Article: Nymphs of Palaeodictyoptera (Insecta) from the Westphalian of England

The remains of three nymphal Palaeodictyoptera from the English Coal Measures (Upper Carboniferous) are described: Rochdaliaparkeri Woodward 1913; Idoptilus onisciformis n. gen., n. sp.; and a wing pad and prothoracic fragment situated in the pelvis of the holotype of the amphibian Eugyrinus wildi. The two named nymphs are onisciform, with prothoracic and true abdominal paranotal lobes, and posterolaterally directed wing pads; they show no aquatic adaptions; and the relief of their pronota is complex, and comparable with that of the meso- and metanota. The fossils are not assigned to families; but Idoptilus is compared with Eugereo-nidae and Breyeriidae, and Rochdalia and the third nymph with Dictyoneuridae. The prothoracic paranota and wing pads may have been capable of movement.
