| Abstract |
A new species of Rhachotropis, R. northriana n. sp, is described after 4 specimens from the area of the oilfield Statfjord (61°26’N 001°55’E to 001°58’E, 270-283 m depth) in the North Sea. It is by far the smallest of Rhachotropis species from the North Sea and the only North-European species with an entire telson. It is close to Rhachotropis integricauda Ca?ra?us¸u, 1948 from the Mediterranean Sea and the Bay of Biscay, but the rostrum of both species is different: in R. integricauda it points anteriorly, whilst in R. northriana n. sp. it is directed downwards. Illustrations of the holotype of R. integricauda are given for the first time. A new identification key to North-European Rhachotropis species is given. |
