Key to the identification of Agathotanaidae from the Iceland-Faroes-Shetlands sector of the North-east Atlantic. 1 Antennule three-articled; antenna one-articled; cuticle densely pitted. Agathotanais ingolfi - Antennule four-articled; antenna six-articled; cuticle shiny or weakly pitted. 2 2 Uropods largely concealed beneath pleotelson, exopod very small or absent. Paragathotanais .3 - Uropods visible from dorsal view, exopod a short or prominent fused process. Paranarthura .5 3 Cephalothorax longer than pereonites 1–2. Paragathotanais vikingus sp. nov. - Cephalothorax shorter than pereonites 1–2. 4 4 Pereonites 4–5 shorter than broad, pleotelson with pointed apex. Paragathotanais robustus - Pereonites 4–5 as long as or longer than broad, pleotelson bulbous, with rounded apex. Paragathotanais nanus 5 Uropod endopod two-articled, pereonites with distinct ‘shoulders’. Paranarthrura insignis - Uropod endopod one-articled, pereonites without ‘shoulders’.6 6 Cephalothorax as long as pereonites 1–2 combined; uropod endopod about twice as long as basal article; pereopod-1 with dis- tal propodal seta. Paranarthrura borealis - Cephalothorax shorter than pereonites 1–2 combined; uropod endopod only just longer than basal article; pereopod-1 without distal propodal seta.
