Acryptolaria is a worldwide genus of deep-water benthic hydroids. The genus has relatively high species diversity, with 36 species described so far, yet most of them have been reported only occasionally. As a result, scientific knowledge of their ecology and distribution is scarce. Here I present the results of the study of species of Acryptolaria collected during several Antarctic and sub-Antarctic expeditions under the United States Antarctic Research Program between 1958 and 1986. Eight species were found in the collection (plus one determined to the genus level), with A. operculata having the highest occurrence. Acryptolaria flabellum is reported for the second time; the study also represents the third record for A. corniformis and A. minuta. Despite the scarcity of records, most of the species studied seem to have a wide geographical distribution, which could be related to their deep-water bathymetric distribution and the deep-water circulation of the Great Ocean Conveyor Belt.
隐螅属是一种分布于全球的深水底栖水螅类动物。该属具有较高的物种多样性，迄今已描述了36个物种，但其中大多数仅偶尔被报道。因此，关于它们的生态和分布的科学知识非常匮乏。在此，我展示了1958年至1986年期间在美国南极研究计划下的几次南极和亚南极考察中收集的隐螅属物种的研究结果。在这些样本中发现了8个物种（另有1个确定到属级），其中盖形隐螅的出现频率最高。扇形隐螅是第二次被报道；该研究也是角形隐螅和微小隐螅的第三次记录。尽管记录稀少，但大多数被研究的物种似乎具有广泛的地理分布，这可能与它们的深水深度分布以及大洋输送带的深水环流有关。
