Differs conspicuously from C. {Bemhidium) master si, SI., the only

 much more prominent; prothorax much more narrowed to base 

 and more strongly rounded on sides; elytra less convex, more oval 

 (sides more strongly rounded), base more emarginate, shoulders 

 more advanced and less angulate: the whole upper surface more 

 strongly shagreened.
