Fig. 5 in Deep time extinction of largest insular ant predators and the first fossil Neoponera (Formicidae: Ponerinae) from Miocene age Dominican amber
Fig. 5 Size distribution of extant and extinct ant predators on Hispaniola. Principal component 1 derived from PCA of three morphometric traits across taxa. Fossil ants (yellow) exhibit larger body sizes than extant taxa (gray) on average and among extremes. Note: plot includes alate (queen) specimens, including the largest known fossil ant species, an undescribed Fulakora queen

Fig. 1 Photomicrographs of Neoponera vejestoria sp. nov. (Holotype, MNHNSD FOS 18.01). A Head in frontal view. B Body in dorsal view. C Body in lateral view. Scale bars: A 1 mm; B, C 2 mm
Fig. 3 in Deep time extinction of largest insular ant predators and the first fossil Neoponera (Formicidae: Ponerinae) from Miocene age Dominican amber
Fig. 3 Principal component analysis morphospace of Neoponera ants according to species group. The sampling comprised 47 species represented by 12 linear morphological measurements. PC1 corresponds with the overall body size. Neoponera vejestoria is denoted with the blue star. The first five principal components of the Neoponera dataset make up 98% of the total variance. Principal component 1 comprises 84.14% of the variance; principal component 2 reflects the overall body shape, mainly in the pronotal width and petiolar dimensions (see Additional file 1: Fig. S4), comprising 5.61% of the variance

Data from: A winged relative of ice crawlers in amber bridges the cryptic extant Xenonomia and a rich fossil record
<p>Until the advent of phylogenomics, the atypical morphology of extant representatives of the insect orders <em>Grylloblattodea</em> (ice crawlers) and <em>Mantophasmatodea </em>(gladiators) had confounding effects on efforts to resolve their placement within Polyneoptera. This recent research has unequivocally shown that these species‐poor groups are closely related and form the clade Xenonomia. Nonetheless, divergence dates of these groups remain poorly constrained, and their evolutionary history debated, as the few well‐identified fossils, characterized by a suite of morphological features similar to that of extant forms, are comparatively young. Notably, the extant forms of both groups are wingless, whereas most of the pre‐Cretaceous insect fossil record is composed of winged insects, which represents a major shortcoming of the taxonomy. Here, we present new specimens embedded in Early Cretaceous amber from Myanmar and belonging to the recently described species <em>Aristovia daniili</em>. The abundant material and pristine preservation allowed a detailed documentation of the morphology of the species, including critical head features. Combined with a morphological data set encompassing all Polyneoptera, these new data unequivocally demonstrate that <em>A. daniili</em> is a winged stem <em>Grylloblattodea</em>. This discovery demonstrates that winglessness was acquired independently in <em>Grylloblattodea </em>and <em>Mantophasmatodea</em>. Concurrently, wing apomorphic traits shared by the new fossil and earlier fossils demonstrate that a large subset of the former "Protorthoptera" assemblage, representing a third of all known insect species in some Permian localities, are genuine representatives of Xenonomia. Data from the fossil record depict a distinctive evolutionary trajectory, with the group being both highly diverse and abundant during the Permian but experiencing a severe decline from the Triassic onwards.</p>
