range Known only from several Arizona collections made by Stefan Cover in the Chiricahua Mts., 1550-1650 m; Pajarito Mts., Santa Cruz Co., 1110 m; and Patagonia Mts., 1420 m.
Biology The type colony was found nesting in soil beneath a pat of dried cow dung in a grassy, grazed meadow with scattered juniper (Stefan Cover). Other colonies were found by Cover beneath a rock in a grassy juniper flat, in a cryptic soil nest on a rocky hillside covered by acacia-opuntia scrub, and under a rock in an overgrazed, grassy creek valley.
