Distribution: species of Podischnus occur in South America, and one of these, P. agenor (Olivier), extends northward to southern Mexico.
Composition: There are three species in the genus Podischnus (Endrödi 1976b, 1985a).
Diagnosis: Species in the genus may be recognized by the relatively long, subparallel body form; the four teeth on the protibia that project at nearly right angles; bidentate mandibles; and a broadly emarginate clypeus. Horn growth in the males is allometric so that both majors (with large horns) and minors (with small horns) can be found. Male minors tend to resemble females in many of their characters.
Biological notes: Like many other dynastines, adults of Podischnus species lay eggs in the ground where the larvae feed on humus and detritus. Adults probably feed on large-stemmed monocots. Adults are primarily nocturnal and are attracted to lights.
