This species is known only from the type specimen, from Tumbo Island, off the cost of Guinea.
Habitat and Ecology
There is no direct information on its habitat or ecology, although it is likely to be a terrestrial species in lowland forest. Like other members of the genus, it presumably breeds by direct development, and is not dependent upon water.
There is no information on the population status of this species. There have been no records in almost 120 years, but this is probably largely due to the severe taxonomic problems associated with Arthroleptis species, which makes it extremely hard to identify species in many parts of Africa.
There is no information on major threats to this species.
It is not known whether it may occur in any protected area. Taxonomic research is needed to clarify the identity of this taxon.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing doubts as to its taxonomic validity, as well as absence of recent information on its extent of occurrence, status, threats and ecological requirements.
There are major taxonomic problems with the genus Arthroleptis through much of Africa. In many cases, the available names can be referred only to museum specimens, not to animals in the field. This is because the identification of these species frequently depends more on their vocalizations than their morphology. In the past, Arthroleptis bivittatus has been confused with Arthroleptis taeniatus, which is clearly a distinct species. It is possible that A. bivitattatus is a synonym of A. poecilinotus, but more field observations are needed to confirm this (Perret 1991).
