However, the margins of rivers can present denser riparian forests, with arborescent ferns, orchids, lianas and several trees with more than 10 m in height (

). Ears are Mummy Brown and comparatively medium sized (EL 11-14 mm), reaching the portion of the rostrum between the eyes and nostrils when extended forward. Tragus is long and slender, with a wide base and a narrower spear-shaped terminal half, almost straight anterior edge, and rounded tip. Membranes are Mummy Brown; the dorsal surface of tibia, and uropatagium has scattered hairs extending to the level of the knees. The uropatagium lacks the fringe of hairs along the trailing edge. The plagiopatagium is attached to the foot at the level of the toes by a broad band of membrane.
Dorsal and ventral fur are wooly and long (LDF 7-9 mm, LVF 6-7 mm). The dorsal pelage is bicolored with brownish-gray bases (3/4 of the total fur length) and reddish tips (1/4 of the total fur length), ranging from Dresden Brown to paler Ochraceous-Tawny. The dorsal fur has a coloration that looks like the bat is partially covered by soot and with the tip of the hairs burned. The ventral fur is tricolored, with Drab bases (1/4 of the total fur length) progressively turning Smoke Gray in the middle band (2/4 length) and light-yellow tips (1/4 [ranging from Naples Yellow to Cream-Buff]). The tricolored ventral fur is unique among all South American

The 1st lower molar (m1) is myotodont, with the postcristid connecting hypoconid and entoconid. Braincase delicate and elongated; sagittal crest and lambdoidal crests are absent or very low; the occipital region is rounded and projects beyond the posterior limits of the occipital condyles; mastoid processes weakly developed. Frontal bone slightly sloping; rostrum comparatively short and narrow.
