【Abstract】 In the present paper a new genus and a new species of Ptemalidae are described from-Beijing. All type specimens are deposited in the Institute of Zoology, Academia Sinica.Neocoruna gen. nov.Type species: Neocoruna sinica sp. nov.The new genus belongs to Pteromalidae, Pteromalinae and is allied to Coruna Walker,. 1933, both which and Neocoruna have in common the first tergite narrow and elongated; pro-notal collar sharply margined, fore wing with marginal vein thickened throughout; no auli, complete or nearly complete and deep; petiole small and smobth. From Coruna the new genus differs by the occiput sharply margined; anterior margin of clypeus emarginate medially; genac on the underside with a broad hollow, which sharply angulated in the post-ventral; fore wing not with distinct speculum; first tergite narrowly elongated.Neocoruna sinica sp. nov.Head in dorsal view 2.1-2.2 times as broad as long; temple 1/3 times as long as eye; OOL 1.4-2 times as long as POL. Head in frontal view (fig. 1) 1.5-1.7 times as broad as high; distance between the eyes 2.5-3.5 times as long as the high of the eye; face with denser white haires. Head in profile (fig. 2). Antennae inserted at uppersurface of face; scape thickened towards the end, about as lon as the pedicellus, anelli and first two funicle combined; combined length of pedicel and flagellum distinctly shorter than width of head.Mesoscutum 2.3-2.4 times as broad as long. Scutellum in the front with deep transverse -sunken which bears 5-8 longitudinal ridges. Propodeum not full 3/4 times as long as scutel-lum medially. Dorsal surface of the coxa of hind leg smooth.Petiole small, smooth; first tergite narrowly elongated or thickened towords the end, the other tergitcs capitate.Male: Allied to female; the anterior margin of clypeus slightly emargsnated medially. Allotypp with fore wing no maculate.Holotypc ♀, allotypc ♂, paratypes 7♀♀, 13 Ⅸ. 1984. paratype 1♀, 25. FX. 1984.
