Creagh's Horseshoe Bat
   
   

Order : CHIROPTERA
Family : Rhinolophidae
Species : Rhinolophus creaghi

Forearm Length : up to 5.1 cm
Weight : up to 13.5 grams

Rhinolophus creaghi (Creagh's Horseshoe Bat) is a geographically widespread species, however it appears to be known only from areas of karst limestone where large caves may support roosts of up to one hundred thousand.

Fur colour of this small bat varies between different subspecies or populations, ranging from reddish to yellow-brown to grey-brown. The two examples shown here, from the Niah cave complex in Sarawak, where the species is described as rare (Phillipps & Phillipps, 2016), are mainly dark grey.

This species bears a conical tuft of hairs on the posterior part of the noseleaf (i.e. the upper part of the noseleaf between the eyes); this is an uncommon feature in rhinolophid bats.

The most recent IUCN assessment (2018) includes the following locales for this species; Borneo (particularly Sarawak, Sabah and Sangkulirang, East Kalimantan), Palawan (Philippines), Madura Island (which lies off the northeast coast of Java, Indonesia) and Nusa Penida (which lies off Bali, Indonesia).
