This species, known only in the male, is similar to rhodognatha, differing chiefly in the entirely red abdomen and the largely red legs. The structure and punctation of the two species are about the same.
Male: Face broader than long, densely covered with white pubescence; inner margins of eyes converging below, less curved than in rhodognatha; mandibles reddish except basally and apically, apical tooth long; cheeks much narrower than eyes, seen from side; tegulae testaceous; legs red, fore and middle femora and coxae suffused with black; abdomen yellowish red; lateral teeth of sixth tergite rather broad; median teeth of sixth tergite longer than basal width, concavity between them longer than a semicircle.
This species occurs in Arizona and New Mexico. The Arizona record is based on a specimen in the National Museum, without exact locality data
