Figs 8–10
Diagnosis
This new species looks similar to A. mucida, but differs by: head with anterior margin angulated at about 90° (slightly acute angled in A. mucida); vertex 1.1 times as wide as long (1.1 times as long as wide in A. mucida); frons with one obviously short median carina (median carina almost absent in A. mucida).
Etymology
The specific name is a Latin feminine adjective ‘ sphaerica ’ to refer to the globular shape of the head.

Description
MEASUREMENTS. Male length (N = 1) (including tegmen): 14.2 mm, length of tegmen: 11.9 mm; female length (N = 2) (including tegmen): 16.1–16.5 mm, length of tegmen: 13.0– 13.5 mm.
COLORATION. Body and tegmina brown with dark brown marks; vertex, pronotum and mesonotum mottled, median carina of pronotum dark brown; frons light brown with apex mottled fuscous; gena yellowish brown, dorsal portion and anterior portion of eye marked with darker brown color; eyes black,
ocelli milk white; tegmina light brown, slightly transparent, marked with brown dots, apical portion and costal area dark brown (Fig. 8 A–B, D–F).
HEAD AND THORAX. Head anterior margin angulated, about 90°; vertex pentagonal; disc pressed; 1.1 times as wide as long, lateral margins highly raised; posterior margin raised, pressed in the middle; median groove full length of vertex, apex Y-forked (Fig. 8D). Frons disc flat, 1.1 times as long as wide, median longitudinal carina very short positioned at dorsal portion, lateral margins moderately raised (Fig. 8F). Frontoclypeal suture pressed, truncate; clypeus convex. Rostrum extending to metatrochanter (Fig. 8F). Antennae short. Pronotum with anterior margin truncate, slightly concave in the middle, disc pressed, lateral side thick and tended up, median carina weakly raised, ventral margin rolled upwards, postocular eminence evenly convex (Fig. 8 D–E). Mesonotum humped, anterior margin convex, disc flat, without carina (Fig. 8 D–E). Metatibia with six spines apically, metatarsal basal segment with two large spines and six small spines apically (Fig. 8C). Tegmina elongate, 11.6 mm in length, 5 mm in width, costal membrane 3.5 times as wide as costal cell at level of bulla; costal margin slightly undulate, apical margin convex, 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. 8B).
MALE GENITALIA. Pygofer ring-like, anterior margin concave, posterior margin convex, ventral margin truncate, dorsal margin concave (Figs 8H, 9A). Genital style ventral, dorsal and apical margins truncate, dorsal apex with a process apically, ventral apex concave (Figs 8H, 9A). Male anal tube elongated and arched (Fig. 8 G–H). Phallic complex arched (Figs 8I, 9 B–D). Periandrium tubular. Dorsal part of periandrium distinctly shorter than ventral part in lateral view, median lobe narrow and acute. Each side of lateral part of periandrium with a recurved process, not forked. Ventral part of periandrium distinctly slender and tapering in ventral view (Fig. 9 E–G). Aedeagus bipartite; fourth of dorsal portion apparently elevated; each side of apex without process; apex of lateral portion with a sharply short prominence (Fig. 9 H–J).
FEMALE GENITALIA. Female anal segment small, oval in dorsal view, apex slightly concave (Fig. 10B). Gonapophysis VIII slender, trangular, apex with 7 teeth, dorsal margin evenly concave, ventral margin convex (Fig. 9K); gonapophysis IX short and slender, apex acute (Fig. 9 L–M); gonoplac with arrays of strong marginal teeth (Figs 9N, 10A).
Distribution
Zhejiang and Guangxi Province, China.
