Remarks

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.

Main morphological characters: body generally metallic with yellowish tibiae and tarsi ( Fig. 6A ), antenna with scape as long as the eye, reaching above the level of vertex; funicle very long and slender, 3-segmented, F1–F2 3.05 ×, F3 about 2.6× as long as broad ( Fig. 6B ); clava with a relatively shorter and less conspicuous, straight terminal spine. Mid lobe of mesoscutum strongly reticulate ( Fig. 6F ), areoles of reticulation about 3–4× as long as broad, with a median line, and a single row of adnotaular setae on each side. Fore wing apically ciliate, submarginal vein with 2 dorsal setae, speculum absent. Spur of mid tibia longer than half the length of the basitarsus and distinctly longer than the width of the tibia. Metasoma as long as head plus thorax ( Fig. 6A ).
