Description of the holotype

Colony ( Figure 7A View Figure 7 ) 36 cm total height and 6 cm width, bottlebrush with simple branchlets ( Figure 7B View Figure 7 ) up to 4 cm long, all around. Axis dark brownish, broken in its proximal portion, without holdfast.

Polyps ( Figures 7B View Figure 7 , 8A View Figure 8 ) straight and directly upward to branchlets, placed in whorls, three to five polyps per whorl ( Figure 8B View Figure 8 ) and seven or eight whorls per centimetre. Polyps not present on main stem. Polyps ( Figure 8 View Figure 8 ) cylindrical, about 1.00– 1.67 mm height and up to 0.49 mm diameter. Polyp body with six longitudinal rows of scales, six or seven scales on each longitudinal abaxial row ( Figure 8C View Figure 8 ) overlapping one another, and adaxial row partially naked with two or three scales ( Figure 8D View Figure 8 ).

Opercular scales ( Figure 9A View Figure 9 ) eight in number, 0.17–0.38 by 0.09–0.2 mm, triangular with acute tip or small thorn, two adaxial scales smaller. Proximal inner surface with large tubercles, covering at least half of their longitude; distal surface ridged, with a weak keel. Outer surface strongly granulated forming ridges. Basal margin with digitate processes, free margin serrated.

Marginal scales ( Figure 9B View Figure 9 ) eight in number, 0.35–0.50 by 0.19–0.29 mm, triangular with acute tip or small thorn. Proximal inner surface with large tubercles. Distal inner surface granulated forming ridges longitudinally near tip. Outer surface with transverse crest dividing the scale into two distinct parts: distal smooth and proximal tuberculate. Basal margin with digitate processes, free margin serrated.

Body scales ( Figure 10A View Figure 10 ) fan-shaped with pointed tips, 0.27–0.38 by 0.26–0.38 mm. Proximal inner surface almost completely covered by large tubercles, distal inner surface ridged. Outer surface and free margins as in marginal scales.

Coenenchymal scales ( Figure 10B View Figure 10 ) round, oval-shaped, 0.20–0.48 mm maximum length. Inner surface tuberculate, large warts, outer surface smooth. Free margin smooth or finely serrated.

Variations from holotype

The general colonial structure of the studied specimens is quite similar to that of the holotype. Single bottlebrush colonies up to 36 cm height and 7 cm width, some colonies divided basally giving up to seven main side branches ( Figure 11 View Figure 11 ) of up to 45 cm height and 6.8 cm width each, giving a total colony height of 48.5 cm and a total width of 18 cm. Branchlets simple, up to 76 mm. Branchlets quite crowded, more than 12 branchlets per centimetre, sometimes giving the false impression of being ramified at their base. Polyps arranged in three to eleven whorls, usually four to six. Whorls from four to nine per centimetre, usually six or seven. Single polyps also present on main stem. Calyces from 0.85 to 2.2 mm height and from 0.44 to 0.66 mm width, inclined towards the branchlet, composed of five to eight scales in each longitudinal abaxial row. Tentacular scales, eight in number, range from 0.24 to 0.63 mm height and from 0.07 to 0.25 mm width. Marginal scales in groups of eight, range from 0.43 to 0.85 mm height and from 0.22 to 0.5 mm width. Body wall scales range from 0.24 to 0.45 mm height and from 0.23 to 0.60 mm width; coenenchymal scales with a maximum length of 0.09–0.50 mm. Sclerites form and distribution are as in the holotype. Living colonies ( Figure 11B,C View Figure 11 ) orange in colour, while preserved colonies ( Figure 11A View Figure 11 ) have a dark brown stem and creamy white coenenchyme and polyps.

Geographical and bathymetrical distribution

At present, Fannyella abies ( Broch, 1965) is known from the South Orkney Islands (Coronation Island), South Shetland Islands (Elephant Island), the Antarctic Peninsula and Cape Adare and Possession Islands from the eastern Ross Sea ( Figure 1 View Figure 1 ) between 94 and 550 m in depth. Cairns and Bayer (2009) reported additional material and locations of this species as Fannyella (Scyphogorgia) liouvillei (at least the lots USNM 58156, USNM 82981, and USNM 82980).
