Males can be diagnosed on the basis of a unique conformation of the tibia leg I, spination pattern which comprises numerous spines on the prolateral and distal surfaces (Figs 142-144). This spination pattern is most similar to the Channel Islands species

is known only from a single specimen taken from the type locality in Arizona, Cochise Co., Portal (Map 1). Despite extensive collecting efforts in the area female burrows have never been observed. Based on the paucity of specimens, the species may be quite rare.
