Description of a new genus and species of crayfish from the Eocene McAbee beds in southern British Columbia, Canada, marks the first occurrence of Parastacoidea Huxley, 1879, in the Northern Hemisphere. The superfamily is widely distributed in modern aquatic environments in the Southern Hemisphere, except in Africa and Antarctica, as well as in Australia, New Zealand, and South America in the fossil record. The occurrence of a single species in the Eocene of North America suggests a Cretaceous or Paleogene dispersal from the Southern Hemisphere through eastern Asia. Remarkable preservation of the specimens reveals traces of muscles, the endophragmal skeleton, and the intestinal tract.
