: Antenna mostly dark gray; parafacial silvery white, concolorous with facial coloration; gena-to-eye ratio 0.15-0.17. Thorax: Wing with costal vein ratio 0.77-0.81; M vein ratio 0.47-0.49. Forecoxa whitish gray to gray; hindtibia with prominent ventroapical, shallowly curved, spur-like seta. Abdomen: Tergites broadly brown medially, becoming lighter gray laterally but unevenly, almost shallowly wedge-like, tergite 5 of male gray with a thin, medial brown stripe (Fig. 12).
