I did a review on these two species.
Fleming have good upperside & underside of these two species & they support that of C&P4.
These two are distinctive in that the two cellspots (in the male) are in line with the big spot in space 2.
The spots are yellow in bononoides & whitish in bononia.
Moreover the underside colour are quite different ,ferruginous in bononoides , olive/greenish ochre in bononia.
There is no doubt with this I. bononoides.

There is also no doubt with the female I. bononia from Nakhon Si Thammarat; greenish ochre ground, brownish grey abdomen.
However, there is doubt with the male from Taman Negara.
Upperside suggest I. bononia; large cellspots , spot colour ambiguous at best.
The underside is ferruginous & the abdomen is strongly banded (compare with the female).
The male has to be I. bononoides.
