Material examined. Stn. MEL 03 —08.iii.2005, 20– 30 m, S51: one fertile colony, epizoic on Obelia dichotoma , 1 slide ( MHNG INVE 53226 ) .

Type locality. Likely unknown.

Description. Colonies composed of tortuous, creeping stolon giving rise to numerous hydrothecae and gonothecae. Hydrothecae with short, spirally grooved pedicels (generally with 2–6, but up to 10 twists have been observed); pedicels shorter than hydrothecae. Hydrotheca long, cylindrical, with lateral walls almost parallel, narrowing basally. Operculum conical, formed by several triangular flaps, each with crease-line basally; often folded inwards. Gonotheca ovoid, smooth-walled, on short pedicel composed of 1–2 annuli; basal part slightly tapering, apical part truncated, with large, rounded aperture. Gonothecal contents badly preserved.

World distribution. Cosmopolitan in coastal waters, mainly known from the northern hemisphere where it occurs on European coasts, Mediterranean, northern Canada, Alaska, Greenland, Iceland, Russian northern seas, California ( Calder 1970); in the southern hemisphere it was recorded from Japan and Newfoundland ( Schuchert 2001a).

Records from Chile. The present material was collected at only one station, from Canal Betecoi, Melinka. This is the first record for Chile.
