Etymology: Cambeva: Probably derived from the Tupi-Guarani, is a popular name for trichomycterid fishes in southern and south-eastern Brazil (Ref. 119381); damnata: Name 'damnata' from the Latin word meaning 'condemned', in reference to the risks that the species faces with the plans for mining activities at the Serra do Curral and urban expansion.
