Description. Andrewes (1931) provided a detailed description and illustration. We simply add the following: length 9.4–10.4 mm, width 2.9–3.3 mm. Apical (not basal as stated in original description) four fifths of Ant 1 black; femora brown, with apical sixth or seventh black; Ant 1/Ant 3 5 3.45 (3.33–3.56); HW/PW 5 1.17 (1.12–1.21); PL/PW 5 1.53 (1.48–1.57); EW/PW 5 2.36 (2.18–2.42); EL/EW 5 1.72 (1.64–1.81); labrum with medial lobe slightly protruded anteriorly; genae short, slightly tumid; eyes moderately large, 2.5 times as long as genae; elytral punctation as in Fig. 45 View Figs ; protarsomere 3 symmetrical in male ( Fig. 53 View Figs ); tarsal claws with 5–6 pectinations, length of the longest pectination subequal to the width of claw base (similar to Fig. 63 View Figs ); last sternum as in Fig. 48 View Figs or 50. Aedeagus with apical lamella thin, linguiform ( Figs. 83–84 View Figs ).

Distribution. Indonesia (Sumatra), Malaysia (N. Kalimantan).

Remarks. We have not examined the type (in BMNH). Members of this species are readily recognized by their elytral intervals sparsely punctate ( Fig. 45 View Figs ), femora with apical sixth black, and tibiae completely black.
