we have examined a large number of A. hispanicus specimens which emerged on the same date from galls collected from the same oak tree in Martorell (Barcelona, Spain). We found that the number of antennái flagellomeres varied between 11 and 12 (in some specimens the suture between Fl 1 and F12 was absent, incomplete or very indistinct). There is also a strong variability in colouration (from yellow to dark brown) and density of pubescence. Taxonomic comments - It is possible that Diplolepis gallaetinctoriae described by Olivier (1791), belongs to this species (see also Taxonomic comments on A. kollari). Stone et al. (2001) showed through a genetic analysis, that the Iberian and Southern France populations of A. kollari 'sensu lato' differ from other European populations of this species. These results confirm the biological data of Pujade-Villar (1992), who found a different sexual form for the Iberian populations of "A. kollari". The first author who gave a different name for A. kollari collected in the Western range of A. kollari 'sensu lato' was Hartig (1856). He described this species as "Cynips hispanica" from the material collected in Sierra de Ronda (Southern Spain) (Pujade-Villar & Bellido 2000). The original description of this species is identical to A. kollari of the Eastern range, but both genetic analysis (Stone et al. 2001) and biological results (Pujade-Villar, Folliot & Bellido 2003 in print) support that both forms represent two sibling species, and, thus the valid name for the Western range of A. kollari 'sensu lato' (Iberian Peninsula, Southern France and North Africa) is A. hispanicus (Hartig, 1856) (Pujade-Villar, Folliot & Bellido 2003). While the asexual forms of A. hispanicus and A. kollari cannot be distinguished morphologically, sexual forms could be separated (Pujade-Villar, Folliot & Bellido 2003). Andricus kollari var. minor (Kieffer, 1900) was recently synonymized to A. kollari (Melika et al. 2000). This variety (or subspecies) was originally described from Spain and Portugal (Kieffer 1897-1901), within the range of A. hispanicus distribution. So, Andricus kollari var. minor must be considered as a new synonym of A. hispanicus. Distribution - Iberian Peninsula, Southern France and probably North Africa. Biology - Asexual form associated with Quercus canariensis, Q. faginea, Q. petraea, Q. pubescens, Q. pyrenaica and Q. robur, while the sexual developing (Andricus mayeti Kieffer, 1896 = niger Tavares, 1902) on Q. suber (unlike its sibling species, A. kollari, the sexual form of which associated with Q. cerris only) (Pujade-Villar, Folliot & Bellido 2003). Adults emerge in August-September, although some adults retard their emerging until June of the next year.
