Differential diagnosis. Externally, by two brown horizontal strokes on fore wings distally, the new species is similar to C. ludmilae Ustjuzhanin & Kovtunovich, 2011 (type locality Kyrgyzstan, Kashgaria, Taldy-Bulak creek, between Nura and Irkeshtam vil.), but differs in the darker wings and the male genital structure. In the new species, the right valve is wider than the left one; the harpe on the left valve is located medially on the costa, the uncus is short, the aedeagus is medially bent almost at right angle, while in C. ludmilae , both valves are of equal width, the harpe on the left valve is located on the costa basally, the uncus is long, the aedeagus is slightly wavy.

Distribution: Kyrgyzstan Republic, Inner Tian-Shan.

Etymology. The species is named after Russian entomologist Stanislav Korb (Nizhny Novgorod) who collected the specimen of the new species.
