Taxonomy. Callicebus regulus Thomas, 1927 View in CoL ,
Fonte Boa, upper Rio Solimoes, Amazonas, Brazil.
C. regulus was considered to be a subspecies of C. torquatus until the review of M. van Roosmalen and colleagues in 2002. It is a member of the C. torquatus species group. It is sympatric with C. cupreus throughout its distribution, and the two species undoubtedly have distinct habitat preferences and ecological adaptations.
Monotypic.
Distribution. SW Brazilian Amazon (Amazonas State), S of the Rio Solimoes, E of the lower RioJavari, and W of the lower Rio Jurua; the S limit of its geographic distribution remains unclear. View Figure
Descriptive notes. Head-body 38-44 cm (males) and 37-45 cm (females), tail 48— 49 cm (males) and 44-49 cm (females); weight unknown, but probably 1000-1500 g as for other members of the torquatus species group. Male and female Rio Jurua Collared Titis are indistinguishable in size and coloration. They are predominantly brown or blackish, with some banding of hairs on their backs and sides. Hands are orange. Inner sides of arms are entirely blackish, and feet are black. Tail is blackish. Throat collar is a distinct white, extending upward to ears. Sideburns are brownish, and hairs above and behind ears are more or less banded. There is a distinct reddish crown.
Habitat. Lowland Amazon rainforest at elevations of 100-200 m.
Food and Feeding. There is no information available for this species.
Breeding. There is no specific information available for this species, but all titis form monogamous breeding pairs. The male provides parental care by carrying the single offspring.
Activity patterns. There is no information available for this species.
Movements, Home range and Social organization. There is no information available for this species.
Status and Conservation. CITES Appendix II. Classified as Least Concern on The [UCN Red List. The region where the Rio Jurua Collared Titi occurs is isolated and suffers little anthropogenic impact. It is found in Rio Bia and Vale do Javari indigenous reservations and may also occur in Jutai-Solimoes Ecological Reserve.
