“…P. yunnanensis was formerly considered a subspecies of P. philippensis, but genetic and morphological analysis shows it to be a distinct species (Francis, 2008, Oshida et al, 2004, Oshida et al, 2010, Song et al, 2012, Yu et al, 2006. It is sympatric in western Yunnan with at least four other Petaurista species: P. alborufus, P. caniceps, P. elegans, and P. petaurista; P. philippensis is broadly sympatric but occurs at lower elevations (up to 2000 m), while P. xanthotis occurs in northwestern Yunnan, but in spruce forests at higher elevations (Francis, 2008, Smith & Xie 2008.…”
