Post 1.

Udara dilecta
This usually can be Id'ed by the smallHW costal spot 7 & the postdiscal spots widely out of line with spot 2 shifted well in.

The 2nd does look like C. lavendularis but try as I might I can't see the white spot on the antenna.
You may have other shots that show this.

It also appeared to be rather white.

If it is not Celastrina then it can only be U. placidual or cyma.

It looks closely like U. cyma because the costal spot 7 is large & dark & it is whiter.
Not sure if cyma's range extend that far north.

TL Seow:Cheers.

There is no white spot on the antennal club, so it is not Celastrina.

It is Udara & seems to be U. cyma.

TL Seow:Cheers.

Your Polytremis should be P. eltola.
The HW tornal cilia of P. discreta is white above but also whitish on the underside.

The HW tornal cilia in P. eltola is ochreous on both sides.

Thanks Dr. Seow, if it is Polytremis eltola is a new species to me ;)

Udara cyma is recorded only for Peninsular Thailand.

Could it be another Udara (Placidula or dilecta)?

It isw probably U. placidula.
In genral placidula is greyer & spot 7 smaller.
