The large polychaete genus Polycirrus (Terebellida: Polycirridae) is revised based on a morphological study of the type material of most of the approximately 74 nominal species; 59 species, including a new species, P. coibensis n.sp., from the Pacific coast of Panama, are accepted as valid. All characters are reanalysed and discussed in the light of recent phylogenetic studies of terebellomorph taxa, and a standard set of characters is developed. Most of the 59 accepted species are redescribed and illustrations provided in order to facilitate future identifications of members of the genus. We designate a neotype for the type species of the genus, Polycirrus medusa Grube, 1850, and a lectotype for P. elisabethae McIntosh, 1915, in order to stabilize the concept and type locality of these taxa. A replacement name is proposed for Polycirrus kerguelensis McIntosh, 1885, which is a secondary junior homonym of Ereutho kergulenesis McIntosh, 1885, viz. Polycirrus macintoshi new name. Two species are newly synonymised: Polycirrus insignis Gravier, 1907 (senior synonym P. antarcticus (Willey, 1902)) and Polycirrus habitats Carrerette & Nogueira, 2013 (senior synonym, P. clavatus (Kinberg, 1867)). In addition, several previously synonymised species are reinstated. All available names in the genus are tabulated with type species and type localities and their taxonomic status is assessed. A key to all valid species is provided.
基于对约74个名义物种中大多数物种模式标本的形态学研究，对大型多毛纲动物Polycirrus属（蛰龙介目：Polycirridae科）进行了修订；59个物种，包括来自巴拿马太平洋海岸的一个新物种——科伊瓦Polycirrus（Polycirrus coibensis n.sp.），被认为是有效的。根据蛰龙介类群最近的系统发育研究，重新分析和讨论了所有特征，并制定了一套标准特征。对59个被接受的物种中的大多数进行了重新描述并提供了插图，以便于今后对该属成员的鉴定。我们为该属的模式物种——1850年的Polycirrus medusa Grube指定了一个新模标本，并为1915年的P. elisabethae McIntosh指定了一个选模标本，以稳定这些分类单元的概念和模式产地。为1885年的Polycirrus kerguelensis McIntosh提出了一个替代名称，它是1885年Ereutho kergulenesis McIntosh的次异名，即Polycirrus macintoshi新名称。两个物种被新归为同义：1907年的Polycirrus insignis Gravier（高级同义名P. antarcticus (Willey, 1902)）和2013年的Polycirrus habitats Carrerette & Nogueira（高级同义名，P. clavatus (Kinberg, 1867)）。此外，恢复了几个先前被归为同义的物种。列出了该属所有可用名称及其模式物种、模式产地，并评估了它们的分类地位。提供了所有有效物种的检索表。
