 Remarks . Ischyrus tripunctatus is most similar to I. 



pardalinus Guerin and I. impressopunctatus Crotch in color 



pattern. Ischyrus pardalinus has a red head with black 



basal spot, and a free subhumeral spot; I. tripunctatus has 



an entirely black head, and fused subhumeral and scutellar 



spot. Ischyrus impressopunctatus has the basal and central 



elytral markings interrupted by orange, the central spot 



does not connect with the suture; I. tripunctatus has the 



basal and central elytral markings complete, broadly 



connected to the suture.
