Recent Pacific collections included numerous specimens of gastropod-shell-inhabiting tanaidaceans of the subfamily Pagurapseudinae, from shallow waters off Vanuatu (7 to 21 m depth). The two sympatric species present are new to science, and are described herein. Pagurapseudes queirosi n. sp. is distinguished from other species with identical antennular flagellum and uropod segmentation by having only two pairs of pleopods (the other species having at least three pairs), and a large dorsal plumose seta, arising from a distinct tubercle on the merus of pereopod 1, inter alia. Macrolabrum mansoris n. sp. has a characteristic rostrum morphology, and three segments in the main flagellum of the antennule (all other congeneric species having either two or four segments).
