Liviidae is a family of plant lice (order Hemiptera), with about 19 genera.
There have been various classifications of Psylloidea including that of Burckhardt and Ouvrard (2012); in the latest (2021) review, three monophyletic subfamilies were identified:
Authority: Burckhardt D, Ouvrard D, Percy DM (2021)
