Phylogeny of Chrysopidae (Neuroptera), with emphasis on morphological trait evolution

Abstract

Abstract We present a phylogeny of Chrysopidae inferred from combining molecular and morphological data. Apochrysinae were recovered as sister to the rest of the family (Nothochrysinae and Chrysopinae). The monogeneric tribe Nothancylini is confirmed as sister to the remaining Chrysopinae. The other four tribes are grouped in two clades: Belonopterygini + Leucochrysini and Ankylopterygini + Chrysopini. The Nineta-group is herein transferred from Chrysopini to Ankylopterygini. Within the diverse and species-rich Chrysopini we recognize five genus-group clades: Chrysopa, Chrysoperla, Chrysopodes, Eremochrysa and Meleoma generic groups. The mapping of characters, such as the parameres, the tignum, the im cell or the tibial spurs, on the phylogeny provides insights into the evolution of these traits in the family. In addition, we propose the following taxonomic changes to the classification of the family: the inclusion of Chrysopidia, Nineta and Tumeochrysa in the tribe Ankylopterygini, and the synonymization of Furcochrysa with Chrysopa.
