Strange Potanthus?

[DaveChiangMai]

Two images of the same individual from Tham Sakoen NP, Nan province, n Thailand. I can only assume this is a Potanthus sp, though I can find no match for the strange wing pattern. Suggestions please?

I believe this is an Ampittia sp.

Ah, many thanks. Not used to seeing upperside shots of Ampittia.
