Pronotum transverse, narrowing in front, anterior margin convex and posterior margin undulate. Tympana on both sides of fore tibiae and the outer one larger than inner one, hind tibia with three pairs of dorsal spurs and five apical spurs. Tegmen with pubescence and oblique long tudinal veins on dorsal filed ( Fig.5 View FIGURES 5 – 8 ), wings developed. Lateral branch of genitalia with 2 spines at apex ( Figs.7–8 View FIGURES 5 – 8 ).

Female. Tegmen with regularly longitudinal veins on the dorsal field, transverse veinlets more scarce ( Fig.6 View FIGURES 5 – 8 ). Ovipositor feebly curved, apical valves occupying half the total length, apex finely denticulated.

Etymology. The new specific name is derived from the two spines at each genitalia branch.

Discussion. This species resembles A. (A.) oedemeroides ( Walker, 1871) , but can be separated from it by coloration, veins of tegmen of male and the shape of male genitalia.
