The Diaphanopterodea or Paramegasecoptera are an extinct order of moderate to large-sized Palaeozoic insects. They are first known from the Middle Carboniferous (late Serpukhovian or early Bashkirian in age), and include some of the earliest known flying insects.

Overview[edit]

Despite their very early appearance in the insect fossil record, they represent a specialised group of Palaeodictyopteroidea (Palaeozoic beaked insects), unique among representatives of that group in having evolved the ability to fold their wings over their thorax and abdomen in a manner similar to, but not homologous with, the Neopteran insects. The nymphs also had an unusual appearance, being covered in numerous hairlike filaments.[1]

Diaphanopterodea are distinguished by a number of other characteristics, and are generally considered to be a monophyletic group. About ten families are known. The group died out at the end of the Permian period, victims of the End-Permian mass-extinction, without leaving any descendants.
