Taiwan voucher material: (1 specimen) NMMB-P 6424, Taichong, 16 Dec 1962. Remarks: A very common species at fish markets, especially in Keelung in May 1988 ( DAE, pers. obs.), but not a particularly common species in fisheries landings in Taiwanese waters in recent years. Paragaleus acutiventralis Chu, 1960 , described from off Bei-Hai in China, is a junior synonym of this species. Similar to Chaenogaleus macrostoma but differs in dentition and in having strongly falcate fins (vs. not falcate). Historically probably confused with C. macrostoma and records of Negogaleus balfouri and N. macrostoma may actually refer to this species. Appears to be naturally low in abundance where it occurs and possibly rare in Taiwanese waters presently.

Conservation status: Vulnerable.
