<p>Owl monkeys (<i>Aotus</i> spp.) are socially monogamous, yet allogrooming is reported to be rare. Because <i>Aotus</i>
are nocturnal and arboreal, allogrooming is difficult to observe in
natural settings. We observed 21 male-female pairs of captive <i>Aotus nancymaae</i>
during 2 nonconsecutive study periods in order to describe the details
of allogrooming between mates (partner grooming). We found that grooming
bouts are brief and consist of tugging the hair or skin with flexed
fingers and/or the mouth. Males groomed females most often, and their
rates of partner grooming were negatively related to age. Partner
grooming occurred regardless of mating behavior. Camera trap data
revealed that the rate of partner grooming (1.50 bouts/h) is greater
than that recorded from our direct observations in the early evenings
(0.51 bouts/h, in 2013; 0.37 bouts/h in 2003) given that most bouts
occurred later in the night. A positive relationship between the rates
of the parents' partner grooming and those of their offspring later in
life suggests intergenerational transmission. This relationship is
influenced by the fathers' rates of partner grooming. We conclude that
allogrooming in <i>Aotus</i> is a normal part of their behavioral
repertoire that likely serves social functions similar to those in other
pair-bonded primates.</p>
