Augochlora (Oxystoglossella) aurinasis (Vachal, 1911)

(Figure 1A)

Halictus aurinasis Vachal, 1911: 23, lectotype ♀ (MNHP) from Peru, Cuzco, Vilcanota. Subsequent designation by Moure & Hurd (1987: 271). Examined through photographs.

Diagnosis. Differently from A. iphigenia, females lack the well-developed tooth anteriorly on hypostomal carina and males have a yellowish band on clypeus apex. From A. mendax sp. nov. it differs in the lack of a tuberculate elevation on female S1 and on the long and parallel-sided hind basitarsus of the males. From A. morrae it can be separated by the punctate preepisternum, the anterior border of mesoscutum not rugulose and the glabrous patch medially on male S5, along with the microreticulate metapostnotum posterior surface in both sexes. On the females, the gena and postgena can be weakly striate, but never as strong as in A. morrae . A. aurinasis is also remarkable for the abundant golden reflections, which may turn into copper on the head.

Comments. For species redescription and additional notes see Lepeco & Gonçalves (2020).
