[show abstract][hide abstract] ABSTRACT: Two different patterns of wing venation are currently supposed to be present in each of the three orders of Paraneoptera. This is unlikely compared with the situation in other insects where only one pattern exists per order. We propose for all Paraneoptera a new and unique interpretation of wing venation pattern, assuming that the convex cubitus anterior gets fused with the common stem of median and radial veins at or very near to wing base, after separation from concave cubitus posterior, and re-emerges more distally from R + M stem. Thereafter, the vein between concave cubitus posterior and CuA is a specialized crossvein called "cua-cup," proximally concave and distally convex. We show that despite some variations, that is, cua-cup can vary from absent to hypertrophic; CuA can re-emerge together with M or not, or even completely disappear, this new interpretation explains all situations among all fossil and recent paraneopteran lineages. We propose that the characters "CuA fused in a common stem with R and M"and "presence of specialized crossvein cua-cup" are venation apomorphies that support the monophyly of the Paraneoptera. In the light of these characters, we reinterpret several Palaeozoic and early Mesozoic fossils that were ascribed to Paraneoptera, and confirm the attribution of several to this superorder as well as possible attribution of Zygopsocidae (Zygopsocus permianus Tillyard, 1935) as oldest Psocodea. We discuss the situation in extinct Hypoperlida and Miomoptera, suggesting that both orders could well be polyphyletic, with taxa related to Archaeorthoptera, Paraneoptera, or even Holometabola. The Carboniferous Protoprosbolidae is resurrected and retransferred into the Paraneoptera. The genus Lithoscytina is restored. The miomopteran Eodelopterum priscum Schmidt, 1962 is newly revised and considered as a fern pinnule. In addition, the new paraneopteran Bruayaphis oudardi gen. nov. et sp. nov. is described fromthe Upper Carboniferous of France (see Supporting Information).

Although the new genus has the principle synapomorphies of Calopterygoidea, it possesses a unique structure (possible reversal) in the pattern of vein RP1/2.
[show abstract][hide abstract] ABSTRACT: The first Chinese and English representatives of the Mesozoic gomphid family Proterogomphidae are described, respectively Lingomphus magnificus gen. et sp. nov., and Cordulagomphus europaeus sp. nov. A phylogenetic analysis of the most ‘basal’ gomphid lineages is proposed, showing the monophyly of the Proterogomphidae and the position of Lingomphus as sister group of all other representatives of this family. C. europaeus is the first Eurasiatic representative of the subfamily Cordulagomphinae that was previously restricted to the Lower Cretaceous of Crato Formation (South America). The Proterogomphidae has a known distribution very similar to those of several other Lower Cretaceous insect groups, viz. Asia, Europe, and South America, showing that the distribution of the climates and land masses at that time was not a ‘serious’ impediment for the displacements of these organisms.

[show abstract][hide abstract] ABSTRACT: The Mantophasmatodea is the most recently discovered insect order. The fossil records of all other 'polyneopteran' orders extend far in the past, but the current absence of pre-Cenozoic fossils of the Mantophasmatodea contradicts a long evolutionary history, which has to be assumed from the morphological distinctness of the group. In this paper, we report the first Mesozoic evidence of a mantophasmatodean from the Middle Jurassic of Daohugou, Inner Mongolia, China. Furthermore, the new fossil shares apomorphic characters with Cenozoic and recent Mantophasmatodea, suggesting a longer evolutionary history of this order.
[show abstract][hide abstract] ABSTRACT: The Middle Jurassic Archipsylla sinica sp. n. is the first record of the enigmatic Mesozoic family Archipsyllidae from China. This well-preserved Chinese material bears several apomorphies allowing an attribution of this family to the Psocodea. The presence of four-segmented tarsi in Archipsyllidae suggests that the reduction in number of tarsomeres occurred independently at least two times in the modern paraneopteran lineages Psocodea (“Psocoptera” + Phthiraptera) and Condylognatha (Thysanoptera + Hemiptera).RésuméArchipsylla sinica nov. sp. du Jurassique moyen est le premier fossile chinois connu de la famille énigmatique mésozoïque Archipsyllidae. Ce matériel chinois, très bien conservé, montre plusieurs apomorphies qui permettent l’attribution de cette famille aux Psocodea. La présence de tarses avec quatre articles chez les Archipsyllidae suggère que la réduction du nombre de tarsomères s’est produite indépendamment chez les deux lignées modernes de Paranéoptères (Psocodea et Condylognatha).

The new genus is characterized by the particular shape of its pronotum, its hind leg, and stridulatory veins that only concern the cubital area but not the anal area, unlike in other Chifengiinae.

New ‘Grylloblattida’ related to the genus Prosepididontus Handlirsch, 1920 in the Middle Jurassic of China (Insecta: Geinitziidae). Alcheringa 32, 395–403. ISSN 0311-5518.On the basis of well-preserved nearly complete specimens, two new genera and species Sinosepididontus chifengensis and Megasepididontus grandis, both closely related to the Early Jurassic geinitziid genus Prosepididontus, are described. The new material was collected from the Middle Jurassic Jiulongshan Formation near the Daohugou Village, Ningcheng County, Inner Mongolia, northeast China. New body and leg structures are described for these Chinese taxa. They were previously unknown in other Geinitziidae. The new data indicate that the extinct ‘Grylloblattida’ contained heterogenous groups.
[show abstract][hide abstract] ABSTRACT: Juralibellula ningchengensis gen. nov., sp. nov., type species of the new family Juralibellulidae, is the oldest record of the clade Cavilabiata. As sister group of the Neobrachystigmata in the new clade Paraneobrachystigmata, it demonstrates the presence of this relatively much derived subclade in the Middle Jurassic, suggesting a great antiquity for the Cavilabiata.

[show abstract][hide abstract] ABSTRACT: A new genus Nodalula gen. nov. and species Nodalula dalinghensis gen. et sp. nov. is described on the basis of a nearly complete specimen from the Lower Cretaceous of North-east China. Its special pattern of wing venation differs from those of the known Mesozoic Cavilabiata genera and allows us to include it in the new family Nodalulaidae within the Neobrachystigmata.
[show abstract][hide abstract] ABSTRACT: A new genus of Bittacidae, Mongolbittacus gen. n., based on Mongolbittacus daohugouensis sp. n., is described from the Middle Jurassic of Inner Mongolia, China. The presence of a four-winged specimen enables documentation of the intraspecimen variation of wing venation. Mongolbittacus appears to be related to the genera Orobittacus, Microbittacus, Mesobittacus, Preanabittacus, Anabittacus, Baissobittacus, Liaobittacus, Jichoristella and Antiquanabittacus because of the presence of three synapomorphies, i.e. MP4+CuA1+2 simple; Kreuz der Bittaciden (rp3+4 + ma–mp1+2 and mp1+2–mp3 crossveins) not aligned; and crossvein c–sp absent.

This is the first fossil record of a soldier fly so far described from China. It was armed with a specialized mouth part (proboscis and labella) and its huge body and short wings imply that it was a pollen eater and a poor flier.

Their close affinities with the genus Pternopteron (Dogger of Kirgizia) support a similar age for the Daohugou fauna.
[show abstract][hide abstract] ABSTRACT: Parapetala liaoningensis gen. et sp. nov. is described from the Lower Cretaceous of China. It has a very basal position in the clade Aeshnoptera (Odonata. Petalura, Spec. 2 (1996) 402), basal or close to the Upper Jurassic family Mesuropetalidae. This discovery confirms the high diversity of this group of dragonflies during the Late Jurassic–Early Cretaceous, suggesting rapid evolution of this clade in the Early or Middle Jurassic.

[show abstract][hide abstract] ABSTRACT: A fossil mayfly nymph Caenoephemera shangyuanensis, gen.nov., sp.nov., discovered in the lower part of the Upper Jurassic – Lower Cretaceous Yixian Formation of Jianshangou, Beipiao district, West Liaoning, China, is described. It has several archaic features typical of Paleozoic mayfly nymphs, such as 5 tarsal segments and hind wing pads not covered by fore wing pads, but also exhibits specialized modern features, such as a short metathorax, abdominal tracheal gills, and cerci. It appears to be intermediate in structure between Paleozoic and extant mayfly nymphs.
