Four new species of Thouarella (Anthozoa: Octocorallia: Primnoidae) from Antarctic waters

Rebeca Zapata-Guardiola, Pablo J. López-González

Abstract

Four new Antarctic species of the genus Thouarella, all of them belonging to the subgenus Thouarella, are described and illustrated from material collected at the South Georgia and the South Sandwich Islands, and off Atka Bay (eastern Weddell Sea) on the Polarstern cruises ANT XIX/5 (LAMPOS), and ANT XXIV/2 (ANDEEP-SYSTCO). The study of our new taxa allows us to describe a wider variation in the number of the distal cycles of polyp scales, as well as the existence in the genus (and subgenus) of additional species with planar colonial morphologies. The new species are compared with their closest congeners.
