Comments.

The specimens form Ontario agree in most characteristics with British Columbian specimens of Atheta nescia except for the less robust antennae, particularly in males, and the median lobe in lateral view, with a slightly narrower tubus and more rounded apex (for illustrations of the genitalia of Atheta nescia see Figs 51-53 in Klimaszewski and Winchester 2002 under the synonymic name Atheta vancouveri Klimaszewski). The spermathecae of the two species are similarly shaped. Therefore we tentatively associate the Ontario specimens with Atheta nescia but more specimens are needed from a broader distributional range to fully establish their identity.

The Ontario specimens were captured in sparsely treed, open habitats including savannahs and an agricultural hedgerow. Similarly, the specimens of Atheta nescia collected in British Columbia were primarily collected in clear-cut forests ( Klimaszewski and Winchester 2002, as Atheta vancouveri ).
