Sialidae (alderflies) is a family of the holometabolous insect order Megaloptera, with ca. 75 extant species in eight genera distributed worldwide. Alderflies are a group of “living fossils” with a long evolutionary history. The oldest fossil attributed to Sialidae dates back to the Early Jurassic period. Further, the global distribution of modern‐day species shows a remarkably disjunctive pattern. However, due to the rareness of most species and scarcity of comprehensive taxonomic revisions, the phylogeny of Sialidae remains largely unexplored, and the present classification system is in great need of renewal. Here we reconstruct the first phylogeny for Sialidae worldwide based on the most comprehensive sampling and broadest morphological data ever presented for this group of insects. All Cenozoic alderflies belong to a monophyletic clade, which may also include the Early Jurassic genus †Dobbertinia, and the Late Jurassic genus †Sharasialis is their putative sister taxon. Two subfamilies of Sialidae are proposed, namely †Sharasialinae subfam. nov. and Sialidinae. Austrosialis is the sister of all other extant genera, an assemblage which comprises three monophyletic lineages: the Stenosialis lineage, the Ilyobius lineage, and the Sialis lineage. The revised classification of Sialidae is composed of 12 valid genera and 87 valid species. Ilyobius and Protosialis are recognized as valid generic names, while Nipponosialis is treated as a synonym of Sialis. Reconstruction of the ancestral area proposes a global distribution of alderflies in Pangaea before their diversification. The generic diversification of alderflies might have occurred before the breakup of Pangaea, but the divergence of some lineages or genera was probably promoted by the splitting of this supercontinent.

“…The diversification patterns that gave origin to the incredibly diversified fauna of Corydalidae in the Oriental region are of great interest, yet are still poorly understood. Previous studies that attempted to elucidate the diversification of dobsonflies utilized morphology‐based phylogenies to infer their evolution and historical biogeography (Yang & Liu, ; Liu et al ., , , , ). These studies indicated an Indian origin for the Oriental Corydalidae, with northeastern India and adjacent areas, specifically, being the diversification centre for this group.…”

The dobsonfly genus Neoneuromus van der Weele is endemic to the Oriental region. Species possess highly variable body and wing colouration and markings, not only among species but also among conspecific individuals of certain species. This stark polymorphism hinders accurate species identification, and obscures an undocumented species diversity as well as our understanding of the evolutionary history of this genus. We used multiple methods of molecular identification combined with morphological evidence to delimitate species, circumscribing a total of 13 species in Neoneuromus. Five new species are herein described: Neoneuromus indistinctus Liu, Hayashi & Yang, sp.n., Neoneuromus maculatus Liu, Hayashi & Yang, sp.n., Neoneuromus niger Liu, Hayashi & Yang, sp.n., Neoneuromus similis Liu, Hayashi & Yang, sp.n. and Neoneuromus vanderweelei Liu, Hayashi & Yang, sp.n. The dated phylogeny with reconstructed ancestral areas indicates an initial divergence of Neoneuromus during the mid‐Eocene. A broad area including northeastern India and northern Indochina could be a centre for early divergence of the genus, while complex dispersal and vicariance events dating from the late Eocene to the Pliocene probably shaped the present diversity and distribution of the genus. Our ancestral character state reconstruction suggests that the pale and dark colour forms among different species, or conspecifics, could evolve rapidly and that changes in colouration could be driven by species‐specific mate recognition.

Fishflies (Corydalidae: Chauliodinae) with a total of ca. 130 extant species are one of the major groups of the holometabolous insect order Megaloptera. As a group which originated during the Mesozoic, the phylogeny and historical biogeography of fishflies are of high interest. The previous hypothesis on the evolutionary history of fishflies was based primarily on morphological data. To further test the existing phylogenetic relationships and to understand the divergence pattern of fishflies, we conducted a molecule-based study. We determined the complete mitochondrial (mt) genomes of two Australian fishfly species, Archichauliodes deceptor Kimmins, 1954 and Protochauliodes biconicus Kimmins, 1954, both members of a major subgroup of Chauliodinae with high phylogenetic significance. A phylogenomic analysis was carried out based on 13 mt protein coding genes (PCGs) and two rRNAs genes from the megalopteran species with determined mt genomes. Both maximum likelihood and Bayesian inference analyses recovered the Dysmicohermes clade as the sister group of the Archichauliodes clade + the Protochauliodes clade, which is consistent with the previous morphology-based hypothesis. The divergence time estimation suggested that the divergence among the three major subgroups of fishflies occurred during the Late Jurassic and Early Cretaceous when the supercontinent Pangaea was undergoing sequential breakup.
