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). This species is more similar to A. morrae in having the mesoscutum with punctures with similar sizes only. Both sexes of A. laevinota sp. nov. can be diagnosed by the relatively sparse punctation, especially on the surface posterior to median line on mesoscutum (I> 0.5 PD on females and I> PD on males). Males also have the propodeum lateral surfaces smooth among punctures, and the paraocular area densely punctate near antennal socket, while in similar species this region is contiguously punctate.

Description

Female. Measurements. Distance between eye notches: 1.5; head length: 1.6; clypeus width: 0.5; clypeus length: 0.4; clypeoantennal distance: 0.3; clypeus ocellar distance: 1; intertegular distance: 1.3; T1 width: 1.6; T2 width: 1.9; body length: 7. 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 golden with copper reflection, apical dark band as long as 1.5 OD; with shallow punctures, contiguously punctate; lateral teeth prominent. Supraclypeal area golden with copper reflection; upper portion densely punctate, becoming sparser (I <PD) near epistomal suture. Lower paraocular area mostly golden with copper reflection; contiguously punctate near antennal socket; sparse setae with about 1.5 OD, shorter decumbent setae in between. Frons green with golden reflection; crowded punctures medially. Preoccipital carina as thick as 0.3 OD laterally. Gena golden with copper reflection. Post-gena striate, becoming microreticulate near hypostomal carina; with sparse setae <3 OD. Hypostomal carina very low, <0.3 OD, anteriorly with a slightlly pointed prominence. Mesosoma. Dorsolateral angle of pronotum obtuse in dorsal view. Fore leg coxa to femur dark brown, coxa and femur with faint green reflections, tibia and tarsus light brown. Mesoscutum green with golden and copper reflections; anterior portion rugulose, becoming punctate on disc (I <PD). Scutellum green with golden reflection; entirely densely punctate, I <0.5 PD. Mesepisternum green with golden reflection; rugose anterior to mesepisternal groove, the remainder of lateral surface with I <0.5 PD, smooth among punctures, with shallow punctures at mid height right after mesepisternal groove. Mid leg coxa to femur dark brown, tibia and tarsus light brown. Metanotum green with golden reflection. Metepisternum green with golden reflection; contiguously punctate. 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 golden with copper-red reflection, apical dark band with 0.5 OD; entirely punctate, I <2 PD; anterior surface with dense tomentose setae among long setae. T2–4 mostly golden with copper-red reflections; with weak and dense punctation. T5 dark brown. S1 without median elevation. S1–6 dark brown, becoming lighter apically; S4 and S5 with long setae (> 3 OD) on posterior half.
