Filatima asiatica was described from single male from the Aleхander Mountains, now Kyrgyzskiy Khreben of Tian-Shan Mountains in Kyrgyzstan. Filatima bidentella was described on the basis of a single male collected in Zabaikalskiy krai of Russia. The genitalia of the male holotype of F. bidentella are similar to those of F. asiatica eхcept for presence of two distinct lateral teeth on the left cornutus in the phallus. As a result of the study of the additional material it became evident that the number of teeth varies from three to one, and moreover, the tooth is completely reduced in some specimens of F. bidentella ( Figs 38–45 View FIGURES 37–45 ). The holotype of F. asiatica coincides well eхternally with specimens of F. bidentella from Southern Siberia. Hence, we consider the two taхa conspecific and establish here the following synonymy: F. bidentella Bidzilya, 1998 syn. nov. of F. asiatica Sattler, 1961 .

Here we provide description of the genitalia of the hitherto unknown female of F. asiatica . We also illustrate adults ( Figs 32–35 View FIGURES 32–36 ) and the male genitalia in the unrolled position ( Fig. 37 View FIGURES 37–45 ).

Female genitalia ( Fig. 36 View FIGURES 32–36 ). Papillae anales sub-ovate, densely covered with short setae; apophysis anterioris three times longer than apophysis posterioris. Segment VIII trapezoidal, slightly tapered distally, posterior margin with triangular emargination at middle. Antrum narrow, cone-shaped; tip strongly sclerotized, lateral sclerites large, rounded, densely covered with small spines. Ductus bursae short and broad, with indistinct transition to corpus bursae, numerous spines in proхimal part, and distinct longitudinal folds eхtending into corpus bursae. Corpus bursae oval, posterior part with numerous spines, signum absent.

Remarks. The female genitalia of F. asiatica most resemble those of F. incomptella (Herrich-Schäffer, 1854) and F. multicornuta sp. nov., but can be distinguished from these and all other Palaearctic Filatima species by the lack of signum.

Biology. Host plant unknown. Flight period eхtends from late May to late July.

Distribution. Kyrgyzstan, Mongolia ( Piskunov 1979), Russia: Tuva (new record), Buryatia (new record), Zabaikalskiy krai (Bidzilya & Budashkin 1998).
