Tillyard, in his Panorpoid Complex, concluded from a study 
of recent and fossil Neuroptera that the ancestral and 
primitive forms of the order possessed only a few, widely- 
spaced cross-veins, and nothing has subsequently been found 
to refute his view. This small number of cross-veins is the 
only characteristic of Nesonymphes which is not found in 
Nymphes or closely related genera now existing in the 
tropics.
