Snout short, anterolateral margin incompletely supported by bone; orbits longer than snout and postorbital. Naked fossa of ventral light organ (ADW) relatively large, anterior end reaches about to line connecting pelvic fin insertions. Underside of head and nasal fossa naked; broad, naked, translucent areas dorsally behind leading edges of snout. A series of scales on midline of nape with median spinule row elevated into low crests, forming weak but distinct ridge from supraoccipital scute to dorsal fin. A series of 12-13 faint saddle marks, the anterior four directed anteriorly downwards. Pyloric caeca 15-16. Remarks: pelvic fin with slightly prolonged outer ray. |
