摘要

从韩国南海采集到一个属于 Caprellidae Leach, 1814 科 Pseudaeginella Mayer, 1890 属的新种。新种 Pseudaeginellacarinaspinosasp. 在形态上与 Paradeutella Mayer, 1890 属和 Pseudaeginella 属的相关同属种相似，都具有背侧突起、三节下颌腭、小臼齿或无臼齿以及单节第 3 和第 4 趾。不过，该新种与其同属种的区别在于背侧突的位置和大小。这是包括韩国在内的西北太平洋地区的第一个 Pseudaeginella 记录，同时还提供了 Pseudaeginella 属的物种检索表。

First record of the genus Pseudaeginella Mayer, 1890 (Crustacea, Amphipoda, Caprellidae) with a new species from Korean waters.

A new species of the genus Pseudaeginella Mayer, 1890 belonging to the family Caprellidae Leach, 1814 was collected from the South Sea in Korea. Pseudaeginellacarinaspinosasp. nov. is morphologically similar to related congeners belonging to the genera Paradeutella Mayer, 1890 and Pseudaeginella, in having dorsal projections on pereonites, triarticulate mandibular palp, small or absent molar, and uniarticulate pereopods 3 and 4. However, this new species is distinguished from its congeners by the position and size of dorsal projection. This is the first record of Pseudaeginella from the Northwest Pacific region, including Korea, and a key to species of the genus Pseudaeginella is also provided.
