Abstract
Haploops longiseta a new Haploops species is described based on an adult female collected in the north eastern Atlantic Ocean ( Bay of Biscay) in a baited trap: IFREMER-conceived engin PROSPER left on the sea bottom at a depth of 1460m. This species is characterized by a very long seta at the end of the mandibular palp, very long dorsal setae, and a pair of long apical setae on each lobe of the telson. The pereopod 7 basis is very broad and setose on the inner side. A summarized illustrated key, based on the position of the corneal lenses, is given for the Haploops species known.References
