The Malayan Tailless Leaf-nosed Bat (Coelops robinsoni) is a species of bat

Bat

Bats are mammals of the order Chiroptera "hand" and pteron "wing") whose forelimbs form webbed wings, making them the only mammals naturally capable of true and sustained flight. By contrast, other mammals said to fly, such as flying squirrels, gliding possums, and colugos, glide rather than fly,...

 in the family Hipposideridae. It is a very small bat which has long and soft fur. The fur coloration is brown to blackish on the dorsal surface and ashy on the ventral surface. It can be distinguished from the other roundleaf bats by its small size and the absence of the tail. It is listed as vulnerable by the IUCN (Heaney, 2008)

Biology

In Thailand, this species is known to form small colonies inhabiting caves and is considered a rare species (Lekagul & McNeely, 1977). In Peninsular Malaysia, the species has been recorded roosting in a cave and in the hollow buttress of a tree and shares its roosting site with Hipposideros ridleyi (Kingston et al. 2006; Francis, 2008). In Philippines, this species was previously known as C. hirsutus and recorded only from Mindoro Island (Nowak, 1994; Wilson & Reeder, 2005). However, Hill (1972) suggested that C. hirsutus was a conspecific species of C. robinsoni. Until now, the ecology and habitat preference is still poorly known, due mainly to the species being difficult to catch. Throughout its distribution it is not known whether the small number of specimens is due to low population numbers or it has a high level of trap and net avoidance due to a combination of flight pattern and sensitive echolocation.

Distributions

In Sarawak, only recorded from Eastern part of Sarawak(Bintulu, Niah National Park and Mulu National Park)(Mohd Ridwan et al. 2010). The distribution of this bat is restricted to the Southeast Asian region from Peninsular Thailand, Peninsular Malaysia and Borneo and possibly to Philippines (Payne et al. 1985; Francis, 2008).
