Key to Genera of Agyrtodini  of Latin America (modified from Peck et al., 1998a and Salgado, 2015a)

1a Epistomal suture absent; lacinia with large dense rasp-like brush; body ovoid, pronotum widest at or very near base; mesosternum with mid-longitudinal carina................................................................. Agyrtodes 

1b Epistomal suture present, usually with small “stem”; lacinia with normal setose brush; body form variable, pronotum usually widest before base; mesosternum carinate or not............................................................. 2

2a Mesosternum not carinate............................................................................... 3

2b Mesosternum carinate.................................................................................. 6

3a Surfaces of pronotum and elytra extremely uneven, with many bumps and depressions; elytra without transverse striolations; pronotum widest before middle, sides sinuately narrowed posteriorly, hind angles right; basal segment of male mesotarsus with large tooth as well as tenent setae................................................................. Ragytodina 

3b Surfaces of pronotum and elytra more or less even, without bumps, with few or no depressions; elytra transversely striolate; pronotal shape variable, generally widest at or behind middle, sides not notably sinuate, hind angles obtuse; male mesotarsus never with teeth, with or without tenent setae on basal 1 – 2 segments............................................. 4

4a Pronotum evenly covered with coarse, deep punctures separated by about their own diameters, surface between punctures smooth and shining; male mesotarsus with basal 2 segments expanded and bearing tenent setae................ Eupelates 

4b Pronotal punctation variable, generally not coarsely and densely punctate or punctures shallow, surface between punctures variable but often microsculptured and dull; male mesotarsus usually with at most basal segment expanded and bearing tenent setae............................................................................................... 5

5a Male with elevated spinose process on ventral edge of mesofemur, and pair of curved spinose processes near posterior edge of ventrite VII (penultimate visible ventrite); aedeagal parameres glabrous................................. Dasypelates 

5b Male without elevated spinose processes on femora and abdominal ventrites; aedeagal parameres setose near apex.................................................................................................. Chiliopelates 

6a Body somewhat convex; low mesoventral keel; male mesotarsi slender; elytral longitudinal striae with visible sulci................................................................................................. Karinapelates 

6b Body rounded; high mesoventral keel; male mesotarsi expanded; elytral longitudinal striae without sulci....... Dontipelates
