FIRST PORTUGUESE RECORD OF THE GENUS ATRICHOPS VERRALL (DIPTERA: ATHERICIDAE) Rui Andrade Rua Calouste Gulbenkian 237 4H3, Porto, Portugal – [email protected] Abstract: The dipteran family Athericidae is, in Portugal, insufficiently known with only one species recorded to date. In this paper, the species Atrichops crassipes (Meigen, 1820) is recorded for the first time in Portugal increasing the number of species of this family in the country from one to two. Key words: Diptera, Athericidae, Atrichops crassipes, new record, distribution, Portugal. Primera cita portuguesa del género Atrichops Verrall (Diptera: Athericidae).
