Digitonthophagus is a of scarab beetles in the Scarabaeidae, tribe Onthophagini. The genus was established by Balthasar in 1959 and was historically treated as a subgenus of Onthophagus by some authorities. A comprehensive taxonomic review was published in 2017, resulting in the description of numerous new . The genus currently comprises 16 recognized species distributed across the Afrotropical, Oriental, and Palaearctic regions. Members are dung beetles that exhibit the typical scarabaeine of burial for larval provisioning.

Identification
Digitonthophagus can be distinguished from related within Onthophagini by genitalic characters and specific morphological features of the and pronotum. The 2017 revision by Génier established diagnostic characters separating this genus from Onthophagus, including details of the clypeal structure and male genitalia. Species-level identification requires examination of these structures, as external shows considerable variation and overlap.
