Chaetomys subspinosus (bristle-spined rat)

Wikipedia Abstract

The bristle-spined rat (Chaetomys subspinosus) is an arboreal rodent from 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. 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.
