--------------------------
Description
Dorsal spines (total): 7, first and second dorsal spines greatly prolonged as a broad filament, the second longer, generally more than 1/2 standard length; Dorsal soft rays (total): 10-11 (usually: 11); Anal spines: 1; Anal soft rays: 10-11 (usually: 11); Body depth: 4.3-5.2 in SL; Head length: 2.95-3.15 in SL. Pectoral fin rays: 18-20; Longitudinal scale series: 47-51; No scales on head, chest, nor nape except for a few oblique rows of small scales anterior to upper end of gill opening; Scales cycloid anteriorly on body, ctenoid dorsally on body posterior to 4th or 5th dorsal fin; Gill opening extending forward to a vertical at posterior margin of eye; Caudal fin rounded except middle 5 or 6 rays of equal length (so fin margin straight in central part), fin length about equal to head length; Pelvic fins nearly or just reaching anal-fin origin. Max. length: 6.0 cm TL. Depth range: 4 - 40 m, usually: 15 - 40 m.
Color
Body translucent light gray with a midlateral row of five orange-yellow spots nearly as large as pupil; Other smaller orange-yellow spots, white spots, and a scattering of pale blue dots on body; Head with two oblique dark-edged yellow lines behind eye, the upper continuing as a series of dashes to origin of first dorsal fin; Small dark-edged orange-yellow spots on cheek and opercle, the darkest (may be mainly black) behind corner of mouth; Membrane between first and second dorsal spines blackish; A long narrow white streak on lower 1/3 of pectoral fins (white spot or short dash in other species of the genus).
Etymology
Ctenogobiops: from Greek, kteis, ktenos = comb + from Latin, gobius = gudgeon + from Ancient Greek, óps = eye, face, appearance. Referring to the closely related and presumably similar to Ctenogobius genus.
tangaroai: from Tangaroa, is one of the main deities of the Pacific Islands. often revered as a god of the sea, he represents, in Tahiti and on other archipelagos like those of Samoa, Tonga and Tuvalu, the creator of the Universe and all its inhabitants.

Distribution
Western Pacific: Indonesia, east to Palau, Guam, Fiji, Tonga and Samoa, north to Ryukyu Islands (Japan), south to northern Australia and New Caledonia.
