Range Description

This species is known only from the northern face of Mount Tchabal Mbabo, at 1,950-2,000 m asl, in Adamawa Province in western Cameroon (Lawson 2000). It may occur in neighbouring Nigeria and other mountains in the region such as Mount Nghana (T. Doherty-Bone pers. comm. October 2012). Two herpetological surveys (including pitfall trapping) of Mount Tchabal Mbabo conducted since the 1997 survey that led to its description (1998, 2000; 14 days each in the dry season) failed to locate caecilians (Herrmann et al. 2006). Mount Tchabal Mbabo has been surveyed only sporadically, probably because of limited accessibility and distance from most urban centres (Doherty-Bone et al. 2011). Using its known range as a proxy, the estimated extent of occurrence (EOO) is 39 km2.

Habitat and Ecology

The only known specimens were found on steep forested slopes. The only other habitat in the area is heavily grazed pastureland, the suitability of which is unknown for this species. Its breeding ecology is unknown.

Population

The three known specimens were all collected in 1997, about an hour from the same locality, but despite a week's work in the area no others were encountered. Thus, the abundance and population trend of the species are unknown.

Population Trend

unknown

Major Threats

It could be threatened by habitat loss as the remaining forest habitat on Tchabal Mbabo is confined to galleries and steep slopes because of clearing for pasture land. While most of the forest habitat has now been cleared, the remaining forest is still threatened by fire used to create pasture land.

Conservation Actions

Tchabal Mbabo has been proposed as a National Park, which, in view of past habitat destruction, would provide much-needed protection of the species' remaining habitat. Further research is needed on the species' taxonomy, distribution, population status, natural history and threats.

Red List Status

Data Deficient (DD)

Rationale

Listed as Data Deficient in view of continuing uncertainties as to the extent of its distribution, its population status and ecological requirements.

Taxonomic Notes

The systematic status of this species in relation to Crotaphatrema lamottei is uncertain as they could be the same species; more research is needed to clarify this relationship (T. Doherty-Bone pers. comm. October 2012).
