What is "phoratopus"

Phoratopus remex is a species of isopod crustacean known from only two specimens, and first described in 1925 by Herbert Matthew Hale (1895–1963). It lives on the continental shelf at Encounter Bay and Fowlers Bay, South Australia. It is so unlike all other isopods that it is placed in its own family, Phoratopodidae and suborder, Phoratopidea.
