Short description Identification keys | Morphology | Morphometrics

Distinguished from all of its congeners by having a homogeneous dark-brown caudal-fin coloration pattern. Can be differentiated from Batrochoglanis acanthochiroides by having a deeper head (39.5-46.2 vs. 26.0-38.7), a wider pectoral girdle (30.7-31.9 vs. 28.4-30.4), and a longer adipose-fin base (16.0-21.5 vs. 12.5-15.50); from B. raninus by having a deeper head (39.5-46.2 vs. 29.0-39.4); and from B. transmontanus by having a longer adipose-fin base (16.0-21.5 vs. 11.5-14.3), and a longer pelvic-fin length (19.8-22.4 vs. 14.0-16.3) (Ref. 56694).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
