Tshuapa red colobuses (Piliocolobus tholloni) are endemic to the DRC. Primarily leaf-eaters; their low-nutrient diet and complex digestive system make them slow-movers and vulnerable to hunting. Also threatened by habitat loss. Vulnerable. Photo: © Gabriel Jamie/iNaturalist/CC4.0.

Crowned lemurs (Eulemur coronatus) are endemic to northern Madagascar. Sexually dimorphic, females are light gray with pale orange crowns, and males are reddish-brown with striking black and orange crowns. Populations are decreasing due to habitat loss and forest fragmentation. Listed as Endangered.

Vieira's titis (Plecturocebus vieirai) are endemic to Brazil in a region referred to as the “Arc of Deforestation,” with the highest rates of forest loss. Threatened by severe habitat loss due to expansion of agriculture, cattle ranching, human settlements, and infrastructure. Critically Endangered.
