Agreed. It is probably Z. hylax. Strangely the ID mark of hylax the costal spot in space 11 is missing.

What puzzled me now is where is Zizeeria karsandra in Singapore. C&P4 states it is most commonly seen in Kedawi & Singapore.
It is practically identical with Z. maha except for pale submarginal spots.
