ABSTRACT

A new species of titi monkey, Catticebus, is described based on five specimens obtained from the state of Sergipe, north-eastern Brazil. It is a member of the Personatus group, but is easily distinguished from the other forms. The most noticeable differences are in the pelage coloration, the forehead, crown, and ear being black, and having a zebra-like, striped pattern on the anterior half of the back. Distinct features of its dental morphology and craniometry are also described.

Key words: Callicebus, Cebidae, new species, Personatus group, north-eastern Brazil

ACKNOWLEDGMENTS. Useful data on distributions and ecology of titi monkeys were offered by the following: A.F. Coimbra-Filho (ex-director of the Centro de Primatologia do Rio de Janeiro -CPRJ/FEEMA, Brazil), E. Wilson (Sytech 3, Brazil), and Leila M. Pessoa and João A. de Oliveira (Universidade Federal do Rio de Janeiro- UFRJ, Brazil). Special thanks are due to T. Setoguchi, Kyoto University, for supporting this study. The authors are grateful to M. Natori, Okayama Science University, and N. Shigehara and M. Aimi, Kyoto University, Japan, who critically reviewed earlier manuscripts of this paper. We also are most grateful to the following people and their staff for the many courtesies received during visits to their collections: Leda Dau (retired director of the Museu Nacional, Rio de Janeiro, Brazil), S.A.
