: Antenna mostly dark gray; parafacial silvery white, concolorous with facial coloration; gena-to-eye ratio 0.27-0.30. Thorax: Wing with costal vein ratio 0.62-0.65; M vein ratio 0.57-0.60. Forefemur with comb-like row of distinct, short, stout setulae along apical half of posteroventral margin; hindtibia bearing a short seta, length subequal to width at same level. Abdomen: Tergites broadly dark gray medially, lacking wedge-shaped, gray to silvery gray areas laterally; tergite 5 of male mostly gray but with vague, slate gray medial stripe. Male terminalia (Figs 31-34): Combined structures generally moderately elongate, in posterior view height less than twice width (1.85
