Type material. Holotype ♂ ( GP 5654 J. Tabell, DNA sample 25452 Lepid Phyl): Kazakhstan, 43°17´44´´N 78°59´27´´E, Charyn River , 1005 m, 31.V.2014, K. Nupponen & R. Haverinen leg., coll. NUPP.GoogleMaps  Paratype 1 ♂ (GP 5337 J. Tabell, DNA sample 25451 Lepid Phyl) same collecting data as in holotype, coll. NUPP.

Diagnosis. In male genitalia C. charynensis  sp. nov. is close to C. trichopterella  and C. mirleftensis  sp. nov. A large fold at the outer margin of valvula is characteristic and distinguishes the new taxon from all close relatives.

Molecular diagnosis. Both type specimens were sequenced successfully, resulting in identical full 658 bp DNA barcode fragments. The sequences revealed 5.79–11.77 % divergences from other barcoded taxa (Table 1). Compared to C. trichopterella  (n = 1) and C. mirleftensis  (n = 3) the barcode gap is 7.75 % and 7.05 %, respectively.

Description. Wingspan 12.5–13.0 mm. Head white. Antenna unicolorous pale ocherous. Scape white. Labial palpus slightly ascending, white, not tufted, second segment 1.5 x longer than third segment. Thorax and tegula white with mixed pale ochre. Forewing pale ochre, costa broadly white, fringes whitish grey. Hindwing pale grey, fringe whitish grey.

Abdominal structures. Latero-posterior bar thick, 2/3x length of latero-anterior one. Transverse bar slightly concave, proximal edge thin, sclerotized only medially, distal edge very thick, medially strongly constricted and bulged. Tergal sclerite 6x longer than wide, covered with 45 conical spines (on T3).

Male genitalia. Gnathos knob transversely oval. Tegumen moderately short, medially slightly constricted, pedunculus long. Transtilla elongate, wedge-shaped, bent downwards. Cucullus thimble-shaped, narrow, not extended to tip of sacculus. Valvula broader than cucullus, weakly delineated, outer margin with large elongate fold. Sacculus elongate, bifurcate; ventral margin oblique, slightly convex, terminating in small triangular protuberance; lateral margin short, concave, dorsal process blunt, triangular, exceeding apex of cucullus; dorsal margin convergent with lower margin of cucullus. Phallotheca a well sclerotized elongate tube. Vesica partly well sclerotized, with two long cornuti grouped with a basal plate.

Female genitalia. Unknown.

Biology. The immature stages and larval host plant are unknown. The specimens came to light at night. The habitat is a steep river canyon with rocky steppe slopes on both sides.

Distribution. So far the new species is only known from the type locality in the Charyn River canyon, south- eastern Kazakhstan.

Derivation of name. The specific name refers to Charyn River, which flows in the vicinity of the collecting
