The Araripe manakin (Antilophia bokermanni) is a critically endangered bird from the family of manakins (Pipridae). It was discovered in 1996 and scientifically described in 1998. The species epithet commemorates Brazilian zoologist and wildlife filmmaker Werner Bokermann, who died in 1995. Because of its helmet-like crown it has received the Portuguese name soldadinho-do-araripe which means "little soldier of Araripe". This name also associates it with the related, but more widespread, helmeted manakin (Antilophia galeata), which is known simply as the soldadinho.
As typical of most manakins, males and females have a strong sexual dimorphism in the colors of the plumage. As in the helmeted manakin, it is a relatively large and long-tailed manakin, with a total length of c. 14.5 centimetres. The strikingly patterned males have a predominantly white plumage. With the exception of the white wing coverts, the wings are black as the tail. From the frontal tuft, over the crown, down to the middle back runs a carmine red patch. The iris is red. The females are mainly olive green and have pale green upperparts. They have a reduced olive green frontal tuft.
This species is endemic to the Chapada do Araripe (Araripe uplands) in the Brazilian state of Ceará in the north eastern region of the country. It is only fifty kilometres long and one kilometre wide and the typical habitat apparently is a consequence of the soils formed from the Early Cretaceous Santana Formation limestone. The pure breeding range has a size of only 1 km² and lies in a theme park. It is likely to be more widespread than presently known, although surveys in nearby Balneario das Caldas failed to locate any individuals.
In 2000 there was an estimated population of less than 50 individuals and it was considered as one of the rarest birds in Brazil and in the world. Only three males and one female were found until that date. In 2003 the estimations were more optimistic and BirdLife International assumed the population of 49 to 250 individuals. In 2004 it proceeded on the assumption that less than 250 individuals exist in the wild which was based on 43 discovered males. In 2000 a theme park with swimming pools and asphalted roads was built at the type locality Nascente do Farias and the largest part of its original habitat became destroyed. The cleared trees were replaced by banana plantations.
