Notes
This is the first record in Vietnam. The first record from Thailand is obtained a specimen in Pua dist., Nan in Mar.1991 by local catcher.
The butterfly is locally common in montane forest at moderate to high elevations (alt.1000m - 1700m).
The species was described as a subspecies of selenophora, however is raised to independent species by Koiwaya,2016. And He pointed out that the above specimens, which I have illustrated as selenophora on my WEB, are this species. Therefore I treat yui as a distinct species following Koiwaya,2016 provisionally. However the relationship of yui, selenophora and whitei is still unclear. Further taxonomic study is needed.
