Holotype description. Head and thorax. Structural features of head and thorax much as described above for A. falcata sp. nov., except median length of crown approximately 9/10 interocular width and 1/2 transocular width, pronotum with posterior margin strongly concave, and forewings translucent. Color. Anterior dorsum (Fig. 26) dark brown to black with many irregular yellow spots, except disc of pronotum with green spots; apex of scutellum greenish-white. Forewing (Figs. 26–27) translucent, except small yellow markings and brown area at base; veins brown. Face (Fig. 27) dark brown to black; frons with three large yellow areas, two inferior and one superior. Lateral and ventral portions of thorax (Fig. 27) dark brown to black with yellow markings; legs (Fig. 27) mostly yellow with brown portions.
Description
Male genitalia. Pygofer (Fig. 28), in lateral view, strongly produced posteriorly, expanded apically. Subgenital plate (Fig. 29), in ventral view, subtriangular; base with lateral projection directed anteriorly (central emarginate area between pair of projections covered by valve); basal portion slightly expanded laterally, then tapering gradually towards apex; latter slightly curved dorsally; without “articulated” portion; in lateral view, plate extending almost as far posteriorly as pygofer apex. Connective (Fig. 30), in dorsal view, T-shaped; stalk narrow and very elongate, with dorsal median keel; arms poorly developed. Style (Fig. 30), in dorsal view, extremely elongate, extending posteriorly much farther than apex of connective, almost as far posteriorly as apex of subgenital plate; without preapical or median lobe; apex acute. Aedeagus (Fig. 31) symmetrical; shaft, in lateral view, curved dorsally on apical half, with large, dorsoapical rectangular lobe and pair of elongate, slightly asymmetrical apical processes that are not located at same plane. Anal tube (Fig. 32) without processes. Female unknown.
Etymology
Etymology. The name of the new species, distincta, refers to the conspicuous features of the aedeagus, i.e., lobe and processes (Fig. 31).
