Thorax. Mesonotum densely punctured (Fig. 10B); scutellum strongly elevated with a broad and deep middle furrow, sparsely punctured; mesepisternum above carina densely but shallowly punctured mixed with microsculptures, oblique carina on mesopleuron sharp, mesepimeron largely polished, shiny (Fig. 10F); cenchri elliptical, distance between inner margin of cenchri 2.3 × the longest axis of a cenchrus (Fig. 10B). Abdomen. Abdominal tergum 1 minutely punctured mixed with microsculptures, without lateral smooth patch; lateral carina low but recognizable, anterior corner blunt, posterior corner roundish; posterior margin with broad and incision, bottom not round with obtuse middle process (Fig. 10G, H); middle process of sternum 7 narrow and triangular, basal breadth about 1/6 breadth of sternite 7; lance long and slender, subapical annuli clearly broadened, total length of annuli 5.3 × height of 13th annulus, first annulus 1.8 × as high as broad (Fig. 10J); lancet with 52 annuli and 51 serrulae (Fig. 10J), middle serrulae weakly narrowed toward truncate apex, each side with 4-5 large subbasal teeth, distance between middle serrulae 2.2 × basal breadth of serrulae (Fig. 10K).
