Type material.

Holotypes of Gasteruption insidiosum , ♀ (ZISP) from Russia (South of Volgograd, Kalmuck-steppe), of Gasteruption fallaciosum ♀ (ZISP) from Belorussia (Minsk), of Gasteruption obsoletum ♀ (ZISP) from Russia (Pensa) and of Gasteruption dubiosum ♀ (ZISP) from Russia (St. Petersburg) examined by the first author.

Additional material.

Iran (Alborz, Chalous Road, Shahrestanak; id., Sarziarat; Qazvin, Zereshk Road); Turkey (60 km W of Konya, Erflatun Pinar; 50 km S of Kars, Pasli; Konya, 30 km S of Aksehir, 20 km W of Van; 15 km E of Malatya; Zelve, Nevsehir; 25 km E of Malatya, Kopeksiz; near Karabulak; 30 km E of Mansisa; Burdur, 28 km SEE of Burdur, 1350 m; id., 20 km SW of Burdur, 940 m; id., 5 km NE of Yesilova, 1060 m; Isparta, Egirdir Gölu, 5 km N of Akkecili, 920 m; 54 km W of Kayseri, Göreme; Kayseri, Göreme, 1000 m; Maras, Goksün, 1400 m; Hakkari, Hakkari, 1750 m; Van, Van, 1800 m; Adiyaman, Gölbasi, 900 m; Hakkari, Mt. Sat, SW of Yüksekova, Varegös, 1650 m; Van, Baskale, 2200 m).

Diagnosis.

Length of ovipositor sheath 2.8-3.1 (rarely up to 4.3) times as long as hind tibia, 0.8-0.9 (rarely up to 1.2) times metasoma and 0.6-0.9 times as long as body; occipital carina widely collar-shaped and area in front of carina more or less aciculate (Figs 235, 249); mandible yellowish or orange brown basally; apical pale brown part of ovipositor sheath 0.1-0.3 times as long as hind basitarsus; mesoscutum more or less crater-like punctate because of deep medium-sized punctures (Figs 237, 244); lateral lobe of mesoscutum largely coarsely punctate; apical half of hind tibia more or less reddish brown and with pale yellowish setae; stout species. Male has third antennal segment 1.3-1.5 times longer than second segment and fourth and fifth segments 1.7-1.8 and 1.6-1.7 times as long as third segment, respectively (Fig. 247).

Close to Gasteruption erythrostomum (Dahlbom) but this species has the apical half of the hind tibia black or dark brown ventrally and with brown setae (more or less reddish brown and with pale yellowish setae (Fig. 238) in Gasteruption insidiosum ), the ovipositor sheath shorter (1.7-2.6 times as long as hind tibia, 0.6-0.8 times metasoma, 1.1-1.6 times hind tibia and tarsus combined versus 2.5-3.1 times as long as hind tibia, 0.8-0.9 times metasoma and 1.7-1.9 times hind tibia and tarsus combined in Gasteruption insidiosum ), the mesoscutum of female (especially lateral lobe) mainly coriaceous with at most small superficial punctures and rather shiny antero-dorsally (punctures deep, medium-sized and more or less finely crater-like and mixed with fine punctures between punctures, rarely only coarsely punctate) and matt antero-dorsally; mesoscutum of male transversely rugulose or moderately rugose, more coarsely punctate in Gasteruption insidiosum ), the hind tibia black ventrally (usually partly reddish brown ventrally, rarely black), the occipital carina less collar-shaped and straight medio-dorsally (wide collar-shaped and more or less sinuate medio-dorsally) and the mesoscutum hardly setose (rather setose). Also similar to Gasteruption nigrescens Schletterer, 1885, but Gasteruption insidiosum has the ovipositor sheath 0.5-0.6 times as long as body and 2.6-2.9 times hind tibia (0.8-1.0 times body and 3.5-4.7 times hind tibia in Gasteruption nigrescens ), the mesoscutum more crater-like punctate, the occipital carina wide (usually narrower in Gasteruption nigrescens ) and the hind tibia wider and ventral half often partly dark brown (slenderer and black).

Distribution.

East Europe, Iran, Turkey.

Biology.

Unknown. Collected in June-July.

Notes.

The occurrence of Gasteruption erythrostomum in Iran and Turkey is questionable. The reported specimens most likely belong to the similar Gasteruption insidiosum Semenov.
