Abstract

Anew polychaete species, Sphaerodoropsis kitazatoi (Annelida: Phyllodocida: Sphaerodoridae), is described from the abyssal Southwest Atlantic Ocean at the base of Sao Paulo Ridge (4204 m depth). This species was found in sediments impacted by a whale carcass. The new species has four longitudinal rows of macrotubercles and one transversal row per chaetiger and shares several characters with S. anae Aguado and Rouse, 2006 that is also associated with chemosynthetic environments. They can be clearly distinguished from S. anae and other Sphaerodoropsis species by the arrangement and the number of prostomial, body and parapodial papillae. (AU)
