Short Description
Original diagnosis after DIDIER, 2008 [3359]: A species of chimaeroid fish assigned to the genus Hydrolagus on the basis of a ventral caudal fin that that is not indented at its origin to form a separate anal fin. Hydrolagus homonycteris is distinguished from its congeners by the following combination of characters: body colour an even dark black or blackish-brown, dorsalfin spine longer than height of first dorsal fin, pelvic fins distinctly round in shape, and males with pelvic claspers that are dark at the base with pale tips, divided for the distal 1/3 of their length.
