Phalangerida is one of the two former suborders of the large marsupial order Diprotodontia. This large and diverse suborder included kangaroos, wallabies, quokkas, possums, gliding possum-like marsupials and others. The much smaller suborder Vombatiformes encompasses only the koalas and wombats. This suborder is no longer considered to accurately describe the diversity in Diprotodontia.
Phalangeridae: brushtail possums and cuscuses
Phalangeriformes has come to replace Phalangerida but does not include the potoroos (Potoroidae), kangaroos and wallabies (Macropodidae) or the musky rat-kangaroo (Hypsiprymnodontidae). These families are now placed in a new suborder named Macropodiformes.
