From the IUCN Red List Species Account:

 

Range Description

This species was described from the Ngozi Crater in the Poroto Mountains, Mbeya Region, southwestern Tanzania (Blackburn 2012; T. Davenport pers. comm. September 2012). Ngozi ridge rises to about 2,620 m asl, whereas the forest in the area reaches to above 2,450 m asl (T. Davenport pers. comm. September 2012). As it is known from a single site its extent of occurrence (EOO) is estimated to be well below 100 km2.

Habitat and Ecology

While there are no observations on this frog's habitat and ecology, it is possible that it could have been collected in the montane forests surrounding the lake (Blackburn 2012). Alternatively, other habitats in the Mporoto Forest Reserve and Ngozi are montane grassland and bamboo forest (T. Davenport pers. comm. September 2012). This frog is expected to have similar ecological requirements to closely allied species, including being terrestrial and associated with leaf litter (Blackburn 2012). As with other congeners, it is presumed to have direct development (Blackburn 2012).

Population

It is currently known only from a single specimen, collected in 1930 (Blackburn 2012). There have been many surveys carried out at Ngozi by different parties over the last ten years; however, the species was never recorded in any of these (S. Loader and M. Menegon pers. comm. June 2012; T. Davenport pers. comm. August 2012). Given the lack of records since the species' description despite numerous survey efforts this frog could be possibly extinct.

Population Trend

unknown

Major Threats

All of the natural habitats of Ngozi crater are degraded and are continuing to be heavily impacted by encroachment from human activity (pole cutting and production of charcoal; S. Loader pers. comm. June 2012; logging, agricultural encroachment, burning and unregulated tourism; T. Davenport pers. comm. September 2012).


Conservation Actions

This frog's type locality is found in the Mporoto Ridge Forest Reserve (Blackburn 2012); however, management has been lacking for decades and this area is in urgent need of improved protection (T. Davenport pers. comm. September 2012).

Red List Status

Critically Endangered (CR)

Rationale

Listed as Critically Endangered given that its extent of occurrence (EOO) is estimated to be well below 100 km2, it is known from a single threat-defined location, and there is a continuing decline of natural habitats at Ngozi Crater in Tanzania. Given that numerous surveys by different parties have been unable to locate this species since its first and only collection in 1930 it is flagged as Possibly Extinct (PE).
