Coimbra’s Titi
Callicebus coimbrai Kobayashi and Langguth, 1999
CR B1ab(i,ii,iii); C2a(i); D

This new species of titi was found in 1994, south of the Rio São Francisco in the Atlantic coastal forests of the northeastern Brazilian state of Sergipe. It was named in honor of Dr. Adelmar Coimbra-Filho, founder and former director of the Rio de Janeiro Primate Center, in recognition of his contributions to the biology and conservation of Brazilian primates. The limits of this titi’s range remain unknown, but it is believed to be restricted to a very few humid coastal forest fragments, and to be replaced in the drier inland forests by Callicebus barbarabrownae. Due to its limited distribution, the widespread destruction of forests that has occurred in this region, and the fact that it is not known to occur in any protected area, Coimbra’s titi is considered critically endangered.
