New records of Dolichopodidae (Diptera) from Primorsky Territory, Russia

Abstract

A collection of long-legged flies was studied in the Laboratory of Entomology of the Federal Research Centre for Biodiversity of Terrestrial Biota of East Asia, Vladivostok. A new material was identified for the first time, collected mainly by the researchers of this laboratory in the Primorsky Territory since 1970s, as well as by Igor Ya. Grichanov during his visit to Vladivostok in 2021. Unidentified material from some other scientific institutions is also included in the list. In total, new records are given for 73 species of long-legged flies. Hercostomus rohdendorfi Stackelberg, 1933 is transferred to the genus Gymnopternus (comb.n.). Mesorhaga janata Negrobov, 1984 is placed in synonymy with Amblypsilopus pilosus (Negrobov, 1979) (syn.n.). Dolichophorus immaculatus, Dolichopus henanus, D. kumazawai, Hercostomus beijingensis, Rhaphium dorsiseta, and R. mediocre are found for the first time in Russia. Chrysotus caerulescens, Hydrophorus albiceps, Rhaphium fascipes and Syntormon violovitshi are reported from Primorye for the first time. The finding of Dolichopus griseifacies is the first reliable record from Primorye. In total, 215 species from 31 genera of Dolichopodidae are known in the regional fauna.
