| Summary: | The Anonyx compactus group is characterized by the morphology of the inner ramus of the second uropod, which is of normal length and depth but is completely constricted distally and bears a long spine at the constriction. This group comprises eight species of which three, Anonyx attenuatus, Anonyx stappersi, and Anonyx stebbingi, are newly described. Anonyx stappersi was identified as Chironesimus debruyni by L. Stappers and A. stebbingi as A. ampulloides by T. R. R. Stebbing. Seven of these species are known from the North Pacific region, and three from the North Atlantic region, but none has a circumpolar distribution. |
