Short description
Identification keys | Morphology | Morphometrics
This species is distinguished by the following unique barbel structure: barbel moderately long, its length 65.3% SL; terminal bulb is small, its length 1.2% SL; 3 terminal filaments, one of which is thicker than the others with few pigmentations near base, all filaments simple and lacking bulblets and secondary branches; longest filament length 4.1% SL; axis of stem weakly pigmented; presence of a distinct ring-shaped black spot surrounding base of bulb; further unique meristic characters are - anal-fin rays 35; IP 7; PV 34; VAV 19; OV 31; VAL 19 (Ref. 121636).
This species was collected from a depth shallower than 100 m, by a mid-water trawl that was targeting the Sakura-shrimp (Lucensosergia lucens) (Ref. 121636).
