  • The lesser long-nosed bat (Leptonycteris yerbabuenae Martínez & Villa-R, 1940) is a specialized nectar feeding species found from southern USA to Nicaragua in Central America, mostly in dry forest. We sampled bats using mist nets and Anabat detectors, and also looked for them at refuges and other sites in Honduras from 2011 to 2016. The lesser long-nosed bat is known in Honduras from only two localities in the southern dry forests below 100 m elevation, and there are no recent records of this species in the country. Our objective is to report new records on distribution and habitat of the lesser long-nosed bat in Honduras. We found eight lesser long-nosed bats at Cerro de Hula, Francisco Morazán department in 2012, and 10 at La Anonilla, Choluteca department, southern Honduras in 2015. Based on these 18 individuals of the lesser long-nosed bat, we report two new localities in Honduras, an altitude record, and the use of another habitat other than the dry forest. The highest point registered was at 1710 m a.s.l. in pastureland with forest remnants in an area heavily impacted by human activities. The new localities are found in the Subtropical Moist Forest. Populations of long-nosed bats in Honduras are probably resident and may include altitudinal movements. Although this species has been described widely in North America, its behavior in Honduras is practically unknown. It is a key species for the tequila and mezcal industry, but its range extends beyond the tequila production area, where it maintains a key role as a pollinator and link between habitats. As a result, research and conservation efforts should be an international goal.
