Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Barbel with three small unpigmented branches arising from stem; medial branch length less than 20% of distal barbel; lateral branch lengths less than 50% of distal barbel; distal tip of terminal bulb with two prominent medially based filaments each with numerous small, short side filaments; a similar, shorter filament and several simple filaments ventral to these (Ref. 45801).
Epi- and mesopelagic (Ref. 58302).
