脊椎骨: 35. Absence of dark stripes on body; absence of concentric bands on paired fins. Pelvic fin reaching 5-40% of distance between anus and anal-fin origin. No cavity around the mouth, skin-fold between oropectoral membrane and ventral surface of head running from pectoral-fin origin to second rostral barbel. Tubercles on dorsal part of head concentrated on tip of snout; 15-21 large tubercles on branched pectoral-fin rays. General appearance elongated. Lateral line with 58-64 scales (Ref. 40433).
