COMMON NAME. — Cyclops Roundleaf Bat. MATERIAL EXAMINED. — Shiare • 1 ♂ ; SMF 92134; 24.VIII.2011 ; over a small creek in a side valley of the Sabu Creek valley of Shiare . REMARK The closest previous localities from the Volta Region are from Akaniem, Breniasi and Odomi Jongo in Ghana ( Grubb 1971 ; USNM) and from Bismarckburg, Ezimé and Odjolo in Togo ( Matschie 1893a ; De Vree et al. 1969 ; Robbins 1980 ).We follow Foley et al. (2017) in the use of the name Doryrhina Peters, 1871 instead of Hipposideros Gray, 1831 . Doryrhina cyclops seems to be most often associated with rainforest, which was also recently shown at Liberian Mount Nimba ( Monadjem et al. 2016 ). This bat uses a perch-hunter foraging strategy and it requires large hollow trees for its day roosts. On the Accra Plains this species was found only in a traditionally protected sacred grove that was a remnant of high forest ( Decher 1997a ). In Côte d’Ivoire 70% of localites were in the area of moist forests, 10% in forestsavanna mosaic and 20% in savanna formations ( Fahr 1996 ). CONSERVATION STATUS. — Listed as “Least Concern” on the IUCN Red List, its dependence on large and hollow trees and preference for gallery forest ( Decher & Fahr 2005 ) make this a species of high conservation concern in the Ghana-Togo Highlands.
