A new monotypic hermit crab genus, Chanopagurus (Paguridae), is described for a new species, C. atopos, based on an ovigerous female specimen collected in deep water (880 m) off the coast of Taiwan. The single specimen is unique in having: 13 pairs of quadriserial gills which include two reduced but functional pleurobranchs on the fifth and sixth thoracic somites; ocular peduncles concave mesially; reduced, unpigmented corneas located lateroventrally; ocular acicles each armed with very small spine; unpaired left gonopore; and paired first pleopods. The new species shares with Propagurus McLaughlin and de Saint Laurent, the presence of reduced pleurobranchs on the fifth and sixth thoracic somites. The superficial resemblance of C. atopos with species of Tomopaguropsis Alcock, in having subequal chelipeds, and long, dense setae on the antennae, chelipeds and second and third pereopods, is considered homoplasy.
