Abstract

When the Zeugloptera are compared with advanced Lepidoptera three major changes in the hind wing base are noticed:

1) The apparent loss of the prescutal arm which is fused to the second basalare in Ditrysia.

2) The separation of the prescutal apodeme from the prescutum by membrane so that the third tergopleural muscle appears to insert on the mesopostnotum.

3) The reduction of the median plates and the development of cubital plates.
