Pentodontini is the most diverse tribe within the Dynastinae (rhinoceros beetles), containing over 100 distributed across multiple biogeographic regions. Most genera are restricted to a single biogeographic region. The tribe is characterized by substantial morphological diversity, with generic-level identification often relying on mouthpart in females and secondary sexual characters (horns, claw modifications, antennal club length) in males.

Identification
Generic-level characters within Pentodontini include mouthpart , which is not sexually dimorphic and allows identification of females to ; males often possess secondary sexual characters including obvious cephalic or thoracic horns, modified claws, and antennal club length. Subtribes are distinguished by combinations of these characters: Cheiroplatina, Dipelicina, Pentodontina, and Pseudoryctina.
