Redlist Status NL Not in IUCN Redlist     
Characteristic A very slender-bodied lanternshark. Head width about equal to preoral snout. Prespiracular length slightly greater than distance from spiracles to pectoral origins; gill openings very short, about as wide as spiracle, 1/3 eye length or less; bladelike unicuspidate teeth in lower jaw and teeth with cusps and cusplets in upper jaw. Distance from snout tip to first dorsal spine about equal to distance from first dorsal spine to second dorsal insertion, first dorsal base considerably closer to pectoral bases than pelvics. Two spined dorsal fins. Origin of first dorsal fin above inner margins of pectoral fins. Interdorsal space short, slightly less than distance from snout tip to pectoral origins; second dorsal fin much larger than first and about twice its area; distance between second dorsal base and upper caudal origin about 1.4 in interdorsal space; caudal fin long and slender, length of dorsal caudal margin about equal to distance from snout tip to pectoral origins. No anal fin. Lateral trunk denticles with slender, hooked conical crowns, arranged in prominent regular longitudinal rows on dorsal surface of head, sides of body and tail that give the shark an etched, engraved appearance; snout largely covered with denticles; no rows of greatly enlarged denticles on flanks above pectoral fins. Distal margins of fins largely covered with skin, not fringed with naked ceratotrichia. Colour: brown above, with underside of snout and abdomen abruptly black, with an extremely narrow elongated black mark running above, in front and behind pelvic fins, and other elongated black marks at caudal fin base and along its axis.
