This species is known only from the northern part of the Uluguru Mountains in Tanzania where it has been recorded at 600-2,200m asl.
Habitat and Ecology
The type series was collected in forest, secondary forest, banana cultivation and bamboo. From this information, it seems that it can tolerate a degree of habitat disturbance, but probably not the complete opening of its habitat that has taken place in some parts of the Ulugurus. It is ovoviviparous, with internal fertilization, the females retaining the larvae internally in the oviduct until the birth of the toadlets.
There have been no records of this species since the original collections of the species in 1926 and 1927. In view of the amount of herpetological work that has taken place in this area, it would appear to be a rare species.
The habitat of this species is probably being lost to agricultural encroachment, wood extraction, and expanding human settlements, especially at lower altitudes.
It occurs in the Uluguru North Forest Reserve, but this area is not generally managed for biodiversity conservation. Improved management of this reserve, and the protection of other remaining forest habitat in the Ulugurus, is necessary.
It is listed on CITES Appendix I.
