Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 10; Épines anales: 1; Rayons mous anaux: 9; Vertèbres: 26. This species is distinguished by the following set of characters: D VI, I,10; A I,9-10; naked head and majority of body, with some squamation on caudal peduncle; body slightly laterally compressed (body depth at pelvic-fin origin 40.6-45.3% SL), typically dorsal ventrally symmetrical, rounded head; small mouth with pronounced recurved lips; presence of groove between isthmus and interopercle; relatively deep caudal peduncle (15.5-18.6% SL); long caudal fin (22.1-29.3% of SL); absence of post symphysial teeth, triangular dentary with various sizes of jaw dentition; elongate cheek papillae length exceeding width; blue-green base colouration and red markings on the face and body of adults; facial markings as vertical bars on cheek, small spots on dorsal surface of head and unbroken horizontal lines along the length of the body beginning post pectoral fin (Ref. 133118).
Cross section: compressed.
Facultative air-breathing in the genus; Gobiodon bicalvolineatus inhabits the branching coral of Acropora caroliniana (Ref. 133118).
