The underwood leaf-nosed bat ( Hylonycteris underwoodi ) is a bat from the leaf-nosed family (Phyllostomidae) that is native to Central America. The genus Hylonycteris is monotypical , which means that apart from the Underwood leaf nose, no other species of the genus is known.
The generic name Hylonycteris is Greek and means "forest bat". The species name underwoodi honors Cecil F. Underwood (1867–1943), who collected the holotype .
description
With a forearm length of 31.5 to 34.2 mm, an overall length of 67 mm on average and an average weight of 6.6 g for males and 8.5 g for females, the Underwood leaf nose is a relatively small flower bat . Like all members of this subfamily, the Underwood leaf nose has an elongated snout and a very long tongue. Belonging to the family of leaf noses , it also has a clearly visible nasal leaf . The tail is short and the tip protrudes slightly from the tail membrane. The ears are small and round, the fur is black-brown in color, with a lighter tint on the belly side.
Way of life
Little is known about the Underwood leaf nose. Like most bats, the species is nocturnal and feeds primarily on nectar and pollen . Their diet makes them an important pollinator of night-flowering plants, such as Marcgravia , Mucuna , Calyptrogyne , Werauhia or cactus plants such as Weberocereus tunilla . During the day, the species hangs in small groups in caves and hollow tree trunks, sometimes probably also in buildings.
The females give birth to a single young each.
distribution
The Underwood leaf nose occurs from central Mexico to southern Honduras , as well as in Costa Rica and near the border in Nicaragua and in western Panama .
Hazard and protection
The IUCN assesses Hylonycteris underwoodi as safe thanks to its wide distribution and occurrence in protected areas.
Systematics
Hylonycteris underwoodi is classified as an independent species within the monotypical genus Hylonycteris . The first scientific description comes from Oldfield Thomas from 1903, who described an individual from the area around San José , the capital of Costa Rica .
