Chaunacops Garman, 1899, is shown to be a senior synonym of the chaunacid anglerfish genus Bathychaunax Caruso, 1989. While Chaunacops has not been used as valid since its erection in 1899, conditions do not exist to allow “reversal of precedence,” as provided by Article 23.9.1. of the International Code of Zoological Nomenclature. Thus, Chaunacops, type species Chaunax coloratus Garman by monotypy, must be regarded as valid and Bathychaunax set aside as a junior synonym.
