EtymologyThe specific epithet ‘‘surucucu’’ is derived from Tupi indigenous name (suú-u-u) meaning a very aggressive pit-viper. This is used here as noun in apposition, alluding to the proper name of the type locality of the new species (Serra do Surucucu). Surucucu refers also commonly to the popular name of the Bushmaster Lachesis muta in Brazil.
