Hipposideros dyacorum Thomas 1902

Dayak Leaf-nosed Bat (Local name not available)

Specimens examined (3).—Kubah NP: TTU 108340 (GenBank EU521620 ); Mt. Penrisen: TTU 108355, TTU 108384.

Type locality.— Malaysia (Borneo), Sarawak, Baram, Mt. Mulu.

Malaysian distribution.— Recorded from Peninsular Malaysia (Perlis: Kaki Bukit; Pahang: Krau; and restricted areas near Peninsular Thailand) and Borneo (Sabah: Mt. Mulu, Tawau Hill; Sarawak: Bako NP, Bukit Kana, Fairy Cave, Jambusan cave , Kubah NP, Lambir NP, Mt. Hose , and Similajau NP). The specimens from Mt. Penrisen represent a new geographic record.

Remarks.— Bicolor species group (Corbet and Hill 1992). All individuals were collected using harp traps set across small forest trails. Hipposideros dyacorum is distinguished from similar species H. ater , H. cineraceus , and H. bicolor by their internarial septum, which is expanded in the middle ( Philips 1967; Payne et al. 1985). Despite the overlap in size with other similar species noted above, this species has the shortest tail (19-24 mm; Payne et al. 1985).
