I was looking at some Australian butterflies when I saw that M. perseus is found there and voila ! there is a dry season form which looks very similar to this.

A search brings up this dry season form of M. perseus from India.
The wing perspective is distorted and the colour rendition is too dull.

The key feature is the sub-basal dark line which is very irregular and matches your pic.
The dark line in M. suaveolens is too smooth, & moreover it is very unlikely to have stray into KPN from far north.
