The Guianan bonneted bat, or Thomas's mastiff bat, (Eumops maurus) is a species of free-tailed bat from South America. It is poorly understood, because it is difficult to capture, and may be one of the rarest Neotropical bats. [1]

Description

The Guianan bonneted bat appears similar to other mastiff bats, with a body about 18 cm (7.1 in) long, and a tail measuring about 4 cm (1.6 in). The fur is dark chocolate brown in colour, and only slightly paler on the underside than on the rest of the body. The most distinctive feature is a narrow band of white hair running along each flank to the forward part of the mesopatagium. The ears are large and rounded, positioned close together at the base, and mostly hairless, with a small tragus and long antitragus. [2]

The wings have narrow tips, and are covered in fur to about half the way along the humerus and femur. The uropatagium is also furred for about a third of its area, and is bounded by long calcars running for about three quarters of the length of the membrane edge. Overall, the wing membranes are pale brown in colour. Males also possess a prominent gland on the throat that is either missing or extremely small in females. [2]

Distribution and habitat

The Guianan bonneted bat is found primarily in Guyana and Suriname, but may also be found in neighbouring parts of Brazil and Venezuela. [2] Little is known of the bat's habitat preferences, but it has been found in humid lowland evergreen forests and pine plantations. [3]

A surprising report has been made from Ecuador.[ citation needed ] It is probably threatened by habitat loss. [3]

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

The Molossidae, or free-tailed bats, are a family of bats within the order Chiroptera. The Molossidae is the fourth-largest family of bats, containing about 110 species as of 2012. They are generally quite robust, and consist of many strong-flying forms with relatively long and narrow wings with wrinkled lips shared through their genus. Their strong flying form allows them to fly 60 miles per hour using tail winds and at altitudes over 10,000 feet. This makes them unique among bats, as they are the only bat family that withstands the elevation. They are widespread, being found on every continent except Antarctica. They are typically found in caves, abandoned mines, or tunnels.

The European free-tailed bat is a species of free-tailed bat found in the Old World. Other common names include the bulldog bat and the mastiff bat because of the presence of wrinkling on the snout. This bat is found in the Mediterranean region of Europe and in scattered locations across Asia at altitudes from sea level to 3100 m. The range of distribution is from the Canary Islands and Madeira through the whole Mediterranean area, Asia Minor, the Caucasus and the Middle East. In the north to southern France, southern Germany, Switzerland, Croatia and Bulgaria. It was reported from Korea in 1931, but has not been sighted on the Korean Peninsula since then. Populations in Japan, Taiwan and Korea are now considered to be a separate species Tadarida insignis.

It is found in the Western United States, Mexico and South America. This species is the largest bat native to North America, and some of its distinguishing characteristics are its large ears, wings, and forearms. The subspecies Eumops perotis californicus is a species of concern as identified by the U.S. Fish and Wildlife Service. The range of this subspecies is principally southwest desert regions of the United States, along the border with Mexico; however, the range extends as far north on the Pacific coast as Alameda County, California.

<span class="mw-page-title-main">Florida bonneted bat</span> Species of bat

The Florida bonneted bat or Florida mastiff bat is a species of bat in the genus Eumops, the bonneted bats or mastiff bats. Until recently, it was classified as a subspecies of Wagner's bonneted bat . It is endemic to southern Florida in the United States. This species has one of the smallest geographical distributions of any New World bat. It has been called "one of the most critically endangered mammal species in North America". It is protected under the Endangered Species Act.

<i>Eumops ferox</i> Species of bat

Eumops ferox, the fierce bonneted bat or the chestnut mastiff bat, is a species of free-tailed bat found in the Caribbean and Mexico. Until recently, it was synonymous with Wagner's bonneted bat.

Eumops wilsoni is a species of bat native to Ecuador and Peru. The bat has a distinct karyotype, sequence of the mitochondrial cytochrome-b gene, and other distinct genetic markers that distinguish it from closely related bats such as Eumops glaucinus and Eumops ferox. However, there are no morphological distinctions from those related species and thus there is uncertainty of its geographic distribution and population status, leading to its classification as "data deficient". Local threats to the bat's dry forest habitat further impede efforts to study the bats. Transition to farmland and urbanization threatens the dry forest habitat of the bat in the Andes. As an endemic species, the bat may be threatened by this habitat loss.
