Forty years later: Distribution of the introduced Heath Snail, Xerolenta obvia, in Ontario, Canada (Mollusca: Gastropoda: Hygromiidae)

Abstract

Xerolenta obvia is a Central European land snail that has been introduced to Ontario, Canada, where it was first recorded in the literature in 1975 from a single population at Bethany (City of Kawartha Lakes). Over the four decades since that publication, additional records have been found clustered near Bethany, within the City of Kawartha Lakes, neighbouring Peterborough and Northumberland counties, as well as the Regional Municipality of Durham. Two distant sites are also now known, one in rural Ottawa (southeastern Ontario), and one at Windsor, Essex County (southwestern Ontario).
