In the open wing mode the two large ocelli on the hind wing are separated by a smaller ocellus. In most forms I have seen the two large ocelli are next to each other. The side view shot indicates that it's a Ypthima horsfieldii humei (Malayan 5 Ring). Would appreciate a comment. Thank you.

It is a female Ypthima fasciata.
The upperside spotting is typical & the highly contrasted markings denote a female.
On the underside the two HW bands are broad & parallel , & almost straight.
The small ocelli are arranged more or less in line & marked by a dark fascia (band).

In Y.baldus & horsfieldii the 2 HW bands are less defined ,curved, the outer band undulate.
The submarginal ocelli are of different sizes & widely out of line , being in groups of two.

Thanks again. Dr Seow. Thought the Rings would be easier to ID!
