Etymology: Imparfinis: Latin, impar = unequal + Greek, finis, pinna = wing, fin (Ref. 45335); usmai: Dedicated to Saulo Usma for his contributions to
the ichthyological collection building in the Cauca valley, and for promoting an active interchange between Colombian and Venezuelan ichthyologists, since his MSc studies in 2000 at Universidad Nacional Experimental de los Llanos Ezequiel Zamora (Guanare, Venezuela) (Ref. 88952).

简单描述
型态特徵 | 形态测量图
Small heptapterid catfish (largest specimen 100.8 mm SL), with elongated body, triangular in cross-section at dorsal-fin origin, progressively more laterally compressed to tail region. Dorsal profile slightly convex from snout tip to dorsal-fin origin, slightly concave just posterior to dorsal-fin base to adiposefin origin, straight and descending along adipose-fin base, then ascending along caudal peduncle. Ventral profile of head straight, slightly convex along abdomen, then straight to analfin origin and slightly descending along caudal peduncle (Ref. 88952).
