Diagnosis. Femora bicolored, black with middle brownish red in ventral; antennomeres 5–10 twice as long as wide; pronotal disc with a longitudinal row of large punctures; elytral punctures sparse in basal half, absent on apical 1/2 or 1/3; apex of mesoventral process strongly widened.

Redescription. BL 9.0– 10.2 mm, BW 4.2–4.5 mm. Head, antennae, scutellum, prosternum, mesoepisternum, mesoepimeron, metaepisternum, and tibiae black, femora brownish red in middle, remainder black, pronotum, elytra, mesoventrite, metaventrite and abdominal sternites brownish red.

Head ( Figs 3–4 View Figures 3–6 ). HL/HW 1.1–1.3; vertex with a groove in middle, punctate and setose laterally; occiput with a furrow medially, sparsely punctate; gena punctate and setose; frontal tubercle glabrous, slightly raised; frontoclypeal area triangular, disc with punctures and setae; labrum transverse, with long setae; antennae filiform, nearly half as long as body, antennomeres 1–4 nearly globular, 2 shortest, 5–10 each cylindrical, twice as long as wide; antennomeres 1 and 2 sparsely pubescent and punctate, 3–11 densely pubescent and punctate.

Pronotum ( Figs 3 View Figures 3–6 , 16A View Figures 15–19 ). PW/HW 1.2–1.3, PL/PW 1.1–1.3; anterior angle laterally protruding; posterior angle not protruding; sides constricted in middle; anterior margin with a fine line of punctures, middle of disc with a row of large punctures; anterior and posterior transverse impression absent, basal transverse groove weak. Scutellum triangular and pubescent.

Elytra ( Fig. 3 View Figures 3–6 ). EL/EW 2.1–2.3; sutural angle rounded; humeri protruding, humeral groove distinct, basal impression indistinct; intervals smooth; strial punctures sparse and large in base, but absent on apical 1/2 or 1/3; scutellary striole with 2–5 punctures; epipleura with upper margin slightly raised, with a row of fine punctures laterally.

Mesoventrite pubescent; apical portion of mesoventral process strongly widened, convex, tuberculate, horizontally connected with metaventrite ( Fig. 16B View Figures 15–19 ); lateroposterior corner of metaventrite with a short oblique stripe of setae ( Fig. 16C View Figures 15–19 ); metepisternum densely pubescent.

Abdominal sternites with sparse setae and punctures, transverse impressions distinct on sternites 2–5, with dense punctures and pubescence.

Legs slender; tibiae with dense punctures, pubescence, and two spurs; femora with dense pubescence on dorsal surface, with sparse pubescence on ventral surface.

Male genitalia ( Figs 20A–D View Figures 20–24 ). Median foramen occupying 1/4 length of median lobe ( Fig. 20A View Figures 20–24 ); apex of median lobe triangular ( Fig. 20B View Figures 20–24 ); tegmen Y shaped, slender, basal piece of tegmen triangular, broad, lateral lobes strongly scleritized, combined with second connecting membrane; internal sac membranous, with dorsal, median, and ventral sclerites strongly scleritized, distal part of dorsal sclerites slightly widened ( Figs 20C–D View Figures 20–24 ).

Female reproductive organs ( Figs 27A–C View Figures 25–29 ). Tergites 8 and 9, sternites 8 and 9 sclerotized, posterior areas of tergite 8 and sternite 8 with long setae, without apodemes; spiculum gastrale Y shaped, long, slightly widened in distal part, apical margin rounded; vaginal palpi with dense setae, long and cylindrical; spermatheca simply folded.

Distribution ( Fig. 30 View Figure 30 ). China (Shaanxi, Henan, Shanghai, Anhui, Zhejiang, Jiangxi, Fujian, Guangxi, Guangdong, Guizhou, Sichuan).

Host plant and habitat. The host plant is Smilacacea based a label of the specimen from Tianmushan (see above, material examined). Dr. Kaiqin Li recorded it feeding on Smilax sp. in Guangxi Province ( Fig. 31 View Figures 31 ). Adults present from April to July.

This species is confined to southern and central China, in montane areas at the elevation from 600 to 1715 m. One collecting location recorded by Dr Caixia Yuan in Tianmu Shan (Fig. 32) is situated at the subtropical area. The vegetation is subtropical evergreen and deciduous mixed forest. The climate is characterized by four distinct seasons, abundant rainfall and mild temperature. The forests are composed of tall trees, woody vines and epiphytes. The host plant Smilax sp. shares its habitat with other plants such as Pinaceae , Lauraceae , Theaceae , Magnoliaceae , Poaceae and Asteraceae .

Remarks. This species looks very similar to L. neptis ( Weise, 1922) , but is different by its outer area of metaventral disc with a shorter oblique stripe of setae, elytral strial punctures sparse and large in the basal impression, and absent on apical 1/2 or 1/3. In L. neptis , the metaventral disc has a longer arc stripe of setose, extending from the posterior margin to the anterior margin; elytral striae has regular punctures, at most absent at apex. In addition, the genitalia of the species are obviously different by having a smaller aedeagus and weaker sclerosis on the dorsal sclerite.

Heinze (1943: 104) reported two species: L. cantonensis and L. melli , and deposited their type specimens in NHMB and MNHU, respectively. Gressitt & Kimoto (1961: 55) synonymized them with L. neptis but did not provide any reason, and later works followed this treatment ( Schmitt, 2010; Warchałowski, 2011; Bezděk & Schmitt, 2017). Therefore, L. cantonensis is different from L. neptis by having elytral punctures absent on apical 1/2 or 1/3 ( Fig. 3 View Figures 3–6 ), so it should be treated as a distinct species. Meanwhile, the type of L. melli ( Fig. 5 View Figures 3–6 ) is also checked, and without significant difference with L. neptis , so the status of L. melli is followed with Gressitt & Kimoto’s treatment.
