You have a male (check the sex brand on the hindwing) of Danaus genutia genutia f. intermedius.

Thanks for the illustration SC, it makes it so much clearer. Unfortunately, I don't have the knowhow, or good enough photos to do this.

Incedentally, the sex brand is the easiest way to sex all the Danaus and Tirumala species. Unfortunately, it won't work fo the Glassy Tigers (Parantica, Ideopsis species)!
