A new species of Eualus Thallwitz, 1891 and new record of Lebbeus antarcticus (Hale, 1941) (Crustacea: Decapoda: Caridea: Hippolytidae) from the Scotia Sea
A new species of Eualus Thallwitz, 1891 and new record of Lebbeus antarcticus (Hale, 1941) (Crustacea: Decapoda: Caridea: Hippolytidae) from the Scotia Sea
Eleven specimens representing two hippolytid genera, Eualus Thallwitz, 1891 and Lebbeus White, 1847, were sampled recently from the Scotia Sea (1517-2598 m). Seven specimens are described and illustrated as Eualus amandae sp. nov., and its morphology is compared with those of previously described species. Four female specimens, morphologically consistent with Lebbeus antarcticus (Hale, 1941), are described and illustrated to supplement previous descriptions of this rarely collected bathyal species. Partial COI mtDNA and 18S rDNA sequences were generated for both species. Only limited DNA sequences are available for species of Hippolytidae and the COI trees presented are used to illustrate that the new species is genetically distinct from other species for which COI sequences are available. The presence of fixed and unique mutations in the COI sequences of the new species indicates that they are genetically distinct from all other species in GenBank. This record enhances existing knowledge of Antarctic invertebrate biodiversity and species richness of decapod crustaceans in the Southern Ocean.

Abstract
Eleven specimens representing two hippolytid genera, Eualus Thallwitz, 1891 and Lebbeus White, 1847, were sampled recently from the Scotia Sea (1517-2598 m). Seven specimens are described and illustrated as Eualus amandae sp. nov., and its morphology is compared with those of previously described species. Four female specimens, morphologically consistent with Lebbeus antarcticus (Hale, 1941), are described and illustrated to supplement previous descriptions of this rarely collected bathyal species. Partial COI mtDNA and 18S rDNA sequences were generated for both species. Only limited DNA sequences are available for species of Hippolytidae and the COI trees presented are used to illustrate that the new species is genetically distinct from other species for which COI sequences are available. The presence of fixed and unique mutations in the COI sequences of the new species indicates that they are genetically distinct from all other species in GenBank. This record enhances existing knowledge of Antarctic invertebrate biodiversity and species richness of decapod crustaceans in the Southern Ocean.
