This species is known from a single valley in the Uzungwa Scarp Forest Reserve, above Chita, on the escarpment of the Udzungwa Mountains, in eastern Tanzania. It is found from 1,500-1,650 m asl. Despite surveys between 2000-2010 and 2013-2014, it has not been found at other localities in the Udzungwa Mountains (M. Menegon and E. Tonelli pers. comm. December 2014). Its extent of occurrence (EOO) is estimated at 15 km².
Habitat and Ecology
It is leaf-litter species restricted to montane rainforest. Presumably it breeds by internal fertilization like other members of the genus.
The species is quite common in one tiny area. Ongoing population reduction is inferred given that it appears to be a habitat specialist and there is ongoing disturbance in the area.
Anthropogenic forest disturbance to this species' habitat has been reported to be ongoing, and includes tree and pole cutting, charcoal burning sites, human trails and pit sawing sites from felling of large trees (Rovero et al. 2012).
This species occurs in the Udzungwa Scarp Forest Reserve which is soon to be included in a nature reserve (see Marshall et al. 2007), but is not currently a well-protected area. The species is listed on CITES Appendix I. Since 2009, it has been monitored by the Whitley Wildlife Conservation Trust, Science Museum of Trento (Italy), Paignton Zoo and the Tanzania Forest Conservation Group (TFCG) (Seki et al. 2011).
Red List Status
Critically Endangered (CR)
This species is listed as Critically Endangered because its extent of occurrence (EOO) is limited to 15 km², it is known from a single threat-defined location, and there is ongoing decline in the quality and extent of its habitat in the Udzungwa Mountains.
