Distribution. This species is present mostly in the center of Mexico, in areas with tropical dry forest and in the mountains in ecotone with pine-oak forest. There are records from the Sierra Madre Occidental, from Chihuahua to Guerrero, and it is endemic to Mexico (Fig. 26). Altitudinal range: 91 to 2230 m.
Etymology. This species is dedicated to the memory of Nora Patricia López, an environment biologist who worked in the protection of red Guacamayas (Ara macao), a species with high extinction risk in Chiapas, Mexico. She is one of the many environmentalists murdered for their activism on behalf of biodiversity protection in Latin America.
Comments. This species is abundant in collections. Females present variation in the size of tubercles on apical margin of clypeus. Females punctures on T3 varies slightly on size, but always large, also varies on shape from rounded to the more usual horseshoe-shaped. Males present variation in hairs of clypeus, on some long enough to cover low margin, and on others shorter, showing a few smaller hairs in the middle of apical margin.
