Diagnosis. This species can be distinguished from other species by its black head and pronotum, and the reddish brown elytra without any spots. Redescription. Male. Length 8.4-10.6 mm, width 5.2-6.0 mm. Head, antennae, pronotum, scutellum and leg black, elytra reddish brown, ventral surface of thorax yellow with lateral area black, abdomen yellow. Vertex finely covered with punctures. Interocular space 1.6 x as wide as transverse diameter of eye. Interantennal space 1.5 x as wide as transverse diameter of antennal socket. Frontal tubercles transverse, each separated by a deep furrow; antennae slender, 0.65 x as long as body; antennomeres 1-3 shiny; antennomeres 4-11 covered with pubescence, antennomere 2 shortest, antennomere 3 approximately 1.5 x as long as second; antennomere 4 longest, approximately 1.8 x as long as antennomeres 2 and 3 combined; antennomeres 5-10 gradually shortened, shorter than antennomere 4; antennomere 11 slightly longer than antennomere 10, pointed.

Elytra: wider than pronotum, 0.75 x as long as body, 1.65 x as long as wide, epipleura wide at anterior 1/4, posteriorly gradually narrowing towards apex, dorsal surface convex slightly, covered with large punctures regularly, partially arranged in ten rows in each elytron, the interstices of punctures wider than diameter of punctures, approximately 2 x as wide as diameter of punctures, covered with small punctures. Metasternum 2 x as long as the mesosternum. Ventral surface of abdomen with five ventrites, ventrite 1 longest, ventrites 2-4 gradually shortened, apical ventrite slightly longer than ventrite 3, with two subtriangular incisions. Figure 24.
