Three new species of fossil decapod crustaceans are reported from the Early Cretaceous (Albian) Hudspeth Formation of central Oregon. Dromiopsis oscari n. sp. represents the oldest species of Dromiopsis in North America. Glaessnerella yamoori n. sp. represents the f rst report for the genus outside of Europe. Eodorippe connori n. sp. represents the oldest record for the genus. Finally, Hoploparia riddlensis FELDMANN, 1974 is reported from the Hudspeth Formation, enlarging the stratigraphic range of this species limited to date to the Hauterivian of the Days Creek Formation (Riddle, Douglas Co., Oregon).
