Aprostocetus orithyia   is only known from Europe, develops on fly larvae ( Cecidomyiidae   and Chloropidae   ) and this sampling represents a new record for Iran. Aprostocetus orithyia   belongs to the lycidas species group ( Graham 1987). On P. australis   , the species could be a parasitoid of the aforementioned dipterous families.
