Key to genera of Pterotettigini

1. Lower margin of the lateral lobes of the pronotum produced into a conspicuous spine ( Fig. 160C ). Midline of the pronotum and anterior section of the pronotal disc rising into a hump ( Fig. 160A ). Wings absent........................... Ocytettix

- Lower margin of the lateral lobes of the pronotum subtriangular, rounded, or acute but not produced as a prolonged spine ( Figs. 156B , 158B ). Midline of pronotum slightly wavy or forming two conspicuous crests ( Figs. 156A , 158A , 159A ). Wings present.............................................................................................. 2

2. Lateral carinae of the vertex of similar height to the median carina ( Figs. 156C , 157C ). Midline of the pronotum elevated ( Fig. 156A , 157A ), and the lower margin of the lateral lobes of the pronotum obliquely truncated, rarely pointed ( Figs. 156B , 157B )....................................................................................... Pterotettix

- Lateral carinae of the vertex conspicuously protruding in the form of two “horns” ( Figs. 158C ). Midline of the pronotum elevated into two conspicuous crests ( Figs. 158A , 159A ), and the lower margin of the lateral lobes of pronotum acute ( Figs. 158B , 159B )....................................................................... Tetticerus stat. resurr.
