- Key to the genera of adult Cyclocephalini of Colombia 1. Protarsomeres in males enlarged; external claws larger than internal. Females with protarsomeres and claws simple. Clypeal length subequal to or long- er than length of frons; apex parabolic, quadrate, weakly emarginated, or rounded. Metatibia semicircular in cross section........................................ 2 – Protarsomeres in males and females simple, not enlarged; tarsal claws simple. Clypeal length shorter than length of frons; apex trapezoidal (Fig. 8). Metatibia flattened dorsoventrally, not semicircular in cross section..................................................................................................... Stenocrates Burmeister 2. Propygidium with numerous long setae........................... Chalepides Casey – Propygidium without long setae................................................................. 3 3. Clypeus with apex acute or narrowly parabolic........................................... 4 – Clypeus with apex rounded, truncate, trapezoidal, or emarginate............... 5 4. Clypeus with apex acuminate (Fig. 9). Mentum with apex emarginate, surface not furrowed in apical third. Base of pronotum with marginal bead................................................................................................ Mimeoma Casey – Clypeus with apex narrowly parabolic (Fig. 10). Mentum with apex deeply emarginated, surface with furrow in apical third. Base of pronotum without marginal bead............................................................ Ancognatha Erichson 5. Clypeus trapezoidal or subtrapezoidal. Anterior margin of pronotum weakly produced anteriorly at middle (Fig. 11).......................... Dyscinetus Harold – Clypeus quadrate,rectangular or parabolic. Anterior margin of pronotum not produced anteriorly at middle.................................................................... 6 6. Clypeus with sides usually divergent from base, apex broadly rounded (Fig. 12). Maxilla without teeth (except for Aspidolea fuliginea)............ Aspidolea Bates – Clypeus with sides parallel or convergent from base, apex rounded, truncate or emarginate. Maxilla with visible teeth.................................................... 7 7. Clypeus with sides convergent, apex rounded, parabolic or emarginated (Fig. 13). Males with protarsus enlarged......................
