Terrestrial isopods (Crustacea, Oniscidea) from Rocas Atoll, northeastern Brazil

Four Oniscidea species are recorded from Rocas Atoll, State of Rio Grande do Norte: Olibrinus antennatus Budde-Lund, 1902, Littorophiloscia culebrae (Moore, 1901), Niambia squamata (Budde-Lund, 1885) and Porcellionides pruinosus (Brandt, 1833). These are the first records of terrestrial isopods from Rocas Atoll. Littorophiloscia culebrae is recorded for the first time from Brazil. Niambia atracheata (Schmalfuss & Ferrara, 1978) is considered to be a junior synonym of N. squamata.
