DESCRIPTIONS OF THE NEW SPECIES Isochlora hoferi sp. n. (Figs 1,8) Type material - Holotype: female, Tadjikistan, Hissar Mts, Karatag R, Angisht Pass, 3000-3490 m, 25-30. 07. 2003; leg. W. PEREPECHAENKO, slide No. 2071 GYULAI; coll. P. GYULAI (deposited in the Hungarian Natural History Museum Budapest = HNHM). Taxonomy - The species content of the genus has been remarkably increased in the last fifteen years, due to the recent, intensive exploration of the fauna of the Inner Asian high mountains and the Tibetan plateau (GYULAI & RONKAY 2001,2006b, HREBLAY et al. 1998, RONKAY & GYULAI 1997,2006, etc.). The actual checklist of the genus counts more than 25 species and subspecies, but the future collectings will presumably lead to the discovery of several further taxa; some of them, like the species under discussion, may represent still unknown phyletic lineages within this complex and from a taxonomic point of view rather difficult genus. Diagnosis - No similar Isochlora species is known; the black banded milky white wings are unique within this genus. The configuration of the female genitalia of the new species resembles mostly I. metaleuca RONKAY et GYULAI, 1997 but the appendix bursae of the new species is more elongated, the corpus bursae is not ovoid but saccate, the ratio of length of the apophyses anteriores and posteriores is different in the two species, as well as the shape of the ostium bursae and ductus bursae. Description - Female (Fig. 1). Wingspan 27.5 mm (apex of right fore wing incomplete, broken), length of fore wing 15.0 mm. Pubescence of head and thorax dark brown to black; palpi greyish-ochreous, with long, sparse black hairs. Eyes almond-shaped, dark brown; antennae fine, more or less filiform, upper side dark brown with whitish scales, ventral side more reddish-brown. Legs brown, tibiae with long, bushy black hairs. Fore wings and hind wings milky white with very conspicuous black markings: inner area, broad median stripe and marginal field almost entirely black, with a few whitish-grey scales mainly in marginal area; terminal line also black. Other elements of wing pattern absent, although reniform stigma and discal spot of hind wing somewhat darker than black median stripe. Cilia also blackish but somewhat lighter than marginal area, having fine silky sheen. Underside of wings similar to upperside but generally lighter, almost entirely milky white with some ochreous shade and pale brown suffusion in basal and marginal fields. Shadows of stigmata and medial stripes conspicuous, practically same as on upperside but more intensive on hind wing; cilia as on upperside. Male unknown. Female genitalia (Fig. 8): Ovipositor strong, elongated-conical, heavily sclerotized. Papillae anales scarcely setose, apophyses postetiores long, apophyses anteriores less than half long as apophyses posteriores. Lamina postvaginalis rather calyculate; ostium bursae
