Description. Colonies with little-developed stems (Fig. 1 A), usually with single distal polyp (Fig. 2 B), but branched stems, with up to three polyps observed (Figs 1 A, 2A). Stem perisarc strong (Fig. 2 A, B), mostly annulated, continuing on hydranth body as a thin film. Polyps 550–600 µm high and c. 240 µm in maximum diameter. Polyps with conical hypostome and a crown of about 12 tentacles in apparently two closely set rows (Figs 2 A, B, 3A). Tentacle distal tips apparently with concentration of nematocysts giving them appearance of slightly capitate tentacles (Fig. 3 A). Gonosome unknown. Measurements (in µm). Cnidome : heteronemes [range 8.0–9.0 x 5.0–5.5, mean 8.7±0.4 x 5.1±0.2 (n=10); ratio, range 1.6–1.8, mean 1.7±0.1 (n=10)], desmonemes [range 4.5–5.0 x 3.0–3.5]. Remarks. Although I could not clearly identify the heteronemes (discharged capsules could not be observed) in the material examined, Peña Cantero (2014b) found them in material from the same area, confirming they are microbasic euryteles [range 8.5– 9 x 5–5.5, mean 8.9±0.2 x 5.1±0.2 (n=13); ratio, range 1.6–1.8, mean 1.8±0.1 (n=13)].
