Vojnits, A.: New Eupithecia species from Soviet Central Asia (Lepidoptera, Geometridae)

Eupithecia pamiri sp. n. Diagnosis — Average alar expanse of fore wings of 40 male specimens 21 mm, extreme values 17 and 24 mm ; that of 50 females 21.5 mm, extreme values 18.5 and 24.5 mm. Wings elongated. Costa and termen of fore wing arcuate, dorsum straight. Apex obtuse, termen obtusely angulate. Hind wing obtusely angulate. Fore wing light grey. Transverse stripes sharp, blackish near costa. Part of venation, especially in median field, also covered with black. Submarginal stripe white, contiguous, not disintegrated. Hind wing pale, transverse lines grey or black. Discal spot of fore wing velvety black, sharply defined, elongated or round, on hind wing indistinct. Underside of wings nearly white, pattern grey. Cilia long, striated greyish white and grey, very light on hind wing (Plate 1 : figs 4-5). Some specimens darker, some others again a part of pattern not or hardly discernible (Plate 1 : fig. 5). Genitalia — rf : Entire genitalia rather small, stout, short. Uncus thick, robust, bifid, but second apex very short. Valva short, evenly attenuating from base to obtuse apex. Pulvinulus a wide field. Ampulla elongated, terminally clavate, with its 50-60 short bristles. Falces projecting beyond uncus. Clavulus long, slender, scopulina short. Lamellula comparatively narrow. Aedoeagus short, thick. Vesica with a twisted, a dentiform and a very long, lamelliform sclerotized excrescence. Base of sternite VIII very wide, rapidly attenuating, arms narrow (Plate 4: figs 25-27). — $ : Bursa copulatrix elongated. Bursa evenly padded with minute spines ; from antrum a twisted tube extending into bursa, almost to its middle. Both anterior and posterior apophyses relatively short and medium long. Papillae anales almost quadratic. Shape of bursa and size of spinose field considerably varying (Plate 4: fig. 28). Biology — First stages and foodplant unknown. The known imagos were collected in JulySeptember. Distribution — Ranging in Soviet Central Asia, found in the Pamir and Altai areas. Locus typicus: Pamir merid., ccoid., Mts. Schachdarensis. Specific differences — The new species resembles Eupithecia costisignata DIETZE, but it is slightly larger, the grey shows no brownish or yellowish tint, and the transverse stripes are conspicuously defined. Also the male and female genitalia are similar to those of costisignata, the differences appearing only in details. Holotype rf : "Pamir, merid. occid. Mts Schachdarensis cliv. sepir, Fl. Seiojdara, 3250 m. 27.7.957 A. Bündel" "gen. prep. No. 17686 rf det. A. Vojnits". — P a r a t y p e s: 39rftf and 505 9 from the Pamir area, from Juli-September. Holotype deposited in the Zoological Institute, Academy of Sciences, Leningrad, and in the Hungarian Natural History Museum, Budapest.

A. Vojnits. Eupithecia mystica sp. n. Derivation of specific name : mysticus = mysterious. Diagnosis — Generally of an innotatoid type, both as to wing shape and pattern, but highly varying. Alar expanse of fore wings of male 18-25 mm, mean value 21 mm (based on 48 specimens), that of females 19-23 mm, mean value 21 mm (based on 34 specimens). Wing shape of two main types: a more elongated one, with costa of fore wing longer than dorsum, and a wider one, of an isosceles triangle. Costa and termen of fore wing slightly arcuate, dorsum straight, hind wing rounded, but in some specimens more elongated than in the others. Basic colour and pattern largely innotatoid, but eventually brownish, or yellowish, or grey, with transverse stripes obsolete or conspicuously defined, black discal spot either robust and alongated or small and rotund. Underside of wings accordingly with an obsolete or well defined pattern. Cilia medium long, striated fuscous and greyish yellow (Plate 1 : figs 6-7).
