N. tupecomareni sp. nov.: J, transverse section showing skeletal architecture near surface (J', detail of ectosomal region highlighting abundance of spinorhabds); K, megascleres; L, detail of extremities of both megascleres in K; M–P, large spinorhabds; Q, small spinorhabds. M. (B.) araucana sp. nov.: R, transverse section showing choanosomal skeletal architecture; S, choanosomal style; T, ectosomal subtylote; U, details of extremities of ectosomal subtylote; V, anchorate isochelae. Scale bars: A, S, 100 µm; B, D, F, J', T, 50 µm; C, E, G, H, U, 5 µm; L, 10 µm; J, 800 µm; R, 200 µm; M–Q, V, W, X, 20 µm.
