Description synthétique
Clés d'identification | Morphologie | Morphométrie
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).
Body shape (shape guide): fusiform / normal.
This species occurs sympatrically with X. mixei and apparently prefers deeper pools; in rapidly flowing river with boulders and riffles (Ref. 52914).
