“Ban Khankeo (formerly known as Ban Phahôm), along the upper Nam Hinboun, Bolikhamsai Province, Khammouan Limestone NBCA, Lao PDR, 17°58’N, 104°49’E.”

Hipposideros scutinares is in the pratti species group. Monotypic.

Distribution. Endemic to C Laos and adjacent C Vietnam.

Descriptive notes. Tail 50-4—54-3 mm, ear 27*6-29* 4 mm, hindfoot 15—18* 8 mm, forearm 77*9-82* 7 mm; weight 42 g. Ears of the Shield-nosed Leaf-nosed Bat are well developed, haired in one-third of their length and with a slightly concave shape below tip. On dorsum, fur is brown or orange-reddish at base, followed by a brown-yellowish color in central portion of each hair, with brown tips; in ventral part, fur is brown-reddish at base with brown-yellow tips. In middle of anterior noseleaf there is a small emargination. There are two supplementary lateral leaflets. Lateral borders of anterior and posterior leaves are joined. To rear of posterior noseleaf there is a protuberance on each side of frontal sac; shape of this protuberance reminds supplementary lateral leaflet and is more noticeable in males. Rostrum eminences are slighdy inflated.

Habitat. The Shield-nosed Leaf-nosed Bat has been observed roosting in caves in limestone areas, karst, and cliffs. It has also been reported in evergreen forest, and deciduous forest with bushes and bamboo. It occurs in primary forests as well as in more degraded habitats including agricultural land, such as ricefields, reaching altitudes of 160 m.

Food and Feeding. The Shield-nosed Leaf-nosed Bat is thought to forage in primary forests, as well as agricultural lands and other disturbed habitats. Its diet is probably based on insects.

Breeding. Breeding colonies are located only in caves. No other information is known as yet about the breeding biology of the Shield-nosed Leaf-nosed Bat.

Activity patterns. The Shield-nosed Leaf-nosed Bat is a cave-dwelling species. Echolocation call frequency of this species is c.63*6 kHz.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Vulnerable on The IUCNRed List due to its small geographic range. Reported only in eight areas, six in Laos and two from adjacent Vietnam. The population of the Shield-nosed Leaf-nosed Bat is probably decreasing, its population size being estimated at 10,000 individuals or less. Habitat loss could be the most important threat to this species.
