Ceutorhynchus howdenae Korotyaev and Anderson, new species (type locality: Canada, North-Western Territories, Fort McPherson) is described. This is the second subarctic species of Ceutorhynchus Germar endemic to North America. It is related to the xerophilous species Ceutorhynchus mutabilis Dietz, to which it is also most similar. The more southern xerophilous C. mutabilis is associated with Erysimum L. (Brassicaceae), and it is possible that C. howdenae uses a host in the same genus, almost certainly in the same family.
