Hsuan-Ching Ho, Hiromitsu Endo, and Kazunobu Sakamaki (2008) Halicmetus nigra sp. nov. is described on the basis of 32 specimens collected from the western Pacific off Japan, Taiwan, and Australia at depths of 280-1000 m.  The new species differs from its congeners in the body surface being uniform gray to black; the rostrum extending anteriorly, slightly overhanging the mouth; a black band on each fin or fins entirely black; and in differences of morphometrics and squamation.  Two species also recognized from the western Pacific are H. reticulatus and H. cf. ruber.  Morphological data for nominal species in Halicmetus are provided for comparison with the new species.

Key words: Ogcocephalidae, Batfish, Taxonomy, New species, Halicmetus nigra.
