Material examined. 1♀ 1♂ , NE China , Heilongjiang , Mohe , 23.VII.2011 , Xiaohui Dong . Description. Specimen from NE China , ♀ , length of fore wing 1.6 mm , body 2.3 mm . Head. Antennomeres 13, antenna 0.5 × as long as fore wing, 0.3 × as long as body, and 0.7 × as long as head and mesosoma combined ( Figs 10–11 ). First flagellomere 1.3 × as long as second flagellomere; first and second flagellomere 1.4 and 1.3 × as long as wide, respectively; penultimate flagellomere much shorter than other flagellomere, 0.7 × as long as wide ( Fig. 12 ). Maxillary palp with 2 segments, labial palp with 1 segment. In dorsal view, eye 2.5 × as long as temple; temples roundly narrowed behind eyes ( Fig. 13 ); ocelli medium-sized, almost in right triangle, OOL: OD: POL = 9: 5: 13 ( Fig. 13 ); frons depressed, largely punctate, rugose in front of median ocellus; vertex punctate-striate ( Fig. 14 ). Face 1.1 × wider than high, flat, sparsely setose, strigose ( Fig. 14 ); clypeus rugulose, 3.1 × wider than high, 1.1 × as wide as face, ventral margin concave medially ( Fig. 14 ); anterior tentorial pits large ( Fig. 14 ); malar suture deep, wide and very short, almost touching base of mandible ( Fig. 14 ); mandibles stout, straight, its first tooth much longer than second tooth and very acute ( Fig. 14 ). Mesosoma. Length of mesosoma 1.3 × as its height; side of pronotum coriaceous ( Fig. 16 ); propleuron punctate-rugose ( Fig. 16 ); mesopleuron dorsally rugose, ventrally largely (including precoxal sulcus) rugulose; prepectal carina completely present ( Fig. 16 ); episternal scrobe short, wide and deep ( Fig. 16 ); precoxal sulcus deep and wide ( Fig. 16 ); mesonotum densely setose, flat, coriaceous; notauli absent ( Fig. 15 ); scutellar sulcus smooth and deep, without crenulae ( Fig. 15 ); scutellum convex, smooth ( Fig. 15 ); metapleuron rugulose ( Fig. 15 ); propodeum largely rugose. Wings. Fore wing ( Fig. 18 ): venation largely unpigmented; 1- R 1 nearly as long as pterostigma; vein r issued in front of middle of pterostigma; 1-M short, 0.8 × as long as r; cu-a oblique and distinctly longer than 1-CU1, cu-a: 1-CU1= 7: 4. Hind wing ( Fig. 18 ): venation extremely reduced, without closed cell. Legs. Fore tibia 3.4 × as long as wide, rather larger apically; fore tibial spur 1.2 × as long as basitarsus. Middle leg normal, tibia 5.7 × as long as wide; middle tibial spurs straighter. Hind tibia 5.6 × as long as wide, larger apically; inner hind tibial spur slightly longer than basitarsus, acute apically ( Fig. 19 ). Metasoma. First tergite 1.2 × longer than its maximum width, apically 1.8 × wider than its minimum width, with spiracular tubercles in front of middle, without dorsope, largely rugulose ( Fig. 17 ); second and third tergites granulaterugulose; first tergite with laterope, remaining segments smooth, compressed and shiny; hypopygium broad, finely setose, setae along apical margin short, with a moderately deep emargination ( Figs 20–21 ); ovipositor very short, apically slightly curved ( Fig. 21 ); ovipositor sheath robust and short, 2.2 × as long as wide, in apical half covered with long setae, largely smooth ( Fig. 21 ). Colour. Mainly black; fore wings slightly darkened, veins light brown; mandible, fore leg, middle tarsus, hind tarsus and ovipositor yellowish brown; antenna, ventral margin of clypeus, middle and hind legs (except tarsus), ovipositor sheath brown. Male. Length of body 2.7 mm ; antenna with 13 segments; fore leg normal, tibia 4.4 × as long as wide; fore tibial outer spur 0.7 × as long as basitarsus. ( Fig. 11 ). Biology. Parasitoid of adult worker ants of Camponotus castaneus , Formica integra , F. subsericea . For details see Poinar (2004) . Distribution. East Palaearctic Region: China (new record), Mongolia , Tajikistan ; Nearctic Region: Canada , U.S.A. Remarks. The species is recorded in China for the first time. It is the widest spread species of Elasmosoma . The Chinese specimens examined in this study slight differ from original description by the hind tibial inner spur slightly longer than the hind basitarsus (the outer spur slightly shorter than basitarsus).
