Épines dorsales (Total) : 2; Rayons mous dorsaux (Total) : 8; Épines anales: 2; Rayons mous anaux: 7; Vertèbres: 37. A generalized Characidium with the isthmus scaly and the breast rounded, iii external pectoral rays and i external pelvic ray, the eye only slightly oblique, the lateral line complete and the adipose fin present; zebra-like color pattern; characterized by only ii,8 dorsal rays and few (5/5) teeth on both jaws, essentially conical, with apex of the mandibulary teeth somewhat enlarged, triangular, and probably no second mandibulary row and no pterygoid teeth. 'Spines' refer to unbranched rays.

A limitroph species (Ref. 38397).

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=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.3 se; based on size and trophs of closest relatives

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