Key to genera of Otumbini

1. Robust, tegmina and wings absent; pronotum short, not extending beyond the abdomen, or if it does, only slightly.................................................................................................... Platythorus View in CoL

- Slender, generally winged, with the pronotum extending beyond the apex of the abdomen............................ 2

2. Head not protruding, reaching only the same level as the anterior margin of the pronotum; vertex moderately narrow; eyes wider than tall in lateral view. Maxillary palpi segments strongly dilated. Lower margins of the lateral lobes of the pronotum moderately thickening and curving upwards, forming a concave edge......................... Brunneritettix gen. nov.

- Head protruding upwards beyond the anterior margin of the pronotum; vertex narrow or very narrow; eyes in lateral view taller than wide. Maxillary palpi segments moderately or poorly dilated. Lower margin of the lateral lobes of the pronotum projecting perpendicularly sideways............................................................................... 3

3. Vertex very narrow, about half the width of an eye. Lower margin of the lateral lobes of the pronotum, always armed with a conspicuous or uncinated spine.................................................................. Plesiotettix View in CoL

- Vertex narrow, subequal to, or wider than an eye. Lower margin of the lateral lobes of the pronotum variable, with few species having straight spines pointing sideways............................................................. Otumba View in CoL
