Key to species of Nothybus from China

[Simplified from Lonsdale & Marshall (2016)]

1 Distal quarter of wing infuscated, except for 2 discreet circular spots anteriorly in radial cells, and sometimes one ill-defined pale patch in cell m 1 ( Figs 7 View FIGURES 3–11 , 25 View FIGURES 21–28 , 34 View FIGURES 30–37 )...................................................................... 2

- Distal quarter of wing with dark brown apical and subapical bands; pale area between bands encompassing three clear spots ( Figs 44 View FIGURES 40–48 , 63 View FIGURES 59–67 , 83 View FIGURES 79–86 )...................................................................................... 4

2 Velvety anterolateral patches on frons confluent, black area thus continuous across lower frons ( Fig. 4 View FIGURES 3–11 ); fore basitarsomere almost entirely white, with basal and distal dark areas no longer than diameter of tarsomere ( Fig. 8 View FIGURES 3–11 )............. N. absens

- Velvety anterolateral patches on frons separate, black area of lower frons interrupted medially ( Figs 22 View FIGURES 21–28 , 31 View FIGURES 30–37 ); fore basitarsomere white except for dark apex and base, basal dark area several times longer than diameter of tarsomere ( Figs 26 View FIGURES 21–28 , 35 View FIGURES 30–37 )......... 3

3 Abdominal tergites mostly yellowish orange with dark markings posteromedially and along lateral margin ( Figs 20 View FIGURE 20 , 27, 28 View FIGURES 21–28 )............................................................................................ N. acrobates

- Abdominal tergites almost entirely dark brown ( Figs 29 View FIGURE 29 , 36, 37 View FIGURES 30–37 )...................................... N. biguttatus

4 Subapical clear spots of wing arranged in a straight transverse line; vein CuA1 with subapical spot usually distinct ( Figs 44 View FIGURES 40–48 , 63 View FIGURES 59–67 )................................................................................................. 5

- Subapical clear spots of wing not arranged in a straight line and middle spot in cell r 4+5 displaced apically, subapical spot on vein CuA 1 faded or absent ( Fig. 83 View FIGURES 79–86 )................................................................ N. sumatranus

5 Abdominal tergite 3 dark brown ( Fig. 46 View FIGURES 40–48 ); tergite 4 mostly dark brown, with large orange patches on each side ( Figs 46–48 View FIGURES 40–48 ); anterior margin of surstylus almost straight ( Fig. 76 View FIGURES 75–77 )................................................... N. kempi

- Abdominal tergite 3 laterally reddish brown to orange ( Fig. 58 View FIGURES 57–58 ); tergite 4 almost entirely reddish brown to orange, medial strip and anterior and posterior margins narrowly darkened ( Fig. 65 View FIGURES 59–67 ); anterior margin of surstylus strongly convex ( Fig. 77 View FIGURES 75–77 )........................................................................................... N. kuznetsovorum
