Diagnosis: Medium sized, dark brown, legs yellow, mouthparts with palpi slender, mentum without pit or furrow, labial palpiger unisetose; head as wide as pronotum, lateral margins of pronotum deeply sinuate before hind angles, proepisternum invisible from above; elytra distinctly carinate, costae much narrower than depressions. Length: 10.0 mm; width: 4.0 mm. Habitus as in Fig. 3 . Whole body black, except yellowish on antennae, legs and palpi. Head longer than wide (HL/HW=1.18); labrum straight, sexsetose, clypeus quadrisetose, the additional two setae on inner portion; mandibular scrobe plurisetose, frons and vertex convex, frontal impressions punctured and setose, compound eyes rather small; palpi subcylindrical, pubescent; ligula dilated, plurisetose, adnated to paraglossae, labial palpomere 2 plurisetose, mentum without tooth and pit, with four setae, submentum with three pairs of setae; labial palpiger with one seta. Antennae extending to middle of elytra, antennomere 1 with several long setae, pubescent from antennomere 2; antennomere 3 much longer than the 1 and 2 combined. Pronotum quadrate ( Fig. 7 ), as long as wide, disc moderately convex, lateral margin long and gently sinuate before hind angle, hind angle nearly rectangular, not sharp. Disc wrinkled, sparsely punctured and pubescent.
