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.

[2] The headspot eviota has been documented only in Australia; records of the fish elsewhere are thought to be misidentifications.

[5] The headspot eviota is a small-sized fish, growing up to 30 millimetres (1.2 in) length.

[6] 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.
