Mycale (Mycale) incurvata Lévi, 1993 Mycale incurvata Lévi, 1993: 35, pl. 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.).
