Allidiostomatinae is a subfamily of beetles in the scarab beetle family, Scarabaeidae. It is distributed in southern South America. Of the 10 species, 7 are endemic to Argentina. Others can also be found in Chile and Peru.[1]

Little is known about the biology of these beetles.[2]

The subfamily was made up of the single genus Allidiostoma until 2009, when a second was erected for the new species Parallidiostoma tricornum.[1]

Genera and species include:
