Aotus lemurinus (I. Geoffroy, 1843), Quindio, Dept. of Caldas, Colombia. Originally included in the species Aotus trivirgatus, the gray-bellied night monkey is now allocated to the separate species Aotus lemurinus, containing 4 subspecies (lemurinus, brumbacki, griseimembra, and zonalis). It is quite possible that one or more of these subspecies may actually be a full species, and that one may be the same as A. lemurinus lemurinus.
