Taxonomic Comments
Originally described as P. blandii by Morse (1965). The use of the spelling "blandi" by Turgeon et al. (1998) appears to be a misspelling.

Range Extent20,000-200,000 square km (about 8000-80,000 square miles)
Number of Occurrences81 to >300
Rank Reasons
Range includes the American southwest centered upon much of New Mexico but also eastern Arizona, western Texas, south-central Colorado, and southwestern South Dakota (Nekola and Coles, 2010) with a questionable record from Alberta (Pilsbry, 1948).
Range Extent Comments

Occurrences Comments
This species seems to have been uniquely recorded from drift of the Red Deer River, east of Red Deer, in Alberta (Pilsbry, 1948; Leptizki, 2001) based on the original record in Taylor (1895). It was recently documented in 3 of 82 soil samples and 6 area spot searches of Wind Cave National Park, South Dakota, in 2002 (Anderson, 2005).
Ecology & Habitat

Habitat

East of the Rockies, populations of dwarfed individuals are occasionally found in xeric juniper savanna and mesic mixed conifer forest. In the mountains they occur in leaf litter accumulations in mid to high elevation oak, pine, fir, and spruce forest, becoming especially abundant in aspen groves (Nekola and Coles, 2010).
