Abstract

The Nearctic species of the genus Duta are revised. Two new species are described: D. foveolata (Canada, USA) and D. policeps (Canada, USA). Duta virginiensis (Ashmead), new combination, is shown to be widely distributed in the Western Hemisphere, extending to the New World tropics. A diagnosis of Duta and a key to the Nearctic species are given. The impact of environmental degradation on the frequency of Duta species in North America is discussed.

Résumé

Les espèces néarctiques du genre Duta ont fait l’objet d’une révision. Deux nouvelles espèces sont décrites : D. foveolata (Canada, É.-U.) et D. policeps (Canada, É.-U.). Duta virginiensis (Ashmead), nouvelle combinaison, s’est avéré très répandu dans l’hémisphère occidental et atteint même les tropiques du Nouveau Monde. On trouvera ici la diagnose de Duta ainsi qu’une clé d’identification des espèces néarctiques. L’impact de la dégradation de l’environnement sur la fréquence des espèces de Duta en Amérique du Nord est évalué.
