It has a translucent body wall, is pinkish white in colour and densely covered with sponge spicules and some other encrustations. Its tentacles are minute and could not be counted and the distribution of its minute tube feet could not be determined. The pygal furrow, if at all present, is inconspicuous. The calcareous ring is well developed with broad anteriorly notched radial plates. There are no ossicles in the body wall and other organs. Therefore, whether the specimen represents a Pseudostichopus or another genus is debatable. O’Loughlin & Ahearn (2005) list only two species with a dense mat of sponge spicules, viz. P. hyalegerus (Sluiter, 1901) and P. spiculiferus (O’Loughlin, 2002). However, the first is a West Pacific form with ossicles in the papillae and pygal lobes and the latter is an Antarctic form with ossicles in the gonad. Hence more material is required for both generic and specific determination.
