A new species of shark belonging to the family Ginglymostomatidae is herein described; the new species show a wide distribution in the Tropical Eastern Pacific, where it is endemic. Ginglymostoma unami sp. nov. was previously recognized as G. cirratum exhibiting an amphi-American distribution; however that species is now considered to be restricted to the Atlantic Ocean. Ginglymostoma unami sp. nov. can be readily distinguished from G. cirratum by comparing several meristic characters such as the distance between the prebanchial and interdorsal regions, and that between posterior end of the second dorsal fin and the beginning of the caudal lobe, both being shorter; the new species also differs by the position of the insertion of the first dorsal fin with regard to the pelvic fins and in the form and number of keels on the dermal denticles and teeth morphology.
