Wollaston’s Leaf-nosed Bat

Doryrhina wollastoni

French: Phyllorhine de Wollaston / German: Wollaston-Rundblattnase I Spanish: Doryrina de Wollaston

Other common names: Wollaston's Roundleaf Bat

Taxonomy. Hipposideros wollastoni Thomas, 1913 ,

“Utakwa River, S.W. New Guinea [= Papua Province, Indonesia].”

Three subspecies are recognized.

Subspecies and Distribution.

D. w. wollastoni Thomas, 1913 known only from Utakwa River, Fakfak regency, West Papua Province, Indonesia.

D. w. fasensis Flannery & Colgan, 1993 known only from North Coastal Range, N Sandaun Province, Papua New Guinea.

D. w. parnabyi Flannery & Colgan, 1993 — Central Range in Sandaun, Western, Southern Highlands, Chimbu, Gulf, and Morobe provinces, mostly reported near Tifalmin and Telefomin, Papua New Guinea.

Descriptive notes. Head-body 40-8-45-3 mm, tail 27 mm, ear 15 mm, hindfoot 7-8-1 mm, forearm 44 mm; weight 8 g. Wollaston’s Leaf-nosed Bat presents a posterior lateral leaflet extending beneath anterior leaflet onto upper lip. It has club-shaped processes in intermediate and posterior leaves. The characteristic that differentiates Wollaston’s Leaf-nosed Bat from other conspecifics is presence of supplementary structure on posterior leaf, which is of similar height to the posterior leaf. Its rostrum eminences are notably inflated. Fur coloration on dorsum is brownish, while ventral part is brownish grayish.

Habitat. Wollaston’s Leaf-nosed Bat has been reported in different habitats of both primary forest (montane Nothofagus , Nothofagaceae , forest, oak forest, and hill forest) and secondary forest. Altitudinal range is very wide (30-2440 m).

Food and Feeding. Wollaston’s Leaf-nosed Bat probably feeds on insects.

Breeding. No information, but reproduction probably occurs in caves.

Activity patterns. Wollaston’s Leaf-nosed Bat has been observed roosting in deeper and wetter caves in limestone areas. Call frequency is c.82 kHz.

Movements, Home range and Social organization. Small colonies of Wollaston’s Leafnosed Bats have been observed roosting in caves. This species often shares roosts with Telefomin Leaf-nosed Bats ( D. corynophyllus ).

Status and Conservation. Classified as Least Concern on The IUCN Red List (as Hipposideros wollastoni ). Current population size and trends are unknown, but population is probably not greatly fragmented. Loss or disturbance of cave roosts might be one of the major threats for Wollaston’s Leaf-nosed Bat, as well as foraging habitat loss and degradation. Further research is needed to study and understand the population distribution and ecology of this species.
