The big crested mastiff bat (Promops centralis), is a bat species from South and Central America.


It was described as a new species in 1915 by British zoologist Oldfield Thomas. The holotype had been collected by George F. Gaumer, and was presented to Thomas via Osbert Salvin.[2]


It can be differentiated from the other species of Promops, the brown mastiff bat, by its longer forearm. The brown mastiff bat has a forearm length less than 50 mm (2.0 in), while the big crested mastiff bat has one greater than 51.5 mm (2.03 in). It has a dental formula of for a total of 30 teeth.[3]

Biology and ecology[edit]

It is a social animal, roosting in small colonies of up to 6 individuals during the day. These roosts consist of the space underneath tree bark, the undersides of palm leaves, or tree hollows.[3] It navigates and detects prey using echolocation. Its search calls have an average duration of 20.6 ms, with a starting frequency of 23.0 kHz, an ending frequency of 25.6 kHz, and a peak frequency of 24.7 kHz.[4]

Range and habitat[edit]

The big crested mastiff bat is found in Central and South America. It is found in the following countries: Argentina, Belize, Bolivia, Brazil, Colombia, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Paraguay, Peru, Suriname, Trinidad and Tobago, and Venezuela. It is found at a range of elevations, from sea level to 1,800 m (5,900 ft) above sea level.[1]
