Type material.
Holotype, ♀ (RMNH), "Turkey; Agri, 30 km W [of] Eleskirt, 2200 m, 14.vii.1987, R. Hensen". Paratypes (6 ♀ + 2 ♂): 1 ♂ (RMNH), with same label data asa holotype; 1 ♀ (RMNH), "Turkey; Erzurum, Tortum, 1700 m, 16.vii.1987, R. Hensen"; 5 ♀ + 1 ♂ (BZL, RMNH), "Turkey east, Pasli, 50 km S [of] Sars, 1.vii.1997, Ma. Halada";
Diagnosis.
Head evenly convex dorsally, in front of occipital carina without medio-posterior depression; face wide (Fig. 225); frons and vertex with satin sheen and densely coriaceous-punctulate (Fig. 226); occipital carina narrowly lamelliform and dark brown (Fig. 220); mandible yellowish brown, but basally brown; propleuron 0.7 times as long as mesoscutum in front of tegulae and stout; antesternal carina narrow and non-lamelliform; middle lobe of mesoscutum with coarse punctures connected to rugulae, with satin sheen and interspaces largely smooth, lateral lobe similar but medially superficially coriaceous (Fig. 222); scutellum mainly transversely rugose; laterally mesosoma largely silvery pilose (Fig. 221); middle lobe slightly protuberant (Fig. 222); hind basitarsus dark brown basally, apically narrowly brown and remainder white or ivory; hind tibia distinctly swollen and with subbasal ivory ring (Fig. 227); hind basitarsus stout and 0.8 times as long as remainder of tarsus (without claws); ovipositor sheath 0.8 times as long as body, 1.3 times as long as metasoma, 2.1 times as long as hind tibia and tarsus combined and 3.4 times hind tibia; white or ivory apical part of ovipositor sheath 1.6-1.8 times as long as hind basitarsus; length of body 9-12 mm; hypopygium largely yellowish brown (Fig. 228); paramere broadly ivory apically (Fig. 231). Close to Gasteruption schlettereri Magretti, but the new species has the antesternal carina non-lamelliform (rather narrow lamelliform in Gasteruption schlettereri ), the hind tibia distinctly swollen (slenderer), the hypopygium yellowish brown apically (dark brown) and the hind basitarsus tricoloured and shorter than remainder of tarsus without claws (uni- and bicoloured of males and females, respectively, and about as long as remainder of tarsus).
Description.
Female, length of body 9.8 mm (of fore wing 4.9 mm).
Head. Head evenly convex dorsally, without medio-posterior depression; face, frons laterally and temples distinctly pilose; occipital carina narrowly lamelliform, dark brown (Fig. 220); third and fourth antennal segments 1.5 and 2.2 times as long as second segment, apical segment twice as long as penultimate segment; face wide (Fig. 225); frons and vertex with satin sheen and densely coriaceous-punctulate (Fig. 226); ventrally head not enlarged in anterior view, malar space 0.3 times as, long as second antennal segment.
Mesosoma. Length of mesosoma 1.6 times its height; propleuron 0.7 times as long as mesoscutum in front of tegulae, stout; ventrally pronotal side coriaceous with some large punctures and only posteriorly with pilosity, with a small blunt tooth antero-ventrally; antesternal carina non-lamelliform and narrow; middle lobe of mesoscutum with coarse punctures connected to rugulae, with satin sheen and interspaces largely smooth, lateral lobe similar but medially superficially coriaceous (Fig. 222); scutellum mainly transversely rugose; middle lobe slightly protuberant (Fig. 222).
Legs. Length of hind femur, tibia and basitarsus 4.4, 3.8 and 4.3 times their width, respectively; hind tibia distinctly swollen and ventrally curved (Fig. 227); fore coxa close to mesopleuron; hind coxa moderately transversely rugose dorsally; hind basitarsus stout, 0.8 times as long as remainder of tarsus, widened basally in dorsal view.
Metasoma. Ovipositor sheath 0.8 times as long as body, 1.3 times as long as metasoma, 2.1 times as long as hind tibia and tarsus combined and 3.4 times hind tibia; white or ivory apical part of ovipositor sheath 1.7 times as long as hind basitarsus.
Colour. Black; mandible (but dorsally basally brown) yellowish-brown; trochantelli, base of hind femur, fore and middle tibia (except ivory base) and tarsi, tegulae, sternites apically and hypopygium (except dark brown base) yellowish brown; bases of fore and middle tibiae, subbasal ring of hind tibia and hind basitarsus (except dark brown basal third and narrowly brown apex) ivory; apex of ovipositor sheath ivory; palpi, pterostigma, remainder of legs and veins dark brown; metasoma laterally orange brown; wing membrane hyaline.
Male. Similarly stout as female, but frons and vertex coarser coriaceous-rugulose; pronotal side rugulose ventrally and mesoscutum more coarsely sculptured. Third antennal segment 1.2 times as long as second segment, fourth segment 1.8 times third segment and as long as second and third segments combined, fifth segment nearly as long as fourth segment (Fig. 234); hind tibia dark brown, but ventrally largely brown except for subbasal ivory band; hind tarsus brown, but basitarsus with ivory dorsal patch and laterally mainly pale brown; apex of paramere broadly pale yellowish or ivory (Fig. 231).
Variation. Length of body of both sexes 9.5-12.2 mm; length of ovipositor sheath 3.3-3.4 times as long as hind tibia and 1.1-1.3 times as long as metasoma and ivory apex 1.6-1.8 times as long as hind basitarsus; hind tibia of female 3.8-4.1 times as long as wide.
