| Abstract |
Some of the deep-water molluscs collected during the Marion Dufresne (MD55) expedition off SE Brazil have been studied in recent papers. The present work focuses on the heterobranch family Architectonicidae. Four species have their occurrence expanded to/in the SW Atlantic (new records in parenthesis): Psilaxis clertoni Tenório, Barros, Francisco & Silva, 2011 (off Cabo Frio, Rio de Janeiro, 610 m); Solatisonax rudigerbieleri Tenório, Barros, Francisco & Silva, 2011 (Canopus Bank, off Fortaleza, Ceará state, 260 m; off Cabo Frio, Rio de Janeiro, 610 m); Spirolaxis centrifuga (Monterosato, 1890) (off Linhares, Espírito Santo, 340-360 m); Spirolaxis cf. lamellifer (Rehder, 1935) (off Linhares, Espírito Santo, 640 m depth and off Cabo Frio, Rio de Janeiro, 610 m). Moreover, we describe herein a new architectonicid species, namely Pseudotorinia phorcysi spec. nov., collected off Cabo Frio, Rio de Janeiro state, 430-450 m. Its diagnostic features are: a strong beaded sculpture, angular outline and prominent peripheral keel formed by a strong beaded spiral rib and a lower, weaker rib, with fine axial growth lines between them. |
