This species is distinguished from all its congeners by the following characters: middle caudal-fin rays dark (vs. hyaline or with a small dark patch at base of middle caudal-fin rays on callolepis); differs further from arnoldi by having the procurrent caudal-fin rays black (vs. hyaline); differs from compta by having 14±15 scales on the first longitudinal scale row (vs. 16±17); differs from nattereri by the absence of a black spot on the

posterior portion of each body scale (vs. presence); differs from callolepis by the absence of a series of conspicuous clear spot on each scale of the fourth longitudinal scale row (vs. presence); males differs from those of vilmae by the absence of discontinuous longitudinal series of dark scales on body (vs. continuous), and from females of vilmae by the absence of a small dark spot at the base of the upper caudal-fin lobe (vs. presence) (Ref. 137764).
