Abstract
Five cruises to the Faroe Bank in the northeast Atlantic revealed a rich loriciferan fauna inhabiting shell gravel to fine carbonate sand. This paper describes two new species of Pliciloricus found at depths of 120–260 m. Currently, only six species of this genus have been described from various localities around the world, but several new species are currently being described. The diagnosis of the genus Pliciloricus is emended to include the two new taxa. The first of the two new species Pliciloricus leocaudatus sp. n. is characterized by having four new kinds of scalids in the second row and an additional row of alternating plates in the eighth row. The second species Pliciloricus shukeri sp. n. is characterized in having a secondary double organ in the third row. The morphology of the two species, including the new structures, has been investigated using LM and scanning electron microscopy. Conclusively, the scalid pattern of the introvert of Pliciloricus has been re-evaluated, due to the finding of the new structures. Additionally, a discussion of the life cycle of the genus Pliciloricus is given, since the postlarval stage is reduced in both new species.
