AOa photophore series strongly arched (Only species of Hygophum with AOa photophore series strongly arched); PO5 raised above pelvic-fin base; 2 Pol between lateral line and anal-fin base, Pol1 over or behind last AOa (VLO more than 2 photophore diameters below lateral line); 2 Prc on caudal peduncle. Males with single supracaudal luminous organ; females with 2(1-3) coalesced infracaudal luminous organs, sometimes separate.
