Coptorhina angolensis Arrow, 1906
Dagnosis. This species is most similar to C. klugii but can be separated from it by the shape of the transverse carina of the pronotum which has four distinct tubercles in larger specimens. From other species it differs in having narrow lateral borders of the pronotum and evenly rounded lateral sides of the pronotum. From C. nitefacta it also differs in having densely punctured upper side of body.
Distribution. The range of this species is not quite clear because of limited material available. It is known from a few localities in Angola and was recently collected in north-eastern Namibia (Caprivi).
