Revision and phylogeny of the European species of the Eurytoma morio species group (Hymenoptera: Eurytomidae), parasitoids of bark and wood boring beetles

A revision of Eurytoma (Hymenoptera, Eurytomidae) species belonging to the morio group is proposed. Species discrimination is based on morphological and, partly, on molecular data, including the barcoding fragment of the mitochondrial cytochrome c oxidase subunit I (COI) gene and the D2 expansion region of the 28S ribosomal gene. Morphological and molecular phylogenetic analyses largely support the morphological evidence. E urytoma cristata Delvare sp. nov. , E urytoma saliphila Delvare sp. nov. , and E urytoma sylviae Delvare sp. nov. are described from France, E urytoma ithma Delvare sp. nov. is described from France and Italy, and E urytoma gatesi Delvare sp. nov. is described from North America and France. Decatomidea polygraphi Ashmead, 1894 and Ipideurytoma spessivtsevi Bou?ek & Novicky, 1954 are synonymized with Eurytoma afra Boheman, 1836. Eurytoma auricoma Mayr, 1878 is removed from synonymy with Eurytoma arctica Thomson, 1875 and is synonymized with Eurytoma maura Boheman, 1836. Eurytoma eccoptogastri Ratzeburg, 1844, Eurytoma flavoscapularis Ratzeburg, 1844, Eurytoma flavovaria Ratzeburg, 1844, and Eurytoma masii var. flavonigra Russo, 1938 are synonymized with Eurytoma morio Boheman, 1836. Eurytoma masii Russo, 1925 and Eurytoma kemalpasensis Narendran, Tezcan & Civelek, 1995 are synonymized with Eurytoma striolata Ratzeburg, 1848. Eurytoma melanoneura Walker, 1871 and E. masii are removed from synonymy with E. morio. Lectotypes are designated for E. afra, E. auricoma, E. masii, Decatoma aloisifilippoi Russo, 1938, and E. masii var. flavonigra. © 2014 The Linnean Society of London
