Abstract

The cave-living and monobasic fungus gnat genus Speolepta Edwards is reviewed with a description of the first Nearctic species, Speolepta vockerothisp. nov., from Canada (caves in Ontario and British Columbia) and the United States (Alaska). Its morphology, life history, and biology are documented and compared with the single European species Speolepta leptogaster (Winnertz). A further new species, Speolepta orientalissp.nov., is described based on a single male from northern Vietnam, representing the first record of this genus from the Oriental Region.

Résumé

Une révision du genre cavernicole Speolepta Edwards est proposée. Le genre est pour la première fois répertorié dans la région Néarctique avec la description de Speolepta vockerothisp.n. découvert à la fois au Canada (Ontario et Colombie Britanique) et aux États-Unis (Alaska). Des données sur la morphologie, le mode de vie et la biologie de cette espèce sont fournies. La description d'une seconde espèce nouvelle, Speolepta orientalissp.n., est basée sur un unique mâle collecté dans le nord Vietnam, ce qui constitue la première mention du genre dans la région Orientale.
