Thelonota

Brandt, 1835

3 species

Tentacles 20, Ventrum flat with numerous ordinary pedicels. Dorsum convex, closely beset with papillae. These look forward in the anterior, backward in the posterior and are mostly united two by two at the base. In the rest of the dorsum, 3-8 papillae joined at the base, together form stellate figures like the petals of an open flower. In the interval between these composite papillae, are smaller ones. Calcareous deposits are dichotomously branched, slender pointed X-shaped spicules and aggregations of innumerable minute grains. (Mitsukuri, 1912)

Dorsal papillae united into complex leaflike structures. (Deichmann, 1958)

Large stichopodid holothurians with a single long, branched polian vesicle; body wall spicules as dichotomously branched, slender rods and minute miliary granules. (Thandar, 1987)
