Diagnosis: Bright yellow live-colour and small (1-6 cm high) digits and/or fusiform processes topped by oscula. Description: Specimens can have few (3–4) or many digits (60–80), which are mostly erect. Digits can be single or anastomosed, cylindrical (fusiform or straight) or slightly volcaniform (rare), 1–6 cm high and 0.6–1.5 cm wide (Figs. 1 A, 2 A–B). Area coverage can be as large as 25 x 15 cm, but more often about 6 x 6 cm. Surface is finely conulose. Oscula are mostly apical (1.5–4 mm in diameters), but few lateral and smaller (ca. 1 mm in diameter) can occur. The colour is bright yellow in vivo, which turns into deep purple after preservation in alcohol. Consistency is soft and flexible Skeleton: Choanosome with a delicate and irregular network of spongin fibers. They have a bark with amber colour and thickness of 25–100 Μm (average 44 Μm), and black or amber pith with thickness varying between 11 and 81 Μm (average 16 Μm) (Figs. 2 C–E, Tab. I). TABLE I: Spongin fibres’ measurement data for Aplysina caissara Pinheiro & Hajdu, 2001 (in micrometers; S.D. = Standard Deviation and N = 30). Specimens Locality* Fibers Piths Distribution: Provisionally endemic from southern and southeastern Brazil (24–28 º S, Fig. 3 A). This area is known as the Paulista Biogeographic Province. Ecology: The species has a typically patchy distribution, being often very rare, but reaching considerable densities at a few spots, where specimens can be found every couple of meters. Its known depth distribution is from 0.5 to 12 m. Few specimens are found at very shallow depths (0.5–3 m) in places of somewhat restricted water flow, where temperatures may reach 28 º C. However, most are located in areas of large water circulation and intermittently exposed to the Central South Atlantic waters, with temperatures reaching a minimum around 13 º C (Pinheiro & Hajdu, 2001). Remarks: Among the Tropical South-western Atlantic Aplysina that possess digitiform processes, the species which most closely resembles A. caissara is A. fulva, known by its large morphologic variability along the Brazilian coast (cf. Pinheiro & Hajdu, 2001). However, A. caissara combines a bright yellow colour in life, the consistently small dimensions (digits 5 cm high), never possesses typically apical oscula, nor a comparably delicate reticulation of spongin fibres.Published as part of Pinheiro, Ulisses Dos S., Hajdu, Eduardo & Custódio, Márcio R., 2007, Aplysina Nardo (Porifera, Verongida, Aplysinidae) from the Brazilian coast with description of eight new species, pp. 1-51 in Zootaxa 1609 on pages 3-7, DOI: 10.5281/zenodo.17887

Neves coll., XI/ 1999. Diagnosis: Irregular polygonal tubes, laterally anastomosed, predominantly beige in vivo. Colour ranging from bright pale-yellow to dark reddish-brown. Description of the species: Specimens are composed of laterally anastomosed tubes with an irregular polygonal outline, in creeping groups of up to 45 tubes, with clusters having a maximum of 36 cm in length and 3 cm in width. The polygonal outline results from discrete edges extending upwards from the base of the sponge on its free sides (Figs. 17 C–F, 20 A–B). Some short tubes are projected from the base in varied directions. The surface is finely conulose. The sponge possesses large pseudoscula, frequently apical or pseudo-apical (eccentric), varying from 0.5 cm to 1 cm in diameter, small oscula on the tubes’ outer sides being also visible. In specimen MNRJ 2139, oscula have an iris-type diaphragm. The predominant colour in vivo is beige, specimens with green, brown, brownish-beige and red tinges being also common. After preservation in ethanol specimens vary from beige to brown. Consistency is soft. Skeleton: Choanosome with a delicate and irregular network of spongin fibers (Figs. 20 C–D) with amber colour bark 38–126 Μm thick (average 72 Μm) and a thick pith that can be black or amber 8 to 50 Μm (average 29 Μm; Fig. 20 E). The presence of spongin fibers wrapped and excavated by filamentous structures, possibly fungi, was observed in some specimens as in Aplysina pseudolacunosa sp.n.

Ecology: All specimens were collected in shallow-waters at Atol das Rocas, inside large crevices, and the species is thus considered to be sciaphilous. Inside the atoll, depth of occurrence was limited to 5 m, but outside the atoll ring, specimens were seen down to 15 m. Specimens in darker areas were completely beige, and those more exposed to light, more intensely pigmented with darker colours, as a likely consequence of association with cyanobacteria. Etymology: The name of the species honours Dr. Guilherme Muricy, for his pioneering studies on the taxonomy of Atol das Rocas sponges, who also collected many of the specimens studied here. Remarks: The species which appear closest to A. muricyana sp.n are A. insularis and A. pseudolacunosa sp.n. described below. Another similar species is A. fistularis, which presents tubes of distinct morphology, never forming the large, frequently creeping clusters so frequently observed in the new species. Tubes in A. fistularis, albeit varied as regards length, as well as number and size of projections, were never seen to have a polygonal cross section. The possibility that A. muricyana sp.n. could be nothing but an ecomorph of a well established species appears quite unlikely, as dives performed on the outer ring of Atol das Rocas, down to 15m depth, failed to reveal any additional Aplysina species. Rather, the same A. muricyana sp.n. was present inside somewhat deeper crevices (10–15 m depth). Another species which also presents anastomosed tubes is A. insularis. However, A. insularis has soft and stout tubes, with yellow or brown colour in vivo turning black after preservation. In contrast, A. muricyana sp.n. has hard, much less stouter polygonal tubes, with variable colour in vivo and brown or beige colour after preservation. Comparison with A. pseudolacunosa sp.n. will be provided below.Published as part of Pinheiro, Ulisses Dos S., Hajdu, Eduardo & Custódio, Márcio R., 2007, Aplysina Nardo (Porifera, Verongida, Aplysinidae) from the Brazilian coast with description of eight new species, pp. 1-51 in Zootaxa 1609 on pages 36-39, DOI: 10.5281/zenodo.17887

Hypleurochilus brasil differs from its congeners by the following combination of characters: pelvic-fin rays I, 3, dorsal fin predominantly XII, 13, anal fin II, 15 or 16 (usually 16), absence of blackened stripes, nape green or white and presence of numerous tiny red spots along body, diminishing in size posteriorly (Figures 3 and 4). Description. Dorsal-fin rays XII, 13 or 14, 13 in 5 specimens and 14 in 4 specimens; anal-fin rays II, 15 or 16, 15 in 3 specimens and 16 in 6 specimens; branched caudal-fin rays 8, total segmented caudal-fin 12; pectoral-fin rays 14; pelvic-fin rays I, 3; precaudal vertebrae 11, caudal vertebrae 25. Gill opening ending at or slightly above dorsal end of the pectoral fin base. Lateral line straight and short, with 24 distinct tubes, never extending beyond the first segmented dorsal ray. One to four cirri present on anterior nasal opening and one or two on top of eyes. Body moderately elongate, without scales. Head length 3.18 (2.98–4.14) in SL, orbit diameter 4.09 (2.84–4.64) in head length, pectoral-fin length 3.74 (2.73–3.9) in SL and pelvic-fin length 6.11 (4.61–7.69) in SL (Table 2). Horizontal mouth situated low on the head; maxilla reaching posteriorly to a vertical through the centre of eye. Incisiform teeth 25 in the upper jaw and 24 or 25 in the lower jaw. Two large curved canine teeth posteriorly on each side of dentary, at end of incisiform series, and in upper and lower jaws. Cephalic sensory pores arranged in two rows inferior and posterior of eye, one row above superior lip, two rows below lower lip; two arrow-shaped rows on nape, one right posterior to eyes and one slightly anterior to dorsal fin. Colour in life. Individuals shortly after death (approx 2 h) and alive are shown in Figures 3 and 4 to illustrate the colour pattern of the new species. The body is translucent with pale brown tint in juveniles and strongly orange in adults, both with many red spots along sides of body. Adults with transverse pale and dark bars on head and posterior part of body. Nape variable in coloration, green or whitish in juveniles, black in adults. Black pupil surrounded by red iris with black stripes giving the appearance of spokes in a wheel. Snout pale yellow with whitish or bluish streaks. Operculum and pre-operculum bordered with series of white dots. Pectoral, pelvic and anal fins, and basal part of caudal fin yellow, without dots or spots. Dorsal and caudal fins hyaline. Colour in alcohol. Body pale brown, red spots in live specimens turn brown (Figure 2). Top of head dark brown. Snout with brownish streaks. Fins pale. Series of white dots on the operculum and pre-operculum disappear. Etymology. The name of the new species refers to the vivid red spots that are like incandescent pieces of a brazing. Brazil’s country name (Brasil in Portuguese), where the species is endemic, originally has a similar derivation. The name of the country was given in recognition of the reddish colour of the wood of a large Brazilian native tree (Caesalpinia echinata – “Pau-Brasil” in Portuguese), very abundant in the past. The name is treated as a noun in apposition. Distribution and habitat. Hypleurochilus brasil sp. n. is known only from the type locality (Figure 5), and is considered to be endemic to Trindade Island and the Martin Vaz Archipelago. This species was recorded from 3 to 15 m depth, it was found either solitary or in small groups (up to 10 individuals), always in small holes or associated with sea-urchins and sponges on the rocky reefs (Figure 4). Remarks: Hypleurochilus brasil is distinguished from H. langi, H. bananensis, H. springeri, H. bermudensis, H. aequipinnis and H. pseudoaequipinnis by having pelvic-fin rays I, 3 (versus I, 4). It differs from H. caudovittatus, H. fissicornis, H. germinatus and H. multifilis by dorsal fin predominantly XII, 13, anal fin II, 15 or 16 (usually 16), absence of black stripes and presence of numerous tiny red spots along body (Figures 3 and 4), diminishing in size posteriorly. Its peculiar coloration (vivid orange spots, nape green or white) is different from all congeners except H. springeri and some H. aequipinnis. A recent phylogenetic analysis shows a low level of divergence between Hypleurochilus brasil sp. n. and H. fissicornis (0.6–0.8 %; Levy et al. 2013). These two species differ in number of dorsal and anal-fin rays (Table 1). Hypleurochilus brasil was misidentified as H. fissicornis by Gasparini & Floeter (2001) and is considered as Hypleurochilus n. sp. by Levy et al. (2013).Published as part of Pinheiro, Hudson T., Gasparini, João Luiz & Rangel, Carlos A., 2013, A new species of the genus Hypleurochilus (Teleostei: Blenniidae) from Trindade Island and Martin Vaz Archipelago, Brazil, pp. 95-100 in Zootaxa 3709 (1) on pages 96-100, DOI: 10.11646/zootaxa.3709.1.5, http://zenodo.org/record/21847

Both genera are similar and share tylotes, styles, acanthostyles and toxas in their spicule set. However, <i>Acheliderma</i> differs by the absence of cladotylotes. Additionally, <i>Acarnus microxeatus</i> <b>sp. nov.</b> presents fusiform microxea instead of the elongated diamond-shaped ones seen in <i>Acheliderma</i>. The presence of acanthose microscleres is observed in several genera of Acarnidae. <i>Acheliderma</i>, <i>Dolichacantha</i> Hentschel, 1914, <i>Megaciella</i> Hallmann, 1920 and <i>Paracornulum</i> Hallmann, 1920 all have acanthostyles. <i>Wigginsia</i> de Laubenfels, 1953 and <i>Zyzzya</i> Laubenfels, 1936 have acanthostrongyles, and <i>Acanthorhabdus</i> Burton, 1929 has acanthorhabds. Only <i>Cornulella</i> Dendy, 1922 shares acanthoxea with <i>Acarnus microxeatus</i> <b>sp. nov.</b>, but differs from <i>Acarnus</i> by the absence of cladotylotes, and the fistular habit (Aguilar-Camacho <i>et al.</i> 2013, Van Soest <i>et al.</i> 1994, Hooper 2002).</p> <p> <i>...Continued on the next page</i></p> <p>References.

We emphasize that <i>Acarnus microxeatus</i> <b>sp. nov.</b> differs from all congeners by having microxeas and acanthoxeas as microscleres (Figs 3I and 3G, respectively). <i>Acarnus primigenius</i>, <i>A. radovani</i>, <i>A. souriei</i> and <i>A. tener</i> present only one category of cladotylotes with spined shaft and base with recurved spines, differing from <i>A. microxeatus</i> <b>sp. nov.</b> which has two categories of cladotylotes, the largest one, with a smooth shaft and rounded lobed base (Fig. 3D). Additionally, all these species, mentioned above, have styles with a microspined and/or rough head, in contrast to the totally smooth head of styles in <i>A. microxeatus</i> <b>sp. nov.</b> (Table 2). The new species presents three categories of toxas, differing from <i>A. caledoniensis</i>, <i>A. guentheri</i>, <i>A. levii</i>, <i>A. michoacanensis</i>, <i>A. peruanus</i> and <i>A. tener</i> that have two categories, and <i>A. primigenius</i>, that has only one category. Furthermore, <i>A. caledoniensis</i> has two categories of acanthostyles and is spherical in shape, while <i>Acarnus microxeatus</i> <b>sp. nov.</b> has one category of acanthostyles and is thickly encrusting. <i>Acarnus bicladotylotus</i> and <i>A. nicoleae</i> differ from <i>A. microxeatus</i> <b>sp. nov.</b> by having larger tylotes (143–404 μm and 119–380 μm, respectively against 190– <i>211</i> –249 μm) and also for having smaller accolada toxas (150–250 μm and 140–330 μm, respectively against 222– <i>435.6</i> –656 μm) (Tables 1 and 2). Additionally, none of these species of <i>Acarnus</i> have acanthoxea and smooth microxea as the new species do (Table 1, 2, 3 and 4).</p>Published as part of <i>Nascimento, Elielton & Pinheiro, Ulisses, 2023, A new species of Acarnus Gray, 1867 (Porifera, Demospongiae, Acarnidae) from NE Brazil, pp. 521-540 in Zootaxa 5293 (3)</i> on pages 523-529, DOI: 10.11646/zootaxa.5293.3.5, <a href="http://zenodo.org/record/7961435">http://zenodo.org/record/7961435</a>
