Range Description

This species occurs in three disjunct population units, corresponding to subspecies S. e. aureus found in southwestern Montana and adjoining Idaho; S. e. elegans in northern Colorado, southern Wyoming, extreme western Nebraska, and extreme northeastern Utah; and S. e. nevadensis in north-central Nevada, southwestern Idaho, and possibly extreme southeastern Oregon. However, only one population of S. e. nevadensis still exists in Idaho, it appears to be extinct in Oregon, and it occurs in only a few places in Nevada.
