Austrocidaria cedrinodes is a species of moth of the family Geometridae. It was first described by Edward Meyrick in 1911. This species is endemic to New Zealand and has been observed in the North, South and Stewart Islands. Although widespread across the country A. cedrinodes is regarded as being a scarce species. It inhabits open native scrubland populated with species of Leptospermum, Dracophyllum as well as species in the genus Coprosma. This latter genus contains the larval host plants of A. cedrinodes. Adults are on the wing commonly from September until February and are nocturnal and attracted to light.
