Diagnosis. A species of Johnius with the following combination of characters: snout steep, obtusely rounded, slightly projecting in front of upper jaw; mouth small, inferior; lower jaw with a band of villiform teeth; gill rakers very short, club-shaped, less than 1/2 length of gill filaments at angle of arch, 8 to 10 on lower limb of first gill arch; second spine long, stiff, 31 to 45% of head length; and scales moderately small, 7 to 11 scale rows above lateral line to origin of dorsal fin, 12 to 17 scale rows below lateral line to origin of anal fin (Hanafi et al., 2023). Distribution. Indo-West Pacific, west to the Persian Gulf, east to southern China and Indonesia. Remarks. Johnius belangerii is a common species distribute in the East Malaysian waters, also in the Taiwanese waters (Hanafi et al. 2023). It was abundantly collected from several sites off the Sarawak states, but few in Sabah states. This might due to ecological sandy and muddy area distribution available for this species to distribute. The variation in the shape band pattern observed in this species throughout collection sites implies it is a morphologically complex species (Hanafi et al., 2023).
