    A new species of the ctenostomatous bryozoan genus Arachnoidea, Arachnoidea dhondti, is described. The species is epizooic on the hermit crab Parapagurus pilosimanus collected in the North Atlantic off the coast of North Carolina, USA at a depth of 550 m. The colonies are encrusting, forming linear chains or small patches on the anterior appendages of the hermit crab. The zooids consist of a short, proximal part, an oval middle part, together forming a broad basal plate, and a distal part forming an erect tube-shaped peristomium. The species is distinguishable from other members of the genus by a row of crystalline structures along the lateral margin of the basal plate. The crystalline structures are considered to be homologous with the crenellations in other species in the genus.
