀) body segments. ♂ vertex with or without modifications. Metaterga with 2 or 3 regular, transverse rows of bacilliform setae. Frontolateral margin of midbody paraterga devoid of shoulders. Ozopore lying close to caudal margin of paratergite’s caudolateral corner.

Gonopod telopodite slender, unipartite, slightly hollow on caudal face only distally; basal frontoventral process (p) either present or absent; distal part devoid of ornamentations (spines, bacilli or setae), lobes or prominent processes, at most microdenticulate near both a small accessory seminal chamber and a hairy pulvillus (Figs 2B, 3).

Type species: Corypholophus minutus Attems, 1938, by original designation.
