Elaphrus fuliginosus Say

Elaphrus fuliginosus is found in Alberta, Manitoba, Ontario, and Québec (www.gbif.org/species/ 1035539), although Bousquet (2012) notes the Alberta location is unexpected. Lindroth (1961) recorded E. fuliginosus from southern and eastern Ontario. This species is generally distributed below 50° north latitude in beach habitats where there is little vegetation and wet sandy soil (Goulet 1983). Here we report the first territorial records from Nunavut (Fig. 2h).

Six Blethisa species are known to occur in North America; three have previously been collected in Ontario’ s Far North ( Lindroth 1961). In our study, we found two species, B. julii and B. quadricollis . We did not collect the third northern Ontario species, B. hudsonica , which is far more widespread across northern Canada ( Lindroth 1961; Bousquet 2012).

There are two species of Diacheila in North America, D. arctica and Diacheila polita (Falderman, 1835) . Diacheila polita occurs exclusively in northwestern Canada and was not expected to be collected in Ontario’ s Far North. Diacheila arctica is an extremely northern species and is likely not often caught due to its short active period ( Lindroth, 1961; Elias 1992; Bourassa and Wood 2011). As well, fossilized specimens of D. arctica are recorded from northeastern Labrador, Nova Scotia, Switzerland, northeastern France, and Poland in numerous studies, indicating that it once had a more extensive range ( Elias 1982; Ponel 1995; Miller 1997; Kasse et al. 1999; Coope 2007).

Of the 19 species of Elaphrus that have been recorded in North America, eight are known to occur in northern Ontario. We collected five Elaphrus species in our study, but did not collect Elaphrus lapponicus Gyllenhal, 1810 , Elaphrus olivaceus LeConte, 1863 , and Elaphrus trossulus Semenov, 1904 .
