654387C7FF9EFFDB6DB8FD3036330C13.taxon	description	Description. Sponge that lives in association with the calcareous algae Jania adherens J. V. Lamouroux, 1816, it is massive and has mounds that resemble small volcanoes. The oscula are circular and mostly oval, 2 – 6 mm in diameter (Figure 3 A). The surface is rough, not very compressible and brittle. The ectosome is regular, tangential, made up of single oxeas that are joined at each end by spongin (Figure 3 D). The choanosome is more difficult to differentiate due to the ramifications of the calcareous algae, but a reticulate network of spicule lines is distinguished (Figure 3 E). It has robust oxeas, with a slight curve in the middle and sharp ends (168.5 x 6.7 µm), the microsclere are C-shaped sigmas (20.4 µm) (Figure 3 B – C). Ecological notes. The species was found over rocks and calcareous algae from 12 to 16 m deep.	en	Trejo, Alejandra, Carballo, José Luis, Segovia, Johanna (2025): New records and checklist of sponges from El Salvador (Eastern Tropical Pacific).

654387C7FF9EFFDB6DB8FD3036330C13.taxon	discussion	Remarks. The specimens coincide with the original description in size and form of the spicules (Hetchel 1965). They also agree with the ones described by Cruz-Barraza & Carballo (2008) which they found between the intertidal to 6 m depth, unlike our specimens that were found from 12 to 15 m depth. There are two other Hacliclona (Soestella) species described from the eastern Pacific: H. (S.) spuma and H. (S.) roslynae Sim-Smith, Hickman & Kelly, 2021, but these species have larger oxeas (up to 192 x 13 µm and 117 x 7 µm respectively) and they lack of microsclere (Sim-Smith et al. 2021).	en	Trejo, Alejandra, Carballo, José Luis, Segovia, Johanna (2025): New records and checklist of sponges from El Salvador (Eastern Tropical Pacific).

654387C7FF9FFFD96DB8F92730E40803.taxon	description	Description. Erect sponge with cylindrical ramifications, and corrugated surface very difficult to break. The size of the sponge varies between 15 – 20 cm high by 16 – 20 cm wide. Branches have a diameter of 0.4 – 1.2 cm and in young sponges a simple bifurcation can be observed. It has small, slightly raised oscula. Color in life is orange and turns brown when preserved in alcohol (Figure 4 A). The skeleton is distinguished by having a condensed axial center that expands towards the surface (Figure 4 D), many styles exceed the surface of the sponge forming groups of spicules that resemble brushes (Figure 4 E). The spicules present are oxeas (260 – 501 µm) and styles (254 – 440 µm) (Figure 4 B – C). Ecological notes. The species was found on sandy substrate, usually in sites surrounded by large rocks and is colonized by large numbers of brittle stars.

654387C7FF9DFFD76DB8FC4237C30BCB.taxon	description	Description. Branched sponge 3 cm wide and 5 cm high. Each branch of the sponge has two rounded lobes, each 0.5 cm in diameter (Figure 5 A). The surface is irregular, no oscula are observed. Hard consistency and difficult to break. Color in life is bright orange with fine sediment on it, when preserved in alcohol it turns beige. The ectosome consists of a layer of straight, long and thin styles (200 – 250 x 1 – 2 µm) (Figure 5 B). There is an extra-axial subectosome made up of styles that project their tips toward the surface. The choanosome is a compressed axial skeleton formed by primary multispicular fibers interconnected by secondary fibers of two or more spicules, where styles and acanthostyles meet (Figure 5 C). The species presents styles in two categories, those of the ectosome that are straight and very thin, while those of the sub ectosome and choanosome are robust, with a sharp point and some are curved in the middle or in the third region closest to the head, the acanthostyles are stout with prominent spines from the mid-region to the tip of the spicule (Figure 5 D – F).

654387C7FF9DFFD76DB8FC4237C30BCB.taxon	discussion	Remarks. The specimen is similar to the original description in skeletal arrangement and spicule composition (De Laubenfels 1932), although, the size of our specimen is slightly larger, up to 5 cm high. Also, in the type specimen there are two size categories of choanosome styles, unlike our specimen where only one size category was found. Aguilar-Camacho et al. (2013) also describe specimens with a single size category of choanosome style, but these are much larger than the ones reported here (up to 780 µm length).	en	Trejo, Alejandra, Carballo, José Luis, Segovia, Johanna (2025): New records and checklist of sponges from El Salvador (Eastern Tropical Pacific).

654387C7FF93FFD56DB8FE41362A0D47.taxon	discussion	Remarks. Our specimens were found in only one coloration type, bright red to reddish-orange, with the typical formation of brushes composed of mycalostyles towards the surface of the sponge. We determined that the specimens correspond to M. cecilia due to the absence of ectosomal skeleton specialization, that is a shared characteristic within the genus Mycale (Carmia) Gray, 1867.

654387C7FF91FFD46DB8FF2936C3099B.taxon	description	Description. Massive sponge with 13 cm long x 16 wide coverage, it presents lobes 1 – 2 cm high and 1.3 – 1.9 cm in diameter. Color in life is orange-brown or purple-brown (Figure 7 A). Surface is irregular and smooth, but when observed under the microscope there are notable groups of spicules that protrude from it (Figure 7 B). The sponge is of compressible and elastic consistency. The skeleton is formed by a tangential reticulate ectosome containing fibers of multiple mycalostyles. The choanosome contains tracts formed by mycalostyles that arise from the base of the sponge and come to exceed the surface assimilating small brushes. Spicules are mycalostyles, isochelae, sigma and anisochelae in two size categories, toxa and raphides (Figure 7 C – I). Ecological notes. The species was found covering large rocks and calcareous algae up to 16 m depth.	en	Trejo, Alejandra, Carballo, José Luis, Segovia, Johanna (2025): New records and checklist of sponges from El Salvador (Eastern Tropical Pacific).

Color in life is bright yellow, it turns pale yellow when preserved in alcohol. It has oval oscular papillae of 2 – 4 mm in diameter slightly protruding from the surface (Figure 9 A). The skeleton consists of tylostyles and spiraster. Tylostyles have a wellformed head, are straight and with a pointed termination, measuring between 149 – 354.8 µm. Spiraster are short, stout and with many thick spines (Figure 9 B – C). The sponge was collected on calcareous algae at a depth of 6 m, and it was possible to observe it thanks to the oscular papillae that protruded from the surface. Ecological notes. The species was found over calcareous algae surrounded by turf and coarse sand.	en	Trejo, Alejandra, Carballo, José Luis, Segovia, Johanna (2025): New records and checklist of sponges from El Salvador (Eastern Tropical Pacific).

654387C7FF8AFFCE6DB8FE8130AE0E1E.taxon	discussion	Remarks. The specimen shares the common characteristics of the genus Suberea as the low proportion of fibers compared to the soft tissue. We state that the specimen belongs to S. etiennei because it has very thin fibers and the proportion of the pith is similar to the original description (Van Soest et al. 2011). There are only two species of Suberea described from the eastern Pacific: S. etiennei from Clipperton Islands, and S. esmerelda Sim-Smith, Hickman Jr & Kelly, 2021 from Galapagos Islands, this species differs with our specimen because of its morphological external characteristics as a massive and multilobate sponge with large conspicuous oscules at the ápex of the lobes, also its color in life is dull yellow to greenish grey (Sim-Smith et al. 2021).	en	Trejo, Alejandra, Carballo, José Luis, Segovia, Johanna (2025): New records and checklist of sponges from El Salvador (Eastern Tropical Pacific).

654387C7FF8BFFCC6DB8FA2F35C70BCB.taxon	discussion	Remarks. From the four species of the genus Aplysina reported in the Eastern Tropical Pacific, our specimen matches the description of A. chiriquiensis, since is the only species with pedunculate morphology and bright yellow coloration, although, the species can be found in color ranges from pinkish-red or purple too (Díaz & Van Soest 2005), the only coloration identified for our specimens was bright yellow. Our samples differ from the other species specially in morphology and coloration since A. clathrata Cruz-Barraza, Carballo, Rocha-Olivares, Ehrlich & Hog, 2012, is a semi-spherical to massive sponge with bright yellow or yellow to brown, red, violet or pink (Cruz-Barraza et al. 2012). The other two species A. gerardogreeni, Gómez & Bakus, 1992, and A. revillagigedi Cruz-Barraza, Carballo, Rocha-Olivares, Ehrlich & Hog, 2012, are cushion-shaped to massive sponges, the first one commonly yellow with tubes topped by an oscule and the second one usually green with oscula lineally on rims (Cruz-Barraza et al. 2012).	en	Trejo, Alejandra, Carballo, José Luis, Segovia, Johanna (2025): New records and checklist of sponges from El Salvador (Eastern Tropical Pacific).
