Suberites lutkenii s. str. from the High Arctic Seas (Fig. 1a–i 1) Material analyzed. Kara Sea, MMBI trawl survey 2016, st. C6-P35 (73.08N, 67.6E), depth 35 m (1 specimen; KFU-LH-2/003). Laptev Sea, MMBI trawl survey 2014, st. O-12 (75.3383N, 122.7867E), depth 45 m (1 specimen; KFU-LH-2/004); st. L-19 (75.1983N, 128.4633E), depth 45 m (2 specimens; KFU-LH-2/005). Description. Sponge subspherical, fig-shaped, slightly flattened (Fig. 1h–i 1). Surface wrinkled, corrugated, velvety.
