0380878FFFACFFC947956A81F16CFEFF.taxon	diagnosis	Diagnosis. Halichondria (Halichondria) marianae sp. nov. differs from other Tropical Western Atlantic species by its combination of long and robust oxeas (large than 500 µm) and dark green color. External morphology (Fig. 2 A – D). Thickly encrusting to massive sponges. The preserved holotype consist of one fragment, one 9.5 x 2.5 x 3 cm (length x width x thickness). Surface rugose and rough. Regularly oscular projections or diffusely distributed along the top of the sponge (Fig. 2 A – D) less than 4 mm in diameter, generally in rows, some with membranous rims slightly down. Some specimens with subectosomal thin canals ending in oscula. Texture firm, soft, fleshy, but compact and compressible. Color in vivo is dark green (externally) and greenish (internally), becoming grayish or brownish after fixation (ethanol 92 %).	en	Santos, George Garcia, Nascimento, Elielton, Pinheiro, Ulisses (2018): Halichondriidae Gray, 1867 from the Northeastern Brazil with description of a new species.

0380878FFFACFFC947956A81F16CFEFF.taxon	description	Skeleton (Fig. 2 E – F). Ectosome detachable from choanosome. The ectosomal skeleton is typically composed of a regular reticulation of tangentially arranged tracts (40 – 90 µm in diameter) of oxeas (Fig. 2 E). Choanosomal skeleton is typically halichondrid (Fig. 2 F), with oxeas of variable length organized in a confused fashion, showing a tendency to form ascending tracts (30 – 160 µm in diameter). Tracts form small brushes of oxeas perpendicular in the surface (see Fig. 2 F). Many loose interstitial spicules in the basal and deeper regions. Pigmented cells in both regions and little spongin present. Spicules (Fig. 3 A – B, Table 1 and 2). Oxeas smooth, varying from straight to slightly curved, not divisible into two categories (90 – 340.4 – 800 / 5 – 11 – 20 µm).	en	Santos, George Garcia, Nascimento, Elielton, Pinheiro, Ulisses (2018): Halichondriidae Gray, 1867 from the Northeastern Brazil with description of a new species.

0380878FFFACFFC947956A81F16CFEFF.taxon	discussion	Remarks. Halichondria (Halichondria) marianae sp. nov. differs from the other 13 species recorded for the Tropical Western Atlantic by its combination of long and robust oxeas and dark green color. The most similar species is Halichondria (H.) melanadocia de Laubenfels, 1936 from Florida due to the detachable ectosome, choanosomal with spicules strewn in confusion and fusiform oxeas. However, both species clearly differ in the size of the oxeas, whereas in new species is larger than Halichondria (H.) melanadocia (Table 2). Additionally Halichondria (H.) melanadocia have a black color whereas the new species is green (see Table 2). Another Tropical Western Atlantic Halichondria species is Halichondria (Halichondria) corrugata Diaz, van Soest & Pomponi, 1993, but it has smaller and thinner spicules than new species (Table 2). Additionally, Halichondria (H.) corrugata also present color light greenish-brown or pink and lobate growth form against dark green color and thickly encrusting to massive form in the new species.	en	Santos, George Garcia, Nascimento, Elielton, Pinheiro, Ulisses (2018): Halichondriidae Gray, 1867 from the Northeastern Brazil with description of a new species.
