soft rays: 7;
Vertebrae: 26. Diagnosed from all other species of the genus Rhinogobius by the unique combination of the following characters: second dorsal fin with one spine and 8 rays; anal fin with one spine and 7 rays; pectoral fin with 16-17 rays; scale on longitudinal series 28-30; predorsal scales 3-5; vertebrae 26; body side with 6 clusters of blackish-brown marks in male, grayish-brown in female; scale pockets of lateral body with conspicuous deep brown margin in female but not distinct in male; caudal fin base with a median black spot; snout with a dorsal pair of broad bright red stripes; a lateral pair of broad bright red stripe below orbit reaching vertically to corner of upper lip; snout orange; cheek with 2 oblique, parallel deep brown lines in male but absent n female; branchiostegal membrane grayish brown with 9-10 rounded bright orange red spots in male but uniform grayish and spotless in female; first dorsal fin with broad median grayish-black band; basal region of pectoral fin grayish black with basal, semicircular creamy-yellow region in male, pale in female (Ref. 79879).
Inhabits shallow riffles with depth 30-60 cm, substratum composed of large pebbles and moderate to fast flowing water (Ref. 79879).
