Distribution of Strobilops aeneus Pilsbry, 1926, in Canada, with two new Ontario records (Mollusca: Gastropoda: Strobilopsidae)

Abstract

The geographic distribution of Strobilops aeneus Pilsbry, 1926, a rare species in Canada, is reviewed and all known records are mapped. Two recent records, the only ones since 1941, are reported from the province of Ontario. One of these records represents a small range extension ca. 85 km north of the closest previous site. Specimens identified as S. aeneus from Ontario, New Brunswick, and Nova Scotia were re-examined and found to be another species.
