Record. QM G337403, one microslide. Coll: off Bermagui, New South Wales , 36.418 S, 150.8 E, 3980 m, beam trawl, 26/5/2017 .

Description. Three damaged stolonal hydrothecae creeping on stem of Zygophylax concinna . Stolon fragmented, very thin, tubular. Hydrothecal pedicel long, unsegmented. Hydrotheca long, expanding from a narrow conical base to diaphragm then gradually becoming tubular. Diaphragm a distinct perisarcal ring. Margin circular, rims fragmented.

Perisarc thin and fragile.

Remarks. Although there are no hydrothecae with intact margins, sufficient remains to provide an estimate of marginal diameter. Although morphologically similar to Hebella ritchiei Vervoort, 1966 (= Lafoea tenellula Ritchie, 1911 ) from coastal New South Wales, the hydrothecae of the present material are much larger. The material is inadequate to ascribe it to a new species.
