A beginner-friendly key to the spider families (Arachnida: Araneae) known from the Canadian Prairie Provinces (Alberta, Saskatchewan, and Manitoba).

The Canadian Prairie Provinces (Alberta, Saskatchewan and Manitoba) are home to species from 29 of the 45 spider families currently found in Canada. Here we provide a beginner-friendly dichotomous key to the spider families of the Canadian Prairies. The key includes numerous photos, line drawings, and simplified definitions of anatomical characters necessary for family-level identification. For each family we include an illustrated summary of important character states, a whole-body photo of an exemplar of the family, and number of species of the family currently reported from the Prairie Provinces.
