Abstract

We describe a new species, Eurytoma caninae (Hymenoptera, Eurytomidae) from specimens collected in Morocco, France and Iran. The species emerges from galls of Diplolepis spp. (Cynipidae) on Rosa spp. (Rosaceae). It is common and widespread in the West Palearctic Region. It is closely related but morphologically differentiated from Eurytoma rosae Nees. To substantiate our morphological observations, two genes [cytochrome oxidase subunit I (COI) and the internal transcribed spacer region 2 (ITS2)] of several individuals per population were sequenced. Both analyses clearly led to the conclusion that E. caninae and E. rosae are two well-differentiated and previously overlooked species. Morphological diagnostic characters are given to identify both species.
