New records to three Neotropical primates to Minas Gerais and Mato Grosso States and small expansion of occurrence area to Cebus libidinosus Spix, 1823

Recent compiled papers demonstrate several gaps in occurrence records and distribution limits mainly due to information deficiency, hindering the management and planning of preservation and conservation efforts. Therefore, the objective of this study is to present and analyze new records of four Neotropical Primates species: Callicebus moloch, Mico emiliae, Ateles marginatus and Cebus (Sapajus) libidinosus. Data collection was assessed by interviews, census on pre-existing trails and direct observations. The expeditions took place in the cities of Pains (Minas Gerais state), Serra do Salitre (Minas Gerais state) and Guarantã do Norte (Mato Grosso state). Mico emilie, C. moloch and A. marginatus were recorded in Guarantã do Norte and C. libidinosus was recorded in Serra do Salitre and Pains. A small expansion of occurrence area to C. libidinosus was observed. We recommend new mammal inventories in order to understand the faunal diversity in these areas and propose new conservation actions
