Fifteen individuals of this vespertilionid were captured in lowland closed evergreen forest at FC in the canopy net over a creek. This species was not captured during the 2002 RAP (Fahr and Ebigbo, 2004), but the 2003 RAP reported it from “gallery forest of the Kpogo River” at Mount Béro ( Fahr et al. , 2006: 172 ), and these authors also mentioned unpublished museum records from Ziéla, Mount Nimba, and one specimen from Sérédou, Ziama as being the first records from Guinea . Monadjem and Fahr (2007) also mention three specimens in the Smithsonian Institution ( USNM ) from Gola Forest in Liberia . Most West African records appear to be from the closed evergreen forest with some records along the semi-evergreen forest as far north as Sakpa ( 8°52’N , 2°21’W ) in Ghana ( Schmidt et al. , 2008 ). This species is known to roost in crevices under tree bark as well as in roofs of houses ( Fahr, 2013 c ). Our 15 captures from FC point to a substantial roost somewhere upstream towards the Foko Ridge. According to Fahr (2013 c ) these specimens belong to the subspecies M. m. moloneyi . Conservation status Least Concern. Considered widespread and not rare but the population trend is unknown ( IUCN, 2015 ).
