These Pelopidas can be very tough to ID.

P. mathias is greyer on the underside & also have more uneven shadings.

In P. agna UnH is more uniform in colour.

The UnH looks uneven & is also greyer than in post 12.
UnH spot 7 is more often present in P. mathias.

The upF alignment of the two cellspots seem to move away from the space 1b spot suggesting P. agnabut this often variable.


Overall I think it is P. mathias but certainly not confident here.
