  Checklist of the littoral gastropods (Mollusca Gastropoda) from the Archipelago of the Azores (NE Atlantic)

  ABSTRACT
  The littoral gastropods (Mollusca Gastropoda) are probably the best known marine invertebrates in the Azores. Recently, this fauna has been studied by several authors, resulting in a regular increase of the knowledge of its biodiversity. However, the data are scattered by numerous publications, making it clear the need of an updated checklist of the littoral gastropods from the Azores. Our study presents a checklist of the littoral gastropods from the Azores, based on data from the literature and from new material examined. The occurrence of Caecum gofasi, Cerithiopsis cf. nana, Curveulima dautzenbergi, Liostomia mamoi, Mangelia scabrida, and Rissoella contrerasi is reported for the first time. Our findings expand the known regional biodiversity of littoral gastropods to 281 species. A list of dubious records and misidentifications is also presented, as well as the reasons for the exclusion of these species from the checklist.
