A collection of eight species of terrestrial isopods from lava and cave sites on Ascension Island is described. Two species, Niambia longiantennata (Platyarthridae) and Elumoides coecus (Eubelidae), are described as new. Atlantoscia alceui Ferrara and Taiti (Philosciidae) is considered to be a junior synonym of A. floridana (Van Name) and the genus Ocelloscia Schultz and Johnson of Atlantoscia Ferrara and Taiti. At present the oniscidean fauna known from Ascension Island consists of 13 species.
