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.[1][2] 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.[1] 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).[1] However, reports from the latter habitats may actually represent M. gouazoubira.[1]
