Abstract: The lectotype of Pagurus minutus Hess, 1865 and the syntypes of Pagurus dubius(Ortmann, 1892)were compared. Pagurus minutus has proved to be a senior subjective synonym of Pagurus dubius. Hess's species is redescribed and illustrated in detail based on the type material and an abundance of additional specimens from Japan, Korea, and Taiwan. Notable intraspecific variations are seen in the right cheliped and dissimilarity of the third pereopod. In males, a tendency toward elongation of the right cheliped accompanied with reduction of the armature is found. The degree of dissimilarity in the third pereopods is stronger in females than in males. Pagurus minutus is most similar to P. filholi(De Man, 1887)and P. samuelis(Stimpson, 1858). The elongate dactyli of the second and third pereopods and the coloration in life immediately distinguish P. minutus from these other two species.
