From the IUCN Red List Species Account:


Range Description

The distribution of this species is poorly known, but all confirmed records are from northeastern and eastern Tanzania. There are records from Mombo at the foot of the West Usambara Mountains, Kambai and Longuza Forest Reserves in the foothills of the East Usambara Mountains, and Morogoro at the foot of the Uluguru Mountains. There are unconfirmed records from coastal Kenya at Kilifi Creek and Kwale. It appears to occur at low elevations up to around 500 m asl.

Habitat and Ecology

This species is the forest-dwelling equivalent of Arthroleptis stenodactylus. It occurs on the floor of lowland forest and in recently cleared areas. It is not clear how long it can survive in deforested areas. It presumably breeds by direct development without a larval stage.


It can occur at high densities in suitable locations.

Population Trend


Major Threats

More information is needed to determine the long-term adaptability of this species to loss of forest habitat. It can clearly adapt to some level of deforestation, but it is not clear that it can persist in completely open up areas.

Conservation Actions

It occurs in the Longuza and Kambai Forest Reserves. Further research is needed to determine the distribution of this species, and its conservation needs.

Red List Status

Data Deficient (DD)

Taxonomic Notes

We follow Pickersgill (2007) in removing this species from the synonymy of Arthroleptis stenodactylus. However, this species was resurrected simply "since it's the earliest applicable name [Pickersgill] could find" (Pickersgill, 2007; p. 309) and without reference to the type material. Specimens referred to this species by Pickersgill (2007) may indeed represent a valid species though it is unlikely to correspond to Arthroleptis lonnbergi (D. Blackburn pers. comm. July 2010).
