Here we report on the ninth iteration of the biennial listing of a consensus of the 25 primate species considered to be among the most endangered worldwide and the most in need of conservation measures. The 2016–2018 list of the world’s 25 most endangered primates has five species from Africa, six from Madagascar, nine from Asia, and five from the Neotropics. 

This report is the seventh iteration of the biennial listing of a consensus of the 25 primate species considered to be among the most endangered worldwide and the most in need of conservation measures. The list includes 5 species from Africa, 6 from Madagascar, 9 from Asia, and 5 from the Neotropics. This publication includes comprehensive information about the threats facing these primates, with bibliographic references cited in the text.

This report, compiled by 85 experts from across the world, reveals that nearly half of all primate species are now in danger of becoming extinct from destruction of tropical forests, illegal wildlife trade and commercial bushmeat hunting. The list includes five primate species from Madagascar, six from Africa, 11 from Asia, and three from Central and South America, all of which are the most in need of urgent conservation action.
