A revision of the known Antarctic species of the genus Halecium has been carried out, based on the study of both type and non-type material. For each species a list of synonyms, a diagnosis, a broad description (with the exception of the recently described H. frigidum and H. exaggeratum), a discussion of its relationship with other members of the genus, and an account of its autecological data are given. Thirteen Antarctic species of the genus, including H. pseudodelicatulum sp. nov. and H. pseudoincertus sp. nov., are considered valid. Halecium tubatum is considered as species inquirenda. Halecium ovatum and H. macrocaulus are considered to be junior synonyms of H. interpolatum and H. incertus, respectively. The presence of H. delicatulum and H. tenellum in Antarctic waters is questioned. All Antarctic records found in the literature have been checked. The cnidome proved to be a useful tool for species identification in some cases. Finally, a general survey of the geographical and bathymetric distribution of the species is presented.
基于对模式标本和非模式标本的研究，对已知的南极海氏苔藓虫属物种进行了修订。针对每个物种，列出了异名清单、诊断、详细描述（最近描述的冷海氏苔藓虫和夸大海氏苔藓虫除外）、与该属其他成员关系的讨论以及其个体生态学数据说明。该属的13个南极物种被认为是有效的，包括新物种假精致海氏苔藓虫和假不确定海氏苔藓虫。管海氏苔藓虫被视为有待进一步研究的物种。卵形海氏苔藓虫和大茎海氏苔藓虫分别被认为是间插海氏苔藓虫和不确定海氏苔藓虫的次异名。南极水域中是否存在精致海氏苔藓虫和纤细海氏苔藓虫受到质疑。已对文献中发现的所有南极记录进行了核查。刺胞囊在某些情况下被证明是物种鉴定的有用工具。最后，给出了该物种地理和深度分布的概述。
