Country distribution from AmphibiaWeb's database: Tanzania, United Republic of
IUCN (Red List) status: Endangered (EN).
This species is known with certainty only from the East Usambara Mountains (including the Magrotto ridge) and the Nguu Mountains in north-eastern Tanzania. It ranges from 600m to at least 1,200m asl.
Habitat and Ecology
It is found in lowland and montane forest, and is sometimes associated with wild bananas. It appears to be very rare in heavily disturbed forest or in open areas. However, it is locally abundant in stands of introduced bamboo in the Amani Botanic Garden. The eggs are deposited in hollow bamboo stems or leaf axils (and perhaps tree holes) where water is trapped, and where the larvae develop.
It is generally an uncommon species, and is very hard to find outside the breeding season. However, it is easily found in the Amani Botanic Garden in the East Usambaras during the breeding season due to the extensive stands of exotic bamboo, with which it is closely associated (30% of holes in broken bamboo stems have been found to contain eggs, larvae or adults).
It is almost certainly adversely affected by ongoing forest loss, especially for small-scale agriculture. The habitat in the East Usambaras has recently come under serious threat as a result of the activities of illegal gold miners.
It occurs in the Amani Nature Reserve, and in several forest reserves; there is a need for increased protection and improved management of these and other reserves in the East Usambaras.
