Short description
Identification keys | Morphology | Morphometrics
Barbel with five simple, tapering branches apparently arising together from main stem (lateral pair actually arising from the bases of the medio-lateral pair just distal to stem); medial branch longest, its length three times distal barbel; stem pigment extending up to terminal bulb; bulb short, barely greater in diameter than stem, bearing a single simple terminal filament (Ref. 45801).
Body shape (shape guide): elongated.
Epi- and mesopelagic (Ref. 58302).
