Wow! This is a surprise.

I have look at CD27 for a long time & it does not look like U. placidula/cyma which have spot 7 larger & prominently darker than the other spots.
This leaves only dilecta & rona & it does not look like dilecta.
There is a hint of dark blue on the upperside.

Still a full upper is necessary for confirmation
Subspecies catius is the race in peninsular Malaysia.
