Dynastes tityus is known by a number of common names, including eastern Hercules beetle, elephant beetle and ox beetle. [1] It was first given a scientific name by Carl Linnaeus, in his 1763 work Centuria Insectorum, where it was called Scarabaeus tityus; when Linnaeus' genus Scarabaeus was divided into smaller genera, S. tityus was renamed Dynastes tityus.

This superfamily includes some of the largest beetles extant today, including rhinoceros beetles, (Dynastinae), the Hercules beetle (Dynastes hercules) and Goliath beetles (Goliathus sp.). The oldest confirmed member of the group is the extinct genus Alloioscarabaeus from the Middle Jurassic period Jiulongshan Formation of Inner Mongolia , China.
