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.
