Hypsugo crassulus (Thomas, 1904)

Fig. 41 A–B

* Pipistrellus crassulus Thomas, 1904: 206 .

As indicated by Fahr (2013q: 617) crassulus has been moved into various (sub)genera or “collective groups” over the past few years: Pipistrellus, P. (Vansonia), “ Attalepharca ”, Hypsugo and Nycticeinops . The currently most accepted view is that it belongs to the genus Hypsugo .

Hayman et al. (1966: 52, map 72) reported it from two localities: Bokuma (Equateur Province) and Mulolo-Kisanga (Maniema Province), and more recently it was also found at Irangi (Sud-Kivu Province). The distribution map provided by Fahr (2013q: 618) only shows a very restricted red area covering the eastern parts of the Kivu Provinces reaching towards Maniema Province. Furthermore, there are single records from Guinea, in West Africa, over Côte d’Ivoire, southern Cameroon, northwestern DRC (the Bokuma record), northern Angola, southern South Sudan, southern Uganda and southwestern Kenya. Based on climatic data, the SDM map covers this area, but also suggests it might occur in Equatorial Guinea, Gabon, southern Congo, and southwestern and southeastern DRC.
