Taxonomy. Kerivoula kachinensis Bates et al., 2004,

“Namdee Forest, Bhamo Township, Kachin State, Myanmar, 24°34.203'N, 97°07.501'E. ”

See K. hardwickii . Kerivoula kachinensis appears to be close to K. depressa and K. hardwickii or K. furva in some analyses. Monotypic.

Distribution. N Myanmar, N Thailand, Laos, N & C Vietnam, and SE Cambodia.

Descriptive notes. Head-body 44.753.6 mm, tail 52: 3-61 mm, ear 11: 9-16 mm, hindfoot 8:6-9- 7 mm, forearm 40-1— 43- 2 mm; weight 6-3-9- 5 g. Fur is long and dense. Dorsal pelage is brown (hairs with dark gray bases, gray-brown middles, and whitish brown tips); venter is a little paler. Face is covered in hair, except naked nostrils. Ears are large and naked, with convex anterior borders, rounded tips, and distinctly concave partjust below tips on posterior borders; tragus is tall and narrow, with virtually straight anterior margin and slight convexity below tip and concave posterior margin with small basal lobe. Wings are attached at base of toes, and membranes are dark grayish brown; there is no definite fringe of hairs on posterior margin of uropatagium. Fleshy callosity occurs at base of each thumb on wings that is centrally smooth and rugged near edge. Skull has distinctly flattened and broad braincase; rostrum has large V-shaped narial pit; basioccipital pits are shallow; and postorbital constriction is narrower than posterior part of rostrum. I? and I? are unicuspid and equal in crown area; M’ is reduced, missing metastyle; I, and I, are tricuspid; I, is smaller and has well-developed central cusp; and M, has reduced talonid that is ¢.70% the size of trigonid.

Habitat. Primarily evergreen and mixed deciduous forests but also deciduous dipterocarp forests near bamboo (Cambodia), transition zone between lower montane and mixed deciduous forests (Thailand), disturbed semi-evergreen and evergreen forests, sometimes near limestone escarpments (Laos), at elevations of 100-1300 m.

Food and Feeding. No information.

Breeding. Pregnant Kachin Woolly Bats were captured in mid-April and lactating females in late May in Laos.

Activity patterns. The Kachin Woolly Bat might use narrow crevices as day roosts, as suggested by flattened braincase. In Loei Province, northern Thailand, call shape is steep FM sweep, with peak frequencies of 123-124-9 kHz (mean 123-9 kHz) and durations of 1-5-2-3 milliseconds.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Least Concern on The IUCN Red List. The Kachin Woolly Bat appears to be locally common in Thailand, Laos, and Cambodia. Little 1s known aboutits ecology and threats.
