Distribution
East and South Africa; from southeastern Kenya to Zimbabwe.
Comments
The male of this subspecies are externally very similar to A. bipartita despite the considerable differences in genitalia. In A. brunnea bipartitoides, the fw ground colour is more pale grey, particularly in fresh specimens, the hw apical region is darker grey, and a distinct projection at the hw anal angle is absent. As the two taxa apparently co-exist for most of their ranges, the external similarity could be enforced by Müllerian mimicry. The nominate subspecies of A. brunnea occurs in western Kenya (Kakamega) and no intermediate forms between the two subspecies have been taken, but A. brunnea has not yet been recorded from central Kenya.
