FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK Volume 64 2003 pp. 121-170. Cynipid inquiline wasps of Hungary, with taxonomic notes on the Western Palaearctic fauna (Hymenoptera: Cynipidae, Cynipinae, Synergini) I PUJADE-VILLAR, G. MELIKA, P. ROS-FARRÉ, Z. ÁCS and GY. CSÓKA Abstract: Wc list 29 species of cynipid inquilines (Hymenoptera: Cynipidae, Cynipinae, Synergini) for the Hungarian fauna and 38 species for the Western Palaearctic region. Fourteen cynipid inquiline names with uncertain status are given. Two new names, Synergus samnalievae Pujade-Villar et Melika and S. vassilevaensis Pujade-Villar et Melika and four names with a new status, Synergus radiatus Mayr, 1872, S. pallipes Hartig, 1840, S. tibialis Hartig, 1840, and Synophrus pilulae Giraud in Houard, 1911 are proposed; one Periclistus and 29 Synergus species are newly synonymized. Lectotypes for 22 inquiline species are designated. Host cynipid gall-inducing wasps, synonymy, distribution and biological data for each species are given. For 17 species of cynipid inquilines 45 new cynipid gall wasp hosts are given, which are not mentioned yet in the literature and recorded for the first time from the Hungarian fauna. Identification keys for species distributed in Hungary are also given. Key words: Cynipidae, Synergini, Quercus, inquiline, gall inducing wasp, host association, taxonomy INTRODUCTION Besides distinct morphological features of the Synergini tribe (Hymenoptera: Cynipidae), its biological peculiarities are very important in the separation of this group of cynipid wasps. Inquiline gall wasps are known predominantly from the galls of oak gall wasps (e.g. Askew 1984, Burks 1979, Nieves Aldrey 2001/?, Nieves Aldrey & Pujade Villar 1985, 1986, Pujade Villar & Nieves Aldrey 1990, 1993, Schönrogge et al. 1994a, b, 1996a, b, Washburn & Cornell 1981) and rose gall wasps (Askew 1980, 1984, Brooks & Shorthouse 1997, Judd 1959, Nordländer 1973, Shorthouse 1973, Shorthouse & Brooks 1998, Stifle 1984). Sporadicly some inquiline species have been cited in midge galls (Diptera: Cecidomyiidae) collected from Quercus cerris. Also a North American species, Ceroptres inermis (Walsh, 1864) was originally described as an inquiline in galls of Cincticornia
