Descriptive notes. Head-body 49-9-56-5 mm, tail 4-4-6-4 mm, ear 9-12-1 mm, hindfoot 7-5-8: 3 mm, forearm 29-1-32.3 mm; weight 4-1-6 g. Dorsal fur of the Capixaba Nectarfeeding Bat is dark brown. Dorsal hairs are tricolored, with pale brown bases, beige middles, and dark brown tips. Venter is brown, slightly lighter than dorsum. Rostrum is elongated but shorter than braincase. Mandibular prognathism is evident. Chin has deep medial cleft, bordered by pair of dermal pads. Upper and lower lips are ornamented with well-developed vibrissae. Ears are round and small. Noseleaf is dark brown and relatively small, with no central rib. Wing membranes and uropatagium are dark brown. Plagiopatagium is inserted at bases of toes. Uropatagium is long and reaches distal part of tibia. Calcaris about the same length as foot. Tail is short, completely inserted in uropatagium. Rostrum is elongated and smaller than braincase, forming smooth slope in profile. Maxilla is inflated posteriorly. Basisphenoid pits are shallow, separated by wide septum. Zygomatic arches are incomplete. Palate is relatively long, broad, and U-shaped posteriorly. Mandibular condyleis level with coronoid process. Dental formula is 12/0,C1/1,P 2/3, M 3/3 (x2) = 30. Upper incisors are diminutive and separated from each other and from canines by a gap. C! is laterally compressed, and M' and M? are longer than M>.

Habitat. Humid, lowland Atlantic Forest. In Minas Gerais and Espirito Santo, the Capixaba Nectarfeeding Bat was captured in mature forest, with relatively open understory, canopy heights of 25-30 m, and emergent trees up to 40 m. One specimen from Sergipe was captured in well-structured forest surrounded by sugarcane plantations. It is also found in humid forest enclaves (“brejos de altitude”) in the Caatinga biome at elevations of ¢. 750 m.

Food and Feeding. Skull morphology and dentition of the Capixaba Nectar-feeding Bat suggest that it is a nectarivore.

Breeding. No information.

Activity patterns. Capixaba Nectar-feeding Bats were captured using ground-level mist nets set in clearings and borders and inside the forest. In Espirito Santo, one individual was captured at 18:05 h and another at 22:30 h.

Movements, Home range and Social organization. No information.

Status and Conservation. Not assessed on The IUCN Red List. Recent studies of the Capixaba Nectar-feeding Bat showed thatits distribution is much larger than previously assumed, and it has been found in relatively large protected areas in Minas Gerais and Espirito Santo.
