deskripsi pendek
Morfologi | Morfometrik
Sirip dubur lunak: 205 - 228. Distinguished by the following combination of characters: gape relatively long, the rictus falling short posteriorly of the vertical through the posterior naris; the anteroposterior length of premaxilla equal to the transverse width; teeth on the dentary occupying most of the dorsal margin; two or three teeth arranged in a single row on the internal surface of the endopterygoid; 15-17 scales above the lateral line at the midbody; the length of the coronomeckelian bone less than 20% the length of Meckel’s cartilage; length of the
posterior ceratohyal 1.5 times the length of the ventral hypohyal; the length of the caudal filament 16.0-25.7% LEA; depth of the caudal filament 5.6-11.2% CL; presence of a narrow dark stripe along the lateral line and a broad band of dusky to dark pigmentation overlying the basal pterygiophores of the anal fin; 19-21 pectoral-fin rays; 205-228 anal-fin rays; head
length at the opercle 13.5-14.7% LEA (Ref. 93148).
Collected in river with pronounced current that was faster towards the centre of the channel, with the substrate in the sampled areas formed by pebbly sand. Also found in the main stream of shallow rapids and small waterfalls, always over a rocky bottom (Ref. 93148).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00214 (0.00126 - 0.00364), b=2.89 (2.73 - 3.05), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (30 of 100).
