Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
A species characterized by a longer caudal appendage, sword index 0.25; fainter orange stripes that fade in older individuals and pronounced melanophore pigmentation at the edges of the dorsal and ventral sword margins (in males) (Ref. 52914).
This species occurs sympatrically with X. mixei and apparently prefers deeper pools; in rapidly flowing river with boulders and riffles (Ref. 52914).
