Genus Uroptychus Henderson, 1888

Remarks. Uroptychus is the largest genus in the Chirostyloidea , with more than 250 described species, 100 of these recently described from the Indo-West Pacific by Baba (2018). Just after Baba (2018), Schnabel (2020) described 24 new species from waters around New Zealand, citing a personal communication with Dr. K. Baba that many more undescribed species await description in natural history collections around the world. From waters around Japan, 26 species have been recorded ( Baba et al. 2008; Baba 2018). In this study, one new species is described from the West Mariana Ridge.
