The species exhibits the widest distribution within the subgenus Ambrysus, spanning parts of both the Nearctic and Neotropical biogeographic realms. Recent taxonomic revision has synonymized the subspecies A. pulchellus nitidulus and A. pulchellus pallidulus with the nominate form, and documented new country records from Honduras, Nicaragua, and Panama.
