Nitidulidae and Kateretidae (Coleoptera: Cucujoidea) of the Maritime provinces of Canada.: I.: New records from Nova Scotia and Prince Edward Island

The Nitidulidae and Kateretidae of the Maritime provinces of Canada are surveyed. Forty-eight species are now known to occur in the region. Twenty-six are newly recorded in Nova Scotia and nine are newly recorded on Prince Edward Island. One Palearctic species, Soronia grisea (L.), is reported for only the second time in North America. Six other nonnative species have been intercepted. One new synonym, Glischrochilus sanguinolentus sanguinolentus (Olivier, 1790) (= Glischrochilus sanguinolentus rubromaculatus (Reitter, 1873) syn. nov.), is designated. Cape Breton and Prince Edward Island appear to have a depauperate fauna, perhaps reflecting an island-related diminution of species, a comparative lack of collection effort, or a combination of both. An examination of the Nova Scotia fauna indicates several distribution patterns within the province. Introduced species constitute a sizeable component of the region's fauna, with four new introductions being reported here.
