DESCRIPTION
Body 4.75­5.70 mm in length, 2.73­3.19 mm in width, from dark castaneous to blackish brown, corium from castaneous to dark castaneous with punctures darker than the corial disc.
Head dorsally slightly wrinkled, at first glance looking impunctate, but bearing numerous hardly visible tiny punctures; clypeus subapically without a pair of setigerous punctures, each paraclypeus submarginally with 6­8 (usually 7) setigerous punctures bearing long hair­like setae (Fig. 218); ocular index 2.42­ 2.75; interocellar index 10.0­16.0; length of antennal segments (in mm): 0.20­ 0.28: 0.22­0.33: 0.26­0.35: 0.33­0.39: 0.35­0.43.
Pronotal disc distinctly punctate in its anterior and lateral parts and behind calli; transverse discal impression absent; lateral margins of pronotum with 7­9 submarginal setigerous punctures bearing long hair­like setae (Fig. 217). Anterior convexity of propleuron impunctate, posterior convexity impunctate except for a few punctures, propleural depression coarsely punctate.
Scutellar disc densely punctate with punctures larger than those on pronotum, anterolateral angles and apex impunctate.
Mesocorial disc entirely evenly punctate; exocorium densely punctate; costa narrow, almost entirely separated from exocorium, bearing 4­6 setigerous punctures (Fig. 217).
Margins of male and female hind femur without tubercles, subapical teeth absent (Fig. 219); male and female hind tibia simple, not specifically modified (Fig. 219).
Abdominal sterna almost totally impunctate, except for a row of punctures along each segmental suture, and a few coarse wrinkles and punctures posterior to spiracles and trichobothria.
Male genitalia as in Figs 220­223.
