Hipposideros cf. ruber (lineage C1)

This species belongs to the caffer / ruber complex and has yet to be named, but has been placed in the lineage C1 (Vallo et al., 2008). Morphologically, it is indistinguishable from the next species, but differs in echolocation call and on molecular grounds (Monadjem et al., 2013 b). At present this species is only known from the Liberian side of Mt Nimba and further molecular studies on the Guinean side are needed to confirm its presence there. Species of the caffer / ruber complex have previously been recorded widely in Guinean and Liberian Nimba (Aellen, 1963 [as H. caffer guineensis]; Verschuren, 1977; Wolton et al., 1982; Brosset, 1985; Denys et al., 2013), but it is not known to which lineage these specimens belong.
