A new species of the distinctive hermit crab genus Pteropagurus McLaughlin & Rahayu, 2006, P. spinulocarpus n. sp., is described and illustrated, bringing to three the number of species found to occupy empty pteropod mollusc shells. This new species is distinguished from other members of the genus by the presence of spines on the dorsal margins of the carpi of the ambulatory legs and by the absence of corneous spines on the ventral margins of the dactyls of these appendages. Additionally, a new genus and species, Dentalopagurus levii n. gen., n. sp. is described and illustrated based on three male specimens collected during explorations south of the Isle of Pines, New Caledonia. This new genus differs from other scaphopod dwelling genera and species in having well developed, paired male sexual tubes.
