Biospeleological surveys conducted in the last decades in Australia, Asia and South America have partly modified this scenario and to date 331 troglobiotic Oniscidea species are known (Taiti and Gruber, 2008; Taiti and Xue, 2012; Tabacaru and Giurginca, 2013; Campos-Filho et al, 2014; Taiti 2014; Souza et al, 2015; Taiti and Wynne, 2015)
Nowadays about 170 species of terrestrial isopods are known from Brazil, 29 of which are recorded from cave environments (Souza-Kury, 1993; Souza et al, 2006; 2010; 2015; CamposFilho et al, 2014; 2015)
Summary
The genus Trichorhina Budde-Lund, 1908 in Brazil includes 22 described species, four of which occur in caves. Thirteen species are known from the state of Paraná, but none of them was recorded from caves. In the present work the first cave-dwelling species of Trichorhina from the state of Paraná is described.
