Close to P. verreauxii, but distinguished by its less spiny head, arched vertex, 

 and plainer pronotum, with very different median ridge. The abdomen is more 

 slender and not wrinkled. The front coxae are also very different, being quite 

 unarmed. It was taken in the sweep net when beating shrubs on the borders of 

 a creek.
