Description
Dorsal fin rays (branched and unbranched): 10-12 (usually: 11); Anal fin rays: 9; Pectoral fin rays: 11-12 (usually: 12); Pored lateral-line scales: 54-55 (usually: 54). Body tubular, head somewhat depressed, caudal region a little compressed. Large cycloid scales on body, extending onto cheeks and opercule; 5 rows of large cheek scales entirely covering cheeks. Snout pointed, broader than long; anterior nostrils on each side bearing a long leaflike flap on its posterior margin extending well beyond edge of nares when depressed anteriorly. Adipose eyelid narrow. Interorbital space very narrow and concave, occipital region bony, smooth, with 3 bony ridges radiating from behind each eye. A single row of forwardly directed teeth in each jaw and 1 or 2 rows of smaller teeth set below level of lips. Palatine teeth in an elongate V-shaped pad, in 2 rows, teeth backwardly pointing, those in front not longer than others. Lingual teeth large and slightly recurved, in 3 rows. Teeth in jaws, palatines and tongue caniniform, larger teeth with arrowshaped tips. Pectoral fins short, not reaching to a line from base of pelvic fin to origin of dorsal fin. Outer pelvic ray unbranched and short, the fifth branched ray longest, reaching beyond a vertical from posterior base of the dorsal fin. Posterior bony processes of pelvic girdle short, broad. Peritoneal color pale, whitish with 11-12 black spots along each side of body wall. Max. length: 20.0 cm TL. Depth range: 0 - 50 m.
Color
Body mottled with red. Five broad undulated bars extend from middorsal line down to lower half of sides, dark reddish on dorsum, paling to reddish brown on sides. Interspaces mottled with pale reddish brown, a large brownish blotch separating two pairs of whitish spots in interspaces on lower part of sides, the spots forming a horizontal row along either side of body. Ventral region pale, whitish. Head reddish brown, cheeks and occipital region bright red. Eye reddish, pupil red, edged with yellow. Fins with 4-5 narrow indistinct transverse reddish bands, adipose fin red.
Etymology
Synodus: from Greek prefix, syn- = identical, with, together, concomitant + from Greek, odous = teeth. For the single row of widely spaced teeth on upper jaw, more or less visible when the mouth is closed.
Rubromarmoratus: from Latin, rubeus, rubeo = red, reddish (color) + from Latin, marmoratus = marbled, covered or encrusted with marble, having been marbled, in reference to the characteristic red marbled coloration of the living fish.
