Abstract

Amphilochus manudens and Amphilochopsis hamatus are redescribed based on specimens from the BioIce, Mareano, and IceAGE programmes. The new species Amphilochus anoculus sp. n. is described based on material from the IceAGE programme and the preceding BioIce programme; it is separated from the closely related Amphilochus manudens by the absence of eyes, a symmetrically bilobed labrum, four setae on the maxilla 2 outer plate, a rounded corner of epimeral plate 3, and a robust seta at the tip of the telson. There are also clear differences in depth and temperature ranges. Amphilochopsis hamatus is shown to be closely related to Amphilochus manudens and A. anoculus and transferred to Amphilochus s. str.
