Monocoryne antarctica sp. nov. (Figs 3 A, 4; Table 2) Material examined. Stn 126, one polyp, c. 13 mm long (holotype, NIWA 115613). Description. 13-mm-long polyp (Fig. 3 A). Basal 9 mm devoid of tentacles, enveloped by thin perisarc. Basal 3 mm provided with anchoring filaments. Capitate tentacles, usually in groups of three, one of them usually more developed. Gonophores absent. Cnidome consisting of stenoteles in two size groups (Fig. 4 A–B), desmonemes (Fig. 4 A, D), fusiform microbasic mastigophores? (Fig. 4 B, D) and an unidentified, relatively large, tear-shaped type (Fig. 4 C). Measurements (in µm). Cnidome: larger stenoteles [range 33– 36 x 30 –33, mean 34.8±1.0 x 31.6±0.8 (n=10); ratio, range 1.0–1.2, mean 1.1±0.1 (n=10)], smaller stenoteles [range 19– 21 x 15–16, mean 19.9±0.7 x 15.6±0.4 (n=10); ratio, range 1.2–1.4, mean 1.3±0.1 (n=10)], desmonemes [range 20–22 x 13.5–17, mean 20.8±0.7 x 14.6±0.9 (n=10); ratio, range 1.3–1.5, mean 1.4±0.1 (n=10)], microbasic mastigophores? [range 27– 30 x 13–15, ... : Published as part of ÁLVARO L.
