Rhinolophus affinis Horsfield 1823

Intermediate Horseshoe Bat (Kelawar Ladam Hutan)

Specimens examined (4).—Mt. Penrisen: TTU 108353 (GenBank EU521607 ), TTU 108360, TTU 108361, TTU 108362.

Type locality.— Indonesia, Java.

Malaysian distribution.— Recorded from Peninsular Malaysia (all states) and Borneo .

Remarks.— Megaphyllus species group (Csorba et al. 2003). Rhinolophus affinis is distinguished from other similar species ( R. ferrumequinum , R. rouxi , and R. sinicus ) by the broadly rounded connecting process, as well as the tall and triangular noseleaf with a straight-sided lancet (Csorba et al. 2003; Francis 2008). All of our specimens were caught using harp traps along a forest trail. Coloration for this cave dwelling species ranges from bright orange to brown. Bright orange facial color on the rostrum was thought to be a diagnostic character for this species but after examination of several other specimens with similar noseleaf characters and measurements, we concluded that the orange pelage represented intraspecific variation. Approximately 4% in cyt- b genetic distance was observed between Bornean individuals from this study and a single individual from Thailand (TK 2116).
