Atheta nigra is a Palaearctic species reported from across Europe, European Russia, Kazakhstan, North Korea and southern China ( Newton 2019). It is adventive in North America and New Zealand ( Newton 2019) and is here newly reported from Ontario. The new record from Ontario indicates that this species is far more widely distributed in North America than previously known.
