“…Nipponosialis kumejimae is the sister to the monophyletic group including N. jezoensis + N. kuwayamai and most Sialis species. The non‐monophyly of Nipponosialis and its present relationships with Sialis are concordant with the synonymization of Nipponosialis under Sialis proposed by New and Theischinger (). All Old World Sialis and most Nearctic Sialis ( S. americana + S. glabella excluded) are monophyletic and are supported by the feebly prominent male compound eyes (char.…”

“…Further, they are poor fliers, and remain in the same general area where the larvae occurred (Flint et al., ). In contrast to corydalids, sialid adults are mostly diurnal and seldom captured by light (New and Theischinger, ). Although some alderfly species from Palaearctic and Nearctic realms are readily found in the field, most species from other zoogeographical realms are extremely rare in collections.…”

“…() attempted to reconstruct the intergeneric phylogeny of Sialidae, including both extant and fossil genera based on only wing venation characters, but failed to obtain well resolved results. Therefore, due to the poorly studied intergeneric and interspecific relationships of the Sialidae, the generic classification remains obscure and severely in need of revision, a fact that has been repeatedly lamented by numerous authors (New and Theischinger, ; Penny, ; Whiting, ; Contreras‐Ramos, ; Liu et al., ; Price et al., ).…”

Phylogeny of the family Sialidae (Insecta: Megaloptera) inferred from morphological data, with implications for generic classification and historical biogeography

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.

“…Its presence is a potential autapomorphy of Megaloptera (Röber 1942). However, the specific conditions vary distinctly in both constituent families, and mandibular dimorphism is not generally present in Chauliodinae (Maki 1936;New and Theischinger 1993).…”

External and internal head structures of Osmylus fulvicephalus were examined and described in detail. Exoand endoskeleton, musculature, elements of the central nervous system and tracheae are compared to conditions found in other groups of Neuropterida and other endopterygote lineages. Thirty-six adult cephalic characters were compiled, combined in a datamatrix with 64 characters of the larval head, and analysed cladistically. Mainly because many data on adults remain missing, most branches in the cladogram are mostly or exclusively supported by larval features. The shortening of the mesal mandibular wall and the resulting anterior shift of the adductor tendon possibly constitute an adult groundplan apomorphy of Neuropterida. Raphidioptera and Megaloptera share distinct prognathism and the presence of a sclerotised gula. However, the orthognathous head and the absence of a gula resulted as autapomorphies of Neuroptera in our analyses. Further potential autapomorphies are the asymmetry of the mandibles as well as the respective presence of dorsolateral furrows on the head capsule, of a shovel-like extension on the ventral mandibular cutting edge, and of a row of stiff hairs on the mandible's ventral surface. The systematic affinities of Osmylidae remain ambiguous. Osmylus is mainly characterised by plesiomorphic features of the adult head such as a complete endoskeleton, long filiform antennae, largely unmodified orthopteroid mouthparts, and particularly the nearly complete set of muscles. The placement with a clade also comprising Hemerobiidae and Chrysopidae is poorly supported. The presence of a dense vestiture of long microtrichia on the distal galeomere resulted as a synapomorphy of the three families. An apparent plesiomorphy preserved in Osmylus but absent in all other groups of Neuroptera is the presence of well developed ocelli. The present study underlines the severe shortage of detailed morphological data on the adults. Intensive study of adult structures is required for a solid reconstruction of the phylogeny of Neuropterida, especially of the hemerobiform lineage of Neuroptera.

“…egaloptera é uma pequena ordem de insetos aquáticos holometábolos, com aproximadamente 348 espécies mundialmente distribuídas (Contreras-ramos 2011), caracterizados por um estágio larval exclusivamente aquático e por adultos alados com cabeça prognata e área anal da asa posterior larga (new & theisChinger 1993). Atualmente a ordem é constituída pelas famílias Corydalidae e Sialidae, com Corydalidae estando subdividida nas subfamílias Corydalinae e Chauliodinae (Contreras-ramos 2011).…”
