Five specimens of this tiny vespertilionid were captured at Simandou, two at FC and three at WSV. One female from FC carried an embryo of 14 mm crown-rump length. In the consensus topology ( Fig. 3 ) our specimens grouped with sequences labelled H. c. bellieri from Mount Nimba , Liberia , and H. eisentrauti from Côte d’Ivoire in Monadjem et al. (2013 b ) but are now labelled H. crassulus (see Appendix for cross reference). Simmons (2005) considers bellieri to be a synonym of crassulus and she limits eisentrauti to the Cameroon highlands eastwards to Somalia , Kenya and Rwanda . Fahr (2013 d ) discusses the species as Pipistrellus crassulus with specimens from seven localities in Guinea , Liberia and Côte d’Ivoire as belonging to the subspecies P. c. bellieri . We tentatively consider the entire Hypsugo clade shown in Fig. 3 as H. crassulus . Conservation status Least Concern (as Pipistrellus crassulus ). Considered “widespread and not rare” but the population trend is unknown ( IUCN, 2015 ).
