The genus Trichorhina Budde-Lund in Brazil, with description of seven new species (Isopoda, Oniscidea, Platyarthridae)

Abstract

Seven new species of Trichorhina Budde-Lund, 1908 are described, six from Southeastern Brazil, T. biumbonata sp. nov., T. lenkoi sp. nov., T. myrmecophila sp. nov., T. orensis sp. nov., T. sexdens sp. nov., T. tropidocerata sp. nov., and one from Central Brazil, T. crassisetae sp. nov. An emended diagnosis for the genus and a key to the 19 species recorded from Brazil are provided. Trichorhina acuta Araújo & Buckup, 1994 is recorded to state of Mato Grosso do Sul.

Terrestrial isopods (Crustacea: Isopoda: Oniscidea) from Brazilian caves

“…nov. is readily distinguishable by the shape of the male pleopod 1 exopod, ovoidal without any posterior lobe. In having the molar penicil of the mandible consisting of a single unbranched seta, the new species resembles Trichorhina lenkoi Souza, Araújo & Campos‐Filho, , Trichorhina macrops Souza‐Kury, , Trichorhina myrmecophila Souza, Araújo & Campos‐Filho, , Trichorhina orensis Souza, Araújo & Campos‐Filho, , Trichorhina paraensis Souza‐Kury, , and Trichorhina sexdens Souza, Araújo & Campos‐Filho, . It differs from these species in the lack of eyes, number of aesthetascs of the antennule, and shape of male pleopod 1.…”

“…Among the 19 species of Trichorhina presently known from Brazil (Souza et al ., ), only two species are known to be blind and colourless: Trichorhina pittieri (Pearse, ) and T. brasilensis . Trichorhina anhanguera sp.…”

“…To date, Trichorhina includes 63 species, of which 19 are recorded from Brazil (Schmalfuss, 2003;Souza et al, 2011). The monophyly of the genus is questionable and in need of revision.…”

Three new species of terrestrial isopods (Crustacea, Isopoda, Oniscidea) from Brazilian caves

“…70 described species widely distributed in tropical and subtropical areas (Schmalfuss, 2003;Souza et al, 2011;Campos-Filho et al, 2014). In Brazil, the genus includes 23 species, five of which occurring in caves: Trichorhina anhanguera Campos-Filho, Araujo & Taiti, 2014, Trichorhina curupira Campos-Filho, Araujo & Taiti, 2014, Trichorhina guanophila Souza-Kury, 1993, Trichorhina kaingangi Campos-Filho, 2015, and Trichorhina yiara Campos-Filho, Araujo & Taiti, 2014(Souza-Kury, 1993Campos-Filho et al, 2014.…”

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).…”
