General ground color ultramarine blue; a median stripe of pale blue extends from between the rhinophores to just anterior of branchial plumes and continues for a short distance just posterior of branchial plumes; a similar stripe occurs dorso-medially on posterior portion of foot which extends beyond dorsum. A stripe of yellow-orange extends longitudinally on either side of dorsum from just posterior of rhinophores to posterior of branchial plumes, where the stripes meet; a line of similar color forms an arc just anterior of rhinophores. Dorsum edged with a narrow, white line. Rhinophores darker blue than dorsum, with 12-14 lamellae. Branchial plumes 9-12, unipinnate, ultramarine blue. Labial tentacles conical to short digitiform. May be distinguished from Felimida macfarlandi which is more purple in color, and has a longitudinal yellow stripe medially on dorsum.
Up to about 35mm in length.
Monterey Bay, CA, to Bahía Tortugas, Baja California, Mexico.
Found in the low rocky intertidal, and subtidal to 18 meters. Extremely rare in Monterey Bay area, I've seen only 3 individuals in 48 years.
