Abstract The Paleozoic to Mesozoic grade ‘Protozygoptera’ is revised. It appears to be composed of two main lineages, namely the superfamily Permagrionoidea, and the Archizygoptera. The latter taxon forms a monophyletic group together with Panodonata ( = crown-Odonata plus their closest stem-relatives). Therefore, the ‘Protozygoptera’ as previously understood is paraphyletic. Diagnostic characters of the ‘Protozygoptera’, Permagrionoidea, and Archizygoptera are re-evaluated. The Permolestidae… 

New Middle Permian insects from Salagou Formation of the Lodève Basin in southern France (Insecta: Pterygota)

Entomofauna from the Salagou Formation demonstrate highly diverse insect communities with some taxa linked to early and late Permian ones known from assemblages in Euramerica and Russia, such as Obora (Czech Republic), Wellington Formation (Kansas and Oklahoma, USA), and Tshekarda (Ural, Russia).

A new species of the ʻprotozygopteranʼ damselfly (Odonata: Permagrionidae) from the Lower-Middle Permian of Russia

The small Paleozoic protozygopteran family Permagrionidae comprises 11 described species in 5 genera from the Lower Permian Chekarda and Solikamsk localities in Russia (Zalessky, 1948; Nel et al.,

New Damselflies of the Family Kennedyidae (Odonata: Protozygoptera) from the Upper Permian of the Vologda Region

A new species of damselfly of the family Kennedyidae: Kennedya suchonensis sp. nov. is described from the Upper Permian (Severodvinian) deposits of the Isady locality (Vologda Region, Velikoustyugsky

A new triadotypid insect from the Late Triassic of South Africa

Extant odonates (damsel- and dragonflies) represent a small subset of the historical biodiversity of this group. Among their successive stem-groups, the Triadotypomorpha are poorly documented. Herein

New insects from the earliest Permian of Carrizo Arroyo (New Mexico, USA) bridging the gap between the Carboniferous and Permian entomofaunas

New insects are described from the early Asselian of the Bursum Formation in Carrizo Arroyo, NM, USA, showing close relationship between late Pennsylvanian and early Permian entomofaunas.

The First Damselflies of the Family Kennedyidae (Odonata: Protozygoptera) from the Permian–Triassic Boundary Deposits of the Kuznetsk Basin, Russia

Two new fossil damselfly species of the family Kennedyidae are described from the presumed Lower Triassic beds of the Permian-Triassic locality Babiy Kamen’.

The wing venation of the Protomyrmeleontidae (Insecta: Odonatoptera) reconsidered thanks to a new specimen from Molteno (Triassic; South Africa)

A new Triassic specimen from the Molteno Formation (Karoo Basin, South Africa), Moltenagrion koningskroonensis gen. et sp.



A revision of the Upper Jurassic-Lower Cretaceous dragonfly family Tarsophlebiidae, with a discussion on the phylogenetic positions of the Tarsophlebiidae and Sieblosiidae (Insecta, Odonatoptera, Panodonata)

The Upper Jurassic-Lower Cretaceous dragonfly family Tarsophlebiidae is revised, including important new information on its head, legs, wings, anal appendages and male secondary genital apparatus, and the Oligo-Miocene family Sieblosiidae seems to be more closely related to the Epiproctophora than to the Zygoptera.

How Time Flies for Flies: Diverse Diptera from the Triassic of Virginia and Early Radiation of the Order

Flies did not reach modern levels of ecological abundance until the mid-Jurassic, apparently due to diversification within most infraorders by that time, and is described from the Late Carnian of Virginia, USA.

New morphological data from the Jurassic of Inner Mongolia confirms the damselfly aspect of Protomyrmeleontidae (Insecta: Odonatoptera)

The nearly complete absence of the meso-metathoracic interpleural suture, newly discovered in the Protomyr- meleontidae, can be considered as a synapomorphy of the clade Protozygoptera + Odonata.

Triassic Diptera and initial radiation of the order

The origin of Diptera from Permian Mecoptera similar to Robinjohniidae is suggested; it's hypothesized that the dipteran wing structure was formed mainly due to transfer of mecopteran hindwing characters onto the forewing.

New results concerning the morphology of the most ancient dragonflies (Insecta: Odonatoptera) from the Namurian of Hagen-Vorhalle (Germany)

A phylogenetic analysis suggests that the Palaeozoic giant Meganisoptera and “higher” odonatoids together form a monophyletic group which is here named Euodonatoptera, and Erasipteroides and the other ‘Erasipteridae’ are shown to be more closely related to Euodictyoptera than to Eugeropteridae.

Molecules, morphology and fossils: a comprehensive approach to odonate phylogeny and the evolution of the odonate wing

Fossil taxa did not seem to provide signals crucial to recovering a robust phylogeny, but were critical to understanding the evolution of key morphological features associated with flight.

A molecular phylogeny of the Odonata (Insecta)

Several recent taxonomic changes at the genus level, based on morphology, were confirmed, but other morphology‐based taxonomies have misclassified taxa considered currently as Megapodagrionidae, Platycnemididae and Amphipterygidae and have underestimated the number of family‐level clades.
