Key to the South American genera of Lepturini  

1. Pronotum with sides sinuate, hind angles not toothed–appearing; humeri obliquely truncated.................... ............................................................................................................................. Cyphonotida Casey, 1913  

- Pronotum campanuliform, base strongly impressed on each side, giving hind angles a toothed appearance; rounded humeri............................................................................................................................................ 2

2. Intercoxal process of mesosternum narrow, from 1 / 3 to 1 / 2 the diameter of the coxal cavity, without projection; metatarsomere 1 longer than the others combined......................................................................... 3

- Intercoxal process of mesosternum broad, at least 2 / 3 the diameter of the coxal cavity, and projecting beyond; metatarsomere 1 as long as or shorter than the others combined................................................. 4

3. Elytra parallel-sided or slightly expanded to apices; ventrite 5 without sexual dimorphism........................ ................................................................................................... Lycochoriolaus Linsley & Chemsak, 1976  

- Elytra tapering to apex; males often with the ventrite 5 strongly inflated at the sides.................................. ............................................................................................................... Strangalia Audinet   – Serville, 1835

4. Elytra parallel-sided, without dorsal carinae ................................................ Megachoriolaus Linsley, 1970  

- Elytra expanded apically, dorsal surface with carinae....... Euryptera Lepeletier & Audinet   –Serville, 1828
