Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 9; Raios anais moles: 7 - 8; Vértebras: 40. Distinguished from most of its congeners, except Ituglanis macunaima and Ituglanis parahybae, by having a pectoral fin ray count of I,4. Differs also from all its congeners, excluding Ituglanis parahybae, by the coloration pattern with longitudinal rows of coalescing blotches.

Bayesian length-weight: a=0.00661 (0.00282 - 0.01550), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

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