Type data: EcHh 586; Suez; coll. M. Letourneux, 1880; unknown depth; well preserved; poorly relaxed; ventro-longitudinal dissection.

Anatomical description: 145 mm long; 30-35 mm wide; bivium arched; trivium flattened; dorsal body wall clear beige to clear brown; ventral body wall white-beige; tentacle colour uniform beige; dorsal appendages brownish; ventral tube feet yellowish; dorsal and ventral tube feet dispersed all over surface; bivium and trivium separated by a prominent lateral fringe of appendages; body wall rough to the touch; body wall <1 mm thick; tentacles small, 20 counted; calcareous ring with quadrangular radial plates with slightly indented posterior side; interradial plates as wide as radial ones; radial plates up to twice as long as interradial ones; 20 small tentacle ampullae counted; number of Polian vesicles could not be determined; single stone canal observed; gonad not observed; longitudinal muscles bifid, wide and free at edges; Cuvierian tubules not observed.

Ossicle description: tentacles with rods of various sizes; large ones stout, rugose and perforated; dorsal body wall with tables with spiny disc perforated by 2-4 central holes and 0-1 ring of peripheral holes, with low spire ending in a spiny crown, very rugose buttons perforated with 4-6 pairs of holes; ventral body wall with very few tables and numerous rugose buttons perforated by 3-7 pairs of perforations; dorsal appendages with tables similar to those of body wall, elongated rugose buttons and rods perforated and widened distally and centrally; anal papillae with curved smooth, distally branching rods and button-like rods; longitudinal muscles of longitudinal and cloacal retractor muscles devoid of ossicles; ossicle assemblage of ventral tube feet, gonad, cloaca, respirartory tree, gut and rete mirabile was not assessed.

Holothuria (Cystipus) mammosa Cherbonnier, 1988: 123, fig. 50A-Q; Samyn, 2003: 30, 35.

Type data: EcHh 3550; Nossi-Bé, Ambaro Bay (Madagascar); coll. Crosnier, 4.XII.1964; 24 m depth; well preserved; well relaxed; eviscerated; dorso-longitudinal dissection.

Anatomical description: 68 mm long; 18-43 mm wide; morphology of the bivium and the trivium could not be assessed; dorsal body wall beige-grey; ventral body wall white-yellow; tentacle colour beige; dorsal appendages beige; arrangement of tube feet could not be assesd on bivium and on trivium; bivium and trivium not separated by a lateral fringe of appendages; body wall rough to the touch; body wall 1.5 mm thick; tentacles small, number could not be determined; calcareous ring with quadrangular radial plates with straight posterior side; intrradial plates two times narrower and three times shorter than radial ones; structure and number of tentacle ampullae not assessed; number of Polian vesicles could not be determined; number of stone canals could not be determined; gonad not assessed; longitudinal muscles bifid, wide and attached at edges; Cuvierian tubules not observed.

Ossicle description: tentacles with straight, unbranched, slightly spined rods; dorsal body wall with tables with round very nodulous disc with low spire ending in a nodulous crown and with nodulous buttons with generally three pairs of holes; ventral body wall with tables with round nodulous disc and low spire ending in a narrow crown and with nodulous buttons perforated with 3 pairs of perforations; ventral tube feet with morula-like tables, very small nodulous buttons and plates; cloaca and cloacal retractor muscles with distally perforated rods;longitudinal muscles devoid of ossicles; ossicle assemblage of dorsal appendages, gonad, rete mirabile and gut was not assessed.

Known distribution: known only from the type locality (Tuléar, Madagscar).

Taxonomic decision: valid species (confirmed after re-examination of the holotype).

Remarks: no tissue was taken from the dorsal papillae, but the typical large and very nodulous tables and plates can be found on the picture of the dorsal body wall.
