中國動物誌-燈籠魚目(陳等, 2002)
Character: D. 13; A.19; P.14; AO 9+5, total 14; G.R. 5+1+14, total 20. Mouth oblique; maxillary expanded posteriorly. Eye very large. Upper posterior opercular margin acute, non-serrate. Origin of dorsal fin over base of ventral fin. Origin of anal fin behind end of base of dorsal fin. Pectoral fins extending behind VLO. Ventral fins almot reaching VO4. Base of adipose fin in advance of end of base of anal fin. Scales cycloid, those of lateral line enlarged. Dn and Vn present. Op1 close behind posterior end of premaxillary; Op2 close level of ventral margin of orbit. PLO about its diameter anterodorsad to upper end of base of pectoral fin. PVO1 behind PO2; PVO2 at lower end of base of pectoral fin and over, or slightly in front of PO3. Five PO, PO3-PO4 interspace shortest; PO5 somewhat displaced dorsalaterally. VLO behind base of ventral fin and midway between if and lateral line; SAO and VO4 almost on a straight line; SAO2 nearer to SAO1 than to SAO3 which is somewhat behind vertical through origin of anal fin and immediately below lateral line. AOa almost forming a straight line. Pol directly over last AOa, on vertical through anterior end of base of adipose fin and immediately below lateral line. First AOp over end of base of anal fin. Prc2 higher than Prc1 but still nearer to bases of ventral porcurrent caudal rays than to lateral line; the two organs are about one photophores diameter apart from each other. Male has 5 to 8(3-6) luminous scales in SUGL, and females with 2-6 small, round to oblong luminous scales in INGL. 
Habitat: High-oceanic, nyctoepipelagic at the surface and to 950 m and generally found between 475-850 m during the day. Oviparous, with planktonic eggs and larvae (Ref. 31442). Females reach sexual maturity at 4,8 cm, males at 3,5 cm.
