Digitogorgia brochi sp. nov. Figures 8–12 Thouarella (Euthouarella) brucei , Broch, 1965: 27 –28, pl.4, fig. 11–13. Material examined. Holotype: NHM B969, “Brategg” Expedition, “Tromso-Tral 2”, 54º43’S, 60º14’W, Burdwood Bank, SubAntarctic, 111.5 m depth, 0 9 March 1948. Description of the holotype. Fragment of a colony (Figure 8 A), probably a main side branch, of 16 cm in total height and about 4.5 cm in width, with simple branchlets (Figure 8 B) up to 3cm in length arising all around the branch forming a bottlebrush shape. Axis brown. Main side branch basal axis diameter 2.3 mm. Main stem basal axis diameter 2.9 mm. Polyps (Figure 9) on branchlets in whorls of 3, 4–5 whorls per cm, directed upwards. Polyps relatively elongate, slightly clavate, about 1.6–2.2 mm in height and 0.6–0.8 mm in diameter. Polyp body with eight complete longitudinal rows of scales, those in adaxial rows slightly smaller. About 6–7 scales in each adaxial row (Figure 10 A) and 12–13 scales on each abaxial row (Figures 9 B, 10C). Adaxial rows slightly disorganized basally, but without any reduction in number of rows (Figure 9). Accessory operculars (Figure 11 A) eight in number, 0.25–0.44 mm in height and 0.08–0.14 mm in width, more or less triangular and pointed. Proximal inner surface tuberculate, covering about 20–50% of their length, distal inner surface smooth. Outer surface quite granular with several warts on the most proximal portion. Basal margin with digitate processes. Opercular scales (Figure 11 B) eight in number, 0.30–0.45 mm in height and 0.16–0.24 mm in width, more or less triangular or oval shaped. Proximal inner surface tuberculate, covering around half of their length, distal surface smooth without keel or thorn. Proximal outer surface granular with several warts on the most proximal part, distal portion quite smooth. Basal margin often with long digitate processes, free margin entire laterally but digitate apically. Marginal scales (Figure 11 C) eight in number, 0.33–0.43 mm in height and 0.23–0.46 mm in width, ...
