Distribution	North Direction Island, Great Barrier Reef, Queensland. Elsewhere the species occurs in the Ryukyu Islands, Japan, and Palau. This species is commensal in branching corals, especially Pocillopora eydouxi, in bays at the reef edge, or on the reef slope at depths of 2–16 m. The species also occurs in the branching coral, Stylophora pistillata.

Origin of first dorsal fin posterior to the upper pectoral-fin base, origin of pelvic fins directly below the lower pectoral-fin base. Scales ctenoid, absent from head, nape, prepectoral and prepelvic regions, midventral abdomen, and along base of dorsal and anal fins.
Remarks	Use of the name Paragobiodon kasaii in Australia is tentative, as Australian specimens have three colour phases rather than the two for P. kasaii.
Etymology	The species us named in honour of Mr. Masao Kasai, who first discovered the new species and photographed it underwater.
