Abstract:

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.
