Abstract

Seven Plains Minnows, Hybognathus placitus, Family Cyprinidae, were collected on 11 June 2003 from Morgan Creek, in Grasslands National Park, Saskatchewan, Canada. This collection is the first record of the species in Canada and extends the northern distribution limit of the species. Of 95 Hybognathus spp. collected at the site, only eight specimens were retained for positive identification because of the uncertain status of two conspecifics, the Western Silvery Minnow, H. argyritis, and the Brassy Minnow, H. hankinsoni, in Saskatchewan. Our findings should stimulate additional sampling to assess the identification and status of Hybognathus spp. in southwestern Saskatchewan. Accurate field identification of Hybognathus spp. remains an issue and collection of all specimens is recommended to accurately identify members within the genus.
