This species is known from a single threat-defined location in the Uluguru Mountains in eastern Tanzania, at 1,200-1,500 m asl, and probably higher. Its extent of occurrence (EOO) is 492 km².
Habitat and Ecology
It has been found only in undisturbed montane rainforest. It is ovoviviparous, with internal fertilization and the females retaining the larvae internally in the oviduct until the toadlets are born.
Nothing is known about the abundance of this species, but given ongoing habitat loss its population is presumed to be declining (S. Loader pers. comm. December 2014).
There is ongoing decline in the quality and extent of its rainforest habitat due to agricultural encroachment, wood extraction, and expanding human settlements.
It occurs in the Uluguru Nature Reserve, which afford relatively good protection, but there is a need for continued and strengthened management to ensure the maintenance of remaining forest habitat. It is listed on CITES Appendix I. Further research is required on the population size, distribution and trends.
Red List Status
This species is listed as Endangered because its extent of occurrence (EOO) is estimated to be 492 km² (therefore its area of occupancy will also be less 500 km²), it is known from a single threat-defined location, and the quality and extent of its forest habitat in the Uluguru Mountains is declining.
Further taxonomic investigations are required on this species as more than one taxon may be represented.
