Alejandra Trejo, det. José Luis Carballo. External morphology. Endolithic sponge in alpha morphology. No observations available on distribution and sizes of papillae. Live color orange. Excavation. Samples too small to assess bioerosion traces. Spicules. Megascleres slightly curved tylostyles, microscleres kidney- or C-shaped microstrongyles (Fig. 11). Tylostyle dimensions: 12 2–284 µm (x̅=176.2, σ=39.4) x 2.2–9.7 µm (x̅=5.4, σ=2.4). Microstrongyle dimensions: 14.9–29.7 µm (x̅=20.7, σ=4.7) x 2.6–16.6 µm (x̅=7.4, σ=4.2). Ecology. Found in dead shells and coral skeleton of Pocillopora sp., between 3 and 8 m depth. Distribution and previous records. The species was originally described (Carballo & Cruz-Barraza 2005) and was again observed from the Gulf of California (Carballo et al. 2008b; Vega 2012). It is presently reported for the Pacific of El Salvador and Costa Rica (Fig. 12). This new record extends the distribution of this species. Remarks. Due to the characteristic kidney-shaped microstrongyles C. microstrongylata is easy to identify. It has only recently been described in detail (Carballo & Cruz-Barraza 2005), and we provided only a short taxonomic account to illustrate the present identification.Published as part of Pacheco, Cristian, Carballo, José Luis, Cortés, Jorge, Segovia, Johanna & Trejo, Alejandra, 2018, Excavating sponges from the Pacific of Central America, descriptions and a faunistic record, pp. 451-491 in Zootaxa 4370 (5) on page 462, DOI: 10.11646/zootaxa.4370.5.1, http://zenodo.org/record/114721

UES.CI.72: Playa el Faro, Los Cóbanos, El Salvador, <3 m, 24.X.2016, coll. Alejandra Trejo, det. José Luis Carballo. External morphology. Endolithic sponge in alpha morphology. Material not sufficient to allow full description of external characters. Live color yellow. Excavation. No data available. Spicules. Megascleres as oxeas, spined or smooth, centrotylote or simple (Fig. 32). According to length, two types of oxeas. Smaller oxea dimensions: 27.5–101.5 (x=¯54.7, σ=18.1) x 1.5–9 µm (x=¯4.8, σ=2.1); larger oxea dimensions: 110–297 µm (x̅=196.2, σ=69.1) x 3.5–13 µm (x̅=8.2, σ=3.2). Microscleres as oxyaster derivates and amphiasters (Fig. 31, 32). Smooth oxyasters with actines extending from nodular centre, form variable depending on number of actines, ranging between two and four (V-shaped biactine, triactine or tetractine). Dimensions of oxyaster actines: 17.5–51 µm (x̅=31.1, σ=9.4) x 1–4 µm (x̅=1.9, σ=0.8). Amphiasters with five or six actines with microspination on each axis, actine tips coniform or as branch terminating in groups of spines or hooks. Depending on actine lengths, amphiasters symmetric or asymmetric. Amphiaster length from tip to tip 7.9–17.3 µm (x̅=12.9, σ=3.5), axis width 1.0–2.2 µm (x̅=1.6, σ=0.4), actine length 1–5 µm (x̅=3.6, σ=1.5). Ecology. Found at 5 m depth. Distribution and previous records. T. calpulli was described by Carballo et al. (2004) from Nayarit, Mexican Pacific. In this study it was found in El Salvador and Costa Rica (Fig. 33). This represents new records for the two countries, as well as for Central America. Remarks. The characteristic ornamentation of amphiasters with conical spines, and the spicular complex with tylostyles, oxyasters and centrotylotes oxeas distinguished this species from other Thoosa (Carballo et al. 2004).Published as part of Pacheco, Cristian, Carballo, José Luis, Cortés, Jorge, Segovia, Johanna & Trejo, Alejandra, 2018, Excavating sponges from the Pacific of Central America, descriptions and a faunistic record, pp. 451-491 in Zootaxa 4370 (5) on pages 478-480, DOI: 10.11646/zootaxa.4370.5.1, http://zenodo.org/record/114721

Alejandra Trejo, det. José Luis Carballo. External morphology. Endolithic sponge in alpha morphology. Small circular papillae on average 600 µm in diameter. Live color not recorded. Excavation. Multicamerate erosion. Chambers with average diameter of 860 µm (Fig. 16A). Erosion scars 15–66 µm in diameter, with occasional circular ridges and sharp edges (Fig. 16B). Spicules. Megascleres as small tylostyles and derivates, mostly with subterminal tyles, occasionally far displaced or duplicated, forming tylostyles, tylostrongyles, subtylostyles, and sometimes centrotylote derivates (Fig. 17). Tylostyle dimensions: 72–253 µm (x̅=146.7, σ=48.0) x 2–16 µm (x̅=6.8, σ=3.3). Ecology. Found in Pavona sp. at 14 m depth. Distribution and previous records. The species was described from the Mexican Pacific (Bautista-Guerrero et al. 2006) and again reported from the same area (Carballo et al. 2008a). The present specimen was collected at Isla del Coco, off Costa Rica and in El Salvador (Fig. 18). Our findings represent a new record for Central America, in particular for El Salvador and Costa Rica. Remarks. As this species was only recently described in good detail (Bautista-Guerrero et al. 2006), we only provided a short taxonomic account. The tylostyles of C. pocillopora are comparatively short for a clionaid sponge and characteristic in shape, making this identification easy to perform.Published as part of Pacheco, Cristian, Carballo, José Luis, Cortés, Jorge, Segovia, Johanna & Trejo, Alejandra, 2018, Excavating sponges from the Pacific of Central America, descriptions and a faunistic record, pp. 451-491 in Zootaxa 4370 (5) on page 467, DOI: 10.11646/zootaxa.4370.5.1, http://zenodo.org/record/114721

MZUCR.380: Isla del Caño, 10 m, 12. II.2011, coll. and det. Cristian Pacheco Solano. External morphology. Endolithic sponge in alpha morphology. Material not sufficient to allow reliable description of external characters. Excavation. Fused galleries with average diameter of 2 mm. Erosion scars with diameters between 29 and 56 µm. Inner surface of scars irregular, with pronounced ridges and radial structures (Fig. 34), providing additional information to distinguish between Thoosa and Cliona (Calcinai et al. 2004). Spicules. Megascleres tylostyles and oxeas, microscleres oxyaster derivates and amphiasters (Fig. 35). Tylostyles scarce, not measured. Oxeas centrotylote, with length average of 57.4 µm (σ=7.7). Thick amphiasters with 14 nodules, 2 at each apex and 6 per verticil, in alternating arrangement. Nodules microspined. Nodulose amphiaster average dimensions of 21,3 µm (σ=2.3) x 14,1 µm (σ=2.4). Thinner amphiasters with fourteen nodules in arrangement as described above, irregular endings or smooth, with average dimensions of 17,1 (σ=3.0) x 10,2 µm (σ=2.4). Biradiate, triradiate or tetraradiate oxyasters, some with microspination, length average of 50,5 µm (σ=7.2). Ecology. The specimens were found in dead pocilloporid corals at 10 m depth. Distribution and previous records. The species was described from Mexico (Carballo et al. 2004), and Guzmán (1988) probably from Costa Rica (see Remarks), which our study confirmed (Fig. 36). Todate Costa Rica was the only site in Central America where this species was detected. Remarks. The three Thoosa species presently known in the ETP— T. calpulli, T. mismalolli and Thoose purpurea Cruz-Barraza et al., 2011 —are quite easy to distinguish by comparing the most common spicule, the main amphiaster (Fig. 31, 35 and Fig. 9A in Cruz-Barraza et al. 2011). However, all three species were only recently described and any findings before 2004 relied on the then existing literature. Guzmán (1988) sampled a Thoosa species from Costa Rica and identified it as Thoosa mollis Volz 1939. However, the distribution of this species is restricted to the Adriatic Sea in the Eastern Mediterranean (Soest et al. 2016). In this study, we found two species of this genus, T. mismalolli and T. calpulli in Costa Rica. Guzmán’s material was very likely T. mismalolli, as the spicules of T. mollis and T. mismalolli are similar.Published as part of Pacheco, Cristian, Carballo, José Luis, Cortés, Jorge, Segovia, Johanna & Trejo, Alejandra, 2018, Excavating sponges from the Pacific of Central America, descriptions and a faunistic record, pp. 451-491 in Zootaxa 4370 (5) on pages 481-482, DOI: 10.11646/zootaxa.4370.5.1, http://zenodo.org/record/114721
