The key presents all 59 species of the genus Trichocera MEIGEN which occur in Europe. Four subgenera are represented: Trichocera MEIGEN 1803 (five species), Metatrichocera DAHL 1967 (seven species), Saltrichocera KRZEMIÑSKA 2002 (35 species), and Staryia KRZEMIÑSKA & GORZKA 2016 (13 species). The type material of two species, one from North America and one from Asia, are described (Trichocera columbiana ALEXANDER, 1927 and T. arctica LUNDSTRÖM, 1915), whose identities cause some problems and whose presence in the northern regions of Europe is possible. Two new species are described, Trichocera ( Saltrichocera ) longa, n. sp., and T. (Staryia) oulankae, n. sp. Trichocera versicolor is resurrected from synonymy; T. limpidipennis is synonymized with T. regelationis. There are separate keys to males and females; species are illustrated with camera pictures of diagnostic features: genitalia, antennae, and male tarsal claws, and additionally, wings and thoraces when only one sex is known, to enable further search. The state of knowledge of the genus in Europe and in the world is discussed.

The ventral receptacle is a kind of a sperm storage shaped as an elongated pouch and positioned at the ventral side of female genitalia. It is a novelty and an alternative system to the spermathecae present in a vast majority of Diptera, and insects in general. Among the Diptera the ventral receptacle is present in the families of Brachycera Acalyptrata; the subgenus Trichocera (Staryia) is the only taxon among the entire Diptera Nematocera known to date in which the ventral receptacle was found. The subgenus comprises 13 species known from northern and central Europe. In this paper two new species of Staryia are described, one from Switzerland, and the other from Scandinavia. Additionally, a revised description of a female of T. (Metatrichocera) gigantea DAHL, 1967, is provided, based on specimens from the far eastern locality in Siberia.

Subgenus Trichocera (Saltrichocera) in Scandinavia: a new species and first records from Finland (Diptera, Trichoceridae). Acta zool. cracov., 57(1-2): 1-10. Abstract. From localities in Sweden in Finland in the vicinity of Polar Circle 14 species of the subgenus Trichocera (Saltrichocera) are recorded; all new to Finland, and 5 – to Sweden. A new species related to T. (S.) antennata, T. (S.) montium and T. (S.) thaleri is described from Finland. A female of T. (S.) michali is illustrated.
