Body oval, black, slightly shining. Head broad, punctures of frons sparser on middle than on sides, punctures with setae; anterior and lateral margins of clypeus straight; genae narrower than eyes. Antennae broad, reaching to the base of pronotum; 3rd segment 3.5 times as long as broad, terminal segment approximately globose; relative length ratio of 2nd to 11th segments as follows: 9.0: 26.0: 16.0: 18.0: 18.0: 18.0: 13.0: 13.0: 10.0: 5.0. Pronotum 1.6 times as broad as long; anterior margin straight, faintly bordered; lateral margins arcuate in apical 2/3, and straight in basal 1/3, broadest at apical 1/3, fine border invisible in dorsal view; base broadly bordered; anterior angles acute and protruding, posterior angles obtuse; disc feebly convex, middle line short, umbilicate granules with hair, and the granules sparser on middle than on sides. Elytra broadly oval, 1.3 times as long as broad, 3.0 times as long as pronotum; base W shaped, humeri round; lateral margin arcuate; humeral rows of granules obvious; humeri finely and sparsely granuliferous; granules of marginal rows thick on basal 1/2, becoming smaller and denser backwards; disc flatly convex; granules 2.5 times as the space among them as diameter of themselves between marginal and 3rd lateral rows; 3rd lateral rows slightly obvious, granules inside the rows slightly thick and dense, and always attrite; apex finely and densely granuliferous. Pseudopleuron finely and sparsely granuliferous. Propleura with dense hairs, round granules sparse, and gradually became lesser inwards; prosternal process mightily curved beyond procoxae, and triangular and thickly bordered apically; mesosternum broad, and evenly arched, never gibbous. Abdomen sparsely and finely granulilerous, and with dense hairs. Paramera of aedeagus 1.3 times as long as basal piece, and middle flat in dorsal view; lateral margins straight, apex finely digitiform; lateral margins of basal piece arcuate, apex round. Ovipositor short and broad, valvula oval. Protibiae gradually broadened apically. Meso- and metatibiae slightly broadened apically. The ratio of relative length of metatarsi 1st to 4th segments as follows: 28.0: 11.0: 10.0: 27.0. Measurements. Body length: 17.0 21.0 mm; width: 9.0 11.0 mm. Distribution.
