Material examined. CHINA: 1♀ Ningxia, Liupanshan Forest Park (35°22'N 106°18'E), 3–4.VII.2009, leg. H-y. Chen ( SCAU); 1♀, Ningxia, Liupanshan Longtan Forest Farm (35°23'22"N 106°20'38"E), 6.VII.2008, J-m. Yao ( SCAU); 1♀, Yunnan, Xian Yenteng Village (24°7'27''N 104°7'46''E), 25.VII.2005, leg. K. Wu.

Diagnosis. Chrysellampus duplipunctatus Tsuneki, 1948 is similar to C. obtusidentibus Rosa, Wei & Xu , sp. nov. and C. heros (Semenov) for habitus and colouration. However, it can be separated by fine and shallow punctures on metasoma (large and deep in C. obtusidentibus ), and apex of T3 with median notch deep and with sharp teeth surrounded by thin rim ( Fig. 4 F) (blunted teeth without rim in C. obtusidentibus ); it can be separated from C. heros by shape of mesopleuron with large areolae and irregular punctures on lower margin (with small and round punctures in C. heros ).

Redescription. Female. Body length 7.1–7.3 mm. Fore wing length 4.5–4.7 mm. OOL = 2.2 MOD; POL = 2 MOD; MS = 0.5 MOD; relative length of P:F1:F2:F3 = 1:1.5:1:0.7.

Head. Head with large and deep punctures ( Fig. 4 A) on frons and lateral sides of scapal basin; punctures on vertex and occipital area smaller and subequal, with two impunctate areas close to ocelli; frons, occipital area and gena colliculate, with reticulate microsculpture on intervals between the punctures. Gena micropunctate and obliquely wrinkled. Scapal basin deep and transversely striated. Ocellar triangle isosceles; postocellar line indistinct. Occipital carina and genal carina sharp; the latter curved close to lower margin of eye, partially bisecting the MS.

Mesosoma. Pronotum impunctate antero-medially; with large and irregular punctures medially; with smaller and round subequal punctures laterally. Mesoscutum mostly with large and deep punctures, but impunctate anteriorly ( Figs 4 C, 4D). Notauli and parapsidal furrows complete. Mesoscutellum impunctate antero-medially, the rest punctate as mesoscutum. Pronotum, mesonotum, mesoscutellum and mesopleuron colliculate. Metanotum elongated and gibbous, with larger aerolate punctures. Propodeal angles large and straight, slightly divergent. Mesopleuron with omaulus sharply carinate and scrobal carina well developed ( Fig. 4 B).

Metasoma. T1, T2 and T3 with shallow punctures, denser to lateral margins and on T3. T3 without semitransparent rim. Apex of T3 with median notch bidentate, teeth with rim ( Fig. 4 F).

Colouration. Body metallic blue, with green spots on face, vertex, pronotum, mesoscutellum and mesopleuron. Scape, pedicel and F1 metallic green to blue, rest of flagellum black. Tegula dark brown, without metallic reflection. Legs metallic green; tarsi brown with metallic green reflections at least on the first tarsomere. Sternites metallic green.

Male. Unknown.

Remarks. The type of C. duplipunctatus Tsuneki, 1948 was not available for this study. It is strictly related to C. heros ( Semenov, 1932) . Description and drawings of the two species are matching. According to Tsuneki's description, he did not know any specimen of C. heros (Semenov) . In fact, the diagnosis of C. duplipunctatus was given in comparison with the European species C. sculpticollis (Abeille de Perrin, 1878). The main difference between the two species is shape of mesopleuron, which is without irregular foveate punctures in C. heros , but only with sharp and thick juncture between omaulus and scrobal carina. Moreover, based on Tsuneki's drawing, shape of metanotum in C. duplipunctatus is triangularly pointed downward, whereas in our Chinese specimens metanotum is regularly rounded.

Distribution. China (Liaoning, Jilin, Shanxi, Yunnan). Korea and Russian Far East ( Tsuneki 1953a, b; Kurzenko & Lelej 2007; Ha et al. 2008; Lelej & Kurzenko 2012).
