REMARKS .— Spicomacrurus was originally treated as a subgenus of Hymenogadus , but Iwamoto et al. (2011) elevated the subgenus to full generic status. Although obviously related to members of the genera Hymenocephalus and Hymenogadus , the four species of Spicomacrurus are readily differentiated from them by the broad horizontal plates of their nasal bones, elongated posterior lens of the light organ, netlike gular covering, and membranous flange of the outer pelvic fin ray. Spicomacrurus kuronumai is the only member of the genus found in Taiwan .
