broadened behind eye, broader than cross diameter of eye, measuring along transfacial line; malar space without sulcus, 2.2-2.4 times shorter than eye height (Fig. 1); POD 1.4 times longer than OOD; entire head finely coriaceous, with dense short white setae; occiput rounded, separated from face with deep suture, darker than rest of head. Antenna 14-segmented, darker than rest of body, especially from above; Fl longest antennái segment, subsequent flagellomeres progressively shorter, F12 longer than Fll (Fig. 2). Mesosoma higher than long, concave dorsoventrally; scutum slightly longer than broad in dorsal view, finely and indistinctly coriaceous, uniformly covered with white dense setae; notauli complete and deep, median dorsal line weak, very short and shallow, hardly traceable; anterior parallel lines distinct in anterior 1/3, parapsidal lines distinct, deep (Fig. 3) Scutellum rounded, as long as broad in dorsal view, finely coriaceous like scutum; scutellar foveae black, large, deep, with shiny bottom; distinct carina separated them (Fig. 3). Sides of pronotum and mesopleuron uniformly finely coriaceous. Fore wing nearly twice as long as body, pubescent, with short cilia on margin; radial cell 4.4-4.5 times longer than broad; veins dark brown, strong; areolet small triangular, closed. Tarsal claw with acute basal lobe; hind tibia with strong and dense setae. Central portion of propodeum smooth, shiny, without setae, limited by nearly parallel lateral longitudinal carinae, which are bent outward posteriorly (Fig. 4); propodeum laterally densely pubescent. Metasoma longer than mesosoma and head together, as high as long; terga 2 with dense pubescence at the base; subsequent terga with white dense setae at the posterior 1/3 only (Fig. 5). Ventral spine of hypopygium short, slender, with few long sparse setae; prominent part only 3.0 times longer than broad (Fig. 5). Length 4.0-4.6 mm. Type material — Holotype female: Turkey, 75 km S of Trabzon, E97 hw, nr. Kalkanli (40°37' N, 39°21' E), Pontic Mt. (Kalkanli Daglari). G. Stone, 25.9.1997., 2 female paratypes: Turkey, 75 km S of Trabzon, E97 hw, nr. Kalkanli (40°37' N, 39°21' E), Pontic Mts (Kalkanli Daglari). G. Stone, 25.9.1997. Holotype and galls in The Natural History Museum (British Museum) (NHML), 2 female paratypes and galls in G. Melika private collection. Etymology — The species is named in honour of Dr. R. R. Askew, one of the world's foremost authorities on cynipid biology. Diagnosis — Females of Andricus askewi and three other species in the genus A. polycerus (Giraud, 1859), A. coriarius (Hartig, 1843) and A. conglomerates (Giraud, 1859)) form a group of morphologically very similar species whose close relationship is also supported by DNA sequence data (Stone & Cook 1998). This species group can be separated from other Andricus species groups by the following diagnostic characters: the scutum without punctures, or at most with punctures very sparse, weak and indistinct and obscured by other sculpturing, coriaceous or rugose; the prominent part of the ventral spine of the hypopygium not more than 3-5 times longer than broad. Andricus askewi and A. polycerus differ from the two other species in the group by the gena, which are broader than cross diameter of eye, measuring along the transfacial line; the metasoma black only dorsally, brown laterally, while in A. coriarius and A. conglomerates the gena equal or slightly narrower than the cross diameter of eye, measuring along the transfacial line; the metasoma dark brown to black. In A. askewi only the posterior 1/3 of the 3rd and subsequent terga are pubescent, while in A. polycerus the whole metasoma is uniformly and densely pubescent. Gall structure and location — Irregular, globular gall on terminal or lateral buds close to the shoot tip, reaching 15 mm in greatest diameter. The gall surface is weakly shiny and smooth, with slight bumps and pits over the surface. Although superficially similar
