ResumoABSTRACT Two chromatic morphs of Pagurus lanuginosus de Haan, 1849, of Imafuku and Ikeda (1995) are here recognized as 2 distinct species: the black spot morph is referred to true P. lanuginosus,and the white spot morph is described herein as a new species, P. maculosus. The range of P. maculosus appears restricted to the Pacific coast of the Japanese main islands from Boso Peninsula to Amakusa, Kyushu. Pagurus lanuginosus is considered to be more widely distributed in the Japanese main islands, Korea, and the Russian coast of the Sea of Japan. Within the range of the new species, P. lanuginosus sometimes occurs sympatrically. A neotype is designated for P. lanuginosus to establish its taxonomic status, since its type material is no longer extant. In addition to the coloration, these two species differ morphologically from each other in the number of calcareous teeth of the right cheliped dactyl and the presence or absence of an enlarged tubercle on the merus of the right cheliped.
