Description. Length 10.2–11.2 mm, width 2.7–3.0 mm. Black with green luster; Ant 1 with apical fourth blackish brown, basal three fourths yellow; femora yellow, with apical sixth black; tibiae yellow. Head slightly wider than pronotum, HW/PW 5 1.19 (1.12–1.24); labrum with medial lobe strongly protruded anteriorly ( Fig. 30 View Figs ); Ant 1/Ant 3 5 2.62 (2.50–2.67); genae slightly tumid, eyes large, about 2.3 times as long as genae. Pronotum widest at the middle, slightly narrowed anteriorly, PL/PW 5 1.58 (1.45–1.67). Elytra long, lateral margins nearly parallel in both sexes; outer angles slightly dentate, EW/PW 5 2.21 (2.03–2.31), EL/EW 5 1.99 (1.93–2.05). Protarsomere 3 slightly asymmetrical in male; tarsal claws with 3 or 4 pectinations, length of the longest pectination less than half width of claw base ( Fig. 67 View Figs ). Aedeagus with apical lamella thin, triangular ( Figs. 73–74 View Figs ).

Distribution. China, India, Indonesia (Java, Sumatra, Kalimantan), Japan, Laos, Pakistan, Thailand.

Remarks. We have not examined the type. Members of this species are readily recognized by the strongly protruded medial lobe of the labrum, which is unique in the genus. Dendrocellus confusus is widely distributed in southeastern Asia from Japan and China to Java. Hansen (1967: 406) stated that adults of this species were similar to those of D. geniculatus (Klug) in having short tarsal claw pectinations. However, he wrongly characterized D. geniculatus (Klug) (see remarks under D. geniculatus ). Actually, adults of this species are similar to those of D. coelestinus (Klug) in having short claw pectinations, but different from the latter in having a longer medial lobe of the labrum and smaller ratio of Ant 1/Ant 3.
