Although I have only seen a single female specimen of this 
species, the differences in the sculpturing and coloration are so 
marked that it cannot easily be confounded with any other of its 
allies ; the short and very strongly punctured thorax and the 
rugosities of the elytra, which resemble those of the genera Edusia 
and Abirus, instead of the usual irregular rough appearance, will 
at once distinguish this species.
