What an amazing and timely discovery(just in time for xmas)
#1 is definitely damona as both the dorsal and ventral(ground colour and shape of post-discal band) are typical of damona . So are #3 and #4.
#2 looks different from the rest and is most likely dieneces from the less darkened veins on the dorsal hindwing(although this seems inconsistent) and the more yellowish ground colour and more scalloped post-discal band on the ventral surface.
I think this sequence shows the differences between these two similar spp. very nicely and will be very useful for spotting more damona in the future.
There is one more very rare species, Rapala cowani, whose type locality is Singapore but it's most likely extinct now, even though there is a very slim chance that it's still lurking in the mangroves.
