Based on neotype designation, restricted by A. L. Gardner and D. C. Carterin 1972 te “ 2 mi. [=3: 2 km] N Tingo Maria, 2000 ft. [= 610 m], Provincia de Leoncio Prado, Departamento de Huanuco, Peru.” Vampyrops fumosus by G. S. Miller, Jr. in 1902 from “Purus River, Brazil ” and Vampyrops intermedius by C. J. Marinkelle in 1970 from Meta, Colombia are considered junior synonyms. Monotypic. <b>Distribution.</b> Colombia, E Ecuador, E Peru, NW Brazil, and Bolivia. <b>Descriptive notes.</b> Head—body 77-105 mm (tailless), ear 20-25 mm, hindfoot 14— 18 mm, forearm 55-61 mm; weight 36-59 g. The Buffy Broad-nosed Bat is mediumsized to large. Fur is dense and soft. Dorsalfur is buffy to dark brown, not blackish, and less than 6-3 mm long; thin and inconspicuous white line runs from crown to base of caudal membrane; and underparts are grayish brown to light brown and paler than back. Head is robust, and snout is short and broad, with four inconspicuous (grayish) parallel stripes, less pronounced than in most congeners. Noseleafis fleshy, large, and spear-shaped; edges of noseleaf are dark, never bright yellow; and lower rim is free. Ears are large and rounded, and edges are sometimes pale but never yellow. Elbows are densely furred and buffy to dark brown; some individuals have whitish wingtips; caudal membrane is very short in middle, with deep V-shaped groove, and edge has dense short hairs; and upper sides of feet have sparse short hairs. I' converge and are broad, with parallel tips, and twice as long as I&gt;. M' parastyle is present. Occlusal outline of M,is longer than broad. Chromosomal complement has 2n = 30 and FN = 56. X-chromosome is subtelocentric, and Y-chromosome is submetacentric. <b>Habitat.</b> Tropical, subtropical, and lower temperate forests, including primary, secondary, altered, and gallery forests, forest edges near cultivated areas, and fairly open country at elevations of 180-2200 m. The Buffy Broad-nosed Bat prefers humid forests and only rarely occurs in dry forests. <b>Food and Feeding.</b> The Buffy Broad-nosed Bat feeds almost exclusively on fruits, such as seeds of Cecropia (Urticaceae), although it might eat some leaves. <b>Breeding.</b> In Colombia, a pregnant Buffy Broad-nosed Bat and three lactating females were found in March. In Ecuador, pregnant females were found in October—January, and lactating females were captured in March and May. In Bolivia, two lactating females and a scrotal male were found in November. <b>Activity patterns.</b> The Buffy Broad-nosed Batis nocturnal. It has been found resting in large and shallow caves and leafy tangles. It often flies in interior forest or over streams. <b>Movements, Home range and Social organization.</b> Buffy Broad-nosed Bats roost in small groups (3-5 individuals). <b>Status and Conservation.</b> Classified as Least Concern on The IUCN Red List. The Buffy Broad-nosed Batis fairly common, butlittle is known about the Brazilian population. Its conservation status is considered stable, and it occurs in several protected areas. <b>Bibliography.</b> Albuja (1999), Arguero et al.
