Which genus is this skipper?

[DaveChiangMai]

I have only this one image of this individual, taken in extreme west Thailand. It is unlike other images in my collection, but I am having a hard time to decide which genus this is even. The spot in space 1 of the forewing rules out quite a few species, but I am still undecided if this is Pelopidas (conjunctus?), or Polytremmis (lubricans?) Some pointers would be very helpful please. As only one image makes ID to species hard, but I would like to know the genus.

With thanks.

This is a tough one.
Pelopidas conjunctus have yellow FW spots; always 3 subapical spots & dark cilia.

Polytremis lubricans have distinctive deeper yellow FW spots.

It looks like the female(spot in space 1b denotes a female) of one of three species of Caltoris which have two full FW cellspots.

One more uncertainty is the pale highlight on the right HW.
Normally this suggest a band.pale patch on the underside.
eg Halpe zema.

However I think it is one of the Caltoris.

Thank you for the notes. Good to see it's not just me that is confused! Many thanks.
