Bronze with metallic purple; hind wings absent; pronotum lacking setigerous punctures on both anterior and posterior corners; elytra slightly shagreened and with regular double striae, interstrial punctures small and very sparse; inner edge of epipleuron with bristles along apical third of its length; hind tarsomere 3 complete and entirely pubescent beneath; hypomeron without punctures and without notopleural suture; pygidium with shallow median groove; basal part of median lobe much narrower than apical part, flagellum slender and long.

Description (based on holotype). Colour. Bronze with metallic purple; antennomeres 1–4 and claws reddish brown.

Body. Length: 5.92 mm; width: 3.20 mm; elongate, moderately large ( Fig. 8 ), convex in lateral view; hind wings absent.

Head.Anterofrontal ridge sinuous; clypeus trapezoidal, with sparse pubescence and without punctures, base not raised; middle part of labrum incised; frons smooth, with sparse, small punctures; coronal suture present, frontal suture present but not very distinct; vertex with sparse and small punctures; eyes elliptic, interocular distance 1.28 mm, dorso-ventral eye length 0.64 mm; outer surface of mandible with sparse pubescence and moderately large and dense punctures; maxillary palpomere 3 shorter than palpomere 4, apex of the latter truncate. Antennae extending to base of elytra, with narrow segments; lengths of antennomeres 1–11 (in mm): 0.32: 0.16: 0.24: 0.16: 0.16: 0.16: 0.24: 0.32: 0.32: 0.32: 0.48 ( Fig. 9 ).

Cilia of anterior margin present, anterior margin bordered, posterior margin bordered; lateral margin slightly dilated anterior to middle, distinctly visible from above, lacking setigerous punctures on both anterior and posterior corners; punctures on disc sparse and small, same as those on head, punctures laterally to disc slightly larger.

Scutellum. Subtriangular, with sparse punctures.

Elytra. Length along suture: 4.32 mm; combined width: 3.52 mm; humeral calli present; elytra with regular double striae, sutural striole present, punctures as strong as those on sides of pronotum, interstrial punctures small and very sparse, elytra slightly shagreened. Epipleuron horizontal, smooth, outer border sharp, inner edge with bristles along apical third of its length.

Venter. Hypomeron without punctures and without notopleural suture; cilia present on anterior margin of prosternum; middle part of intercoxal prosternal process more than half as wide as apex; prosternum without punctures, truncate posteriorly, not emarginate; anterior coxal cavities open posteriorly; mesoventrite shorter than prosternum between coxae; intercoxal process of metaventrite bordered anteriorly, metaventrite shorter than prosternum; mesepisternum without punctures, mesepimeron and metepisternum with small and sparse punctures; abdominal ventrites with sparse and small punctures; ventrite 1 without carina, last ventrite of male without emargination; pygidium with arcuate apex and shallow groove medially.

Median lobe of aedeagus ( Figs. 13–14 ). Basal part of median lobe much narrower than apical part; flagellum slender and long.

Females on average slightly larger and broader than males. Spermatheca simple, ductus common, without chitinous bulb ( Fig. 29 ).

Variability. All specimens more or less similar in shape and lustre.

Measurements (paratypes): Body length: 5.76–6.56 mm; body width: 3.04–3.36 mm; pronotum length: 2.56–2.88 mm; pronotum width: 1.12–1.28 mm; length of elytra along suture: 4.32–4.96 mm; combined width of elytra: 3.52–3.84 mm; dorso-ventral eye length: 0.62– 0.32 mm; interocular distance: 0.96–1.28 mm; average lengths of antennomeres 1–11 (in mm): 0.32–0.36: 0.16: 0.24–0.28: 0.16–0.18: 0.16–0.18: 0.16–0.18: 0.24: 0.32: 0.32: 0.32: 0.48 ( Fig. 10 ).

Remarks. Chrysolina jelineki sp. nov. is similar to C. dohertyi Maulik, 1926 . Both species have double striated elytra, sparse interstrial punctures, and similar aedeagi. However, C. jelineki differs in having antennomeres 6–11 not strongly thickened, the scutellum with sparse punctures, and the apex of aedeagus broader in dorsal view ( Figs. 13–16 ). BECHYNĚ (1950) regarded C. dohertyi as a member of the subgenus Anopachys Motschulsky, 1860 , but DAC- CORDI (1980) included it in the subgenus Hypericia Bedel, 1899 because of the double row of punctures on the elytra. However, BIEŃKOWSKI (2001) considered that this species has some character states which differ from Hypericia , such as the pronotal lateral depression separated from the disc by a wide impression covered with large punctures basally, conspicuous shape of the aedeagus (flat with a narrow and long apical projection and very narrow, whip-shaped flagellum), and concluded that this combination of characters makes it difficult to include C. dohertyi in Hypericia . We agree with his opinion here and we leave C. jelineki sp. nov. in an uncertain position similar to C. dohertyi for the time being.

Etymology. Named with respect and affection for Josef Jelínek, past curator in the Department of Entomology, National Museum, Prague.

Distribution. China: Yunnan.
