Dorsal-fin rays 14–15; anal-fin rays 16; pectoral-fin rays 13–14; gill rakers 18–21; vertebrae (rarely 33).
Largest specimen less than 50 mm SL. body narrow, tapering into narrow caudal peduncle; its greatest depth less than length of subcaudal photophore group; eye relatively small, orbital diameter greater than six times into SL; post-temporal spine long, about one-half the diameter of orbit (or greater); dorsal spine short; preopercle spine short, narrowly triangulate; abdominal keel scales smooth, not extending far beyond body margins; subcaudal photophores spaced apart (about width of a photophore between them), distance between subcaudal and anal photophores about the same as length of one of the former; supra-anal raised only slightly above anals, with first supra-anal higher than second; supra-abdominal photophores in an oblique straight line; jaws medium; teeth minute; definite vomerine teeth present; gill rakers long, spinose; in preservative, pigment dark dorsally with broad, dark bar reaching to or near midline; dark pigment spots along trunk midline with pigment striations radiating from them; dark pigment above ventral photophores.
Post-temporal spine simple, bearing no basal spines; lateral edge of post-temporal-supracleithrum smooth; keel scales with smooth ventral surfaces; supraanal photophores separate, usually raised well above anal group. Post-temporal spine long, its length greater than one-fourth the diameter of orbit; anal photophore number 10 to 13 (adults only); body long and narrow, greater than 1.7 times body depth; first supra-anal photophore even with or raised above the second. Gill rakers 18 to 21; supra-anal photophores distinctly raised above the anal group; preopercle spine short, somewhat triangulate. Subcaudal photophores somewhat spread; length of subcaudal group equal or greater than narrowest peduncle depth; distance from top of last supra-anal photophore to top of first anal less than one-half preanal length.
Extremely disjunct range; from a specimen north of Madagascar in the Indian Ocean and from a single capture in the Central Pacific north of the Marquesas Islands.
