Hymedesmia (Hymedesmia) noramaloneae sp. nov. (Figure 9, Table 6) lsid:zoobank.org:act: D3D74DBA-258E-4FAB-8E5F-343DD3FB562B Type material. Holotype: BELUM. Mc 2015.701 Vieugue Island (65°38.758’S, 65° 12.540’W), depth 10–22 m; collected by C. Goodwin and E. Priestley, 23/02/2015. Paratype: BELUM.Mc2015.722and BELUM. Mc 2015.726 Port Charcot, Booth Island (65°03.853’S, 64° 01.868’W), depth 6–16 m; collected by C. Goodwin and E. Priestley, 23/02/2015. Other specimens: BELUM. Mc 2015.601 Grotto Island, Verdansky Base (Site 1) (65°14.615’S, 64° 15.019’W), depth 14–24 m. BELUM. Mc 2015.734 Port Charcot, Booth Island (65°03.853’S, 64° 01.868’W), depth 6–16 m. Diagnosis. Hymedesmia (Hymedesmia) with tornote ectosomal spicules (245–358 µm long) and two categories of acanthostyles (267–633 and 137–208 µm long), the larger of which are only spined for their basal third. Etymology. Named after Nora Malone, daughter of Jade Berman, who was born a few months after the expedition. External morphology. In situ appearance (Figure 9A): Very thin pale yellow encrusting sponge forming patches up to 20 cm in diameter. Surface covered with an irregular pattern of veins and pores sieves—pore sieves do not have rims so are less distinct than in many other Hymedesmia species. Preserved appearance. Firm white crust, 1 mm thick. Skeleton (Figure 9B): Hymedesmoid with a basal layer of primary and secondary acanthostyles and ascending columns (5–15 spicules thick) of tornotes. Chelae sparsely scattered throughout tissue. Spicules (for measurements of all specimens see Table 6). Primary acanthostyles (Figure 9C). With a tylote head. The head and up to the lower 1/3 of the shaft are spined with small conical spines but the majority of the shaft is smooth. The shaft is often slightly curved. Secondary acanthostyles (Figure 9D). With a tylote head. Entirely spined with small conical spines but these are densest at the head and become slightly sparser towards the tip. Ectosomal tornotes (Figure 9E, F): Anisotornotes, sometimes with one ...
