French: Murine du Hkakabo Razi / German: Hkakabo-Razi-Réhrennase / Spanish: Ratonero narizudo de Hkakabo Razi

Taxonomy. Murina hkakaboraziensis Soisook et al., 2017,

“ Myanmar, Kachin, Putao Township, Hkakabo Razi National Park (proposed southern extension), 6 km north of Mali Raing Village, 27°37 19" N, 97°22'15E, 510 m a...”

Murina hkakaboraziensis appears to be closely related to M. kontumensis based on limited genetic data. Monotypic.

Distribution. Known only from type locality in Hkakabo Razi National Park in N Myanmar.

Descriptive notes. Head—body 35- 5 mm, tail 30- 1 mm, ear 17 mm, hindfoot 8- 6 mm, forearm 29- 6 mm; weight 3-4 g. Fur long and silky. Dorsal pelage is orange-brown (hairs with grayish brown bases and orange-brown tips), with longer golden orangetipped hairs mixed throughout that are most dense on head and forehead; venter is whitish gray (hairs with very dark bases, gray middles, and whitish gray tips). Head has distinct dark brown facemask around eyes, with contrasting whitish collar around neck. 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, slight notch on posterior margins, and broadly rounded tips; tragus is long and narrow and tapers toward pointed tip. Wing attaches near base of claw on first toe. Baculum is very small (0-8 mm long) and somewhat rectangular without constriction on sides; dorsal side is arched upward. Skull has deep and bulbous rostrum and high but not distinctly domed braincase; sagittal and lambdoidal crests are absent; C! hasslightly larger height than P*; P* is slightly less than one-half the height of P*; M' and M? have well-developed mesostyles; and talonids of M| and M, are subequalin size totheir respective trigonids.

Habitat. Edge of lowland semi-evergreen forest transitioning to open grassland at an elevation of 510 m (type locality).

Food and Feeding. No information.

Breeding. No information.

Activity patterns. Based on a single poorly recorded call from the holotype, calls have steep FM sweeps, with end frequencies of 62-70 kHz, peak frequencies of 148-5- 152-8 kHz, durations of 3-3-8 milliseconds, and interpulse intervals of 69-1-75-3 milliseconds. Start frequency was impossible to measure accurately, but highest frequencies detected were 164-169 kHz.

Movements, Home range and Social organization. No information.

Status and Conservation. Not assessed on The [UCN Red List. The Hkakabo Razi Tubenosed Bat is currently only known from one specimen, and virtually nothing is known about it ecology and threats.
