Diagnosis.

Adult ( Fig. 5 ) with wingspan 12.0-15.0 mm. This species is similar to Cochylis dubitana , but Cochylis posterana hyrcana can be distinguished by the median process of the transtilla nearly triangular, the sacculus with a small terminal process, and the phallus with more than ten cornuti in the male genitalia ( Fig. 10 ). In Cochylis dubitana , the median process of the transtilla is nearly triangular on basal 3/4 and slender on distal 1/4, the sacculus does not bear terminal process, and the phallus does not have cornutus in the male genitalia. The female genitalia ( Fig. 15 ) are similar to those of Cochylis hybridella , but Cochylis posterana hyrcana can be distinguished by the antrum consisting of two rounded plates close to each other and the absence of a cylinder-shaped structure at middle. In Cochylis hybridella , the antrum is a nearly rounded plate bearing an approximately cylinder-shaped structure at middle in the female genitalia.

Distribution.

China (Gansu, Xinjiang), Iran. The nominate subspecies occurs in Europe.

Remarks.

The type locality of Cochylis posterana posterana Zeller, 1847 is Hungary. Then it was reported to occur in different countries of Europe. Cochylis posterana hyrcana can be distinguished from Cochylis posterana posterana by the forewing with median fascia conspicuous anteriorly, the median process of the transtilla nearly triangular in the male genitalia. In Cochylis posterana posterana , the median fascia is invisible anteriorly in the forewing ( Razowski 1970: Taf. 26, Fig. 273), and the median process of the transtilla is uniform in width in the male genitalia ( Razowski 1970: Taf. 106, Fig. 273).
