Abstract

The uristid lysianassoids are reported for the first time from Korean waters with a redescription of Anonyxabei Takekawa & Ishimaru, 2001 and the description of Anonyxexilipessp. n.Anonyxabei is characterized by a distinctively small projection of the posterodistal corner on epimeron 3, different from all species of the Anonyxnugax group which share a constriction at the point of insertion of a distal seta on the inner ramus of uropod 2. Anonyxexilipessp. n. is included in the Anonyxlaticoxae group characterized by the unconstricted inner ramus of uropod 2. This new species is distinguished from other A.laticoxae group species by the longer and more slender carpus and propodus of pereopod 6, and the non-lobate merus of pereopod 7.
