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.
