Corella sp.

Material:

Lobos Island, 37° S– 55°21’ W, 69m, 29/12/1966, Calypso survey n°169.

The single specimen of 4.5cm is much damaged. The only part remaining in acceptable condition is the rectum. The anus has numerous finger-like lobes. The gonoducts are clearly apparent along the rectum with some eggs into the oviduct. Both genital papillae open close to the anus. This structure is reminiscent of that of C. brewinae but no reliable identification can be made with so few anatomical characters.

Abstract

In the Southern Hemisphere the species attributed to Corella eumyota, Traustedt, 1882 are likely more varied than previously expected. This ascidian species was described from specimens collected at Valparaiso (Chile). Until now it was considered as a widely distributed species in the southern hemisphere. New collections from Chile and the Antarctic area have allowed to separate two species and re-establish Corella antarctica Sluiter, 1905 as a valid species (Alurralde 2013).A morphological reexamination of many specimens from the MNHN collections and especially recent surveys as CEAMARC and REVOLTA confirms that Antarctic specimens from the Antarctic Peninsula and Terre Adélie obviously differ from sub-Antarctic material more varied than previously estimated. On the other hand, C. eumyota invasive in Europe (Lambert 2004) has been shown to be the same as specimens from Chile, New Zealand and other sub-Antarctic regions. The present morphological study compares Corella from different regions and describes a new species Corella brewinae n. sp that is found living mixed with C. eumyota populations.
