This species differs from unicolor, Eaffr., from Zanzibar, by its 

 larger size, and the tenth joint of the antennae, which is more 

 transverse, the eleventh larger, and the prothorax which is a little 

 shorter.

This species differs from nigripennis, Eaffr., from Zanzibar, by the 

 seventh, eighth, and ninth joints of the antennae being larger, and 

 by the different sculpture of the head, and also by the longer elytra.
