Is this a Polytremis lubricans or could it be a Pelopidas assamensis?

It can be quite difficult when the HW cellspot is missing.

The short stubby antennae suggest Parnara, but is due to the antennae being held sideway & the FW cellspot discount Parnara.

Polytremis lubricans is quite different in colour even when worn.

Borbo cinnara with extra spots is neater; whiter 'face'; FW spot 3 crescentic margin.

Pelopidas agna would have the FW spot 3 narrow.

The individual is a male (from wingshape & abdominal end).

If it is large it is probably P. conjunctus.(Against P. conjunctus is it appear to have a single upper FW cellspot.)
If it is small probably P. mathias.
