This is the first record in Thailand. The butterfly is rare in lowland forest.
In general, the butterfly fauna of Langkawi and Koh Tarutao are often identical. However, the example of Koh Tarutao is curiously seems to be ssp.rubidifascia which is distributed in mainland Malaysia, rather than ssp.siamica in Langkawi. Tsukada,1991 described revivo in W.Malaysia, which is considered to be synonym of rubidifascia. In addition, Holotype of Cameron Highland is rufidifascia, however paratypes in Kedah are considered to be ssp.siamica. Further taxonomic study and distributional research are needed.
