|Taxonomic Notes:||We follow Pickersgill (2007) in removing this species from the synonymy of Afrixalus uluguruensis. However, molecular data show that this might represent more than one species (S. Loader pers. comm. Oct 2015).|
|Red List Category & Criteria:||Endangered B1ab(iii) ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Loader, S. & Pickersgill, M.|
Listed as Endangered because its extent of occurrence is 4,404 km2, it occurs in two threat-defined locations, and there is continuing decline in the extent and quality of its forest habitat in the Usambara Mountains of Tanzania.
|Previously published Red List assessments:|
|Range Description:||This species is restricted to the East and West Usambara Mountains in Tanzania. While its altitudinal range is not fully known, it is a species of medium to high altitudes, and its extent of occurrence has been estimated at 4,273 km2. The record from Nguu was incorrectly allocated to this concept in the 2008 assessment; it has been removed and is now found under the assessment for Afrixalus ulugurensis.|

|Population:||It is abundant where it occurs, but due to ongoing decline in the quality and extent of its habitat, its population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is a forest-dependent species and does not survive in degraded habitats. It breeds in swampy valley bottoms and temporary pools in closed-canopy forest.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||The main threat is habitat loss due to agricultural encroachment, logging, and expanding human settlements. Its habitat in the East Usambara Mountains came under serious threat in the past as a result of the activities of illegal gold miners, but this has apparently ceased (S. Loader pers. comm. Oct 2015).|
It occurs in the Amani and Nilo Nature Reserves in the East Usambaras, which are relatively well-managed for biodiversity. It also occurs in the Mazumbai and Ambangula Forest Reserves in the West Usambaras.
Improved site and habitat protection and management are needed.
Further research is needed on the species distribution, population and taxonomy.
