Material examined: Brazil, Rio de Janeiro: MCP 28604, neotype, male, 23.3 - mm SL; UFRJ 5404, 1; UFRJ 5355, 24; UFRJ 5403, one; UFRJ 5356, 4 (c & s); UFRJ 5220, 6 (c & s); temporary pool, Vila de Cava, Nova Iguaçu; CAS (SU) 36523, holotype of C. zingiberinus; CAS (SU) 36524, ten paratypes of C. zingiberinus; MNRJ 4739, eight syntypes of C. sicheleri; base of serra de Petrópolis. Diagnosis: Distinguished from all congeners by having asymmetrically lanceolate caudal fin, with convex dorsal profile and straight ventral profile (vs. caudal fin symmetrical), urogenital papilla attached to anal fin in males (vs. urogenital papilla free), thickened tissue on anterior portion of anal fin in males (vs. never thickened), white stripe with narrow black border on ventral edge of caudal fin in males (vs. no similar colour pattern), and posterior half of flank dark brown with horizontal rows of yellow spots, coalesced to form stripe on lateral midline of caudal peduncle in males (vs. no similar colour pattern). Remarks: Redescribed by Costa (2002 b). Distribution: Estrela and Iguaçu river basins: two small, isolated basins draining into Guanabara bay, Rio de Janeiro state, south-eastern Brazil (
