Diagnosis.

Femora bicolored, black with brownish red middle; pronotum disc with fine punctures; elytral punctures strong, not diminishing posteriorly, intervals convex at apical 1/4; lateral side of metasternite with a wide strip of pubescence; abdominal transverse impressions present on lateral area of sternites 2-5, glabrous, other area of sternite pubescent.

Redescription.

BL = 6.2-9.0 mm, BW = 3.0-4.5 mm. The front part of the head, antennae, ventral surface black; occiput, pronotum, scutellum and elytra brownish red, femora bicolored, brownish red with apex black.

Head (Fig. 6 View Figures 6–11 ). HL/HW = 1.1-1.2; vertex with a shallow groove in the middle, punctate and setose laterally; frontoclypeal area triangular, disc with dense punctures and setae; labrum transverse, with long setae on both apical angles; antennomeres 5-10 slightly longer than their widths (Fig. 33 View Figures 30–41 ).

Pronotum (Fig. 15B View Figures 12–17 ). PW / HW = 0.9-1.1, PL / PW = 1.0-1.1; anterior angle slightly protruding; posterior angle not protruding; sides distinctly constricted in the middle; middle of disc with fine punctures; anterior and posterior transverse impression indistinct, basal transverse groove shallow.

Elytra (Fig. 15D View Figures 12–17 ). EL/EW = 1.4-1.6; sutural angle rounded; humeri protruding, humeral groove shallow, basal transverse impression indistinct; scutellary striole composed of 4-7 punctures; strial punctures large, not diminishing posteriorly, intervals convex at apical 1/4; epipleura raised, with a row of fine punctures.

Mesosternite pubescent; lateral side of metasternite with wide strip of pubescence, extending from anterior to posterior margin, lateral 1/4 near metepisternum glabrous (Fig. 15B View Figures 12–17 ); metepisternum densely pubescent.

Lateral transverse impressions present on abdominal sternites 2-5, other area of sternite densely pubescent (Fig. 15C View Figures 12–17 ).

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

Male genitalia (Fig. 21A-D View Figures 18–23 ). Median foramen occupying 1/5 length of median lobe (Fig. 21A View Figures 18–23 ); apex rounded (Fig. 21B View Figures 18–23 ); basal piece of the tegmen triangular, relatively broad, lateral lobes weakly sclerotized; posterior part of dorsal sclerite in dorsal view more or less parallel-sided, slightly narrowed at apex (Fig. 21C, D View Figures 18–23 ).

Female reproductive organs (Fig. 27A-C View Figures 24–29 ). Spiculum gastrale long, Y-shaped, distal part slightly widened, apical margin rounded; ovipositor with dense setae, distal part of the ovipositor cylindrical, short, with a small protuberance; spermatheca simply convoluted.

Distribution.

Beijing, Shandong, Shaanxi, Henan, Jiangsu, Hubei, Hunan, Zhejiang, Jiangxi, Fujian, Guangxi, Yunnan, Sichuan, Guizhou; Korea ( Cho and An 2020).

Host plant and habitat.

(Figs 47-50 View Figures 47–50 ) This species feeds on Dioscorea polystachya according to our field observation in Beijing (Fig. 49 View Figures 47–50 ).

This species lives on elevations from 131 to 3200 m. One collecting locality of L. sinica in Beijing (Fig. 50 View Figures 47–50 ) is situated at the north temperate zone. The climate here is a temperate monsoon climate, with hot and rainy summers, and cold and dry winters with an average temperature below 0 °C. Affected by the climate, temperate deciduous broad-leaved forests grow here. The host plant Dioscorea polystachya shares habitat with other plants such as Metasequoia glyptostroboides ( Cupressaceae ), Juniperus chinensis ( Cupressaceae ), Pinus tabuliformis ( Pinaceae ), Syringa oblata ( Oleaceae ), Morus alba ( Moraceae ), Vitex negundo var. heterophylla ( Lamiaceae ), Inula japonica ( Asteraceae ), Polygonum aviculare ( Polygonaceae ), Potentilla chinensis ( Rosaceae ) and Oxalis corniculate ( Oxalidaceae ).

Remarks.

Lilioceris rugata sparsipunctata Medvedev, 1958 was described from Zhejiang and Lilioceris chinensis ( Jacoby 1888) was described from Jiangxi. Gressitt and Kimoto (1961: 58) synonymized them with L. sinica . We compared the types (Figs 4 View Figures 4, 5 , 5 View Figures 4, 5 ) and agree with their treatment.

Lilioceris jakobi ( White 1981) was originally described as Lilioceris minima by Jakob (1961) from Zhejiang and Fujian ( White 1981). This species is similar to L. chinensis according to original literature ( Jakob 1961), but it has a smooth pronotum, so should not belong to the Lilioceris sinica group. Unfortunately, the status of this species is unclear because we could not locate the type depository.
