Pronotum yellowish brown with a black spot at front middle. Elytra black with dark blue luster. Legs dark brown. Antennae with fringe of long setae on venter of antennomeres 3–6. Elytral surface densely clothed with pale brown pubescence. All covered with brown hairs.

Body compressed and elongate. Head compressed and coarsely punctate, narrower than pronotum at widest point. Frons nearly flat, transverse; Eyes small with fine facets, divided into two widely separated lobes; lower lobes longer than genae. Interantennal region strongly impressed with antennal tubercles strongly elevated. Antenna of male extending beyond elytral apex by 3 antennomeres; third antennomere longer than scape and fourth; antennomere ratio: 6.3 - 1.0 - 10.0 - 8.6 - 8.6 - 5.9 - 5.9 - 4.0 - 3.6 - 3.1 - 2.7; scape stout and cylindrical, surface with coarse grain; third to seventh antennomere with spiny processes ventrally ( Fig. 3 View FIGURE 3. a b).
