Mount Cameroon is a priority area for global biodiversity conservation, considering its high species richness and endemism across many taxa. As of yet, its Chiroptera fauna is still poorly known. Thus this paper aims to provide an updated checklist of the Chiroptera fauna of Mount Cameroon based on our own field data, previously published data and data from museum collections. Details on published references and conservation statuses are also provided for each species. During our field surveys (2016-2018), 613 individuals and 21 species were recorded. Among them three species are new to the area: Mops (Xiphonycteris) nanulus J. A. Allen, 1917, Mops (Xiphonycteris) thersites (Thomas, 1903) and Glauconycteris egeria Thomas, 1913. These new records bring the number of known bat species in the Mount Cameroon area to 38, belonging to seven families. This includes Pteropodidae Gray, 1821 (eleven species), Hipposideridae Gray, 1821 (six species), Rhinolophidae Gray, 1825 (three species), Miniopteridae Dobson, 1875 (three species), Vespertilionidae Gray, 1821 (seven species), Nycteridae Van der Hoeven, 1855 (five species) and Molossidae Gervais, 1856 (three species). We also observe that 23.7% of bats in the area are frugivorous (nine species), 71.1% are insectivorous (27 species) and 5.3% are nectarivorous (two species). Moreover, because of the increasing rate of deforestation in the area caused by slash-and-burn shifting cultivation and expansion of agro-industrial plantations, knowledge of the regional chiropteran fauna is imperative, especially as this information can provide a base for the development of future management and conservation strategies.
