(total): 6 - 7;
soft rays: 10. Characterized by brownish grey color; head and base of pectoral fin with numerous short blue oblique lines; 4-5 diffuse dark bars on side; anal fin with grey and yellow stripes; united pelvic fins, presence of frenum; longitudinal scale series 110; head without scales; greatest depth of body about 5.6 in SL; oblong caudal fin, slightly longer than head length (Ref. 90102).
Found on fine sand bottoms in protected areas (Ref. 34765). A pair shares a burrow with a Alpheus sp. (Ref. 34765). Inhabits protected fine-sand lagoons or bays in 2-12 depth range (Ref. 48637). Also found in silty coastal reefs, often in turbid water with poor visibility (Ref 90102).
