Four Pseudopolydora Czerniavsky, 1881 species from European and adjacent waters are distinguished and a key to their identification is provided. Pseudopolydora antennata (Claparède, 1868) is redescribed based on material from the type locality, Gulf of Naples, Italy. Pseudopolydora pulchra (Carazzi, 1893) (type locality in the Gulf of Naples) is also redescribed based on material from Italy. Most previous records of the Asian P. paucibranchiata (Okuda, 1937) from North European waters are herein referred to a new species, P. nordica sp. nov. The latter differs from P. paucibranchiata by the absence of an occipital antenna on the prostomium and yellow ramified chromatophores on palps. Native to the Northwest Pacific, P. paucibranchiata was first recorded in European waters from the Tyrrhenian Sea, Lazio, Italy, in 1978. Since then, the species has spread widely in the Mediterranean and in 2015 was first recorded from northern Europe in the Netherlands.

区分了来自欧洲和邻近水域的四种假单胞菌Czerniavsky，1881种，并提供了对其进行识别的关键。根据意大利那不勒斯海湾地区的材料，对假多孢天线（Claparède，1868年）进行了重新描述。Pseudopolydora pulchra（Carazzi，1893）（那不勒斯海湾的典型地点）也根据意大利的资料进行了重新描述。来自北欧水域的亚洲P. paucibranchiata（Okuda，1937）的大多数先前记录在此都称为新物种，即P. nordica sp.。十一月 后者不同于P. paucibranchiata由于在s骨上没有枕状触角，而在触头上没有黄色的分支色谱。Puc paucibranchiata原产于西北太平洋，于1978年首次在意大利拉齐奥的第勒尼安海的欧洲水域中记录。此后，该物种在地中海广泛传播，2015年在荷兰的北欧首次记录该物种。 。
