New material

HZM.1.40189 , ♂, 4 August, 2012, Forest Trails, Lekoumou , 2°45.767’S, 13°36.365’E GoogleMaps . This is the first authenticated record for Congo ( Appendix I View APPENDIX ). 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 View TABLE ). 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 View FIG ). The skull is short (GTL= 11.99 mm) ( Table 3 View TABLE ), the rostrum is short and the braincase is low ( Fig. 10C View FIG ). 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 View FIG ). 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 View FIG ). 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 View FIG ). The baculum is long, with a bifid tip, a straight shaft and two, relatively ill-defined, basal lobules ( Fig. 11D View FIG ); this compares well with the baculum of the holotype of nanulus illustrated in Hill and Harrison (1987, Figure 7f View FIG ).
