Midlateral stripe prominent, vertical bars less intensive; black spots in dorsal, anal, and caudal fin; dark spots on the opercle and anterior flank scales. Distinguished from both C. facetum and C. tembe by having 8-9 anal-fin spines [vs. 6-7 (rarely 5 or 8), 5-7, respectively], 13-14 anal pterygiophores (vs. 12-13, 11-12, respectively), modally 17 dorsal-fin spines (vs. 16), and modally 6 gill rakers on first ceratobranchial (vs. 8, 7-8, respectively). Further distinguished from 'C.' facetum in having 14 caudal vertebrae (vs. 13) and from 'C'. tembe by a shorter caudal peduncle including only one or no vertebral centrum (vs. 3). Jaw teeth lack the second cusp (also in tembe vs. present in facetum (Ref. 51414).

ຊີວະສາດ     ຄຳແປສັບ (ຕ.ຢ. epibenthic)

Found in a large stream about 10 meters wide, the water mostly shallow, less than 1 meter deep; bottom of mixed rock, sand, and gravel, providing riffles; slightly brownish and turbid. Radiographed specimens reveal considerable amounts of small shells in the guts and intestines. The stout lower pharyngeal bone consistent with a snail diet (Ref. 51414).
