Thank you so much Dr. Seow for all your review and detailed discussion.
I got quite confused on
18. https://www.butterflycircle.com/atta...1&d=1737379694

Here are the specimen images of this above attached individual collected.

No. 18 Revision

Does this match Amblychia pardicelata?

After going through some web searches and taxonomic review of the old literature, this also has resemblance with A. hymenaria.

Kindly help me out in this case.

Literature suggest the underside of A. pardicelata to be whitish with a large black spot at the end of the discal area.

This is perhaps a male individual.

What a terrible confusing mess.
You are right.
It should be Amblychia hymenaria.

In SE Asia including neigbouring Thailand, A. hymenaria have a distinct oblique white FW band.

Strange to have banded form in S, India.(Correction : female have stronger band.)

Amblychia nimia.
Prout's description.

Prout indicate Hampson's description of A. hymenaria should be A. procellosa, but 'procellosa' is now a junior synonym of hymenaria.
Correction: Prout was referring to Warren's description of hymenaria which should be procellosa.
Note UnF heavy with confluent spots.

TL Seow: Cheers.
PS.
Likely an intermediate cross, possibly with nimia.
The underside is as in hymenaria, but the white patch beyond the discal spot is rather weak
PS2.
All forms of A. hymenaria typically have some form of an oblique band on the FW.
From India & Sri Lanka.

Guenee's description of A. hymenaria is in French.
His description of the underside is as follow.
White underside, whipped with black, with a wide black border indented at the terminal edge by white spots that are missing between 1 and 1'.
