Dorsellum smooth. Propodeum smooth, with row of very fine fovea at base. Mesepimeron 1.6 times longer than broad, shorter than mid coxa (52:33). Hind coxa 2.6 times as long as broad with finely but distinctly raised reticulation, its hind edge strongly curved. Hind femur 4.8 times as long as broad. Spur of hind tibia 0.36 length of basitarsus. Forewing ( Fig. 6 d ) 2.26 times as long as broad; costal cell 6.2 times as long as broad, upper surface with some setae basally, beneath with one broken row in basal quarter and distal third plus a few scattered setae in the same area; basal vein with 6-7 setae; basal cell closed below; speculum open, extending beyond parastigma; M:PM:ST=60:18:5, stigma very shortly petiolate, slightly oblique. Gaster ( Fig. 6 e ) distinctly compressed; basal sternite extending beyond coxa by about one-third length of latter; hypopygium extending three quar- ters along gaster, bare except tip. Ovipositor ( Fig. 6 a ) index 3.8, slightly longer than body. Length 2.6 mm . Colour: body dark green, with metallic reflection; scapus basally yellow. Palpi testaceous. Legs with all coxae dark, concolorous with thorax, all femora and tibiae infuscate, tarsi yellow, except pretarsi black;. Wings hyaline, veins brown. Male: unknown. C o m m e n t s. One species of Torymus , T. halimi GRAHAM & GIJSWIJT , has been known as parasite of A. conglomerata on A. halimus in Canary Islands , Spain , another species, Torymus schizothecae RUSCHKA reared from galls of Steffaniella sp. on Atriplex patula L. in Austria . By this study Torymus phillyreae RUSCHKA was reared from galls of Asphondylia conglomerata on Atriplex halimus . Torymus egypticus DOöANLAR sp. new differs from the species mentioned above in having ovipositor at least slightly longer than body (ovipositor as long as metasoma plus half of mesosoma in T. halimi and T. phillyreae , and as long as gaster in T . schizothecae ); ovipositor index in T. egypticus 3.8 (in the other species index at most 2). Beside those species the new species similar to T. impar (RONDANI) and T. borealis THOMSON in having malar space 0.3-0.35 lenght of eye, mouth 2.1-2.65 malar space, ovipositor sheaths 1.1-1.25 length of body, 3.9-4.6, but it differs from both of them in having POL 2.0-2.21 OOL, OOL 1.1 OD (in the both species at most POL 1.6-1.8 times OOL, OOL at least 1.27 OD); it differs from T. impar in having head with temples slightly curved, and reared from galls of A.conglomerata on A. halimus (in T. impar head with temples distinctly curved, and Reared from galls of Rabdophaga rosaria (LOEW) (Dipt. Cecidomyiidae ) on Salix spp.). B i o l o g y. It may be a hyperparasitoid or parasitoid on Asphondylia conglomerata on Atriplex halimus and has low level of parasitism during the period from January to April. D i s t r i b u t i o n.
