The pipistrelloid bats (genera Hypsugo, Neoromicia, and Pipistrellus) of Africa have been poorly studied, partly as a result of problems associated with species identification. This paper examines the diversity of pipistrelloid bats from Mount Nimba, a biodiversity hotspot in the Upper Guinean rainforest zone. Traditional morphometrics, the structure of the baculum, and sequences of the cytochrome oxidase subunit I (COI) gene were used to identify taxa. Species richness was exceptionally high and included at least ten taxa identifiable on molecular grounds. Of these, existing names could be assigned to six taxa. A seventh taxon was described as a species new to science, Neoromicia roseveari sp. nov., and was distinguished on molecular grounds, craniodental morphology, and baculum structure. The remaining taxa may refer to as-yet undescribed species but we lacked sufficient material to formally describe them here. The high species richness of pipistrelloid bats on Mount Nimba may be associated with the transition zone from lowland rainforest to moist savannah.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
