Eviota melasma, commonly called headspot eviota or melasma pygmy goby among various other vernacular names, is a species of marine fish in the family Gobiidae.[1]
The headspot eviota has been documented only in Australia; records of the fish elsewhere are thought to be misidentifications.[2] The fish is found on offshore reefs and coastal reefs,[3] just below the tidal zone.
The headspot eviota is a small-sized fish, growing up to length.[4] It is a semi-transparent pygmy goby marked with irregular rufous internal bars along the length of its body, with a black spot above the opening of the gills, irregular reddish blotches on its nape, and three reddish blotches which are separated by whitish barring on the belly. It also has a thin white stripe at the base of the pectoral fin.[3]
