(2015) provided detailed morphological reasons for recognising the genus. Gobius sublitus Cantor, 1849 . The species was described from Malaysia . The holotype is a varnished skin and clearly has a lappet over the eye and a broad gill opening indicating Psammogobius . Two species are being confused under the name Psammogobius biocellatus : P. biocellatus with opercular scales and fully scaled predorsal and a second species without opercular scales and reduced predorsal scales. The second species probably has a name, but we have not examined sufficient type material to be sure of the appropriate name. Psammogobius biocellatus is known from the Indian Ocean and western Pacific, but the second species is only known from the western and central Pacific.
