The middle Palaeocene of São José de ltaboraí (State of Rio de Janeiro, Brazil) has produced a rich and diverse fauna of boid snakes. It comprises six or seven species: Hechtophis austrinus gen. et sp. nov., Corallus priscus sp. nov., Waincophís pressulus sp. nov., Waincophis cameratus sp. nov.,"Boinae A", and "Boinae B". Moreover, two dentaries might pertain to either H. austrinus or "Boinae B", or even represent a distinct taxon. Hechtophis austrinus is assigned, with reservation, to the Erycinae. All other taxa are referred to the Boinae. The vertebrae of all taxa have paracotylar foramina, which raises the problem of the apomorphic or plesiomorphic nature of this feature. This fauna also raises the question of the presence of extinct erycine boids in South America, but it does not allow this question to be settled.
