Actinostola属的物种以特征的高度可变性而闻名。本文对来自南美洲和南极洲的五个种和一个种的模式标本进行了解剖学、组织学和细胞科的比较。这些传统上使用的特征都不能清楚地区分所检查的Actinostolaspecies。因此，我提出了新的独特的分类特征，包括在体内和原位数据。本文提供了一个修订的Actinostola属的诊断和一个修订的物种列表。我接受A的同义词。excelsa、异枝草A. pergamentacea和A.中间体A. crassicornis，并拒绝A. chilensiswithA.粗角藻A.中间的我重新描述A. chilensisin详细信息，包括现场信息。A. chilensi栖息于智利南部峡湾蒙特港（41°35′35′′S，72°53′W）和普尤瓦皮（44°31′36′S; 72°32′6′W）之间22 m深处的岩石基底出露部位;最显著的特征是其相对较大的尺寸、明亮的橙色、光滑、坚韧的柱状体和大量且明显的内生触手。
Species of the genusActinostolaare known for high variability of features. Anatomy, histology and cnidae of type specimens of five species from South America and Antarctica originally described as members ofActinostolaand one species ofStomphiawere compared to specimens ofActinostola chilensiscollected during this study. None of these traditionally used features clearly distinguish the examinedActinostolaspecies. I therefore propose new distinctive taxonomic features, including in vivo and in situ data. I provide an emended diagnosis of the genusActinostolaand a revised list of its species. I accept the synonymy ofA. excelsa,A. pergamentaceaandA. intermediawithA. crassicornis, and reject the synonymy ofA. chilensiswithA. crassicornisandA. intermedia. I re-describeA. chilensisin detail, including in situ information. Specimens ofA. chilensisinhabit exposed positions of rocky substrate from 22 m depth down in south Chilean fjords between Puerto Montt (41°35′35′′S, 72°53′W) and Puyuhuapi (44°31′36′′S; 72°32′6′′W); the most conspicuous features are its relatively large size, bright-orange colour, smooth, tough column and numerous and clearly entacmaeic tentacles.
