Barbara Brown's titi monkey

Barbara Brown's titi monkey (Callicebus barbarabrownae) is a titi monkey in the genus Callicebus, family Pitheciidae, the New World monkeys that also include the other titis, the sakis and the uakaris. The Mammal Diversity Database credits the species name to Hershkovitz, 1990 and lists its country distribution as Brazil. It is also known as the blond titi monkey or northern Bahian blond titi, and the English Wikipedia article describes it as critically endangered and endemic to the Caatinga of northeastern Brazil, with fewer than 250 mature individuals estimated to remain. The common name honours the zoologist Barbara Elaine Russell Brown. The Mammal Diversity Database gives its IUCN Red List status as Critically Endangered.
