A Total-Evidence Approach to Dating with Fossils, Applied to the Early Radiation of the Hymenoptera
TLDR
The results suggest that the crown group dates back to the Carboniferous, ∼309 Ma (95% interval: 291--347 Ma), and diversified into major extant lineages much earlier than previously thought, well before the Triassic.
Phylogenetic relationships among superfamilies of Hymenoptera
TLDR
The first comprehensive analysis of higher‐level phylogeny of the order Hymenoptera is presented and all currently recognized superfamilies are supported as monophyletic.
Beyond the wasp‐waist: structural diversity and phylogenetic significance of the mesosoma in apocritan wasps (Insecta: Hymenoptera)
TLDR
The results of the present analyses indicate that a reclassification, especially of Proctotrupoidea, is required, but this should be carried out after thorough analyses of more comprehensive combined data sets.
Phylogeny and classification of the extant basal lineages of the Hymenoptera (Insecta)
TLDR
The phylogeny of the basal hymenopteran lineages, including representatives of all «symphytan» families, is analysed and it is proposed to elevate the Anaxyelidae and the Xiphydriida both to superfamily status.
The Hymenopteran Tree of Life: Evidence from Protein-Coding Genes and Objectively Aligned Ribosomal Data
TLDR
The 18S and 28S data are reanalyzed using an objective and a semi-objective alignment approach, based on MAFFT and BAli-Phy, respectively, to provide independent confirmation of several earlier results, and confirm that Aculeata are nested within a paraphyletic Evaniomorpha, but cast doubt on the monophyly of Evanioidea.
The ovipositor apparatus of basal Hymenoptera (Insecta): phylogenetic implications and functional morphology
TLDR
The skeleto‐musculature of the ovipositor apparatus and the external sculpture of the 1st and 2nd valvulae was studied in representatives from all ‘symphytan’ families and the configuration of the musculature did not display much variation among the taxa examined.
The Greenland entomofauna : an identification manual of insects, spiders and their allies
In 'The Greenland Entomofauna' an international team of 64 taxonomic specialists provide a richly illustrated guide to the identification of the approximately 1200 species of hexapods/insects,…
The preoral cavity of lower Hymenoptera (Insecta): comparative morphology and phylogenetic significance
The skeletal and muscular morphology of the preoral cavity, including the labrum, hypopharynx and labium, was examined in the imago in representatives of all the ‘symphytan’ families as well as the…
Morphological and molecular evidence converge upon a robust phylogeny of the megadiverse Holometabola
TLDR
It is argued that even in the “age of phylogenomics”, comparative morphology will still play a vital role and is essential for reconstructing major evolutionary transformations at the phenotypic level, for testing evolutionary scenarios, and for placing fossil taxa.
A molecular phylogeny of Dorylus army ants provides evidence for multiple evolutionary transitions in foraging niche
TLDR
The evolutionary transitions in foraging niche were more complex than previously thought, but the comparative analysis of worker morphology lends strong support to the contention that particular foraging niches have selected for very specific worker morphologies.
