INTRODUCTION

Since Landsteiner and Miller (1925) first showed human ABO-like antigens in chimpanzees, several reports have been published on other non-human primates, especially the great apes and Old World monkeys. However, few New World monkey species have been studied, even though they are widely used in biomedical research. Among the 53 New World monkey species belonging to 16 genera, no more than 4 Ateles, 2 Cebus (including subspecies), 2AIouatta, and 5 Saguinus have been studied, including some Saimbi specimens (Table I). Since some Aotus specimens have been used as biomedical models for the study of malaria, as well as in other areas of biomedical and behavior research, these animals have become extremely valuable.

For this reason, it is most important to genetically characterize these species, especiaily with respect to those traits they share with man.
In this paper, we present the first report on the ABO blood groups in natural populations of A. nancymai and A. vociferans.
