گزارش جدید یک گونه از خانواده Eupelmidae (Hymenoptera: Chalcidoidea) از ایران

Eupelmidae including three subfamilies Calosotinae, Neanastatinae and Eupelminae, have more than 900 species in 51 genera worldwide. These wasps are primary or secondary parasitoids and ecto or endoparasitoids of different orders of insects. Malaise or pan traps and rearing from hosts are the best methods for collecting members of this family. So far 31 species of Eupelmidae in two subfamilies (Calosotinae and Eupelminae) and seven genera were reported from Iran. Our recent collection from West-Azarbaijan province, Urmia leads us to find an eupelmid species. It belongs to the genus Eupelmus Dalman, 1820 that includes 22 species in Iran. It was identified as Eupelmus (Macroneura) falcatus (Nikolskaya, 1952). This species is widely distributed in Europe (Austria, Bulgaria, Croatia, Czech Republic, France, Greece, Hungary, Italy, Moldova, Romania, Russia, Slovakia, Spain, Switzerland, Ukraine) and Central Asia (Kazakhstan, Kirgizia, Tadzhikistan, Uzbekistan), but it is a new record for Iranian fauna. It has been reared from the galls of various species of Tetramesa in stems of grasses (Poaceae). Most important morphological characters of this species are: frontovertex at least slightly roughened, reticulate; pronotal ridge with recumbent, undifferentiated setae; mesoscutal plate more evenly and comparatively densely setose except anteriorly and posteriorly narrowly asetose, with strong metallic luster at least posteriorly; axillae and mesoscutellum with about anterior third Λ-like angulate, with dense, lanceolate, reflective setae, mesoscutellum uniformly setose; acropleuron imbricate to slightly reticulate, with microsculptured region medially; fore wing with basal cell asetose and apical part very long and sinuously pointed, at least 4× as long as basal part; hind wing present, concealed beneath fore wing and apically reflexed and infuscate; mesotarsus without pegs but with one to three longer seta-like spines; ovipositor sheaths nearly uniformly dark brown and apparently very short because gaster extending over about basal half of third valvula. The collected wasp is deposited in the Entomological collection of the Agricultural Research and Natural Resources Center of East Azerbaijan Province.
