Hickman, 1962

2 species

Dendrochirote holothurians with 25 tentacles arranged in two circles. Pedicels on radii but lacking on interradii. The pedicels extend onto the introvert. Calcareous ring simple without posterior bipartite prolongations. The interradialia somewhat reduced. In adults, the calcareous bodies or spicules are few and widely scattered in the body wall, where they have the form of perforated plates without towers or spires. Spicules are absent from the pedicels except for the end plate. (Hickman, 1962)
