This species is found in the Upper Guinea Forest Block and ranges from Sierra Leone, through Liberia and southern Guinea, to southcentral Côte d’Ivoire. It is found in Pic de Fon Classified Forest in Guinea. It is has been collected at 600 m and at 1,000 to 1,600 m asl (N.G. Kouamé pers. comm. June 2012).
Using the range as a proxy, the extent of occurrence (EOO) is estimated to be 204,926 km2.
Is it possible to get an estimate of: the AOO (with reasoning) and the number of threat-defined locations? EJM
It is arboreal, and usually confined to primary rainforest where it is generally found by streams, though it has also been recorded in secondary forest (N.G. Kouamé pers. comm. June 2012). It breeds exclusively in flowing water, laying its eggs on leaves above water into which the larvae fall and develop.
It is a rare species that is difficult to see; only the call of the male can indicate its presence (N.G. Kouamé pers. comm. June 2012). It was last recorded in 2011 (N.G. Kouamé pers. comm. May 2012). Due to major threats, such as habitat destruction due to agricultural expansion, it is believed to be declining.
It is threatened by ongoing habitat loss, which is caused by logging for wood that is often exported, and expanding agriculture (mainly cacao and coffee plantations) (N.G. Kouamé pers. comm. June 2012).
It occurs in many protected areas, including Taï National Park in Côte d’Ivoire and Sapo National Park in Liberia. More information is needed on this species' distribution, population status, natural history, and threats.
Listed as Near Threatened because, although this species is still relatively widely distributed, it depends on streams in undisturbed forest habitat, so its Area of Occupancy is probably not much greater than 2,000 km2. Furthermore, the extent and quality of its habitat is declining, thus making the species close to qualifying for Vulnerable.
According to our records this species may not have been formally reassessed. The current assessment relies on an estimate of the AOO; it would make this a more robust assessment if this could be confirmed with reasoning. To qualify for the VU category, an estimate of the number of threat-defined locations or evidence that the population is severely fragmented (according to the Red List guidelines) is needed. EJM
