Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 15 - 16; Raggi anali molli: 16 - 17. This species is distinguished from its congeners by the following set of characters: anal fin with a narrow dark brown submedial band, narrow yellow and orange medial bands, narrow white subdistal band, and slender dark brown distal band in males; caudal fin with irregular red-brown spots and stripes proximally and medially, followed by irregular narrow red-brown subdistal band and slender white distal band, with interrupted red-brown fin tips; body depth 31.935.5% SL; snout length 14-16% HL 21-31; and caudal peduncle length 119-125 in % of its depth (Ref. 138275).
Body shape (shape guide): fusiform / normal; Cross section: oval.
This species inhabits a turbid stream measuring 10 m in length, 1 m in width, and approximately 50 cm in depth, with margins overgrown by grass (Ref. 138275).
