A new species of Trichorhina Budde-Lund, 1908 (Isopoda: Oniscidea: Platyarthridae) from Paraná caves, southern Brazil

Abstract

Th e genus Trichorhina Budde-Lund, 1908 in Brazil includes 22 described species, four of which occur in caves. Th e present work aims at describing the fi rst cave species for the state of Paraná. Trichorhina kaingangi n. sp. was collected in Água Boa cave, municipally of Almirante Tamandaré, and Ermida Paiol do Alto cave, municipally of Adrianópolis, both in the Açungui karst area.

Shedding light into Brazilian subterranean isopods (Isopoda, Oniscidea): expanding distribution data and describing new taxa

“…Molecular data contradict its monophyly within Platyarthridae (Javidkar et al 2015, 2017). The members of the genus exhibit reduced size, body pigments and/or ommatidia are reduced or absent, the dorsal surface is covered with fan-shaped scale-setae, and the pereopods are short, bearing sternal fringes of setae (see Campos-Filho et al 2014, 2015b, 2016). The dorsal scale-setae reduce the adhesion of microparticles facilitating the movement of the animals in non-consolidated substrates.…”

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.…”

Taxonomic revision of Brasiloniscus (Oniscidea, Pudeoniscidae) with description of a new species

“…In the last years, our knowledge of the diversity of terrestrial isopods from Brazil has increased considerably and, to date, ca 200 species are known, including species from the subterranean environment (Schmalfuss 2003;Araujo & Quadros 2005;Souza et al 2006Souza et al , 2010Souza et al , 2011Souza et al , 2015Araujo & Taiti 2007;Sokolowicz et al 2008;Campos-Filho & Araujo 2011a, 2011bCampos-Filho et al 2012, 2013a, 2013b, 2015a, 2015b, 2016, 2017a, 2017b, 2017cCosta et al 2014;Zimmermann et al 2015;Cardoso et al 2016).…”
