Photographed in Mae Hong Son, nw Thailand, mid elevation forest. The single cell spot on upper forewing, two spots on upper hindwing and general spot configuration on the upper forewing to me makes this likely P. bevani, or possibly B. cinnara.

However, the large size and positioning of the spots in a long curve on the under hindwing do not really match either of these species. Closest I can see is P. bevani, but non of my images of this species, nor images in the literature or on the web show this spot size and patterning.

I would be very grateful for the correct ID on this. With thanks.
