CHN — 29.xii.2010 , S07 ( 5 m ): several stems on bryozoan host, up to 2.2 cm high, one bearing a male gonophore (MHNG-INVE-79608); 24.iii.2011 , S07 ( 3 m ): several sterile stems, up to 2.2 cm high, growing on bryozoan. Description . Colony arising from creeping, ramified hydrorhiza. Stems monosiphonic, irregularly branched, branching pattern coplanar. Perisarc ringed almost throughout, with small smooth patches. Hydranths with basal groove and ca . 22–23 filiform tentacles. Male gonophore two chambered and borne on blastostyle lacking tentacles. Female gonophores absent. Nematocysts: microbasic euryteles in two size classes: - small [(6.3–6.7)×(2.6–2.7) µm], pyriform capsules, abundant in tentacles, hydranth body and coenosarc of stem and branches; - larger [(7.7–7.8)×(3.7–3.8) µm], more ovoid capsules, in hydranth body. Remarks . The present material is rather badly preserved, the tentacle number and/or the cnidome composition could not be determined with certainty. The cnidome appears similar to that of Eudendrium sp. 1, but the mode of branching and the annulation of the perisarc are distinctive. Distribution in Chile . The present material orginates from near Corral.
