Key to genera of Tumbrinckitettigini
1. Body slender ( Figs. 140 View FIGURE 140 , 141 View FIGURE 141 , 142 View FIGURE 142 , 143 View FIGURE 143 ); space between the eyes in a frontal view as wide as half of an eye ( Figs. 140B View FIGURE 140 , 141D View FIGURE 141 , 142D View FIGURE 142 , 143B View FIGURE 143 ). Mostly winged species; pronotum generally noticeably surpassing the apex of the abdomen and the hind femora ( Figs. 141A View FIGURE 141 , 142A View FIGURE 142 ).................................................................................... 2
- Body generally robust ( Figs. 144 View FIGURE 144 , 145 View FIGURE 145 , 146 View FIGURE 146 ); space between the eyes in a frontal view as wide as 1.5 to 2 times the width of an eye ( Figs. 144C View FIGURE 144 , 145C View FIGURE 145 , 146C View FIGURE 146 , 147C View FIGURE 147 , 148C View FIGURE 148 ). Apterous species (except Hovacris View in CoL ( Fig. 144A View FIGURE 144 )). Pronotum not surpassing the abdomen or the apex of the hind femora................................................................... 3
2. Lateral lobes of pronotal disc always projecting laterally into conspicuous and almost straight spines ( Figs. 140C View FIGURE 140 , 141C View FIGURE 141 ). Body without stripes and covered by small, and usually yellowish points ( Figs. 140 View FIGURE 140 , 141 View FIGURE 141 ).......................... Oxytettix View in CoL
- Lateral lobes of the pronotal disc with variable shapes: triangular or projected into medium-sized spines ( Figs. 142B View FIGURE 142 , 143C View FIGURE 143 ), which can be horizontal or hook-shaped uncinated. Body generally with stripes and points not noticeably contrasted with the coloration of the body ( Figs. 142 View FIGURE 142 , 143 View FIGURE 143 )........................................................... Cryptotettix View in CoL
3. Pronotal disc almost flat with slightly elevated undulations (4 to 5 undulations) ( Fig. 144A View FIGURE 144 ), external lateral carinae finely denticulate ( Fig. 144B View FIGURE 144 ); wings fully developed ( Fig. 144A View FIGURE 144 )............................................. Hovacris View in CoL
- Pronotal disk without dorsal undulations; external lateral carinae smooth; wings absent.............................. 4
4. Median carina of the pronotum rising and forming a hump on the anterior half of the pronotal disc ( Figs. 145A View FIGURE 145 , 146A View FIGURE 146 ). Lateral lobes of the pronotum usually with a triangular spine at the apex ( Figs. 145B View FIGURE 145 , 146B View FIGURE 146 ). Hind femur with spiny lappets on the dorsal margin, and ventrally with small, barely visible, rounded lappets ( Figs. 145A View FIGURE 145 , 146A View FIGURE 146 )............... Charagotettix View in CoL
- Median carina of the pronotum not rising and not forming humps ( Figs. 147A View FIGURE 147 , 148A View FIGURE 148 ). Lateral lobes of the pronotum with a sharp and thin spine at the apex ( Figs. 147B View FIGURE 147 , 148B View FIGURE 148 ). Hind femur without lappets ( Figs. 147A View FIGURE 147 , 148A View FIGURE 148 )..................................................................................................
