Contribution de la mission La Planète Revisitée à la connaissance des araignées : 33 espèces nouvelles pour la Corse, dont deux nouvelles pour la faune de France (Arachnida, Araneae)

Abstract

Contribution of the mission Our Planet Reviewed to the knowledge of spiders: 33 species new to Corsica, including two species new for the French fauna (Arachnida, Araneae). As part of Our Planet Reviewed in Corsica 2019-2021 project, 364 spider taxa were inventoried. This mission made it possible to update the list of species recorded on the island: 33 species of spiders are added to the Corsican araneofauna, which goes from 687 to 721 taxa; two species are also new to the fauna of France, Orchestina longipes Dalmas, 1922 (Oonopidae) and Pseudeuophrys perdifumo van Helsdingen, 2015 (Salticidae). A comparison of sampling techniques is proposed, and for some new taxa comments on ecology or taxonomy are added. Finally, the main groups of species by type of habitat studied and a zoom on the “heritage” species are presented, in view of the recently published National Red List.
