Brachythemis wilsoni Pinhey, 1952
Swamp Groundling
Type locality: Yambio, Sudan
Diagnosis
Mature male is similar to B. lacustris by (a) wings orange to dark amber at base, without dark postnodal bands; (b) no cell-doublings in radial planate of all wings, although rarely 1 or 2; (c) Abd red. However, differs by (1) larger size, Hw 25-28 mm; (2) orange on wings fades distally, concentrated in rays in subcostal and cubital spaces, extends about to Ax2-3 and not into triangle.
