Listed as Data Deficient, because, whilst it appears to have a large extent of occurrence (EOO) of approximately 116,755 km², very little is known about its natural history, threats and conservation status.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This Central African species has been recorded from 12 collection localities with eight in southern Cameroon (south of the Sanaga River), two in Equatorial Guinea (Rio Muni and Benito River), and Gabon (Belinga), and two in the Democratic Republic of Congo (Inkongo and Masako) (Holden and Levine 2009). Additional survey work will probably reveal the distribution of this species to be more continuous.

Population [top]

Population:It is known only from 22 museum specimens and is described as uncommon (Holden and Levine 2009).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is associated with lowland tropical moist forest. Few additional details are available concerning the species natural history.

Threats [top]

Major Threat(s): The threats to this species are not known. It is not known if the species can persist in modified or degraded habitats. It has been estimated that around 80% of the original forest area in West Africa is now an agriculture-forest mosaic caused primarily by agricultural expansion, sometimes facilitated by other human activities such as wood extraction (Norris et al. 2010).

Conservation Actions [top]

Conservation Actions: It is possibly present in several protected areas. Additional studies are needed into the taxonomy, distribution, abundance, general ecology and threats to this little-known species.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
