Resum


About those Megastigmus Dalman (Hymenoptera: Chalcidoidea, Torymidae) detected in
Catalonia from the Cynipid Galls collection produced on Rosa and Quercus.

(Fabr.) and M. Stigmatizans (Fabr.), the later was found for the first time in Catalonia. The third one, M. Aculeatus (Swederus), is phytophaga, and is cited for the first time in the Iberian Peninsula. At the
same time information is given about their biology and new discriminatory characteristics in order to differenciate associated cynipo species mentioned in this study.
