Distribution. This species is present mainly in the northern Mexico, in the states of Chihuahua and Sonora, in the Sierra Madre Occidental and Chihuahuan biogeographic provinces ( Morrone et al. 2022). There is a questionable record of one male from Colorado, United States ( Fig. 16 View FIGURE 16 ). Altitudinal range: 19 to 1511 m.

Etymology. This species is dedicated to Dra. Danuncia Urban , taxonomist and melittologist from Brazil, at Universidade Federal do Paraná, who contributed to the knowledge of Neotropical bees, especially Eucerini and Anthidiini .

Comments. In males, the DBP on frons can vary from 0.25 to 0.20 DOP, as well as in the DOP on T3. The males of this species are the most distinct ones among the genus by having tubercles on carinae on outer surface of mandible, and gonostylus, with subquadrate tips with tuft of simple and hooked hairs. Females of this species differ from H. micheneri as well by having usually more orangish hairs in tuft of dorsolateral angles of pronotum, while in H. micheneri hairs are usually whitish to yellow.
