|Taxonomic Notes:||This species is part of the Hyperolius tuberculatus Group within the H. viridiflavus complex (Schiøtz 1999).|
|Red List Category & Criteria:||Endangered B1ab(iii) ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|

Listed as Endangered because its extent of occurrence (EOO) is 261 km2, it is known from a single threat-defined location, and there is ongoing decline in the extent and quality of its habitat.
|Previously published Red List assessments:|
|Range Description:||This species is known from the lowlands on the southeastern foot of Mount Nimba in Côte d’Ivoire, where it was originally described. It was also found in Danané (M.-O. Rödel and N.G. Kouame pers. comm. June 2012), where it is probably known from less than 10 km2. It might also be found in Guinea and Liberia, however numerous surveys have been done in Guinea but the species has not yet been found there (M.-O. Rödel pers. comm. June 2012). Similarly, researchers searched for it in Liberia and were not able to detect it there (J. Penner pers. comm. June 2012). It is found around 300 m Asl. It is known from one threat-defined location and its EOO is 261 km2.|

|Population:||It was once common and is now rare at all known sites; the most recent record is from Danipleu village of the Danané region in 2010 (N.G. Kouame pers. comm. May 2012). It was not recorded from its type locality of Nimba over five separate surveys during different seasons by Joseph Doumbia between 2008–2010 (L. Sandberger and M.-O. Rödel pers. comm. July 2016). However, it was recorded at the type locality during a separate survey in 2010 (N.G. Kouame unpubl. data). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species lives in clearings in lowland forest, where it calls at the edge of large swamps. It presumably breeds in swamps.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||
There are no records of this species being utilized.
|Major Threat(s):||The main threat to this species is the establishment of rice fields and plantations. The species might be able to support some extent of habitat degradation and might actually profit from change to rice fields. However, the extent to which the species can adapt to the opening up of its habitat is unknown. Logging and construction for human settlement also occurs in the forest near its habitat and might therefore be a potential threat (M.-O. Rödel and N.G. Kouame pers. comm. June 2012).|
This species is not known from any protected areas.
Habitat protection is required at sites where this species is known to occur.
More information is needed on this species' distribution, population status, natural history, and threats (M.-O. Rödel and N.G. Kouame pers. comm. June 2012).
