Platygaster oviventris sp. n. (Figs 47-50) Female - Length 1.0-1.1 mm. Black; antennae, tegulae and legs dark brown, ends of tibiae and segments 1-4 of all tarsi more or less lighter brown. Head from above (Fig. 47) 2.0 x as wide as long, as wide as mesosoma, rather uniformly reticulate-coriaceous; occiput medially with a few transverse wrinkles, frons smooth medially. Head in frontal view 1.3 x as wide as high; antenna (Fig. 48) with A

1 0.7 x as long as height of head, A9 1.1 x as long as wide. Mesosoma 1.2 x as long as wide, hardly higher than wide. Sides of pronotum reticulate-coriaceous, smooth along hind margin. Mesoscutum with few hairs, distinctly and uniformly reticulate-coriaceous; notauli complete but not strong; mid lobe posteriorly finely pointed but not prolonged; scuto-scutellar grooves narrow, almost bare. Mesopleuron smooth. Scutellum (Fig. 49) sculptured as mesoscutum, with very few hairs. Metapleuron with pilosity all over. Propodeal carinae very short, much transverse area between them unsculptured. Fore wing clear, hardly 0.9 x as long as body, 2.5 x as long as wide, with fine and dense microtrichia; marginal cilia at their longest 0.1 width of wing. Hind wing 5.6 x as long as wide, with two hamuli; marginal cilia 0.3 width of wing. Metasoma (Fig. 50) about as long as head and mesosoma combined, as wide as mesosoma. Tl with two distinct, converging longitudinal keels, smooth between them. T2 smooth in basal foveae, between them striated to 0.3 length of tergite. T3-T6 smooth, T3-T5 each with a medially interrupted transverse row of superficially implanted hairs. Material examined - Holotype female: Mongolia, Cojbalsan aimak, 50 km SE of Cojbalsan, 700 m, 16.VIII.

1965. Paratypes: 1 female, same data as holotype; 1 female, Bulgan aimak, 11 km W of Somon Bajannuur at lake Bajan nuur, 1000 m, 24.VII.1968. Remarks - In general body shape approaching P. leptoptera BUHL, 1999, which however differs from P. oviventris in many respects, e.g. in having less transverse head, no notauli, and more elongate wings, cf. BUHL (1999£>). Platygaster cf. pedasus WALKER, 1835 Material examined - 1 female, Archangaj aimak, 20 km N of Charchorin, 1640 m, 1 .VII. 1964; 1 female, Central aimak, about 30 km E of Somon Nalajch, 1530 m, 14.VI.1966; 1 male, Archangaj aimak, Changaj mountains, 8 km W of Somon Urdtamir, 1620 m, 21.VII. 1966; 1 female, Central aimak, 11 km S of pass Zossijn davaa, 90 km S of Ulan-Baator, 1650 m, 7.VI.1967.
