03EF87BEFFCEFFBB419BFF2AFA1974B7.taxon	description	Description. Thickly encrusting (Fig. 2 A), up to 0.7 cm thick. The holotype covered an area of approximately 10 x 5 cm (in life). Surface slightly rugose, with a few grooves. Oscules spread, few, smaller than 0.5 cm in diameter. Numerous other small openings occur all over the surface of the sponge (Fig. 2 B). Colour in vivo orange, turning to dark beige in ethanol. Consistency moderately compressible. Texture velvety. Skeletal architecture. Plumoreticulate (Figs 3 A – B). Acanthostyles form echinated tracts from the substrate to near the surface (Figs 3 C – D). Acanthostyles I (larger) core the tracts, while acanthostyles II (smaller) echinate those tracts. Tornotes are spread at random or slightly obliquely at the surface. These spicules, as well as acanthostyles and every microsclere category can be seen scattered in the choanosome too. Nevertheless, isochelae occur in larger quantities closer to the surface. Subectosomal lacunae were not seen, but numerous roundish canals (up to 700 µm in largest diameter) occur in the choanosome. Both the holotype and paratypes have their choanosome traversed by polychaete tubes. Spongin will envelop some of these choanosomal cavities and support erect acanthostyles I and II (Fig. 3 G). Larvae were observed in both specimens, up to 220 µm in diameter. Spicules. Megascleres (Tabs 1 – 2): Tornotes (Figs 3 H – I), straight, smooth, slightly aniso-tylote, 108 – 123.5 (8.4) – 135 / 2.5 – 3.5 (0.8) – 4.8. Acanthostyles I (Figs 3 J – K), straight or slightly curved; base roundish, narrow or slightly swollen; sharp apex, thinning gradually; spines in large numbers, up to 5 µm high, straight or slightly curved, distributed over the entire shaft and base, 180 – 202.5 (16) – 232 / 8 – 13 (2.6) – 16. Acanthostyles II (Figs 3 L – M), morphology similar to that of category I, but with smaller spines, 77 – 84.2 (4.4) – 95 / 4.8 – 7 (0.9) – 8. Microscleres (Tabs 1 – 2): Arcuate isochelae I (Figs 3 E, F, N), shaft arched, smooth and relatively stout; Alae slightly elongate and bent backwards; Young forms with markedly reduced alae, 31 – 39 (4) – 47. Arcuate isochelae II (Figs 3 E, F, O), morphology similar to that of category I, but smaller, 23 – 25.3 (1.2) – 29. Arcuate isochelae III (Fig. 3 P), more slender and smaller than both preceding categories; alae slightly elongate, but not bent backwards, 12.5 – 15.3 (1.8) – 18. Sigmas (Fig. 3 Q), contorted, smooth and pointy, 19 – 23.3 (1.5) – 26. Observation. Acanthostyles I (main choanosomal), acanthostyles II (echinating choanosomal), acanthostyles III (echinating choanosomal). Ecology. Grows over barnacles, bivalves and rock covered by coralline algae, in a community dominated by mytilids and Crepidula gastropods. A few bryozoans and corallimorpharians occurred over its surface.	en	Fernandez, Julio C.

03EF87BEFFCEFFBB419BFF2AFA1974B7.taxon	etymology	Etymology. The specific epithet ‘ ballena’ is used as a noun in apposition and refers to the species’ type locality. The word means whale in Spanish.	en	Fernandez, Julio C.

03EF87BEFFCEFFBB419BFF2AFA1974B7.taxon	discussion	Remarks. The Sturges algorithm (Sturges, 1926) confirmed the occurrence of two size classes of isochelae; i. e. 34 – 46.8 and 12.5 – 29.5. The smaller size class can be easily distinguished in two morphological categories, thus indisputably raising the number of categories in this proposed new species to three. As introduced above for the genus Lissodendoryx, the subgenus Ectyodoryx currently comprises 32 species recognized as valid according to van Soest et al. (2015), ten of which occur either in Chilean waters, or in neighboring biogeographic provinces, and demand a closer comparison. None of these, nevertheless, has three categories of isochelae as observed in L. (Ectyodoryx) ballena sp. nov. (Tab. 2). Furthermore, only four of these ten species possess ectosomal tornotes; viz. L. (E.) antartica, L. (E.) collinsi, L. (E.) jasonensis and L. (E.) minuta. However, these are quite larger than the tornotes of the new species. Even though van Soest et al. (2015) assign Lissodendoryx diversichela Lundbeck, 1905 in the N Atlantic to subgenus Ectyodoryx, we propose its transfer to subgenus Lissodendoryx on the basis of its original description with a single category of acanthostyles. To the best of our knowledge there has never been a subsequent taxonomic account of this species where a second category of acanthostyles had been found. We would like to highlight the fact that L. (L.) diversichela has three categories of isochelae, as found in the new species described above.	en	Fernandez, Julio C.

03EF87BEFFCAFFB7419BFF2AFEB7723D.taxon	description	Description. Massive oval shaped sponge (Figs 4 A – B; Figs 5 A – D), with numerous sinuous, short, anastomosing projections over the entire surface; resembling a cauliflower. The holotype is 4 cm long and 3 cm in high (in life) and the paratype is 3.8 cm and 3 cm, respectively. The paratype is relatively more compact. Simple oscula (diameter up to 0.3 cm, in vivo holotype), scattered and scarce. Colour in vivo beige, and in ethanol specimens are light beige. Their consistency is compressible, rather delicate, and the paratype is somewhat harder; texture slightly rough. Skeleton. The choanosomal skeleton is (sub) anisotropic (Fig. 6 A) or subisodictyal reticulation (Fig. 6 D). Larger acanthostyles form pauci- to multispicular ascending tracts (up to seven spicules across), reaching the sponge surface and piercing it by up to 300 µm. These acanthostyles also constitute secondary orthogonal tracts, one spicule long, and up to four in thickness (Figs 6 B, E). Smaller acanthostyles echinate the main choanosomal tracts, and the nodes of the reticulation. Tylotes are spread in the surface, often perpendicularly or obliquely (Fig. 6 C). Tracts are partially inserted in a spongin layer of fibrous appearance (Fig. 6 F). Two categories of arcuate isochelae are scattered all around in choanosome and ectosome, the smaller of which is more frequent. Subectosomal lacunae absent, but wide choanosomal cavities occur, roundish or variably ellipsoid, up to 2 mm in maximum diameter. Spicules. Megascleres (Tabs 2 – 3): (Sub) tylotes (Figs 7 A – B, I – J), straight, rather minutely microspined on both ends, which can be slightly aniso-tylote, elongated tyles only slightly swollen (elliptical), 108 – 172 (25.3) – 204 / 4.8 – 5.1 (0.3) – 6.

03EF87BEFFCAFFB7419BFF2AFEB7723D.taxon	discussion	Remarks. Lissodendoryx (Ectyodoryx) corrugata sp. nov. is distinguished from Lissodendoryx (E.) spp. occurring in the SE Pacific, and in additional allied biogeographic provinces, as well as from L. (E.) ballena sp. nov. (described above) by its possession of two categories of arcuate isochelae combined with terminally microspined tylotes. The presence of little spines in the extremities of tylotes is shared with five species of Lissodendoryx (Ectyodoryx) considered here (Tab. 2); viz. L. (E.) anacantha, L. (E.) nobilis, L. (E.) patagonica, L. (E.) plumosa, and L. (E.) ramilobosa. This character may also be present in the genus’ type species, L. (Lissodendoryx) isodictyalis (Carter, 1882). A phylogenetic assessment of synapomorphies is needed to verify whether the current subgeneric arrangement, and its emphasis on presence vs. absence of echinating acanthostyles (van Soest, 2002 a), is more parsimonious than an alternative system with greater weighting given to the micromorphology of spicules.	en	Fernandez, Julio C.

Globular (Figs 8 A – B), 4 cm in diameter x 3 cm high; hispid surface (Fig. 8 C); body made up of a dense mass of juxtaposed small slender hollow tubes (ca. 0.5 mm in diameter each ‘ fiber’), which may anastomose (Fig. 8 B); larger, simple openings (possibly oscula, up to 0.3 cm in diameter) are spread at the surface; colour in life beige, and in ethanol, lighter or darker beige; consistency rather compressible and delicate; rough texture. Skeleton. Sub-anisotropic reticulation (Fig. 9 A) of larger acanthostyles forming ascending pauci- to multispicular tracts (up to seven spicules across) in the choanosome, reaching the surface and piercing it by up to 200 µm. These acanthostyles also constitute secondary orthogonal tracts, one spicule long, and up to three in thickness (Fig. 9 B). Spongin in fibres is not apparent. These ascending spicule tracts can inter-cross or anastomose in the inner parts of the sponge, but are free from each other near the surface. Smaller acanthostyles echinate the main choanosomal tracts and the nodes of the reticulation. Tylotes are strewn at the surface, also tangentially (Fig. 9 C). Two kinds of arcuate isochelae occur throughout the choanosome and ectosome, the smaller category being the most abundant. Large choanosomal cavities are present, round or more elongated in section, up to 2000 µm long. Spicules. Megascleres (Tab. 2): Tylotes (Figs 9 D – E), straight, microspined at both ends, sometimes slightly aniso-tylote; tyles only slightly swollen and elongated, 150 – 187. 2 (14) – 198 / 4 – 4.7 (0.5) – 5. Acanthostyles I (Figs 9 F – G), straight to slightly curved, stout and somewhat fusiform; base slightly constricted, frequently bearing a subtle neck and discreet tyle, sometimes only irregularly round; apex sharpening gradually; spines (not abundant), up to 1.2 µm high, straight, concentrated on the basal portion of the spicule, a few spicules (variably thick) bear much less if any spines at all, 190 – 267.5 (34.3) – 300 / 7.2 – 8 (0.6) – 9. Acanthostyles II (Figs 9 H – I), frequently straight, base swollen (up to 3 µm thicker than the shaft); gradually sharpening apex; abundant spines up to 3 µm high, straight, spread all over the spicule, 84 – 100 (10) – 115 / 6 – 7. 5 (0.6) – 8.

Lissodendoryx (Ectyodoryx) coloanensis sp. nov. is distinguished from Lissodendoryx (E.) spp. occurring in the SE Pacific, additional allied biogeographic provinces, as well as L. (E.) ballena sp. nov., due to its two categories of arcuate isochelae combined with terminally microspined tylotes (Tab. 2). The spicule set of L. (E.) coloanensis sp. nov. is rather similar to that of L. (E.) corrugata sp. nov. (Fig. 9 and Fig. 7, respectively). Nevertheless, the former can be distinguished by its shorter and more slender acanthostyles (Tab. 2), besides a relatively distinct outer morphology and consistency (Fig. 8 e Figs 4 – 5, respectively).	en	Fernandez, Julio C.

03EF87BEFFC0FFB2419BFDD1FA2574CA.taxon	description	Description. The holotype is incomplete and therefore imprecise to describe its gross morphology. It is seemingly erect, possibly stalked (Fig. 10 A), ca. 2 cm high and 0.4 cm thick. Surface rather hispid, irregular, bearing short projections (Fig. 10 B) and roundish openings (ca. 0.1 cm across), which are of doubtful oscular in function. A gross reticulation is apparent in the entire sponge under transmitted light in a stereo microscope (Fig. 10 C). Colour in life not reported, dried holotype beige. Consistency relatively compressible and delicate, texture slightly rough. Skeleton. Plumoreticulate with a slight degree of axial compression (Figs 11 A – B). Larger acanthostyles core main paucispicular tracts (approx. five spicules across) that are entirely echinated by another two distinct types of acanthostyles (Fig. 11 C). Some of the larger acanthostyles fan out from the main tracts, interconnecting them. Aniso-subtylotes are scattered at the surface, disposed at various angles to it (Fig. 11 D). Isochelae and sigmas are scattered in the ectosome and choanosome. There is no spongin enveloping the fibres and subectosomal lacunae are absent. Choanosomal cavities (ca. 50 µm in diameter) are uncommon, scattered and roundish. Spicules. Megascleres (Tabs 2 – 4): Aniso-subtylotes to aniso-strongyles (Figs 12 A – B), straight, microspined ends, 223 – 233.5 (10.2) – 252 / 7.2 – 8.4 (1.3) – 9.6. Acanthostyles I (Figs 12 C – D), straight to slightly curved, stout and somewhat fusiform; roundish base, frequently narrower than the central portion of the shaft; gradually thinning point; surface with few straight spines (up to 2.5 µm), mainly over the basal third of the spicule, 435 – 536 (52.8) – 602 / 24 – 26.6 (2.4) – 31. Acanthostyles II (Figs 12 E – F), same overall morphology as the preceding category, but smaller, and bearing more spines, although the apical portion is also totally smooth, 320 – 391 (29.2) – 415 / 19 – 20 (1) – 21. Acanthostyles III (Fig. 12 H) straight to slightly curved; narrow roundish base; gradually thinning point; shaft completely covered with spines (moderately to abundantly), spines frequently straight and usually larger than those of the preceding categories, 220 – 232.5 (10) – 242 / 14 – 15 (1.1) – 17. Microscleres (Tabs 2 – 4): Arcuate isochelae (Fig. 12 I), shaft gently curved, lateral alae elongated and curved towards the shaft as a claw, frontal alae simple, 22 – 23.5 (1) – 24. Sigmas I (Fig. 12 J), contorted, smooth, with sharp ends, 45 – 55.5 (4.9) – 60. Sigmas II (Fig. 12 K) same morphology as the preceding one, but smaller, 16.8 – 20.8 (2.9) – 25. Ecology. Deep-water habitat (2000 m depth).	en	Fernandez, Julio C.

03EF87BEFFC0FFB2419BFDD1FA2574CA.taxon	discussion	Remarks. Lissodendoryx (Ectyodoryx) diegoramirezensis sp. nov. is distinguished from Lissodendoryx (E.) spp. occurring in the SE Pacific, additional allied biogeographic provinces, as well as L. (E.) ballena sp. nov., L. (E.) corrugata sp. nov., and L. (E.) coloanensis sp. nov., mainly by its possession of three categories of acanthostyles, separable by their dimensions, morphology and placement in the skeletal architecture (Tab. 2; Figs 12 C – H). Lissodendoryx (Ectyodoryx) diegoramirezensis sp. nov. has arcuate isochelae of uncommon morphology, with lateral alae of both extremities curved towards the shaft (Fig. 12 I). Precisely this isochelae morphotype can be found in L. (E.) anacantha (Hentschel, 1914: p. 107, Taf. VII, Fig. 12), a species amply distributed around Antarctic and the Subantarctic Region, and in another Antarctic species, L. (Lissodendoryx) styloderma Hentschel, 1914 (Hentschel, 1914: p. 101, Taf. VII, Fig. 7). This latter species can be readily distinguished from the new species by its lack of sigmas, possession of styles in the ectosome, and acanthostyles of a single category only. However, the similarity of the isochelae of the new species and those seen in L. (E.) anacantha might indicate a closer affinity between both species, as they further share similar habit and additional spicule characteristics. Nevertheless, both species are considered distinct on the basis of the presence of a third category of acanthostyles in the new species, while its acanthostyles, as a rule, are also more densely spined or with spines more widespread over the shaft. Furthermore, L. (E.) anacantha has ectosomal megascleres that can be perfect styles (Fig. 13 C – D), and the smaller category of acanthostyles may bear secondary microspines over the main spines seen at the base of the spicule (Fig. 13 E – F). These characteristics of the acanthostyles have not been spotted in the holotype of L. (E.) diegoramirezensis sp. nov. (Fig. 11 C – H). The re-examination of the type material of L. (E.) anacantha (Fig. 13) confirmed the spicule set originally reported by Hentschel (1914), and subsequently recognized by Koltun (1964). Nevertheless, new measurements obtained from the holotype (Tab. 2) revealed that acanthostyles can be much thicker than reported originally (Hentschel, 1914), matching more closely the measurements reported by Koltun (1964). Given the data at hand, L. (E.) diegoramirezensis sp. nov. is considered well distinguished from allied forms, but it is suggested that study of additional samples of L. (E.) anacantha, such as those registered (but not described) by Burton (1932) from South Georgia, is important to verify if these two taxa are distinct, as hypothesised here.	en	Fernandez, Julio C.
