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).
