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. Femora of legs without tooth. Lateral metasternum with a long strip of pubescence. Redescription. BL = 6.3-7.2 mm, BW = 2.5-3.5 mm. Body brownish red. Head (Figs 17 , 43A ). Vertex strongly convex, with a shallow 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 nearly 1.1 x as long as wide, antennomere 11 slender. Pronotum (Figs 17 , 43B ). Anterior angles protruding, posterior angles not protruding; sides slightly constricted in the middle; disc flat; middle of disc with four or five rows of fine punctures. Scutellum triangular and pubescent. Elytra (Figs 17 , 33B ). Humeri protruding, humeral groove and basal impression distinct; elytra without completely punctate striae, punctures sparse and large in the base, diminishing posteriorly, absent on apical 1/3; intervals smooth; epipleura raised, with a row of fine punctures. Mesosternum pubescent . Lateral metasternum with a long and arcuate strip of pubescence, metepisternum densely pubescent (Fig. 43C ). Abdominal sternite (Fig. 33A ). Lateral transverse impressions small and indistinct on sternites 1-4, other areas of sternites 1-4 densely pubescent. Leg (Fig. 33C ). Femora with dense pubescence on the dorsal surface, with sparse pubescence on the ventral surface, without tooth. Male genitalia (Fig. 48A-D ). Ostium occupying 1/4 length of median lobe (Fig. 48A ); apex hooked (Fig. 48B ); tegmen Y-shaped, basal piece of tegmen triangular and broad, lateral lobes slightly sclerotized and combined with second connecting membrane; internal sac membranous, with distinct dorsal, median and ventral sclerites, posterior part of dorsal sclerite in dorsal view slightly widen, ventral sclerite short and flaky, median sclerite slightly sclerotized (Fig. 48C, D ). Female reproductive organs (Fig. 63A-C ). 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. 67 ). China (Sichuan, Yunnan); Laos ( Warchalowski 2011 ); Thailand, new record from China. Host plant and habitat (Fig. 71A, B ). The host plant of this species is Smilax bracteata Presl according to our observation in Xishuangbanna. It shares the same habitat with L. latissima in Baihua Shan of Xishuangbanna, Yunnan. Remarks. This species is most similar to L. semipunctata , but differed by the strongly convex vertex (Fig. 43A ); the disc of pronotum has three or four rows of fine punctures (Fig. 43B ); the posterior part of the dorsal sclerite is slightly widened in dorsal view, quadrate at the apex (Fig. 48C ). In L. semipunctata , the vertex is slightly convex (Fig. 44A ); the disc of the pronotum has two rows of fine punctures (Fig. 44B ); and the posterior part of the dorsal sclerite is parallel in dorsal view, rounded at apex (Fig. 50C ). This species has obvious sexual dimorphism: the middle of the abdominal sternites have a dense pubescence in the male, but the middle of these abdo-minal sternites are smooth in the female.
