Distribution . Known only from Panama (Fig. 123) . 



Etymology . undulatus: Latin = wavy. Gorham' s name 

 probably refers to the wavy central elytral band, as 

 illustrated in the original description. 



Remarks . Ischyrus undulatus is most similar to I. 

 bellus Guerin and J. nitidior Crotch in pronotal color 

 pattern and body form. Both I. bellus and I. nitidior have 

 the elytra completely banded; in I. undulatus the elytral 

 markings are broken into spots.
