1. Celatoxia marginata.Female.
Among the genera with a white dot at the antennal tip include Celastrina, Udara ,Celatoxia, Lestranicus & Callenya.

C. lavendualris have spots with white halos, while C. argiolus have small spots.

This one have heavy postdiscal spots so most of the other genera can be excluded.
