The Amazonian brown brocket (Mazama nemorivaga), also known as the small brown brocket, is a small species of deer that is almost entirely restricted to South America. It is known from Panama (in Isla San José of the Pearl Islands only; endemic subspecies M. n. permira), Colombia, Venezuela, Guyana, Suriname, French Guiana, eastern Ecuador, eastern Peru, Brazil and possibly northern Bolivia. Habitats it is found in include primarily nonflooded Amazonian tropical rainforest, and locally also tropical deciduous forest and xeric shrublands, at altitudes up to 1,500 metres (4,900 ft). However, reports from the latter habitats may actually represent M. gouazoubira.
