Distinguished by the following characters: mouth moderate; reaching to a point below anterior margin to middle of eye; operculum with a small patch of 10-20 scales dorsally in 2-3 longitudinal rows; second dorsal rays I,8; pectoral rays 18-21 (usually 19 or 20); predorsal scale count 15-19; one or usually two small lateral canal head pores above anterior operculum just before terminal lateral canal pore; papilla line 6 well developed; papilla lines composed of a single row of papillae; snout length 11.6-13.6% SL ; body with 5 oval, horizontally elongate brown to black spots on midside from second dorsal origin to posterior end of caudal peduncle; spots usually bordered by faint brown lines above and below.
Adults live in clear streams, usually close to the sea (Ref. 5259). They occur mainly in fresh water, but larvae in marine environment (Ref. 5259).
