Character: D. 13 (12); A. 19 (18); P. 15 (14); GR 6-7 +1 + 14-15, total 21-23; AO 6 (5-7) + 4 (3-5), total 11 (10-12) Opercular margin sharply angular posterodorsally, abruptly produced into a tapering projection posteriorly. Origin of dorsal fin behind vertical through base of outermost ray of ventral fin. Origin of anal fin under base of penultimate ray of dorsal fin. Base of adipose fin well in advance of vertical through end of base of anal fin. Pectoral fin long, extending to about second AOa, with upper end of its base about on level of ventral margin of orbit. Ventral fin short, not reaching anus. A very small Dn immediately posterodorsad to nasal apparatus. Op1 well developed, opposite middle of expanded portion of maxilla; Op2 somewhat behind vertical through posterior margin of Op1 and about on level of ventral margin of orbit. PLO well in advance of upper end of base of pectoral fin, partly or completely covered by operculum and 2-3 times its own diameter below lateral line. PO1 through PO4 gently arched; PO5 abruptly displaced dorsalaterally to a position in front of base of outermost ray of ventral fin. VLO distinctly nearer to lateral line than to base of ventral fin, its distance from latter 2-2.5 times as great as that between it and lateral line. SAO series widely angular; SAO1 slightly behind vertical through center of VO3, well below line connecting VLO with SAO2 and on or very slightly above line connecting VO2 with SAO2; second SAO about over origin of anal fin; SAO3 over AOa1-AOa2 interspace, in contact with lateral line. AOa1 slightly depressed, space between it and AOa2 usually a little wider than spaces between rest of organs of same series. AOp level and equidistant; AOp1 over or somewhat in advance of end of base of anal fin. Pol slightly behind vertical through center of last AOp and in contact with lateral line. Prc widely separated; Prc2 about its own diameter below level of lateral line. 
Habitat: Benthopelagic and mesopelagic in slope and oceanic waters, but usually not high-oceanic. Occurs in the upper 200 m at night. Occasionally seen during dark nights on slopes that are near very deep water. Attracted by light like moths, becoming disoriented  
Distribution: Off eastern and southern Taiwan; Indian Ocean: 18°N-20°S, to 42°S in the Agulhas Current. Pacific Ocean: 21°N-10°S. 
Name Code: 381190
