Shield-faced Leaf-nosed Bat

Hipposideros lylei

French: Phyllorhine de Lyle I German: Lyle-Rundblattnase I Spanish: Hiposidérido de Lyle

Other common names: Shield-faced Roundleaf Bat

Taxonomy. Hipposideros lylei Thomas, 1913 ,

“Chiengdao Cave, 50 miles [= 80 km] north of Chiengmai [= Chiang Mai, northern Thailand]. Alt. 350 m.”

Hipposideros lylei is in the pratti species group (3 species). Monotypic.

Distribution. S China (Yunnan), E & S Myanmar, W & S Thailand, N Vietnam, and Malay Peninsula; a record from Laos has not been confirmed but the species is very likely to occur there.

Descriptive notes. Head-body 72-95 mm, tail 48-55 mm, ear 30 mm, hindfoot 16-21 mm, forearm 73—84 mm. The Shield-faced Leaf-nosed Bat has enlarged fleshy lobes projecting behind posterior noseleaf. Tip is terminated into two projections around forehead. Noseleaf is very large in adult males but much smaller in females and immatures. There are two lateral leaflets on each cheek. Ears are large with triangular tip, and without antitragus. Pelage is uniformly pale gray to fight brown, or sometimes paler on ventral side. In skull, sagittal crest and zygomata are moderately developed. P2 is small and usually slightly extruded from tooth row.

Habitat. Primary forest as well as some disturbed and fragmented zones in limestone areas.

Food and Feeding. The Shield-faced Leaf-nosed Bat feeds on insects in the understory of primary and disturbed lowland forest

Breeding. The Shield-faced Leaf-nosed Bat has been found pregnant in February and March, and young are found attached to females in late March-April.

Activity patterns. The Shield-faced Leaf-nosed Bat roosts in limestone caves. Echolocation is a CF/FM type, with a call frequency of the F segment of 70-75 kHz.

Movements, Home range and Social organization. The Shield-faced Leaf-nosed Bat is usually found sharing caves and mixing in the same large colonies with other large Hipposideros , such as Great Himalayan Leaf-nosed Bats (77. armiger ), Diadem Leaf-nosed Bats (77. diadema ), and Horsfield’s Leaf-nosed Bats (77. laruatus ), but it is never abundant

Status and Conservation. Classified as Least Concern on The IUCNRed List. The Shieldfaced Leaf-nosed Bat is recorded in several protected areas throughout its range. However, like other South-east Asian cave-dwelling bats, it might be at risk because of human disturbance or limestone mining, and quarrying.
