The Maués marmoset^[1] (Mico mauesi) is a marmoset native to Brazil. It is only found on the western bank of the Maués Açu River in the state of Amazonas.

• The Maués marmoset is chocolate brown above, with faint grayish stripes on its back, silver stripes on its thighs, and an orange underside.
• The face has a black circumbuccal area that is otherwise pink with silvery-brown cheek patches.
• The ears are surrounded by thick tufts of silver-brown fur held unusually erect; the overall impression was described as “neatly cropped“.
• The feet are a light orange tint, and the tail has a hint of narrow white rings.

• Maués marmosets are arboreal and diurnal, spending most of their lives in trees.
• They remain within their home range as they traverse the forest canopy, depending on the availability of plant exudates.
• These marmosets wake up 30 minutes after sunrise and eat intensely for an hour; the rest of the day is spent foraging, socializing, and resting.
• Common marmoset groups retain their juvenile members until adulthood, after which the males migrate to other groups.
• The dominance hierarchy in marmoset species is related to reproductive status. Typically, a breeding pair dominates the family and maintains its status through the aggressive defense.
