Family * Liviidae Löw, 1879

Comments

In both mtg trees, this poorly supported monophyletic or paraphyletic family contains two strongly supported monophyla and one monotypic taxon which we rank as subfamilies: Euphyllurinae , Liviinae and Neophyllurinae subfam. nov. 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.
