Platygaster draskovitsi sp. n.

( Figs 16–19 )

Female – Length: 1.2 mm. Blackish, antennae almost uniformly dark brown (basal half slightly lighter); legs brown; trochanters, boths ends of tibiae, and segments 1–4 of all tarsi more yellowish. Head in dorsal view ( Fig. 16 ) 2.0 times as wide as long, fully 1.2 times as wide as mesosoma; occiput posteriorly smooth with strongly transverse striation which is much oblique laterally, occiput in anterior third with denser, less curved striae, almost margined between posterior and anterior part; vertex weakly reticulate-coriaceous with fine transverse wrinkles; frons finely fan-like reticulate-striate. OOL and LOL about equal. Head in frontal view 1.25 times as wide as high; antenna ( Fig. 17 ) with A1 0.8 times as long as height of head, A9 as long as wide. Mesosoma 1.4 times as long as wide, 1.1 times as high as wide. Sides of pronotum finely longitudinally reticulate-coriaceous, smooth along hind margin. Mesoscutum with few hairs, finely reticulate-coriaceous; posterior half of mid lobe and most of lateral lobes smooth; notauli missing in anterior 0.25; mid lobe distinctly and broadly prolonged over anterior part of scutellum; scuto-scutellar grooves with dense, whitish hairs. Mesopleuron smooth. Scutellum ( Fig. 18 ) almost smooth, densely hairy especially laterally. Metapleuron with pilosity all over. Propodeal carinae short, widely separated, area between them smooth and shiny. Fore wing almost clear, 0.75 times as long as body, 2.1 times as long as wide, with fine and moderately dense microtrichia; marginal cilia short. Hind wing 5.0 times as long as wide, with two hamuli; marginal cilia 0.25 width of wing. Metasoma ( Fig. 19 ) nearly as long as head and mesosoma combined, slightly narrower than mesosoma. T1 evenly crenulated. T2 striated in basal foveae to slightly more than half of length, medially hardly striated. T3–T6 smooth; T3–T5 each with a complete (sometimes irregular) transverse row of deeply implanted hairs, T6 with more scattered such hairs.

Material examined: Holotype female: North Korea, Mt. Pektusan , environs Sam-zi-yan Hotel, wood, 18–20.VII.1977, netting in grasses. Paratype: 1 female, North Korea, Sa Gam, 30–40 km N of Pyongyan, water-basin, wood, 5.VII.1977, netting in grasses. Both DELY and DRASKOVITS leg. Preserved in HNHM .

Named after one of the collectors. Similar to P. punctiventris BUHL, 2006 , but differs from this species most obviously in having differently structured posterior part of mid lobe of mesoscutum; it differs also from P. punctiventris e.g. in having less densely but sharper striated occiput on a smoother background, longer notauli, broader wings, and T2 slightly differently striated, cf. BUHL (in press).
