Drapetis infitialis Collin

( Figs 5C, E )

Material examined. SWEDEN. Skåne: Åbrolla, Osby (56°26′N 14°08′E), 142 m, 24–30.vii. 2016 (1 ♂); 10– 13.vii.2018 (6 ♂) ( NHMD) .

Taxonomic notes. The male terminalia are very similar to those of D. exilis Meigen , but differ as follows: right epandrial lamella ventrally with prominent arm even more expanded apically; left surstylus 1 straight, not S-curved; right cercus straight, not pointing to the left on distal part. Decisive external differences between males of D. infitialis and D. exilis are seen in the surface structure of the anterior cuticle of the mid femur (cf. Figs 5C and B ).

Distribution. Widespread in Central and Northern Europe. Distribution in Scandinavia according to Chvála (1975) is restricted to the Baltic coast of Finland, but it was added to the list of Swedish Brachycera in 2007 (https:// www.dyntaxa.se/) with records from several provinces in Central and North Sweden (http://artfakta.artdatabanken. se/). It is here recorded for the first time from South Sweden and the province of Skåne.
