Previous records included in Appendix I ; the known distribution corresponds to localities 17, 19, 26, and 29 in Fig. 1 . This species is considered by Happold and Happold (2013) to be very common in some areas of Africa. FIG. 6. Bacula (dorsal view [left] and lateral view [right]) of (A): Hipposideros ruber , HZM.78.40176 and (B): Triaenops afer , HZM.39.40178. Scale = 0.5 mm Description A medium-small species with a forearm length of 54.4–57.5 mm ( Table 2 ). The face is characterised by a distinctive noseleaf, which includes three vertical processes projecting from the upper part and a fourth smaller vertical process situated at the base of the middle upper process (for further details of the noseleaf morphology see Monadjem et al ., 2010 : Figure 93a and b). The second phalanx of the fourth digit is unique in possessing a transverse spicule of bone, which projects from the outer side of its base for a distance of 2.5 to 3 mm into the membrane. The skull (SL: 18.73–20.12) is narrow and elongated with a well developed rostrum. The zygomata are not outwardly flared but are very greatly expanded dorsally. In the upper dentition, the third molar (M 3 ) is not reduced, having three commissures and a well developed metacone. The baculum is short ( 1.8 mm ); it has a straight shaft with an expanded tip and bilobate base ( Fig. 6B ). Taxonomic notes The taxon afer is variably treated as a subspecies of T. persicus ( Simmons, 2005 ; Monadjem et al ., 2010 ) or as a distinct species ( Happold and Happold, 2013 ). Benda and Vallo (2009) considered it to be a discrete species confined to Africa based on differences in the skull, baculum and Cytochrome b . Specimens previously collected from southern Congo were described as a new subspecies majusculus Aellen and Brosset, 1968 on the basis of their large size; Cotterill (2001) suggested that majusculus may prove to be a distinct species but this is contrary to Benda and Vallo (2009) , who considered even its subspecific status to be questionable. The three specimens from Lekoumou are referred to T. afer majusculus being comparable in size to specimens previously collected from Congo .
