Faunal Analysis and Discussion
The Aleocharinae fauna of eastern Canada is analyzed for geographic affiliation. Only 4.9–5.9% of the fauna is Holarctic but 11.3% of species are adventive and are of Palaearctic origin. The number of species remaining to be discovered in eastern Canada as a whole and in each of its jurisdictions was estimated using simple calculations. At least 70–75 additional species are expected to be found in the region. The fauna of PE is the most poorly known as only 24 species out of an estimated 137 are yet documented. Additional surveys and taxonomic research are needed to fully document the eastern Canadian fauna. Regions and habitats that are particularly poorly sampled and genera that are poorly studied taxonomically are discussed.
