Hum. You need to knock the pollen off to see what colour the hairs are. Pale hairs on hind tibia would be OK for carantonica. The propodeum looks 'rough' which is also a good sign. But the abdominal tergites don't have enough of a hair fringe for me, and the tergites look quite glossy, so A.nigroaenea is a possible - though that would have to have bright orange hairs on hind tibia.
