Hill’s Leaf-nosed Bat

Doryrhina edwardshilli

French: Phyllorhine d'Edwards Hill / German: Hill-Rundblattnase I Spanish: Doryrina de Edwards Hill

Other common names: Hill's Roundleaf Bat

Taxonomy. Hipposideros edwardshilli Flannery & Colgan, 1993 ,

“Imonda Station (3°20’S 141°10’E), Bewani Mountains, Papua New Guinea at an altitude of 240 m.”

This species is monotypic.

Distribution. New Guinea, known only from three zones of the Bewani Mts, North Coastal Range, Sandaun Province.

Descriptive notes. Head-body 50-6 mm, tail 11-1-15 mm, ear 19-3-21-3 mm, hindfoot 8-2 mm, forearm 49-6-51 mm; weight 11 g. Hill’s Leaf-nosed Bat is similar to the Telefomin Leaf-nosed Bat (D. corynophyUus), but with darkish brown or reddish fur on dorsum, and more cinnamon color on ventral area; subadults can present grayish coloration. Fur is markedly shorter than on the Telefomin Leaf-nosed Bat: c.8-7 mm long on mid-back. Noseleaf differs in lower club being less pronounced, shorter and laterally flattened, as compared with that of the Telefomin Leaf-nosed Bat.

Habitat. Hill’s Leaf-nosed Bat is a cave-roosting species reported in low hills. It can be present in forest and also in more modified and artificial environments such as gardens or rural village areas, although it always needs cave roosts nearby. It has only been reported at altitudes of c.200-300 m, which accounts for its restricted range.

Food and Feeding. Insects constitute its main food. Hill’s Leaf-nosed Bat has been reported foraging in forests, rural village areas, and gardens.

Breeding. No information.

Activity patterns. No information.

Movements, Home range and Social organization. Unlike the Telefomin Leaf-nosed Bat, Hill’s Leaf-nosed Bat has not been found sharing caves with Wollaston’s Leafnosed Bat ( D. wollastoni ).

Status and Conservation. Classified as Vulnerable on The IUCN Red List (as Hipposideros edwardshiUi ). Population size and trends of Hill’s Leaf-nosed Bat remain unknown. Main threats probably include habitat degradation and transformation of native forest to agricultural lands around Bewani Mountains. In addition, the fact that the North Coastal Range is not limestone might reduce the roost availability, restricting the potential range (100—2000 km 2) even more. More research on this species is needed to assess its population status accurately and to discover details of its ecology.
