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). Females of this species are similar to A. aurinasis and A. eucnemis and can be separated from both by the posterior surface of metapostnotum covered with rugae or microreticulate, never smooth, and basal surface of labrum dark brown. The males have the metapostnotum entirely carinate-rugulose, most similar to A. lamellata sp. nov. but the preoccipital carina is not lamellate and the dorsolateral angle of the pronotum is obtuse.

Description

Female. Measurements. Distance between eye notches: 1.2; head length: 1.5; clypeus width: 0.4; clypeus length: 0.4; clypeoantennal distance: 0.2; clypeus ocellar distance: 0.9; intertegular distance: 0.9; T1 width: 1.2; T2 width: 1.5; body length: 6. Head. Labrum basal surface dark 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 green with golden reflection; upper portion contiguously punctate, becoming sparser (I <PD) near epistomal suture. Lower paraocular area green; 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 0.3 OD laterally. Gena green with golden reflection. 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 light brown. Mesoscutum green; anterior portion contiguously punctate, becoming sparser (I = 0.5 PD) on disc, smooth among punctures. Scutellum green; sublateral surfaces with I <PD, smooth among punctures. Mesepisternum green; with crowded punctures 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 dark brown, tibia and tarsus light brown. Metanotum green. Metepisternum green; with I <0.5 PD. Hind leg coxa green, trochanter and femur dark brown, tibia and tarsus light brown. Metapostnotum almost as long as scutellum; entirely carinate-rugose. 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.
