Paranannopus trisetosus sp.n., P. singulosetosus sp.n., P. denticulatus sp.n., P. uniarticulatus sp.n., P. variabilis sp.n., P. kunzi sp.n. and Cylindronunnopus bispinosus sp.n. are described and classified to the three evolutionary groups within the genus Paranannopus. P. variabilis, P. kunzi and P. hicksi belong to the first evolutionary group with Enp P2‐P4 3:3:2‐segmented. All three species differ from each other and the closely related species in the setation of the swimming legs P1‐P5 and to some extent in the segmentation of the Al. P. trisetosus belongs to the second group with Enp P2‐P4 2‐segmented, and it differs from the closely related P. atlanticus Coull in the setation of the segment 2 Exp P1, P4 and of the P5. P. singulosetosus, P. uniarticulatus and P. denriculutus represent the third evolutionary group with at most I‐segmented Enp P2‐P4. They differ from each other in the segmentation of the Enp P2‐P4 and the setation of the swimming legs P2‐P4 and to some extent in the segmentation of the Exp A2. Cylindronunnopus bispinosus differs from the closely related species C. elongatus (Becker et al. ) comb.n. in the setation of the P5. Updated keys are given for both genera. All species were collected at the Iceland‐Faroe Ridge from depths between 435 and 2500 m.
