Description. ZIN 11664 is 10 cm high and 5 cm wide ( Figure 2b View FIGURE 2 ). The stem is 1.5 cm long and about 3 mm wide. Regular lateral branching forms the colony, with branches 2 mm wide. The cylindrical polyps are arranged spirally around the branches, they are about 2–3 mm high and 1 mm wide. Tentacles with scales, up to 0.12 mm long, with a few simple tubercles ( Figure 13a View FIGURE 13 ). Polyps with small clubs, up to 0.10 mm long, with simple tubercles ( Figure 13b View FIGURE 13 ). Coenenchyme with capstans, small spindles and cylinders, up to 0.12 mm long, with simple or complex tubercles ( Figure 13c View FIGURE 13 ). A few crosses are also present ( Figure 13d View FIGURE 13 ).

Distribution. Sea of Okhotsk in 300 ( Dautova 2018)— 900 m; West of Bering Sea (western Aleutian Islands) ( Figure 1c View FIGURE 1 ).

Remarks. Calcigorgia matua mostly resembles C. beringi sp. n. but has very short distinct clubs in the polyps which are lacking in C. beringi . Their distribution overlap in the West Bering Sea, but C. matua also occurs in the Sea of Okhotsk while C. beringi is only recorded from the western Aleutian Islands.
