The consistency is soft, spongy, compressible and elastic. The surface is conulose. Coloration in life is unknown, fixed is light brown.</p><p>Skeleton. Plumoreticulated coanosomal skeleton, forming mycalostyle tracts that run towards the surface, with thinner tracts interconnecting the thicker tracts. Surface with strongly developed tangential skeleton, “Aegogropila type ”, with strongly intercrossed tracts, involving triangular meshes (Fig. 2B–D).</p><p>Spicules. Megascleres. Mycalostyles in two categories: straight, slightly curved to slightly sinuous, discrete tylus varying from elongated, lobed or styloid (Fig. 3C), with hastate or acerate tip (I: 230–294–350/3.7–8.1–12.5 μm) (Fig. 3A), (II: 190–225.8–290/1.2–2.1–2.5 μm) (Fig. 3B).</p><p>Microscleres. Palmate anisochelae in two size categories: I, with a palmate head that is approximately 54% of the total length of the spicule (Fig. 3I). This category forms rosettes on the ectosoma (45–50.2–58 μm; alae: 21.9– 26.9–32 μm) (Fig. 3D); II, with the head palmate approximately 62% of the total length of the spicule (15–19.8–25 μm; alae: 10–12.8–17.5 μm) (Fig. 3J). Palmate isochelae (10–11–12.5 μm) (Fig. 3H). The sigmas are C or S-shaped in two size classes: I, robust (80–91.5–100 μm) (Fig. 3F); II, smaller and thinner (12.5–17.6–27.5 μm) (Fig. 3G); Toxa with a central curvature, which can be accentuated or discreet (75–82.7–93 μm) (Fig. 3E). Microxea smooth and straight (20–28.6–38 μm) (Fig. 3L).</p><p>Distribution. Belize (Rützler et al., 2000), Martinica (Pérez et al., 2017), Panamá (Díaz, 2005), Colombia (Bowerbank, 1876), Suriname (Van Soest, 2017).

Mycale (Z.) angulosa shows great morphological variation (Muricy &amp; Hajdu, 2006; Muricy et al., 2008; Hajdu et al., 2011). This was also observed in the material analyzed, where we found specimens with encrusting (UFBA 2621), massive (UFBA 802 and UFBA 3977) and branched arborescent (UFBA 1128, UFBA 2458, UFBA 2362) growth forms. The specimens studied differ from the previous characterizations of M. (Z.) angulosa by the presence of microxea. However, this character has already been observed in M. (Z.) angulosa by Custódio et al. (2002): 24.8–38 μm and Lerner et al. (2005): 20–28.1–43 μm with the same size variation in the material studied 20–28.6–38 μm.</p></div>	https://treatment.plazi.org/id/03A087ACFFF0923FFF3EF9DB177B7CC1	Public Domain	No known copyright restrictions apply.

Northeast Brazil, Bahia State, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=-38.510555&amp;materialsCitation.latitude=-12.9366665" title="Search Plazi for locations around (long -38.510555/lat -12.9366665)">Todos-os-Santos Bay</a> (Boa Viagem Beach) (12°56’12’’S – 038°30’38’’W) .</p><p>Etymology. The specific name “ odoya ” refers to the greeting to the Orisha Yemanja, an African Deity. Odoyá is a Yoruba word that means “Mother of the waters”. Yemanja is worshipped worldwide as the mother of all Orishas, while in Salvador, Yemanja is worshipped mainly as a sea goddess.</p><p>Remarks. Mycale (Z.) odoya sp. nov. is similar to Mycale (Z.) ramulosa Carballo &amp; Cruz-Barraza, 2010 and Mycale (Z.) pectinicola Hentschel, 1911 due to the massive form with arborescent branches in M. (Z.) ramulosa and the purple colour in M. (Z.) pectinicola . However, the new species shows different sizes of mycalostyles compared to both species. Mycalostyles in Mycale (Z.) odoya sp. nov. range from 128 to 295 µm, while in M. (Z.) ramulosa, mycalostyles vary from 290 to 317 µm, and in M. (Z.) pectinicola they range from 200 to 318 µm. Additionally, considering the proximity in the size of the megascleres in M. (Z.) ramulosa and M. (Z.) pectinicola, it is possible to observe that there is no exclusivity in the measurements of megascleres for these species, with an overlap in the sizes of both species (Table 1).</p><p>Moreover, Mycale (Z.) odoya sp. nov. shows mycalostyles and styles megascleres and three palmate anisochelae (I, II and III), while M. (Z.) ramulosa and M. (Z.) pectinicola have only one category of megascleres, represented by mycalostyles, and two categories of palmate anisochelae, with absence of anisochelae III. According to the morphological structure, palmate anisochelae I in the new species are similar to palmate anisochelae I in M. (Z.) ramulosa and in M. (Z.) pectinicola sensu Calcinai et al. (2013), because both species have the same shape and size. However, palmate anisochelae III in the new species is morphologically similar to palmate anisochelae II in M. (Z.) ramulosa .</p><p>Micracanthoxas observed in Mycale (Z.) odoya sp. nov. as well as in M. (Z.) ramulosa and M. (Z.) pectinicola are only visible by scanning electron microscopy due to their usually small size (3 to 19.6 µm, Table 1).</p><p>Mycale (Z.) odoya sp. nov. differs from Mycale (Z.) angulosa mainly due to the presence of micracanthoxas and three categories of palmate anisochelae in the former, while M. (Z.) angulosa has only two categories of palmate anisochelae (I: 40–51 µm and II: 15–20 µm) and micracanthoxas are absent. Additionally, Mycale (Z.) odoya sp. nov. has a reticulate skeleton, while M. (Z.) angulosa has a well-defined plumose architecture.</p></div>	https://treatment.plazi.org/id/03A087ACFFF79233FF3EFE6811C97935	Public Domain	No known copyright restrictions apply.

The term “ policuspidifera ” refers to the cusp found at the pointy end (apex) of the subtylostyles due to its characteristic tridentate or polydentate nature.</p><p>Remarks. The Mycale (P.) subgenus has 18 valid species worldwide, with three species formerly registered in the Atlantic Ocean: Mycale (P.) spinosigma (Boury-Esnault, 1973), Mycale (P.) vitellina Van Soest, 2009 and Mycale (P.) atlantica Stephens, 1917 (De Voogd et al., 2024). This subgenus is characterized by the presence of serrated sigmas (Van Soest &amp; Hajdu, 2002).</p><p>Mycale (P.) policuspidifera sp. nov. is similar to Mycale (P.) vitellina (Curaçao) in its thinly encrusting form, yellow colour in situ and possession of the same spicule categories, but the new species presents smaller subtylostyles with tridentate or polydentate apices (165–266 µm), while in the Caribbean species megascleres are styles (276– 348 µm) without any notable details as “teeth” on their apices. In addition, microscleres sigmas (34–51 µm) and anisochelae I (20–31 µm) are smaller in the Brazilian species when compared to M. (P.) vitellina which has much larger sigmas (78–93 µm) and anisochelae I (65–70 µm) (Table 3).</p><p>The new species differs from M. (P.) atlantica due to the latter species possession of toxas, absent in the new species, and lack of ornamentation on its subtylostyles. Moreover, its subtylostyles and sigmas are larger than those observed in the new species.</p><p>......continued on the next page</p><p>......continued on the next page</p><p>Hajdu &amp; Rützler (1998) had the opportunity to examine a fragment from the holotype of M. (P.) spinosigma (MNHN D NBE 968) and were unable to find any anisochelae. Furthermore, the characteristic sigmas were very rare, which led these authors to suspect they might actually be contaminants. We consider thus that M. (P.) spinosigma is best treated as a species inquirenda and refrain from any comparison with our newly proposed species.</p><p>Mycale (P.) policuspidifera sp. nov. shares the presence of megascleres with bidentate, tridentate or polydentate apices with Mycale (P.) curvisigma (Lévi, 1969), M. (P.) serratohamata (Carter, 1880), M. (P.) moluccensis (Thiele, 1903) and M. (P.) sceptroides Van Soest, Aryasari &amp; De Voogd, 2021 . However, all species mentioned present megascleres that are substantially larger than those of Mycale (P.) policuspidifera sp. nov. (Table 3), which is considered a well distinguished new species.</p></div>	https://treatment.plazi.org/id/03A087ACFFFD922EFF3EFEDD17FC7BB5	Public Domain	No known copyright restrictions apply.

Mycale (Mycale) salvadorensis sp. nov. includes massive and encrusting specimens, with two categories of anisochelae (I and III), two categories of sigmas (I–II) and two of raphides/trichodragmas (I–II).</p><p>External morphology. The holotype is fragmented, a larger fragment measuring 8 x 4.5 cm (length x width). Massive, flattened sponge with some fistules (Fig. 10A) and encrusting form (Fig. 10B–C). Rough, smooth and irregular surfaces. Consistency compressible and easy to tear. The colour is brown in situ and in alcohol (Fig. 8B–C).</p><p>Skeleton. The surface skeleton is a tange ntial layer of single intercrossing megascleres (Fig. 10D). Rosettes with the largest anisochelae are common, measuring approximately 150µm in diameter (Fig. 10E). The surface membrane between the megascleres is charged with scattered sigmas and anisochelae, and abundant raphides form trichodragmas. The choanosomal skeleton at the base consists of strong, plumose bundles of megascleres that can reach 750 µm in diameter, fanning out in the subectosomal region (100–225 µm in width) carrying the surface skeleton.</p><p>Spicules (dimensions of holotype UFBAPOR 4593). Megascleres. Mycalostyles in two categories, fusiform, with faint constriction beneath the rounded heads and a sharply pointed end/tip: I, choanosomal (Fig. 11A) (354– 521.4–687/7.3–11–17) and II, ectosomal (Fig. 11B) (323–482.4–667/4.3–8.5–12.2 µm).</p><p>Microscleres. Anisochelae I (Fig. 11C), robust, with head approximately 25% of the total spicule length, shaft markedly curved (46–54–59 µm, head: 10–17–15 µm).Anisochelae III (Fig. 11D), smaller, with head approximately 60% of the total spicule length (14.6–18.1–19.5 µm, head: 6–10–12 µm). Sigmas, thin, with slightly incurved apices in two distinct size categories, (I) larger, C or S-shaped, very common, 26.8–37.1–56 µm (Fig. 9E), and (II) smaller, C- shaped less common, 9.7–13.1–17 µm (Fig. 11F). Raphides in two size categories are extremely common, (I) larger (Fig. 11G, R 1), 66–79.3–119 µm in length, and can be found in trichodragmata (Fig. 9H), (II) smaller (Fig. 11G, R 2), 17.4–24.2–44 µm in length.</p><p>Ecology. The holotype (UFBAPOR 4593) is associated with the sponge Coelosphaera sp. and the paratype (UFBAPOR 1866) with the sponge Hyattella cavernosa (Pallas, 1766) .</p><p>Distribution. Brazil: Bahia State (type locality—present study). Suriname (Van Soest, 2017).</p><p>Etymology. The species’ specific epithet is dedicated to the type locality, the city of Salvador.</p><p>Remarks. Mycale (M.) has 55 valid species in the world, five of which are recorded for the Brazilian coast: M. (M.) alagoana Cedro, Hajdu &amp; Correia, 2011; M. (M.) arenaria Hajdu &amp; Desqueyroux-Faúndez, 1994; M. (M.) beatrizae Hajdu &amp; Desqueyroux-Faúndez, 1994; M. (M.) laevis (Carter, 1882) and M. (M.) quadripartita Boury-Esnault, 1973 (De Voogd et al., 2024; Pinheiro et al., 2025). In the present study, Mycale (M.) salvadorensis sp. nov. is the sixth species of Mycale (M.) for the Brazilian coast.</p><p>The new species is closely related to M. (M.) arenaria, because both species have a similar spicule set, with two categories of mycalostyles (I and II) and two categories of anisochelae [(I), head about 25% the entire spicule height and foot alae prolonged basally forming a round pore (Fig. 11C); and (III), head comprising 60% of the entire spicule height, rudimentary foot bearing a basal spur (Fig. 11D)]. However, the new species has smaller anisochelae III (19.6–20.7–23.5 µm) when compared to those of M. (M.) arenaria (17.2–26.8–41 µm) (Table 4) and a third category of anisochelae (anisochelae-II), rare in M. (M.) arenaria, is absent in the new species.Additionally, Mycale (M.) salvadorensis sp. nov. presents trichodragmas in two size categories, with smaller sizes (I: 78–79.2–119 µm; II: 17.4–24.2–44 µm) when compared to the single category in M. (M.) arenaria (55–88.4–113 µm) (Table 4).</p><p>The specimen from Guyana identified as M. (M.) arenaria by Van Soest (2017) has external morphology and spicule dimensions very similar to those of M. (M.) salvadorensis sp. nov., which prompted us to consider it conspecific with the new species.</p><p>Mycale (M.) salvadorensis sp. nov. has massive or encrusting growth forms and differs from M. (M.) beatrizae and M. (M.) alagoana in that they are only encrusting, and from M. (M.) quadripartita, which is tubular. The new species presents anisochelae I of distinct morphology (curved axis instead of straight in side view) and larger trichodragmas (I: 66–79.3–119 µm; II: 17.4–24.2–44 µm) when compared to M. (M.) laevis (I: 44–66–80 µm; II: 19–21–24 µm) (Table 4). Mycale (M.) beatrizae has only one category of mycalostyles, no trichodragmas, and its smaller category of anisochelae (III) bears no basal spur-like projections. This is in marked contrast to the new species’ two categories of mycalostyles and trichodragmas, as well as smaller anisochelae (III) with a basal spur-like projection.</p><p>......continued on the next page</p><p>Mycale (M.) salvadorensis sp. nov. presents only anisochelae I and III, with the same morphology as those in M. (M.) alagoana, but the latter has anisochelae II additionally. Mycale (M.) quadripartita has three categories of anisochelae with heads approximately 40%, 50% and 50% of the total spicule height, respectively, all with rounded bases without spur-like projections. Accordingly, it differs from the new species by the number and shape of its anisochelae, as well as its much larger sigmas and trichodragmas in seemingly only a single category (Hajdu &amp; Desqueyroux-Faúndez, 1994).</p></div>	https://treatment.plazi.org/id/03A087ACFFE79220FF3EFF25149A7C2D	Public Domain	No known copyright restrictions apply.
