Popis: Augochlora (Oxystoglossella) thalia Smith, 1879 (Figure 14A) Augochlora thalia Smith, 1879. Lectotype female (BMNH) from Brazil, Amazonas, São Paulo de Olivença, is presently designated to stabilise the taxonomy of the species. Examined through photographs. Halictus ardens Vachal, 1911. Holotype female (MNHP) from Peru, ′ Callanga ̍. Examined through photographs. New synonym. Diagnosis Females of this species have the basal elevation of labrum orbicular and both sexes the portion of mesepisternum anterior to mesepisternal groove mostly covered with coarse rugae and gena and post-gena striate (A. morrae subgroup). Augochlora thalia have the mesoscutum disc with punctures of two diameters and is more similar to Augochlora erubescens, from which it can be separated by the anterior portion of mesoscutum rugulose and the preoccipital carina produced, and to Augochlora antonita, from which it can be separated by head and mesosoma with abundant long yellowish setae. Males and most female specimens have strong copper-red reflections on the head, on the dorsal portion of mesosoma and on metasomal terga. Comments The holotype of Augochlora thalia does not have strong copper red reflections on mesoscutum like other examined specimens, but the remaining diagnostic features are present. We infer that the colour of the holotype results from variation or preservation artefacts. The type locality of Halictus ardens, ′Callanga̍, refers to an ancient outpost at the foothills of the Andean mountains on the region of Cusco, as noted by previous authors (Engel and Rasmussen 2013; Melo 2016). The locality was mistakenly interpreted as related to Lima by Moure (2012). Description Female. Measurements.

Head. Labrum basal surface light brown; basal elevation well defined, orbicular. Mandible mostly light brown, base and apex dark brown; distance between base and apical tooth about 3× mandibular basal width. Clypeus disc mostly copper, apical dark band as long as 1.5 OD; with shallow punctures, contiguously punctate; lateral teeth prominent. Supraclypeal area copper; upper portion densely punctate, becoming sparser (I Mesosoma. Dorsolateral angle of pronotum obtuse in dorsal view. Fore leg coxa, trochanter and femur black, with weak green reflections on coxa and femur, tibia and tarsus light brown. Mesoscutum disc entirely copper, edges green with golden reflections; anterior portion rugulose, becoming contiguously punctate posteriorly, with sparse larger punctures among tiny ones.
