From the IUCN Red List Species Account:

 

Range Description

This species is found on Bioko Island (Equatorial Guinea), along the Atlantic coastal region of Cameroon and in extreme western DRC, between 30–1,218 m Asl (Evans et al. 2015). It is possible that this species also occurs in mainland Equitorial Guinea, Angola and the Republic of the Congo (Frost 2015), although this requires verification.

Habitat and Ecology

On Bioko Island, this species has been found in both forested and disturbed areas (Evans et al. 2015). Individuals were caught in a stagnant river valley in pools of standing water (B. Evans pers. comm. February 2016). It lives syntopically with Xenopus calcaratus and Xenopus mellotropicalis, and has a trill-type call (Evans et al. 2015). Its breeding is unknown, however it is presumed to be similar to other species in the genus with eggs laid in water and tadpoles developing in slow moving and stagnant water (B. Evans pers. comm. February 2016).

Population

Little is known about the population of this species however, due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

The main threats to this species is habitat loss and alteration caused by conversion to agricultural land and logging.

Conservation Actions

Conservation Actions
This species has been found in Basilé National Park in south Bioko.

Research Needed
Research on the population, distribution and ecology of this species is required.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern due to its wide distribution and presumed large population.

Taxonomic Notes

This species was previously confused with Xenopus fraseri prior to its description (Evans et al. 2015).
