Rayons mous dorsaux (Total) : 11; Rayons mous anaux: 8; Vertèbres: 43. Diagnosis: distinguished from the only congener, C. bamen by smaller predorsal length (43.7-47.3 % SL vs. 47.8-49.5), smaller prepelvic length (46.8-50.9 % SL vs. 51.2-52.1), shorter rostral barbel (14-24 % HL vs. 32-46), shorter maxillary barbel (28-39 % HL vs. 40-57) and different pharyngeal tooth pattern (2,4,5-? (1), 1,3,5-5,4,1( 1), 2,4,5-5,4,2( 2) or 3,4,5-5,4,3( 2) vs. 2,3,4-4,3,2) (Ref. 103410).
Body shape (shape guide): elongated; Cross section: circular.
Type specimens were collected in a large 10 m depth pool by gill net; water flow out from a hole at the bottom of the pool; the artificial pool have been built 1995; water of the pool had pH 7.7, water temperature 28.9 °C and dissolved oxygen 13.4 mg·1-1 at 20 cm under surface; and 23.2 °C and 7.4 mg·l-1, respectively, at 2 m depth (Ref. 103410).
