There is no strong support for any particular sister group relationship, although in a backbone constraint analysis in Percy et al . (2018) , Neophyllurinae subfam. nov. grouped more strongly with Liviinae than Euphyllurinae Crawford, 1914 . The family as defined here differs from that of Burckhardt & Ouvrard (2012) in that it lacks the Diaphorinini (minus Megadicrania and Psyllopsis , which are included here in the Euphyllurinae ). Adults of Liviidae often have a crown of densely spaced apical spurs and immatures have multiple lanceolate or sectasetae.
