Buhl, P. N.: Platygastridae (Hymenoptera) from Mongolia

Platygaster betulae (KlEFFER, 1916) Material examined - 4 females, 1 male, Central aimak, Tosgoni ovoo, 6-10 km N of Ulan­Baator, 1700 m, 4-8. VI. 1968. Platygaster betularia KlEFFER, 1916 Material examined - 2 females, Central aimak, Ulan-Baator, Nucht in Bogdo ul, 1650 m, 3.VI. 1967; 9 females, Central aimak, Tosgoni ovoo, 6-10 km from Ulan-Baator, 1700 m, 4-8.VI. 1968; 2 females, Central aimak, Bugijn az achuj in Bogdo ul, 36 km SW of Ulan-Baator, 1650 m, 10.VI.1968. Platygaster brevipetiolata sp. n. (Figs 25-28) Female - Length 1.2 mm. Shiny black, antennae hardly lighter; legs dark brown, both ends of tibiae slightly lighter. Head from above (Fig. 25) 2.0 x as wide as long, slightly wider than mesosoma; occiput rather strongly transversely striated; vertex moderately reticulate-coriaceous; frons reticulate-coriaceous in upper half, in lower half becoming finely fan-like striated, medially smooth. OOL: LOL = 4:3. Head in frontal view 1.3 x as wide as high. Antenna (Fig. 26) with Al 0.75 x as long as height of head; A9 as long as wide. Mesosoma hardly 1.3 x as long as wide, hardly higher than wide. Sides of pronotum longitudinally reticulate-coriaceous, smooth along upper and hind mar­gins. Mesoscutum almost entirely smooth, with a few hairs, with very weak indications of notauli, these ending in weak rugosity at anterior margin; mid lobe posteriorly slightly and bluntly prolonged to base of scutellum; scuto-scutellar grooves wide, each with 8-9 long hairs. Mesopleuron smooth. Scutellum (Fig. 27) smooth, towards sides with numerous slightly raised hair-implantations. Metapleuron finely sculptured, with sparse pilosity. Propodeal carinae very short, well separated, area between them smooth. Fore wing almost as long as entire body, 2.2 x as long as wide, almost clear, with dense microtrichia; marginal cilia short. Hind wing 5.3 x as long as wide, with two hamuli; marginal cilia 0.2 width of wing. Metasoma (Fig. 28) 1.1 x as long as mesosoma, about as wide as this. Tl Finely crenulated, with two slightly stronger carinae. T2 striated in basal foveae to hardly half of length, medially slightly shorter. T3-T6 smooth; T3-T4 with moderately deeply im­planted hairs laterally, T5 with a complete transverse row of such hairs, T6 with a few such hairs. Material examined - Holotype female: Mongolia, Central aimak, Ulan-Baator, Nucht in Bogdo ul, 1650 m, 3.VI.1967. Remarks - In many ways similar to P. etsuhoae BUHL, 1999 from Spain, but this species differs from P. brevipetiolata e.g. in having finer and weaker sculp­tured head, less smooth mesoscutum and shorter notauli, cf. also BUHL (1999/?).
