Differs from its congeners in Indochina by the combination of the following characters: males with rounded suborbital flap; caudal fin deeply forked; body with 7-14 dark bars on body irregularly shaped, often incomplete or joining another bar; head yellowish with small brown spots on top and cheeks; dorsal rays hyaline with a broad black band at mid-length of rays; processus dentiformis present; 9+8 branched rays in caudal fin; lateral line complete; axillary pelvic lobe present; eye smaller than interorbital width; predorsal area covered by scales; a complete black bar at caudal-fin base (Ref. 40772).
Collected in riffles (Ref. 40772).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00268 - 0.01487), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (22 of 100) .
