A new name for a large Phyllonotus species from the Dominican Republic, Greater Antilles

A replacement name for Murex asperrimus Lamarck 1822 is provided as Lamarck did not realize that the name was preoccupied by Murex asperrimus Gmelin, 1791, and thus invalid. The replacement name, Phyllonotus feliciae Berschauer & Petuch n. sp., is endemic to the island of Hispaniola; a description and illustrations of recently collected specimens of this rare and distinctive species are provided.
