Diagnosis: dorsal finrays 8-9, anal finrays 20-25, pectoral finrays 25-28, shorter than pelvic fin. Scales in lateral line 55-59. Luminous organs present on isthmus (IO), within the pelvic fin musculature (POa), just posterior to the pelvic fin bases (POp) and just anterior to the anus (A). Colour: in alcohol, uniformly dull brown, slightly darker on the edges of scale pockets; a dense black stripe along belly between POp and AO luminous organs; pigment present on all fins. Size: to 138 mm SL.

Habitat: oceanic, meso- or bathypelagic. Some night-time records of adults are from the upper 200 m, but most are from hauls to depths considerably in excess of 500 m; larvae taken in all parts of the range all times of the year, most commonly in hauls to depths between 300 and 600 m. Food: adults prey on other midwater fishes. Reproduction: no data.

Distribution: widespread in southern oceanic areas northward to 61° 04' N; absent in Mediterranean. Elsewhere, tropical and subtropical regions of all the oceans, but unknown in the eastern Pacific.
