摘要

Four Haploops species collected in the North Atlantic Ocean are studied. One of them, H. islandica is a new species for the science. The three other species, H. carinata, H. setosa, H. robusta, were described from a long time, but many confusions exist about these species because their morphological nearness. The four species are described and illustrated in detail, and their distribution around the Iceland is specified.
