Phylogeny of pleasing lacewings (Neuroptera: Dilaridae) with a revised generic classification and description of a new subfamily

The phylogeny of pleasing lacewings (Neuroptera: Dilaridae) is reconstructed for the first time based on morphological data using all fossil and extant genera. Accordingly, a revised generic classification of Dilaridae is proposed, with a new subfamily (i.e. Berothellinae subfam.n. ) erected based on its remarkably different morphological features from the other dilarid subfamilies. A revision of all dilarid genera is presented, including descriptions of some little‐known species from Asia and Mid‐Cretaceous Burmese amber. New genera and species herein described include Berothella holzschuhi U. Aspöck, Liu & H. Aspöck, sp.n. , Cretodilar burmanus Liu & Zhang, gen. et sp.n. , Dilar cretaceus Liu & Zhang, sp.n. , Neonallachius orientalis Liu, U. Aspöck & H. Aspöck, sp.n. and Neonallachius thailandicus Liu & Winterton, sp.n. Two new combinations, i.e. Neonallachius krooni (Minter, 1986), comb.n. and Neonallachius ponomarenkoi (Zakharenko, 1991), comb.n. , are proposed. Evolutionary patterns of some important characters and the historical biogeography of Dilaridae are also discussed.
