#1.https://www.inaturalist.org/observations/238938435
Trying to ID a wornout off- focused small Lycaenid is normally a tall order.
However there is one that looks matching.
Salient points.
Darkish ground.
UnH with large white-haloed spot 7, a smaller sub-basal one.
UnH margin with spot 2 largest & the upper spot 7 also largish ,both slightly white-ringed.

Compare male from Ranong
https://yutaka.it-n.jp/lyc4/80780001.html
and this observation.
https://www.inaturalist.org/observations/112692003

Verdict: Likely to be Udara cyma.

#2. https://www.inaturalist.org/observations/238938430

Another difficult genus.
Salient points.
Distinctly yellow.
Pic 1 & 4 shows a large spot 6 connecting tne main band with spot 7.
Pic 2 also shows UpH with a large spot 6.UpF
Likely to be this.
Potanthus pava.
Yellow marking ;band narrow or more often broad & continuous in the male.
Large spot 6 Uph, UnH.
Abdominal end yellow with a narrow black band in male, heavier shading in female.

Potanthus confucius is very similar ,smaller .UpH with small or no spot 6.

#3. https://www.inaturalist.org/observations/238917805

Pantoporia dindinga.
The markings & the shape of the rounded spot match.

#4. https://www.inaturalist.org/observations/238917767

Arhopala moolaiana.
Amphimuta group markings.
There is a tornal white dot & the markings markings & V spot is fat.
The upperside seem to show a female.

The tornal white dot means either A. norda or moolaiana.
A. norda have narrower marking & is much rarer.
UpF shows a uniform brown border of the FW margin.(resembles A. major.)
Confirmed A. norda.
https://www.inaturalist.org/observations/238739817



#5. https://www.inaturalist.org/observations/238737285

Likely Baoris farri.
There is a full set of spots as in Baoris farri male.
https://yutaka.it-n.jp/hes/93210001.html

The B. oceia male typically have much reduced spotting & generally darker.
https://yutaka.it-n.jp/hes/93220001.html


#6.https://www.inaturalist.org/observations/238269416

Parnara bada.
Short antennae with thick clubs; No UpF cellspot; UpH with small irregular spots.
https://yutaka.it-n.jp/hes/93050001.html



#7. https://www.inaturalist.org/observations/238269415

Oriens gola.
FW band contiguous without darkened veins.

O. golopides.
FW subapical & cellspot detached & veins darkened.
https://thaibutterflies.com/Butterflies/oriens-goloides/oriens-goloides-3/



#8. https://www.inaturalist.org/observations/237795036

Hyarotis adrastus.
Shape of cellspot is very variable.



#9. https://www.inaturalist.org/observations/237406744
Amphimuta group .There is no tornal white dot.
Either A. amphimuta or major.
Based on the well-shaped V spot this should be A. amphimuta.

[Psyche]

#10. https://www.inaturalist.org/observations/237402671

Likely to be Arhopala selta.

Cleander Group. alea subgroup.
FW spot 4 not dislocated outwards.
UnH spot 7 atop apot 6.
UnH postdiscal band fully dislocated at vein 2 (after the V spot).
Alea subgroup. Smaller UnH postdiscal band & submarginal spots/band coming close or touching.

Two members of the alea subgroup are rather similar .UnH spot 6 is bulky ,& not tapering downwards.

Arhopala selta.
Male FW margin somewhat rounded (hard to judge.).
UnH spot 6 large & widely overlapping the cellend bar.
Male Upf with wider brown border increasing to the apex.
https://yutaka.it-n.jp/lyc4f/82110001.html
Male with UpF confirmation.
https://www.inaturalist.org/observations/21937023

Arhopala phaenops.
Male FW margin more or less straight.
UnH spot 6 barely overlapping the cellend bar.
Male UpF with a narrower brown border.
https://yutaka.it-n.jp/lyc4f/82120010.html
Male with UpF confirmation.
https://www.inaturalist.org/observations/24248120

Using these two confirmed examples for comparison this looks correct as A. selta.



#11. https://www.inaturalist.org/observations/237397408

Arhopala amphimuta.

Amphimuta group. Small tooth at vein 2. No white tornal spot.
The UpF almost complete blue confirm the ID.

Female Neptis omeroda.

Neptis harita.
FW postdiscal spot 2 often lunulate or with crescent margin.
UpH submarginal marking form a catenulate (chain-link like) band.

#13. https://www.inaturalist.org/observations/237279351

Male Allotinus.

4 species have very similar markings

A unicolor. FW 15-16mm.
FW series of spots not dislocated in the middle.
HW spot 6 rounded & placed well inside of spot 5 & 7.
Male.

Allotinus horsfieldi FW 18-23mm.
FW postdiscal spots dislocated in the middle.
HW spot 6slightly inside of spot7.
Ground light beige with ochreous brown markings.
Male.
https://thaibutterflies.com/wp-content/uploads/2016/07/Allotinus-horsfieldi-permagnus-2.jpg


Allotinus leogoron FW 18-22mm.
Similar to A. horsfieldi.
Ground whitish with darker grey brown markings.
Male.
https://inaturalist-open-data.s3.amazonaws.com/photos/29684555/large.jpeg


Allotinus corbeti.FW 10-11mm.
Rounded Fws. FW band dislocated.
UnH spot 6 just about under spot 7 & may merged with it.
Female.
https://thaibutterflies.com/Butterflies/allotinus-corbeti/

This looks like a male Allotinus corbeti.
A. corbeti is like the tiny grass blue Zizula hylax flitting in the garden

Both A. horsfieldi & leogoron would be nearly three times bigger.

The size is the deciding factor.
