Terminal males with strongly enlarged and forward pointing lateral parts of pereonite 1. Pereonites dorsally smooth or with low transverse ridges. Pleotelson lateral margins smooth. Eyestalk length at least twice greatest width. Antennula article 1 at most as long as eyestalk. Mandible palp present. Pereopod I carpus oval, with 2 straight robust setae on posterior margin; propodus with 2 robust setae on posterior margin. Pereopod II carpus and propodus posterior margin with a few short robust setae. Uropod endopod straight, apex rounded truncate. Etymology. The genus name incorporates the Greek ρύος (krios or kryos) meaning cold, alluding to the Antarctic-subantarctic distribution of its component species. ... : Published as part of Just, Jean & Wilson, George D.
