Subgenus Cyrtonychochaeta SCHEERPELTZ 1947
Cyrtonychochaeta was originally described as a genus by SCHEERPELTZ (1947) to include only the type species, C. hoelzeli, which was described in the same paper. Cyrtonychochaeta was subsequently attributed to Oxypoda as a subgenus by ZERCHE (1995), according to whom the genus comprises two species.
