Diagnosis. Femora black; antennomeres 5–10 twice as long as wide; pronotal disc with sparse fine punctures; elytral punctures large at base, diminishing posteriorly, sparse or absent in apex; apex of mesoventral process slightly widened.

Redescription. BL 7.0–12.0 mm, BW 3.3–4.2 mm. Head, antennae, scutellum prosternum, mesoepisternum, mesoepimeron, metaepisternum, lateral sides of mesoventral, lateral sides of sternite, and legs black, remainders brownish red.

Head ( Figs 2 View Figures 1–2 , 11–12 View Figures 11–14 ). HL/HW 1.1–1.3; vertex with a deep groove in middle, punctate and setose laterally; occiput with a shallow furrow medially, densely punctate; frontal tubercle glabrous, slightly raised; frontoclypeal area triangular, disc with punctures and setae laterally; labrum transverse, with long setae; antennae filiform, nearly half as long as body length, antennomeres 1–4 nearly globular, 2 shortest, 5–10 each cylindrical, twice as long as wide; antennomeres 1–2 sparsely pubescent and punctate, 3–11 densely pubescent and punctate.

Pronotum ( Figs 2 View Figures 1–2 , 11 View Figures 11–14 , 19A View Figures 15–19 ). PW/HW 1.1–1.2, PL/PW 1.0–1.2; anterior angle protruding, posterior angle not protruding; side constricted in middle; disc with sparse fine punctures; anterior and posterior transverse impression absent, basal transverse groove weak. Scutellum triangular and densely pubescent.

Elytra ( Figs 2 View Figures 1–2 , 11 View Figures 11–14 ). EL/EW 2.1–2.2; sutural angle rounded; humeri protruding, humeral groove distinct, basal impression distinct; intervals with sparse fine punctures; strial punctures sparse, coarse at base, diminishing posteriorly, much sparser or absent at apex, scutellary striole composed of 2–5 punctures; epipleura with upper margin strongly raised, with a row of fine punctures laterally.

Mesoventrite pubescent; apical portion of mesoventral process slightly widened apically, convex, tuberculate, horizontally connected with metaventrite ( Fig. 19B View Figures 15–19 ); metaventral disc with a long arcing setose area, extending from posterior margin to anterior margin ( Fig. 19C View Figures 15–19 ); metepisternum densely pubescent.

Abdominal sternite with 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 setae on ventral surface.

Male genitalia ( Figs 23A–D View Figures 20–24 ). Median foramen occupying 1/5 length of median lobe aedeagus ( Fig. 23A View Figures 20–24 ); apex triangular ( Fig. 23B View Figures 20–24 ); tegmen Y shaped, slender, basal piece of tegmen triangular, lateral lobes strongly scleritized, combined with second connecting membrane; internal sac membranous, with dorsal, median, and ventral sclerites moderately scleritized, distal part of dorsal sclerite squarely shaped ( Figs 23C–D View Figures 20–24 ).

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

Distribution ( Fig. 30 View Figure 30 ). Russia (Siberia), Japan ( Heinze, 1943; Medvedev, 1958; Kimoto, 1961; Naito, 2012).

Host plant and habitat. Smilax china L. and S. riparia A. DC in Japan ( Naito, 2012). Habitat unknown.

Remarks. This species can be distinguished from L. neptis by the following features: pronotal disc nearly smooth, without rows of punctures; elytral punctures sparse in base. In L. neptis , the pronotal disc has two rows (rarely one row) of large punctures; elytral punctures are dense in base.
