Lynn T. Lesko Janet W. Reid 2003 <i>Moraria hudsoni</i> n. sp. is described from Trails End Bay in Lake Michigan and Prentiss Bay in Lake Huron, Michigan, USA. The new species differs from its congeners in chaetotaxy, body ornamentation, and other characters. We review published records of members of <i>Moraria</i> from North and Central America; no species is known from South America. Species of this genus have been found in the mountains of southern Mexico, Guatemala, and Honduras, but none of these has been validly described. In North America, eight species have been recorded from Alaska, Canada, and the conterminous USA as far south as North Carolina. We report new geographical records of <i>M. affinis</i> from Virginia, and of both <i>M. cristata</i> and <i>M. virginiana</i> from Maryland and Virginia. We provide a tabular key to aid in identification of the named species of <i>Moraria</i> in North America. application/pdf 10.11646/zootaxa.205.1 en Magnolia Press A new species of Moraria (Crustacea: Copepoda: Harpacticoida) from the Laurentian Great Lakes article
