Abstract

After a study of the type specimens, as well as supplementary materials of the eastern Pacific hermit crab Pagurus gladius (Benedict, 1892), this taxon is transferred to the genus Spathapagurus Lemaitre and Felder, 2011, and a full redescription and illustrations are presented. Morphological similarities of Benedict’s taxon with three other eastern Pacific species (Pagurus albus (Benedict, 1892), Pagurus perlatus H. Milne Edwards, 1848Milne Edwards H. 1848.

While examining museum specimens during this study, one female specimen representing a new species of Pagurus Fabricius, 1775, was discovered. This new species, named Pagurus marysolae sp. nov., is fully described and illustrated, and is assigned to Group II (“exilis”) of Pagurus.
