The rare and unusual deep water hermit crab genera Porcellanopagurus Filhol and Solitariopagurus Turkay are reported for the first time from Hawaiian waters. Each genus is represented by a single specimen collected from Penguin Banks, off the southwest coast of Moloka'i, Hawaii. The specimen of Porcellanopagurus is identified as P. platei, a species that has not been reported since its original description in 1902 based on specimens from the Juan Fernandez Islands off southern Chile. Therefore, the record is a major range extension for the species. The specimen of P. platei from Hawaii is an ovigerous female found inhabiting a fissurellid limpet shell; the species is redescribed based on type material. The specimen of Solitariopagurus, S. tuerkayi, was found carrying (inhabiting) one half of a bivalve mollusk shell (the lucinid Ctena bella), the first confirmation of this habitat for the species. A second specimen, photographed but now missing, was associated with a different species of bivalve (a mytilid). In addition to being new records of these genera for the Hawaiian Islands, the report also marks the first record of the genus Porcellanopagurus from the central Pacific and only the second record of the genus Solitariopagurus in the northern hemisphere.
