Pinheiro, U.</p> <p>Diagnosis. Megascleres tylostyles I range from 650 to 1200 µm; Tylostyles II range from to 220 to 740 µm. Microscleres selenasters and acanthomicrorhabds.</p> <p>Description. Encrusting sponge (Based on Holotype UFBA 4051 measurements: 72.31 150 mm length x 55.09 mm width and 4.05 mm thickness), covered by smooth and rigid cortical plates, separated by contractible grooves. Color in life light brown or dark brown (Fig. 2A), retained after alcohol preservation (Fig. 2B). Consistency is hard like a stone. Texture rugose, due to cortical plates. Oscules retracted after collection.</p> <p>Skeleton. Cortex composed of densely packed selenasters, with acanthomicrorhabds in ectosomal surface, over the selenaster crust. Choanosome with tylostyle bundles outwardly disposed, supporting the cortex, emerging from a basal layer of selenasters. Selenasters in different developmental stages and acanthomicrorhabds widely scattered in choanosome (Fig. 2C).</p> <p>Spicules. Megascleres. Tylostyles in two size categories. Tylostyles I (Fig. 2D), large, straight, with prominent tyles (Fig. 2E) and blunt points (Fig. 2F) (860–1033.5–1200 µm/7.5–11.9–15 µm). Tylostyles II (Fig. 2G), small, straight, with hastate ends (Fig. 2I) (220–402.9–740 µm / 5–6.9–10 µm).</p> <p>Microscleres. Selenasters in distinct growth stages, bean-shaped, oval or spherical (Fig. 2J) (35–59.5–71 µm / 22–45.1–52 µm) and young selenasters (Fig. 2K) (20–26.9–33 µm/8–13.2–20 µm). Curved/sinuous or straight acanthomicrorhabds (Fig. 2L), densely spined (6–9.1–11 µm/2–2.2–3 µm).</p> <p>Ecology. Encrusting sponges, found on the underside of rocks, at 0–20 m depths.</p> <p>Distribution. Southwest Atlantic, Brazil. Recorded from Northeast Brazil, Bahia State, Baía de Todos os Santos (Vera Cruz, Recife de Caramuanas, Aratuba beach) and south coast (Baía de Camamu, Maraú, Paciência da Terra). Pernambuco State, south coast (Cabo de Santo Agostinho, Praia Enseada dos Corais).</p> <p>Etymology. The specific epithet is dedicated to Dr. Gisele Lôbo Hajdu, for her important contribution in teaching/guiding dozens of biology students from South America and Europe since the 90’s, in phylogeography, ecology, taxonomy and molecular biology of sponges.</p> <p>Remarks. Placospongia giseleae sp. nov. is similar to the Pacific species P. santodomingoae, because of the similar spicule categories, showing tylostyles I with blunt ends and tylostyles II with hastate ends like and microscleres selenasters and acanthomicrorhabds are present. Nevertheless, the new species is unique by tylostyles I having twice the size (860–1033.5–1200/7.5–11.9–15µm) in comparison to the Pacific species (430–605.5–660/13– 15.5–20 µm). In addition, in P. giseleae sp. nov., tylostyles II are considerably longer (220–402.9–740 / 5–6.9–10 µm), when compared to tylostyles II of P. santodomingoae (240–290/5–8 µm).</p> <p>Microrhabds are considerably smaller in Brazilian species (6–9.1–11/2–2.2–3 µm), than in P. santodomingoae (8–12.3–18/2.5–2.7–3.5 µm) (Table 1). Selenasters measurements are also different, in the new species 35–59.5– 71/22–45.1–52 µm, being approximately the minimum size of the Pacific species (80–84.8–90/60–67.3–75µm).</p> <p>Besides the morphological differences between these two species P. giseleae sp. nov. is found at coral reefs from tropical regions, while P. santodomingoae is exclusively found in anchialine pools from Indonesia. Therefore, the considerable distance between the Southwestern Atlantic and the Indo-Pacific Ocean, gives further evidence of specific distinctness, considering the limited dispersal ability of this genus (Nichols &amp; Barnes (2005).</p> <p>The differences between the species recorded to the Caribbean Sea and the new species are mainly related to additional microscleres: (1) P. caribica presents spherasters, spirasters and oxyasters; (2) P. melobesioides shows spherules; (3) P. intermedia has spherasters and spirasters; (4). Furthermore, P. ruetzleri and the Brazilian species P. cristata has as additional microscleres, spirasters and spherasters, respectively. P. giseleae sp. nov. differs from all previous species by having only selenasters and acanthomicrorhabds as microscleres in spicule composition.</p> </div>	http://treatment.plazi.org/id/038CF27AF44D9B4CFF74FC0BF415F9B3	Public Domain	No known copyright restrictions apply.

Encrusting sponges (Based on UFBA 769 measurements: Fragment 1: 36.51 mm length x 14.83 mm width, 5.10 mm thickness, fragment 2: 28.56 mm length x 22.88 mm width, 4.10 mm thickness; fragment 3: 25.99 mm length x 19.71 mm width, 3.53 mm thickness), covered by smooth and rigid cortical plates separated by contractible grooves (Fig. 3A). Brown color in life. Firm consistency, non-compressible sponges. Oscules not observed.</p> <p>Skeleton. Cortex with densely packed selenasters. Choanosome with bundles of tylostyles disposed outwards, arising from a basal or a central axis of selenasters, providing support to cortex. Selenasters in different developmental stages, acanthomicrorhabds, and spirasters dispersed in the choanosome (Fig. 3B).</p> <p>Spicules. Megascleres. Tylostyles in two size categories, straight with spherical tyles, hastate and blunt (Fig. 3E) or mucronate (Fig. 3H) ends in both. Tylostyles I (Fig. 3C), larger (530–912.3–1150µm/12.5–16.5–20µm); tylostyles II (Fig. 3F), smaller (190–300.5–540µm/7.5–11.4–15µm). Microscleres. Bean-shaped to oval or sometimes spherical selenasters (Fig. 3I) (47–67.3–77µm/33–55.5–70µm). Irregular spirasters (Fig. 3J,K), with twisted shaft presenting one or two spiral turns, rays bifurcate or with tuft concentrated in the ends (8–13 rays), with shorter and longer secondary rays and spines. Microspined rays disposed sparsely, exclusively at the convex side (Fig. 3J) or densely in throughout the spicule (Fig. 3K), with two terminal clusters and rays in central region (13–19–23µm/3– 3.7–6µm). Acanthomicrorhabds abundant (Fig. 3L), with straight or slightly sinuous shafts (6–9.7–13µm/2–2.9– 4µm).</p> <p>Substratum, depth range and ecology. Encrusting rocky substratum in the intertidal zone, or subtidal to &lt;10 m deep.</p> <p>Distribution. Southwest Atlantic. Originally described from Suriname and the Guyana Shelf (Van Soest, 2017). In the present study, it is recorded for the first time from Brazil: Pernambuco State (Cabo de Santo Agostinho, Praia Enseada dos Corais), Bahia State (Camaçari: Northern coast, Todos os Santos Bay: Salvador, Praia Farol da Barra: central region and Baía de Camamu: Ilha da Pedra Furada).</p> <p>Remarks. P. ruetzleri was originally described from the Guyana shelf, in French Guyana and was reported from Florida, Jamaica, Grenada, Colombia and NE Brazil (van Soest, 2017). However, this Brazilian record was considered doubtful due to insufficient information (van Soest, 2017). In the present study, we confirm its occurrence to northeastern Brazil.</p> <p>In Suriname, this species was found in sandy bottom and in murky waters with muddy bottom at 25–34 m depths, the occurrence of sponges in this type of substrate is considered rare (van Soest 2017). Brazilian species of P. ruetzleri are recorded for intertidal reef environments, composed by sandy sediments at 0–10 m depths.</p> <p>Although the specimens from Brazil and from Suriname come from environments with distinct features (high turbid waters, and muddy bottoms in Suriname), the samples of these two regions contain the same spicular categories, with presence of unique spirasters with spines disposed exclusively at the convex side of the microsclere. In the Brazilian specimens, here described, the spirasters can be sparsely spined or, more rarely, densely spined.</p></div> 	http://treatment.plazi.org/id/038CF27AF44B9B4EFF74F965F471FB36	Public Domain	No known copyright restrictions apply.
