ABSTRACT. A review of 14 species of the Rhaphium caliginosum species group in the Palaearctic Region is presented, including R. makarkini Grichanov, sp.n. from Primorye. Species of the group differs from the other groups in the following combination of characters: hind coxa with a strong black lateral seta; mid coxa usually with black apical setae, often forming spine; femora and tibiae mainly yellow; frons shining blue, without pruinosity; face silvery-white or grey; antenna with band-like postpedicel and rather short arista-like stylus; thoracic notopleuron usually without black spot; cercus simple, non-lobate. A key to species of the group is provided; new records for previously known species are given from Kazakhstan, Russia and Sweden. R. appendiculatum Zetterstedt, 1849 is found in Kazakhstan for the first time, as is R. caliginosum Meigen, 1824 from Belgorod and Perm oblasts of Russia, and R. monotrichum Loew, 1850 from Buryatia and Yamalia.
