Type species: Symplecis alpicola Foerster , 1871: 119; Thomson 1888 : 1285; Schmiedeknecht 1911 : 2169. Blapticus Foerster 1869 : 171. Type species: Blapticus leucostomus Foerster , 1871: 83. Diagnosis. Inner eye orbits strongly convergent ventrally in female, slightly in male; clypeus small, weakly to more strongly separated from face by a groove; eye large; temple short; malar space very narrow with subocular sulcus; mandible small, usually not twisted; male antenna lacking tyloids. Notaulus short and deep; epicnemial carina complete; carinae of propodeum complete and strong. Fore wing with areolet present or absent, when present sessile or short petiolate, rectangular. First metasomal segment slender, with glymma lacking, its sternite fused to tergite. Second tergite coriaceous, or with longitudinal striae. Ovipositor usually short, almost straight, stout at base, slenderer in apical part, 0.4-0.9 times as long as hind tibia. Remarks. Medium sized genus with 14 recognized species distributed worldwide: 11 species are known in the Palaearctic region, six in the Nearctic region ( Dasch 1992 ), one in the Neotropical region, one in the Afrotropical region and one in the Oriental region ( Yu et al. 2012 ). Two species are reported from South Korea in this paper. This is the first record of the genus from this country. Both Korean species of Symplecis are Holarctic. There are two known host records for Symplecis , both from Diptera , Sciaroidea : Symplecis breviuscula Roman was reared from Diadocidia ferruginosa Meigen ( Diadocidiidae ) in Europe ( Roman 1923 ) and Symplecis matilei Delobel from Neoempheria ombrophila Matile et Matile ( Mycetophilidae ) in Central Africa ( Delobel and Matile 1976 ).
