Diagnosis. Ant. I with one long finger-like process on the inner side ( Fig. 5b ), 0.61–1.00 times the segment; the antennal setae are short and pointed, and the longest setae of Ant. III 0.31–0.39 times the basal width; abdominal tergite VII with two paired short conical spinal tubercles ( Fig. 5e ), other tergites without tubercles; dorsal setae of abdominal tergites I–VI short and capitate, 0.13–0.49 times Ant. IIIBD, but the spinal setae of abdominal tergites VII–VIII long, thick and capitate, on swollen setal tubercles, 1.52–2.50 times Ant. IIIBD.
