Stegophryxus hyptius, heretofore known only as a parasite of Pagurus longicarpus in New England, is recorded infesting P. longicarpus in Georgia P. annulipes in North Carolina and Georgia, and P. bonairensis and P. miamensis in southern Florida. The only known specimens of Stegophryxus thompsoni, the types, from an unknown host in Chile, are redescribed. A new species from California and Baja California, S. hyphalus is described as a parasite of Parapagurodes laurentae and P. makarovi. These three species, the only members of the genus, are illustrated in detail and their distribution discussed.
