Ranolus is a genus of beetles in the family Dermestidae from Southeast Asia and Oceania.
[1] It was originally described as a subgenus of Attagenus, containing only the species Ranolus cavernicola.
It was later found to be a separate genus, and was placed in its own tribe, Ranolini, along with Orphilodes.
A second species, Ranolus tenebricola, was described by Jiří Háva in 2014.
[2] Orphilodes was later synonymized with Ranolus.
