“…Postcephalic musculature . In its general configuration the postcephalic musculature is similar to what was described for primary larvae of Mantispa Illiger, 1798 (Jandausch, Beutel, Pohl, Aspöck, et al, ; Jandausch, Beutel, Pohl, Gorb, et al, ), and in the case of the prothorax also to conditions found in Chrysopidae and Coniopterygidae (Rousset, , ).…”

“…Like the skeletal elements the muscle sets of the meso‐ and metathorax are similar. The extrinsic and intrinsic leg muscles are well‐developed and similar to the pattern found in primary larvae of Mantispa (Jandausch, Beutel, Pohl, Aspöck, et al, ; Jandausch, Beutel, Pohl, Gorb, et al, ).…”

“…The main aim of the present study is a detailed documentation of external and internal larval features of Sisyra nigra (Retzius, 1783) using a broad array of imaging techniques. Whereas larval head structures of Neuropterida have been intensively studied (e.g., Beutel et al, ; Beutel & Friedrich, ; Beutel & Ge, ; Gaumont, , ; Jandausch, Beutel, Pohl, Aspöck, et al, ; MacLeod, ; Röber, ; Rousset, ; Sundermeier, ; Wundt, ), information on the anatomy of the postcephalic larval body remains scarce (Jandausch, Beutel, Pohl, Aspöck, et al, ; Jandausch, Beutel, Pohl, Gorb, & Büsse, ; Rousset, ; Rousset, ). Even though the thoracic and abdominal musculature was not reconstructed in full detailed here, as in Jandausch, Beutel, Pohl, Aspöck, et al () and Jandausch, Beutel, Pohl, Gorb, et al (), the general configuration was examined and is described.…”

The morphology of mature larvae of Sisyra nigra was studied and documented with a broad spectrum of techniques. Special emphasis is on the cephalic anatomy and on the digestive tract. Cephalic structures are highly modified, with numerous autapomorphic conditions, including a globular head capsule, an extended area with large cornea lenses, a massive tentorium, a strongly developed prepharyngeal pumping apparatus with a horizontal arrangement of dilators, a sharp bend between the prepharynx and pharynx, and an unusual filter apparatus at the entrance of the large crop. The thoracic and abdominal muscle sets, and the legs are largely unmodified. Postcephalic apomorphies are conspicuous tergal setiferous tubercles, trifid setiferous pleural projections, single pretarsal claws, zigzag-shaped abdominal tracheal gills, and a dense vestiture of setae on the terminal abdominal segments. Mandibulo-maxillary stylets curved outwards are an unusual apomorphy also found in the semiaquatic larvae of Osmylidae. Semiaquatic or aquatic habits and secondarily multisegmented antennae are potential synapomorphies of these two groups and Nevrorthidae (Osmyloidea). A sistergroup relationship between Sisyridae and Nevrorthidae suggests that fully aquatic habits of larvae may be a synapomorphy of both families. A specialized terminal antennal seta is a potential groundplan apomorphy of Neuroptera, with secondary loss in Nevrorthidae and Ithonidae + Myrmeleontiformia, respectively. A trumpet-shaped empodium is likely an apomorphy of Neuroptera excluding Coniopterygidae and Osmyloidea, and the secondary loss an apomorphy of Ithonidae on one hand, and Myrmeleontiformia excl. Psychopsidae on the other. K E Y W O R D S larval anatomy, phylogeny, sponges, Spongillaflies

“…There are several possible systematic interpretations of the fossil, yet all require that several prominent characters have evolved in convergence. Additionally, the internal phylogeny of Neuroptera is still not very stable (Aspöck et al 2012;wANG et al 2017;JANdAusch et al 2018): We here use an established phylogeny with monophyletic Myrmeleontiformia, and for simplicity also monophyletic Hemerobiiformia. It is possible that the latter group is in fact non-monophyletic (see discussion in hAuG et al in review for consequences concerning group names).…”

“…Comparably, the larvae of lacewings have highly modified mouth parts: the lower (posterior) side of the elongated mandible possesses a special groove, which is closed to a functional tube by a likewise elongated maxilla (Aspöck, Plant & Nemeschkal, 2001;Aspöck, Haring & Aspöck, 2012;Beutel, Friedrich & Aspöck, 2010;Jandausch et al, 2018). Hence, lacewing larvae possess a pair of piercing-sucking stylets, formed by interconnected mouth parts.…”

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.
