Mesozoic chrysopid-like Planipennia: A phylogenetic approach (Insecta: Neuroptera)

Abstract

The Mesozoic chrysopid-like Planipennia are revised and several new genera and species are described. The new superfamily Chrysopoidea is proposed for the extant and fossil Chrysopidae, and the fossil families Liassochrysidae n. fam., Allopteridae Zhang 1991 n. sensu, Mesochrysopidae Handlirsch, 1906 n. sensu, Tachinymphidae n. fam., and Limaiidae Martins-Neto and Vulcano 1989 n. sensu. A phylogenetic analysis of the Chrysopoidea is proposed, based on the wing venation characters. With at least the four families Allopteridae, Mesochrysopidae, Tachinymphidae, and Chrysopidae, showing different wing venation patterns, the systematic diversity and morphological disparity of the Chrysopoidea are maximal during the Late Jurassic and Early Cretaceous. The Mesozoic family Limaiidae was still present during the Paleocene/Eocene suggesting a minimal impact on the Chrysopoidea of the crisis of the diversity at the K-T boundary. Other Cenozoic Chrysopoidea can be attributed to the Chrysopidae sensu stricto. © 2005 Taylor & Francis Group, LLC.
