Regional Records: Ptychognathus crassimanus Finnegan, 1931: 649 (Marquesas). - Poupin, 1996a: 69, 77, 78 (Checklist). - Remark: It seems that this species was never recorded after its description. In particular, it does not appear in the works by Marquet (1988, 1991, 1993), who has only collected Ptychognathus easteranus (det. Holhtuis), in the Marquesas rivers.
