A New Record of Campylaspis fusiformis (Crustacea: Cumacea: Nannastacidae) from Korea

This study dealt with cumacean specimens collected from the shallow waters of the South Sea and East Sea, Korea. Campylaspis fusiformis Gamo, 1960 belonging to the family Nannastacidae is newly recorded to Korean fauna. This species resembles C. pumila and C. striata in having a similar body form and a pair of narrow lateral sulcuses on the carapace, but it is easily distinguished from them by the dactylus of the pereopod 2 which is more than 3.5 times the length of the propodus and bears many setae (about 20) on the surface. This species mainly occurs in the Korean and Japanese waters.
