This species is known only from a single forest fragment in the Ukaguru Mountains in eastern Tanzania where the only specimens were collected at 1,840 m asl. It has not been found in other, better-surveyed parts of the Eastern Arc mountain chain, so the extent of occurrence (EOO) has been estimated as 95 km
Habitat and Ecology
The only specimens were collected in moist valleys but are absent from the adjoining drier montane forest (M. Menegon pers. comm. June 2012). It is arboreal. Its breeding is unknown, but the presence of large numbers of pigmented eggs in the only known specimens suggests that it is neither a live-bearer, nor a direct developer. However Channing et al. (2012) suggested that this species may have direct development.
Only four specimens are known and a targeted search in 2007 did not find any specimens (M. Menegon pers. comm. June 2012), but due to ongoing habitat loss its population is suspected to be decreasing.
The forests in the Ukaguru Mountains are poorly protected; they are threatened by agricultural encroachment and human settlement.
This species occurs in the Mamiwa-Kisara Forest Reserve. Urgent survey work is required to determine the biology and population status and trends of this species and the limits of its range.
