(Figs. 4–6C,D)
Diagnosis. The female of this species is very similar to A. acarinata. The body of A. mavricera sp. nov. is mostly dark green with some violet reflections on clypeus and supraclypeal area and black dorsal surfaces of terga (Fig. 4) while A. acarinata is bright green with some copper reflections. Also, A. mavricera sp. nov. punctation is sparser than on A. acarinata (i>2pd on lower paraocular and i>pd on mesoscutum). The male can be easily separated of A. acarinata by the dark body, including legs (Figs. 5 and 6D), compared with yellowish color of A. acarinata (Fig. 6A,B). The S4 is slightly bilobed (Fig. 6C) in the new species, while A. acarinata males have S4 strongly bilobed (Fig. 6A).
