Abstract

The year 2003 was the 20th anniversary of the description of the phylum Loricifera and of the type species Nanaloricus mysticus Kristensen, 1983, from Roscoff, France. To honour this occasion, a loriciferan of the newly described genus Armorloricus, from Roscoff, will be named after the discoverer of the phylum Loricifera, Professor Reinhardt Møbjerg Kristensen. This new species, Armorloricus kristenseni sp. nov., was found during two cruises to the Faroe Bank in the North Atlantic, in 1992 and 2001. The specimens were collected at three different stations (one in 1992 and two in 2001) all situated on the plateau itself at a depth of approximately 150 m. The adults are characterized by their elongated shape, the large lateral lorica plates, the very long, feather-like scalids in the third row, the long claspers in the male, and the wheel-like structure of the subcuticle glands inside the lorica plates on the ventral side. The Higgins-larvae are characterized by their long middorsal scalid with a hexagonal base and the small hook-shaped midventral pair of scalids in row 4. Furthermore, the long, paired, serrated scalids in row 6 and the asymmetrical basal plate with numerous teeth in row 7 are also unique characters. For an easier between-family comparison of the different scalids and rows on the introvert, the second row in the adults of Nanaloricidae has been split up into two rows, so that all adult loriciferans posses a total of nine rows on the introvert.
