Greenhall's dog-faced bat

Greenhall's dog-faced bat (Cynomops greenhalli) is a South American bat species of the family Molossidae. It is found in Colombia, Peru, Ecuador, Venezuela, the Guianas, northeastern Brazil, and Trinidad.

This insect-eating bat measures 40–97 mm in length. It has yellowish-brown to black coloration on its upper body, and grey underneath, with a broad face and widely separated eyes. Its ears are short and rounded; the antitragus is square; its lips are not wrinkled; and a broad snout. It is mostly found at low elevations. Colonies of 50–77 roost in hollow branches of large trees. Males and females stay together throughout the year. The species is named after Arthur Greenhall, a scientist who led the rabies program at the Trinidad Regional Virus Laboratory in Port of Spain, Trinidad.
