Description. Because Sloane’s description (1907: 473) is detailed, we simply add the following: length 9.1–10.7 mm, width 2.6–3.5 mm. Femora brown, with apical ninth or tenth blackish brown; tibiae brown. Ant 1/Ant 3 5 3.37 (3.13–3.50); HW/ PW 5 1.16 (1.09–1.19); PL/PW 5 1.58 (1.53–1.65); EW/PW 5 2.41 (2.22–2.58); EL/EW 5 1.74 (1.62–1.81); labrum with medial lobe slightly protruded anteriorly; genae short, slightly tumid; eyes large, about 2.5 times as long as genae; elytra with lateral margins nearly parallel in both sexes; elytral outer angles strongly dentate, sharply pointed at apex ( Fig. 42 View Figs ); protarsomere 3 slightly asymmetrical in male; tarsal claws with 5 or 6 pectinations, longest pectination slightly longer than width of claw base ( Fig. 58 View Figs ). Aedeagus with apical lamella narrow, slightly digitiform ( Figs. 95–96 View Figs ).

Distribution. New Guinea.

Remarks. We have not examined the type. Members of this species can be recognized by their brown femora with very short dark apices. In most specimens, the elytra possess strongly dentate outer angles as described by Sloane (1907: 473), and in some specimens, the outer angles are sharpened into a short spine (e.g., from Jule Island). We found one specimen (in CAS) of this species with obtuse outer angles; but because it is similar to other specimens of this species in other characters, including shape of the aedeagus, this is probably just an abnormal specimen. This species is the only member of Dendrocellus distributed in New Guinea and appears to be endemic to this island.
