Blood-sucking flies of the genus Ornithomya Latreille, 1802 (Diptera: Hippoboscidae) inhabit mainly the middle latitudes of the Old World. They are parasites of birds, especially birds of prey. Some small non-predatory birds, which are unable to effectively clean their plumage and catch parasites in it, are also attractive hosts for these parasites. The fauna of the genus Ornithomya is quite extensive. It includes at least 31 species, 8 of which were found in Russia. Despite the constant interest of researchers in this group, the fauna of this genus in Russia remains insufficiently studied. Scientists from the Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences (IEE RAS) described a new species of the genus Ornithomya – O. nazarovi Yatsuk, Matyukhin et Nartshuk, sp. n. – from Simushir Island (Sakhalin Oblast, Russia). The new species differs from other species of the genus Ornithomya inhabiting Russia and Japan in the length of the head and thorax, the length of the wings, the number of bristles on the scutellum, the arrangement of microtrichia on the wings, and the coloration of the dorsal and ventral sides of the thorax.
