Notes

I think the figured specimen belongs this species.
Inoué & Kawazoé,1967 described this species as subspecies of I.dawna. Then Eliot,1973 treated it as subspecies of umbrosa.
However harpe of the male genitalia is quite different from umbrosa and dawna. Besides, There are both I. umbrosa contracta and I. minuscla occurs in S.Vietnam.
I consider this taxon should be a distinct species.
