Description
Dorsal spines (total): 6-7; Second dorsal fin spine: 1; Dorsal soft rays: 11-12 (usually: 12); Anal spine: 1; Anal soft rays: 11-12 (usually: 12); Pectoral fin rays: 19-22 (usually: 20-21); Lateral scale series: 70-88; Body depth: 5.0-5.5 in SL. Transverse rows of scales backwards: 19-25; Fish without filamentous dorsal spines; Rounded caudal fin, equal or slightly shorter than head; Ctenoid body scales, becoming cycloid anteriorly in front of first dorsal fin; Head or midline of nape without scales; Side of nape with scales extending forward slightly anterior to opening of gill; Pectoral fin base and prepelvic area usually fully scaled. First dorsal fin rounded. Max. length: 9.1 cm SL. Depth range: 5 - 88 m, usually: 5 - 25 m.
Color
Head and body pale grey to pearly white, with 3 brown dark-margined bars on body and similar bar across distal half of caudal fin; Oblique iridescent blue-white stripe on sides of head below eyes; large black spot on rear of first dorsal fin, and 2 black bars on lower part of second dorsal fin (continuous with those on body).
Etymology
Valenciennea: in honnor of Achille Valenciennes (1794-1865) who was a French zoologist. He worked with Auguste Henri André Duméril (1812-1870), Georges Cuvier (1769-1832) and Bernard Germain de Lacépède (1756-1825) since 1815. He worked on the 22-volume of a "Histoire naturelle des poissons" (1828-1848), carrying on alone after Georges Cuvier died in 1832.
wardii: in honor of British diplomat Swinburne Ward (1830-1897), Her Majesty’s Civil Commissioner for the Seychelles (even though this goby was described from Zanzibar, Tanzania).
