8D3BBA430C08F144FF127067A1983512.taxon	description	Description. Sponge with dimensions (5 x 3 mm (length x width) — largest specimen), massive, which can vary from lamellar, conulose with a hispid surface (mainly at the ends of the conules). Soft consistency, can easily break apart. External coloration, in situ, varies from orange to greenish. When preserved, dark brown externally, and varies internally from light brown (specimens UFBA 3169 and 2724 - POR) to very dark brown towards the surface (seen only in UFBA 2724 - POR) (Fig. 2 A). Oscules and pores not visible. Skeleton. Consisting of a basal grouping of polyactines. Ectosome specializations absent with dense spongin fibers. Basal fibers centered by plumose, multispicular, bundles of styles. With long and thin extra-axial styles, bases of which are attached to the choanosome fibers with the ends protruding through the surface. Extra-axial spicules also scattered across the choanosome. Fibers very well-packed with polyactines (Fig. 2 B), producing an almost rigid, closed and darkened secondary skeleton. Spicules. Three kinds of styles and two kinds of polyactines (Fig. 2; Table 1).

8D3BBA430C08F144FF127067A1983512.taxon	discussion	Remarks. The specimen (UFBA 2724 - POR) was epibiotic with Mycale (Aegogropila) americana Van Soest, 1984. Sponge color permitted partial identification, but the association was confirmed by the dissociated spicule slides and thick sections of skeleton architecture. The samples UFBA 1430 - POR and UFBA 752 - POR, despite not having been included in the morphometric comparative table, are both conspecific with C. agnani after morphological study of samples and slides of skeleton architecture and spicules. Studied C. agnani specimens (Table 1) are similar to C. vickersii originally described by Bowerbank (1864) for the West Indies as Dictyocylindrus vickersii, in terms of encrusting to massive sponges with a rough surface. Contrary to most other authors referring to C. vickersii, Van Soest et al. (2012) showed that this species is endemic to the Indian Ocean and does not occur in the Western Atlantic. They demonstrated evidence including the uncertainty of the origin of the type specimen and the different descriptions of the species over time for the West Indies and Atlantic Ocean. The sample assembly here studied fits with C. agnani in terms of external and internal characters. A remarkable variation in the young and smooth form of polyactine was pointed out by Van Soest et al. (2012) between the holotype of C. agnani described for Brazil (Espirito Santo state) and the specimen from Colombia (Santa Marta region). We here consider a second category of polyactine for this young, smooth form with a larger clade (also found in Cyamon pedroalcoladoi sp. nov.). Regarding comparative material (MNRJ and MHNBA) the specimens described here have few variations in measurements of the spicules (Table 1) and colour. It is worth highlighting, however, an additional variation regarding the form of polyactines I in the samples of C. agnani examined by Van Soest et al. (2012) and those considered in the present study: although all contain spines along the clades, in the specimens from Brazil (holotype and additional materials) the cladi are robust, but with endings that are always discreetly tapered, culminating in sharp or slightly rounded points; while the specimen from Colombia has well-developed apical tyles. For now, the specimens from Colombia and Brazil are considered conspecific with C. agnani, since to elucidate the status of all these samples a broad review including also the molecular approach of type and additional samples is recommended.	en	Ozga, Aline Vasum, Menegola, Carla (2023): Hidden treasures of Camamu Bay, Bahia, Brazil: New records and two new species of Raspailiidae (Porifera, Demospongiae).

8D3BBA430C0CF14BFF1276A1A05432A4.taxon	discussion	Remarks. Cyamon pedroalcoladoi sp. nov. is closely related to C. agnani (Fig. 5; Table 2) described for northeastern Brazil and reported from the Caribbean (Colombia) by Van Soest et al. (2012). The new species differs from C. agnani by having two kinds of strongyles, and two additional kinds of styles. The details of megascleres here highlighted have not been documented in the general literature and in the review of Cyamon by Van Soest et al. (2012). Cyamon pedroalcoladoi sp. nov. possesses style V sinuous, not observed in C. agnani from Brazil. Regarding C. agnani, Van Soest et al. (2012) pointed out the notable variation between the holotype described by Boury-Esnault (1973) for Brazil (Espirito Santo state), deposited at the Natural History Museum in Paris, and the specimen from Colombia (Santa Marta region), deposited at the Amsterdam Zoological Museum, which had a young and smooth form of polyactines (also found in Cyamon pedroalcoladoi sp. nov. and named here as polyactines II. In relation to the other Cyamon species from the Atlantic (Fig. 5; Table 2), C. arguinense has, in addition to the styles, a subtylostyles type, absent in the new species, and its polyactines has tapered tips in all cladi, while polyactine I of Cyamon pedroalcoladoi sp. nov. has a tapered clade and others that are rounded. While C. amphipolyactinum has an amphipolyactine kind that is absent in Cyamon pedroalcoladoi sp. nov. but which has two kinds of usual shape of polyactines (cladi diverging from a single central point). The new species differs from all other species in the genus by having strongyles and two additional kinds of styles. The strongyles I are long and thin, leaving the spicule delicate and easy to break during dissociation and slide preparation. To measure 30 complete spicules of strongyles I, it is necessary to prepare a larger number of slides. The description of Cyamon pedroalcoladoi sp. nov. increases to four the number of known species of the genus in the Atlantic Ocean, of which two are known from shallow waters off Brazil. This first record of C. agnani in Bahia expands the geographic and depth limits for this species.	en	Ozga, Aline Vasum, Menegola, Carla (2023): Hidden treasures of Camamu Bay, Bahia, Brazil: New records and two new species of Raspailiidae (Porifera, Demospongiae).

One kind of strongyles, three kinds of styles and one kind of raphides (Fig. 7 A – N; Table 3). Strongyles (Fig. 7 A – D) — Long or short, thin or thick, straight or slightly curved at the center, with the ends varying from rounded to telescopic: 175 – 460.8 – 1125 / 72.5 – 9.1 – 15 µm. Styles I (Fig. 7 E – G) — Long and thick with pointed and / or rounded ends: 875 – 1177.5 – 1400 / 7.5 – 11.3 – 17.5 µm. Styles II (Fig. 7 H – J) — Long and thin, smooth and straight, with one end rounded and the other sharp: 250 – 776 – 1350 / 2.5 – 4.3 – 10 µm. Styles III (Fig. 7 K and L) — Short and thick, spined with an accumulation of juxtaposed spines directed towards the center of the spicule and with a crown of spines at the end. Pointed tips, rarely rounded: 92.5 – 153.4 – 177.5 / 5 – 7.8 – 10 µm. Raphides (Fig. 7 M and N) — Short and thin, straight with rounded ends: 250 – 344.3 – 450 / 1 – 1.6 – 3 µm	en	Ozga, Aline Vasum, Menegola, Carla (2023): Hidden treasures of Camamu Bay, Bahia, Brazil: New records and two new species of Raspailiidae (Porifera, Demospongiae).

This species is dedicated to Mel, the cute and unforgettable basset hound who was our inseparable friend during the manuscript writing, with her loud and happy barks, her unconditional love, and who passed away shortly before the submission of this paper.	en	Ozga, Aline Vasum, Menegola, Carla (2023): Hidden treasures of Camamu Bay, Bahia, Brazil: New records and two new species of Raspailiidae (Porifera, Demospongiae).

8D3BBA430C01F14CFF127556A0A6302E.taxon	discussion	Remarks. Thrinacophora melae sp. nov. differs from the other species of the genus by having strongyles, not documented in the literature so far, therefore requiring the redefinition of the genus Thrinacophora for its inclusion. Other similarities are the presence of styles I and raphides in both species. However, both species differ mainly in the occurrence of strongyles and styles (three categories) in Thrinacophora melae sp. nov. and of oxeas and styles (two categories) in T. funiformis. Comparing the species Thrinacophora melae sp. nov. with T. murrayi Arnesen, 1920 and T. spinosa Wilson, 1902, which also occur in the Western Atlantic, the presence of strongyles and styles III exclusive to the new species is a notable difference. Thrinacophora melae sp. nov. and T. dubia Brøndsted, 1924, which occurs in the Western Pacific (Auckland and Campbell Islands, New Zealand) are the only two species to share spined styles III, but differ by the presence of strongyles and styles II in the former. Studies on the genus are scarce, such as Hooper (1991) who carried out a review of the family Raspailiidae but, with regard to Thrinacophora, considered only the species T. cerviconis Ridley & Dendy, 1886. Hooper (2002) defines Thrinacophorinae, redescribing in his study only T. funiformis, which is also registered by Rützler et al. (2009) and Van Soest (2017) for the Northern Gulf of Mexico) and Guyana / Suriname, respectively. Thrinacophora melae sp. nov. increased the number of species described for the Atlantic Ocean to four, with T. funiformis and Thrinacophora melae sp. nov. now registered for Brazil, highlighting here an additional specimen of T. funiformis (MUCIN 0143) from the type locality (Salvador, Bahia).	en	Ozga, Aline Vasum, Menegola, Carla (2023): Hidden treasures of Camamu Bay, Bahia, Brazil: New records and two new species of Raspailiidae (Porifera, Demospongiae).
