Pipistrellus nanulus Thomas, 1904: 198; Efulen, Cameroons (= Cameroon).
New material
HZM.1.40189, ♂, 4 August, 2012, Forest Trails, Lekoumou, 2°45.767’S, 13°36.365’E. This is the first authenticated record for Congo (Appendix I). Its relative abundance in Africa is not known (Happold and Happold, 2013).
Description
A small, nondescript, species with a very short forearm length (26.1 mm) (Table 2). The interfemoral and wing membranes are uniformly dark; the pelage is also uniformly dark on the back and buff-brown on the belly. The muzzle is thick and broadly rounded. In each ear, the tragus has a very slightly concave anterior border, a rounded tip, a smoothly rounded posterior border and a well developed basal lobule (Fig. 8G). The skull is short (GTL= 11.99 mm) (Table 3), the rostrum is short and the braincase is low (Fig. 10C). The first upper incisor (I 2) is strongly bicuspid; the second (I 3) is unicuspid but with a well developed cingulum, it attains two-thirds the height of the secondary cusp of I 2 (Fig. 10C). The small, first upper premolar (P 2) is comparatively well developed and is slightly displaced internally; the canine and second premolar (P 4) are not in contact (Fig. 10C). The lower canine has a small but well-developed cusp on the anterior cingulum. The first lower premolar (P 2) is about equal in crown area and two-thirds the height of the second (P 4) (Fig. 10C). The baculum is long, with a bifid tip, a straight shaft and two, relatively ill-defined, basal lobules (Fig. 11D); this compares well with the baculum of the holotype of nanulus illustrated in Hill and Harrison (1987, Figure 7f).
Taxonomic notes
