DESCRIPTION
Body 8.39­9.85 mm in length, 4.60­5.45 mm in width, from castaneous to black, corium usually paler than pronotum and scutellum, at least costa and a part of exocorium brown or yellowish brown, sometimes also apices of pronotal umbones pale brown or yellowish brown.
Head dorsally alutaceous and impunctate except for setigerous punctures and sometimes a few very small punctures laterally; clypeus subapically without a pair of setigerous punctures, each paraclypeus submarginally with 2­5 setigerous punctures bearing long hair­like setae (Fig. 266); ocular index 2.10­2.70; interocellar index 7.0­12.0; length of antennal segments (in mm): 0.34­0.40: 0.45­0.60: 0.55­0.69: 0.76­0.88: 0.77­0.88.
Puncturation of pronotal disc well visible, punctures small, better visible behind head and calli, discal transverse impression behind calli absent or very shallow; lateral margins of pronotum with 6­10 submarginal setigerous punctures bearing long hair­like setae (Fig. 265). Anterior convexity of propleuron impunctate or almost impunctate, posterior convexity distinctly coarsely punctate close to propleural depression, the latter with a band of coarse punctures.
Scutellar disc densely punctate with almost evenly spaced punctures larger than those on pronotum, anterolateral angles of a disc impunctate.
Corium densely punctate; clavus with one complete and two incomplete rows of punctures; mesocorial disc densely and almost evenly punctate; exocorium more or less densely punctate; costa flattened, separated from exocorium only in its basal third, costal margin with 2­3 setigerous punctures (Fig. 265).
Femora from castaneous to almost black, tibiae yellow or yellowish brown, tibial spines dark brown or black; male hind femur with a row of teeth on its dorsal margin, among them three subapical, ventral margin with a row of well visible teeth, among them one large subbasal and three subapical (Fig. 267); male hind tibia with a row of very small denticles (Fig. 267); female hind femora with a row of setae on margins, female tibiae simple.
Abdominal sterna more or less polished, almost totally impunctate, bearing only a patch of few small punctures posterior to spiracles.
Male genitalia as in Figs 268­271.
