Exoprosopa magnipennis
Bezzi, 1924: 344
,
Kenya
[examined]
This species is readily recognized by the extensive reddening of the head and body including the antennae. The infuscation of the wings is darker and more contrasting with the hyaline areas than in
E. brevinasis
which it most closely resembles.
Bezzi (1924)
gives a full description.
