Short description
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 19 - 20; Mjukstrålar i analfenan: 22 - 23; Ryggkotor: 34 - 35. This species is differentiated from its congeners in having the following characters: elongated dorsal fins in males; caudal spot diamond-shaped; humeral spot vertically elongated; maxillary teeth hexacuspidate; anal fin rays 22-23; lateral line scales 30-31 (Ref. 72430).
Inhabits shallow, clear water stream located in the Cerrado region; sandy bottom with small rocks and sparse aquatic vegetation (Ref. 72430).
