Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 2; Mjukstrålar i ryggfenan (totalt): 8-10. This species is distinguished by the following characters: 10-11 pelvic-fin rays;; 14-15 (13) pectoral-fin rays; 20-24 total gill rakers; moderately long barbel, 11-15% HL and reaching vertical through anterior rim of orbit; orbit 28-30% HL; pointed and protruding snout, 17.5-20% HL; ventral striae extending to about ? to ½ the distance from pelvic fin bases to periproct; the otolith moderately compressed (OL:OH = 1.0-1.05); colliculi separated, small; pseudocolliculum small (TCL:PCL = 1.9-2.2) (Ref. 98298).
