Colour. Black with bronze lustre; antennomeres 1 and 2 reddish brown; eyes yellowish brown; apex of labrum, apex of clypeus, middle part of mandible, maxilla and galea reddish brown; onychium and claws yellowish brown. Body. Length: 6.40 mm; width: 3.40 mm. Elongate-ovoid, large; convex in lateral view; hind wings absent (Fig. 1). Head. Subprognathous, flat in lateral view; anterofrontal ridge sinuous. Clypeus trapezoid, with sparse pubescence and moderate punctures, base not raised; labrum incised anteromedially; frons smooth with sparse and moderate punctures; coronal suture present, frontal suture absent; vertex with sparse, moderate punctures; eyes oblong, dorso-ventral eye length (measured between dorsal and ventral side of eye) 0.36 mm, interocular distance 1.12 mm; mandible strong, with two denticles, outer surface with sparse and moderate punctures and dense pubescence; maxillary palpomere 3 shorter than palpomere 4, apex of the latter truncate. Antennae extending to base of elytra, with narrow segments; preapical segments as long as broad, not flattened; lengths of antennomeres 1–11 (in mm): 0.32: 0.24: 0.32: 0.24: 0.24: 0.24: 0.32: 0.32: 0.32: 0.32: 0.52 (Fig. 2). Prothorax. Length: 1.64 mm; width: 3.28 mm; trapezoidal, cilia of anterior margin present; anterior and posterior margin bordered; lateral margin narrow, distinctly visible from above and lacking setigerous punctures on both anterior and posterior corners; disc smooth, not strongly dilated anterior to middle; punctures on central portion moderate and dense, larger than those of head; disc without antebasal transverse impression and with shallow lateral longitudinal depression and dense punctures in depression near lateral side; punctures lateral to disc large and dense. Scutellum. Subtriangular, with sparse and small punctures. Elytra. Length along suture: 5.12 mm; combined width: 4.48 mm. Humeral callus absent; elytra with confused punctures; punctures smaller than those of side of pronotum; epipleuron horizontal, with outer border sharp, inner edge with sparse bristles along apical third of its length. Legs. Femora slender, with sparse and moderate punctures and sparse pubescence; tibiae slender, with sparse and moderate punctures and sparse pubescence; tibiae with coarse punctures dorsally and dense pubescence apically; apices of all tibiae not expanded externally; fore tarsomere 1 enlarged; hind tarsomere 3 complete and entirely pubescent beneath, with shallow emargination; relative lengths of hind tarsomeres: 5&gt;1&gt;3&gt;2, tarsomere 5 not ventrally toothed (Fig. 4); tarsal claws simple. Venter. Hypomera wrinkled and without punctures; cilia present on anterior margin of prosternum; middle part of intercoxal prosternal process more than half as wide as apex; prosternum with dense and large punctures, shagreened, truncate posteriorly, and not emarginate; anterior coxal cavities open posteriorly; mesoventrite shorter than prosternum between coxae; intercoxal process of metaventrite bordered and not truncate anteriorly; metaventrite shorter than prosternum, with moderate and dense punctures; mesepisternum, mesepimeron and metepisternum with moderate and sparse punctures; abdominal ventrites with sparse and moderate punctures; ventrite 1 without carina; ventrites not extending to sides; last abdominal ventrite of male without emargination; pygidium with arcuate apex and long deep longitudinal depression medially. Median lobe of aedeagus (Figs. 5–6). Basal part of median lobe broader than apical part, curved in lateral view. Female (based on paratypes) distinctly larger and broader than male. Fore tarsomere 1 not enlarged, hind tarsomere 3 with pubescence beneath restricted to ventro-lateral sides. Spermatheca simple, ductus without chitinous bulb (Fig. 7). <b>Variability.</b> All males of the type series are very similar in size, shape and lustre, some specimens are metallic dark green on dorsum. The aedeagus of most specimens are identical, only the individuals from Shiren Shan, Henan, have the apex slightly narrower and more elongate. Measurements (paratypes): Body length: 6.24–8.64 mm; body width: 3.20–4.96 mm; pronotum length: 1.52–2.24 mm; pronotum width: 2.88–3.92 mm; length of elytra along suture: 5.28–7.04 mm; combined width of elytra: 4.08–6.08 mm; dorso-ventral eye length: 0.24–0.32 mm; interocular distance 1.12–1.68 mm; lengths of antennomeres 1–11 (in mm): 0.36–0.48: 0.24: 0.32–0.48: 0.24–0.32: 0.24–0.32: 0.24–0.32: 0.32: 0.32: 0.32: 0.32–0.40: 0.48 (Fig. 3). <b>Remarks.</b> <i>Chrysolina josefi</i> sp. nov. is somewhat similar to <i>Chrysolina</i> (<i>Chrysocrosita</i>) <i>sulcicollis</i> (Fairmaire, 1887) for the punctures of pronotum and elytra, but differs in the morphology of the aedeagus. <b>Etymology.</b> Named in honour of our friend and colleague Josef Jelínek, past curator in the Department of Entomology, National Museum, Prague. <b>Host plants.</b> <i>Artemisia</i> Linnaeus (Asteraceae). <b>Distribution.</b> China: Henan, Shanxi and Shaanxi.
