Diagnosis.

Anterior angles of pronotum protruding, pronotal disc with four or five irregular rows of fine punctures. Humeral groove of elytra distinct, punctures of elytra sparse and diminishing posteriorly, absent on apical 1/3. Meso- and meta-femora without tooth. Lateral metasternum with a long strip of pubescence.

Redescription.

BL = 7.0-8.5 mm, BW = 3.0-3.8 mm. Body brownish red.

Head (Figs 19 View Figures 19–22 , 44A View Figures 37–46 ). Vertex flatted, with a deep groove in the middle, sparse punctate and pubescent laterally; frontoclypeal area triangular, lateral disc with sparse punctures and pubescent; labrum transverse, with sparse pubescent; antennae nearly 1/2 of body length, antennomeres 1-4 nearly globular, antennomere 2 shortest, antennomeres 5-10 almost as long as wide, antennomere 11 slender.

Pronotum (Figs 19 View Figures 19–22 , 44B View Figures 37–46 ). Anterior angles protruding, posterior angles not protruding; sides slightly constricted in the middle; disc flatted; middle of disc with 3-5 rows of fine punctures. Scutellum triangular and pubescent.

Elytra (Figs 19 View Figures 19–22 , 34B View Figures 32–36 ). Humeri protruding, humeral groove and basal impression distinct; punctures dense and large in the base, diminishing posteriorly, absent on apical 1/4; intervals without punctures; epipleura raised, with a sparse row of fine punctures.

Mesosternum pubescent. Lateral metasternum with a long and arcuate strip of pubescence, metepisternum densely pubescent. Metepisternum densely pubescent (Fig. 44C View Figures 37–46 ).

Abdominal sternite (Fig. 34A View Figures 32–36 ). Lateral transverse impressions big and distinct on sternites 1-4, other areas of sternites 1-4 densely pubescent.

Leg (Fig. 34C View Figures 32–36 ). Femora with dense pubescence on the dorsal surface, with sparse pubescence on the ventral surface, without tooth.

Female reproductive organs (Fig. 64A-C View Figures 57–66 ). Tergites 8 and 9, sternites 8 and 9 sclerotized, posterior areas of tergite 8, sternite 8, and apodemes with pubescence, spiculum gastrale Y-shaped and long; ovipositor with dense pubescence, distal part of ovipositor cylindrical, long and with a protuberance; spermatheca simple and hooked.

Distribution

(Fig. 68 View Figure 68 ). China (Sichuan, Yunnan, Guangxi, Hainan); Vietnam.

Host plant and habitat

(Fig. 72A, B View Figure 72 ). The host plant of this species is Smilax perfoliata Lour. according to our observation in Yunnan. It lives at altitudes of 500-2000 m. One locality of this species in Menghai (Yunnan, Xishuangbanna) is situated at the subtropics. The habitat is tea plantation, adjacent to primeval forests with high temperature and humidity, and plenty of sunlight.

Remarks.

This species is special in this group due to its strong cupreous metallic luster, the pronotal disc having 3-5 rows of fine punctures, and lateral metasternum with a long and arcuate strip of pubescence.
