species described herein as new was also found on an unidentified oak species belonging to the Cerris section. We follow the current terminology of morphological structures (EADY & QUINLAN 1963, GIBSON 1985, RONQUIST & NORDLANDER 1989, MENKE 1993, FERGUSSON 1995). Abbreviations for forewing venation follow RONQUIST & NORDLANDER (1989). Measurements and abbreviations used here include: Fl-Fl 2, 1st and subsequent flagellomeres; POL (post-ocellar distance) is the distance between the inner margins of the posterior ocelli; OOL (ocellar-ocular distance) is the distance from the outer edge of a posterior ocellus to the inner margin of the compound eye; LOL, the distance between lateral and frontal ocellus. Width of radial cell measured along 2r. Pictures of some structures of adult wasps were made by digital camera, after that were worked up in AdobePhotoshop 6.0, print out and then linear drawings were made from them. A key to the identification of the Western Palaearctic Neuroterus species was given earlier (MELIKA et al. 1999) and, thus in this paper we are giving only the diagnostic characters of the newly described species, Neuroterus gyulaigaraiae sp. n., on the basis of which it can be easily identified and distinguished from all other known Western Palaearctic Neuroterus species. Neuroterus gyulaigaraiae sp. n. (Figs 1-10) Type material- Holotype: asexual female labelled as follows: "Syria, Al Ladhiqiyah Province, Jabal an Nusayriyah, Slinfah, on Quercus sp. (Cerris section), 2004.X.

08, leg. P. Gyulai & A. Garai", red label "HOLOTYPE. Female. Neuroterus gyulaigaraiae MELIKA 2005, desig. G. Melika 2005". Paratypes: three females with the same label as the holotype. The holotype female and galls are deposited in the Hungarian Natural History Museum, Budapest, Hungary (HNHM), 3 female paratypes and galls - in the collection of the Systematic Parasitoid Laboratory, Kőszeg, Hungary. Gall material - 12 galls in 3 clusters collected at the same site as the type material and which from the adult wasps were cut out. Description - 1.8-2.0 mm. Body, black, glabrous, antennae black, legs very dark brown to black, tips of mandibles dark brown. Forewing uniformly hyaline, without smoky spots. Head coriaceous, with sparse white setae, which are more dense on frons, 2.6 times as broad as long from above (Fig. 1 ), 1.3-1.4 times as broad as high in front view (Fig. 2). Gena alutaceous to delicately coriaceous, slightly broadened behind eye, 0.5 times as broad as cross diameter of eye; malar space without sulcus, delicately coriaceous, 0.3-0.4 times as long as height of eye. POL very slightly longer or equal to OOL, 1.6 times as long as LOL; diameter of lateral ocellus nearly 4.0 times as short as LOL; frons alutaceous, glabrous, with impression under the frontal ocellus. Transfacial distance 1.3-1.4 times as broad as eye height; diameter of torulus slightly larger than distance between them and slightly larger than distance between torulus and inner margin of eye; lower face coriaceous, with central elevated area, going from toruli to the base of clypeus. Clypeus rectangular, delicately
