Resumo
Morphological and molecular evidence suggests that the ghost shrimp population in Brazil that had been assigned to Callichirus major (Say, 1818) represents a distinct species. A neotype of C. major is designated in the interest of nomenclature, because the holotype is no longer extant. Based on material from Brazil, a new species, Callichirus corruptus, is described. Differentiating characters between the new species and C. major are discussed and an identification key to species of Callichirus is provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:29450E54-130A-4838-B923-F9676609DB3A.
