Abstract: Periscelis (Periscelis) fugax sp. nov. is described and illustrated based on
series of specimens from Portugal and the Czech Republic. It is probably
widespread in Europe but has not been previously recognized from the closely
related and externally very similar P. (P.) winnertzii Egger, 1862. The new
species differs from P. winnertzii not only in structures of the male and female
terminalia (illustrated) but also in colour pattern of pedicel and mesonotum.
Morphology of the male and female terminalia is studied in detail in both these
species and terminology of their structures is discussed and redefined. A new
modern key to Palaearctic species of Periscelis (s. str.) species is
constructed.
Key words: Diptera, Periscelididae, Periscelis fugax sp. nov., P. winnertzii, taxonomy, key, morphology, male genitalia, female terminalia, biology, distribution
