DiagnosisHutchinson (1990) considered a diagnosis of the genus Cacophis problematic, and recognized it only 'tentatively' as distinct from Furina. Cacophis species are small nocturnal saurophagous (lizard-eating) snakes, all restricted to rainforest or wet sclerophyll habitats in coastal regions of eastern Australia (Queensland and New South Wales).

A (rather extensive) diagnosis of the genus can be found in Scanlon (2003).

Diagnosis (species): Scanlon 2003: 14. 
CommentSynonymy partly after COGGER 1983.

Type species: Cacophis krefftii GÜNTHER 1863 is the type species of the genus Cacophis GÜNTHER 1863.

EtymologyNamed after Gerhard Krefft (1830-1881), German-born naturalist who worked mostly in Australia.
