7974B36EFFAB0948B1FAB14BC1D0EC65.taxon	etymology	Etymology. The species name is from the Latin glacies, ice, and philum, nature, since it only seems to appear in fjords influenced by icebergs (and their sediment). Habitat, distribution and abundance. The species was found between 10 and 15 m depth on vertical rocky walls of the Tempano fjord (Central Patagonian Zone) which is under strong influence of glacial sediment. It is one of the few species that withstands strong stress from fine glacial sediment.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFAB0948B1FAB14BC1D0EC65.taxon	discussion	Remarks. Alcyonium sollasi Wright & Studer, 1889, from the Straits of Magellan and Shag Rocks, has similar rods in the interior (see Verseveldt & Ofwegen, 1992). It differs in colony shape, with many rounded lobes, and in having clubs with less spiny heads in the surface of the coenenchyme. Moreover, preserved colonies have a brown or yellowish white color, while all specimens of A. glaciophilum n. sp. are orange. A. haddoni Wright & Studer, 1989, from the Messier Channel, Chile, and A. patagonicum (May, 1899), from the Patagonian Shelf, can have a similar colony shape as A. glaciophilum n. sp. Both species, however, lack the sparsely ornamented rods in the interior of the colony.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFAC0948B1FAB663C623E948.taxon	description	Description of RMNH Coel. 34936. The colony is membranous, about 1.5 cm long and 1 cm wide (Fig. 1 c). Polyps are evenly distributed over the colony. Calyces are dome shaped and all polyps are partly retracted with tentacles withdrawn. Anthocodiae have a collaret of a few irregularly arranged rows of spindles; the points have many spindles. In order to preserve as much as possible of the fragment no microscope slides were made for drawing the anthocodial sclerite arrangement. The collaret spindles are up to 0.55 mm long, with spines and prominent simple tubercles (Fig. 5 a – b). Points have spindles similar to those of the collaret, with clubs present distally, up to 0.30 mm long (Fig. 5 c). The tentacles are without sclerites. The surface layer of calyces and membrane has exclusively capstans, 0.10 – 0.15 mm long (Fig. 5 d, h). The interior has tuberculated spindles (Fig. 5 f – g, i), the longest present in the calyces, up to 0.40 mm long. Some of these spindles are club-like (Fig. 5 e), but real clubs were not observed. Colour. The preserved colony is white, and all sclerites are colourless. Habitat, distribution and abundance. The species occurs in South Georgia, and was collected only once in Chile, at 1800 m depth.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFAC0948B1FAB663C623E948.taxon	discussion	Remarks. ZSM 20061187 is also only a fragment, but a large part of that colony has been photographed, showing more of its colony shape (Fig. 1 b). The species was originally described from off Shag Rocks and South Georgia, at 152 – 335 m depth (Casas et al., 1997: 308). All six colonies of the type series showed colonies with numerous lobes, the largest colony, the holotype, even reaching 16.5 cm in height. It is remarkable that the present material forms encrusting sheets. However, comparison of sclerites showed the present material in close agreement with A. grandis, and therefore we identified it as this species despite the big difference in colony shape. The species differs from all the other species in Chile by the total lack of clubs in the coenenchyme.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFA20945B1FAB483C6E5E88D.taxon	description	Description of RMNH Coel. 34937. Colony consisting of a single, flattened, rounded lobe, 3.5 cm high, 3 cm wide, and 1.5 cm thick (Fig. 1 e). Polyps distributed over the whole surface of the colony, almost reaching the base. Calyces are dome shaped and all polyps are retracted. Anthocodiae have a collaret composed of 5 – 6 rows of spindles (Fig. 3 c); these spindles are up to 0.40 mm long, with simple tubercles (Fig. 6 a). Points have spindles similar to those of the collaret, with clubs present distally, up to 0.25 mm long (Fig. 6 b). In the tentacles spiny rods are found, up to 0.20 mm long (Fig. 6 c). The surface layer of the top of the colony has clubs, up to 0.20 mm long, with spiny heads (Fig. 6 d); the interior has spindles with rather complex tubercles, up to 0.30 mm long (Fig. 6 e). The surface layer and interior of the base of the colony have sclerites similar to those of the top of the colony (Fig. 6 f – g), but they are slightly shorter. Colour. The orange colour of the live colony is still preserved; tentacle rods are colourless, other sclerites yellow. Habitat, distribution and abundance. This species is the most abundant of all Alcyonium species so far recorded in Chile. Specimens inhabit rocky and biogenic substrata (dead gorgonians, chitons) starting in 6 m depth in channels of the North and Central Patagonian Zone from 43 ° 09 ' 02.1 " S, 73 ° 35 ' 30.9 " W to 51 ° 36 ' 20.8 " S, 73 ° 55 ' 33.8 " W. The typical colonies are round to slightly elongated with a distinct domeshaped extremity and consist of a single lobe. On rare occasion, however, colonies are longer and / or slightly to strongly lobed with each lobe having a dome-shaped extremity (see variability). In several colonies, conspicuous pink eggs / larvae were visible through the transparent body wall of some polyps. On one colony (Fig. 3 c) the amphipod Metepimeria acanthurus was observed. Variability. RMNH Coel. 34938 is similar to RMNH Coel. 34937, but larger, with cream to orange color, and with many polyps expanded (Fig. 1 f). Therefore, this specimen was used to make the drawing of the polyp armature (Fig. 3 c). In this specimen the polyps are up to 1.20 mm wide and 1 mm high. All recently collected material examined except two seem to consist of a single lobe. One of the colonies of ZSM 20061191 has some irregular outgrowths, probably re-growth after damage instead of real lobes. RMNH Coel. 34940 seems to be a digitate colony (Fig. 2 c), but could be the result of several digitiform colonies grown together to form one large digitate colony. It surely is an exceptional growth form for this species and therefore SEM images of its sclerites (Fig. 7 a – d) and a lateral view of its polyp armature (Fig. 3 b) are presented. Specimen RMNH Coel. 34940 has somewhat larger anthocodial sclerites, up to 0.50 mm long, and the distal ones are less club-like. Furthermore its internal spindles are less tuberculate. We consider these differences intraspecific variation and despite its aberrant growth form to belong to A. haddoni. The ZSM 20061190 colonies have a white base and polyps, with all anthocodial and base sclerites colourless.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFA20945B1FAB483C6E5E88D.taxon	discussion	Remarks. Alcyonium haddoni was described by Wright & Studer (1889), found 315 m deep in the Messier Channel, Chile. In their publication the description of the colony shape was rather misleading (see remarks of A. roseum). Therefore, here two syntypes of A. haddoni (BMNH 89.5.27.125) are shown in Fig. 1 d. Also the sclerites of this species were depicted rather schematic (pl. 42 fig. 6). Verseveldt (1967) re-examined the syntype material of A. haddoni in order to identify material collected east from Rio de la Plata, Argentine. He noted some significant sclerite differences between his material and the syntypes but nevertheless decided the Rio de la Plata material belonged to A. haddoni. Two microscope slides of the top of the colony of a syntype, made by Verseveldt, are stored in the RMNH, and were re-examined by us. They showed much wider clubs in the top of the colony (up to 0.10 mm wide heads) than those in the recently collected material. Only after examining the MZUC-UCCC 8156 material did it become obvious that this difference probably represents intraspecific variation as MZUC-UCCC 8156 shows clubs (Fig. 7 e) intermediate between the syntype and the recently collected material. We have our doubts about the identification of Verseveldt (1967), the colonies he depicted are digitate and the clubs are even less developed than in our material. It is very unlikely Pérez & Zamponi (2004) had A. haddoni as their colony was clearly lobate.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFA10943B1FAB351C1D2E93D.taxon	discussion	Remarks. Because RMNH Coel. 34944 has a rather long stalk, compared with the other specimens, SEM images of its sclerites are presented as well (Fig. 8 i – k). It shows capstans and clubs similar to those of the other material, but the sclerites of the interior of the base (Fig. 8 j – k) are more irregularly shaped. As only one specimen was available with these characters we tentatively included it in this species. Alcyonium jorgei n. sp. resembles A. yepayek n. sp.; both species have digitate colonies, and both have similar rods in the interior of the colony. A. jorgei differs in having more slender lobes, and clubs with more spiny heads, and mostly without central wart.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

In the tentacles spiny rods are found, up to 0.20 mm long (Fig. 9 d). The surface layer of the lobes has clubs, up to about 0.25 mm long, with spiny heads (Fig. 9 e). The interior of the lobes has tuberculated spindles, up to 0.30 mm long (Fig. 9 f). The surface layer of the membrane has capstans and clubs (Fig. 9 g). The capstans are up to about 0.10 mm long, most of the clubs are slightly longer, some reaching 0.25 mm in length. The interior of the membrane contains tuberculated spindles (Fig. 9 h), up to 0.30 mm long; similarly shaped to those of the lobes. Colour. Alive the colony was pink (Fig. 2 f), preserved it is white, and all sclerites are colourless.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFA40940B1FAB483C134E9B2.taxon	etymology	Etymology. The species name is the Latin roseum, rose, referring to the colony colour. Habitat, distribution and abundance. The species was regularly found on biogenic substrata (e. g. dead gorgonians, polychaete tubes) which were found on moderately steep or vertical rocky substratum below 15 m depth in the channels of the Central Patagonian Zone (see Pickard, 1973) between 48 ° 17 ' 30 '' S, 74 ° 20 ' 10 '' W and 51 ° 36 ' 20.8 " S, 73 ° 55 ' 33.8 " W in the Chilean fjord region. At these sites currents were moderate to strong and sedimentation relatively low. The colonies can cover entire dead gorgonians or just a part of them.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFA40940B1FAB483C134E9B2.taxon	discussion	Remarks. Alcyonium antarcticum Wright & Studer, 1889, from Antarctic and Sub Antarctic waters, and A. haddoni Wright & Studer, 1889, from the Messier Channel, Chile, have been described as having membranous colony forms. A. antarcticum indeed can be membranous (see Verseveldt & Ofwegen, 1992), but Wright & Studer described their A. haddoni as “ In this species the colony forms very variously shaped and sized masses, which grow over the dead stems of a Muriceid ”, suggesting it has a membranous colony form. However, none of the three specimens mentioned in their publication was depicted. Here we show two of these syntype specimens of A. haddoni, BMNH 89.5.27.125 (Fig. 1 d), which clearly demonstrate it is not an encrusting species. A. antarcticum differs from the present species in having less tuberculate capstans in the surface and lacking the characteristic clubs at the tentacle bases reported for the present material. Above we described encrusting specimens of A. grandis Casas et al. That species differs from Alcyonium roseum n. sp. in totally lacking clubs.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFBB095CB1FAB483C7BFEC15.taxon	description	Description. The holotype consists of three lobes encircling a gorgonian branch (Fig. 1 i). The largest lobe is one cm long and wide, the other two are smaller, a real stalk is lacking. Because all polyps were retracted in the material studied the arrangement of anthocodial sclerites was not examined. The collaret spindles are up to 0.35 mm long, with simple tubercles (Fig. 10 a). Points have spindles similar to those of the collaret, with clubs present distally, up to 0.15 mm long (Fig. 10 b). In the tentacles spiny rods are found, up to 0.15 mm long (Fig. 10 c). The surface layer of the lobes has small clubs, mostly up to 0.15 mm long, a few up to 0.25 mm long, with leafy heads, and many of them with a central wart (Fig. 10 d); the interior has spindles with simple tubercles, up to 0.40 mm long (Fig. 10 e). The surface layer of the base of the colony has tiny capstans (Fig. 10 f), up to 0.10 mm long; the interior has spindles and rods, up to 0.25 mm long (Fig. 10 g – h). Colour. Alive (Fig. 2 h) and preserved the colonies are orange. Most anthocodial and the smaller interior sclerites are colourless, all others yellow.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

Both MZUC-UCCC 32684 and ZSM 20061197 are a few cm high and about 1.5 cm wide, with digitiform colony shape, although some slight swellings, which could be the beginning of lobes, are visible. Contrary to the holotype both paratypes have clubs in the base of the colony; these are up to 0.10 mm long, and similar in shape to the clubs of the top of the colony.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.

7974B36EFFBB095CB1FAB483C7BFEC15.taxon	discussion	Remarks. Alcyonium yepayek n. sp. resembles A. jorgei n. sp. with regards to the internal rods, but differs in having wider lobes and most clubs having a central wart. It also resembles A. glaciophilum n. sp. but that species has much longer rods in the interior, which are also present in the top of the colony.	en	Ofwegen, Van (2007): The genus Alcyonium (Octocorallia: Alcyonacea: Alcyoniidae) in Chile.
