Synopeas koreana Buhl, 2006, sp. n.

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.朝鲜柄腹姬小蜂（Synopeas koreana）新种（sp. n.） 图版45至49 雌性—体长1.0–1.2 mm。体黑色；触角第一至第六节（A1–A6）以及足呈黄色；第七至第十节（A7–A10）、各足基节、后足股节端半、后足胫节端半，以及所有跗节的末节均或多或少变暗。 头部背面观（图45）：宽为长的1.7倍，略宽于中胸；体表整体均匀且明显具网状革质纹（非横向网状）；后头脊完整但不粗壮。侧单眼直径约为侧单眼复眼距（OOL）的2倍。头部正面观：宽为高的1.1倍；触角（图46）的第一节（A1）长为头部高的0.9倍。 中胸长为宽的1.5倍，高约为宽的1.2倍。前胸背板侧面光滑，前上角具粗糙皱纹。中胸盾片疏被毛，体表网状革质纹比头部略细且均匀，无盾纵沟；中叶后缘中部具细小的无特化突起，两侧具多数长毛；盾纵沟宽阔，明显横向。中胸侧板光滑。 小盾片（图47）光滑，被毛比中胸盾片更浓密，沿中线具1条纵脊，该脊末端延伸为垂直、近乎半透明的片状突。后胸侧板全面被毛。并胸腹节脊适度高，略弯曲，略带半透明。 前翅透明，长为体长的0.8倍，长为宽的2.3倍，具适度密集的微毛，无缘毛。后翅长为宽的6.3倍；缘毛长为翅宽的0.4倍。 腹部（图48）：长为头部与中胸总长的0.8倍，宽与中胸相当，宽为高的1.4倍。第三至第五腹背板（T3–T5）的后缘以及第六腹背板（T6）的大部分区域具网状革质纹；端部背板具少量毛。 雄性—体长1.0 mm。触角（图49）的鞭节被毛极短。 检视标本：正模雌虫：朝鲜北部平安南道平壤以北50 km长兴山，1971年8月13日，S. HORVATOVICH与J. PAPP采集。副模：1头雌虫，采自朝鲜北部江原道温井郡金刚山靠近Go-song酒店区域，海拔250 m，1975年8月5日，J. PAPP与A. VOJNITS采集；1头雄虫，采自朝鲜北部白头山三池渊酒店周边林区，1977年7月18–20日，网扫草丛采集，DELY与DRASKOVITS采集。标本保存于匈牙利自然历史博物馆（HNHM）。 本种在KIEFFER（1926）的分类检索表中，可被归入S. gracilicornis KIEFFER, 1916与S. bifoveatus (KIEFFER, 1912)类群，但与S. gracilicornis的区别在于雌性第四节（A4）不那么细长，与S. bifoveatus的区别在于盾纵沟的形态。 另有8份采自三池渊周边的标本（1雌7雄），虽其小盾片具明显脊突且前翅有缘毛，但大概率与正模标本为同一物种。
