Open-access Cave-dwelling terrestrial isopods (Crustacea: Isopoda: Oniscidea) from Florianópolis Island, Brazil: review and description of three new species

Terrestrial isopods are a group of peracarid crustaceans characterized by remarkable taxonomic diversity, and Brazil has a large number of recorded species. In this contribution, three new species of terrestrial isopods are described from caves in the municipality of Florianópolis, Santa Catarina, Brazil. Additionally, the distribution of Atlantoscia meloi Campos-Filho & Araujo, 2015, Benthana picta (Brandt, 1833) (Philosciidae), and Pudeoniscus birabeni Vandel, 1963 (Pudeoniscidae) is expanded to include caves in Florianópolis. Our findings also reveal the first troglobitic species from the island of Florianópolis and the second of the genus. Finally, a distribution map, an identification key, and photographs of the recorded species are provided.
