Resumen:
During 2007, 2008, and 2010, 23 specimens of an undescribed vermiform sea anemone were collected on Punta Pardelasand Fracaso Beach (Península Valdés, Argentina). The specimens have longitudinal rows of cinclides distally, all mesenteriesperfect, tentacles hexamerously arranged without acrospheres, column not divisible into regions, no marginalsphincter and no conchula. We describe these specimens as a new species within the genus Harenactis (family Haloclavidae).Harenactis argentina sp. nov. is the second species of Harenactis; it represents the first record of this genus in thesouthern hemisphere and the first record of a soft bottom-dwelling sea anemone in the Argentine intertidal zone. Furthermore,we discuss the familial placement and relationships of the genus Harenactis and other athenarian sea anemones.
