03C987EEFFEBFFE6FF51FC05416AFBFF.taxon	description	Description. Colony. Holotype in situ large, non-planar with a disc-shaped calcareous holdfast and branches dichotomously branched in different planes forming a tree-shaped colony (Fig. 3 A). Holotype broken and incomplete after collection with the holdfast not recovered (Fig. 3 B). Internodes up to 13 cm long, sometimes hollow. Nodes brown and short, concave inward. Terminal branchlets slender in situ, up to 55 cm (Fig. 3 B). Coenenchyme thin and white after fixation (Fig. 3 C). Polyps. Polyps turreted and cylindrical with an expanded distal part and an obvious constriction below the tentacular part, usually 3 – 6 mm in height and 2 – 5 mm in width (Fig. 3 C – E). Polyps pink to orange after collection, and became white with brown color occurring on the distal part of the polyps after fixation. Polyps spaced widely on the branch, perpendicular to the axis or slightly tilted, arranged irregularly on all sides of the axis, up to 9 mm apart. Tentacular part conical or dome shaped with tentacles contractile and tightly folded on the distal part of polyps (Fig. 3 C – E, G). Sclerites. Sclerites densely arranged in polyps and coenenchyme, covered with more or less shallow grooves (Fig. 3 D, E).

03C987EEFFEBFFE6FF51FC05416AFBFF.taxon	discussion	Remarks. Aethisis gen. nov. is the fourth genus in the clade J 3. It is characterized by branches dichotomously branched in different planes, turreted polyps with a bare, sclerite-free area at the base of each tentacle, sclerites usually with toothed lateral edges, and flat rods and scales abundant in polyp body wall and coenenchyme. The new genus can be easily separated from Dokidisis and Explorisis because there are no scales in the polyp body wall and coenenchyme of the latter two genera (Lapointe & Watling 2022, Periasamy et al. 2023). Aethisis gen. nov. is similar to genus Jasonisis in sclerite forms, also including rods, needles and scales. However, the Jasonisis species have a planar colony and are covered by a thick tegument, have cylindrical polyps without a bare, sclerite-free area at the base of each tentacle, and the sclerites have more lobed edges, which are obviously different from Aethisis gen. nov. (Alderslade & McFadden 2012).	en	Xu, Yu, Lu, Bo, Watling, Les, Zhan, Zifeng, Wang, Chunsheng, Xu, Kuidong (2024): Studies on western Pacific gorgonians (Anthozoa: Octocorallia).

03C987EEFFECFFF9FF51F9124661FB93.taxon	description	Description. Colony. Holotype planar and flabellate with the holdfast not recovered, about 62 cm long and 68 cm wide in maximum extent (Fig. 5 E). Colonial color pink in situ and became brown after collection, with the deepest color occurring on the distal part of the polyps, and the color not changed after fixation in ethanol. Surface of the colony is almost completely covered with a layer of thick and brown tegument. Main stem calcareous and solid, about 2 cm in diameter at base. Branches usually irregularly and pseudo-dichotomously branched from the nodes and in one plane, arising at less than 90 º and tracing a distinct upward curve to eventually follow (more-or-less) the direction of the parent branch, forming a nearly lyrate pattern. Sometimes from one node three branches emerged in one plane, rarely four, occasionally producing more bushy lateral branchlets perpendicular to the colonial plane. Terminal branches bifurcated or trifurcated, with the unbranched branchlets up to 8 cm long (Fig. 5 B). Internodes up to 4 cm long, partially hollow. Nodes brown and very short, concave inward, up to 1 mm in height. Polyps. Polyps tall and narrow, forming a cylindrical shape, 2.0 – 6.0 mm high and 1.5 – 2.0 mm wide (Fig. 5 C). Polyps biserially arranged and well-spaced on branches, usually alternately but sometimes irregularly, perpendicular to the axis or slightly tilted, up to 9 mm apart. Tentacles contractile and tightly folded into the hollow oral disc or gathered on the distal end of polyps (Fig. 7). Sclerites. Sclerites densely arranged in polyps and coenenchyme, nearly smooth but often covered with more or less shallow grooves (Fig. 9 B, C). Elongated and thick scales to flat rodlets in the tentacle rachis are longitudinally and densely packed, often with slightly toothed to irregular edges, occasionally branched or crossed, measuring 62 – 174 × 15 – 75 μm (Figs. 7 A – C, 8 A). Scales in pinnules longitudinally arranged, thick and irregular, usually with an obvious medial constriction, measuring 43 – 79 × 7 – 25 μm (Figs. 7 B, 8 B). In some polyps, eight or fewer long rods / needles longitudinally arranged at the base of tentacles, extending from the upper polyp body wall and projecting beyond the contracted tentacles, occasionally covered with sparse longitudinal ridges or grooves, measuring 745 – 836 × 54 – 73 μm (Figs. 5 C, D; 6 E; 8 D). The ends of these needles / rods usually pointed and sharp, some of them nearly round with shallow grooves. Flat rods / needles in the upper polyp body wall longitudinally or obliquely arranged, slender, some of them with irregular edges and large ridge-like projections, occasionally branched or crossed, measuring 182 – 736 × 23 – 223 (Figs. 7 E, 8 E). Flat rods / needles and elongate thick scales in the basal polyp body wall usually transversely arranged, some of them with irregular edges or a slightly medial constriction, occasionally became broad and stout, and with large warts on surface, measuring 123 – 682 × 27 – 214 μm (Figs. 7 E, F; 8 F). Sclerites in coenenchyme same as the basal polyp body wall, densely arranged along the branch, usually with a slightly medial constriction, some of them branched with irregular shape, measuring 75 – 726 × 23 – 178 μm (Figs. 7 H, 9 A). Rodlets in pharynx longitudinally arranged, irregular and abundant, covered with large and blunt lateral projections, measuring 53 – 94 × 11 – 34 μm (Figs. 7 G, 8 C). Variability of paratype: Paratypes MBM 287337 and MBM 287338 both incomplete and broken after collection (Fig. 6 C). Internodes of MBM 287337 up to 6 cm with its polyps occasionally up to 8 mm in height and 3 mm in width. Internodes of MBM 287338 up to 6.5 cm and its unbranched terminal branchlets up to 20 cm long.	en	Xu, Yu, Lu, Bo, Watling, Les, Zhan, Zifeng, Wang, Chunsheng, Xu, Kuidong (2024): Studies on western Pacific gorgonians (Anthozoa: Octocorallia).

Colonies grow on rocky substrates with a solid disc-shaped calcareous holdfast in situ (Figs. 5 A, 6 A). The holotype attached with an individual of Comatulida AH Clark, 1908 in situ (Fig. 5 A). At the site of collection, the water temperatures were 2.41 – 3.07 ℃ and the salinity 35.79 – 35.80 psu. This species is relatively common across the Central Pacific seamounts as seen in images taken by Okeanos Explorer and included in the Benthic Deepwater Animal Identification Guide (https: // www. ncei. noaa. gov / maps / benthic-animal-guide /) under the name Jasonisis sp., including specimen USNM 94449 from Pensacola Seamount, south of Hawaii, 1500 m. From the NW Atlantic Ocean, specimen YPM IZ- 044573 collected from Abaco Island, Bahamas, at 1972 m, and specimen YPM IZ- 107119 from Northeast Providence Channel, Bahamas, at 2044 m, are genetically identical (mtMutS) to the Pacific specimens and so are assumed to belong to this species as well.	en	Xu, Yu, Lu, Bo, Watling, Les, Zhan, Zifeng, Wang, Chunsheng, Xu, Kuidong (2024): Studies on western Pacific gorgonians (Anthozoa: Octocorallia).

03C987EEFFECFFF9FF51F9124661FB93.taxon	discussion	Remarks: Parajasonisis gen. nov. resembles with the genus Jasonisis Alderslade & McFadden, 2012 in morphology, with the latter also with only one species J. thresheri, distributed in the southwest Pacific at water depths of 521 – 1813 m (Alderslade & McFadden 2012). Parajasonisis flabellata sp. nov. is similar to J. thresheri Alderslade & McFadden, 2012 in branching pattern, polyps and coenenchyme with thick tegument, sclerites of tentacles and pharynx. However, it differs from J. thresheri by polyps arrangement (usually alternately and biserially arranged vs. distributed on all sides of the axis), sclerites in polyp body wall (slender and flat rods / needles and thick scales with relatively regular edges and smooth surface vs. spindles and thin scales with lobed edges and warty surface), sclerites in coenenchyme with regular edges (vs. irregular and lobed) (Alderslade & McFadden 2012).	en	Xu, Yu, Lu, Bo, Watling, Les, Zhan, Zifeng, Wang, Chunsheng, Xu, Kuidong (2024): Studies on western Pacific gorgonians (Anthozoa: Octocorallia).

The new genus Dentatisis is characterized by flat rods in tentacles with toothed lateral edges and two rounded and slightly expanded ends, rods with irregular conical projections in the pharynx, granulated needles and flat rods both present in polyp body wall, which can easily separated the new species from other genera in clade J 3. There are two new species found in this genus, including Dentatisis bathyalis sp. nov. and D. projecta sp. nov., as described below. They have obvious differences in morphology, especially the sclerites in polyp body wall and coenenchyme, showing high interspecific morphological differentiation. However, they have similar sclerite forms in the tentacles and pharynx. Moreover, their mtMutS and 28 S gene sequences allow them to form their own clade with interspecific differences (see the genetic analysis before).	en	Xu, Yu, Lu, Bo, Watling, Les, Zhan, Zifeng, Wang, Chunsheng, Xu, Kuidong (2024): Studies on western Pacific gorgonians (Anthozoa: Octocorallia).

03C987EEFFF2FFFCFF51FC5D4280FD57.taxon	description	Description. Colony. Holotype incomplete and completely broken, only a few branches collected, and the holdfast not recovered, thus the colony shape unknown (Fig. 10 A). The color brown after fixation, with the deepest color occurring on the distal ends of the polyps. Only one branch can be seen arising from the nodes in a pseudodichotomous manner. Internodes smooth and hollow, and the only node brown and short, concave inward, up to 0.9 mm in height. Due to the inappropriate preservation, it is unknown whether there is a layer of tegument covering on the colony. Polyps. Polyps often expanded in both the upper and basal part, and became narrow in the medial, occasionally also narrow at the base or conical, 1.5 – 7.0 mm in height and 1.0 – 3.5 mm in width (Fig. 10 B – E). Polyps well-spaced on the branch, slightly tilted toward to the distal, usually alternately and biserially arranged, occasionally uniserially arranged on one side, up to 8 mm apart. Tentacles contractile and tightly folded over the oral disc of polyps, and the sclerites forming eight obvious white longitudinal strips between the bases of tentacles extending to the upper polyp body wall (Fig. 10 B, D). Sclerites. Sclerites densely arranged in polyps and coenenchyme, nearly smooth but often covered with more or less shallow grooves (Figs. 11, 12). Sclerites in the back of tentacle rachis are flat and thin rods longitudinally arranged, usually with irregular lateral edges and two rounded ends, measuring 117 – 224 × 18 – 51 μm (Fig. 11 E).

Dentatisis projecta sp. nov. is similar to D. bathyalis sp. nov. in the sclerites of tentacles, pinnules and pharynx, and has a close relationship with it in the mtMutS and 28 S rDNA phylogenetic trees. However, it can be easily separated from D. bathyalis sp. nov. by the abundant needles / rods and absence of scales in the sclerome.	en	Xu, Yu, Lu, Bo, Watling, Les, Zhan, Zifeng, Wang, Chunsheng, Xu, Kuidong (2024): Studies on western Pacific gorgonians (Anthozoa: Octocorallia).
