; colour off-white. Mouth ventral, tentacles about 20; anus sub-ventral. Encrustations include sand grains, broken shells, coral debris, echinoid spines and foraminifera but no pteropod shells or sponge spicules. Podia thin, mostly on dorso-lateral radii. Polian vesicle single. Ossicles only in tentacles, podia, respiratory trees and gonad. Tentacle and podial ossicles as slender, curved rods with mostly spinulated, rarely branched, sometimes perforated ends. Gonad and respiratory tree ossicles mostly as x- or y-shaped rods with central thickening and tapering branches, sometimes straight, c- or s-shaped bodies, sometimes irregularly branched. Pygal lobes without deposits.

A) delicate, radial plates sculptured, each with an anterior notch and a concave posterior margin; interradial plates also slightly sculptured with a shallow posterior concavity and an anterior tooth-like projection with the tooth lying in the middle of paired ridges. Polian vesicle single, sac-like; stone canal not detected. Gonad (testis) as tuft of unbranched tubules arranged serially along entire length of stolon. Longitudinal muscles thick, partially paired, folded, appearing cylindrical. Respiratory trees well branched, yellowish, one longer than the other, but reaching only anterior third of body. Stomach filled with foraminifera, sand grains, coral debris, etc.

The distinguishing features of the new species are the presence of characteristically branched x- and y-shaped rods with central thickening and tapering branches in the gonad and respiratory trees, the absence of sponge spicules and pteropod shells in its encrustations, and the absence of papillae or tuberosities on the body wall, ossicles in the pygal lobes and end-plates in the podia.
