Abstract

Subspeciation in the circumpolar Nephrotoma lundbecki is discussed for a population from south of the Laurentide Ice Sheet, described here as N.l. alexanderi. For 18 nearctic Nephrotoma species new distribution records are presented, mainly from the northern Nearctic, adding considerably to our knowledge of the distribution of these species. Included is the second nearctic record of the palaearctic species Nephrotoma cornicina (L.).

Résumé

On discute de sous-spéciation pour une population de l’espèce circon-polaire Nephrotoma lundbecki provenant du sud de la calotte glaciaire laurentienne, et décrite ici comme N.l. alexandri. On présente les nouvelles distributions établies des 18 espèces de Nephrotoma, surtout pour le Néarctique boréal, augmentant ainsi de beaucoup notre connaissance de la répartition de ces espèces. On trouvera la seconde mention néarctique de l’espèce paléarctique Nephrotoma cornicina (L.).
