Diagnosis

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.
