2025-08-06T02:18:00+12:00

A new material of Dolichopodidae has been recently collected in the Daursky Nature Reserve, Zabaykalsky Krai of Russia, at the international borders with China (Inner Mongolia) and Mongolia (Dornod Province), including 20 species (all species are found in the Reserve for the first time, and 16 species are new for the Krai). Six species found in the Reserve are reported only in the East Palaearctic Region: Chrysotus orientalis Negrobov et Tsurikov, Dolichopus galeatus Loew, D. kjari Stackelberg, D. negrobovi Gosseries, D. rotundipennis Loew, Gymnopternus rohdendorfi (Stackelberg). Medetera kaszabi Negrobov was known only from Mongolia by original description. Campsicnemus flaviantenna Tang, Wang et Yang is placed in synonymy with C. picticornis (Zetterstedt) (syn. nov.). In total, 43 species are reported in this region, which apparently makes up 25% of currently known Dolichopodidae regional fauna. This paper also provides a distribution pattern for each collected species and a regional checklist of species.

**New records of Dolichopodidae (Diptera) from Sakhalin, Russia, with description of a new Dolichopus species**

A new material of Dolichopodidae from Sakhalin has been recently found in the collection of the Karelian Research Centre of the Russian Academy of Sciences, Petrozavodsk, and includes 14 species. Dolichopus humalai Grichanov sp. nov., from southern part of the Island, is described and illustrated and associated with the Dolichopus acuticornis/longicornis group of species. The new species resembles in habitus D. acuticornis, differing from the latter in arista-like stylus arising before middle of dorsal side of antenna, entirely yellow scape, postpedicel wide, and hind tibia and basitarsus yellow. Dolichopus acuticornis males have arista-like stylus arising between apex and middle of dorsal side of antenna, almost entirely black scape, pointed at apex postpedicel, black at apex hind tibia and entirely black hind tarsus. Dolichopus pennatus Meigen habitation on the Island is confirmed, and Gymnopternus ussurianus (Stackelberg) is reported from Sakhalin for the first time. Now 75 long-legged fly species are known from the Island.
