A new species of Atlantoscia Ferrara & Taiti, 1981 (Oniscidea: Philosciidae) from Rio Grande do Sul, Brazil

Abstract

To date the genus Atlantoscia Ferrara and Taiti, 1981 includes two species, A. floridana (van Name, 1940) and A. rubromarginata Araujo and Leistikow, 1999. The species Atlantoscia petronioi sp.n. is described on the basis of material collected in a coastal dune forest area of the southern Rio Grande do Sul state, Brazil. This new species is characterized by antenna with accentuate setose sulcus from the peduncle to the distal article of the flagellum, outer endite of maxillula with slender seta among the outer group teeth and accessory tooth, one trifid tooth in the inner group, and male pleopod 1 endopod with distal part pointed and subapically not swollen.

Taxonomy and molecular phylogeny of the Neotropical genusAtlantoscia(Oniscidea, Philosciidae): DNA barcoding and description of two new species

“…The new species resembles A. petronioi and A. rubromarginata in the shape of the male pleopod 1 endopod but can be distinguished by the number of aesthetascs on antennula (8 + 2 vs. 12 + 2 in A. petronioi and 6 + 2 in A. rubromarginata ), and by the shape of the male pleopod 1 exopod, which differs from all other species within the genus, including A. inflata sp. nov. described herein (see descriptions and illustrations in Ferrara & Taiti, ; Araujo & Leistikow, ; Campos‐Filho et al ., , ).…”

“…In South America, about 31 genera are recorded including Atlantoscia Ferrara & Taiti, (Schmalfuss, ), which currently consists of five species (Campos‐Filho et al ., ). Atlantoscia floridana (Van Name, ) was originally described from Florida, USA; Atlantoscia rubromarginata Araujo & Leistikow, , from Sergipe, Brazil (Araujo & Leistikow, ); Atlantoscia petronioi Campos‐Filho, Contreira & Lopes‐Leitzke, , from Rio Grande do Sul, Brazil; and the two most recently described species, Atlantoscia sulcata Campos‐Filho, Lisboa & Araujo, , and Atlantoscia ituberasensis Campos‐Filho, Lisboa & Araujo, , from the Brazilian states of São Paulo and Bahia, respectively.…”

“…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).…”
