Males (Fig. 197) can be diagnosed on the basis of a unique conformation of the distal most spination pattern of tibia I, which consists of 2-3 long spines that typically do not overlap (Fig. 198). This spination pattern is most similar to

is known from Anza-Borrego Desert State Park in San Diego County within the Colorado Desert (Map 21). Male specimens have been collected during October. Female burrows can often be found in sandy banks and washes during the winter months when individuals excavate and presumably extend their burrows, creating a telltale mound at the burrow entrance.
