Abstract
A new species of fossil isopod, Palaega goedertorum, is described from late Eocene to early Miocene rocks of the Twin River Group, the Astoria Formation, and unit B of Wolfe and McKee (1968) in the state of Washington. These fossil forms are similar to living forms referred to the genus Bathynomus A. Milne-Edwards, 1879; hence, Bathynomus is considered a junior subjective synonym of Palaega Woodward, 1870. Since extant species of Palaega are known only from bathyal habitats, these occurrences tend to corroborate the deep-water paleoenvironmental setting of these rock units. This is the first report of Palaega from the eastern Pacific region.Keywords
