Length.

17.0 mm; width: 6.5 mm. Habitus as in Fig. 10.

Description.

Dark brown to black, body rather slender and depressed, smooth and glabrous, microsculptural engraved meshes isodiametric on head, pronotum and elytra. Head longer than wide, HL/HW = 1.16, eyes rather small; labrum straight at frontal margin, sex-setose, clypeus bisetose; each of mentum and submentum each with a pair of setae. Pronotum strongly transverse, PW/PL = 1.60, widest a little before middle, lateral expanded margins well-marked, almost flat; elytra elongate-ovate, EL/EW = 1.73, convex, base well-bordered, parallel-sided, striae deep, intervals strongly convex, apex faintly sinuate, inner angle nearly rectangular, distinctly denticulate at tip (Fig. 20); the 3rd interval with two well-marked setiferous pores, median one wanted. Legs moderately long, the 4th hind tarsomere shorter than the 3rd, lobes of 4th tarsal emarginations half long as the tarsomere; tarsal claws weakly pectinate. Prosternal process well-bordered at apex; abdominal ventrite VII not emarginate at apical margin in male. Male genitalia (Figs 36-37) stout and short, apical lamella short, as wide as long at apex, tip almost truncated.

Remarks.

Differs from other members of this species group by its labrum straight at front, and 3rd elytral interval with only two setiferous pores.
