The Cuban funnel-eared bat (Chilonatalus micropus) is a species of bat in the family Natalidae. It is one of two species within the genus Chilonatalus and is found only in the Caribbean. [1] [2]

Description

All natalids have large, funnel-shaped ears, with glandular papillae on the surface of the external ear. They also have a short, triangular tragus, which is quite thick, but they lack a true nose leaf. All species in this family, however, have a hairy protuberance on the tip of the snout that resembles a nose leaf. The eyes are not prominent. The oval nostrils are set close together and are located near the margin of the lip.

One special characteristic of natalids is a peculiar structure on the face or muzzle of adult males. This structure is commonly known as the "natalid organ." It is made up of sensory cells, but it could actually be involved in glandular functions. There is not enough known about this structure to comment upon it further, but it seems to be found solely in the Natalidae.

All funnel-eared bats have long, slender wings and legs that are quite fragile. The thumbs are also very short, but possess their own flight membranes. In addition, the second finger lacks bony phalanges. The tail is about as long as or longer than the legs and is completely enclosed in the tail membrane, the uroplagium.

This species has many special characteristics which set it apart from the others in the family. Chilonatalus micropus is the smallest and most delicate bat in the New World. The lower lip of this species is reflected outward. It also possesses a small, horizontal cutaneous projection on the other side. This structure looks much like a second lower lip. The pregnant female will move away to the darkest and hottest area.

Chilonatalus micropus has a very dense and long coat. Coat color varies depending on its location on the body. Dorsally, the fur is pale yellowish brown at the hair base with tips that are either reddish or chestnut-brown. Ventrally, the hair is pale yellowish-brown throughout.

The dental formula is 3.1.3.33.1.3.3. These bats have a well-developed "W" tooth pattern. The 3rd incisor is separated from the other two. The canine is small but well developed and is noticeably set apart from the other teeth. The premolars are all in close contact with the other teeth and the molars are approximately equal in size and form.

There seems to be no sexual dimorphism. [3]

Distribution and status

It is found in Colombia's Archipelago of San Andrés, Providencia and Santa Catalina, Hispaniola (the Dominican Republic and Haiti), and Jamaica in the Caribbean. [1] A conservation plan has not been put into place yet because the Cuban funnel-eared bat is so rare that we do not know enough information about their habitat requirements, reproductive cycle or life history to create one.

<span class="mw-page-title-main">Microbat</span> Suborder of mammals

Microbats constitute the suborder Microchiroptera within the order Chiroptera (bats). Bats have long been differentiated into Megachiroptera (megabats) and Microchiroptera, based on their size, the use of echolocation by the Microchiroptera and other features; molecular evidence suggests a somewhat different subdivision, as the microbats have been shown to be a paraphyletic group.

<span class="mw-page-title-main">Leaf-nosed bat</span> Family of bats

The New World leaf-nosed bats (Phyllostomidae) are found from southern North America to South America, specifically from the Southwest United States to northern Argentina. They are ecologically the most varied and diverse family within the order Chiroptera. Most species are insectivorous, but the phyllostomid bats include within their number true predatory species and frugivores. For example, the spectral bat, the largest bat in the Americas, eats vertebrate prey, including small, dove-sized birds. Members of this family have evolved to use food groups such as fruit, nectar, pollen, insects, frogs, other bats, and small vertebrates, and in the case of the vampire bats, even blood.

The family Natalidae, or funnel-eared bats, are found from Mexico to Brazil and the Caribbean islands. The family has three genera, Chilonatalus, Natalus and Nyctiellus. They are slender bats with unusually long tails and, as their name suggests, funnel-shaped ears. They are small, at only 3.5 to 5.5 cm in length, with brown, grey, or reddish fur. Like many other bats, they are insectivorous, and roost in caves.

Furipteridae is family of bats, allying two genera of single species, Amorphochilus schnablii and the type Furipterus horrens. They are found in Central and South America and are closely related to the bats in the families Natalidae and Thyropteridae. The species are distinguished by their reduced or functionless thumbs, enclosed by the wing membranes, and their broad, funnel-shaped ears. They are insectivorous and can live in many different kinds of environments. They have greyish fur, and a small nose-leaf. Like many bats, they roost in caves.

Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, and moist savanna. It is an uncommon species and its biology is poorly known. It was first described in 1774 by the German naturalist Johann Christian Daniel von Schreber, who named it Vespertilio nigrita. It was later transferred to the genus Scotophilus, making it Scotophilus nigrita.
