Population justification: The population in the Udzungwas is known from eight localities (Dinesen et al. 2001) and is guessed to exceed 10,000 individuals (L. Dinesen in litt. 2007), because the stronghold for this species in the high altitude part of the Udzungwa forest is likely to be largely unaltered (L. Dinesen in litt. 2016). However, the total population of Nyumbanitu and Ndundulu Forests and Udzungwa National Park has been estimated at possibly no more than 2,500 individuals (L. Hansen in litt. 2007). The range of 10,000-19,999 individuals therefore remains as a preliminary population estimate requiring further documentation. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Trend justification: The species's population is suspected to be in decline owing to the clearance of forest in parts of its range, although the likely rate of decline remains unquantified.
