New material ZFMK 2008.0295 , , FC, 8 March 2008 ; ZFMK 2008.0296 , , TO , 14 March 2008 ; ZFMK 2009 . 0032, , CMR, 18 December 2008 ; ZFMK 2009 . 0029. , WSV, 12 December 2008 . We captured seven slightly larger individuals than H. crassulus (discussed above) and assigned them to the genus Hypsugo : two were captured in the canopy net over the creeks at FC, one in a forest net at TO , three over the creek in the WSV and one over the creek in gallery forest at CMR. They ranged in body mass from 7 to 14 g . One female ( ZFMK 2008.0295) carried a single embryo of 17 mm crown-rump length. In the molecular analysis ( Fig. 3 ), our four specimens grouped with a specimen from Mount Nimba ( DM 13225) tentatively labelled Neoromicia sp. 1 ( Monadjem et al. , 2013 b ) forming a sister group to H. crassulus . These specimens also have the “much reduced, small” upper anterior premolar described by Hill and Harrison (1987: 244) as a characteristic of the subgenus Hypsugo . Thus, we tentatively assign them to an unidentified species of Hypsugo . Conservation status The conservation status of this species has not yet been evaluated ( IUCN, 2015 ).
