point; occasionally there is a slight median 
postpalatal protuberance but more usually this is a 
smooth U shape; premaxilla posteriorly terminates 
at P 3 mid point; sphenoidal/pterygoid bridge 
obscures anterior sphenorbital fissure when 
viewed from the ventral aspect; incisors weak, 
bilobed; M 1 ' 2 hypocone well developed. 
Externals 
The external characters are similar to those 
described by Andersen (1905) for Rhinolophus 
simplex. The anterior noseleaf is moderately wide 
(8.2) with an obvious anteromedian notch. The 
vertical sella is longer than the basal sella (4.0 v. 
2.3), smoothly curved at the apex and not 
noticeably constricted. Ears are moderately long 
(17.8), outer apical margin reasonably concave. 
Pelage and skin colour 
Dorsal pelage of most specimens Fuscous, which 
is colour of distal one-third of hairs, the basal part 
of which is Drab. Ventral surface pure Drab. 
Occasional specimens of both sex paler, with 
dorsal surface Russet, which is colour of distal one- 
third of hairs, the basal part of which is Cream 
Color. Ventral surface pure Fawn Color. Wing and 
ears Fuscous. 
Baculurn 
The shape of bacula among Rhinolophus simplex 
largely differs in the extent of the incision in the 
posteroventral basal margin (Figure 10, Table 8), 
which ranges from deeply incised in WAM M38252 
(Bali I). to slightly concave in WAM M30249 
(Sumba I). All these basal types occur in R. s 
simplex. 
Distribution 
Many islands in the Inner Banda Arc; Bali, Nusa 
Penida, Lombok, Sumbawa, Moyo, Sangeang, 
Komodo, Rinca, Flores, Lembata, Alor, Wetar 
islands and Sumba Island in the outer Banda Arc. 
Its ability to occupy new habitats, such as defence 
tunnels build by Japanese during the Second World 
War, suggest that it is a good colonist and that it 
probably exists on many other islands in this 
region.
