Male curetis bulis.
UnH with postdiscal spot 6 tucked under spot 7; submarginal spot 6 & 7 in line.
This upperside with extensive black areas on the HW is diagnostic.

Female Euploea phaenareta.
E. phaenareta have large white spots on the FW apical area.
In flight, the FW apices are noticeably white.
https://yutaka.it-n.jp/dan/30740010.html
https://yutaka.it-n.jp/dan/30560010.html
E. phaenareta is urbanised because one of its hostplant ,the Pong Pong Tree (Cerbera odollam) used to be planted as a roadside tree.

#3B. https://www.inaturalist.org/observations/199633485
Isma miosticta.
The antennal club has a white spot & the wing margins are weakly chequered.
The arrangement are as in I. miosticta.
Note spots are well separated & spot 2 have its apex cut off.
https://yutaka.it-n.jp/hes/91950001.html
#3C https://www.inaturalist.org/observations/198633041
Isma species, probably I. damocles.

#3D 1.https://www.inaturalist.org/observations/198299410
Male Pelopidas mathias .
At first this look like Borbo cinnara missing a spot.
There is a faint HW cellspot in the correct position, ie at the origins of veins 6 & 7.
This can be compared to the image below (probably agna) which shows the spot clearly.
https://baliwildlife.com/encyclopedi...branded-swift/
The strong grey tinge IDed this as mathias.
#3D,2. https://www.inaturalist.org/observations/198299409
Male Caltoris malaya .
There is no upper cellspot visible, & the pale area on the antenna minimal (mainly on the underside.).
The male is ferruginous ie rusty-brown & the female more ochreous.

Polytremis discreta .
Two species are very similar with the HW spots arranged in a distinct manner.
They also been transferred to another genus Zenonoida by some authors.
P. discreta .
Spots are whiter & HW tornal cilia whitish.
https://wingscales.com/Hesperiidae/P...creta-discreta
P. eltola .
The spots are usually slightly more yellowish & the HW tornal cilia yellow.

The alitaeus group of Arhopala.
In a previous thread I called this the pseudomuta group, which is incorrect.
The main species are A. alitaeus, pseudomuta, ariana, aida & elopura.
A few more may be dismissed.ie A. arianaga (montain), sintanga & havilandi (mainly in the south.
A.alitaeus . FW margin slightly rounded, spots large rounded &strongly contrasted.
https://www.butterflycircle.com/chec...le_Chng_02.jpg
[I]A. pseudomuta.[/I FW margin slightly rounded ,spots slightly rounded & moderately contrasted.
https://www.butterflycircle.com/chec...1---Horace.jpg
A. elopura. Fw margin slightly convex, spots with straight margins & poorly contrasted. Male UpF border a thread.
https://upload.wikimedia.org/wikiped...raMUpUnAC1.jpg
A. ariana. FW margin fairly straight; spots deeper contrasted than elopura, male UpF dark border narrow.
https://en.wikipedia.org/wiki/Arhopa...naMUpUnAC1.jpg
A. aida. FW margin straight ; markings narrower, ground may be purple washed; male UpF dark border broad.
https://en.wikipedia.org/wiki/Arhopa...aMFUpUnAC1.jpg
# 7 https://www.inaturalist.org/observations/201085319
Uncertain. Too blur worn.
# 8 https://www.inaturalist.org/observations/200493901
Probably A. pseudomuta .
FW margin rounded, markings moderately contrasted.
#9. https://www.inaturalist.org/observations/201083667
#10 https://www.inaturalist.org/observations/201083666
#11 https://www.inaturalist.org/observations/201083665
#12 https://www.inaturalist.org/observations/200887586
These four have the markings as in A. pseudomuta .
The FW margin is slightly rounded , the contrast moderate.
They should be correct as A. pseudomuta .
#12 has a slight aberration in tha HW postdiscal spot 6 is missing.

This have been delt before. It should be A. amphimuta.
Pic 4. The upperside extensive blue is that of male A. amphimuta or moolaiana .
https://inaturalist-open-data.s3.ama...070/large.jpeg
Pic 1 seem to show a tornal white spot, but the spot is pink & looks to be part of the leaf blemish.
https://inaturalist-open-data.s3.ama...826/large.jpeg
pic 6.The same individual on the same leaf clearly shows there is no tornal white spot.
https://inaturalist-open-data.s3.ama.../original.jpeg
pic 2. The upperside is that of a female, species uncertain & should not belong here.

Too blur to id.
#21. https://www.inaturalist.org/observations/155945509
Probably male A. amphimuta.
There does not seem to be a white tornal dot.
Ideally the shot should be taken on a darker background.
#22. https://www.inaturalist.org/observations/147896834
Likely male A. pseudomuta .
The spots are more contrasted than usual, but otherwise a good match.
#23. https://www.inaturalist.org/observations/151480388
Should be male A. moolaiana.
The upperside is that of A. amphimuta or moolaiana.
There is a white tornal spot although a bit weak.
A. moolaiana.

Many examples of A. major shows a trace of a white tornal spot.

The male UpF have a broad brown border.
