Etymology: Cyphocharax: Greek, kyphos = curved, humpback + Greek, charax = a marine fish without identification (Ref. 45335); pinnilepis: The specific name 'pinnilepis' is derived from 'pinnis', meaning fin, and 'lepis', meaning scale, in allusion to the presence of a patch of scales over basal portions of caudalfin lobes.

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Raios dorsais moles (total) : 12; Raios anais moles: 9 - 10; Vértebras: 31 - 33. The following combination of characters diagnosed this species from all its congeners: pored lateral line scales from the supracleithrum to the hypural joint 33-36; vertebrae 33-35; greatest body depth 33.5-39.3% of SL; distance from the snout to the anal-fin origin 76.2-83.4% of SL; least depth of the caudal peduncle 11.7-13.8% of SL; length of the postorbital portion of the head 33.8-41.5% of HL; interorbital width 32.8-43.8% of HL; presence in adults of a field of scales with a parabolic margin extending onto each lobe of the caudal fin; absence in adults of prominent dark stripes or spots on the body or a dark spot at the base of the caudal fin; and absence of a patch of dark pigmentation on the dorsal or adipose fins (Ref. 85320).
Body shape (shape guide): elongated.
Found in small rivers with relatively slow currents and somewhat turbid water and also in shallow areas of a reservoir along the Rio Gongogi. These areas have muddy substrates to some degree (Ref. 85320).
