Artimpaza brevilineata Tian & Chen , sp. nov. ( Figs 1–9 )

Description. Female: Head and prothorax pitchy black; antennal segments 1 to 5 pitchy black and remainder dull pitchy brown to slightly reddish; scutellum black; each elytron blackish green with a fairly broad median, semitransparent, longitudinal strip; posterior thorax and abdomen pitchy black; legs black, femora clavate. Body moderately clothed with long erect pale hairs; underside of basal six antennal segments with somewhat shorter darker setae ( Figs 4–8 ); scutellum and parts of thoracic pleura and half of metaepisternum with dense silvery pubescence ( Fig. 9 ).

Head as wide as prothorax, moderately punctured and with one longitudinal groove extending onto frons ( Fig. 2 ); gena nearly 1/2 as deep as lower eye-lobe. Antenna almost reaching to elytral apex; scape swollen preapically, moderately punctured ( Fig. 3 ); segment 3 longer than scape + segment 2, and twice as long as segment 4; segment 4 as long as scape but shorter than segment 5; segment 11 as long as segment 10. Prothorax more than 1.5 times as long as wide, subcylindrical apically, somewhat constricted near base, feebly widened at side, widest just behind middle; disc with a slight swelling on each side near base, and with anterior portion largely smooth with sparse punctures. Each elytron about 7 times longer than wide, gradually narrowed behind humerus, disc fairly even, with very sparse punctures; elytra flattened above, narrowed and somewhat dehiscent posteriorly, each elytron spined at apex. Ventral surface with only a few punctures. Femora pedunculate, strongly clavate; hind femora extended to elytral apex; hind tarsal segment 1 distinctly longer than 2+3.

Measurements. Holotype, female. Body length 11.1 mm; width 2.0 mm; paratype, female. Body length 12 mm; width 2.4 mm.

Specimens examined. Holotype, female, China: Yunnan Province, Jinghong, 25 May 2010, coll. LI-CHAO TIAN. Paratype: 1 female, China: Yunnan Province, Lincang, 1 June 1980, coll. FEN LIU. The holotype and the paratype are housed in the collection of the College of Plant Protection, Southwest University, Chongqing, China (SWU).

Remarks. Ordinarily, we would hesitate to describe a new species based on one sex. However, given the robust morphological difference within the same sex there can be no doubt that A. brevilineata is a distinct species. The new species is similar to A. curtelineata Pic, 1922 , but differs mainly by each elytron being blackish green with a distinct median semitransparent strip.

Etymology. The species is named for the semitransparent strip on each elytron.
