Figure 7 - The occurrence of the recurrent veinlet through Neuroptera families. The phylogeny of the order is based on that of Yang et al. (2012), but modified according to the most probable relationships of families as discussed by Yang et al. (2012, 2013) and Makarkin et al. (2013).The families that we propose originally lacked the recurrent veinlet are represented in orange; R, families possessing the recurrent veinlet in blue, and those that we propose lost it secondarily in brown. I the ithonoid clade; C Chrysopoidea (the chrysopoid clade); M Myrmeleontoidea (the myrmeleontoid clade); P Psychopsoidea (the psychopsoid clade)
