Diagnosis

Atracis punctulata sp. nov. is similar to A. fimbria , but differs from the latter by: body and tegmina greenish and yellow (brownish in A. fimbria ); disc of vertex pressed (flat in A. fimbria ); preocesses of periandrium extending cephaloventrad and parallel (ventrad and crossed in A. fimbria ).

Etymology

The specific name is derived from the Latin word ‘ punctum ’, which refers to the mottled color of the tegmina.

Holotype

CHINA • ♂; Guangdong Province, Mt Nanling ; 8 May 2009; NWAFU.

Description

MEASUREMENTS. Male length (N = 1) (including tegmen): 15.1 mm, length of tegmen: 13.1 mm.

COLORATION. Body and tegmina greenish and yellow with black markings; vertex green heavily marked with dark color; frons light greenish yellow and mottled fuscous; gena yellowish green, dorsal portion and anterior portion of eye marked with darker brown color; eyes black, ocelli milk white; pronotum dull green and yellow, heavily fuscous; mesonotum dark brown, marked with black spots, heavily mottled; tegmina light greenish with black markings ( Fig. 6 A–B, D–F).

HEAD AND THORAX. Head anterior margin convex, vertex pentagonal; disc pressed; as long as wide, lateral margins highly raised at posterior portion; posterior raised, pressed in the middle; median groove full length of vertex, apex Y-forked ( Fig. 6 D–E). Frons disc flat, 1.3 times longer than wide, median longitudinal carina no more than half length of frons, lateral carinae positioned at dorsal portion no longer than median longitudinal carina; lateral margins sinuate, highly raised ( Fig. 6F ). Frontoclypeal suture pressed, truncate; clypeus convex. Rostrum extending beyond metatrochanter ( Fig. 6F ). Antennae short. Pronotum with anterior margin truncate, slightly concave in middle, disc pressed, lateral side thick and tended up, median carina weakly raised, ventral margin rolled upwards, postocular eminence evenly convex ( Fig. 6 D–E). Mesonotum humped, anterior margin convex, disc flat, tricarinate ( Fig. 6 D–E). Metatibia with six spines apically, metatarsal basal segment with two large spines and eight small spines apically ( Fig. 6C ). Tegmina elongate, 13.8 mm in length, 6 mm in width, costal membrane 4 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. 6B ).

MALE GENITALIA. Pygofer ring-like, anterior margin strongly concave, posterior margin convex and slightly sinuate, ventral margin truncate, dorsal margin concave ( Fig. 6H ). Genital style ventral and apical margins convex, dorsal margin concave, with a process apically ( Fig. 6H ). Male anal tube elongated, apex bent down ( Fig. 6 G–H). Phallic complex slightly arched. Periandrium tubular. Dorsal part of periandrium distinctly shorter than ventral part in lateral view, median lobe short and acute; each side of apex with three or four small teeth. Each side of lateral part of periandrium with recurved process, not forked, extending to half length of periandrium. Ventral part of periandrium distinctly slender and tapering apicad in ventral view ( Figs 6 I–K, 7A–C). Aedeagus bipartite; each side of apex without process; apex of lateral portion with an evenly pointed prominence ( Fig. 7 D–F).

Distribution

Guangdong Province, China.
