Atheta klagesi is newly recorded in Alberta, British Columbia, New Brunswick, Nova Scotia, Ontario, and Prince Edward Island. In the Maritime Provinces it has frequently been recorded in old-growth and mature red spruce ( P. rubens) forests in decomposing mushrooms, on bracket fungi, and in compost. In Québec it was recorded in yellow birch ( B. alleghaniensis) forests by Klimaszewski et al. (2007b).
