Abstract
Two pairs of bopyrids collected on Easter Island, from the hermit crab Calc inus imperialis Whitelegge, belong to the genus Pseudionella Shiino (=Pseud asymmetrione Adkinson & Heard, new synonymy) and are described as P. akuaku n. sp. This is the first record of any bopyrid isopod from Easter Island a nd the first Pseudionella known to parasitize hermit crabs of the genus Cal cinus. A review of the species of Pseudionella, with keys to males and fema les, is provided and includes a significant range extension for P. deflexa Bourdon.
