You certainly brings up some intriguing possibilies.
Pic 1 looks lke a 6-ring but a number of things are not right.
The eyespots are rather big & arranged in 2 main groups so that they are out of alignment. In the 6-ring the spots are all small & more or less in line.
The 2 black stripes on the hindwing should be continuous (not broken) straight (not curved) & quite broad.
I am inclined to believed this is a Malayan 5-ring with an & extra spot in space 4.
An upperside shot will help.
Pic 2 & 3 is probably a Malayan 5-ring missing a spot in space 5.
There is a possibility it is a new species Y. nebulosa.
In Y. nebulosa the black stripes on the hindwing are faint & the eyespot in space 3 is smaller than that in space 2 (as here).
TL Seow
PS. C&P4 states in line 6, there is always an ocellus(eyespot) in space 5 for Y. baldus, horsfieldi & nebulosa.
In line 3 it states never an ocellus in space 5 for Y. huebneri & iarba..
Since this is obviously not Y. huebneri & the lower 3 spots are out of alignment it is possibly Y. iarba.
PS2. There is just too much similarity with Y. horsfieldi.
I have to say it is this species missing a spot.
