From the IUCN Red List Species Account:

 

Range Description

This species is known only from two general areas in south-western Cameroon: Apouh and Koupongo, near Edéa, in southern Cameroon (these two localities are 50 km apart, and are separated by the Sanaga River). Records from the northern part of Korup National Park, east to Nguti, and north to Mount Nta Ali (Lawson 1993) are based on misidentifications and refer to Astylosternus diadematus (J. L. Amiet pers. comm.). Its elevation range is unknown, but it is likely to be a mid-altitude species (M.-O. Rödel pers. comm. July 2016). Its EOO is 1,025 km2.

Habitat and Ecology

This species lives in and near flowing water in lowland forest, and can survive in tall, secondary forest. It breeds in small streams and in marshy depressions with very small, superficial streams.

Population

It appears to be a rare species occurring at low densities in the southern parts of its range. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

The major threat to the species is habitat loss and degradation due to clearance for agricultural land, human settlements and logging.

Conservation Actions

Conservation Actions
This species might occur in the Douala-Edea Forest Reserve and Lac Ossa Wildlife Reserve. 

Conservation Needed
The remaining forest habitat in south-western Cameroon is urgently in need of protection.

Research Needed
Surveys are required to verify whether this species occurs in any protected areas, and more accurate species descriptions are required for the genus to aid identification of specimens (M. Hirschfeld pers. comm. July 2016).

Red List Status

Endangered (EN)

Rationale

Listed as Endangered because its extent of occurrence (EOO) is 1,025 km2, it is known from fewer than five threat-defined locations, and there is decline in the extent and quality of its habitat in Cameroon.
