Аннотация

Analysis of the latitudinal component of the Dolichopodidae distributions revealed the prevalence of the temperate group in the Yakutian fauna (74 species, or 51%). Analysis of their ranges classified according to the longitudinal extension showed the prevalence of widespread species (89, or 61.4%), in particular those with Holarctic ranges (28 species, or 19.3%). The Yakutian dolichopodid fauna is mainly derived from the Holarctic, Trans-Eurasian, Euro-Siberian, and Far Eastern faunas with inclusion of some Euro-Siberian-Central Palaearctic species. There is also a considerable fraction of East Siberian species.
