Discovery of new dragonflies from Oligocene and Miocene deposits the Most Basin České Středohoří Complex volcanic area in northern Bohemia Saxony (Germany) is reported. Aeshna zlatkokvaceki sp. nov. first described dragonfly early salmon-pink baked clays Želénky near Duchcov. Its fore wing venation pattern seems to be closely related that turoliana Riou Nel, 1995, known late La Montagne d'Andance Ardèche, France, solida Scudder, 1890, Eocene Florissant Colorado, USA. A occurrence a...
Pecharová, M., Ren, D. & Prokop, J., 29.01.2015. A new palaeodictyopteroid (Megasecoptera: Brodiopteridae) from the Early Pennsylvanian of northern China reveals unique morphological traits and intra-specific variability. Alcheringa 39, XXX–XXX. ISSN 0311-5518Evaluation abundant insect fossils (Namurian) Tupo Formation (Xiaheyan locality, Ningxia Hui Autonomous Region) enabled description a megasecopteran, i.e., Brodioptera sinensis sp. nov. emendation Brodiopteridae. is defined principally...
Abstract Megasecoptera are insects with haustellate mouthparts and petiolate wings closely related to Palaeodictyoptera one of the few insect groups that didn’t survive Permian-Triassic mass extinction. Recent discovery Brodioptera sinensis in early Pennsylvanian deposits at Xiaheyan northern China has increased our knowledge its external morphology using conventional optical stereomicroscopy. Environmental scanning electron microscopy (ESEM) structures, such as antennae, mouthparts, wing...
The largest insects to have ever lived were the giant meganeurids of Late Palaeozoic, ancient stem relatives our modern dragonflies. With wingspans up 71 cm, these iconic been subject varied documentaries on Palaeozoic life, depicting them as patrolling for prey through coal swamp forests amid lycopsids, and cordaites. Such reconstructions are speculative few definitive details dragonfly biology known. Most specimens dragonflies known from wings or isolated elements, but Meganeurites...
Li, Y., Ren D., Pecharová, M. & Prokop, J., 2013. A new palaeodictyopterid (Insecta: Palaeodictyoptera: Spilapteridae) from the Upper Carboniferous of China supports a close relationship between insect faunas Quilianshian (northern China) and Laurussia. Alcheringa 37, 1–9. ISSN 0311-5518.A Sinodunbaria jarmilae gen. et sp. nov. (Spilapteridae) is described illustrated (Namurian) Tupo Formation northern (Ningxia Hui Autonomous Region). The taxon, based on fore- hindwing venation pattern,...
The systematic positions of the extinct insect orders Hypoperlida, Miomoptera and Permopsocida were enigmatic unstable for nearly a century. recent studies based on new material, especially from Cenomanian Burmese amber, shed light evolutionary history Acercaria resolving as stem group Condylognatha. However, knowledge remaining two differs significantly. In this study, we describe specimens evaluate morphology various structures with emphasis mouthparts wing venation. Our results are...
New archaeorthopterans Contracladus impar gen. nov. et sp. (uncertain assignement), Paraspiculum brauckmannii (Caloneurodea) and Piesbergopterum punctatum (Cnemidolestodea) are described from the Moscovian of Piesberg quarry near Osnabrück (Lower Saxony, Germany). All new taxa display unique patterns their forewing venations. The mosaic characters found in C. with a particular lack free vein CuA demonstrates limits current systematics for Archaeorthoptera. evidence supposedly disruptive...
Abstract A new palaeodictyopterid nymph Bizarrea obscura gen.n. et sp.n. ( S pilapteridae) and a adult specimen of Homaloneura cf. dabasinskasi C arpenter are described from the P ennsylvanian M oscovian) ironstone nodules azon reek (IL, U.S.A. ). Both taxa share enlarged prothoracic lobes (interpreted by some as winglets), heteronomous meso‐ metathoracic wing pads or wings, slender abdomen with pointed laterotergites, unique division abdominal segments two transverse sulci. An alternative...
The Late Palaeozoic insect superorder Palaeodictyopterida exhibits a remarkable disparity of larval ecomorphotypes, enabling these animals to occupy diverse ecological niches. widely accepted hypothesis presumed that their immature stages only occupied terrestrial habitats, although authors more than century ago hypothesized they had specializations for amphibious or even aquatic life histories. Here, we show different species semiaquatic in larvae and the supposed retention abdominal...

ABSTRACT New palaeodictyopterans, Vernooijia sassoonae gen. et sp. nov. (Breyeriidae) and Mazonopterum cooperi (Homoiopteridae) are described from the Middle Pennsylvanian (Westphalian D/Late Asturian) of Writhlington, near Radstock (UK). Based on re-examination venation in Breyeria harlemensis , we propose transfer this species to genus as V. (Brauckmann & Gröning, 1996) comb. We report first record Homaloneura (Spilapteridae) Langsettian Duckmantian Coseley, Staffordshire....
At the famous Moscovian locality of Piesberg quarry near Osnabrück (Lower Saxony, Germany) there is rich abundance Palaeodictyopterida comprising not only adults but also larval stages and their exuviae. The representatives three palaeodictyopterid orders, eight families 13 species were previously identified from this locality. In study, we describe a new megascopteran Piesbergptera niesseae gen. nov. et sp. (Piesbergpteridae fam. nov.) with some venation traits shared Foririidae...
Archaeorthoptera is a high rank insect taxon comprising Orthoptera as well the extinct orders Titanoptera and Caloneurodea, several other late Paleozoic groups formerly assigned to polyphyletic Protorthoptera.Synapomorphies defining some fossil subordinate taxa are exclusively based on wing venation.This study presents detailed description of two new archaeorthopteran genera three species from Pennsylvanian Upper Silesian Coal Basin in Poland.These provide insights into venation disparity...
A new species of fossil hoverfly (Syrphidae: Eristalinae), i.e., Blera miocenica sp. nov. is described from the Early Miocene (Burdigalian) Bílina mine in Most Basin, Czech Republic. The description based on a well preserved compressed and it represents first known record genus Billberg, 1820 so far. B. diagnosis wing venation other body characters like coloration pattern abdomen. resemblance to extant briefly discussed. previously suggested palaeoenvironmental conditions at type locality...
