The bulk of this species richness belongs to clades located ventrally on within the four megadiverse groups—Coleoptera, Lepidoptera, Hymenoptera, and Diptera— the head capsule of with the remaining lineages relegated to so-called minor orders. Neuropterida are one such lin- some prognathous eage, though when considering their evolutionary history, they could never be considered minor. insects, posterior to the submentum Whether as a single order or under the current tripartite scheme, Neuroptera, Megaloptera, and (labium) and usually Raphidioptera are among the most recognizable and charismatic insects, encompassing the snake- between the postgenae flies, alderflies, dobsonflies, dustywings, antlions, and familiar lacewings among their many other Stem group: relatives (Figure 1). a paraphyletic Here, we summarize the current consensus on relationships among the main lineages of Neu- assemblage, excluding ropterida, with brief synopses of their evolution, diversity, and biology. Current syntheses of the crown group; it is molecular and morphological data are converging on relationships that harken back to Cyril sufficient to denote such taxa as Withycombe (1898–1926) (123). Thus, a recurrent theme in modern neuropterology is that stem-group X, rather many historical schemes are supported by our contemporary science. This does not imply a than proliferate need for a retrograde reclassification of Neuroptera but instead a renewed appreciation of our uninformative, minute intellectual forebears. In addition, we have attempted to provide some foils against which future taxa of identical research might joust, in the hopes of stirring new advances in our understanding of lacewing categorical rank to their associated crown evolution. group or mislead by regarding a paraphyletic taxon to be the sister to the MONOPHYLY AND RELATIONSHIPS AMONG crown group NEUROPTERID ORDERS Crown group: The monophyly of Neuropterida has not been a matter of serious debate, and every robust, modern a monophyletic, more attempt at estimating relationships among the principal lineages of Holometabola has recovered recently evolved the clade (70, 110) and supported it as sister to Coleoptera or Coleoptera + Strepsiptera (70, 89, lineage 101, 102, 110). Opinion about the relationships among the three orders, by contrast, has gone back and forth over recent decades, converging upon a Megaloptera + Neuroptera clade (Eidoneu- roptera) relative to Raphidioptera (111, 120). The alternative of Raphidioptera + Megaloptera was argued for owing to shared telotrophic ovarioles, grooming behavior, specializations of the tho- rax, and a gula (46, 47); however, these are inconsistent in light of current phylogenetic estimates and the homology of those varied sclerites lumped as gulae in distant taxa, and the polarity and distribution of telotrophic ovarioles are suspect (20, 38). For now, the Eidoneuroptera hypothesis is the one most widely supported by diverse sources of data (18, 111, 120, 126). Annu. Rev. Entomol. 2018.63:531-551. Downloaded from www.annualreviews.org The Neuropterida as a whole are today largely relict but not primitive. In fact, most lineages of Holometabola diverged early in the Carboniferous or latest Devonian (70, 73, 110), with the Access provided by Texas A&M University - College Station on 01/28/18.

Records and calibrated estimations are for stem groups, whereas taxa that we might ascribe to crown-group Neuropterida are not known until the Early Permian and most extant families not known until the Mesozoic (Figure 2), much as is true for other holometabolan lineages (34). Two extinct groups from the Early to Late Per- mian, Permoberothidae and Permithonidae (Protoneuroptera), are most likely representatives of earlier stem-group eidoneuropterans (34, 90). The group is heterogeneous, however, and some permithonids may be more closely related to Neuroptera. Some of these species had been impli- cated as stem-Megaloptera but lack any shared features with Megaloptera (90). Modern genera and species are nonetheless relict in that the phylogenetic diversity, biological and morphological disparity, and breadth of distribution across the clade have decreased over geological time. 532 Engel · Winterton · Breitkreuz EN63CH27_Engel ARI 20 November 2017 14:5 ab cd e e a a d i d e i i NNemopteridae l a SSisyridae d l i d e i e i e s l m h a AAscalaphidae c y a d p o i p s r o d l e c i a n y a d p IInocellidae i a RRaphidiidae r t SSialidae la a o e NNymphidae p e CCorydalidae e y r a e h i m d id a id r d p a i a a h e l n i e i o d DDilaridae a th ae e IIthonidae d pi tis an o MMantispidae e f da psi cho PPsychopsidaesy CChrysopidaehry sopidae MMyrmeleontidae yrm ele ont idae n ae g id th RRhachiberothidae ro e h e CConiopterygidae BBerothidae a a id o c i n h b e a i i o o b r d e i p e e r m h t o t a e e r t HHemerobiidae d r h o i y r l i g d v y m i a h e d m e NNevrorthidae s a e OOsmylidae Annu.
