The bristle-spined rat (Chaetomys subspinosus) is an arboreal rodent from the Atlantic forest in eastern Brazil. Also known as the bristle-spined porcupine or thin-spined porcupine, it is the only member of the genus Chaetomys and the subfamily Chaetomyinae.[2] It was officially described in 1818, but rarely sighted since, until December 1986, when two specimens - one a pregnant female - were found in the vicinity of Valencia in Bahia.[3] Since then it has been recorded at several localities in eastern Brazil, from Sergipe to Espírito Santo (there are no recent records from Rio de Janeiro), but it remains rare and threatened due to habitat loss, poaching and roadkills.[4]
