Description. Length 9.5–10.4 mm, width 2.4–2.9 mm. Black with green and blue luster; apical third of Ant 1 black, basal two-thirds brown; femora yellow or brown with apical sixth or eighth black; tibiae yellow. Head wider than pronotum, HW/PW 5 1.27 (1.18–1.33); Ant 1/Ant3 5 3.41 (3.21–3.62); labrum with medial lobe moderately protruded anteriorly ( Fig. 28 ); genae moderately tumid, eyes large, about 2.3 times as long as genae. Pronotum narrow, PL/PW 5 1.66 (1.57–1.74); lateral margins nearly parallel in apical two thirds. Elytra with lateral margins nearly parallel in both sexes; EL/EW 5 2.04 (1.85–2.13), EW/PW 5 2.18 (2.00–2.29); outer angles slightly dentate; intervals flat, densely punctate. Protarsomere 3 slightly asymmetrical in male; tarsal claws with 3–5 short pectinations, length of the longest pectination shorter than half width of claw base ( Fig. 69 ). Aedeagus with apical lamella thin, wide, linguiform ( Figs. 77–78 ).

Distribution. Bhutan, China, India, Indonesia (Java, Sumatra, Sulawesi), Laos, Malaysia, Myanmar, Pakistan, Thailand.

Remarks. The syntype of D. coelestinus (Klug) we examined is teneral, with bluish purple luster on pronotum and elytra. D. parallelus Chaudoir was described from Sumatra. When we compared the type of D. parallelus with that of D. coelestinus , we were unable to find any significant difference.

Chaudoir (1861: 545) treated D. coelestinus (Klug) as a synonym of D. unidentatus (Macleay) . Andrewes (1927: 100) disagreed with this treatment and pointed out that D. coelestinus (Klug) was probably a pale variety of D. geniculatus (Klug) . However, adults of D. coelestinus have very much shorter tarsal claw pectinations (Andrewes also noticed this character, 1927: 100) and males have a triangular lamella of the aedeagus, and, therefore, this species is distinct from D. geniculatus (Klug) .
