This revision treats all known species of the genus 

 Ischyrus Lacordaire occurring from Panama north. A key to 

 the species, descriptions and illustrations of terms used, 

 habitus and genitalic illustrations for all species, 

 distribution maps, detailed species descriptions, complete 

 synonymies, label data from specimens studied, and 

 comparisons with similar species are presented to aid in the 

 identification of specimens. A list of all names used in 

 combination with Ischyrus and their current status is 

 presented to prevent future homonyms. A total of 26, valid 

 previously described species is addressed, nine new 

 synonymies made, and 16 new species described.
