A new genus is proposed for a distinctive new species of bivalve-inhabiting hermit crab. Its type species, Alainopagurus crosnieri sp. nov., is described and illustrated. Alainopagurus gen. nov. is compared with Porcellanopagurus and Solitariopagurus, two other pagurid genera with similar habitat adaptations.
