Key to the Himalayan species of subgenera Cesamya and Mycomyopsis 

1. Tergal part of male hypopygium with one, wide medial comb (and two inner combs) of spines ( Figs. 1View FIGURE 1 A, 1 C, 2 A, 3 A, 4 A).................................................................................... (subgenus Cesamya)... 2

- Tergal part of male hypopygium with two separate parallel combs (and two inner combs) of spines (e.g. Figs. 6View FIGURE 6 A, 8 A, 10 A, 12 A).................................................................... (subgenus Mycomyopsis  )... 5

2. Sternal submedian filament (stemming from basal-middle part of deeply bilobed sternal synsclerite) short, not extending beyond the apex of sternal synsclerite ( Fig. 1View FIGURE 1 B).................................................. M. cissa  sp. n.

- Sternal submedian filament long, extending far beyond the apex of sternal synclerite ( Figs. 2View FIGURE 2 B, 3 B, 4 B)................ 3

3. Base of tergal comb widely setose with only a narrow gap in the middle ( Fig. 3View FIGURE 3 A); gonostylus very long with a small membra- nous basal lobe much shorter than gonostylus ( Fig. 3View FIGURE 3 F)........................................... M. niltava  sp. n.

- Base of tergal comb only laterally setose with a wide bare median part ( Figs. 2View FIGURE 2 A, 4 A); gonostylus slightly longer than its mem- branous lobe ( Figs. 2View FIGURE 2 E, 4 E)............................................................................. 4

4. Tergal lateral appendage (one on each sides of outer tergal comb) with a flattened, curved seta in the middle of its inner margin, separated almost by its length from apical flattened setae ( Fig. 2View FIGURE 2 D).................................. M. goral  sp. n.

- Tergal lateral appendage without such an isolated flattened curved seta, all apical flattened setae close to each other ( Fig. 4View FIGURE 4 D)........................................................................................ M. sachak  sp. n.

5. No sternal submedian filament (e.g. Figs. 5View FIGURE 5 B, 8 B)........................................................... 6

- Sternal submedian filament well-developed (stemming from basal-middle part of deeply bilobed sternal synsclerite) (e.g. Figs. 9View FIGURE 9 B, 11 B, 12 B)........................................................................................ 9

6. Tergal lateral appendage widely and densely setose ( Figs. 5View FIGURE 5 A, 5 D)..................................... M. aix  sp. n.

- Tergal lateral appendage with two widely separate groups of setae, basal and apical, with narrow subapical part between them bare ( Figs. 8View FIGURE 8 C, 14 D, 15 C)............................................................................. 7

7. Middle part of gonostylus without a spur or a spine ( Fig. 15View FIGURE 15 D), outer tergal combs rudimentary ( Fig. 15View FIGURE 15 A)................................................................................................. M. unipectinata Edwards 

- Middle part of gonostylus with a short spur or a strong spine ( Figs. 8View FIGURE 8 D, 14 E), outer tergal combs well-developed ( Figs. 8View FIGURE 8 A, 14 A).................................................................................................................................................................................................... 8

8. Tergal lateral appendage long, slender, more than 5 x as long as wide, slightly curved, with a sparse group of a few basal setae ( Fig. 8View FIGURE 8 C)............................................................................... M. ducula  sp. n.

- Tergal lateral appendage very long, slender, about 7 x as long as wide, strongly curved, with a dense group of basal setae ( Fig. 14View FIGURE 14 D)................................................................................... M. sanar  n. sp.

9. Tergal lateral appendage widely setose, without wide bare areas ( Figs. 6View FIGURE 6 C, 7 C, 9 C, 10 C)........................... 10

- Tergal lateral appendage with two widely separate groups of setae, basal and apical, with long, slender subapical area bare ( Figs. 11View FIGURE 11 C, 12 D, 13 C)................................................................................ 13

10. Middle part of gonostylus without a spur or a strong spine ( Figs. 9View FIGURE 9 E, 10 D)....................................... 11

- Middle part of gonostylus with a short spur or a strong spine on the opposite site of the membranous lobe ( Figs. 6View FIGURE 6 D, 6 E, 7 D).................................................................................................... 12

11. Sternal submedian filament short, hardly reaching apex of sternal synsclerite ( Figs. 10View FIGURE 10 B, 10 D)............. M. jeti  sp. n.

- Sternal submedian filament long, curved, extending well beyond apex of sternal synsclerite ( Fig. 9View FIGURE 9 B)....... M irena  sp. n.

12. Apical setae of tergal lateral appendage about as long as flattened, curved subapical setae ( Fig. 6View FIGURE 6 C)....... M. alticola  sp. n.

- Apical setae of tergal lateral appendage much longer than flattened, curved subapical setae ( Figs. 7View FIGURE 7 C).... M. banteng  sp. n.

13. Basal part of gonostylus without a long spur ( Fig. 11View FIGURE 11 D)............................................. M. kaa  sp. n.
