genera is problematical. I have placed it close to Baleja Melichar because of 
the concave clypellus, shared by both, because of the similarity of the second 
valvulae of the ovipositor of P. gratiosa (Blanchard) to the same structure in 
Baleja, and because the common form of the aedeagus in Parathona is near that 
of B. discordans, n. sp.. Externally, the species of Parathona are similar to 
Scoposcartula, new genus. Parathona species are more robust than Baleja and 
with the head less produced. Also, the apical membrane of the forewing is 
more extensive in Parathona. It seems to be related also to Sailerana, new genus, 
in the discussion of which distinguishing characters are noted.
