- Abstract
Context: Increasing interest in mesophotic coral ecosystems has shown that reefs in deep water show considerable geomorphic and ecological variability among geographic regions. Aims: We provide the first investigation of mesophotic reefs at the southern extremity of the Great Barrier Reef (GBR) to understand the biotic gradients and habitat niches in the lower mesophotic zone. Methods: Multibeam data were used to target five benthic imagery transects collected in the lower mesophotic (80–130 m) zone from the shelf edge near One Tree Island (23°S, 152°E) by using a single HD-SDI subsea camera. Key results: Transects supported similar benthic communities in depths of 80–110 m, with the abundance of sessile benthos declining below ~110 m where the shelf break grades into the upper continental slope. Conclusions: The effect of the Capricorn Eddy may be promoting homogeneity of benthic assemblages, because it provides similar environmental conditions and potential for connectivity. Variation in benthic communities between hard and soft substrate and differing topographic relief within the study site are likely to be influenced by variation in sedimentation, including sensitivity to suspended particles. Implications: This study highlighted that the lower mesophotic region on the One Tree shelf edge supports mesophotic coral ecosystems that vary depending on depth and substrate. Increasing interest in mesophotic coral ecosystems has shown that reefs in deep water show considerable variability among geographic regions. In this study, we investigate new imagery from the lower mesophotic zone on the One Tree shelf edge to understand benthic communities and identify and map to classify habitat niches. This research provides important information on a poorly known ecosystem in the Great Barrier Reef Marine Park at a time when the oceans are rapidly changing. [ABSTRACT FROM AUTHOR]

Genus Rhipidipathes Milne-Edwards & Haime, 1857 Diagnosis. Corallum flabellate; anastomosing among some branches; polypar spines acute or blunt, smooth or tuberculate; circumpolypar spines slightly larger than interpolypar spines; hypostomal spines often equal to the circumpolypar spines but may be reduced in size or absent on some portions of the corallum. Remarks. Although Rhipidipathes is currently in the Aphanipathidae, previous (Brugler et al. 2013; Bo et al. 2018; Terrana et al. 2021) and the present study indicate that the genus is more closely related to species in the Antipathidae. The present study suggests that Rhipidipathes shares a lineage with the genus Blastopathes Horowitz, 2020 (Fig 2). Both genera have distinct morphological differences. For example, Rhipidipathes consists of thin branches that can fuse to create flabellate “fan-like” colonies (Opresko 2004) and Blastopathes consists of thick, stem-like branches that do not fuse and possess branches that sprout from clusters to create “tree-like” colonies (Horowitz et al. 2020). Due to the differences between these “sister” genera, their family-level relationships need to be verified.

Antipathes morrisi Horowitz sp. nov. (Figs. 1–3; Supplementary Tables 1–2) Material examined. Holotype, MTQ G80140, Australia, Great Barrier Reef, Orpheus Island, Pioneer Bay North, expedition Voyage of the Kalinda, collected on October 22, 2019, - 18.5998° S, 146.4888° E, 14 m depth, collector Jeremy Horowitz. Diagnosis. Flabellate corallum, up to ~ 1 cm thick; branches and terminal branchlets arranged bilaterally, or anterolaterally; overlapping, and branches anastomose. Terminal branchlets 4 to 10 mm in length, slightly curved distally, distal angles ~45 to almost 90°, 0.11 to 0.25 mm in basal diameter, spaced 2 to 5 mm apart: with a density of ~4 per cm including all rows. Spines smooth, conical, and laterally compressed, 0.085 to 0.19 mm tall. Some spines on branches possess up to four small, cone-shaped apical knobs. Four to five axial rows of spines counted in one view and four to seven spines counted in one cm in one row. Polyps 0.8 to 1 mm in transverse diameter, spaced ~ 0.2 mm apart, with eight to nine polyps per cm. Description of holotype. The entire colony was 60 cm tall by 60 cm wide and 1 cm thick (Fig. 3A), but only a 28 cm tall and 20 cm wide section (MTQ G80140) was collected. The colony is branched to the fourth and rarely fifth order and has branches and terminal branchlets that are mostly distally directed and form one distinct, ~ 1 cm thick flabellate plane with highly anastomosing branches (Fig. 3B). Branches bilaterally arranged projecting in one plane with the smaller branchlets occurring unilaterally or bilaterally in two lateral or rarely anterolateral rows. Branches range from ~0.3 to ~ 1 mm in diameter excluding spine heights. Terminal branchlets are mostly 4 to 10 mm in length, have basal diameters ranging from 0.11 to 0.25 mm, and are spaced 2 to 5 mm apart on one side of a branch resulting in about 8 to 10 terminal branchlets per cm, counting terminal branches on both sides of the branch. Branches and terminal branchlets form ~45 to almost 90° distal angles and can be almost straight or slightly curved upwards. Spines on terminal branchlets are smooth, conical, and laterally compressed. Spines are slightly distally inclined or perpendicular to the axis with convex proximal sides, and tips curved slightly upwards (Fig. 3C). On terminal branchlets with diameters from 0.11 to 0.25 mm, polypar spine heights range from 0.12 to 0.19 mm and abpolypar spine heights range from 0.085 to 0.11 mm (Fig. 3C). On lower order branches, spines are more conical and can possess two to four small conical knobs 0.01 to 0.03 mm tall, concentrated near their apexes that are directed in the same general direction as the spine. On a section of a branch 0.22 mm in diameter, polypar spines are 0.13 mm and abpolypar spines are 0.1 mm (Fig. 3D). Four to five axial rows of spines can be counted in one view of branches and terminal branchlets and four to seven spines can be counted in one cm, in one row. Polyps are yellow to brown in color, oblong in shape, and occur on one side of the colony, in one row. Polyps are 0.8 to 1 mm in transverse diameter and spaced ~ 0.2 mm apart resulting in about nine polyps per cm (Fig. 3E). Comparative diagnosis. Twenty-one out of 67 nominal species possess flabellate planar corallums with anastomoses. Of this number, Antipathes clathrata Pallas, 1766 and Antipathes tristis (Duchassaing, 1870) have very vague original descriptions that lack sufficient taxonomic information to clearly separate these two species. All other species can be distinguished from the new species. Antipathes delicatula Schultze, 1896 and Antipathes ceylonensis (Thomson & Simpson, 1905) are more loosely branched than the new species. Antipathes atlantica Gray, 1857, A. ceylonensis, Antipathes gracilis Gray, 1860, Antipathes indistincta (van Pesch, 1914) and Antipathes rhipidion Pax, 1916 form only rare occasional anastomoses, whereas the new species form a densely anastomosing fan. Antipathes craticulata Opresko, 2015, Antipathes dubia (Brook, 1889) and Antipathes plana Cooper, 1909 have uniserial arrangement of terminal branchlets throughout the corallum in contrast to new species, that demonstrate characteristic biserial arrangement (Fig. 3B). The new species is also different than A. craticulata by having less distinctly curved branches and terminal branchlets. Antipathes hypnoides (Brook, 1889), Antipathes minor (Brook, 1889), Antipathes sibogae (van Pesch, 1914), and Antipathes elegans (Thomson & Simpson, 1905) have polyps less than 0.5 mm in transverse diameter compared with 0.8 to 1.0 mm in the new species. The new species is also different than A. hypnoides by having much more regularly spaced terminal branchlets and a lower density of terminal branchlets (4 per cm vs> 9 per cm). Antipathes assimilis (Brook, 1889), Antipathes flabellum Pallas, 1776 (sensu Terrano et al., 2021), Antipathes irregularis (Thomson and Simpson, 1905), Antipathes ternatensis Schultze, 1896, Antipathes zoothallus Pax, 1932 and Antipathes speciosa (Brook, 1889) have rather small spine heights 0.09 mm and less, whereas the new species has polypar spines 0.12-0.19 mm and abpolypar spines 0.008 5 to 0.11 mm. The new species is also different than A. flabellum by having branches projecting perpendicular to the colony plane, narrower distal angles (45° vs 79°), and spines that are more perpendicular. The new species has some similarities with Antipathes aculeata (Brook, 1889) including fused branches and short spines with sharp and sometimes forked tips. However, the new species differs from A. aculeata regarding the colony thickness where the new species is only 1 cm thick because branches and terminal branchlets are arranged bilaterally forming a distinct fan-shape while A. aculeata forms a dense mass of branches resembling a bush. Also, the new species has a smaller terminal branchlet basal diameter compared to A. aculeata (0.11 to 0.25 mm vs 0.3 mm). The new species also has some features similar with Arachnopathes ericoides (Pallas, 1776) like fused branches and short branchlets slightly curved upwards; however, as with A. aculeata, the new species forms a fan while Ar. ericoides forms a thick and dense mass, like A. aculeata. Additionally, Ar. ericoides has spines that can be forked and inclined in different directions, including downwards, and can lack longitudinal rows (Terrana et al. 2020) while the new species has spines that are not forked but can be slightly multi-knobbed, not proximally directed, and form distinct longitudinal rows along branches and terminal branchlets. This new species is phylogenetically similar to A. falkorae sp. nov. and Ar. ericoides; however, A. morrisi sp. nov. and Ar. ericoides have fused branches while A. falkorae sp. nov. does not contain any fused branches (see description below). A. falkorae sp. nov. also contains longer and straighter branches that form fronds rather than the single fan characteristic of A. morrisi sp. nov. The morphological differences are sufficient to separate the species and the phylogenetic comparison does not include holotype or topotype specimens for most species being compared with the new species in the Antipathidae, which should be done in future studies that are devoted to species delimitations. Etymology. In recognition of the Morris Family Foundation that funds research at the Orpheus Island Research Station where the new species was first found and collected. Distribution.

Spines on terminal branchlets are distinctly curved apically and rarely basally. Five to six axial rows of spines can be counted in one view. Surface of spines extensively tuberculated, especially from about the midpoint to the apex. Polyps roundish, 0.8 mm in transverse diameter. Interpolypar space 0.1 to 0.2 mm, with 10 polyps per cm. Description of holotype: Colony flabellate and about 20 cm wide and 20 cm high based on estimations from in situ images (Figs. 5A–B). Collected sample about 7 cm wide and 9 cm tall. Longest branches are ~ 8 cm in length and have 0.1 cm basal diameter. Terminal branchlets are 0.5 to 1 cm in length, arranged bilaterally, and are either irregularly alternate, opposite, or subopposite. Branchlets often not strictly bilateral but slightly protrude from the general plane of the colony forming ~120° interior angles. Most terminal branchlets form ~80° distal angles and are slightly curved distally (Fig. 5B). There is extensive fusing among branches and terminal branchlets (Fig. 5C). Four anastomosing branches/branchlets can be counted in a 5 cm 2 fragment of a colony. Terminal branchlet basal diameter is 0.08 mm, distance between neighboring terminal branchlets ranges from 1 to 3 mm, and about 10 branchlets can be counted per cm of a branch, counting branches in both rows. On a branch 0.2 mm thick, polypar spines are anisomorphic with circumpolypar spines ranging from 0.23 to 0.29 mm tall and hypostomal and interpolypar spines reduced to 0.11 mm. Abpolypar spines are uniform in height, ranging from 0.13 to 0.15 mm (Fig. 5D). Polypar spines on branches are positioned mostly perpendicular to the axis or slightly distally inclined and abpolypar spines are more distally directed than polypar spines, creating ~45° distal angles (Figs. 5D–E). Six to 10 conical and apically directed tubercles can be counted in lateral view of the polypar spines, including those on the edges (Fig. 5E) and three to six tubercles can be counted in lateral view of abpolypar spines, with the proximal surface of all spines being mostly smooth (Figs. 5C–D). Tubercles become elongated and strongly appressed to the surface of the spine as they increase in size, reaching a maximum size of 0.03 mm (measuring the distance from the base of the tubercle to the apex of the tubercle). Tip of largest tubercles up to 0.004 mm above the spine surface (Fig. 5E). On thin branchlets (0.08 to 0.095 mm in diameter), circumpolypar spines are 0.13 mm tall, oriented perpendicular to the axis, and are distinctly curved upward (Fig. 5D, right image). On thin branchlets abpolypar spines are 0.11 mm tall, distally directed and are curved upward. On thin branchlets, a maximum of three tubercles can be counted in one lateral view of the surface of polypar and abpolypar spines, with the proximal surface of all spines being mostly smooth. On branches and terminal branchlets, five to six uneven axial rows of spines can be counted in one view. Polyps are pink, roundish with equally developed tentacles, and sagittal tentacles positioned slightly lower than lateral tentacles (Fig. 5B). On terminal branchlets and branches, polyps occur in one row; however, polyps can be arranged in several rows along thicker branches near the base of the colony. Polyps are ~ 0.8 mm in the transverse diameter and spaced 0.1 to 0.2 mm apart, resulting in 10 polyps per cm. Tentacles are approximated from in situ images to be 0.15 mm in length, when extended. Comparative diagnosis. This is the third nominal species in the genus Rhipidipathes. Rhipidipathes reticulata (Esper 1795) and Rhipidipathes colombiana (Opresko & Sánchez 1997) are similar in most features (See Table 1 for comparison of three species); however, R. colombiana has limited anastomosing branchlets, hypostomal spines that are only minimally reduced in size, and spines with almost no tubercles while R. reticulata has greater anastomosing branchlets, reduced hypostomal spines, and possesses tubercles on polypar spines. The new species is morphologically and phylogenetically most similar to R. reticulata by having highly anastomosing branchlets and terminal branches, reduced hypostomal spines and clear presence of tubercles on spines. The new species is different from R. reticulata by having thinner terminal branchlets (0.08 vs 0.22 mm in the type) and has spines on terminal branchlets that are distinctly curved, mostly upward but sometimes downward, not found in R. reticulata. See comparison of spines on a terminal branchlet between R. helae sp. nov. (Fig. 5D, right image) that possesses upward curved spines and R. reticulata holotype (Fig. 5F) that possesses straight spines. Additionally, the new species has a greater number of tubercules on polypar and abpolypar spines than R. reticulata (six to 10 vs three to seven tubercles in one view of a polypar spine, and three to six vs zero to three tubercles in one view of an abpolypar spine). Etymology: From the Norse, “hel”, goddess of death, who is depicted wearing a headdress of curved deer antlers that resemble the distinctively curved spines of the new species. Distribution.

Hexapathes bikofskii Horowitz sp. nov. (Figs. 1–2 and 7; Supplementary Table 1 and Table 2) Material examined: Holotype. MTQ G80122, Australia, Great Barrier Reef, Noddy Reef, expedition Schmidt Ocean Institute R / V Falkor Seamounts, Canyons, and Reefs of the Coral Sea expedition 200802, ROV Subastian dive S0398, collected on October 15, 2020, 13.5174° S, 144.1012° E, 789 m depth, collector Jeremy Horowitz. Paratype. MTQ G80024, Australia, Coral Sea, Herald Cays, expedition Schmidt Ocean Institute R / V Falkor Seamounts, Canyons, and Reefs of the Coral Sea expedition 200802, ROV SuBastian dive S0376, collected on August 08, 2020, - 16.9095° S, 149.1601° E, 638 m depth, collector Jeremy Horowitz. Diagnosis: Colony monopodial, unbranched, and pinnulate. Pinnules arranged in two lateral rows and one anterior row. Basal-most pair of lateral pinnules subopposite, other lateral pinnules alternating. Striatum present from 1 cm above basal plate to first anterior pinnules. Lateral pinnules simple, up to 12 cm long, densities of six to 10 per 3 cm counting both rows. Anterior pinnules simple, 0.8 to 1.2 cm in length, densities of 11 to 15 per 3 cm. Polyps 4 to 6 mm in transverse diameter. Description of holotype (G80122): Colony is monopodial and pinnulate with a slight sickle shape curvature of the stem (Fig. 7A). Grooves and ridges on the stem are present from 1 cm from the basal plate to the first anterior pinnule. Colony is 23 cm tall and 17 cm wide. Unpinnulated section of the stem is 4 cm and the pinnulated section of the stem is 19 cm (Fig. 7A). The specimen has two rows of lateral pinnules where the bottom pair of pinnules are subopposite and positioned perpendicular to the stem. Above the bottom pair of pinnules, pinnules are arranged alternately with distal angles ranging from ~80° at the bottom of the pinnulated section to ~20° at the top; with most pinnules having 45° distal angles. Lateral pinnules are curved forward and then backward so that the pinnule tips face in the opposite direction from the anterior pinnules. Lateral pinnules increase in length from the lowest pair of pinnules, which are ~ 8.5 cm, to midway up the pinnulated section where the longest pinnules are 12 cm, and then decrease towards the apex where the most distal pinnules are ~ 3 cm. Lateral pinnules are ~ 0.5 mm in diameter near the attachment point, and distances between pinnules in each row range from 5 to 10 mm (increasing in distance distally), resulting in 10 lateral pinnules counted near the bottom of the pinnulated section of the stem and six pinnules counted near the top of the pinnulated section, per 3 cm counting lateral pinnules in both rows. Anterior pinnules are simple, in one row and range from 0.8 to 1.5 cm in height, with most up to 1 cm in height. Distance between anterior pinnules range from 2 to 3 mm, resulting in 11 to 13 anterior pinnules counted per 3 cm. Spines on lateral pinnules are 0.025 to 0.1 mm in height, smooth, triangular, and distally directed (Fig. 7B). Lateral pinnule spines are spaced 0.45 to 0.7 mm apart in each row, and two spines can be counted per mm in one row. Four axial rows of spines can be counted in lateral view (Fig. 7B). Spines on anterior pinnules are smooth, triangular to conical, and distally directed. Spine heights are variable, ranging from 0.04 to 0.08 mm, and the distance between spines in one row is about 0.25 mm. Three to four axial rows of spines can be counted in one view of anterior pinnules. Polyps are ~ 4 to 6 mm in the transverse diameter and 6 to 8 polyps counted per three cm. Description of paratype (G80024): The colony is monopodial and pinnulate with a slight sickle shape curvature of the stem (Fig. 7C) and has two rows of distally directed lateral pinnules. Grooves and ridges are present along the stem from 1 cm above basal plate to the first anterior pinnule. Colony is 13 cm tall and 13 cm wide. The unpinnulated section of the stem is 4 cm and the pinnulated section is 9 cm in height. The lowest pair of pinnules are suboppositely arranged and are positioned almost perpendicular to the axis. All other pinnules are alternating and have distal angles ranging from ~20 degrees proximally to ~80 degrees distally. Lateral pinnules increase in length from the lowest pair of pinnules, which are 4 cm, to midway up the pinnulated section where the longest pinnules range from 6. 5 to 8 cm, and then decreasing towards the apex where the highest pair of pinnules are ~ 3 cm (Fig. 7C). Distances between pinnules range from 5 to 9 mm (increasing in distance distally), resulting in eight pinnules (near the top of the pinnulated section of stem) to 10 pinnules (near the bottom of the pinnulated section of stem) per 3 cm, counting lateral pinnules in both rows. Lateral pinnules are 0.3 mm in diameter near the attachment point. Anterior pinnules are simple, in one row with lengths ranging from 0.5 to 1 cm, with most pinnules being close to 1 cm (Fig. 7D). Anterior pinnules begin from the same height on the stem as the second lowest lateral pinnules, and extend to 5 mm above the most distal lateral pinnule. Anterior pinnules are 0.18 mm in diameter near the attachment point, and distances between pinnules range from 2 to 4 mm, resulting in 13 to 15 pinnules per 3 cm. Spines on lateral pinnules 0.05 mm in height and are smooth and triangular (Fig. 7E). Lateral pinnule spines have distances between spines in one row from 0.48 to 0.7 mm and two to three spines can be counted in one mm in one row. Five axial rows of spines can be counted in one view. Spines on anterior pinnules are smooth, triangular to conical, and distally directed (Fig. 7F). Spine heights are variable, and range from 0.02 to 0.07 mm and distances between spines in one row range from 0.32 to 0.45 mm. Three to four axial rows of spines can be counted in one view of anterior pinnules. Polyps are in a poor state of preservation and estimated based on in-situ images to be reddish in color and 6 mm in the transverse diameter. Comparative diagnosis. H. bikofskii sp. nov. is different than other species in Hexapathes by having only one row of simple (unpinnulated) and short (maximum of 1 cm in the new species vs maximum of 6 to 11 cm in currently described Hexapathes spp.) and straight anterior pinnules. See Table 2 for comparison of species in the genus. The new species is like H. australiensis Opresko, 2003 and H. alis Molodtsova, 2006 by having just one row of anterior pinnules; however, the anterior pinnules of both species are subpinnulated while the new species has simple anterior pinnules. The new species is like H. hivaensis Molodtsova, 2006 and H. heterosticha Kinoshita, 1910 by lacking anterior subpinnules; however, both species have two or more rows of anterior pinnules while the new species only has one row of anterior pinnules. Another difference between the new species and currently described species in the genus is the length of the unpinnulated section of the stem (ranging from 2 to 2.5 cm in described species vs 4 cm in the new species). The new species shares other features with H. australiensis for the following morphometrics: 1) distance between lateral pinnules on one side of the stem (0.5 to 1 cm vs 0.4 to 1.1 cm in H. australiensis), both of which have spaces greater than the other three described species, and 2) the basal diameter of lateral pinnules is 0.3 to 0.5 mm in the new species and 0.5 mm in H. australiensis), both of which are smaller than the other three described species. The two specimens representing the new species form a clade sister to H. heterosticha; however, the other species in the genus have yet to be sequenced. Specimens representing species in the genus Hexapathes should be sequenced to further investigate morphological boundaries between species. Etymology: In recognition of lead author’s grandfather, Morton Isaiah Bikofsky, a high school teacher whose passion for science fuelled JH’s interest in research. Distribution. Known only from the Great Barrier Reef and Coral Sea from 638 to 789 m depth.

Antipathes falkorae Horowitz sp. nov. (Figs. 1–2 and 4; Supplementary Table 1) Material examined. Holotype, MTQ G80067, Australia, Great Barrier Reef, Ribbon Reef Canyons, Schmidt Ocean Institute R / V Falkor, Seamounts, Canyons, and Reefs of the Coral Sea expedition FK200802, ROV SuBastian dive S0385, collected on August 18, 2020, - 15.3968° S, 145.7934° E, 111 m depth, collector Jeremy Horowitz. Diagnosis. Colony fan-like, with unilateral and sparse branching mostly to the second and third order; terminal branchlets 3 to 5 cm long and curved proximally forming 45° distal branch angles. Spines conical, mostly smooth with distinct apical knobs, secondary knobs, and some papillae on the apical section of spines 0.15 to 0.17 mm tall. Four to five axial rows of spines counted in one view. Polyps 0.8 to 1 cm in transverse diameter and eight polyps per cm. Description of holotype. Specimen is fan-like and 21 cm in height (lowermost 5 cm or more of the stem and the holdfast not collected); branched mostly to the second and rarely to the third or fourth order, with stiff and straight or slightly curved vertically directed branches (Figs. 4A–B). Distal branch angles are mostly 45°. Branching is sparse and in one plane, with mostly one and sometimes two or three branches occurring on a given lower order branch. Branching is unilateral with successive orders of branches often arising on the same side as the lower order branches. The five most basal branches are disposed on one side of the stem with subsequent branches disposed on the same side as lower order branches, while the four most apical branches occur on the opposite side of the stem and have higher order branches disposed on the same side as their direct lower order branches (Fig. 4B). The one branch between the five most basal and four most apical branches is disposed on the same side as the basal branches but has secondary branches occurring on both sides of the branch. Terminal branchlets are 3 to 5 cm in length and 0.19 to 0.2 mm in diameter near the base (Fig. 4B). The lowest portion of the stem is 0.9 mm in diameter. Spines on a branch 0.2 mm thick or greater have polypar spines 0.15 to 0.17 mm tall and abpolypar spines 0.1 to 0.15 mm tall (Fig. 4C). On branches 0.20 mm in diameter, spines are about 0.14 mm tall (Fig. 4D), and on terminal branchlets 0.2 mm or less in diameter, spines are at most 0.13 mm tall (Fig. 4E). Spines on large (about 0.2 mm or thicker) branches have extensive apical knobbing with knobs reaching maximum heights of 0.04 mm (Fig. 4F). Where knobbing is most pronounced, spine tips flare outward (at right angles to the direction of the branch axis) and become vertically compressed with small secondary knobs occurring on primary knobs (Fig. 4G). Faint papillae can be seen on and in between well-developed knobs (Fig. 4G). Spines on terminal branchlets less than 0.2 mm in diameter have few or no apical knobs, and are smooth, triangular, slightly distally directed, laterally compressed. Four to five axial rows of spines can be counted in one view; 3.5 to 4 spines can be counted in one mm; and distances between axial rows range from ~0.3 to 0.4 mm. Polyps are yellow to white in color, 0.8 to 1 mm in the transverse diameter with about 0.5 mm space between polyps resulting in about eight polyps in one cm (Fig. 4H). Comparative diagnosis. A. falkorae sp. nov. is most like Antipathes coronata Opresko, 2019 by having straight and vertically directed branches, unilateral branching, slightly larger polypar than abpolypar spines, and apical knobs on the spines. However, the new species has more extensive apical knobbing where on a spine ~ 0.14 mm tall, the new species has five to six primary knobs compared to A. coronata, which has three knobs. The new species also has small protrusions that could be considered secondary knobs on top of primary knobs that are absent on A. coronata. The new species has on average a smaller terminal branchlet diameter than A. coronata (0.2 vs 0.3 mm); however, both species have ~5 axial spine rows visible in a lateral view. The new species also has slightly wider distal branch angles that create more of a fan shape compared to A. coronata. Lastly, the new species has very faint papillae on and in between primary and secondary knobs, which differs from A. coronata that has smooth knobs. Antipathes elegans Thomson & Simpson 1905 and A. gallensis Thomson & Simpson 1905 are also morphologically like A. falkorae sp. nov. where both have apical knobbing on the spines and faint papillae on the surface of the spines; however, the new species is different from both species by having more extensive knobbing (about six knobs per spine vs three to four in A. elegans and A. gallensis) and a presence of secondary knobs that are lacking in these other species. This new species is phylogenetically similar to Ar. ericoides and A. aculeata (Supplementary Table 3); however, the new species does not possess fused branches while Ar. ericoides and A. aculeata have high levels of fused branches. Additionally, the specimens representing A. aculeata are not holotype or topotype specimens, which explains why they do not form a monophyletic relationship. The new species also has a low phylogenetic distance with A. morrisi sp. nov. and a feature that unites the two new species is a presence of apical knobs on the spines. However, A. morrisi sp. nov. has fused branches, unlike A. falkorae sp. nov. Etymology. In recognition of the Schmidt Ocean Institute R/V Falkor, onboard which this and many other black coral species were collected from the Great Barrier Reef and Coral Sea. Distribution. Known only from the Great Barrier Reef at 111 m depth.

Genus Antipathes Pallas, 1766 Diagnosis (after Opresko 2019). Corallum sparsely to densely branched. Branching bushy, bramble-like, broomlike, or fan-shaped. Terminal branchlets of varying length; arranged irregularly, or bilaterally.

Antipathes dichotoma Pallas, 1766 Type Locality. Mediterranean Sea Remarks. Antipathes dichotoma is the type species of the Antipathidae; however, molecular studies (Bo et al. 2018; Brugler et al. 2013), including this study (Fig. 2), have found that the species is more closely related to species in the Aphanipathidae than the Antipathidae.

Blastopathes Horowitz gen. nov. (Figures 2–8; Tables 1–2) Diagnosis. Corallum sparsely branched to the third and sometimes fourth order, not pinnulate. Branches long (up to 1.3 m) and spaced far apart (distances between first order branches and second order branches range from 210 cm to 560 cm) and occurring singly or in verticil-like clusters of varying numbers (as many as 10). Stem and branches thick (up to 6 mm diameter) and rigid. Each branch extending out at their base perpendicular to the stem and lower order branches from which they arise, and then curving upward with distal ends being straight or curved. One branch can extend directly upwards from the center of the cluster. Spines triangular or conical, laterally compressed, smooth, up to 0.34 mm tall. Polyps, ~ 1.25 mm in transverse diameter, ~6 polyps per cm in one row. Sagittal tentacles (~ 8 mm in length, extended) are more than twice the length of lateral tentacles (~ 3 mm in length, extended). Remarks. Blastopathes morphologically resembles Allopathes Opresko & Cairns, 1994, which also has stemlike branches coming from a singular location on the corallum (Opresko & Cairns 1994). However; Blastopathes differs from Allopathes by having branch clusters that do not necessarily occur near the base of the stem and in having more than one branch cluster (Figures 2 A–2B). Additionally, the abpolypar spines of Blastopathes are triangular, smooth, and distally slanted while all spines of Allopathes are conical with conical tubercles near the apex (Figures 2 C–2D). Other genera that contain sparse and elongate branches are Pteropathes Brook, 1889, Hillopathes van Pesch, 1910, and in the genus Antipathes, Antipathes dichotoma Palla, 1766; however, none contain branch clusters. Lastly, Blastopathes contains a stiff and non-pinnulate stem and branches that resemble unbranched genera Pseudocirrhipathes Bo et al., 2009, Cirrhipathes de Blainville, 1830, and Stichopathes Brook, 1889, all of which differ from Blastopathes by lacking branches. Molecular results. The mitochondrial igrN sequences for specimens NMAG 1893 and NMAG 1895 consisted of 482 base pairs. The two specimens shared identical sequences across 465 comparable bases. The complete igrN alignment consisted of 47 sequences, 682 bp, and included species from all seven black coral families. In the 682 bp alignment there were 274 parismony informative site (40%). Targeted capture data for 33 specimens that spanned six of the seven families in the Antipatharia, resulted in a total number of raw reads ranging from 44,898 to 3,603,888. One sample (10 raw reads, C705) was removed due to sequencing failure. Quality control and adapter trimming resulting in a mean of 1,606,997 ± 1,640,018 SD trimmed reads per sample. Trimmed reads were assembled into a mean of 927 ± 154 SD contigs per sample. The total number of matched UCE/exon loci was 2,309 with an average base pair length of 752 (ranging from 83 to 18,423 base pairs). The 75% taxon occupancy matrix included 286 loci that were concatenated into an alignment with a total length of 111,929 base pairs. A total of 36,052 parismony informative (PI) sites were identified (32% of total sites), with an average of 126.06 PI sites per locus.Alignment were also constructed for the for the holotype specimen (MTQ G74904) and the two paratype specimens (NMAG 1893 and NMAG 1895). The total number of matched loci across the three samples was 1,290 with an average base pair length of 623 (ranging from 189 to 4,068 bp). A complete (all three samples present in each loci) concatenated matrix included 792 loci, with a total alignment length of 499,264 base pairs. There were 3,855 variable sites (~0.7% of total sites) among the three samples. Despite the difference in species-level sampling, the maximum likelihood phylogenies displayed similar topologies for both alignment types (igrN, UCE/exon). In both cases, the new genus formed a distinct clade within the family Antipathidae and members of the genera Cirrhipathes and Antipathes formed separate monophyletic groups (Figures 3 A–3B). Differences between the two trees include the UCE/exon tree suggesting that Arachnopathes Milne Edwards H., 1857, and Stichopathes also share a common ancestor with Blastopathes, while in the igrN tree Stichopathes is more closely related to another lineage containing members of the Aphanipathidae Opresko, 2004, than to Blastopathes. Etymology. From the Greek “blastos”, germ, sprout, or shoot, in reference to the branch cluster features, and the commonly used suffix “pathes”. From the Latin “Medusa” in reference to thick and upward curving branches, like the snakes on the mythical gorgon’s head. Type material. Holotype, MTQ G74904, Papua New Guinea, Bismarck Sea, West New Britain Province, Kimbe Bay, Vanessa’s Reef, 35m depth, 13 March 2019 (SEM stubs MTQ G74906 to MTQ G74910, schizo- holotype NMAG 1892).

Type locality. Kimbe Bay, Papua New Guinea. Latitude: -5.305; Longitude: 150.124 Description. The holotype is a 1.2 m tall specimen that branches to the third order (Figure 4). The stem is 0.6 m in length, 6.3 mm in diameter near the base, and 4 mm in diameter just below the first branch cluster. First branch cluster occurs at the apex of the stem and consists of 10 elongate branches extending in different directions (Figure 5A) of varying lengths (maximum length 1.3 m) and diameters (none thicker than the stem). One first order branch is 0.6 m in length, 4 mm in diameter near the base, and 2 mm in diameter just below a second order branch cluster consisting of ~10 branches (Figure 5B), with a maximum branch length of 50 cm. Another first order branch is 1.3 m in length, 3 mm in diameter near the base, and 0.5 mm at the branch tip and does not produce a branch cluster. Another first order branch extends from the center of the branch cluster and extends 0.9 m directly upwards with a branch thickness of 4 mm near the base and 2 mm just below a second order branch cluster consisting of four branches with a maximum branch length of 65 cm. Another first order branch extends 5 cm, is 2 mm in diameter near the base and increases to 2.5 mm just below what resembles a new branch cluster consisting of three branches of different lengths and thicknesses. The longest of the three branches coming from the 5 cm branch is 0.6 m in length, 1.5 mm in diameter near the base, and 0.5 mm diameter near the tip. The second longest branch is 0.42 m in length, 0.2 mm in diameter near the base, and 0.1 mm near the tip. The shortest of the three branches is 5 cm in length, 0.8 mm in diameter near the base, and The spines (Figures 6 A–6C) on the branches and stem are smooth and laterally compressed. Polypar spines are 0.2 mm– 0.34 mm tall, are conical at right angles to branch axes with rounded apexes, and spines are spaced ~ 0.45 mm in one row (Figure 6A). Abpolypar spines are 0.12 mm– 0.24 mm tall and are triangular with distally slanted proximal edges and perpendicular or proximally slanted distal edges, and spines are spaced ~ 0.38 mm in one row (Figure 6B). Seven to eight, sometimes offset rows of spines can be counted in one view of a branch and stem, and approximately three spines can be counted in 1 mm of a spine row on a branch (Figure 6C) and stem. The polyps (Figures 7 A–7B), olive in color when alive, are arranged in a single row on thin branches (Figure 7A), and in multiple rows on the stem and thick branches (Figure 5A). In-situ measurements reveal that lateral tentacles (~ 3 mm in length, extended) are less than half the length of sagittal tentacles (~ 8 mm in length, extended) (Figure 7A). Polyps range 0.5 mm– 1.38 mm in transverse diameter and are spaced ~ 1 mm apart, resulting in approximately five polyps per 1 cm in one row (Figure 7B). The sizes of contracted and extended polyps are quite variable. ......continued on the next page MTQ—Museum of Tropical Queensland; TMAG—Tasmanian Museum of Art and Gallery; NMNH—Smithsonian National Museum of Natural History; RBINS—Royal Belgian Institute of Natural Sciences; CAS—California Academy of Sciences; ND—Not Deposited; DNA—Data Not Available. The paratypes (Figures 8 A–8E) range from 0.4 m to 0.5 m in height. The stem lengths range from 3 to 10 cm in length from basal plate to the first branch cluster. All paratypes have branch clusters (Figures 8 A–8C), 7 to 8 rows of compressed spines, tall and conical polypar spines, and triangular distally slanted abpolypar spines (Figure 8D), with polypar spine heights ranging from 0.14 mm to 0.3 mm and abpolypar spines ranging from 0.1 mm to 0.2 mm. About five polyps per 1 cm with lateral tentacles less than half the length of sagittal tentacles, with varying polyp sizes like the holotype (Figure 8E).
