VII fig. 6, text-fig. 17. Material examined . MNHN DCl 2966, holotype , New Caledonia , Banc de la Torche , 300 m depth . Summary description . Semiglobular, yellow-ochraceous, firm mass, size 3 x 2.5 x 1.5 cm . Surface smooth formed by a thick ectosomal skeleton of tangential megascleres. Choanosomal skeleton consisting of thick megasclere tracts dividing dichotomously in the subectosomal region carrying the ectosomal region. Rosettes of anisochelae I and also of anisochelae II are found in the ectosomal region. Spicules: mycalostyles 750–900 µm , strongly curved anisochelae I with broad short upper alae 85–90 µm , anisochelae II 20–25 µm , trichodragmas/raphides 120 µm , the latter occurring in dense masses. Distribution . New Caledonia , deep water. Comment . Because of the shape of the anisochelae I, the present species appears closely related to Mycale (Mycale) dendyi , but that has anisochelae III, sigmas, and the mycalostyles are distinctly smaller.
