This species was previously only known from the East Usambara Mountains in northeastern Tanzania. However, records from the Udzungwa Plateau and Udzungwa Scarp in southern Tanzania (with records from Dabaga and Masisiwe), and the Nyika Plateau in northern Malawi, which were previously attributed to Amietia viridireticulata, are now included in this species' range (Channing et al. 2016). Furthermore, Channing et al. (2016) also confirmed records from the Uluguru, Ukaguru, and West Usambara Mountains, the Southern Highlands and Kilombero Valley in Tanzania, and the Taita Hills of Kenya. It has been recorded between 400–1,740 m Asl, but probably also occurs higher, at least to 2,000 m Asl. Its true distribution is unknown, but it is probably also present in the intervening highland areas. Its current range is believed to represent four threat-defined locations.
Habitat and Ecology
It lives along margins of streams in forest. It breeds in water by larval development.
It is quite common in the East Usambaras, but was previously identified it as Amietia angolensis. However, due to ongoing decline in the quality and extent of its habitat, it is thought to be decreasing.
It is probably threatened by deforestation for slash-and-burn clearing techniques, logging and wood collection, plantations of exotic tree species (such as teak, pine or eucalyptus), expanding human settlements and agricultural activities, and also by the subsequent siltation of streams.
It occurs in the Udzungwa Forest Reserve, Amani Nature Reserve, Uluguru North Forest Reserve, Kilombero Nature Reserve, Dabaga New Forest Reserve, Mundufi Scarp Forest Reserve, Kitulo National Park, and Nyika National Park.
Ongoing and improved protection is needed for the areas in which it is known to occur.
Surveys are needed to determine the population size and distribution.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution and presumed large population.
This species has previously been identified as Amietia angolensis, which has recently been found to harbour cryptic species (Channing and Baptista 2013). A. viridireticulata was synonymized under this species by Channing et al. (2016).
