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

Abstract

After the examination of a large collection of Oniscidea from caves in the Brazilian states of Bahia, Minas Gerais, Pará, Sergipe and São Paulo, 12 species were recognized in the families Philosciidae and Scleropactidae. Four new species are described: Alboscia jotajota sp. nov. from the Açungui group; Androdeloscia akuanduba sp. nov. and Amazoniscus spica sp. nov. from the Carajás Formation; and Metaprosekia igatuensis sp. nov. from the Quadrilátero Ferrífero karst region. In addition, Atlantoscia inflata, Benthana longicornis, B. olfersii, B. picta and Paratlantoscia rubromarginata (Philosciidae) are recorded from Brazilian caves for the first time; and Benthana iporangensis, B. taeniata and Circoniscus bezzii (Scleropactidae) have the knowledge of their distribution extended to cave habitats.

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

“…Benthana olfersii – Campos-Filho et al 2018a: 11 (for previous records). — Campos-Filho et al 2020: 17, fig. 14.…”

“…In the last years, our knowledge on the diversity of Oniscidea from subterranean environments has increased considerably (e.g. Bedek et al 2011, 2019; Taiti 2014; Reboleira et al 2015; Kashani et al 2016; Campos-Filho et al 2019, 2020, 2022a; Cardoso et al 2020a, b; Bastos-Pereira et al 2017, 2022; Taiti & Montesanto 2018, 2020; Taiti et al 2018; Taiti & Cardoso 2020). The diversity of terrestrial isopods in subterranean environments is closely related to favourable habitat conditions, such as high humidity, the occurrence of substrate heterogeneity, and a variety of micro-habitats (Fernandes et al 2016, 2019; Reboleira et al 2022).…”

“…In Brazil, more than 220 species of Oniscidea are known, of which 79 were recorded in caves. Among them, 38 are considered troglobites (obligatory cave-dwellers) and several are troglophiles (facultative cave-dwellers) (Trajano & Carvalho 2017; Campos-Filho et al 2018a, 2019, 2020, 2022a, b, c; Fernandez et al 2019; Cardoso et al 2020a, 2020b, 2021, 2022a, 2022b, 2023; Bastos-Pereira et al 2022). However, for some Oniscidea taxa, these subterranean categories were not properly assigned due to the lack of efficient sampling outside caves.…”

First record of Pudeoniscidae Lemos de Castro, 1973 (Oniscidea) from Peru, with the description of a new genus and species

“…However, these conclusions are still under debate. About 480 species of Oniscidea have been recorded in South America, most of them placed in the families Philosciidae Kinahan, 1857 andScleropactidae Verhoeff, 1938 (Schmalfuss 2003;Schmidt & Leistikow 2005;Schmidt 2007;Campos-Filho et al 2018a, 2020, 2021bCardoso et al 2020aCardoso et al , 2020bCardoso et al , 2021Cardoso et al , 2022aCardoso et al , 2022bOcampo-Maceda et al 2022;Carpio-Díaz et al 2018Grangeiro et al 2021;López-Orozco et al 2016. To date, in Peru, 24 species distributed in 12 genera are known so far, i.e., Ligia Fabricius, 1798 (1 sp.)…”

Additions to the millipede fauna of an Amazonian ferruginous landscape: a new species of Pseudoporatia Golovatch, 1999 widespread in rock outcrops (Diplopoda, Polydesmida, Pyrgodesmidae)

“…To date, the economy of the Serra dos Carajás region has been intensified due to mining operations in its huge deposits of iron ore, influencing directly the local urban development and environmental pressures on land use (Palheta et al 2017). The rock outcrops of this region harbor numerous endemic invertebrates (Chagas-Jr & Bichuette 2018; Brescovit et al 2018; Asenjo et al 2019; Campos-Filho et al 2020; Junta et al 2020; Teodoro et al 2021), including some millipede species such as Glomeridesmus spelaeus Iniesta & Wesener, 2012 (Glomeridesmida Latzel, 1884, Glomeridesmidae Latzel, 1884), Pseudonannolene spelaea Iniesta & Ferreira, 2013 (Spirostreptida Brandt, 1833, Pseudonannolenidae Silvestri, 1895), Parastenonia carajas Bouzan & Iniesta, 2019 (Polydesmida Leach, 1815, Chelodesmidae Cook, 1895), and Stemmiulus brasiliensis Iniesta & Ferreira, 2015 (Stemmiulida Pocock, 1894, Stemmiulidae Pocock, 1894) (Iniesta et al 2012; Iniesta & Ferreira 2013, 2015; Bouzan et al 2019).…”
