Image from Doi Lang, northern Thailand. I actually took the photo in August 2011, and had originally identified it as
Lestranicus transpectus. But that now looks incorrect. The heavy pale edges to the underside spots would be a feature of Celastrina lavendularis, but several features are not correct including the arch of 4 distinct spots and the lower base of the hindwing.
Seems to match Monodontides musina. Thoughts please.
