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). It can be separated from the remaining Oxystoglossella by the metapostnotum not covered with carinae posteriorly, smooth, its basal surface depressed; T1 disc with copper reflections,shiny, punctures well defined; hypostomal carina anteriorly with a strong rounded projection on females and raised as a translucent lamella as high as 0.8 OD on males. The raised hypostomal carina can be found in A. cymatoides , but this species has the anterior surface of the mesoscutum disc rugulose, a characteristic not found in A. almeidai sp. nov.

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. Clypeus disc mostly golden, 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 <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; contiguously punctate 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 low (0.5 OD), anteriorly with a strong 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 densely 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 and trochanter black, femur brown, 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 black, femur to tarsus yellow. Metapostnotum almost as long as scutellum; basally with radiating carinae, becoming smooth posteriorly. Propodeum golden with copper reflection; densely punctate near metepisternum; posterior surface less than 1.5× higher than wide between lateral carinae. Metasoma. T1 mostly golden with green and copper reflections, dorsally shiny, apical dark band (= OD); sparsely punctate on disc (I = 2 PD), lateral surfaces with tiny punctures (I = 3 PD); anterior surface with sparse tomentose setae among long setae. T2–4 mostly golden with green and copper reflections; sparsely punctate (I = 1.5 PD). T5 black. S1 without median elevation. S1–6 dark brown, becoming lighter apically; S4 and S5 with long setae (> 3 OD) on posterior half.
