সনাক্তকারী নির্দেশক | বহিঃ অঙ্গ সংস্থান | মরফোমেট্রিক্স
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).
