A newly recorded species, Aora pseudotypica Hirayama, 1984, belonging to the family Aoridae Stebbing, 1899 was collected from Geomundo and Jejudo Islands in South Korea. This species is characterized by having large triangular process on basis of male gnathopod 1. It is morphologically similar to A. typica Krøyer, 1845, but distinguishable by the lack of a large rounded process on the anterior margins of basis and ischium on male gnathopod 1 and having small distal segment on outer ramus of uropod 3. To date, only two genera, Aoroides Walker, 1898 and Grandidierella Coutière, 1904, of the family Aoridae have been recorded in Korea, so this is the first record of the genus Aora from Korea.

A newly recorded aorid species, Paragrandidierella minima Ariyama, 2002, from Korean waters is reported with a description and illustrations, and its generic features are considered. This species is characterized by the carpochelate gnathopod 1 in matured male, the posterodistal protrusion on peduncle 5 of antenna 2, the absence of the apical spine on inner plate of maxilliped, the minute apical projection on inner lobe of lower lip, the acute posteroproximal extension on the basis of each pereopod 5 and 6, the shape of uropods and telson, and the large inter-ramal process of uropod 1. This is the first report of the genus Paragrandidierella from Korea.

Two aorid amphipods, Aoroides ellipticus Ariyama, 2004 and A. semicurvatus Ariyama, 2004 from shallow waters of South Korea are reported here. Aoroides ellipticus has the characteristic setation of gnathopod 1 and the elliptical shape of basis on pereopod 7, while A. semicurvatus can be easily distinguished from congeners by combined characters of the curved propodus on gnathopod 2 and the absence of marginal spines on outer ramus of uropod 3 in mature males. This paper redescribed these two aorids and provided a key to Korean Aoroides species.
