Taxonomy. Myotis montivagus borneoensis Hill & Francis, 1984 View in CoL ,

Sepilok, Sabah, Borneo.

Subgenus Myotis ; montivagus species group. Based on morphological and morphometric differences, M. borneoensis was separated from M. montivagus in 2013. Monotypic.

Distribution. N Borneo and scattered localities in Sabah, Kalimantan, and Sarawak. Recently, a medium-large brown Myotis (tentatively assigned to this species) was collected in Bukit Barisan Selatan National Park, S Sumatra, but this needs to be confirmed by genetic analyses. View Figure

Descriptive notes. Tail 41-47 mm,ear 15-1-16- 1 mm, hindfoot 8-9 mm, forearm 42-1— 44- 8 mm; weight 9-135 g. Furis rather long and dense. Upperparts have dark blackish brown hair bases, with dark brown tips. Underparts have similar blackish brown hair bases and buffy brown tips. Ears long and narrow, with long tragusthat reaches ¢.50% of ear length and bendsslightly forward. Wings are attached at base offirst toe. Skull is broad and not especially elongated, braincase is broad, interorbital region is wide, and zygomata are widely flared. Depression between rostrum and braincase is rather shallow. Sagittal and lambdoid crests are well developed; anteorbital bridge is wide. Basal dimension of P? is one-third that of P*. P? very small and completely displaced from tooth row so that P? and P* are usually in tight contact. P, is intruded from tooth row and not visible laterally; P, and P, are not in contact. Condylo-canine lengths are 15-4-16- 1 mm; maxillary wor rows are 6-7-7- 1 mm.

Habitat. Alongside streamsin tall forests and plantations.

Food and Feeding. No information.

Breeding. No information.

Activity patterns. The Bornean Whiskered Myotis is nocturnal.

Movements, Home range and Social organization. In a survey of small mammals in Bukit Sarang, Bintulu division, Sarawak, the Bornean Whiskered Myotis (under montivagus ) was captured syntopically with other four Myotis species—Horsfield’s Myotis ( M. cf. ater ), Gomantong Myotis ( M. gomantongensis ), and M. sp. undescribed. Bukit Sarang is a 700-m long and 80-m high limestone outcrop, surrounded by freshwater swamp forest inundated to a depth of 0-5- 1 m several times per year. In East Kalimantan, it collected in a cave in karst area.

Status and Conservation. Classified as Data Deficient on The IUCN Red List. The Bornean Whiskered Myotis is known from only a few specimens, and little is known aboutits distribution, abundance, ecology, or conservation threats.
