Rhinolophus pearsonii pearsonii Horsfield, 1851
This is a large-sized horseshoe bat characterized by a single mental groove. The horseshoe is large covering the muzzle and the connecting process is broadly rounded. The base of the sella is wide. The noseleaf, although similar to that of R. luctus and R. beddomei, has no basal lappets on either side of the sella. The forearm length averages 53.1 mm (50.0 – 54.8 mm). The pelage is long, soft and woolly. The dorsal and the ventral surfaces are mid chestnut brown in colour and the ventral surface is slightly paler. Hairs are present on the upper surface and posterior border of the interfemoral membrane.
This species can be separated from R. yunanensis, R. beddomei and R. luctus based on its smaller size (FA: 50.0 – 54.8 mm vs FA: 54.2 – 59.5 mm, 54.9 – 64.3 mm and 70.0 – 80.5 mm).
An uncommon species of South Asia found in mountainous regions in varying altitudes ranging between 610 – 3384 m asl. Diurnal roosts include caves, old dilapidated buildings and sometimes bunkers.
