Diagnosis
This new species is similar to A. punctulata sp. nov., but differs from the latter by the following characters: tegmina with a large black patch (without a large patch in A. punctulata sp. nov.); costal membrane 3.2 times as wide as costal cell (4 times as wide as costal cell in A. punctulata sp. nov.); periandrium with a pair of processes, apex of processes forked (periandrium with paired processes, apex of processes not forked in A. punctulata sp. nov.).
Etymology
The specific name is a feminine adjective ‘ ocularia ’ to emphasize a big eye shaped spot on the tegmina.

Description
MEASUREMENTS. Male length (N = 1) (including tegmen): 13.5 mm, length of tegmen: 12.1 mm.
COLORATION. Body and tegmina yellowish brown with black markings; vertex yellowish brown marked with dark patches; frons light brown with dorsal apex and longitudinal carina black; gena yellowish brown, dorsal portion and anterior portion of eye marked with darker brown color; eyes brown, ocelli milk white; dorsal apex of antennal segment II black marked; pronotum and mesonotum yellowish brown, lateral carinae black, disc mottled; tegmina yellowish brown, veins brown or black, a large black patch positioned after fork of vein MP, 1.3 mm in diameter (Fig. 1 A–B, D–F).
HEAD AND THORAX. Head anterior margin convex; vertex pentagonal; disc pressed; longer than wide; lateral margins parallel, highly raised at posterior portion; posterior margin raised, median groove full length of vertex, apex T-forked (Fig. 1 D–F). Frons disc flat, 1.3 times as long as wide, median longitudinal carina almost half length of frons, lateral margins moderately raised (Fig. 1F). Frontoclypeal suture pressed, truncate; clypeus convex. Rostrum extending beyond metatrochanter (Fig. 1F). Antennae short. Pronotum with anterior margin truncate, lateral side thick and tended up, median carina obscure, ventral margin rolled upwards, postocular eminence evenly convex (Fig. 1 D–E). Mesonotum slightly humped, anterior margin convex, disc flat, without carina but lines. Metatibia with six spines apically, metatarsal basal segment with nine spines apically (Fig. 1C). Tegmina elongate, 13 mm in length, 5 mm in width; costal membrane 3.2 times as wide as costal cell at the 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 and costal membrane with reticulated crossveins and pustulate; one subapical line present (Fig. 1B).
MALE GENITALIA. Pygofer ring-like, anterior margin concave, posterior margin convex, dorsal and ventral margins more or less truncate (Figs 1G, 2A). Genital style ventral and apical margins convex, dorsal margin concave, with a process (Figs 1G, 2A). Male anal tube elongated, evenly bent down (Figs 1 G–H, 2A). Phallic complex arched. Periandrium tubular. Dorsal part of periandrium slightly shorter than ventral part in lateral view, median lobe narrow and acute. Each side of lateral part of periandrium with forked process, recurved. Ventral part of periandrium distinctly tapering apicad in ventral view (Figs 1I, 2 B–D). Aedeagus bipartite; each side of apex without process; apex of lateral portion with even prominence.
Distribution
Hainan Province, China.
