This is arboreal European species known from Great Britain, France, Belgium, the Netherlands, Germany, ?Czech, ?Slovakia, Pol- and and Russia (CET). Recorded for the first time from Sweden. Note. P. nigripes belongs to a complex of four species, the females of which are characterized by the shape of ninth sternum and males by highly characteristic structure of genitalia described above. Besides P. nigripes two other species, P remmi Havelka and P globulifera Remm inhabit the Palaearctic Region; the fourth, P. canadensis Grogan & Wirth is known from the Nearctic Re- gion. P nigripes differs from other members of the complex in dark colour of legs, mainly in entirely dark tibiae. Fig. 1. Palpomyia brachi.alis, female habitus (Length bar below = I mm). Drawing: J.
