Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 2; Rückenflossenweichstrahlen (insgesamt) : 8; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 7; Wirbelzahl: 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.
Body shape (shape guide): fusiform / normal; Cross section: circular.
A limitroph species (Ref. 38397).
