DIAGNOSIS
Dimension. Body length (pronotum–elytra): 8.1–12.0 mm; width 4.7–6.0 mm (body size depends on size of host seed).
Color. Integument black, sometimes reddish at apex of antennae, vestiture gray and brown, dense, conspicuous, especially on ventral segments (Figs. 15 and 16). Pronotum with 3 gray stripes medially and laterally. Elytra with gray vertical striae, sometimes widened at middle. Hind femur with 2 glabrous spots on dorsum.
Head elongate; frontal carina present. Eyes rather flat, emarginate to 2/5 length of eye. Antennal articles: 5–11 pectinate. Pronotum subtrapezoidal, greatest width at base (W/L = 1.27), sides almost straight (Fig. 15). Metasternal process strongly convex in lateral view. Elytra about 1.23 times longer than wide. Last 2 tergites (including pygidium) exposed behind elytra. Last sternite emarginate up to base in male, not emarginate in female. Hind femur strongly incrassate; dorsal side of hind femur granulate and with 1 large, sharp spine with 5–7 gradually smaller, blunt denticles following (Fig. 17).
Male genitalia. Median lobe elongate (Fig. 20), apex ogival (Fig. 22), bent ventrad; middle of internal sac lined with minute denticles (Fig. 21); lateral lobes fused into gutter-like structure; apex of lateral lobes distinctly concave in middle (Fig. 18); apex of gutter-like structure covered with many setae (Fig. 19).
Female genitalia. Ovipositor 2 times longer than wide, weakly sclerotized (Fig. 23). Stylus with 2 short setae (Fig. 24). First pair of baculum elongate almost 2 times longer than 2nd pair (Fig. 23). Apodeme of spiculum gastrale extending to apex of genitalia. Plate of spiculum gastrale as long as apodeme. Apex of ovipositor with 2 protuberances (Fig. 24). Spermatheca C-shaped (Fig. 8).
DISTRIBUTION
