A single specimen collected from the Campanian Wenonah Formation in New Jersey forms the basis for definition of a new genus and species of dromiid crab, Costadromia hajzeri. This occurrence represents the oldest known occurrence of Dromiidae. The discovery represents only the second decapod crustacean found in the formation and brings the total number of Cretaceous decapods in New Jersey to 23.
