[Crustacea • 2017] Xangoniscus itacarambiensis • A New Amphibious Troglobitic Styloniscid (Isopoda, Oniscidea, Synocheta) from Brazil

Xangoniscus itacarambiensis
 Pereira, Souza & Ferreira, 2017


Xangoniscus (Styloniscidae, Synocheta, Isopoda) includes only two species, both occurring in Brazil. Here a new amphibious troglobitic species of this genus found at Olhos D’Água Cave, Northern Minas Gerais, Brazil, is described. Xangoniscus itacarambiensis sp. nov. differs from the congeneric species mainly due to the following characters: head well-detached from the first pereonite, second and third articles of antennula subequal in length, presence of six short aesthetascs in the antennula and reduced triangular lobe in the distal part of pleopod 2 endopod.

Keywords: Isopoda, Styloniscidae, Xangoniscus, Brazil
