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 cytochromec oxidase subunitI (COI) gene and the D2 expansion region of the 28S ribosomal gene. Morphological and molecular phylogenetic analyses largely support the morphological evidence. Eurytoma cristata Delvaresp.nov., Eurytoma saliphila Delvaresp.nov., and Eurytoma sylviae Delvaresp.nov. are described from France, Eurytoma ithma Delvaresp.nov. is described from France and Italy, and Eurytoma gatesi Delvaresp.nov. is described from North America and France. Decatomidea polygraphiAshmead, 1894 and Ipideurytoma spessivtseviBouek & Novicky, 1954 are synonymized with Eurytoma afraBoheman, 1836. Eurytoma auricomaMayr, 1878 is removed from synonymy with Eurytoma arcticaThomson, 1875 and is synonymized with Eurytoma mauraBoheman, 1836. Eurytoma eccoptogastriRatzeburg, 1844, Eurytoma flavoscapularisRatzeburg, 1844, Eurytoma flavovariaRatzeburg, 1844, and Eurytoma masii var. flavonigraRusso, 1938 are synonymized with Eurytoma morioBoheman, 1836. Eurytoma masiiRusso, 1925 and Eurytoma kemalpasensisNarendran, Tezcan & Civelek, 1995 are synonymized with Eurytoma striolataRatzeburg, 1848. Eurytoma melanoneuraWalker, 1871 and E. masii are removed from synonymy with E. morio. Lectotypes are designated for E. afra, E. auricoma, E. masii, Decatoma aloisifilippoiRusso, 1938, and E. masii var. flavonigra.(c) 2014 The Linnean Society of London
