C. perijae can be distinguished from C. torbesensis by the combination of the following characters: Head and caudal peduncle less depressed, 17.93% and 11.02% respectively; odontodes of the interopercular area short, the longest not reaching beyond the base of the pectoral fin; four plates between the supraoccipital and the origin of the dorsal fin; uniform color pattern, brown or dark brown to black.
C. perijae 能被与 C. torbesensis 区分藉由下列特徵的组合: 头部与尾柄比较不扁平, 分别地的 17.93% 与 11.02%; 间鳃盖骨区域短的齿, 不被超过胸鳍的基底的最长的; 在上枕骨与背鳍起点之间的四个碟; 均匀的彩色斑纹, 褐色或深褐色的到黑色的。
Collected from mountain rivers associated to humid tropical areas. From transparent waters, with strong to moderate current with river beds formed by rocks, small stones and sand, scarce or absent aquatic vegetation (Ref. 40935).
