Chamyla and Isochlora requires a further revision, especially as the genitalia of the type species of the subgenus, Chamyla idia STAUDINGER, [1900] 1899 (= arctomys ALPHÉRAKY, 1897) shows close connections with the type species of Isochlora, I. viridis. Thus, the revision of the entire genus would be desirable. However as more than half of the taxa belonging to the genus were discovered and described in the last fifteen years, it seems plausible to wait with the monographic treatment of Isochlora until the increase of the species numbers stopped. The two other species of the lineage are known from the Himalayan-Sino-Tibetan region. The newly discovered Isochlora balinti sp. n. is the first member of the group which occurs outside the supposed main centre of speciation of the entire genus. DESCRIPTION OF THE NEW SPECIES Isochlora balinti sp. n. (Figs 1-4,9) Type material - Holotype: male, Kyrgyzstan, Yssyk-Köl region, Inner Tien Shan Mts, Terskey-Ala-Too Mts, 10 km SW of Barskoon-pass, 3820 m, N41°50'32, E77°43'54, 17.VII. 2007, leg. J. BASICS & T. CSŐVÁRI, slide No. RL9299; deposited in the Hungarian Natural History Museum (HNHM), Budapest, Hungary. Paratypes: 3 males, Kyrgyzstan, with the same data as the holotype; slide No. BJ292, deposited in HNHM. Diagnosis - The new species differs from the related /. salki GYULAI et RONKAY, 1997, and /. glaciale (BOURSIN, 1940) by its darker, better discernible olive-brown antemedial and postmedial crosslines and the conspicuous light greyish-ochreous cilia on both wings (Figs 1-6). The male genitalia of /. balinti sp. n. (Fig. 9) differ from those of /. salki (Fig. 11) by their trapezoidal fultura inferior, narrower, evenly tapering valva, longer, more flattened harpe and the shorter, thicker uncus; from those of /. glaciale (Fig. 10) by their shorter but broader uncus being broadest at medial third (that of/, glaciale it is evenly tapering from its base towards apex), shorter and narrower vinculum and the somewhat different shape of the harpe (that of /. balinti is slightly tapering towards apex while in /. glaciale the harpe is apically more dilated, rather sponge-biscuit-like).
