Abstract

In Canada, the Squat Duskysnail, Lyogyrus granum, is an apparently rare freshwater hydrobiid. We document putative L. granum to be widespread throughout the Hampton Marsh, New Brunswick, with densities sometimes exceeding 150 snails/m2 on substrates ranging from vegetated organic detritus over mud, to sparsely-vegetated cobble/sand lakeshore. That our identification of L. granum from Hampton Marsh remains tentative, in spite of large samples, emphasizes the need for detailed taxonomic study of any putative L. granum populations in Canada. Such study will be necessary before the true conservation status can be determined for this and any related taxa, as yet unrecognized in Canadian material.
