Key to the species of the genus Cofana Melichar from India based on adult males and females

1. Pronotum with median longitudinal fuscous line extending onto scutellum ( Fig. 9 )..................................2

- Pronotum without median longitudinal fuscous line or, if line present, not extending onto scutellum ( Fig. 35 )................................................................................................................................................................5

2. Aedeagal shaft with two short acute processes anteapically ( Figs. 10, 11 ); female seventh sternite rounded ..................................................................................................................................... C. bidentata sp. nov.

- Aedeagal shaft without two short anteapical processes; female seventh sternite with bi- or trilobed caudal prolongation ( Figs. 26 , 34 )..........................................................................................................................3

3. Dark brown ( Fig. 6 ); aedeagal shaft triangular in lateral aspect ( Fig. 45 ) .................... C. spiculata sp. nov.

- Pale ochraceous ( Fig. 3 ); aedeagal shaft not triangular in lateral aspect ( Fig. 19 )......................................4

4. Aedeagal shaft broadest near base, strongly tapering distally, dorsal apodeme separated from shaft by less than maximum width of shaft in lateral aspect ( Fig. 28 ); female seventh sternite with caudal projection undulate ( Fig. 34 ) ............................................................................................................ C. nigrilinea (Stål)

- Aedeagal shaft gradually broadened to near apex and then narrowed ( Fig. 19 ), dorsal apodeme separated from shaft by more than maximum width of shaft in lateral aspect; female seventh sternite with caudal projection bilobed ( Fig. 26 ) ............................................................................................ C. lineata (Distant)

5. Anterior margin of head broadly rounded, with median apical spot ( Figs. 35 , 52 ), large species measuring> 7 mm ..........................................................................................................................................................6

- Anterior margin of head narrowly rounded, without median apical spot ( Fig. 60 ), small species measuring 5.9–7.0 mm .......................................................................................................... C. unimaculata (Signoret)

6. Forewing white, with appendix and surrounding areas of same texture as rest of wing; aedeagus in lateral aspect narrowly V-shaped ( Fig. 36 ); apex of style acutely pointed ( Fig. 41 ); female seventh sternite broadly convex with margin undulate ( Fig. 43 ) ............................................................ C. spectra (Distant)

- Forewing greenish ( Fig. 7 ); appendix and surrounding area membranous; aedeagus in lateral aspect broadly V-shaped ( Fig. 53 ); apex of style bluntly pointed ( Fig. 57 ); hind margin of female seventh sternite distinctly tridentate ( Fig. 59 ) ...................................................................................... C. subvirescens (Stål)
