what is it?
The Ecuadorian squirrel monkey ( Saimiri cassiquiarensis macrodon ) is a type of squirrel monkey. It had been considered a subspecies of the Guianan squirrel monkey, Saimiri sciureus , but was elevated to a full species, S. macrodon , based on a 2009 study by Carretero-Pinzón, et al . Based on subsequent genetic research by Jessica Lynch Alfaro, et al it was again reclassified as a subspecies of Humboldt's squirrel monkey.
