Identification

The Cheekspot Scorpionfish can be distinguished from other Australian east coast scorpionfishes by the dark blotch on the operculum and the red-spotted fins. It has small ctenoid scales and thirteen venomous dorsal fin spines. There are small leaf-like appendages on the head and mouth. Its colouration is variable from brown to pink or red.

In many publications, the Cheekspot Scorpionfish has been recorded as the Pygmy Scorpionfish, Scorpaenodes scaber. The two species look very similar, but the Pygmy Scorpionfish lacks a dark spot on the operculum.  It is only known from the two type specimens in the Australian Museum Ichthyology Collection that were collected collected in Port Jackson (Sydney Harbour), New South Wales in 1885.

The species has also been called Scorpaenodes littoralis in many publications.  The 2010 publication of Motomura et al showed that S. littoralis is a junior synonym of S. evides.

Size range

The species grows to 10 cm in length.

Distribution

The species occurs in the Indo-West and Central Pacific.  In Australia it is known from the central coast of Western Australia, around the tropical north of the country and south to the southern coast of New South Wales.
