Summary S aguinus niger is a primate of the family C allitrichidae, with a geographical distribution limited to northern B razil, G uyanas, S uriname and V enezuela, where it inhabits rainforests along the coast. Three adult females from the Paragominas Bauxite Mine – PA were used, donated to the Laboratory of Animal Morphology Research ( LAMR ) of the Federal Rural University of A mazonia. These animals had died of natural causes. The arterial system was filled with latex, and the animals were fixed in 10% formalin. Afterwards, the abdominal aorta and its collateral branches were dissected. The arrangement of the abdominal aorta branches in this species showed a similar arrangement as domestic animals but differing in the formation of the coeliac trunk. The coeliac trunk originates from the abdominal aorta, and from this trunk, we found the hepatic, left gastric and splenic arteries, where the origin of these vessels was variable. These arteries originate from the coliac trunk or a common trunk originating from the coeliac trunk, a characteristic not described in other species. The other branches of the abdominal aorta from S . niger did not show great differences in origin when compared to other species.
