Thank you so much Dr. Seow for all your review and detailed discussion.
I got quite confused on

https://www.butterflycircle.com/atta...2&d=1737380401

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

No. 18 Revision

Attachment 28739 Attachment 28740

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.

Amblychia nimia.
Prout's description.
https://archive.org/details/novitate...p?view=theater
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.
https://www.gbif.org/occurrence/gall...n_key=11560614
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'.

1. Differ from hymenaria in being paler & browner.
2. Abdomen yellow beneath.
3. Und white ,with black discal spot & submarginal patches to each wing.
4 Ssp megaspilata large, like hymenaria ,underside with complete submarginal band.

https://www.mothsofindia.org/sites/m...63c10d6b-1.jpg

If you have the specimen you may want to check the abdomen if it is ssp megaspilata of A. pardicelata.

TL Seow: Cheers.
PS.
This is likely to be an example of ssp megaspilata as it has a complete submarginal band.
(Correction: This is a misID of a Chorodna sp.? creataria.)
https://www.gbif.org/occurrence/4917413768
In NE India there will be all range of intermediates between ssp pardicelata and ssp megaspilata.

PS2.
Hampson's description of ssp megaspilata seem in error.

Here is the original author ,Warren's description .
Megaspilata means large spotted, and Warren was referring to the large UnH submarginal spots.
There should not be a complete band there.
page 430.

Thank you for this detailed review. All the ID pointers perhaps suggest it to be A. hymenaria. The underside matches hymenaria, but the white patch beyond the discal spot is rather weak.

Here is the close view of the abdomen following Hampson's description of A. pardicelata
Abdomen does not seem to be yellow beneath

18 Best left as Amblychia hymenaria.
I still think there is a hybrid element.


42. https://www.butterflycircle.com/atta...3&d=1738525066

This has also been identified as Nosophora semtritalis but I think it is a different species.
FW postmedial is like a wine-glass, with the lower spot much reduced.

Typical N. semitritalis can be seen from HongKong & Taiwan.
The FW postmedial is like a fig of eight ,the two spots large.

No literature.


43. https://www.butterflycircle.com/atta...4&d=1738525183
This does look correct as C. olivescens.
In particular, the ground is darker & the HW discal spot is large.

There seem a whole range of intermediates between typical C. sublsvsria & C. olivescens.

[Psyche]

44.https://www.butterflycircle.com/atta...7&d=1738525419

Likely to be Teldenia specca.

There are a lot of confusion between the three species, T. vestigiata, specca & alba.
I will leave T. alba alone, its appearance is also confusingly similar to T. specca which seem to occur in Sri Lanka as well.

T. vestgiata.
FW submarginal lunules more regular & more or less parallel to the postmedial spots.
Lower end of postmedial spots le3ss convex.

T. specca widespread from India to PNG.
FW submarginal lunules highly irregular, & not parallel to the postmedial.
Lower part of postmedial less convex.

45. https://www.butterflycircle.com/atta...8&d=1738525674
Bradina admixtalis looks the correct match.
There is very little literature on Bradina.


46.https://www.butterflycircle.com/atta...9&d=1738525970

Hypena indicatalis is very close & very likely the correct match.

TL Seow: Cheers.
PS.
Now more often known as Dichromia indicatalis.

[Saffron]

Thank you Seow sir for such detailed discussion. Was busy in some office work these days. Hardly got time to follow the discussion. But back to my field work again.
The keys of the genus Teldenia are very helpful.
The remarks on the Nosophora species is very interesting. I also do feel there may be another species that is perhaps narrowed down as Nosophora semtritalis with the Fw lower spots typically reduced.

Cheers

In going through the Nosophora ,the forms with the lower postmedial spot large occur in the east ie, Hk, Taiwan ,Korea, & Japan.

The forms with the lower postmedial spot reduced is mainly in NE India.

Since the author below is pretty accurate with his IDs, N. semitritalis should be correct.
