Range Description

The specimens accepted for the current concept of this species are the in the Simandou Range of southeastern Guinea: from the type locality close to the village of Morigbadougou, on the Dofa River on the northeastern flank of Pic de Fon (Simandou) mountain; and from Tiyeko near Traorela, a village to the northwest of Pic de Fon, in Haut Niger National Park. Its elevational range is unknown, and its current and tentative extent of occurrence (EOO) is 1,691 km2 and area of occupancy (AOO) is 1,258 km2.

Other records from Mount Nimba area in Guinea and others in Sierra Leone require confirmation and are excluded from this assessment (M.-O. Rödel, L. Sandberger and J. Penner pers. comm. June 2012).

Habitat and Ecology

This species is found close to rivers in gallery forests at the type locality. There is no habitat information for the site at Tiyeko, but it presumably lives in the forest habitats within the park. At Mount Nimba, it was found in primary forest along river (L. Sandberger pers. comm. June 2012). It is not believed to be tolerant of habitat degradation and is presumably a larval developing species, like other members of the genus.

Population

This species appears to be rare or restricted to specific primary habitats. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

In the Simandou Range, remaining habitat is fragmented into small patches, and logging to clear land for agriculture as well as for commercial purposes and bushfires are major threats. The type locality is heavily threatened by open cast mining.

Conservation Actions

Conservation Actions
This species is found in the Forêt Classée du Pic de Fon (although this does not protect against mining). It is also found in Haut Niger National Park, although a survey in 2011 did not record this species (L. Sandberger unpubl. data).

Research Needed
Further research on the distribution, population size and also the taxonomy is needed (L. Sandberger and J. Penner pers. comm. June 2012).

Red List Status

Data Deficient (DD)

Rationale

Listed as Data Deficient as there are continuing doubts as to its taxonomic validity.

Taxonomic Notes

The taxonomic status of this species requires resolution as it is likely to comprise several species (M.-O. Rödel pers. comm. July 2016).
