Taxonomy. Coelops robinsoni Bonhote, 1908 , “Gunong [= Mount] Tahan at 500 ft. [= 152 m], Pahang,” Peninsular Malaysia .

Descriptive notes. Head-body 32-34 mm, ear 12-14 mm, forearm 34—37 mm; weight 3-5— 5 g. The Malayan Tailless Leaf-nosed Bat is similar to the East Asian Tailless Leafnosed Bat ( C. frithii ), but smaller. Anterior leaf is round and wide, with deep median emargination dividing anterior leaf into two lobes. Supplementary lappets under anterior leaf are well developed, wide and rounded, and project forward covering muzzle. Pelage is long and soft, brown to dark brown on dorsal side, and brown or slightly gray on ventral side. As in the East Asian Tailless Leaf-nosed Bat, tail and interfemoral membrane are poorly developed. Skull is small with bulbous braincase. Rostral part is abruptly elevated. Upper tooth rows are almost parallel.

Habitat. Primary and secondary forest

Food and Feeding. The Malayan Tailless Leaf-nosed Bat forages in forest understory.

Breeding. No information.

Activity patterns. The Malayan Tailless Leaf-nosed Bat roosts in caves or hollows of large trees.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Vulnerable on The IUCN Red List. The Malayan Tailless Leaf-nosed Bat is rather rare and poorly known. The species is probably affected by deforestation in many parts of its range due to logging, expanding agriculture, and plantations and fire. Population is currently declining due to widescale deforestation within its range.
