New records of Rhaphium (Dolichopodidae, Diptera) from Russia

The present study is based on examination of the collection funds of the Zoological Institute of RAS and the Department of Ecology and Systematics of Invertebrates of Voronezh State University. New data on the fauna of 29 Rhaphium species of Russia are provided. Rhaphium tuberculatum is recorded for the first time for the Russian fauna. Rhaphium patulum is recorded for the first time for Asia. The previously known data of distribution of Rhaphium species were supplemented and updated. In this paper, new records of faunal data were provided for 29 species of Rhaphium including the following species: Rhaphium albifrons, Rh. appendiculatum, Rh. brevicorne, Rh. commune, Rh. confine, Rh. crassipes, Rh. dichromum, Rh. discolor, Rh. elegantulum, Rh. fissum, Rh. johnrichardi, Rh. laticorne, Rh. latimanum, Rh. lehri, Rh. micans, Rh. monotrichum, Rh. nasutum, Rh. nigribarbatum, Rh. obscuripes, Rh. patellitarse, Rh. patulum, Rh. penicillatum, Rh. rivale, Rh. tibiale, Rh. tridactylum, Rh. tuberculatum. Rhaphium. johnrichardi, and Rh. tuberculatum are recorded for the first time after the descriptions. The previously known range of many species has been significantly expanded. New data for rare species, known from one or two regions of Russia, were obtained: Rhaphium boreale, Rh. confine, Rh. fissum, Rh. obscuripes, Rh. patulum, and Rh. tibiale. As a result, currently 71 species of the genus Rhaphium are known from Russia.
