Description
Body ground colour white, with the outer margin of the mantle edged by a thick red band. The red band sends a series of irregular tooth-like prolongations inward and forms a strongly undulate, wave-like pattern, indenting deeply toward the centre of the dorsum; the indented central area takes on a yellowish tone. A fine opaque white thread runs along the inner border of the red band. Rhinophores have a translucent white stalk and a black club; the gills are also tinged black. Reaches up to 30 mm in length.Distribution
Type locality: Ceylon (present-day Sri Lanka). Widely distributed across the tropical Indo-West Pacific and central Pacific, with records from the Red Sea, Madagascar, the Maldives, Australia, the Philippines, New Caledonia, Japan, Guam, and Palmyra Atoll.Etymology
The specific epithet fidelis is Latin for "faithful" or "loyal."Remarks
