Evidence for Prothoracic Winglets in Kochopteron hoffmannorum from Hagen-Vorhalle ('basal Neoptera'; early Late Carboniferous; Germany)

摘要

A single specimen of the early Late Carboniferous (Pennsylvanian: Namurian B: late Marsdeman) Kochopteron hoffmannorum Brauckmann, 1984 (Insecta: 'basal Neoptera') from the important Konservat-Lagerstaette Hagen-Vorhalle (Germany) shows parts of the caput and a prothorax with preserved prothoracic winglets in situ. These have a relatively thin membrane, are oval in shape and are directed obliquely forward. Finer details, like for example the venation are not visible (perhaps due to poor preservation?).
