Body 6.93­7.38 mm in length, 4.16­4.55 mm in width, dark castaneous, posterior margin of pronotum narrowly yellowish brown, corium more yellow­brown in shade than scutellum, punctate with dark punctures.

Head dorsally slightly wrinkled and bearing numerous small, almost evenly spaced punctures; clypeus subapically with a pair of setigerous punctures bearing long hair­like setae, each paraclypeus submarginally with a row of 8­9 setigerous punctures bearing long hair­like setae (Fig. 273); ocular index 2.69­2.80; interocellar index 7.1­9.3; length of antennal segments (in mm): 0.35: 0.42­0.44: 0.38­.40: 0.53­0.54: 0.52­0.54.

Pronotal disc with scattered punctures or different size, calli impunctate; transverse discal impression behind calli shallow and almost indistinct, bearing medially interrupted row of several coarse punctures; lateral margins of pronotum with 16­21 submarginal setigerous punctures bearing long hair­like setae (Fig. 272). Anterior convexity of propleuron impunctate, except for a few small punctures anteriorly, posterior convexity with a few large punctures close to propleural depression, the latter with a row of well separated coarse punctures.

Scutellar disc with almost evenly spaced punctures larger than those on pronotum; basal fourth of scutellar disc impunctate.

Mesocorial disc evenly punctate with exception of its middle fifth; exocorium with very dense puncturation; costa broad and flat, separated from exocorium only in its basal two thirds, costal margin with 8­11 setigerous punctures bearing long hair­like setae (Fig. 272).

Femora castaneous, tibiae brown or yellowish brown; male hind femur with 2 subapical teeth on ventral margin, and a row of denticles on dorsal margin (Fig. 274); female hind femur with a row of small denticles on dorsal margin; male hind tibia with large subbasal lobe­like denticle and numerous smaller tubercles (Fig. 274); female hind tibia simple.

Abdominal sterna almost totally impunctate, except for rows of punctures parallel to segmental sutures, and longitudinal patches of punctures posterior to each spiracle.
