Shield-faced Roundleaf Bat (Hipposideros lylei)
Brownish grey in colour, with buffy underparts, the nose leaf is brownish pink, the ears and wings are pale brown. The ears are broad and rectangular, with no antitragus. This is a species dimorphic species, with adult males having enormous wing like fleshy expansion terminated into 2 projections around the frontal sac; females and immature have a similar structure, but much smaller and very difficult to see behind the posterior leaf. The lateral margins of the anterior and posterior leaves are continuous. The skull has a low sagittal crest and moderate zygomata.
This species is found in Yunnan, China (Smith et al.
2008), extending to Myanmar, Thailand, Malaysia, and Vietnam. It can be
expected in northern Lao PDR, but this has not been confirmed.
China; Malaysia; Myanmar; Thailand; Vietnam
This species tends to have small populations at each location.
In Thailand, populations are typically comprised of less than a hundred
individuals. The species is usually caught as individuals (S. Bumrungsri and P.
Bates pers. comm.).
Population Trend: Decreasing
Habitat and Ecology:
It is associated with caves in limestone areas, the
species can occur in disturbed and fragmented areas, including agricultural
areas (S. Bumrungsri and P. Bates pers. comm.).
There are no major threats to this species, although
cave disturbance affects the species throughout its range. In addition it is
hunted at least in Thailand (S. Bumrungsri pers. comm.).
It is known to occur in some protected areas.
