Myotis montivagus

French: Murin de montagne / German: Burma-Bartfledermaus / Spanish: Ratonero bigotudo de Birmania

Other common names: Burmese Whiskered Bat, Large Brown Myotis

Taxonomy. Vespertilio montivagus Dobson, 1874,

“Hotha, Yunan [= Yunnan],” China.

Subgenus Myotis; montivagus species group. Morphometric studies recently split M. montivagus into M. borneoensis, M. federatus, M. montivagus, and M. peyton. Specimens now included under recently described species M. indochinensis were also originallyidentified as M. montivagus . There are no genetic data available for “true” M. montivagus, and its relationship to otherspecies of Myotis is uncertain. Monotypic.

Distribution. S China (Yunnan), N Myanmar, and NE India (Mizoram).

Descriptive notes. Forearm 39-2-41- 5 mm. There are no other measurements available. Fur is long and dense. Dorsal pelage is dark brown, with hairs having blackish brown bases and paler chocolate-brown tips; venteris similar but slightly paler, with slightly paler hair tips. Ears are relatively short and narrow and taper toward rounded tips; tragusis long and narrow, with straight posterior margin. Wing attaches to base of outer toe. Skull has distinctly domed braincase; frontal depression is well developed; sagittal and lambdoidal crests are weakly developed; anteorbital bridge is wide; basal area of P? is one-third that of P* P? is relatively well developed and barely displaced from tooth row; and P,is developed and in tooth row.

Habitat. Hill and open forests at elevations of 500-1500 m.

Food and Feeding. No information.

Breeding. No information.

Activity patterns. No information.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Least Concern on The IUCN Red List. Recent taxonomic changes have substantially reduced distribution of the Burmese Whiskered Myotis, and its conservationsstatus is in need of revision. It is currently known from relatively few specimens over a relatively wide area, but virtually nothing is known aboutits ecology and threats.
