Schismatogobius fuligimentus is a species of freshwater goby endemic to New Caledonia, where it is found in shallow, slow-moving streams with gravel substrates at altitudes up to 250 m (820 ft), although it is suspected of being amphidromous.

Males of this species can reach a standard length of 2.9 cm (1.1 in), while females can reach 3.8 cm (1.5 in).

[2] It is a slender, generally cylindrical goby.

It is generally yellow with brown or black markings and displays sexual dimorphism; the underside of the head is yellow in males, black in females.

It can be distinguished from all its congeners by having a lower number (13 or 14) of rays in the pectoral fins.
