“…Based on this description and the provided drawings, Willmann (2007a,b) supported this phylogenetic position. Our own examination of the holotype of Bojophlebia prokopi confi rms the conclusions of Prokop et al (2010): Th e description of Kukalová-Peck includes several errors. In fact, major parts of the basal right fore and hind wings are clearly not preserved in the fossil specimen (compare Figs 51 and 52), such as wing bases, costal brace, and anal brace.…”

“…Contrary to the redescription provided by Willmann (1999) and contrary to Prokop et al (2010), the holotype of Lithoneura lameerei clearly has a small costal brace (Figs 53 and 54; also visible in fi g. 10b in Willmann 1999), so that a closer relationship of Syntonopteroidea with Ephemerida could also be supported by this putative synapomorphy, as already suggested by Rasnitsyn (2002). Prokop et al (2010) maintained that Anglolithoneura lacks a costal brace, but according to the available fi gures, the crucial region of the wing base (distinctly basal of the curved origin of CuA on CuP) is not preserved in the holotype.…”

“…Th us, we could not verify any of the crucial characters that would allow placing Bojophebia within Panephemeroptera (compare Figs 51 and 52). Prokop et al (2010) excluded Bojophlebiidae also from Syntonopteroidea, because their main apomorphies (characteristic constriction of the area between AA1+2 and AA3+4, presence of a concave longitudinal vein IN-between them, and a constriction of the area between AA3+4 and the fi rst branch of the concave AP at the same point) are not visible in the holotype of Bojophlebia , which has a broader anal area. Th erefore, Prokop et al (2010) considered Bojophlebia as a Pterygota incertae sedis.…”

Mickoleitia longimanus gen. et sp.n. is described from the Lower Cretaceous limestone of the Crato Formation in Brazil. It is attributed to a new family Mickoleitiidae and a new fossil insect order Coxoplectoptera within the palaeopterous Ephemerida, based on the presence of an elongated costal brace. Th is fossil insect exhibits a very peculiar combination of derived characters like specialized forelegs with strongly elongated, free coxae, single-clawed pretarsus, and distinctly skewed pterothorax as in dragonfl ies. On the other hand, several plesiomorphies are present that exclude this taxon from modern Ephemeroptera, namely large hind wings with widened anal area and numerous cross veins that separate the elongate costal brace from the costal margin. Fossil larvae described by Willmann as larval Cretereismatidae are herein attributed to Mickoleitiidae fam.n., based on the shared presence of broad hind wing buds with distinctly broadened anal area, wing bud venation similar to the adult holotype, and subchelate forelegs with elongate free coxae. Th ese larvae are also highly autapomorphic in the structure of their abdominal gills and laterally fl attened body with vertically oval section that is unique within Ephemerida. On the other hand they possess plesiomorphic lateral wing pads with pronounced articulation like Palaeozoic pterygote larvae, while wing pads in modern insects are always secondarily fused to the tergum. A similar fossil larva from the Jurassic of Transbaikals was earlier described as Mesogenesia petersae and classifi ed within modern mayfl ies. It is herein attributed to Mickoleitiidae fam.n. Coxoplectoptera are recognized as putative sister group of modern Ephemeroptera based on the shared presence of only 7 pairs of abdominal gills, while Permoplectoptera still have retained 9 pairs of gills. Th e phylogenetic reclassifi cation of the mayfl y stem group by Willmann is critically discussed and modifi ed. 102 A.H. Staniczek et al. / Insect Systematics & Evolution 42 (2011) 101-138

“…This FBI is the earliest occurrence in the fossil record of an FBI of a flying insect, and it provides enough morphological detail to allow possible identification of the maker. Believed to be among the first pterygote lineages, excepting Rhyniognatha (5, 6), the earliest body fossil records of basal crown-group Ephemeroptera are from the Permian, particularly Protereismatidae (6), and even more primitive stemgroup taxa (e.g., Syntonopterodea) are from the Late Carboniferous (6,7). Older evidence of winged insects exists in the form of body and wing compressions (5,6,8), as well as some indirect trace evidence of putative orthopteroid feeding (9), all of lineages other than Ephemeroptera.…”

Late Carboniferous paleoichnology reveals the oldest full-body impression of a flying insect

Insects were the first animals to evolve powered flight and did so perhaps 90 million years before the first flight among vertebrates. However, the earliest fossil record of flying insect lineages (Pterygota) is poor, with scant indirect evidence from the Devonian and a nearly complete dearth of material from the Early Carboniferous. By the Late Carboniferous a diversity of flying lineages is known, mostly from isolated wings but without true insights into the paleoethology of these taxa. Here, we report evidence of a fullbody impression of a flying insect from the Late Carboniferous Wamsutta Formation of Massachusetts, representing the oldest trace fossil of Pterygota. Through ethological and morphological analysis, the trace fossil provides evidence that its maker was a flying insect and probably was representative of a stem-group lineage of mayflies. The nature of this current full-body impression somewhat blurs distinctions between the systematics of traces and trace makers, thus adding to the debate surrounding ichnotaxonomy for traces with well-associated trace makers.Ephemeroptera | ethology | ichnology | Pennsylvanian

Deconstructing the long‐standing a priori assumption that serial homology generally involves ancestral similarity followed by anatomical divergence

It has long been assumed that serial homologues are ancestrally similarpolysomerism resulting from a "duplication" or "repetition" of forms-and then often diverge-anisomerism, for example, as they become adapted to perform different tasks as is the case with the forelimb and hind limbs of humans. However, such an assumption, with crucial implications for comparative, evolutionary, and developmental biology, and for evolutionary developmental biology, has in general not really been tested by a broad analysis of the available empirical data. Perhaps not surprisingly, more recent anatomical comparisons, as well as molecular knowledge of how, for example, serial appendicular structures are patterned along with different anteroposterior regions of the body axis of bilateral animals, and how "homologous" patterning domains do not necessarily mark "homologous" morphological domains, are putting in question this paradigm. In fact, apart from showing that many so-called "serial homologues" might not be similar at all, recent works have shown that in at least some cases some "serial" structures are indeed more similar to each other in derived taxa than in phylogenetically more ancestral ones, as pointed out by authors such as Owen. In this article, we are taking a step back to question whether such assumptions are actually correct at all, in the first place. In particular, we review other cases of so-called "serial homologues" such as insect wings, arthropod walking appendages, Dipteran thoracic bristles, and the vertebrae, ribs, teeth, myomeres, feathers, and hairs of chordate animals. We show that: (a) there are almost never cases of true ancestral similarity; (b) in evolution, such structures-for example, vertebra-and/or their subparts-for example, "transverse processes"-many times display trends toward less similarity while in many others display trends toward more similarity, that is, one cannot say that there is a clear, overall trend to anisomerism.
