Both sexes of a new species, Stylicletodes wellsi sp. nov. (Harpacticoida: Cletodidae), are described from material collected from sediments in the East China Sea. The new species belongs to a species group whose members are characterized by an anal operculum that has a backwardly directed, median linguiform process and fifth legs that display naked or sparsely pinnate armature elements in both sexes. Within this group, S. wellsi sp. nov. is morphologically closest to S. reductus Wells, 1965 but differs primarily from its European congener in the armature pattern of P4 (both rami) and the female P5. Distribution records of all species are summarized and an updated identification key to the seven valid species in the genus is presented. Taxonomic issues related to the type species S. longicaudatus (Brady, 1880) are briefly discussed.
描述了东海沉积物中采集到的一新种，即雌雄两性的沃氏短尾细蚤（Stylicletodes wellsi sp. nov.）（桡足亚目：Cletodidae）。该新种属于一个种组，其成员的特征是肛附器具有向后指向的中线上的舌形突起，以及第五对足在两性中均具有裸露或稀疏羽状的附器元件。在该种组内，S. wellsi sp. nov. 在形态上与 S. reductus Wells，1965 最为接近，但主要区别在于其欧洲同种的 P4（两个分支）和雌性 P5 的附器模式。总结了所有种的分布记录，并提出了该属七个有效种的更新鉴定关键。简要讨论了与模式种 S. longicaudatus（Brady，1880）相关的分类学问题。
