What superfamilies does Staphyliniformia belong to?

Staphyliniformia is a large infraorder of beetles. It contains over 70,000 described species from all regions of the world. Most species occur in moist habitats - various kinds of rotting plant debris, fungi, dung, carrion, many live in fresh water.

Staphyliniformia belongs to the suborder Polyphaga and is usually given an infraorder or series rank. It contains three superfamilies:

Histeroidea, including the clown beetles.
Hydrophiloidea, including the water scavenger beetles
Staphylinoidea, including antlike stone beetles, carrion beetles, and rove beetles.
Some recent studies also include the superfamily Scarabaeoidea (infraorder Scarabaeiformia), forming together the so-called Hydrophiloid lineage.[2][3] A sister group relationship of Hydrophiloidea and Histeroidea is strongly supported.[4]
Staphyliniformia, an infraorder of beetles, belongs to superfamilies Histeroidea, Hydophiloidea, and Staphyliniodea. Current studies also include Staphyliniformia in the superfamily Scarabaeoidea.
