6 Fastigium verticis as wide or wider than first segment of antenna. Tegmina narrow and long, with both margins sub-parallel. Greatest width of female ovipositor much less than 3 mm ( Fig. 29 ). ( India, China) .. .......................................................................................................... Indogneta Ingrisch & Shishodia, 2000

- Tegmina rather narrow, less than 1.5 times wider than the length of pronotum; tegminal stridulatory area with apical half of arcuate posterior margin straight. Male subgenital plate rather elongate, split from base and strongly upcurved; widest at base, then gradually sharpened apicad without pseudo-styli (Figs. 4749).

10 Male ninth abdominal tergum arcuately produced posteriorly, more or less covering abdominal apex. Male tenth abdominal tergum fused with epiproct forming a large and highly modified supra-anal plate of varying shape; Male subgenital plate divided almost from base; lobes diverging and strongly bowed dorsad or anterior-dorsad. (Oriental Region) .................................................................... Letana Walker, 1869

- Male ninth and tenth abdominal terga normal. Male epiproct short and emarginated. Male subgenital plate mostly divided from middle, with lobes diverging and slightly bowed dorsad. ( India, Srilanka, China)...... ................................................................................................................................ Himertula Uvarov, 1940
