COMMON NAME. — Noack’s Roundleaf Bat. MATERIAL EXAMINED. — Apesokubi • 1 ♂ ; SMF 92132 • 1 ♀ ; SMF 89671. Agumatsa (Wli Waterfall) • 1 ♂ ; SMF 89672 • 2 ♀ ; ZTNHC 951 , SMF 92131. Shiare Schoolyard • 1 ♂ ; SMF 92133 . REMARK Previous specimens from Ghana-Togo Highlands were from Breniasi, Worawora and Jasikan (AMNH; BMNH; Grubb 1971 ) and from Ahoué-houé, Agou, Aledjo, Fazao, Misahohé and Palimé in Togo ( De Vree et al. 1969 , 1970 ; Robbins 1980 ). We tentatively label these bats Hipposideros cf. ruber as at least three different lineages of bats affiliated with H. ruber sensu strictu from East Africa occur in Ghana , lineages B1, and D2 ( Vallo et al. 2008 , 2011 ), or what Monadjem et al. (2013) called lineage E2, or possibly lineage B1 also reaching into the Dahomey Gap ( Benin ) since our specimens are all from east of the Volta River. The distribution of specimens from West Africa weakens the assumption that H. cf ruber is a forest species.. In Côte d’Ivoire Fahr (1996) made 70 captures of H. cf. ruber , 69.2% of which were in the moist forest zone, 15.4% in forest savanna mosaic and 15.4% in savanna formations. CONSERVATION STATUS. — Listed as “Least Concern” on the IUCN Red List, Hipposideros cf. ruber appears to be still relatively common as our findings from three localities indicate.
