New records of Dolichopodidae (Diptera) from Khabarovsk Krai, Russia

A new material of Dolichopodidae has been recently collected from the central part of the Khabarovsk Krai and includes 38 species. Sixteen species are recorded from this territory for the first time, including Gymnopternus klowdeni (Olejníček, 2002), which is new for Russia. Twelve species are known at present only from the easternmost Palaearctic Region: Argyra flavida Negrobov, 1973, A. shamshevi Selivanova et Negrobov 2007, Dolichopus soldatovi Negrobov, Selivanova et Maslova, 2013, D. xanthopyga Stackelberg, 1930, Gymnopternus daubichensis (Stackelberg, 1933), Gymnopternus nemorum (Smirnov et Negrobov, 1977), G. rohdendorfi (Stackelberg, 1933), G. ussurianus (Stackelberg, 1933), Rhaphium curvitarsus Negrobov, Maslova et Selivanova, 2020, R. firsovi Stackelberg et Negrobov, 1976, R. flavilabre Negrobov, 1979, and Syntormon violovitshi Negrobov, 1975. This paper also provides distribution patterns for each collected species. In total, 104 species are reported from this Region that apparently makes up 50–60% of actual Dolichopodidae regional fauna.
