Two thecate hydroids, Carpocladus fertilis Vervoort Watson, 2003 (family Aglaopheniidae Marktanner-Turneretscher, 1890) and Gonaxia constricta (Totton, 1930) (family Gonaxiidae Maggioni, in Galea Maggioni, 2021), are recorded for the first time from off New Caledonia, thus outside their original area of distribution in New Zealand waters. Specimens of both sexes of C. fertilis occur in the present collection, allowing the first description of its so far unknown female gonothecae. The trophosome of G. constricta, the only known to date, is thoroughly redescribed, pending the discovery of its gonothecae.
两种有囊螅的水螅体，Carpocladus fertilis Vervoort Watson，2003（Aglaopheniidae 家族 Marktanner-Turneretscher，1890）和 Gonaxia constricta（Totton，1930）（Gonaxiidae 家族 Maggioni，in Galea Maggioni，2021），首次从新喀里多尼亚近海被记录到，因此超出了它们在新西兰水域的原始分布范围。本采集标本中存在 C. fertilis 的两性个体，从而首次描述了其迄今为止未知的雌性生殖囊。目前已知的唯一一种 G. constricta 的营养体被彻底重新描述，等待其生殖囊的发现。
