Coimbra Filho's titi Coimbra Filho's titi Coimbra Filho's titi ("Callicebus coimbrai") or just Coimbra's titi is a species of titi, a type of New World monkey, endemic to forests in the Brazilian states of Bahia and Sergipe. It was first discovered by Shuji Kobayashi. It is considered one of the most endangered of all Neotropical primates. It is named after Adelmar F. Coimbra-Filho, founder and Former Director of the Rio de Janeiro Primate Centre, in honor of his work in the field of Brazilian primatology and biology. The most distinct of Coimbra Filho's titi's features, from other members of the "personatus" group, include
Coimbra Filho's titi fragment of the population, limiting reproductive options. The species' natural geographical distribution also contributes a threat to the species. Coimbra Filho's titi only naturally occurs in the Atlantic coastal forests in northeastern Brazil. This is a relatively small area in the states of Sergipe and Bahia. Due to this small range, any disturbances to these areas pose a larger than normal threat to the species' survival. More than anything else, however, human interference is the source of many problems to Coimbra Filho's titi. The areas around and inside its habitat are being developed, including paving roads and the promotion of
