08, leg. M. Tavakoli", red label "Holotype. Female. Andricus stonei MELIKA, Tavakoli et Sadeghi. Desig. G. Melika 2005". The holotype female is deposited in the Hungarian Natural History Museum (HNHM), Budapest. Paratypes: 91 paratype females are designated with the same labels as the holotype: 5 paratype females and galls arc deposited in HNHM, Budapest, 10 paratype females and galls in the museum of Research Institute of Forests and Rangelands, Tehran, Iran and 76 paratype females in the collection of the Systematic Parasitoid Laboratory, Kőszeg, Hungary. Material examined - Another 122 asexual females reared from galls collected at the same locality as the type material, and also from Ghelaie, Lorestan Province, all on Q. infectoria. Gall material - 26 galls from the same locality and with the same labels as the type material. The type adult wasps were reared from these galls. Galls from Ghelaie, Lorestan Province (collected by M. TAVAKOLI) were also examined. Description - Asexual female. 4.1-5.8 mm.

Transfacial distance 1.5-1.6 times as broad as height of eye and 1.8-1.9 times as long as height of lower face (distance between antennái rim and ventral margin of clypeus); diameter of antennái torulus 1.9-2.0 times as long as distance between them and nearly equal to the distance between torulus and inner margin of eye; lower face with very delicate coriaceous sculpture, with indistinct delicate striae, the median elevated area with distinct deep punctures. Clypeus rectangular, with delicate transverse striae, with distinct deep anterior tentorial pits, with distinct epistomal sulcus and clypeo-pleurostomal line, ventral margin slightly emarginated (Fig. 1). Vertex and occiput delicately coriaceous. Postocciput around occipital foramen impressed, dull coriaceous; posterior tentorial pits deep, shiny, smooth, elongated; gula nearly as broad as heigh, lower part narrowed down to hypostomal carina, which is strong, emarginated (Fig. 3). Labial palp 3-segmented, maxillar palp 4-segmented (Figs 5-6). Antenna 14-segmented; slightly longer than mesosoma; pedicel 2.0-2.2 times as long as broad; Fl 1.3 times as long as F2,

1.8 times as long as pedicel; F3=F4; F6-F1

1 nearly equal in length, subsequent flagellomeres only very slightly shorter than the previous; Fl 2 3.0 times as long as broad; the ratio of scape, pedicel and F1-F12 as foHows: 1.1:0.57:1.0:0.8:0.7:0.7:0.7:0.5:0.5: 0.4:0.4:0.39:0.39:0.5.
