During this survey, it was recorded roosting in mine adits above 1,400 m on the Guinean side of the mountain, at the same locality as previously recorded by Brosset (1985) . The taxon alticolus may represent a distinct species ( Csorba et al ., 2003 ), and was in fact recognized as such by Rosevear (1965). The records from Guinean Nimba and Wonegizi Mts in Liberia are isolated by about 2,000 km from the nearest records in Nigeria and Cameroon ( Happold, 1987 ), which themselves are further isolated by thousands of kilometres from populations in East and Southern Africa.
