Figs 3–5

Diagnosis

This new species looks similar to A. ungulata sp. nov., but differs from the latter by: pronotum anterior margin concave in the middle (truncate in A. ungulata sp. nov.); process of lateral lobe of periandrium not forked (forked in A. ungulata sp. nov.).

Etymology

The specific name is derived from the Latin word ‘ patefactus ’ which refers to the flat tegmina.

COLORATION. Body and tegmina green with black markings; vertex green marked with dark patches; frons light green with dorsal apex and longitudinal carina fuscous; gena yellowish green, dorsal portion and anterior portion of eye marked with darker brown color; eyes black, ocelli milk white; pronotum dull green, median carina fuscous; mesonotum dull green, heavily mottled, each posterior margin with triangular black spot; tegmina dull green, cross vein of costal area and veins of apical cell brown or black (Fig. 3 A–B, D–F).

HEAD AND THORAX. Head anterior margin pointed, about 80°; vertex pentagonal; disc pressed; longer than wide; lateral margins slightly raised; posterior margin raised, pressed in middle; median groove full length of vertex, apex Y-forked (Fig. 3 D–F). Frons disc flat, 1.4 times as wide as wide, median longitudinal carina almost half length of frons, lateral margins moderately raised (Fig. 3F). Frontoclypeal suture pressed, evenly convex; clypeus convex. Rostrum extending beyond metatrochanter (Fig. 3F). Antennae short. Pronotum with anterior margin concave in middle, disc pressed, lateral side thick and tended up, median carina obscure, ventral margin rolled upwards, postocular eminence evenly convex (Fig. 3 D–E). Mesonotum humped, anterior margin convex, disc flat, without carina but lines (Fig. 3 D– E). Metatibia with six spines apically, metatarsal basal segment with two large spines and nine small spines apically (Fig. 3C). Tegmina elongate, 11.5 mm in length, 4.5 mm in width, costal membrane 3.8 times as wide as costal cell at level of bulla; costal margin undulate, apical margin convex and sinuate, sutural margin truncate, apical and sutural angles convex; vein ScP+RA elevated ridgelike above plane of vein Pc+CA and crossing pustulate bulla, CuA forked, clavus with few crossveins; one subapical line present (Fig. 3B).

MALE GENITALIA. Pygofer ring-like, anterior margin strongly concave, posterior margin convex, ventral margin evenly convex, dorsal margin concaved (Fig. 3H). Genital style ventral and apical margins convex, dorsal margin concave, with a process apically (Fig. 3H). Male anal tube elongated, apex bent down (Fig. 3 G–H). Phallic complex slightly arched (Fig. 3 I–K). Periandrium tubular. Dorsal part of periandrium distinctly shorter than ventral part in lateral view, median lobe acute. Each side of lateral part of periandrium with recurved process, not forked. Ventral part of periandrium distinctly tapering apicad in ventral view (Fig. 4 A–C). Aedeagus bipartite; each side of apex without process; apex of lateral portion with obviously raised prominence (Fig. 4 D–F).

FEMALE GENITALIA. Female anal segment small, oval in dorsal view, apex slightly concave (Fig. 5B). Gonapophysis VIII slender, trangular, apex with 8 teeth, dorsal margin evenly concave, ventral margin convex (Fig. 4G); gonapophysis IX short and triangular, apex acute (Fig. 4H, I); gonoplac with arrays of strong marginal teeth (Figs 4J, 5A).
