Two new Diastylis (cumacea: Diastylidae) from Antarctic waters: Diastylis andeepae and D. catalinae
Two new deep-sea cumaceans, Diastylis andeepae and D. catalinae are described from the Weddell Sea. Diastylis andeepae n. sp. can be distinguished from other members of the genus by a combination of characters including: carapace with small tubercles all over and anterior part with an arched row of...
