First record of black-tufted marmoset Callithrix penicillata (É. Geoffroy, 1812) (Primates, Callitrichidae) in Northern Paraná, Brazil

Invasive species always endanger biodiversity because of their competing efficiency for food resources, high reproduction, and dispersion capacity. The aim of this study is to report the first record of 10 specimens of a small-sized primate, Callithrix penicillata, introduced in an Atlantic Rainforest fragment, Northern Paraná, Brazil. Due to their generalist feeding habit, behavior flexibility and parental care, the species adapted itself to different habitat and types of food. The monitoring of the group should be enhanced since the characteristics of the environment which provides them with food and shelter, coupled to the forced placement of the specimens in the fragments, may establish the species in the area
