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)GoogleMaps  ; 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. mandibularis  HNS  is the likely male of N. melanocephalus  HNS  , but it is also possible that N. mandibularis  HNS  could be the opposite sex of N. graciellae  HNS  .

One foraging raid of N. melanocephalus  HNS  was observed. It occurred in full daylight and the workers were taking a variety of small arthropods (B. V. Brown, pers. comm).
