Holothurians of the genus Peniagone (Elasipodida: Elpidiidae) from the northwest Pacific ocean

The dataset contains occurrences of the holothurians of the genus *Peniagone* (Echinodermata:Holothuroidea:Elasipodida:Elpidiidae) in the northwest Pacific ocean published in Kremenetskaia et al. (2021). The specimens were collected in the several cruises of RV *Vityaz* and recent German-Russian cruises SokhoBio, KuramBio and KuramBio II. Specimens were collected with trawls and epibenthic sledges and preserved mainly in ethanol. The database includes records of *Peniagone dubia*, *P. mus*, *P. cf. purpurea* and two new species, *P. minuta* and *P. saveljevae*. Additionally added are the records of *Scotoplanes hanseni* and *Elpidia kurilensis* included into the phylogenetic analysis.

本数据集收录了西北太平洋海域中属 *Peniagone* 的海参（棘皮动物门：海参纲：海蕾目：海蕾科）的出现记录，这些记录由Kremenetskaia等人（2021年）发表。标本采集自“维捷茨”号船的多项远航以及近期德国-俄罗斯联合考察的SokhoBio、KuramBio及KuramBio II航次。标本通过拖网和底栖滑橇采集，主要用乙醇进行保存。数据库中包含 *Peniagone dubia*、*P. mus*、*P. cf. purpurea* 以及两种新物种 *P. minuta* 和 *P. saveljevae* 的记录。此外，还增加了 *Scotoplanes hanseni* 和 *Elpidia kurilensis* 的记录，这些记录被纳入了系统发育分析中。
