Two new species of bopyrid isopods, Pseudione stylopoda n. sp. and P. clevai n. sp., are reported from species in the family Stylodactylidae and are the first species described from members of this enigmatic caridean family. One of the new species is very close to the New Zealand taxon P. pontocari Page, 1985, especially in the form of the distinctive styliform shape of the endopods of pleopods IV and V in the female. The second new species has some similarity to P. elongata elongata (Hansen, 1897) in the shape of the female pleotelson, but is otherwise very distinctive within the genus. Additional literature records of bopyrids from species of Stylodactylidae for which specimens cannot be located are discussed.
