Mexican dog-faced bat

The Mexican dog-faced bat (Cynomops mexicanus) is a free-tailed bat of the family Molossidae found in Central America from Nayarit in Mexico south to Costa Rica, at elevations up to 1,500 metres. It roosts in deciduous and evergreen forest, usually near small bodies of water, and is nocturnal, sheltering by day in places such as hollow trees. It is a relatively large free-tailed bat, with a total length of 90 to 107 millimetres, a forearm of about 35 to 37 millimetres, a weight of about 16 grams and dark brown or reddish brown fur that is lighter on the belly. It was described in 1967 by Jones and Genoways as a subspecies of Greenhall's dog-faced bat and was promoted to a full species only in 2002, and it is the most basal member of the genus Cynomops. The species name mexicanus is Latin for from Mexico.
