Catalogue of terrestrial isopods (Isopoda, Oniscidea) from Peru, with new records of Circoniscus ornatus (Scleropactidae) and Ethelum americanum (Eubelidae)
Abstract:This work aims to list all known species of terrestrial isopods from Peru until September, 2020. Also, Circoniscus ornatus (Verhoeff, 1941) (Scleropactidae) and Ethelum americanum (Dollfus, 1896) (Eubelidae) are recorded for the first time from Nueva Alianza and Nuevo Sucre, Contamana, Loreto department, Peruvian Amazon rainforest.
“…DISTRIBUTION. The species has been recorded in the Lesser Antilles and northeast of South America [Schmalfuss, 2003;Campos-Filho et al, 2018;Ocampo-Maceda et al, 2022]. This is the first record of the family, genus, and species for Colombia, and the first for terrestrial isopods in the department of Caquetá (Fig.…”

“…The genus Circoniscus comprises 11 species with a distribution restricted to South America (Schmidt 2007;Campos-Filho et al 2017Ocampo-Maceda et al 2022). To date, except for Circoniscus pallidus Arcangeli, 1936, in the State of São Paulo, and Circoniscus caeruleus Campos-Filho, Sfenthourakis & Bichuette, 2023, in the state of Mato Grosso, all species are recorded from the State of Pará (Campos-Filho et al 2018.…”
Abstract. Two new species of terrestrial isopods are described from iron ore caves in Brazil, within the Amazon biome, Circoniscus mendesi López-Orozco, Campos-Filho & Bichuette sp. nov. and C. xikrin López-Orozco, Campos-Filho & Carpio-Díaz sp. nov. (Scleropactidae). In addition, the knowledge of the distribution of Ctenorillo ferrarai Campos-Filho, Araujo & Taiti, 2014 (Armadillidae) is extended to Parauapebas, and Benthanoides tarzan Cardoso & Ferreira, 2023 to south area of the Campos Ferruginosos National Park, both in the State of Pará. Moreover, a distribution map and photographs of the species are given.
“…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.)…”
A new genus of Pudeoniscidae from Peru is described, Loretoniscus gen. nov., including a new species: Loretoniscus mashiriaensis gen. et sp. nov. The new genus is characterized by pereonite 1 epimera without dorsolateral furrows, pereonites 1 and 2 without ventral lobes, telson with distal portion covering uropod endopods, and pleopod 1–2 exopods with respiratory areas. This is the first record of the family Pudeoniscidae from Peru, considerably extending its distribution in the Neotropical region.
