description: Neoneurus clypeatus (Foerster, 1863)
Ecclites clypeatus Foerster, 1863: 245. Transferred to Neoneurus by Ashmead (1900).
Elasmosoma viennense Giraud, 1871: 301. Transferred to Neoneurus by Bengtsson (1918).
Material examined. 2♂, NE China, Heilongjiang, Mudanjiang, Mudanfeng 17.VII.2011, Minlin Zheng; 2♂, NE China, Heilongjiang, Mudanjiang, Mudanfeng 17.VII.2011, Yingying Zhao.
Description. Specimen from NE China, ♂, length of fore wing 1.7 mm, body 2.7 mm.
Head. Antennomeres 16, antenna 1.1 × as long as fore wing, 0.8 × as long as body, and 1.8 × as long as head and mesosoma combined (Fig. 1). First flagellomere 1.2 × as long as second flagellomere; first and second flagellomere 3.0 and 2.6 × as long as wide, respectively; penultimate flagellomere shorter than other flagellomeres (Fig. 2). In dorsal view, eye 2.8 × as long as temple; temples slightly linearly narrowed behind eyes (Fig. 4); ocelli medium-sized, almost in right triangle, OOL: OD: POL = 5: 3: 7 (Fig. 4); frons almost flat, largely rugulose; vertex granulate (Fig. 3). Face 1.9 × wider than high, sparsely setose, granulate (Fig. 3); clypeus smooth, 3.7 × wider than high, 0.6 × as wide as face, ventral margin straight (Fig. 3); anterior tentorial pits large (Fig. 3); malar suture shallow, narrow (Fig. 3); mandibles stout, strongly twisted (Fig. 3).
Mesosoma. Length of mesosoma 1.4 × as its height; side of pronotum coriaceous-punctate (Fig. 7); propleuron largely smooth (Fig. 7); mesopleuron largely granulate; prepectal carina completely present (Fig. 7); episternal scrobe short, wide and deep (Fig. 7); precoxal sulcus deep and wide, granulate (Fig. 7); mesonotum densely setose, flat, granulate; notauli absent (Fig. 6); scutellar sulcus smooth and deep with four crenulae (Fig. 6); scutellum flat, granulate (Fig. 6); metapleuron reticulate-rugose (Fig. 5); propodeum reticulate-rugose (Figs 6–7).
Wings. Fore wing (Fig. 8): venation largely unpigmented; 1- R 1 nearly 0.4 × as long as pterostigma; vein r issued after middle of pterostigma; 1-M short, 1.2 × as long as 1-SR; cu-a oblique and longer than 1-CU1, cu-a: 1-CU1= 3: 2. Hind wing (Fig. 8): venation unpigmented, M+CU: 1-M: 1r-m = 8: 5: 6.
Legs. Fore leg typical, tibia 4.0 × as long as wide, rather enlarged apically (Fig. 9); fore tibial spur slightly curved, 0.8 × as long as basitarsus (Fig. 9). Middle leg normal, tibia 6.5 × as long as wide; middle tibial spurs slightly curved. Hind leg modified, tibia 7.1 × as long as wide, larger apically; hind tibial outer spurs 0.4 × as long as basitarsus.
Metasoma. First tergite 1.1 × longer than its maximum width, apically 2.7 × wider than its minimum width, with spiracular tubercles medially, without dorsope, largely rugose (Fig. 7); second and third tergite rugulose-rugose; first tergite with laterope, remaining segments smooth and shiny.
Colour. Mainly brown; apex of antenna, legs yellow; fore wing darkened, veins of wings yellowish brown; antenna, clypeus, mandible, metasoma yellowish brown; apex of mandible and ventral margin of clypeus reddish brown; face and mesosoma brown; vertex and propodeum black.
Biology. Parasitoid of adult worker ants of Formica rufa (Tobias, 1976).
Distribution. Eastern Palaearctic Region: China, Mongolia, Kazakhstan; Western Palaearctic Region: Austria, Czech Republic, Denmark, Finland, Germany, Hungary, Iran, ltaly, Korea, Lithuania, Moldova, Netherlands, Norway, Russia, Sweden, Ukraine, former Yugoslavia.
