611387AEFFD3FFD7FE83B8F9FC9EA443.taxon	diagnosis	Diagnosis. Massive sponges with a more­or­less collagenous rich cortex; triaenes often abundant, more rarely absent, oxeas and from one to three types of euasters, one of them confined to the choanosome, the other (s) sparse through the sponge. Occasional accessory ortho­ or trichodragmata. Microscleres may be lacking altogether (emended from Uriz, 2002 a).	en	Esteves, Eduardo L., Muricy, Guilherme (2005): A new species of Stelletta (Demospongiae, Astrophorida) without microscleres from Abrolhos Archipelago, northeastern Brazil.

611387AEFFD3FFD0FE83BA49FBCEA684.taxon	diagnosis	Diagnosis. Stelletta without microscleres, and with plagiotriaenes, anatriaenes and oxeas less than 590 m long. Clads of plagiotriaenes smaller than 70 m long and those of anatriaenes smaller than 20 m long. Anatriaenes with ill­formed and / or additional clads along the rhabdome are common.	en	Esteves, Eduardo L., Muricy, Guilherme (2005): A new species of Stelletta (Demospongiae, Astrophorida) without microscleres from Abrolhos Archipelago, northeastern Brazil.

611387AEFFD3FFD0FE83BA49FBCEA684.taxon	description	Description (Fig. 2 A). Thickly encrusting to sub­spherical sponge, 1.1 x 1.3 cm wide and 0.5 cm high to 1.4 x 1.9 cm wide and 0.8 cm high. Color pale beige in life and after fixation, both externally and internally. Oscules not evident. Sediment, mollusc valves and sea urchin spines are embedded in the surface of the body. Surface even, smooth or rough due to the presence of incorporated sediment debris. Consistency rather firm, slightly compressible. Internal anatomy. Ectosome with a distinct collagenous cortex (78 – 136 m thick). Oxeas rarely pierce the ectosome (Fig. 2 B). Small subdermal cavities (63 – 160 m in diameter) are abundant just below the cortex. Choanosomal skeleton formed by oxeas and anatriaenes disorganized at the inner part of the body, with ascending tracts of oxeas, anatriaenes and plagiotriaenes near the cortex (Fig. 2 B – C). Spherulous cells dispersed in great abundance throughout the choanosome, but absent in the cortex (Fig. 2 D). Spicules (Fig. 3, Table 1). Plagiotriaenes with straigth rhabdome, thickest underneath the cladome, sharply pointed: 210 ­ 360 ­ 491 / 2 ­ 6 ­ 9 m; cladome 23 ­ 58 ­ 95 m wide, with robust conical clads (Fig. 3 A): 10 ­ 34 ­ 63 / 2 ­ 5 ­ 8 m. Anatriaenes with the rhabdome straigth or slightly curved, conical or with a regular thickness along the shaft, sharply or abruptly pointed: 202 ­ 401 ­ 509 / 2 ­ 4 ­ 5 m; cladome 11 ­ 19 ­ 25 m wide, with short clads (Fig. 3 B): 5 ­ 11 ­ 16 m long. Anatriaenes with ill­formed and / or additional clads between the middle part of the rhabdome and the cladome are common. Oxeas fusiform, straigth or slightly curved, tappering gradually to sharp points (Fig. 3 C): 242 ­ 449 ­ 559 / 2 ­ 5 ­ 8 m. Microscleres absent.	en	Esteves, Eduardo L., Muricy, Guilherme (2005): A new species of Stelletta (Demospongiae, Astrophorida) without microscleres from Abrolhos Archipelago, northeastern Brazil.
