Synopeas koreana sp. n.

( Figs 45–49 )

Female – Length: 1.0– 1.2 mm. Black, A1–A6 and legs yellow; A7–A10, coxae, apical half of hind femur and of hind tibia, and last segment of all tarsi more or less darkened. Head from above ( Fig. 45 ) 1.7 times as wide as long, very slightly wider than mesosoma, distinctly and uniformly reticulate-coriaceous all over (not transversely so); occipital carina complete but not strong. Lateral ocellus fully twice as long as OOL. Head in frontal view 1.1 times as wide as high; antenna ( Fig. 46 ) with A1 0.9 times as long as height of head. Mesosoma 1.5 times as long as wide, almost 1.2 times as high as wide. Sides of pronotum smooth, with rugosity in upper anterior corner. Mesoscutum sparsely hairy, uniformly and slightly finer reticulate-coriaceous than head, without notauli; hind margin medially with a tiny, unmodified prolongation, at sides with numerous long hairs; scuto-scutellar grooves wide, much transverse. Mesopleuron smooth. Scutellum ( Fig. 47 ) smooth but with denser hairs than mesoscutum, along middle with a keel which ends in a vertical, hardly semitransparent lamella. Metapleuron with pilosity all over. Propodeal carinae moderately high, slightly curved, faintly semitransparent. Fore wing clear, 0.8 times as long as body, 2.3 times as long as wide, with moderately dense microtrichia, without marginal cilia. Hind wing 6.3 times as long as wide; marginal cilia 0.4 width of wing. Mesosoma ( Fig. 48 ) 0.8 times as long as head and mesosoma combined, as wide as mesosoma, 1.4 times as wide as high. Hind margin of T3–T5, and most of T6, reticulate-coriaceous; apical tergites with a few hairs.

Male – Length: 1.0 mm. Antenna ( Fig. 49 ) with very short flagellar pubescence.

Material examined: Holotype female: North Korea, South Pyongan, Chang-lyong san, 50 km N of Pyongyan, 13.VIII.1971. S. HORVATOVICH & J. PAPP leg. Paratypes: 1 female, North Korea, Gang-von, district On-dzong, Kum-gang san, near Hotel Go-song , 250 m, 5.VIII.1975, J. PAPP & A. VOJNITS leg.; 1 male, North Korea, Mt. Pektusan , environs Sam-zi-yan hotel, wood, 18–20.VII.1977, netting in grasses. DELY & DRASKOVITS leg. Preserved in HNHM.

Runs to S. gracilicornis KIEFFER, 1916 and S. bifoveatus (KIEFFER, 1912) in KIEFFER’ s (1926) key, but differs from S. gracilicornis in having less elongate female A4, and from S. bifoveatus in shape of scuto-scutellar grooves.

Eight further specimens from the environs of Sam-zi-yan (1 female, 7 males) are possibly conspecific with types though they have distinct scutellar spine and fore wings with marginal cilia.
