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.

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.
