Description. Length 11.6–12.8 mm, width 3.4–3.8 mm. Black with green and blue luster; apical third of Ant 1 black, basal two-thirds red or brown; femora brown with apical fifth or sixth black; tibiae brown; scutellum, and meso- and metasternum brown, prosternum and metepisterna also brown in some specimens. Head wider than pronotum, HW/PW 5 1.19 (1.15–1.23); Ant 1/Ant3 5 3.94 (3.69– 4.08); medial lobe of labrum slightly protruded anteriorly; genae very long, slightly tumid; eyes large, about 2.3 times as long as genae. Pronotum narrow, widest slightly before the middle; PL/PW 5 1.52 (1.47–1.55); lateral margins slightly widened from apical angles to widest point, gently narrowed behind, then slightly sinuate to basal angles; basal angles obtuse, pointed laterally; lateral furrow indistinct; basal foveae shallow; middle line fine. Elytra with lateral margins slightly widened to apical fourth, then narrowed to apex; outer angles acute, very slightly dentate; EL/EW 5 1.85 (1.70–1.94), EW/PW 5 2.33 (2.24–2.36); intervals flat, densely punctate. Protarsomere 3 strongly asymmetrical in male ( Fig. 51 ); tarsal claws with 5–6 long pectinations, length of the longest pectination subequal to width of claw base (similar to Fig. 65 ). Aedeagus stout, with apical lamella narrow, digitiform, thickened at apex ( Figs. 103–104 ).

Distribution. Angola, Cameroon, Congo, Gabon, Gambia, Senegal, Sierra Leone, Tanzania.

Remarks. We have not examined the types and have simply followed Basilewsky’s (1960) interpretation of the names and synonymies. All members of this species have brown meso- and metasterna and some also have the prosternum brown. In these and other features, they are very similar to another African species, D. australis ; but they differ from the latter in having blue pronota, longer ratio of Ant 1/Ant 3, and brown tibiae.
