Morphology | Morphometrics
Vertebrae: 36. Distinguished from all other characid fishes by the following combination of characters: infraorbitals fused uniquely, resulting in less than six autogenous bones; presence of a single tooth row in the premaxilla; presence of cheirodontin-like teeth, somewhat pedunculated, expanded and compressed distally, with cusps similar in shape and perfectly aligned along dorsal margin; ventral margin of toothed portion of maxillary curved towards the ventral margin of the premaxilla and maxillary teeth forming a continuous series with premaxillary teeth; margins of pre- and postzygapophyses with projections anteriorly and posteriorly directed; accumulation of epithelial cells forming globular structures distributed over head and scales; and base of anal-fin without scales covering basal portion of unbranched and anterior branched rays (Ref. 54751).
Found in shallow, headwater stream with fast water current over a rocky bottom and margin, with a small amount of riparian or submerged vegetation (Ref. 54751). Feeds on filamentous algae, terrestrial vegetal fragments and insects (Ref. 54751).
