Diagnosis

Females of this species have the basal elevation of the labrum orbicular and both sexes have the portion of mesepisternum anterior to mesepisternal groove punctate ( A. aurinasis subgroup). This is the only species with well-developed preoccipital carina forming a lamella, as thick as 0.7× OD on females and 1.5 OD on males. Both sexes have the surface of mesepisternum anterior to mesepisternal groove punctate; and the lower paraocular area contiguously punctate. Females have the posterior surface of metapostnotum without carinae or rugae; the hypostomal carina with a slight rounded prominence anteriorly; and the lateral teeth of clypeus projecting ahead of clypeal border. Males have the S5 with a glabrous patch medially; the hind femur without green reflection; and the metapostnotum entirely carinate-rugulose.

Head. Labrum basal surface light brown; basal elevation well defined, orbicular. Mandible mostly dark brown, medially light brown; distance between base and apical tooth about 3× mandibular basal width.

Supraclypeal area golden; upper portion contiguously punctate, becoming sparser (I <1.5 PD) near epistomal suture. Lower paraocular area golden; contiguously punctate near antennal socket; sparse setae with about 2 OD, shorter decumbent setae in between. Frons green with golden reflection; crowded punctures medially. Preoccipital carina as thick as 0.7 OD laterally. Gena golden. Post-gena punctate-striate, becoming microreticulate near hypostomal carina; with sparse setae <3 OD. Hypostomal carina very low, <0.3 OD, anteriorly with a slight rounded prominence. Mesosoma. Dorsolateral angle of pronotum obtuse in dorsal view. Fore leg coxa to femur black, with faint green reflections, tibia and tarsus yellow. Mesoscutum golden with copper reflection; anterior portion contiguously punctate, becoming sparser (I <PD) posterior to median line, disc smooth among punctures. Scutellum golden; sublateral surfaces with I <PD, smooth among punctures. Mesepisternum green with golden reflection; contiguously punctate anterior to mesepisternal groove, the remainder of lateral surface with I <0.5 PD, smooth among punctures, with well-defined punctures at mid height right after mesepisternal groove. Mid leg coxa to femur black, tibia and tarsus yellow. Metanotum green with golden reflection. Metepisternum green with golden reflection; with I <0.5 PD. Hind leg coxa green, trochanter and femur black, tibia and tarsus yellow. Metapostnotum almost as long as scutellum; basally with radiating carinae, becoming microreticulate to rugulose posteriorly. Propodeum green with golden reflection; contiguously punctate near metepisternum; posterior surface less than 1.5× higher than wide between lateral carinae. Metasoma. T1 mostly green with golden reflection, dorsally dull, apical dark band with 1.5 OD; weakly punctate on disc, lateral surfaces with tiny punctures (I <1.5 PD); anterior surface with dense tomentose setae among long setae. T2–4 mostly green with golden reflections; with weak and dense punctation. T5 black. S1 without median elevation. S1–6 dark brown, becoming lighter apically; S4 and S5 with long setae (> 3 OD) on posterior half.
