 Type locality. Jiangxi, China.   
 Diagnosis. Elytra with sharp outer angles (Fig. 41), intervals densely punctate; femora with apical third black, basal-two thirds brown; tibiae and tarsi yellow, protarsomere 3 asymmetrical in male; tarsal claws with 5–6 long pectinations, length of the longest pectination equal to width of claw base (Fig. 60).   
 Description. Length 10.6–11.0 mm, width 3.1–3.4 mm. Black, head and pronotum with blue luster mixed with slight green luster; elytra with green luster mixed with slight coppery luster; apical third of Ant 1 dark brown, basal twothirds brown, Ant 2 and Ant 3 brown, Ant 4–11 yellow; apical third of femora black, basal two thirds brown; tibiae and tarsi yellow. Head wider than pronotum, HW/PW 5 1.22 (1.18–1.27); vertex convex; Ant 1/Ant 3 5 3.53 (3.47– 3.64); labrum (Fig. 27) coarsely punctate, with medial lobe slightly protruded anteriorly; genae long, moderately tumid; eyes large, 2.5 times as long as genae. Pronotum densely punctate, narrow, PL/PW 5 1.53 (1.47–1.60); lateral margins gradually widened from apical angles to middle, sinuate before basal angles; basal angles protruded laterally, nearly rectangular; basal foveae very deep; middle line shallow. Elytra short, EL/EW 5 1.75 (1.69–1.79), EW/PW 5 2.19 (2.11–2.33); lateral margins widened posteriad to apical third, then narrowed to apex; outer angles strongly dentate, pointed (Fig. 41); intervals convex, densely punctate, interspace between two adjacent punctures narrower than diameter of punctures. Protarsomere 3 slightly asymmetrical in male; tarsal claw with 6–7 pectinations, the longest pectination subequal to the width of claw base (Fig. 60). Aedeagus with apical lamella short, round at apex (Figs. 101–102).   
 Variation. The pronotum in the holotype is shorter (PL / PW 5 1.47), and lateral margins are more rounded than in the paratypes (PL / PW 5 1.52–1.60).   
 Distribution. Presently known from three provinces of China: Jiangxi, Fujian, and Guangdong.   
 Etymology. This new species is named for China, the country of its type locality.   
 Remarks. Members of this new species are similar to those of D. unidentatus (Macleay). However, the lateral margins of the pronota are more rounded before the middle (Fig. 20), the femora have a longer black portion, the tibiae are yellow, and the genae are more rounded than in D. unidentatus members. They are similar also to D. schultzei (Heller) members in shape of the pronotum and elytral outer angles, but differ from the latter in having green and coppery elytra and their tibiae and bases of femora all pale yellow (all black in D. schultzei).
