Anatomy of copulatory organs and patterns of copulatory behavior were studied in three species of Macaca. The copulatory behavior of the rhesus monkey ( M. mulatta ) and crab‐eating macaque ( M. fascicularis ) were similar. Mounting time was longer in stump‐tailed macaque ( M. arctoides ) (48 seconds) than in the rhesus monkey or crab‐eating macaque (8.5 seconds). Species differences were correlated with anatomical differences in the female and male reproductive organs. In the stump‐tailed macaque the male has a relatively long penis, and the female has an elaborate vestibular colliculus in the vestibule. Both rhesus and crab‐eating macaques have a short penis, and the female has no vestibular colliculus. Under scanning electron microscope, cone‐like projections (3–4 mm) were observed on the surface of the glans and corpus penis of M. arctoides. In M. fascicularis shorter projections (0.05–0.1 mm) were observed on the glans penis but not the corpus penis.
