Notes
Identification about female of I.damocles and I.guttulifera is still not clear.
The difference between these species, the upper side of the forewing, spot in space 2 overlapped to lower cell spot or not.
Although Eliot,1992 treated overlapped species as guttulifera and another species as damocles, Maruyama,1991 treated them exactly the opposite.
For the time being, I follow the treatment of Maruyama.
