1. https://www.inaturalist.org/observations/295659982
Proably Arhpala amphimuta.
The markings are as for the amphimuta group and looks to be A. amphimuta itself.



2. https://www.inaturalist.org/observations/295659956
Udara selma.
Salient features.
1. N submarginal spots/ lunules.
2. UnH postdiscal spot 7 darker than the other postdiscal spots.
UnH tornal area with two spots ( in space 1b).
https://www.gbif.org/occurrence/2847200311
https://www.gbif.org/occurrence/2847200313

Very similar.
Udara camenae, sharing features 1 and 2, but UnH tornus with three spots ( 2 in space 1b, and 1 in space 1a.).
https://www.gbif.org/occurrence/2847200814
https://www.gbif.org/occurrence/2847201838



3. https://www.inaturalist.org/observations/295659950
Koruthaialos sindu.
Outer border of orange band with a notch near mid-margin.
https://yutaka.it-n.jp/hes/91530001.html



4. https://www.inaturalist.org/observations/295659924
Probably Nacaduba berenice.
The markings are that of this species.
The marginal and submarginal spots are outlined with white striae.
Only Prosotas aluta and dubiosa have these features.



4A. https://www.inaturalist.org/observations/295659947
Idmon distanti.
Plain brown . The palpus with a long 3rd segment(visible in pic 1 and 2).
The white spot is an artifact since it is only present in pic1.
https://www.gbif.org/occurrence/2847177094
Note long palpus 3rd segment.

5.https://www.inaturalist.org/observations/294876206
https://inaturalist-open-data.s3.ama...9/original.jpg
Likely Hasora khoda.

The white band appear similar to H. vitta due to some distortion and blurring.
The truer shape is as in Pic 2.

Three species are very similar.

1. Hasora vitta.
Male and female always with a subapical spot 6; ;Female also have FW spots 2 and 3.
Band typically broaden in the upper half, fuzzy on the outer margin
UnH basal half with slatey blue-green sheen.
Male & female.

https://www.inaturalist.org/observations/220482183
https://www.inaturalist.org/observations/284442122


2. Hasora chromus.
Male without subapical spot 6; female usually with one.
HW band uniformly narrow ,fuzzy on both sides .
HW basal half dully purple-washed.
Male & female.
https://www.gbif.org/occurrence/2847176193
https://www.gbif.org/occurrence/2456362017
https://www.inaturalist.org/observations/293316978
https://www.inaturalist.org/observations/199776462


3. Hasora khoda.
Male without subapical spot 6; female with.
HW band fuzzy on outer margin, typically broader than in chromus.
HW basal half brown.
Male (Chantaburi)
https://yutaka.it-n.jp/hes/90260010.html
Female.
https://www.gbif.org/occurrence/2456361921

Note this can not be H. vitta because both sexes of H. vitta have a subapical spot.



6.https://www.inaturalist.org/observations/294876203
Neptis harita.

The HW submarginal spots form a chain-link like arrangement.
https://wingscales.com/Nymphalidae/Neptis-harita-harita




7.https://www.inaturalist.org/observations/294845054
It look like it could be the female Caltoris sirius but could easily also be something else.
I have no idea if C. sirius is found on Penang Hill.
Male.
https://www.gbif.org/occurrence/2456362046
Female.
https://www.gbif.org/occurrence/2847176740

8.https://www.inaturalist.org/observations/294071089
This does look like it is Celastrina.
There is only one species here.
C. lavendularis.

9. https://www.inaturalist.org/observations/294071067
10. https://www.inaturalist.org/observations/294071065
Both should be Pithauria stramineipennis.
It have this strange white interneural spot in space 6.

https://www.ifoundbutterflies.org/node/205292


11. https://www.inaturalist.org/observations/294071064
Hasora leucospila.
This has a large tornal white spot.
The female was thought to be a diiferent specoes until breeding established its identity.
https://yutaka.it-n.jp/hes/90280001.html


12. https://www.inaturalist.org/observations/294845047
Potanthus lydia.
The abdominal enfd is heavily black-banded.
FW spot 4 & 5 tend to have their inner margins converging in a 'V'; spots 2 and 3 wide.
Male, fwmale.

https://www.gbif.org/occurrence/2456362409

13.https://www.inaturalist.org/observations/293757459
Too blur. Probably Tajuria spp.

14. https://www.inaturalist.org/observations/293701407
Too blur.
Could be alea subgroup.


15.https://www.inaturalist.org/observations/293701407
16. https://www.inaturalist.org/observations/293701388
Way too blur. Its anybody's guess.

Added. Different perspective looks .

BTW there are only T iapis and godartii on Penang Hill .
They are both common.
