| Abstract |
The Walters Shoals is a huge isolated submerged seamount about 700 km south off Madagascar reaching 15 or 18 m below the surface (Collette & Parin, 1991; Galetti et al., 2018). It was discovered at the southern end of the Madagascar Ridge in 1962. Such seamounts 'are regarded ashotspots of marine biodiversity and are home to many endemic species' (IUCN, 2017). The MNHN oceanographic cruise visited the Walters Shoals in 2017 as part of the project "Conservation and Sustainable Use of Underwater Mountain Ecosystems and Hydrothermal Sources in the South West Indian Ocean. Beyond Areas of National Juridiction" by the Global Program for the Marine and Polar Environment of the IUCN that was supported by the French Fund for the Global Environment (FFEM). The target of the project was the 'deepening of scientific knowledge, strengthening the governance and improving the integrated management beyond the areas under national juridiction' (Dr. Philippe Bouchet, pers. comm.). Therefore, the biodiversity should be confirmed and Dr. Bouchet invited me to work on the OVLUIDAE, PEDICULARIIDAE and TRIVIOIDEA. The first step is the description of a seemingly endemic Triviid taxon within the genus Trivellona Iredale, 1931 as T. inopinata n. sp. |
