This species is distinguished from the other gobiine genera by the following set of characters: head and body deep and compressed; no crest-like dermal ridge along the predorsal midline;
no free pectoral-fin rays; head and predorsal midline are naked; a single transverse sensory-papillae row p at interorbital area over sensory canal between pores C and D; seven distinct and long transverse rows of sensory papillae (rows 1-7) below the eye where row b is long and extending from transverse row 3 to posterior margin of cheek, row 5 divided into two parts (viz., rows 5s and 5i) by longitudinal row b, and not extending beyond row d ventrally, row n (divided into two parts by anterior part of longitudinal row x1) transverse and very long, extending ventrally beyond a horizontal line through pore F, then row f comprised of a pair of short longitudinal rows of papillae; well-developed sensory canals on head, with pores B', C(S), D(S), E, F, G, H', K', L', M', N and O';l typical 'Bathygobius Group' (sensu Birdsong et al., 1988) type of axial skeletal features, e.g., P-V 3/II II I I 0/9; 10{1727 vertebrae; with two anal pterygiophores anterior to first haemal arch, and a single epural (Ref. 128872).
This species is found around the tidal estuaries and intertidal zone at or near the boundary between freshwater and brackish water areas of small insular streams with gravel bottoms and boulders. It is usually seen perched on large boulders, and nimbly skates on the surface of the boulders when disturbed (Ref. 128872).
