Description.

Thorax: Mesonotum outer margin with regular row of forked thick setae.

Legs: Forefemur with transverse row of long and pointed thick setae across dorsal face; dorsal surface, outer and inner margin sparsely with short thick setae.

Abdomen: Tergite with median tubercles slightly developed on segments I to III, moderately developed on segment IV and IX-X, and well developed on segments V-VIII. No posterolateral projections on segments II and III, slightly developed on segments IV, and moderately developed on segments V-IX. Tergites IV-VI (Fig. 15D ) surface covered with short thin setae, thick setae with feathered apex and apically rounded feathered thick setae; posterior margin with long pointed thick setae, thick setae with feathered apex and apically rounded feathered thick setae. Tergites VII-X (Fig. 16D ) surface and posterior margin with short thin setae, thick setae with feathered apex and apically rounded feathered thick setae. Narrow slender teeth present on posterior margin median area of tergites I-VI (Fig. 15D ) and across entire posterior margin of tergites VII-X (Fig. 16D ).
