terminal fork, whereas in the spilapterids CUA has several long 
branches. This difference serves to justify the separation of Eublep- 
tus into its own family, but does not have any significance at the 
ordinal level. The body structure of Eubleptus turns out to be very 
similar to that of the spilapterids. The pronotal lobes are small in 
both, the beaks are relatively small and of similar shape in both, the 
legs (so far as they are known) are short in both, and the ovipositors 
are similarly formed. Eubleptus danielsi is the smallest known spe- 
cies in the Palaeodictyoptera, but it is not much smaller than the 
Permian Dunbaria faseiipennis of the family Spilapteridae.
