DESCRIPTION

Body 6.63­7.57 mm in length, 3.66­4.21 mm in width, from castaneous to almost black, corium paler than pronotum and scutellum.

Head dorsally polished, at first glance looking impunctate, bearing very small irregularly scattered punctures; clypeus subapically without a pair of setigerous punctures, each paraclypeus submarginally with a single preocular setigerous puncture (Fig. 225); ocular index 2.23­2.51; interocellar index 6.0­ 7.7; length of antennal segments (in mm): 0.29­0.33: 0.33­0.43: 0.39­0.47: 0.50­ 0.65: 0.57­0.75.

Pronotal disc almost impunctate, bearing a few small irregularly scattered punctures; transverse discal impression behind calli absent; lateral margins of pronotum with 5­6 submarginal setigerous punctures bearing long hair­like setae (Fig. 224). Anterior convexity of propleuron more or less punctate anteriorly and laterally, posterior convexity with a few irregularly scattered punctures, propleural depression with a broad band of coarse punctures.

Puncturation of scutellar disc irregular, well visible in its median part.

Mesocorial disc almost evenly punctate with punctures as large as those on scutellum; exocorium densely punctate; costa narrow, convex and raised, almost entirely separated from exocorium, bearing a single setigerous puncture (Fig. 224).

Femora castaneous or dark castaneous, tibiae basally brown or yellowish brown getting darker towards tarsi; male hind femur with a few very small, almost indistinct denticles bearing short setae on dorsal margin (Fig. 226); male hind tibia with a few very small, sometimes almost indistinct denticles on its inner margin (Fig. 226); female hind femur and tibia without denticles on inner margins.

Abdominal sterna polished, slightly wrinkled, coarsely punctate only close to lateral margins of segments, around trichobothria and posterior to spiracles.
