Description. Because the original description ( Péringuey 1896: 160–161) is quite detailed, we simply add the following: length 10.8–14.0 mm, width 3.0– 4.2 mm. Apical third of Ant 1 and basal two-thirds of Ant 3 black or dark brown; femora reddish brown with apical third or half black; tibiae nearly black. Head wider than pronotum ( Fig. 1 ), HW/PW 5 1.19 (1.11–1.30); Ant 1/Ant 3 5 3.40 (3.20–3.57); labrum with medial lobe slightly protruded anteriorly ( Fig. 25 ); genae long, slightly tumid; eyes large, about 1.8 times as long as genae. Pronotum widest slightly before middle, PL/PW 5 1.56 (1.45–1.62). Elytra with lateral margins nearly parallel; outer angles slightly dentate, not sharply pointed at apex ( Fig. 39 ), EW/PW 5 2.27 (2.09–2.56), EL/EW 5 1.89 (1.81–2.04). Protarsomere 3 strongly asymmetrical in male; tarsal claws with 5–6 pectinations on inner side, length of the longest pectination subequal to width of claw base ( Fig. 65 ). Aedeagus stout ( Fig. 108 ), with apical lamella narrow, thickened and rounded at apex ( Fig. 107 ).

Distribution. Angola, Cameroon, Congo, Kenya, Mozambique, South Africa, Senegal, Uganda, Zambia.

Remarks. We did not check the type. Our description is based on specimens determined by Basilewsky. Members of this species are readily distinguished from those of other members of the genus by their red pronota and long tarsal claw pectinations.
