A new species of Chamaemyiidae from Turkey, Parochthiphila (Euestelia) argentiseta is described. Parochthiphila inconstans (Becker, 1903) is assigned to the subgenus Parochthiphila Czerny, 1904 after examination of the types. New records of 25 species are given from several countries around the Mediterranean and from Oman thus extending our previously scant knowledge of the distribution of these species of flies particularly in the Mediterranean.
