Sponge beige in ethanol with a foliaceous form (13 cm x 5.5 cm) and a large apical osculum (12 cm x 2 cm) (Figure 2 A). The surface is smooth but rough to the touch, and inhalant canals are conspicuous. The atrial cavity is very large, smooth, and centrally located. It has conspicuous exhalant canals and the aquiferous system is leuconoid.</p><p>The skeleton, composed of triactines and tetractines, is disorganized, which is typical for the genus. The cortical skeleton is composed of large tetractines tangentially disposed together with small triactines that form a reticulation (Figure 2 B). Large triactines and small tetractines I can also be found in the cortex, but are much less common. No subcortical lacunae are present. The choanosome is composed of small triactines and small tetractines I (Figure 2 C), the latter found mainly surrounding the inhalant canals where they project the apical actines inwards (Figure 2 D). Small tetractines II are found in the exhalant canals (Figures 2 E, 2F). The atrial skeleton is principally composed of large and small triactines (Figure 2 E). Large tetractines are rarely found in the atrial skeleton.</p><p>Spicules. (Table 2). Large tetractines (Figure 2 G): regular or subregular (i.e. spicules whose actines have different lengths and/ or different angles). The basal actines are conical with blunt tips (basal: 184–310–486 µm / 15–57–95 µm).</p><p>Large triactines (Figure 2 H): regular or subregular.

There are two species of Leucetta that, as also seen in L. foliata sp. nov., have more than one category of triactine and tetractine: L. floridana (Haeckel, 1872), known from the Caribbean and the Northeast of Brazil, and L. potiguar Lanna et al., 2009, endemic to the Northeast coast of Brazil (Lanna et al. 2009). Leucetta foliata sp. nov. contains three different types of tetractines, while L. floridana and L. potiguar have only two. In addition, L. foliata sp. nov. has large triactines and tetractines (although rare) in its atrial skeleton, which are not observed in L. floridana or L. potiguar . Finally, L. foliata sp. nov. has a distinctive external foliose morphology, not previously seen in the genus.</p></div>	https://treatment.plazi.org/id/C06287E2FFD5FFA5819C825516F0D003	Public Domain	No known copyright restrictions apply.

WAM Z45626=UFRJPOR 7125, from the same locality as the holotype, but station TPEH; WAM Z40348=UFRJPOR 7742, from the same locality as the paratype, but station JWAM 31 /Q3.</p><p>Description. Sponge beige in ethanol, massive (5.7 cm x 5.7 cm), with a conspicuous osculum apically (1 cm in diameter) (Figure 5 A). The surface is irregular and rough to the touch. The atrial cavity is large and conspicuously hispid (Figure 5 B). The aquiferous system is leuconoid.</p><p>The skeleton is disorganized. The cortical skeleton is composed of huge tripods and triactines with the tripods mainly concentrated near the osculum (Figures 5 A, 5C). Subcortical lacunae are present. The choanosomal skeleton is composed of triactines and tetractines I. The tetractines I mainly surround the inhalant canals with their apical actines pointing inwards (Figures 5 D, 5E). Exhalant canals are hispid and surrounded by tetractines II (Figure 5 F). The atrial skeleton is principally composed of tetractines II forming a conspicuous palisade of apical actines (i.e. a perpendicular arrangement of the apical actines) in the atrial cavity (Figure 5 F, 5B).</p><p>Spicules. (Table 6). Tripods (Figure 5 G): regular or subregular (actines with different lengths). Actines are stout and conical with blunt (sometimes rounded) tips (400–798–1050 µm / 150–237–350 µm).</p><p>Length (µm) Width (µm)</p><p>Spicule Actine Min Mean sd Max Min Mean sd Max n Tripods</p><p>WAM Z45632 (H) 450.0 611.0 88.1 700.0 220.0 257.0 21.1 290.0 10 WAM Z40489 (P) 500.0 798.0 151.2 1050.0 150.0 236.8 37.5 350.0 20 Triactines</p><p>WAM Z45632 (H) 87.5 118.3 12.3 137.5 12.5 16.8 1.8 20.0 20 WAM Z40489 (P) 97.2 124.9 16.8 165.2 12.2 14.9 2.1 19.4 20 Tetractines I Basal</p><p>WAM Z45632 (H) 92.5 116.9 17.8 150.0 11.2 14.4 1.7 17.5 20 WAM Z40489 (P) 94.8 122.1 15.5 170.1 9.7 14.1 2.1 21.9 20</p><p>Apical</p><p>WAM Z45632 (H) 37.5 60.6 13.4 100.0 5.0 5.8 1.0 7.5 20 WAM Z40489 (P) 15.0 34.3 18.5 87.5 2.5 5.5 1.2 7.5 20 Tetractines II Basal</p><p>WAM Z45632 (H) 100.0 144.7 18.3 175.0 17.5 20.9 3.2 27.5 20 WAM Z40489 (P) 120.0 164.7 19.4 200.0 15.0 17.0 1.8 20.0 20</p><p>Apical</p><p>WAM Z45632 (H) 285.0 422.7 73.7 545.0 25.0 39.2 8.4 55.0 20 WAM Z40489 (P) 280.0 475.5 91.0 725.0 17.5 22.6 2.0 25.0 20 Triactines (Figure 5 H): regular. Actines are conical with sharp tips (88–144–170 µm / 12–18–22 µm). Tetractines I (Figure 5 I, left): regular. The basal actines are conical with sharp tips. The apical actines are slightly conical and curved with sharp tips (basal: 97–125–163 µm / 10–14–22 µm; apical: 15–61–100 µm / 3–6–8 µm).</p><p>Tetractines II (Figure 5 I, right): regular or subregular. The basal actines are conical and undulating with blunt tips. The apical actines are conical, thicker and longer than the apical actines of tetractine I, with sharp tips and a conspicuous constriction at the base (basal: 100–165–200 µm / 15–21–28 µm; apical: 280–476–725 µm / 18–39– 55 µm).</p><p>Remarks. No species of Pericharax had previously been reported with tripods although there are two species of Leucetta with this kind of spicule: L. insignis Row &amp; Hôzawa, 1931 and L. prolifera (Carter, 1878) . However, the tripods of these two species are much shorter and thinner than those of P. vallii sp. nov. ( L. insignis: 200-260/ 30-60 µm; L. prolifera: 263-578/32-63 µm; P. vallii: 611-798/237-257 µm). In addition L. prolifera has tetrapods not seen in P. vallii sp. nov. The new species is also distinguished from all other Pericharax and Leucetta species by the presence of a palisade of apical actines in the atrial skeleton.</p></div>	https://treatment.plazi.org/id/C06287E2FFDFFFAC819C878814A2D76B	Public Domain	No known copyright restrictions apply.
