Holothuria (Roweothuria)

Thandar, 1988

3 species

Cylindrical to subcylindrical species up to 220 mm long. Tentacles (19) 20. Podia either in the form of papillae only or papillae dorsally and pedicels ventrally, the former scattered or in rows, often accompanied by conical warts bearing other minute papillae; pedicels, if present, crowded but not forming a sole. Calcareous ring stout, radial plates with a median ampullary notch and twice as high as interradial plates, the latter with an anterior, tooth-like median projection. Spicules consisting of tables and buttons. Tables clumsy, the spire low to moderate, terminating in a ring or cluster of teeth, often giving the appearance of a maltese cross when viewed from above; disc well developed and spinose, rarely some discs smooth, rim flat, not turned up to give cup and saucer appearance to table in lateral view. Buttons rosette-like, smooth to rugose or spinose, with 1-6 pairs of holes, sometimes incomplete or twisted or with rudimentary knobs. (Thandar, 1988)
