背的軟條 (總數) : 11; 臀鰭軟條: 27 - 31; 脊椎骨: 36 - 37. Distinguished from all species of the genus and from all remaining characids by having a unique color pattern consisting of the combination of presence of a conspicuous, narrow dark midlateral stripe, a single elongated humeral spot, and upper caudal-fin lobe and middle
caudal-fin rays dark, with a clear, rounded ocellated spot present dorsally at anterior third of caudal-fin lobe (Ref. 81201).
