Lim and collaborators in 2003 confirmed that it is a distinct species. Monotypic.	From S Mexico ( Veracruz , Oaxaca , Tabasco , and Chiapas ) through Central America (except dry Pacific slope and Yucatan Peninsula) to W Colombia , Venezuela , Guyana , French Guiana , and W Ecuador , and through the Amazon Basin of Colombia , Venezuela , N & W Brazil , Ecuador , Peru , and Bolivia .	Head-body 43-52 mm (tailless), ear 11-15 mm, hindfoot 7-10 mm, forearm 29-34 mm; weight 6-10 g. The Northern Little Yellow-eared Bat is very small, among the smallest in the family. Dorsal pelage is pale brown; hairs are tricolored, with brown bases, central portion creamy-white, and paler tips. There is no median back stripe. Facial stripes are indistinct, most often looking like small paler spots above and below eyes. Tragus, entire base of ear, and upper edges of ears are yellow; noseleafis mostly brown, with yellow edges. Uropatagium is short, with light fringe of yellowish hairs along middle posterior border. Legs and feet are sparsely haired. Forearms, fingers, and thumbs are brown. Skull has short, broad rostrum, and postorbital processes are weakly developed. I? are elongated and roughly evenly bilobate, converging distally but not in contact at tips, and more than twice as high as I*. Upper molars are broader than long; lower incisors are small, completely filling space between canines, and their cutting edges are faintly trilobate. P® is one-half or less the size of P*, and the latteris triangular, with well-developed cingulum. M, is quadrate-shaped, with large protoconid and small hypoconid. M, has large metaconid and blade-like entoconid of about the same length as metaconid. M, is absent. Dental formula is I 2 /2, C 1/1, P 2/2, M 2/2 ( x2 ) = 28. There are three chromosomal complements: 2n = 18 and FN = 20 in Honduras and Nicaragua ; 2n = 23/24 and FN = 22 in Colombia and 2n = 22/23 and FN = 22 in northern Peru , with a sex-chromosome system XXXXXX.Y, with the Y-chromosome translocated to the autosomes.	Mostly well-preserved humid forests and also disturbed secondary forests, rarely croplands, modified habitats, and dry habitats at elevations up to 1500 m (most commonly below 800 m ).	Fruits in diets of Northern Little Yellow-eared Bats include a high proportion of Ficus spp. ( Moraceae ) and other small fruits; it qualifies as a fig specialist in Panama . Samples from Costa Rica showed a cultivated fruit-bearing tree as a source of food. Most stomach contents had fruit pulp.	Northern Little Yellow-eared Bats reproduce twice a year, with young born late in dry season and middle of wet season. Pregnant and lactating females have been recorded year-round, suggesting bimodal polyestry.	Greatest activity of Northern Little Yellow-eared Bats occurs during the first two hours after sunset, but they can be active throughout the night. They are usually caught in nets set across streams, preferring to fly in forest subcanopies rather than understories. Known roosting sites include bushes and tree branches. They make tents from Philodendron and other aroids. Availability of suitable leaves to build tents could determine distribution and local abundance.	Roosting groups of Little Yelloweared Bats are composed of one to five individuals.	Classified as Least Concern on The IUCN Red List. Although the Northern Little Yellow-eared Bat is not locally common, its distribution is very wide, diminishing potential threats to its overall population.	Arroyo-Cabrales (2008b) | Baker et al.

It is also adaptable to habitat change. This species should be reassessed following taxonomic revision.	This bat is found in semi-deciduous and evergreen forest. ;It is found in a variety of habitat types. ;Its roosts in tents ;(Timm 1984, Kunz ;et al . 1994) ;made from philodendron and other heart-shaped leaves. The basal nerves and midrib are chewed near the leaf stem, causing the sides and tip of the leaf to fold down. Tents are occupied by one to five individuals. This species has the greatest activity during the first two hours after sunset. ;It is a frugivore and figs and other small fruits are eaten. Reproduction may occur twice annually, with young born late in the dry season and in the middle of the wet season (Kunz et al.  1994, Reid 1997). ;As with other members of the genus, the ecology is not well known.	There are no major threats known as this species is adaptable to human land-uses. Habitat loss is a threat in some parts of the range.	This species is uncommon but widespread (Reid 1997) in Mesoamerica, but is common throughout its range in South America. It can be locally common (Tavares pers. comm.).	Unknown	This species occurs throughout Oaxaca and Veracruz (Mexico) to Bolivia, Peru, Venezuela, Guyana and French Guiana (Simmons 2005). It also occurs in northern and western Brazil (Tavares pers. comm.). It occurs up to 1,000 m asl (Molinari pers. comm.) in the Andes. There is a record from Chiapas, Mexico (Reid pers. comm.). ;The last record is from Amazonian Brazil (Tavares pers. comm.)	This species is not used.	Terrestrial	The recommended conservation action is to reduce habitat loss. Further studies of the basic ecology, threats and taxonomy are required.	Neotropical		FALSE	FALSE	Global	Simmons, N.
