Abstract

Rudolfina digitata sp.nov. (Diptera, Sphaeroceridae, Limosininae) is described from the Yukon and Alaska and from alpine tundra in Alberta, Wyoming, Colorado, New Mexico, and New Hampshire. This distribution is discussed with respect to the hypothesis that these areas are postglacial refugia for arctic and subarctic species.

Résumé

Rudolfina digitata sp.nov. (Diptera: Sphaeroceridae: Limosininae) a été signalée à partir du Yukon et de l’Alaska et de la toundra alpine en Alberta, Wyoming, Colorado, New Mexico et New Hampshire. Cette distribution a été discutée en tenant compte de l’hypothèse que ces régions ont été les refuges post-glaciaux des espèces arctiques et subarctiques.
