Scientific Name
Myotis nimbaensis
Global Conservation Status (IUCN)
Critically Endangered

Data Sheet

IUCN Conservation Status: Critically Endangered 

United States Conservation Status: n/a 

Diet: Insectivore 

Apart from being an insectivore the diet of this species is unknown. Based on similar species the Nimba myotis is likely to be an aerial netter (also called aerial hawkers), gleaners, and trawlers. Myotis tricolor in South Africa feeds primarily on hard-bodied prey with coleopterans making up the greatest proportion of the diet, followed by hemipterans (Stoffberg and Jacobs, 2004). 

Fun Fact: The Nimba myotis was unknown to science until it was captured in 2018 using mining adits on the Nimba mountains, Guinea. 

Appearance: Compared to other Myotis species of bat found in Africa, this is a relatively large species (15 – 17g) with females apparently somewhat larger than males. They have bright orange fur covering their bats, which is paler on their belly.  

Habitat: Only two bats have been discovered to date. Both individuals were found in subterranean features (mining adits) surrounded by high-altitude grassland, montane savanna, and gallery forest habitats of the Nimba Mountains around 1400 m in elevation.  

Conservation Concerns: This species is currently listed as ‘Critically Endangered’ on the IUCN Red List as the population has only been recorded from a one location. They face multiple threats; the underground sites they are using are collapsing, there is the threat of renewed mining in the area, and an increase in wild fires are decreasing the quality of surrounding habitat.
