The Northern Banded Groundling (Brachythemis impartita) looks very similar to the Southern Banded Groundling (Brachythemis leucosticta). 
Both species are widespread: B. leucosticta occupies most of tropical Africa and Madagascar, while B. impartita ranges north and south of the Sahara, and extends into Eurasia.
Until 2009, these two species were considered the same species.
Males Brachythemis impartita can be distinguished from males Brachythemis leucostita by the white veins near the wing tips.
Brachythemis leucosticta has dark veins near the wingtips.
In addition, in B. leucosticta the band around the pterostigma is much more dark en complete.
