Crinia signifera and Crinia parinsignifera can look very similar, especially from the dorsal surface, and are much easier to differentiate based on their call. CS feature small, dark triangular patches on the upper lip, and a grey belly with white and black speckling or mottling. CP often have a dark triangular patch between the eyes, legs with dark horizontal bars, and cream-coloured bellies with several small light brown spots. Based on the cream-coloured belly I have suggested CP here, but it may also have dark lip patches, indicative of CS?
