Identification

This species can be easily recognized by the thick petiole with a blunt apex, as seen in profile. Additionally it is pale brown with a slightly darker gaster. The propodeum is low, about the same level as the lowest point (posterior edge) of the mesonotum. The region between the two faces is broadly rounded. The metasternal process is poorly developed; there are few erect hairs, which are restricted to the clypeus, dorsum of the head and dorsum of the gaster. (Mackay and Mackay 2002)

Habitat

In New Mexico (Mackay and Mackay 2002) - This species occurs in habitats that include a variety of arid, semi-arid and pine forest types.

Biology

Nevada, Wheeler and Wheeler (1986) - This species has been found only in the southern and western parts of the state. We have 29 records from 20 localities; 4,200 ft.-6,500 ft. One record is from a Sarcobatus Subclimax in the Hot Desert, 3 from the Cool Desert (2 from disturbed habitats), while the majority (19) are from the Pinyon-Juniper Biome. Five nests were under stones, 1 under dead wood; of the exposed nests 5 were surmounted by messy piles of excavated soil and 7 by craters 7-22 cm in diameter with entrances 15-20 mm in diameter.
