1.https://www.inaturalist.org/observations/335296425

Neptis clinia.

The arrangement of the spots are as for Neptis clinia.
The ground colour is very variable ,being brownish in seasonal climate.
The HW discal band reaches the costa but this is hidden at rest.
HW discal band is uniform in width.
https://www.gbif.org/occurrence/3772620297
https://www.gbif.org/occurrence/2847206098
https://www.gbif.org/occurrence/2847206091

Very similar is Neptis clinioides.
This is darker and prefer higher elevations.
The HW discal band is narrow at the inner margin(dorsum) and expands towards the costa.

https://www.gbif.org/occurrence/2847206119

[Psyche]

2.https://www.inaturalist.org/observations/335119514

Taractrocera archias.
The UnH with a large spot 6 joining the main band is that of T. archias.
https://www.butterflycircle.com/checklist/mugshots/Taractrocera%20archias%20quinta/Taractrocera%20archias%20quinta%20-%20Khew.jpg

The other two similar species do not have a large spot 6.
T. luzonensis.
https://yutaka.it-n.jp/npict15c/92600010_n001.jpg
T. nigrolimbata.

3. https://www.inaturalist.org/observations/335296444

Potanthus speciee3s.
Too dark.



4. https://www.inaturalist.org/observations/335238252
Likely to be Halpe ormenes.

The Halpe species can be very difficult to ID.

Halpe zema.
UnH band usually yellowish, lower end in sace 1b always strongly angled out.
Outer margin of band strongly irregular with deep serration.
https://yutaka.it-n.jp/hes/91250010.html
https://wingscales.com/Hesperiidae/Halpe-zema-zamba
https://www.inaturalist.org/observations/302562381
https://www.inaturalist.org/observations/313815673



Halpe ormenes.
UnH band typically white or off white, the lower end in space 1b angled out as in H. zema.
Its outer margin is less irregular ,fuzzy or with shallower incisoins/serration than in zema.
https://yutaka.it-n.jp/hes/91260010.html
Note male on the left have deeper serrations, closer to zema.
https://www.butterflycircle.com/checklist/mugshots/Halpe%20ormenes%20vilasina/Dark%20Banded%20Ace%20-%20Mark.jpg
https://www.inaturalist.org/observations/286297998
https://www.inaturalist.org/observations/308652775
https://www.inaturalist.org/observations/213989409



Halpe elana.
This have narrower UnH band which appears sinuous.
https://yutaka.it-n.jp/hes/91280001.html


Halpe zinda zodia.
This is a rarity occurring mainly in the northern half especially Kedawi.
The UnH band is usually white, the lower inner margin is nearly straight.
Since space 1b is more often mostly hidden this can be hard to judge.
https://yutaka.it-n.jp/hes/91253010.html
This observation is almost a certainty to be Halpe zinda as the lower end of the HW band is almost straight.
https://www.inaturalist.org/observations/270402867
This 2nd shot could also be a possibility.
https://www.inaturalist.org/observations/271880252
Added. 3rd possibility. Note lower inner margin of band straight.
https://www.inaturalist.org/observations/283191521

[Psyche]

5.https://www.inaturalist.org/observations/335302110
Curetis tagalica or saronis.
Too dark.
C. saronis have reddish to red brown banded legs.
C. tagalica have black/grey banded legs.



6. https://www.inaturalist.org/observations/335169694
UFO.



7. https://www.inaturalist.org/observations/335155577
Male Jamides pura.
At first sight the rounded FW suggest J. celeno but this is due a strong perspective distortion.
By counting the white striae from the inside outwards
1 On the FW the 7th white stria is the margin with the black cilia, followed by a blue-grey zone edged in black. The blue grey zone is the upperside of the opposite FW.
2. On the HW the 9th white stria is the margin with black cilia, followed by the blue-grey upperside of the pposite HW.
You can compare the underside of these specimens.
https://www.gbif.org/occurrence/5897758862
https://www.gbif.org/occurrence/2847200489
https://www.gbif.org/occurrence/2847200486

The UpF of continental J. pura pura male is unmarked.
There are no examples with black dotted FW margin.
There is a tendency to have the silvery sidebars on the HW black tornal spot long.

[Psyche]

8. https://www.inaturalist.org/observations/335169668
Chersonesia rahria.
This is the only species in which the FW apex is dark,marked by a curved fascia.


9. https://www.inaturalist.org/observations/335296446
This unmarked species is very likely to be Pelopidas flavus of which very little is known.


10. https://www.inaturalist.org/observations/335302119
Male Jamides pura.
The 1st pic. shows the opposite FW apex, pale blue with only a black margin.

[Psyche]

11. https://www.inaturalist.org/observations/334899806

Likely Salanoemia fuscicornis
Antennal club whitened.
Head marked by a black line.
FW with subapical spots; HW with darkish spots.
https://wingscales.com/Hesperiidae/Salanoemia-fuscicornis



12. https://www.inaturalist.org/observations/334899824
Euploea camaralzeman.

https://yutaka.it-n.jp/dan/30560010.html
https://yutaka.it-n.jp/dan/30740010.html

[Psyche]

13. https://www.inaturalist.org/observations/334722168
Pyroneura flavia.

Three species have a similarly marked FW.
A line through FW spots 6 & 7 is directed to the dorsum, ie lower margin.
HW with vein 8 scaled orange on both sides.

In both P. helena and natuna there is an opalescent white streak in space 5 just below spots 6 & 7.
P. helena.
https://thaibutterflies.com/Butterflies/pyroneura-helena/
P. natuna.
https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEipQPxnUj2hJmhlosVzAyzxon_-LyCVNVd7diTUsItjNEEzUwoZdPE-xKkEDQCrysmXHmeyCRO62VhTCcFVdreHtp_2O2ryBDebLDeEO1 hk4_Mz8k8_BemEQHqG3b-Fyy0UM1BuxhJbGb0/s1600/DSC_0104.JPG

P. flavia .
Opalescent streak in FW space 5 is absent in the male and weak in the female.
https://thaibutterflies.com/Butterflies/pyroneura-flavia/

P. niasana.
https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgmJQjOw-YJqB8EkAIGlS0JySIxRKY8_37IA9G9EklamjNLQAAM0yGCKBYp 4Y7UNYzMPBOOiEW7F7RlQU3Yyv46uOiasu_2_G0qpbZhTFpj1E XiXcDHothCfcIrlxKpsvdubIhk7Zh2EQs/s1600/DSC_1737.JPG

14.https://www.inaturalist.org/observations/334721944
Idmon distanti.

This is an unmarked species in which the 3rd segment of the palpi are long and upright. This is only visible at certain angles.
In the pic. the large palps between the antennae are visible.

16.https://www.inaturalist.org/observations/334684165

Abdominal end black or black-banded.
Veins across HW band not dark-dusted.

Both probably Potanthus mingo.


17. https://www.inaturalist.org/observations/334682679
Antennae with white spot on club.
Markings as for Isma.
Underside ochreous, with vague spots.
Isma iapis.
https://a4.pbase.com/o2/25/686825/1/132544830.SZ7JZXwf._LC86858x.jpg

[Psyche]

18. https://www.inaturalist.org/observations/334682678
Female Hyarotis microstictum.

The female have a characteristic curve cellspot ,from two spots conjoined.
See female from Satun.
https://yutaka.it-n.jp/hes/91840001.html



19. https://www.inaturalist.org/observations/334544750
Isma iapis/ protoclea.
Probably I. iapis.

The FW spots and large round head are typical.
The white spot on the antennal club is on the underside and no visible in a topdown view.
https://yutaka.it-n.jp/hes/91880001.html
https://yutaka.it-n.jp/hes/91890010.html

[Psyche]

20.https://www.inaturalist.org/observations/334684173

21. https://www.inaturalist.org/observations/334684180

Both are members of the amphimuta group, subgroup amphimuta.

The lack of a tornal white spot indicate either amphimuta or major.

In P. Malaysia they are near impossible to separate based on the undersides.

A. amphimuta.
Male UpF with noder a thread.
UnH V spot wellformed postdiscal spots regular, submarginal spots clearer.
https://www.gbif.org/occurrence/2847202551
https://www.gbif.org/occurrence/2847198400

A. major
Male UpF with a broad brown border.
UnH V spot may be distorted, postdiscal spots may be more irregular, & the submarginals faded.
https://www.gbif.org/occurrence/2847202117
https://www.gbif.org/occurrence/2847202114

20 should be correct as A. amphimuta.
21. Uncertain.

[Psyche]

22. https://www.inaturalist.org/observations/334684153
Pantoporia sandaka.

The right FW shows the submarginal orange band largely intact.
The grey band inner to it is reduced to a series of beads.


23. https://www.inaturalist.org/observations/334682680
Female Euploea eyndhovii.

The 3rd readily shows it is a female ,and the FW is unmarked.
https://yutaka.it-n.jp/dan/30660010.html

The female of E. doubledayi is marked by several prominent FW discal spots.
https://yutaka.it-n.jp/dan/30640010.html

[Psyche]

24. https://www.inaturalist.org/observations/334544741
Likely to be Allotinus sarrastes.

Two species have HW spot 6 roughly level with spots 2 to 5.

A. sarrastes
FW postdiscal band partially dislocated and is closer to the margin at the dorsum(lower margin) than at the costa.
https://www.gbif.org/occurrence/2847202791
https://www.gbif.org/occurrence/2847202800

A. portunus.
FW postdiscal band is parallel to the margin.
https://www.gbif.org/occurrence/2847203195
https://www.gbif.org/occurrence/2847203192

[Psyche]

25. https://www.inaturalist.org/observations/334688559
Male Potanthus juno.

This readily identifiable because it have only two subapical spots, ie spot 6 & 7.
A third spot 8 may be present but reduced.
