This paper treats 13 species of the subgenus Microdota Mulsant & Rey of Atheta Thomson and 3 species of the genus Clusiota Casey in Canada and Alaska. We report here 4 species new to science, and 3 new provincial records. The following species are new to science: A. (M.) curtipenis Klimaszewski & Webster, sp. n., A. (M.) formicaensis Klimaszewski & Webster, sp. n., A. (M.) macesi Klimaszewski & Webster, sp. n., and Clusiota grandipenis Klimaszewski & Webster, sp. n. The new provincial records are: A. (M.) pseudosubtilis Klimaszewski & Langor, new to AB, and A. (M.) subtilis (Scriba), an adventive Palaearctic species new to North America, first reported in LB and NB. The two Clusiota Casey species are reviewed, and their distribution is revised. A female C. impressicollis was discovered in Ontario and is illustrated here for the first time. A key to all Canadian species of the subgenus Microdota and genus Clusiota are provided. Atheta (Microdota) holmbergi Bernhauer and A. (M.) alesi Klimaszewski & Brunke are transferred here to the subgenus Dimetrota Mulsant & Rey.

Plain Language Summary

In this article, the researchers took an inventory of of 13 insect species belonging to the Microdota and Clusiota genera (Coleoptera order) that are present in Canada (Alberta, British Columbia, New Brunswick and Ontario) and the United States (Alaska). This article also includes identification keys, photographs, habitat data and distribution maps. For some of these species, it is the first scientific description of the species or the first reporting of the species’ presence in Canada.

Taxonomy is the science of classifying living things. Insects are grouped into various orders, which subdivide into families, genera and species. The taxonomic approach is particularly used in biodiversity studies and in studies that measure the impact of anthropogenic activities on forest ecosystems.
