This species is currently only known from the Chome Forest Reserve (a proposed Nature Reserve), South Pare Mountains, Tanzania, at ca. 1,900 m asl (Loader et al. 2011). Additional amphibian surveys have been conducted in areas close to the type locality, but no recent records have been recovered (S. Loader pers. comm. November 2011). This, however, could be an artefact of sampling, given the species' cryptic nature. If it is restricted to the South Pare Mountains the maximum estimated forest cover would be between 139-333 km2 (S. Loader pers. comm. November 2011).
Habitat and Ecology
The only two collected individuals were found in the leaf litter in montane forest (Loader et al. 2011). There is no information about any other aspect of this species' biology, although it is thought that this frog may breed by direct development based on what is known of other members of this genus (S. Loader pers. comm. November 2011).
It is currently known from only two specimens collected in a survey in 1999 (Loader et al. 2011; S. Loader pers. comm. November 2011). However, this is a small and cryptic frog, so the lack of subsequent records in more recent surveys may not necessarily reflect rarity or changes in population (S. Loader pers. comm. November 2011).
There are large-scale logging activities taking place in or near the Chome Forest Reserve (Loader et al. 2010); however, the impact of these activities in the reserve itself is not known.
It occurs in a proposed nature reserve, which is currently designated as the Chome Forest Reserve (S. Loader pers. comm. April 2012, Loader et al. 2011), a 140 km2 protected area (WDPA 2010). However, it is unclear whether the protection currently afforded is effective (S. Loader pers. comm. November 2011). The reserve needs to be managed to limit the impact of logging on the remaining forest, and additional research is needed to determine this frog's distribution, population status, ecological requirements and tolerance to habitat alteration (S. Loader pers. comm. November 2011).
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been described, and there is still very little information on its extent of occurrence, population status, threats and ecological requirements.
There are no taxonomic changes or current doubts about the validity of this taxon (S. Loader pers. comm. November 2011).
