Taxonomic biodiversity of geniculate coralline red algae (Corallinales, Rhodophyta) from the Macaronesian region: summary and analysis

Abstract

A catalog and critical review of species and infraspeciWc taxa of non-fossil geniculate coralline red algae (Corallinales, Rhodophyta) previously reported from the Macaronesian region are presented along with an assessment of species diversity in the region. Published records of geniculate coralline algae are included along with comments relating to type material. Within the catalog, taxa are organized alphabetically by genus and within this by Wnal epithet. From the 31 taxa recorded, 4 are based on type collections from Macaronesian localities. The types of most species and infraspeciWc taxa reported from the region have yet to be re-examined in a modern context, and most Macaronesian records require veriWcation. The biodiversity of Macaronesian geniculate coralline algae may be lower than current information indicates
