colour is entirely white (the hindwings tend to be pinkish in similar species),
and the fasciae fine, red, obliquely curved in the male and straighter in the
female. The female has three red discal dots, but only two are evident in the
male, the position of the most distal one being covered by the costal fringe of
the taxa brought into synonymy have very similar facies and male genitalia.
There may be some subspecific distinction, particularly with relation to the
robustness and number of the spines in the aedeagus vesica. These are finer,
longer and more numerous in Bornean material relative to a typical Javan
specimen (slide 4822). There is also variation in the thickness of the fasciae:
these are very fine in specimens from Borneo, Java and Peninsular Malaysia, but
thicker in those from Bali, Sumatra and Palawan.
five Bornean specimens have been seen from both lowland and lower montane forest
(to 1000m) including on limestone.
