This sawfly specimen has been found in winter wheat crop of Voronezh province (Black earth region of the European parth of Russia) and has 8-9 mm body length. It has totally black coloration. May be someone knows what genus it might belong to.
For me, it looks like a Pompilidae male of the genus Anoplius. A. nigerrimus is the most probable species, but other species are also possible. Can you make a photo of last sterna (tip of abdomen) in good quality?
