DISTRIBUTION (Map 7) UNITED STATES: Arizona; MEXICO: south at least to Oaxaca and Morelos. SPECIMENS EXAMINED UNITED STATES, ARIZONA: Santa Cruz Co.: Upper White Rock Campground, Pena Blanca Lake( 31.39 ° N 111.08 ° W), 1200 m ( GCSC, LACM); Nogales, on sidewalk ( USNM). MEXICO, OAXACA: 14.5 km S Ocotlan, 1500 m( GCSC, WPMC). MORELOS: La Luz Tetecala( WPMC).
DISCUSSION This rather large distinctive species is only rarely encountered in the United States and its principal range lies in Mexico and Guatemala. As discussed above, we believe that N. mandibularisis the likely male of N. melanocephalus, but it is also possible that N. mandibulariscould be the opposite sex of N. graciellae. One foraging raid of N. melanocephaluswas observed. It occurred in full daylight and the workers were taking a variety of small arthropods (B. V. Brown, pers. comm).
