SW France yesterday. On a sedge in a wet area. About 6 mm long.

Assuming it is this genus, can we get to the species with these pics ?

Thank you Paul,

The photos are not that good, but I still tried to follow Grichanov's key. I cannot see any hair on the back, but the leg colours and the yellow spots on the abdomen led me to A. diaphana. Am I wrong ?

No hairs on the scutellum so it should not be diaphana...
