Abstract

Six new aleocharine species are described and illustrated from the Yukon and Alaska: Atheta (Dimetrota) cadeti Klimaszewski and Godin, sp. nov.; Atheta (Hypatheta) pseudomet lakatlana Klimaszewski and Godin, sp. nov.; Cypha inexpectata Klimaszewski and Godin, sp. nov.; Oxypoda yukonensis Klimaszewski and Godin, sp. nov., Oxypoda pseudoconvergens Klimaszewski and Godin, sp. nov.; and Clusiota antennalis Klimaszewski and Godin, sp. nov.Atheta (Rhagocneme) subsinuata (Erichson), known from the western Palaearctic region, was discovered in the Yukon and is reported in North America for the first time as an adventive species. Amischa tersa Casey is recorded from Canada and the Yukon for the first time. Twenty-four new records of aleocharine species from the Yukon are provided in addition to species described as new to science. One hundred and fifteen digital images of external and genital structures are provided for species identification.

Six nouvelles espèces d’aléocharinés du Yukon et de l’Alaska sont décrites et illustrées: Atheta (Dimetrota) cadeti Klimaszewski et Godin, sp. nov.; Atheta (Hypatheta) pseudometlakatlana Klimaszewski et Godin, sp. nov.; Cypha inexpectata Klimaszewski et Godin, sp. nov.; Oxypoda yukonensis Klimaszewski et Godin, sp. nov., Oxypoda pseudoconvergens Klimaszewski et Godin, sp. nov.; et Clusiota antennalis Klimaszewski et Godin, sp. nov.Atheta (Rhagocneme) subsinuata (Erichson), connue dans l’ouest de la région paléarctique, a été récoltée au Yukon et est mentionnée pour la première fois en Amérique du Nord comme espèce introduite. Amischa tersa Casey a été nouvellement découverte au Canada et au Yukon. Nous la considérons comme une espèce holarctique ou introduite en Amérique du Nord. Vingt-quatre nouvelles mentions d’espèces d’aléocharinés du Yukon sont présentées en plus des espèces nouvellement décrites pour la science. Cent quinze photographies des habitus externes et structures génitales sont présentées afin de faciliter l’identification.
