Murina feae

French: Murine de Fea / German: Fea-Rohrennase / Spanish: Ratonero narizudo de Fea

Other common names: Ashy Tube-nosed Bat

Taxonomy. Harpiocephalus feae Thomas, 1891,

Biapo, Karin Hills, Myanmar.

See M. tubinaris . Limited genetic data suggest M. feae may be closelyrelated to M. beelzebub and M. annamitica; see also M. jaintiana. Typically treated as a synonym of M. aurata, but is now considered a distinct species. Includes populations of South-east Asia previously placed in M. tubinaris that were separated in 2011 as M. cineracea, but subsequently found to refer to M. feae . Monotypic.

Distribution. N & E Myanmar, N Thailand, N Laos, N Vietnam, and E Cambodia; may also occur in NE India.

Fur 1s long and silky; dorsally dark grayish (hairs dark grayish brown to blackish for basal two-thirds, with bufty gray band and dark gray-brown tip, some hairs appearing browner); ventrally paler silvery gray (hairs with dark gray or black basal three-quarters, and silvery white tips). Dorsal pelage extends sparsely onto wings, uropatagium, thumbs, and feet. Face is sparsely haired except long protuberant nostrils, which are naked. Ears are short, broad, and evenly rounded, with smoothly convex anterior margins, lacking notch on posterior margin, with broadly rounded tip; tragus is long, narrow, and tapering toward pointed tip. Wing attaches to base of claw on the toe. Skull has slightly domed braincase with distinct concavity in rostral profile; sagittal crest is weakly developed. C' is higher than P* and P? is about half P* height; mesostyles of M' and M? are poorly developed; C, exceeds height of P, and P; talonids of M, and M,are about equal to their trigonids. Chromosomal complement has 2n = 44 and FN = 50 (Vietnam).
