“…In larvae of the megalopteran ingroup Corydalidae, these processes are elongate and tapering distally and are not subdivided into several elements (Gepp, 1984). In larvae of the megalopteran ingroup Sialidae these processes also taper distally, but are further subdivided into multiple elements (New & Theischinger, 1993;Bowles & Contreras-Ramos, 2016). The abdomen processes in Megaloptera can bear numerous setae, very similar to the condition in the fossil larva.…”

“…Yet, in some larvae of Sialidae this unpaired structure is strongly elongated (unfortunately termed 'terminal filament') and tapering distally ( Fig. 5A; Bowles & Contreras-Ramos, 2016). In fossil representatives of the lineage it is less elongated, but also tapering distally ( Fig.…”

Holometabola is a hyperdiverse group characterised by a strong morphological differentiation between early post-embryonic stages (= larvae) and adults. Adult forms of Holometabola, such as wasps, bees, beetles, butterflies, mosquitoes or flies, are strongly differentiated concerning their mouth parts. The larvae most often seem to retain rather plesiomorphic-appearing cutting-grinding mouth parts. Here we report a new unusual larva preserved in Burmese amber. Its mouth parts appear beak-like, forming a distinct piercing mouth cone. Such a morphology is extremely rare among larval forms, restricted to those of some beetles and lacewings. The mouth parts of the new fossil are forward oriented (prognathous). Additionally, the larva has distinct subdivisions of tergites and sternites into several sclerites. Also, the abdomen segments bear prominent protrusions. We discuss this unusual combination of characters in comparison to the many different types of holometabolan larvae. The here reported larva is a new addition to the ‘unusual zoo’ of the Cretaceous fauna including numerous, very unusual appearing forms that have gone extinct at the Cretaceous–Palaeogene boundary.

“…Endemism in Megaloptera is fairly common, even at the genus level (e.g., Chloroniella in South Africa, Dysmicohermes and Orohermes in western North America, Madachauliodes in Madagascar, and Apochauliodes and Austrosialis in Australia). Regarding the taxonomic knowledge of the larval stages, mature larvae are described for six genera of Corydalinae ( Acanthacorydalis , Chloronia , Corydalus , Neoneuromus , Platyneuromus , and Protohermes ), 13 genera of Chauliodinae ( Apochauliodes , Archichauliodes , Chauliodes , Dysmicohermes , Madachauliodes , Neochauliodes , Neohermes , Nigronia , Orohermes , Parachauliodes , Platychauliodes , Protochauliodes , and Taeniochauliodes ), and seven genera ( Austrosialis , Haplosialis , Ilyobius , Indosialis , Leptosialis , Sialis , and Stenosialis ) of Sialidae [4,16,17,18].…”

Megaloptera belong to a large monophyletic group, the Neuropteroidea, together with Coleoptera, Strepsiptera, Raphidioptera, and Neuroptera. With the latter two, this order constitutes the Neuropterida, a smaller monophyletic subset among which it is the only entirely aquatic group, with larvae of all species requiring submersion in freshwater. Megaloptera is arguably the oldest extant clade of Holometabola with aquatic representatives, having originated during the Permian before the fragmentation of Pangea, since about 230 Ma. It includes 54 genera (35 extant and 19 extinct genera), with 397 extant described species and subspecies. Recent Megaloptera are divided into two families: Corydalidae (with subfamilies Corydalinae—dobsonflies and Chauliodinae—fishflies) and Sialidae (alderflies), both widely yet disjunctively distributed among zoogeographical realms. All species of Megaloptera have aquatic larvae, whereas eggs, pupae, and adults are terrestrial. The anatomy, physiology, and behavior of megalopteran larvae are specialized for an aquatic predatory habit, yet their ecological significance might still be underappreciated, as their role in food webs of benthic communities of many temperate and tropical streams and rivers is still understudied and largely unquantified. In many freshwater ecosystems, Megaloptera larvae are a conspicuous benthic component, important in energy flow, recycling of materials, and food web dynamics.

“…Among these papers, there are the first descriptions of the larvae representing four Asian endemic genera, i.e. Acanthacorydalis (Cao et al, 2013), Neoneuromus (Cao et al, 2016), Anachauliodes (Tu et al, 2019), and Indosialis (Bowles & Contreras-Ramos, 2016). Besides, there are a few reports on the larvae of some species of Chloroniella (Martins & Contreras-Ramos, 2020), Corydalus (Azevêdo & Hamada, 2006, 2007, and Ilyobius (Archangelsky et al, 2017).…”

In the first twenty years of the publication of Zootaxa, more than two hundred papers have appeared in this journal that address the Neuropterida, which collectively includes the [Neuroptera+Raphidioptera]+Megaloptera sections (initially “Minor orders” section). A dozen submitted manuscripts were rejected before the review process, and another dozen submissions were rejected following the peer review process. Additional content and general submission history of these contributions is summarized here. These various contributions highlight the growing body of research on the Neuropterida and the importance of Zootaxa as a key journal for publishing and disseminating this research.
