number of valid species could be even higher, if more material from Eastern Europe, Asia Minor, Transcaucases and Iran will be collected and studied. Some of the species from the kollari group have had a strong commercial importance in the past, as it was commented above. These species names, especially "Andricus gallaetinctoriae" caused a large confusion concerning their taxonomic status in the past. Our study showed that "Andricus gallaetinctoriae" is a nomen dubius. Another name, Andricus petioli Hartig, 1843, considered by some authors as a possible synonym of Andricus kollari, and by others as a synonym of A. testaceipes or A. trilineatus (Houard, 1909); must be considered as an uncertain species, and thus we do not included it into the kollari species-group. The most closely related species to the kollari-group are A. coriarius, A. polycerus and A. conglomerate, which were included into the A. kollari clade by Stone & Cook (1998), Cook et al. (2002), and Rokas et al. (2003). However, these three species formed a separate group, within the kollari-dade (Fig. 77). Asexual adults of A. coriarius, A. polycerus, A. conglomeratus

, A. dentimitratus (Rejtő, 1887), A. glutinosus (Giraud, 1859), A. caputmedusae (Hartig, 1843) (among some others) are also somewhat similar to the kollari-group in their size and densely pubescent body, and that made old authors to include them into the Cynips genus (authors, non Linnaeus, 1758) (Kieffer 1897-1901), and later into the Adleria Fig. 77.
