A previously undescribed, montane forest-dwelling Potanthus is reported as a species endemic to Taiwan. Its closest relatives are suggested to be P. flavus, distributed from the continental Asia to Japan, and P. niobe from the Philippines, based upon two synapomorphies in the genital structures of both sexes. This new species inhabits altitudes higher than all the congeneric members previously known from Taiwan. Its presence fills the gap in the P. flavus + P. niobe distribution between the Philippines and the Asian continent, demonstrating a biotic connection between these regions.
