Key to genera of subtribe Hecalina from India (males) (modified from He, et al., 2019)

1. Vertex and pronotum with red or orange inverted V- shaped marks (He, et al., 2019: Figs. 52, 53 ), aedeagus with well-developed dorsal apodeme and paired forked terminal processes, without ventral groove (He, et al., 2019: Figs. 63, 64)........................................................................................... Linnavuoriella Evans

- Vertex and pronotum without red or orange inverted V- shaped marks, with longitudinal subparallel brown, orange or yellow bands or without distinct markings ( Figs.1–5 )............................................................... 2

2. Vertex and pronotum without orange or yellow longitudinal bands ( Figs. 1–4, 6–9 ), aedeagus with one or two terminal processes, with ventral ridge, dorsal apodeme well developed ( Figs. 20 , 31 , 38 , 45 )........................... Hecalus Stål

- Vertex, pronotum and scutellum with parallel orange or yellow longitudinal bands, forewing green with apical 1/3 brown with white spots in apical and anteapical cells (Figs. 5,10), aedeagus with one or two terminal process, without ventral ridge, dorsal apodeme usually reduced ( Figs. 51–53 ).....................................................
