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 species can be separated from similar species by the posterior half of S4 with short setae (<1.5 OD), and posterior half of S5 with scattered long setae among short setae (<3 OD). Another diagnostic feature is the hypostomal carina forming a tooth anteriorly. Males are not known.

Description

Female. Measurements. Distance between eye notches: 1.5; head length: 1.8; clypeus width: 0.5; clypeus length: 0.4; clypeoantennal distance: 0.3; clypeus ocellar distance: 1.1; intertegular distance: 1.1; T1 width: 1.6; T2 width: 1.8; body length: 7.5. Head. Labrum basal surface brown; basal elevation well defined, orbicular. Mandible mostly dark brown, medially light brown; distance between base and apical tooth about 4× mandibular basal width. Clypeus disc mostly green with golden reflection, apical dark band as long as OD; with shallow punctures (I <PD); lateral teeth prominent. Supraclypeal area golden; upper portion contiguously punctate, becoming sparser (I <PD) near epistomal suture. Lower paraocular area green with golden reflection; contiguously punctate near antennal socket; sparse setae with about 2 OD, shorter decumbent setae in between. Frons green with golden reflection; contiguously punctate medially. Preoccipital carina as thick as 0.3 OD laterally. Gena green with golden reflection. Post-gena striate, becoming microreticulate near hypostomal carina; with sparse setae <3 OD. Hypostomal carina very low, <0.3 OD, anteriorly with a strong prominence, forming a pointed tooth. Mesosoma. Dorsolateral angle of pronotum obtuse in dorsal view. Fore leg coxa to femur black, with faint green reflections, tibia and tarsus yellow. Mesoscutum green with golden reflection; anterior portion densely punctate, becoming sparser (I <PD) posterior to median line, disc smooth among punctures. Scutellum green with golden reflection; 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 <PD, smooth among punctures, with shallow punctures at mid height right after mesepisternal groove. Mid leg coxa and trochanter black, femur dark brown, tibia and tarsus yellow. Metanotum green with golden reflection. Metepisternum green with golden reflection; with I <PD. Hind leg coxa green, trochanter black, femur brown, tibia and tarsus yellow. Metapostnotum as long as scutellum; basally with radiating carinae, becoming microreticulate 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, discs darkened; with weak and dense punctation. T5 black. S1 without median elevation. S1–6 dark brown, becoming lighter apically; S4 and S5 mostly with tiny setae on posterior half, longer setae <3 OD.
