The Ollala Brothers’ titi (Plecturocebus olallae) is a marmoset species of New World Monkeys native to Bolivia.

• There are about 110 to 150 individuals in the wild. The Ollala brothers’ Titis are small monkeys averaging 333 mm in length.
• Males are slightly larger than females, weighing an average of 991 grams, while females weigh 909 grams.
• These titi monkeys have long tails that are non-prehensile. In addition, they have long hind legs with an intermembrane index of 75.
• The chest and abdomen of the Ollala brothers’ titi are entirely orange to orange-brown. At the same time, the dorsal surface and limbs range from gray to agouti.
• The tail can be black or gray, with white tufts on the ears.

• Like all Neotropical primates (except Aotus), the Ollala brothers’ titi monkeys are highly diurnal.
• They usually sleep together in a vine-covered tree, often returning to the same tree night after night.
• Family groups are strongly territorial. A family group consists of an adult male and female and their young from several seasons.
• Family members groom themselves frequently, especially at midday rest. Within a family group, a pair of Titi monkeys will often sit with their tails intertwined.
• These animals are threatened by the rapid destruction of their habitat.
