The Palaearctic species of <i>Eurytoma</i> (Hymenoptera: Eurytomidae) developing in stone fruits (Rosaceae: Prunoideae)

AbstractSpecies of the chalcidoid genus Eurytoma associated with stone fruits are studied for the Palaearctic region. The eight species known to have such an association are: E. amygdali Enderlein, E. maslovskii Nikol'skaya, E. padi Veresh-chagin, E. samsonowi Vasiljev, E. schreineri Schreiner, E. turkestanica sp. n., E. paramygdali sp. n. and E. armenica sp. n. The first six species are phytophagous, developing in the stones, and the last two are entomophytophages, starting their development as parasitoids of a phytophagous species and completing development feeding on plant tissue. Four species, E. amygdali, E. schreineri, E. samsonowi, and E. maslovskii are of economic importance. Information is given on the economic importance, biology, distribution and taxonomy of these species, and includes several new records for hosts and distribution. A key is given to distinguish the species.</jats:p

Review of pistaciae species group of the genus Eurytoma (Hymenoptera, Chalcidoidea, Eurytomidae) with description of one new species from arid regions of Uzbekistan

The new species, Eurytoma samarkandae sp.n., is described from arid regions near Samarkand (Uzbekistan). The new species belongs to pistaciae species group and it is close to E. trjapitzinі Zerova et Klymenko, 2018. E. samarkandae sp.n. differs from E. trjapitzinі in upturned metasoma (elongate in E. trjapitzini), longer funicular segments of female, and yellow antenna, mesosoma and legs. Material was reared from small galls of Cynipidae (Hymenoptera) in flower heads of knapweed Rhaponticum sp. (Asteraceae). Review of pistaciae species group is given, as well as the key to all species of this group.</jats:p

A new species of Dolichopus Latreille, 1796 (Diptera: Dolichopodidae) from Japan

The new species from Japan Dolichopus kumazawai Maslova, Negrobov et Fursov, sp. n. is described. The species is close to Dolichopus vaillanti Parent, 1927 and can be distinguished from latter by wings without stigma, postpedicel 1.7 times greater than its width, hind basitarsus mostly yellow

The first record of Eurytoma сoleopterae Zerova, 1978 (Hymenoptera: Eurytomidae) as larval parasitoid of weevils and jewel beetles (Coleoptera: Curculionidae, Buprestidae) in Turkey and Turkmenistan

The parasitic chalcid wasp Eurytoma coleopterae Zerova, 1978 (Hymenoptera: Eurytomidae) is re-described and illustrated. For the first time parasitoid E. coleopterae is reared from the larvae of weevil Metapion sp. (Coleoptera: Curculionidae), developing in seeds of Ruta sp. (Rutaceae) in Turkey. Also for the first time chalcid wasp E. coleopterae was reared from larvae of jewel beetle Meliboeus cyaneus Kiasw. (Coleoptera: Buprestidae), developing in stems of Cousinia polycephala Rupr. (Asteraceae) in Turkmenistan. Re-description of type material, a new data on the distribution, biology, host–parasitoid and host–plant trophical associations are given. Material is deposited at the collection of I.I. Schmalhausen Institute of Zoology of National Academy of Sciences of Ukraine (Kyiv, Ukraine).</jats:p
