It was recorded from both Guinean and Liberian Nimba during this survey, at higher altitudes above 900 m . This species closely resembles R. landeri (specimens of both species at Mt Nimba had pointed connecting processes and the anterior premolar within the toothrow) but was distinguished from it by its larger size (forearm and greatest skull lengths were 44.3, 46.7 mm and 19.3, 21.2 mm for two individuals DM 13214 and DM 14088). Rhinolophus alcyone is typically far larger in size.
