Taxonomy. Murina walstoni Furey, Csorba & Nguyen Truong Son, 2011,
“ Cambodia, Ratanakiri Province, Veun Sai District, Veun Sai Protected Forest, 14°01'49”N, 106°45'06"E, elevation 110 m.”
Murina walstoni appears to be related to M. swilla and M. aenea based on limited genetic data. Monotypic.
Distribution. EC & WC Thailand, C & S Laos, S Vietnam (including Phu Quoc I), and SE & SW Cambodia.
Descriptive notes. Head-body 34:8-45- 4 mm, tail 26-6-32- 5 mm, ear 11-9-14- 7 mm, hindfoot 6- 1-7 mm,forearm 28-1-34- 7 mm; weight 4-2-4- 6 g. Fursilky. Dorsal pelage is warm brown (hairs with whitish bases and grayish brown or orangish brown tips); venter is pure white (hairs white from base to tip). Dorsal pelage extends sparsely onto wings, uropatagium, thumbs, and feet. Face is sparsely haired except for long protuberant naked nostrils. Ears are short, broad, and rounded with smoothly convex anterior margins, no notch on posterior margins, and broadly rounded tips; tragus is long and narrow and tapes toward pointed tip. Wing attaches to base of claw on first toe. Skull has non-inflated rostrum and domed braincase; sagittal and lambdoidalcrests are well developed; I? is partly anterior to I%, C' is taller than P* but has smaller basal area; P? is much shorter than P* and has one-half the basal area: mesostyles of M' and M? are moderately developed; and talonids of M, and M, are larger in size than their respective trigonids.
Habitat. Various forest types from open heavily disturbed forests to pristine forests, lowland mixed deciduous forests, semi-evergreen forests, and dry forests at elevations of 100-400 m.
Food and Feeding. No information.
Breeding. A lactating Walston’s Tube-nosed Bat was caught in August in Thailand.
Activity patterns. One Walston’s Tube-nosed Bat was collected roosting under a dead banana leaf in Thailand. Calls have steep FM sweeps. In Kamphaeng Phet, Thailand, recordings of one male had start frequencies of 140-153 kHz, end frequencies of 52— 65 kHz, peak frequencies of 117-2-128 kHz, and durations of 1-7-2-4 milliseconds. Similar frequencies were recorded from one female in Loei, Thailand, with start frequencies of 145-149 kHz, end frequencies of 46-49 kHz, peak frequencies of 108-8— 113-7 kHz, and durations of 3-1-4 milliseconds.
Movements, Home range and Social organization. Walston’s Tube-nosed Bat reportedly roosts alone.
Status and Conservation. Not assessed on The IUCN Red List. Walston’s Tube-nosed Bat appears to be relatively widespread, but very little is known aboutits ecology and threats. It is unlikely to be at risk because it occurs in heavily disturbed habitats.
