Μέγεθος / Βάρος / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.2 cm SL αρσενικό/απροσδιόριστο; (Ref. 11333); 15.3 cm SL (female)
Μαλακές ραχιαίες ακτίνες (συνολικά) : 25; Μαλακές εδρικές ακτίνες: 40; Σπόνδυλοι: 68. A single terminal bulb, its length more than twice its width, with a very short or no terminal projection. Bulb and projection combined 0.4-1.6% SL. Barbel 35-57% SL. Axis of stem moderately pigmented proximally, usually becoming lighter distally. External chevron-shaped or roundish striated areas unpigmented, becoming closely spaced distally. Spherical to ovoid inclusions present in distal half of stem, small and widely spaced proximally, becoming fairly crowded distally, difficult to discern in specimens smaller than about 9 cm SL. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 7 or 9 (Ref. 11333).
Mesopelagic (Ref. 58302).
