Similar in externals shape and morphology to Cadlinella ornatissima with a interwoven network of spicules throughout the mantle and body wall. There are many elongate round-tipped tubercles scattered all over the mantle, muchlarere and more elongate than in C. ornatissima. The mantle glands see to be restricted to small spherical sacs forming a broad band around the mantle edge. Although the general colour of the two species is similar, in C. subornatissima the yellow background colour is restricted to the central part of the mantle, there being a broad colourless band around the edge of the mantle skirt. Another difference is that there is broad basal colourless patch around each tubercle in C. subornatissima, while in C. ornatissima the yellow background colour extends right up to the base of each tubercle.
