20a |
Face with a white crossband that is bordered dark brown to black dorsally and ventrally.
Described from the Cape Province and Mozambique, but a specimen from Morocco seems te belong to this species. The arista is almost imperceptably haired (rays thin and about as long as diameter of arista), but arista not straight as it is in A. caesia. It could easily be mistaken for A. amoena or algeriensis exept for the banded hind tibia and almost bare arista. |
