Comments

The male holotype of Halictus pinacis has a ferruginous hind basitarsus, not yellow as in Oxystoglossella , and the head shape and body punctation agree with those of A. bractealis , recently transferred to Augochlora s. str. by Lepeco and Goncalves (2022). Vachal (1911, p. 50) separated H. pinaci s from H. bractealis based on T1 colouration, not entirely metallic on H. pinacis ; however, examining the holotypes images we suppose that this difference is due to particular specimen preservation, as seen in a series of other species, such as A. obidensis sp. nov.
