Eupithecia basurmanca Mironov & Ratzel , sp. n.

( Fig. 7 )

Material Examined. Holotype: Ƥ, Iran, prov. Mazandarăn, 1 km E of Razan, 1190 m, 9.v.2000, leg. Szabó & Hentschel, coll. Manfred Sommerer, Mironov slide no. 881Ƥ ( ZSM).

Differential diagnosis. The single known specimen (holotype) is relatively worn. E. basurmanca sp. n. is very similar externally to the Saudi-Arabian E. maerkerata Schütze, 1961 but distinguishes from this species by the longer fore wing with narrower apex and more oblique termen. From the other side, no significant differences can be found in the colour and pattern of wings between these two species, because the holotype and paratypes of E. maerkerata are also worn. The female genitalia of E. basurmanca clearly differs from those of E. maerkerata in the different shape of bursa copulatrix, different disposition of spines in corpus bursae, heavily sclerotized ductus bursae and different shape of colliculum ( Schütze 1961b). According to the structure of the female genitalia, E. basurmanca probably belongs to the graphata group, which is the most species-rich group of the genus in the Mediterranean region and Middle East. The female genitalia are rather similar to those of E. elissa Dietze, 1910 from Northern Africa. However, in the new species bursa copulatrix narrower, ovate; spiniferous area in the corpus bursae smaller; ductus bursae heavily sclerotized and without longitudinal wrinkles; colliculum broader than in E. elissa ( Schütze 1961a) .

Description. Wingspan 22.0 mm; fore wing 12.0 mm. Labial palpi short, obtuse, shorter than diameter of eye, covered with pale brownish scales. Frons, vertex and notum unicolorous, pale brownish. Fore wing with straight costal margin, slightly curved terminal and anal margins; ground colour ochreous brown; transverse lines inconspicuous, more or less well visible only postbasal, antemedial and postmedial lines; terminal area broad light brownish; whitish subterminal line indistinct, terminal line broad, brown, interrupted by vein ends; discal dot brown, narrow and elongate. Hind wing slightly paler, ochreous brownish, darkened to terminal area; all transverse lines and discal dot inconspicuous. Fringe on all wings slightly chequered with light and dark ochreous brown. Female genitalia ( Fig. 17 ). Bursa copulatrix ovate, membranous, slightly sclerotized at right spineless side under base of ductus seminalis, covered with small spines about one half along left side; marginal spines stronger sclerotized than other and with oblique row of longer spines from base of ductus seminalis to the base of colliculum. Ductus bursae heavily sclerotized, especially at right side between ductus seminalis and colliculum. Ductus seminalis broadened at base, sharply curved backward, attached to posterior part of corpus bursae. Colliculum collar-like, relatively broad, slightly inclined to right. Antrum narrow, membranous. Tergite A8 rectangular with shallow medial hollow in posterior margin and rounded posterior corners. Anterior and posterior apophyses short and narrow. Papillae anales short, broad, rounded, covered with short and medium sized setae. Male. Unknown.

Distribution. Iran (province Mazandaran).

Etymology. From “ Basurmanca ” (or ‘basurmanka’), an old popular and literary Russian word, which means a women adherent to a different faith (or also stranger per Russian history).
