This data contains genetic sequences of crustaceans from the mitochondrial genome in support of the discovery and description of a new species of crustacean in Alaska, Eurycercus beringi. We carried out a detailed anatomical and genetical analysis of Holarctic crustaceans of the freshwater genus Eurycercus in order to understand the biodiversity and potential implications of recent environmental change and surface water loss in the Arctic. We described new species and revised the subgenus. The genus is an important source of food for fish, waterfowl, and wading birds. Eurycercus is also used in paleolimnology to reconstruct past environmental conditions. We aimed for thorough geographic coverage of subarctic and arctic Siberia, Greenland, Alaska and Canada. The genetic results support the revision of the genus Eurycercus and the novel species E. beringi.
