Bohadschia mitsioensis Cherbonnier, 1988: 38, fig. 12A-H; Samyn, 2003: 26.
Type data: EcHh 3545; North-East coast of Mitsio Id.(Madagascar); 40 m depth; coll. A. Crosnier; 15.II.1960; well preserved; poorly-relaxed; non-eviscerated; calcareous ring and associated structures removed from specimen.
Anatomical description: 153 mm long; 52-61 mm wide; morphology of bivium and trivium not discernable; mouth ventral; anus dorsal; dorsal body wall orange, mottled with white-yellow; ventral body wall uniform beige; tentacles with yellow to orange shaft and yellowish disc; dorsal appendages orange to brownish; ventral tube feet brownish; dorsal appendages spread regularly over bivium; ventral tube dispersed regularly over trivium; bivium and trivium not separated by lateral fringe of appendages; body wall 1-4 mm thick, smooth to the touch; number of tentacles could not be determined; radial plates with slightly indented posterior side; interradial plates narrower as radial ones; length radial plates 1.5 x longer than interradial ones; number of tentacle ampullae not determined; tentacle ampullae 18 mm long; Polian vesicle single, 12 mm long; stone canal(s) not observed; gonad with unramified tubules; longitudinal muscles bifid, wide, attached at edges; respiratory trees longer than half of body length; cloaca 35 mm long; Cuvierian tubules present.
Ossicle description: tentacles with smooth to slightly rough rods of various sizes; dorsal body wall with simple small granule-like rosettes; ventral body wall with simple, more open rosettes; ossicle assemblage of dorsal and ventral appendages could not be determined due to contraction of specimen; ossicle assemblage of anal papillae could not be determined; longitudinal muscles with simple rosettes; cloacal retractor muscles devoid of ossicles; cloaca with rosettes; respiratory trees with rosettes; gut devoid of ossicles
Known distribution: Mitsio Island (Madagascar).
Taxonomic decision: nomen inquirendum, comparison with the type material of B. marmorata Jaeger, 1833 needed.
Remarks: it is remarkable that the ossicles in the dorsal body wall are less complex than those in the ventral body wall because the reverse is generally true for Bohadschia spp. It is very possible that we made an inversion between the dorsal and ventral body wall when taking tissue (see also remarks with paratype).
