T his conclusion entomologa with am olecular clock study indicating that insects arose int he EarlyS ilurian about million years agowith neopteran forms present by about million years ago Gaunt and Miles, The Permothemistida [formerly the Archodonata and included in the Paleodictyoptera by Carpenter ] were a small group, characterizedb y having greatlyr educed or no metathoracicw ings, short mouthparts, and unique wing venation Figure 2.
To aid subsequent discussion of the evolutionary relationships within the Pterygota, the various orders referred to in the text are listed in Table 2. Entomologla recommended that at least the fore andh ind wings, head,a nd mouthparts should be known before a specimen is assigned to an order. The group includes two ordersProtodonata Meganisoptera UpperCarboniferous-Triassic andOdonata Triassic- Recent that are evidently closely related, some authorities even including the former in the latter order.

Carpenter published an authoritative account of the fossil Insecta in which he recognized nine orders of fossil pterygotes. Arquivos Semelhantes Aspectos gerais sobre siderurgia Aspectos gerais sobre siderurgia, aula 2.

All paleodictyopteroids Upper Carboniferous- Permian had a hypognathous head with piercing-sucking mouthparts Figure 2. Only recently have protodonate juveniles been discovered Kukalova-Peck, ; these had a mask similar to that of odonate larvae see Figures 2.
Two major schools of thought exist with regard to the origin and relationships of these evolutionary lines.

As noted earlier, the Diaphanopterodea, which may be the sister group of Paleodictyoptera, were unique among Paleoptera in that they were able to fold apostipa wings.

Phylogenetic Relationships of the Pterygota There are some 25—30 orders of living pterygote insects and about 10 containing only fossil forms, the number varying according to the authority consulted. Further, a recent studyo f 18S and 28S rDNA sequences from almost 30 species of Odonata, Ephemeroptera, and neopterans has provided strong support for the monophyly of the Paleoptera Hovmoller et al.

The traditional view, proposedb y Martynovist hat, shortlya fter the separation of ancestral Neoptera from Paleoptera, three lines of Neoptera became distinct from each other Table 2.
It has generally been assumed that the Paleoptera and Neoptera had a common ancestor [inthehypotheticalorderProtoptera Sharov, ]intheMiddleDevonian,althoughthere isn o fossil record of such an ancestor. It is now realised that this insect is a member of the order Paleodictyoptera and is not related to the modern order Hemiptera as was originally concluded. The nature of their agricolla suggests that nymphs were probably predators, some agrjcola feeding on amphibian tadpoles Kukalova-Peck, Figure 2.
For example, Wheeler et al. In contrast to theP aleoptera, which were inhabitants of open spaces, the Neoptera evolved toward a life among overgrown vegetation where thea bility to fold thew ings over thebackwhennotinusewouldbegreatlyadvantageous.

The early odonatoids differed from Ephemeroptera in features of their venation andi n having nymphst hat lacked abdominal gill plates, using instead the rectal branchial chamber for gas exchange Chapter 15, Section 4.
Though most diaphanopterodeans were plant-juice feeders, Kukalova-Peck and Brauckmann observed that some Permian species were remarkably mosquitolikea nd speculated that these may have fed on blood. Even so, none of these approaches is entirely satisfactory.
By the Upper Carboniferous period, when conditions became suitable for fossilization, almost a dozen paleopteran and neopteran orders had evolved.
