The Cambrian olenid trilobite PelturaMilne-Edwards, 1840 is widespread in the Furongian strata of the Cambrian continents of Baltica and Avalonia, and has played a significant role in biostratigraphic zonations for both regions. Despite this importance, the genus is poorly known in Avalonian Canada. New collections from the Chelsey Drive Group on Cape Breton Island, Nova Scotia, yielded numerous sclerites of a new species, Peltura hutchinsoni sp. nov., that may also occur in the Parabolina lobata Zone of Baltica. Archival specimens from Sweden and Norway allow the revision of Peltura scarabaeoides (Wahlenberg, 1821) and Peltura acutidensBrögger, 1882, respectively.
