1. Wing with distinct pigmentation ( Figs. 1 View FIGURES 1 – 2 , 15 View FIGURES 15 – 16 )............................................................... 2

- Wing without any distinct spots of pigmentation; some with discrete gradients of pigmentation ( Fig. 29)...................................................................................................... other Atrichopogon View in CoL

2. Wing with two transverse darker bands, one straddling the r-m to CuA2 and other covering the distal 1/3 of the wing ( Figs. 15 View FIGURES 15 – 16 )..................................................................................................... 3

- Wing with two distinct, darker spots, one over r-m and the other in cell r3 posterior to apex of R3 ( Fig. 1 View FIGURES 1 – 2 )................ 4

3. Distal 1/3 of the wing entirely in dark band; gonostylus thick for most of length with two pointed apical prongs ( Fig. 33 View FIGURE 30 – 35 )....................................................................................... maculipennis Clastrier

- Distal 1/3 of the wing with two ovoid pale spots, one subapically in r3 and other on apical portion of m1 and m2 ( Figs. 15 View FIGURES 15 – 16 ); gono- stylus progressively tapering and curved, bearing pointed apex ( Figs. 20 View FIGURES 17 – 23 , 24 View FIGURE 24 )............... cavus Felippe-Bauer View in CoL sp. nov.
