Description. The holotype (Fig. 108 a) is a spiky mass of 2 x 1.5 x 1.5 cm, dark brown colored in preservation. It appears to have grown upon an unidentified ramose invertebrate, possibly a hydroid or bryozoan. The Seychelles specimen (Fig. 108 a 1) is a spiny, globular mass of beige color in life, lighter colored in preservation. Size 3.5 x 3.5 x 2.5 cm. Surface is flaky, irregular, without larger openings. The sponge grows between the branches of a ramose bryozoan and the composite specimen is compressible. The Indonesian specimen is tiny, encrusting on a piece of coral debris, sharing it with several other species, apparently yellowish colored in life. Very little material was retrieved from the sample. Skeleton (Figs 108 b – c). The main skeleton of the Seychelles specimen is carried by the branches of the ramose bryozoan and also some included masses of sand grains. The choanosomal skeleton (Fig. 108 b) consists of anastomosed spongin fibres cored by single or bundles of megascleres, in places the fibres are also filled with sand grains. The surface skeleton (Fig. 108 c) is free from foreign materials and also lacks spongin. It is an irregular layer of intercrossing single megascleres (reminding of subgenus Mycale) mixed with numerous rosettes of anisochelae I. The Indonesian specimen, contained in a thick section slide along with other sponge material, consists of thin spicule tracts connecting sand grains, with loose spicules and rosettes of anisochelae superimposed. Rosettes are 50 – 80 µm in diameter. Spicules (Figs 109 a – c). Mycalostyles, one category of anisochelae, one of sigmas. Mycalostyles (Figs 109 a, a 1 – a 6), ‘ cladotylostyle’ - like (see Thiele, 1903, p. 950), with one end with elongated head and constricted neck, the opposite end polyaxone (Fig. 109 a 1), with one (Fig. 109 a 3), two (Fig. 109 a 2), three (Fig. 108 a 4) or multiple (Fig. 109 a 5) bluntly or sharply pointed “ teeth’, occasionally without (Fig. 109 a 6) ‘ teeth’, but two-teethed forms are the most common, 183 – 290.6 – 378 x 2 – 4.3 – 7 µm. Anisochelae (Fig. 109 b), shaft curved and free part 35 – 40 % of spicule length, with well-developed upper and lower alae, upper median alae comparatively short and curved outward, 22 – 29.6 – 34 µm. Sigmas (Figs 109 c, c 1), comparatively narrow-shaped, asymmetrical, thickness 1 – 1.5 µm, with flattened spines on both endings, 51 – 65.8 – 87 µm.
