Cylindroniscus platoi (Isopoda: Oniscidea: Styloniscidae), a new cave-dwelling species from Lagoa Santa Karst, Southeastern Brazil

Abstract

The new species Cylindroniscus platoi n. sp. is herein described. As far as known, the species occurs only in three caves developed in a continuous limestone outcrop at Pedro Leopoldo municipality, Minas Gerais State. Cylindroniscus platoi n. sp. is regarded as an endemic troglobite based on its limited distribution and on non-obvious troglomorphisms found on its body surface.

New species and new records of terrestrial isopods (Crustacea, Isopoda, Oniscidea) of the families Philosciidae and Scleropactidae from Brazilian caves

“…The diversity of the subterranean Oniscidea from Brazilian caves has been recorded in many contributions (e.g., Souza et al 2006Souza et al , 2010Souza et al , 2015Ferreira et al 2010Ferreira et al , 2015Campos-Filho & Araujo 2011;Campos-Filho et al 2014, 2016, 2017b, 2017c, 2019, 2018Pellegrini & Ferreira 2016;Trajano et al 2016;Bastos-Pereira et al 2017;Fernandes et al 2018Fernandes et al , 2019Bichuette et al 2019). However, the taxonomic impediment is still a major consequence of a delay in the recognition of this fauna, considering that taxonomists that are still active are overloaded and/or face current bureaucratic obstacles, hindering the advance of this knowledge (Ebach et al 2011;Campos-Filho et al 2014;Coleman 2015).…”

Unique and fragile diversity emerges from Brazilian caves – two new amphibious species of Xangoniscus Campos-Filho, Araujo & Taiti, 2014 (Oniscidea, Styloniscidae) from Serra do Ramalho karst area, state of Bahia, Brazil

“…To date, about 210 species are known from Brazil, 70 of which, belonging to the families Styloniscidae, Philosciidae, Scleropactidae, Dubioniscidae, Platyarthridae, Porcellionidae, Armadillidae, Pudeoniscidae, and Armadillidiidae, are recorded from Brazilian caves. Thirty-two taxa are considered to be troglobites (obligatory and restricted to caves), several are troglophiles (facultative cave species), and some species are possibly trogloxenes (Souza et al 2011;Campos-Filho et al 2014, 2015a, 2015b, 2016, 2017a, 2017b, 2018Bastos-Pereira et al 2017;Fernandes et al 2018Fernandes et al , 2019Cardoso et al 2020aCardoso et al , 2020bCardoso et al , 2021. The species placed into the last two categories are difficult to assign into a correct subterranean category due to the scarcity of distribution data outside caves.…”
