Abstract. Cremastus kasparyani sp. n. from Turkey is described. The new species is distinguished from all Western Palaearctic species by swollen and partly flattened from below trochantellus of hind leg. Key words. Cremastus, new species, Turkey, Ichneumonidae, Hymenoptera.

Introduction The genus Cremastus Gravenhorst, 1829 is widely distributed in the Holarctic region and com- prises 94 species in the Nearctic region (Dasch, 1979), 30 species in the Palaearctic region, and two species in the Afrotropical region (Yu et al., 2012). Species of this genus are koinobiont endoparasitoids of Lepidoptera and, less commonly, Coleoptera larvae in tunnels, leaf rolls, buds, galls and other similar concealed habitats (Wahl, 1993). Key to Western Palaearctic species was proposed by Kolarov (1997). Until now, 11 species of Cremastus were known from Turkey (Kolarov, 1997; Kolarov et al., 2002; Kola- rov, Yurtcan, 2009; Çoruh et al., 2013). A new species was found in materials from south Turkey. Speci- mens of this species were collected on meadows close to coniferous forest by standard entomological net.

Taxonomic part

Cremastus kasparyani sp. n. Description. M a l e . Fore wing 3.2 mm, body 4.9 mm long. Head weakly and roundly narrowed behind eyes (Fig. 1). Lateral ocellus small, its diameter 0.7 times as long as oculo-ocellar line. Frons slightly concave above bases of antennae. Flagellum of antenna with 30 segments; all segments elongate, first segment 3.6 times as long as wide. Inner orbits of eyes slightly divergent downwards; face 2.1 times as wide as long (Fig. 2). Clypeus 3.9 times as wide as long, with weakly convex apical margin. Mandible large with equal teeth. Malar space 0.8 times as long as basal width of mandible. Occipital

114 carina weak, joining the hypostomal carina close to base of mandible. Temple 0.7 times as long as transverse diameter of eye. Frons matt, face rather coarsely and densely punctate, the distance between punctures as long as its diameter. Clypeus and temples with sparse punctures only. Mesosoma 1.8 times as long as high. Notaulus extending to the middle of mesonotum, but shallow. Prepectal carina reaching hind margin of pronotum at its mid-height. Propodeum fully areolated. Basal area pointed posteriorly. Areola pen- tagonal, 2.1 times as long as wide (Fig. 5.). Combined basal area and areola 1.5 times as long as petiolar area. Propodeal spiracle small, of equal distance from lateral and pleural carina. Fore wing with pterostigma 2.5 times as long as wide, first section of radius originated posteriorly its mid-length (Fig. 3). Metacarp a little longer than intercubitus (9 : 7). Basal vein slightly arched. Nervulus antefurcal; second recurrent vein distinctly postfurcal. Parallel vein connected with postnervulus a little above the middle. Hind wing with four distal hamuli. Nervellus indistinctly intercepted below middle, discoidella not pigmented. Legs slender, hind femur 3.4 times as long as wide. Trochantellus of hind leg swollen and partly flattened from below (Fig. 4). Ratio of hind tarsomeres length as 28 : 12 : 10 : 7 : 8. Tarsal claws simple. Metasoma compressed from third segment. First metasomal segment almost straight, 3.5 times as long as wide posteriorly; glymma present. Postpetiole and second tergite finely longitudinally striate, following tergites matt. Black. Inner orbits, outer orbits partly, clypeus, mandible, front surface of fore femur, front surface of middle femur except base, trochantellus from below, tegula and base of pterostigma yellow; tibiae with indistinct subbasal whitish ring; second tergite yellow-red apically; legs (except coxae and trochanters) brown, greater part of tibiae from above dark yellow. F e m a l e . Unknown. Type material. Holotype: male, Turkey, Isparta, Gölcük, 1200 m, 7.VI.2004 (University of Plovdiv, Bulgaria). Paratypes. Same data as holotype, 2 males. Etymology. The new species is dedicated to famous Russian ichneumonologist Dr Dmitri R. Kas- paryan for his contributions to Ichneumonidae taxonomy. Comparison. The new species is close to C. geminus Gravenhorst, 1829, but differs by its smaller ocelli, longer malar space, swollen and partly flattened from below second trochanter of hind leg, smaller body size and coloration. In the identification key to the Western Palaearctic Cremastus species (Kolarov, 1997), the new species runs to the couplet 15. It can be included in this key with the following modification: 15. Clypeus wide, weakly convex, with almost straight front edge...... 15A – Clypeus narrow, moderately or strongly convex, with front edge curved outwards ...... 17 15A. Trochantellus of hind leg swollen and partly flattened ventrally...... Cremastus kasparyani sp. n. – Trochantellus of hind leg not swollen and not flattened from below...... 16
