Justification: Platycypha auripes occurs in forest streams of the Eastern Arc Mountains. Extent of occurrence is 16,676 km² and area of occupancy 48 km². It is assessed as Endangered in view of its restricted range in the East Usambara, Uluguru and Udzungwa Mts and only 5 locations with trustworthy records. The forest areas of all three mountain ranges have been largely destroyed during the last century and currently only parts of the East Usambara and the Udzungwa Mts experience some kind of protection, while at all other sides the forests are cleared or logged. The Tanzania Jewel is sensitive to forest destruction and is replaced by the Common Dancing Jewel, if the habitat is disturbed.
