Scientific Name: Arthroleptis lonnbergi Nieden, 1915
Taxonomic Source(s): Frost, D.R. 2014. Amphibian Species of the World: an Online Reference. Version 6 (27 January 2014). New York, USA. Available at: (Accessed: 27 January 2014).
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).

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2010
Date Assessed: 2008-01-02
Assessor(s): Pickersgill, M.
Reviewer(s): Stuart, S.N. & Cox, N.A.
Listed as Data Deficient since it has only recently been removed from synonymy, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.

Geographic Range [top]

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.

Current Population Trend:Unknown
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

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.

Threats [top]

Major Threat(s): 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 [top]

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.
