A reassessment of the genus Amphicteis Grube, 1850 (Polychaeta: Ampharetidae) with the description of Amphicteis teresae sp. nov. from Terra Nova Bay (Ross Sea, Antarctica)
Ampharetidae Malmgren, 1866 is a polychaete family of deposit-feeder species that flourishes in terms of individuals/m2 and species richness in areas where large quantities of food may accumulate, such as Arctic and Antarctic fjords. Despite the common occurrence of ampharetids in benthic samples an...
