Previously published Red List assessments:

Geographic Range [top]

Range Description:This species occurs in the Livingstone, Mahenge, Udzungwa Scarp, Rubeho, North Uluguru, Nguru, Ukaguru, and Nguu Mountains of Tanzania, representing 8 threat-defined locations. Its altitudinal range is 600-2,200 m asl, its extent of occurrence (EOO) has been estimated as 39,726 km2 and its area of occupancy (AOO) has been estimated 593 km2. There have been a number of new localities added since the new assessments (Livingstone, Mahenge, Rubeho, Nguru); the records from Nguu were incorrectly allocated to Afrixalus dorsimaculatus and have been moved to this species.
