III fig. 7, text-fig. 12. Summary description . Shape hollow-flabelliform, size 7 x 4 x 2.5 cm . Surface provided with a system of intercrossing grooves and ridges. Color greenish yellow-grey. Ectosomal skeleton not described but presumably tangential, carried by bouquets of the choanosomal plumoreticulate spicule tracts. ‘Pseudorosettes’ of anisochelae I are fixed to the subectosomal spicule tracts. Spicules mycalostyles 400–590 x 12–15 µm , anisochelae I 100 µm , anisochelae II 38–48 µm , anisochelae III 20–22 µm (not spurred). Distribution . New Caledonia , depth 680–700 µm . Comment . The species is unique in the region considered in lacking both sigmas and trichodragmas, shared only with M. (M.) trichela from the Atlantic coasts of South Africa . It is otherwise closest to M. (M.) asigmata sp.nov. and M. (M.) myriasclera (cf. above in the Remarks of M. (M.) asigmata sp.nov . ).
