Descriptive notes. Head-body 47-49 mm, tail 41-45 mm, ear 16-4—17- 4 mm, forearm 37-42 mm. Females are reportedly larger than males. Fur is long and woolly; dorsally reddish brown (hairs with black basal half, light gray middle, and orange to dark brown tips, and guard hairs with reddish tips); ventrally yellow (hairs yellow-tipped with dark bases), sometimes with uniformly white or yellowish-white chest. Dorsal fur extends onto base of wings, uropatagium, thumbs, and feet, with well-developed fringe of hairs around margin of uropatagium. Dark face mask around the eyes, muzzle, and lower forehead, and face is furred except long, protuberant nostrils, which are naked. Ears are short and broad with smoothly convex anterior margins, distinct notch on posterior margin, and broadly rounded tip; tragusis long, narrow, and tapering toward pointed tip, with slightly convex anterior margin, concave posterior margin above, slightly convex below, and a basal notch. Wing attaches close to base offirst toe. Compared with the Rufous Tube-nosed Bat (M. leucogaster), upper canine is anteriorly and posteriorly more compressed, and females have longer skull, narrower zygomatic width, narrower braincase, and narrower mastoid width; rostrum is heavily built; sagittal crest is weak or absent; lambdoidal crests are weak. C' is relatively small compared to other large Murina; I? is anteriorly positioned relative to I*; P? is about half the size of P*; mesostyles of M' and M? are moderately developed.
