Eup[ithecia] bastelbergeri Dietze, 1910, Biologie der Eupithecien 1: pl. 73, fig. 360. Syntypes 2♀ (coll. K. Dietze in MNHU; examined), Turkestan [Kyrgyzstan]: Naryn; Karagai-tau.

E[upithecia] bastelbergeri korvaci Prout, 1938, in Seitz, The Macrolepidoptera of the World, 4 (Suppl.): 188. Syntypes 3♀ (BMNH; examined), [Turkey]: Kurdistan, Malatya.

A generally small species (but of variable size) in the “ haworthiata ” group. Very small specimens from Kurdistan (Turkey) were described as subsp. korvaci Prout, 1938, but similar specimens have also been collected in Turkmenistan. In our opinion, korvaci is not a good subspecies but simply a small form, since normal-sized specimens are also found in Turkmenistan along with very small specimens. E. bastelbergeri flies from mid-June to early August, and perhaps early September. Larvae were found on Clematis orientalis L. ( Ranunculaceae) in October (Tajikistan: Degtjareva, 1973). It is likely that eggs are laid in the seed-balls of this foodplant because the females have elongate and heavily sclerotized papillae anales. This species occurs in Turkey, Caucasus (Daghestan), Turkmenistan (Kopet-Dagh Mts.), Uzbekistan, S. Kazakhstan, Kyrgyzstan and Tajikistan. A new species for the fauna of Mongolia. The male and female genitalia of this species were first described and illustrated in Viidalepp (1988).
