Diagnosis.

Anterior angles of pronotum protruding, pronotal disc with two or three irregular rows of fine punctures. Humeral groove of elytra shallow, punctures of elytra diminishing posteriorly, absent on apical 1/3. Femora of legs without tooth. Lateral metasternum with a long and arcuate strip of pubescence.

Redescription.

BL = 8.7-11.2 mm, BW = 3.0-4.5 mm. Body brownish red, head, antenna, legs and lateral metasternum with a blue metallic luster.

Head (Figs 15 View Figures 15–18 , 42A View Figures 37–46 ). Vertex flat, 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 1.5 × as long as wide, antennomere 11 slender.

Pronotum (Figs 15 View Figures 15–18 , 42B View Figures 37–46 ). Anterior angles slightly protruding, posterior angles not protruding; sides constricted in the middle; disc slightly raised; middle of disc with two or four irregular rows of fine punctures.

Elytra (Figs 15 View Figures 15–18 , 32B View Figures 32–36 ). Humeri protruding, humeral groove and basal impression distinct; elytra without completely punctate striae, punctures large in the base, diminishing posteriorly, absent on apical 1/4; intervals smooth; epipleura raised, with a sparse row of fine punctures.

Mesosternum pubescent. Lateral metasternum with a long and arcuate strip of pubescence, extending from anterior margin to lateroposterior corner, metepisternum densely pubescent (Fig. 42A View Figures 37–46 ).

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

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

Male genitalia (Fig. 52A-D View Figures 51–56 ). Ostium occupying 1/3 length of median lobe (Fig. 52A View Figures 51–56 ); apex crooked (Fig. 52B View Figures 51–56 ); 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, dorsal sclerite wedge-shaped in dorsal view, ventral sclerite short and tubular (= flagellum), median sclerite small (Fig. 52C, D View Figures 51–56 ).

Female reproductive organs (Fig. 59A-C View Figures 57–66 ). Tergites 8 and 9 and 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 curved.

Distribution

(Fig. 68 View Figure 68 ). China (Hunan, Yunnan, Guangxi, Guangdong, Hainan).

Host plant and habitat.

Host plant is unknown. One collecting place, Hongkan Reservoir in Baisha, Hainan, is located in a subtropical area. The habitat is a lake area surrounded by primeval forests with high temperature and humidity.

Remarks.

The species is similar to L. jianfenglingensis , but differs by the antennomeres 5-10 nearly 1.8 × as long as wide, and brownish red with a blue metallic luster (Fig. 32D View Figures 32–36 ); the disc of the pronotum with two or four irregular rows of fine punctures (Fig. 42A View Figures 37–46 ); and the dorsal sclerite of the male genitalia is strongly sclerotized (Fig. 52C, D View Figures 51–56 ). In L. jianfenglingensis , antennomeres 5-10 are almost as long as wide, and brownish red (Fig. 30D View Figures 27–31 ); the disc of the pronotum has two rows of fine punctures (Fig. 40B View Figures 37–46 ); and the ventral sclerite of male genitalia is weakly sclerotized (Fig. 54C, D View Figures 51–56 ).
