Dorsal pelage is orange (hairs with pale buff bases and orange-browntips), with longer guard hairs scattered throughout; venter is pale buff orange and whiter near chin (hairs unicolored buff orange). 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; tragusis long and narrow and tapers toward pointed tip. Wing attaches near base of claw on first toe. Baculum has upwardly arched dorsal surface and deeply concave ventral surface, being somewhat heartshaped (small notch at tip and pointed at base) in dorsal view and very short (1- 1 mm long). Skull is large and robust, with well-domed braincase; sagittal crest is very well developed, and lambdoidalcrest is weakly developed; I? is lateral to I; C! is much taller than P*, but basal area is only slightly larger or subequal to that of P*; P? is subequalto P*in height, but its basal area is two-thirds to nearly equal to that of P*; M' and M? lack mesostyles; and talonids of M, and M, are reduced relative to their trigonids.
