Short description
Khóa để định loại | Hình thái học | Sinh trắc học
This species is distinguished from its congeners in Myanmar by the following characters: in life, with reddish cheek, series of up to 5 semicircular concentric maroon pectoral bands that are wider than interbands, series of 6-7 saddle-like blotches, orange subdistal and white distal rim on dorsal- and caudal fins; differs from C. stewartii by having fewer dorsal-fin rays 34-38 (vs. 39-41), and generally fewer anal-fin rays 23-25, rarely 22 or 26 (vs. 26-27); differs from C. burmanica by presence of pelvic fins (vs. absence); differs substantially from all Myanmar Gachua group snakeheads by a genetic distance of 12.9-18.5% in the COI gene (Ref. 131044).
Collected from small mountain streams near Kyeinthali in the southern Rakhine Yoma and from small remnant puddles beneath large boulders in the otherwise dry bed of a small tributary stream of Dalet Chaung in the middle Rakhine Yoma, and Laymyo River in the northern Rakhine Yoma, respectively (Ref. 131044)..
