2. Undulations of the median carinae of the pronotal disc conspicuous ( Figs. 85A, B ), rounded ( Figs. 86A , 87A ), or spine-shaped ( Fig. 88A ), with two or three main undulations rising in the anterior half of the pronotum..................... Chiriquia

- Undulations of the median carina of the pronotal disc low and moderately elevated, usually with a single undulation in the anterior section of the pronotum ( Figs. 90A , 91A , 92A )....................................................... 3

3. Lower margin of lateral lobes of pronotum rounded ( Fig. 91B ). Genicular and antegenicular teeth conspicuously developed ( Fig. 90B ); external surface of hind femur with tubercles and lappets ( Fig. 91B )......................... Trigonofemora

4. Medial carina of the vertex not protruding in the middle of the eyes in lateral view ( Figs. 92A ). Median carina of the pronotum with two or three small undulations in the anterior section of the pronotum ( Fig. 92B ). Tegmina moderately enlarged, almost ovoid............................................................................. Devrieseium gen. nov.
