Dragonflies and damselflies are among the earliest flying insects with extant representatives. However, unravelling details of their long evolutionary history, such as egg laying (oviposition) strategies, is impeded by unresolved phylogenetic relationships particularly in damselflies. Here we present a transcriptome-based phylogenetic reconstructio...
A stem relative of dragon- and damselflies, Brunellopteron norradi Béthoux, Deregnaucourt and Norrad gen. et sp. nov., is documented based on a specimen found at Robertson Point (Grand Lake, New Brunswick, Canada; Sunbury Creek Formation; early Moscovian, Pennsylvanian) and preserving the basal half of a hindwing. A comparative analysis of the evol...
Probably the most common rock-imprint fossil-insect remain is an incomplete isolated wing. This pitfall has been traditionally addressed by manually reconstructing missing parts, which is not ideal to comprehend long-term evolutionary trends in the group, in particular for morphological diversity (i.e., disparity) approaches. Herein we describe a n...
Five major crises have affected biodiversity and human activities are leading to a sixth one. Disparity, aiming at quantifying morphological diversity, might be a relevant approach to compare these crises. Disparity has, however, rarely been applied in conservation biology. Here we investigated the impact on Odonata wingdisparity (1) of land cover...
Two new, subcomplete forewings belonging to the ‘triassolestid assemblage’, a group of Triassic stem-relatives of dragon- and damselflies (Odonata), are described. One, recovered from Australia (Aranbanga Volcanic Group), belongs to Mesophlebia antinodalis Tillyard, 1916, previously documented on the basis of two very incomplete wings. The other, r...
Wing venation homologies of the Protomyrmeleontidae, a widespread group of damselfly-like stem-Odonata during the Triassic, are debated. The two main interpretations essentially disagree on the identification of RP branches. Indeed, Protomyrmeleontidae display a very complex wing venation necessarily involving, in a way or another, fusions of the c...
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 we describe a new species Reisia rieki from the Molteno Formation (South Africa, Upper Triassic) belonging to this taxon. The comparatively large samp...
