The paper presents a critical review of the Dolichopodidae family in the Astrakhan State Nature Biosphere Reserve (Russia). In total, 23 species from the Dolichopodidae family were indicated for this Protected Area. Four of these species have been recorded for the first time for both Europe and Russia: Asyndetus albipalpus, Asyndetus chaetifemoratus, Chrysotus dorli, Hercostomus rubroviridissimus. In addition, Dolichopus jaxarticus and Sciapus subvicinus are new species for Russia. Twenty species (Asyndetus albipalpus, Asyndetus chaetifemoratus, Asyndetus latifrons, Campsicnemus filipes, Campsicnemus simplicissimus, Chrysotus cilipes, Chrysotus dorli, Dolichopus calinotus, Dolichopus cilifemoratus, Dolichopus latilimbatus, Dolichopus jaxarticus, Hercostomus convergens, Hercostomus rubroviridissimus, Medetera diadema, Medetera plumbella, Nematoproctus longifilus, Poecilobothrus bigoti, Rhaphium penicillatum, Sciapus longulus, Sciapus subvicinus) are firstly recorded for the Astrakhan region. To date, 34 Dolichopodidae species are known in the Astrakhan region. However, further studies of the Dolichopodidae fauna in Protected Areas are needed for a more comprehensive knowledge on this Diptera family in Russia and in Eurasia as a whole.

Eight species of Rhaphium Mg. are recorded from the southern tundra of the Taimyr Peninsula (Russia), including the description of a new species, Rhaphium borisovi Negrobov, Barkalov & Selivanova sp. nov. The new species is similar to Rhaphium gruniniani Negrobov and differs from it by yellow fore coxa, equal length of hind tarsomeres 1–2 and broader inner lobe of cercus. The female of Rhaphium beringiense Negrobov & Vockeroth is described. A key to Siberian species (exclusive of Far East species) of the genus Rhaphium is presented and morphological characters of all species are illustrated.

Приводится дифференциальный диагноз между Dolichopus subpennatus и Dolichopus pennatus.  Морфология гипопигия Dolichopus pennatus и Dolichopus subpennatus изучена впервые. Выделяются новые признаки по строению вентральных метаэпистерн, метанотума и морфологии гипопигия. Форма 3-го членика усиков не может быть использована для различения видов, ввиду внутривидовой изменчивости. Приводятся данные по фауне Dolichopus pennatus и Dolichopus subpennatus. Dolichopus pennatus впервые указывается Архангельской и Свердловской областей. Dolichopus subpennatus впервые указывается для Литвы, Молдавии, Украины, Ленинградской, Воронежской, Курской и Пермской областей РФ, а также для Алтая.

Th e fauna of the family Dolichopodidae of Japan is not fully studied until now, despite that currently more than 120 species are known from this area. While in the view of its boundary location between the Oriental and Palaearctic Regions the fauna of this area consists of about 300 species of the family Dolichopodidae.By the present time only seven species of the genus Dolichopus Latreille were recorded from Japan: Dolichopus crassicosta
