型態特徵 | 形態測量圖
脊椎骨: 137. This species is distinguished by the following set of characters: with a single row of slightly enlarged dermal denticles along the dorsal midline extending between level just anterior of posterior insertion of pelvic fins and anterior base of first dorsal fin and continuing rearwards along dorsal ridge of tail between first and second dorsal fins; a few large denticles on top of the head; nasal flap squared with a fine fringe on ventral edge; two short lateral barbels bluntly rounded also with a fine fringed margin; males with a dorsal color pattern of small, scattered, dark spots distributed over a uniform light-brown background; pectoral-fin span 52.0-58.1% TL; pelvic-fin span 30.7-31.0 % TL; pre-pectoral-fin length 19.4-19.8% TL; trunk width 18.1-19.5% TL; head length 16.5-17.5% TL; spiracle length 2.2-2.3% TL; eye-to-spiracle length 2.2-5.0 % TL; mouth width 10.5-12.1% TL; nostril width 1.6-2.3% TL; snout-to-pectoral distance 19.4-19.8%; spiracle width 2.2-2.3% TL; pectoral-fin inner margins 17.5-18.3% (Ref. 125651).
