Range DescriptionEndemic to Brazil, the Blond Titi Monkey occurs in the states of Bahia (Hershkovitz 1990) and Sergipe at approximately 240-900 m asl (Printes 2007) from the Rio Paraguaçu river basin to the border between the states of Bahia and Sergipe along the margins of the Rio Real. Prior to the survey of Printes (2005, 2007), this species was known from only four localities: Lamarão (type locality), Formosa, Bandeira de Melo and Mirorós in the municipality of Ibipeba all in the State of Bahia (Hershkovitz 1990; Marinho-Filho and Veríssimo 1997). However, the taxon has now been confirmed at over 55 sites in Bahia and Sergipe (Printes 2007; Estrela et al. 2007). In recent surveys (195 km) undertaken in Lamarão in Bahia, the species was registered in four locations, all caatinga scrubland fragments (Estrela et al. 2007), some considerably smaller than previously estimated (A. Estrela pers. comm.). In the past, the coastal forests of the ‘Agreste’ in eastern Bahia probably supported large populations; however, this type of vegetation is rare today (Printes et al. in prep.). Populations have been located in three main regions: Agreste, Lamarão and north of the Chapada Diamantina. No titis were recorded in the region west of Araci and Nova Soure, which is dominated by the Cerrado. However, C. barbarabrownae was recorded in the Caatinga of the moister uplands northeast of Araci (Mandacaru, Mirandela and Serra Branca). The species was also recorded in Caatinga habitat further north as far as the Salitre river, 170 km from Juazeiro, but titis were not recorded west of the Chapada Diamantina (Printes 2007; Printes et al. in prep.)
Callicebus melanochir replaces C. barbarabrownae in the region known as the ‘Recôncavo Baiano’ (south of the Paraguaçu river in the municipality of Igrapiuna). The lower Paraguaçu forms the limit between the geographic ranges of C. coimbrai, restricted to the left or north bank, and C. melanochir, found on the right bank. Further west, in the region of Feira de Santana, C. barbarabrownae occurs on both banks of the Paraguaçu. There appears to be no physical barrier between the eastern limit of the range of C. barbarabrownae and the western limit of C. coimbrai (Printes et al. in prep.).
The extent of occurrence of the Blond Titi Monkey is estimated to cover an area of some 291,438 km², but its area of occupancy is only thought to be 2,636 km² (Printes 2007; Printes et al. in prep.). Approximately 90% of all records are between 37º and 41ºW and 09º and 13ºS (Printes 2007).
