This species can be distinguished from all congeners except K. chapadae and K. geryi by the following characters: 6 rows of scales between the lateral line and the dorsal-fin origin (vs. 4 or 5 rows); differs from K. chapadae by possessing 5 rows of scales between the lateral line and the pelvic-fin origin (vs. 3½ or 4); 38-41 lateral line scales (vs. 36-38); differs from K. geryi by having 5 rows of scales between the lateral line and the pelvic-fin origin (vs. 4); 17-20 branched anal-fin rays (vs. 15-17), and in lacking the 2 symmetric, large, dark, blotches, which are present on the base of the caudal-fin lobes in K. geryi (Ref. 75798).

The are of occurrence, río Shinahota, is a typical Andean piedmont drainage, with medium water velocity; mainly gravel and pebbles substrate; some years the river has an intermittent flow. This riparian forest is degraded and the river polluted by domestic waste (Ref. 75798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00443 - 0.02057), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

جهندگی (Ref. 120179): زياد, كمينه زمان لازم براي دو برابر شدن جمعيت ، كمتر از 15 ماه (Preliminary K or Fecundity.).

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