PRINCE EDWARD ISLAND: Queens Co.: St. Patricks, 18.VIII.2002, C.G. Majka, along stream, (1, CGMC).
Atheta dadopora is newly recorded on Prince Edward Island ( Fig. 5). It has previously been recorded from Rhode Island, Pennsylvania, New York, Newfoundland, New Brunswick, and Nova Scotia ( Gusarov 2003, Klimaszewski et al. 2005; Majka and Klimaszewski 2008). It is widely distributed across the Palaearctic region eastward to China and Japan ( Smetana 2004a) and is found in decaying fungi, under cow dung, and fallen leaves (Burakowski et al. 1981). Although Gusarov (2003) listed it as an adventive Palaearctic species newly recorded in North America, its zoogeographic status is still unclear. It is possible that it could be Holarctic in distribution. It is provisionally included in this account as a Palaearctic species. The earliest records are from Casey (1910) from specimens collected in New York, Pennsylvania, and Rhode Island ( Gusarov 2003).
