Telefomin Leaf-nosed Bat

Doryrhina corynophyllus

French: Phyllorhine deTelefomin / German: Telefomin-Rundblattnase I Spanish: Doryrina deTelefomin

Other common names: Telefomin Roundleaf Bat

Taxonomy. Hipposideros corynophyllus Hill, 1985 ,

“Inum Tem (Cave), 3 km ENE of Telefomin, West Sepik Province, Papua New Guinea, 1800 m, c. 5°10’S, 141°35’E.”

This species is monotypic.

Distribution. Known only from a small area around Tifalmin and Telefomin in Sandaun Province, W Papua New Guinea, and also collected in Tembagapura region, Papua Province, Indonesia. Even so, its echolocation calls have been recorded in other areas and it is thought that this species has a larger distribution, probably occurring throughout the Central Range ofNew Guinea.

Descriptive notes. Head—body 54-9-63 mm, tail 9—12 mm, ear 18-9—22-6 mm, hindfoot 9-5—11-9 mm, forearm 48-54-6 mm; weight 14-5— 17 g. The Telefomin Leaf-nosed Bat has an elongated rostrum and relatively long hair, which is densely distributed even on face and muzzle. Brownish colors are present on dorsum, with paler silver on ventral area. Fur is long (c.14-2 mm). Ears are relatively long, distally narrowed, and convex on anterior or medial margin of ear, without antitragal lobe. Noseleaf covers much of muzzle, with two lateral leaflets. Anterior leaf has no median emargination, intermedian leaf is elevated laterally, and posterior leaf is high. Median processes of intermediate and posterior leaves are well developed and club-shaped. Lower club is very long and tubular.

Habitat. The Telefomin Leaf-nosed Bat is found in deep limestone caves, usually located at elevations of 1600—1800 m. It also occurs in forests and in other subterranean cavities. The altitudinal range of this species is very wide, ranging from close to sea level up to 2700 m.

Food and Feeding. The Telefomin Leaf-nosed Bat probably forages in forest habitats.

Breeding. The breeding biology of the Telefomin Leaf-nosed Bat is largely unknown; it is probably similar to that ofWollaston’s Leafnosed Bat (D. woUastoni).

Activity patterns. Activity patterns of the Telefomin Leaf-nosed Bat are probably similar to those ofWollaston’s Leaf-nosed Bat.

Movements, Home range and Social organization. The Telefomin Leaf-nosed Bat may be found either solitarily or in small groups. It sometimes shares caves with Wollaston’s Leaf-nosed Bat (subspecies pamabyi) in the Telefomin area.

Status and Conservation. Classified as Least Concern on The IUCNRed List (as Hipposideros corynophyllus ). Current population trends are unknown, but population is probably not strongly fragmented. Forest loss and modification might be the major threats for the Telefomin Leaf-nosed Bat, although large areas of intact forest still remain within its range. More research is needed to study and assess the ecology and population status of this species.
