Abstract

A new carabid species, Pterostichus (Melanius) castor, is described and characterized. The species appears to be restricted to beaver houses in eastern North America. The new species is closely related to P. ebeninus Dejean but can be distinguished from that species mainly by the form of the pronotum. Lindroth's key to Pterostichus of Canada is modified to include the new species.

Résumé

Une nouvelle espèce de Carabidae, Pterostichus (Melanius) castor, est décrite et caractérisée. L'espèce semble restreinte aux huttes à castor de l'est de l'Amérique du Nord. La nouvelle espèce est voisine du P. ebeninus Dejean mais se différencie de cette espèce en particulier par la forme du pronotum. Le tableau de détermination des Pterostichus du Canada par Lindroth est modifié afin d'inclure la nouvelle espèce.
